Abstract
PURPOSE To evaluate the effect of phacoemulsification on intraocular pressure (IOP) and anterior chamber angle (ACA) morphology in primary angle-closure glaucoma (PACG). SETTING AND DESIGN A hospital-based, prospective pre- and post-interventional study was carried out in 40 PAC and PACG eyes post patent PI with visually significant cataracts. METHODS All patients underwent phacoemulsification and were evaluated for IOP control, ACA widening, and disease progression for a minimum of 6 months. Failure was defined as an IOP of >21 mmHg necessitating another intervention, including trabeculectomy and/or an increase in the required number of antiglaucoma medications (AGMs) by >1. RESULTS A highly statistically significant reduction of IOP ( P < 0.0001) was seen with an overall reduction of 42.2% over 6 months and a mean reduction of 8.9 ± 3.59 mmHg, with the requirement of AGMs reducing from 39/40 patients preoperatively to 1/38 postoperatively. Success was seen in 95% of cases, with two patients not achieving target IOP and requiring trabeculectomy. Angle widening was documented in all cases by both gonioscopy and AS-OCT, and none of the patients showed any progression in disc damage and visual field changes. CONCLUSION Early cataract surgery in ACG not only helps to control IOP and disease progression by widening angles and improving aqueous outflow but also improves visual acuity and reduces the economic burden of AGMs. It also helps in better evaluation of disease progression by both structural and functional analysis, as was documented by the improved and more reliable visual field indices.

Relationship between anterior segment biometry and primary angle-closure glaucoma in Hubei region: a retrospective case-control study. Front Med (Lausanne) 2024; 11:1418566. [PMID: 39247635 PMCID: PMC11377215 DOI: 10.3389/fmed.2024.1418566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Accepted: 08/14/2024] [Indexed: 09/10/2024] Open
Abstract
Objective To investigate the pathogenesis of Primary Angle-Closure Glaucoma (PACG) and its relationship with the anatomical structure of the anterior segment by obtaining biometric parameters using the IOL-Master 700. Methods A retrospective case-control study was conducted. Clinical data from 39 PACG patients and 40 normal controls treated at the Aier Eye Hospital affiliated with Wuhan University from January to December 2022 were collected. Anterior chamber depth (AC), white-to-white (WTW), lens thickness (LT), central corneal thickness (CCT), axial length (AL), corneal curvature (K1), corneal curvature (K2), and lens position (LP) were measured using the IOL-Master 700 to analyze the characteristics and differences in the anterior segment structure of both groups. Statistical methods included independent sample t-tests and logistic regression analysis. Results Significant differences were found in the anterior segment biometric parameters between PACG patients and normal controls (p < 0.05). Anterior chamber depth, white-to-white, lens thickness, central corneal thickness, axial length, and K2 were all related to the occurrence of PACG (p < 0.05). The occurrence of PACG was negatively correlated with ACD, CCT, and AL (OR = 0.12-0.64, p < 0.05), and positively correlated with LT. Conclusion Compared to the normal control group, PACG patients in the Hubei region have a smaller anterior segment space, narrower angles, thicker lens, thinner cornea, shorter axial length, flatter cornea, and more anteriorly positioned lens.

PLoS One 2024; 19:e0296849. [PMID: 38306318 PMCID: PMC10836673 DOI: 10.1371/journal.pone.0296849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 12/21/2023] [Indexed: 02/04/2024] Open
Abstract
This meta-analysis aims to systematically compare the efficacy between phacoemulsification (PE) combined with goniosynechialysis (GSL) and PE alone for primary angle-closure disease (PACD) patients. All the data were searched from the PubMed, EMBASE and the Cochrane Library. The Cochrane Handbook was used to evaluate the quality of the included studies. Additionally, this meta-analysis was performed by using the Revman 5.4 software. Nine randomized controlled trials (RCTs) were included in this study. Compared with PE alone group, PE+GSL could result significant reduction in the IOP (MD, 1.81; p = 0.002). In the instrumental subgroup, also more reduction of IOP was shown in the PE+GSL group (MD, 2.11; p = 0.02). In the viscogonioplasty (VGP) subgroup, there was not no statistical difference between PE alone group and PE+GSL group (MD, 1.53; p = 0.11). Also, more reduction of peripheral anterior synechiae (PAS) was shown in the PE+GSL group (MD,59.15; p<0.00001). For the change in angle open distance (AOD)500, AOD 750, trabecular-iris space (TISA)500, number of glaucoma medications and best corrected visual acuity (BCVA), there was no difference between two groups (p = 0.25, 0.35, 0.17, 0.56, 0.08). For TISA 750, more improvement was shown in the PE+GSL group (p<0.00001). Instrumental separation had better effect on lowering IOP when it combined with PE. Both instrumental separation and VGP could reduce postoperative PAS. The operation of GSL has no obvious effect on postoperative vision.

Meta-Analysis of Literature. J Clin Med 2024; 13:508. [PMID: 38256642 PMCID: PMC10816145 DOI: 10.3390/jcm13020508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/23/2023] [Accepted: 01/08/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND AND OBJECTIVES This study aimed to evaluate the effect of cataract extraction on intraocular pressure at 6, 12, and 24 months and their difference compared to the baseline in diverse glaucoma subtypes. MATERIALS AND METHODS We carried out research in the MEDLINE, Cochrane Library and EMBASE databases, as of April 2022 for relevant papers, filtered according to established inclusion and exclusion criteria. The meta-analysis evaluated the Mean Reduction and relative Standard Error in these subpopulations at predetermined times. A total of 41 groups (2302 eyes) were included in the systematic review. Due to the significant heterogeneity, they were analysed through a Random Effects Model. RESULTS We obtained these differences from baseline: (1) Open Angle Glaucoma at 6, 12 and 24 months, respectively: -2.44 mmHg, -2.71 mmHg and -3.13 mmHg; (2) Angle Closure Glaucoma at 6, 12 and 24 months, respectively: -6.81 mmHg, -7.03 mmHg and -6.52 mmHg; (3) Pseudoexfoliation Glaucoma at 12 months: -5.30 mmHg; (4) Ocular Hypertension at 24 months: -2.27 mmHg. CONCLUSIONS Despite a certain variability, the reduction in ocular pressure was statistically significant at 6, 12 and 24 months in both Open Angle Glaucoma and Angle Closure Glaucoma, the latter being superior. Data for Pseudoexfoliation Glaucoma and for Ocular Hypertension are available, respectively, only at 12 months and at 24 months, both being significant.

Abstract
PURPOSE To assess the safety, efficacy, and long-term clinical outcomes of primary customized phacoemulsification (phaco) combined with goniosynechialysis (GSL; phaco-GSL) in refractory acute primary angle closure (APAC) eyes with uncontrolled high intraocular pressure (IOP). METHODS This retrospective case series comprised 51 eyes of 42 consecutive patients with refractory APAC and high IOP who were treated using primary customized phaco-GSL at 3 hospitals in China, from 2014 to 2021. Preoperative and postoperative IOP, corrected distant visual acuity (CDVA), corneal endothelial cell density (CECD), intraoperative and postoperative complications were recorded. The safety, efficacy and subsequent long-term clinical outcomes were analyzed. RESULTS The mean CDVA (LogMAR) was improved from 1.67 ± 0.94 preoperatively to 0.23 ± 0.26 postoperatively (P < 0.001). Preoperative CECD was 2309.39 ± 541.03 cells/mm2 in 33 eyes and inaccessible in 18 eyes due to severe corneal edema; at the final follow-up, the mean CECD of all patients was 1823.50 ± 533.40 cells/mm2 (P < 0.001). The mean IOP decreased from 48.51 ± 6.25 mmHg preoperatively to 15.66 ± 2.27 mmHg at the final follow-up (P < 0.001). Among 51 eyes, additional customized procedures performed were corneal indentation in 42 eyes, epithelial debridement in 9 eyes, giant epithelial bullae view in 4 eyes, pars-plana fluid aspiration in 3 eyes, and secondary intraocular lens implantation in 7 eyes. The IOP of all eyes was well controlled eventually and 47 eyes (92.16%) were successfully treated by phaco-GSL alone. No significant intraoperative or postoperative complications were observed. CONCLUSIONS Primary customized phaco-GSL is a safe and effective surgical management strategy for patients with refractory APAC and high IOP.

Abstract
Purpose To compare the surgical outcomes of twin-site phacotrabeculectomy with Mitomycin C (MMC) in primary open-angle glaucoma (POAG) versus primary angle-closure glaucoma (PACG). Methods Prospective, comparative, observational study. Patients with visually significant cataract and primary glaucoma were divided into two groups: POAG and PACG. They underwent twin-site phacotrabeculectomy with MMC and followed up on days 1, 15, 1 month, 6 months, and 12 months. Baseline and follow-up visits were compared to find the differences in intraocular pressure (IOP), antiglaucoma medications (AGM), success rates, anterior chamber depth (ACD), and axial length (AXL). Results There were 50 eyes each in POAG and PACG groups. Mean IOP reduction from baseline to 12 months (21.22 ± 6.0 to 11.40 ± 2.8-POAG group vs 24.16 ± 7.6 to 12.42 ± 3.2-PACG group) was statistically significant in both groups (P < 0.001), but no significant difference between groups (P = 0.095). There was a statistically significant decline in the number of AGM in POAG [1.66 (0.7) to 0.38 (0.7), P < 0.001] and PACG [2.10 (0.7) to 0.70 (0.8), P < 0.001]; the decline was more in POAG (P = 0.012) at last visit. Probability of overall (complete and qualified) success at 12 months postop was 72.0% [95% confidence interval (CI): 57.4-82.4] in PACG and 84.0% (95% CI: 70.5-91.7) in POAG group. There was a significant increase in ACD and a decrease in AXL in both groups (P < 0.001). More interventions were required in the PACG group (38, P = 0.012). Conclusion Phacotrabeculectomy with MMC causes a significant reduction in IOP and improvement in biometric parameters in both POAG and PACG. Patients with PACG required more postoperative interventions, while a lesser number of antiglaucoma medications were needed in POAG patients.

Abstract
BACKGROUND Currently, there is no generally approved surgical treatment for patients with primary angle-closure glaucoma (PACG) and co-existing cataracts. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of phacoemulsification and phacotrabeculectomy in PACG patients with cataract. METHODS Diverse databases were searched, including PubMed, MEDLINE, EMBASE, Cochrane Library, Chinese Journal Full-text Database (CNKI), Wanfang database, and China Science and Technology Journal Database, for randomized controlled trials (RCTs) on phacoemulsification and phacotrabeculectomy for the treatment of PACG published up to 30 June 2021. ReviewManager (RevMan) version 5.4 software was used for the meta-analysis, and the effective quantity of measurement data was measured by the mean difference (MD) and 95% confidence interval (CI). The effect of counting data was measured by odds ratio (OR). RESULTS Our search of the databases identified 14 RCTs that satisfied the search criteria. Meta-analysis of these 14 RCTs showed that at the 1 month postoperative follow-up, intraocular pressure (IOP) of patients in the phacoemulsification group was higher than that of patients in the phacotrabeculectomy group (MD 2.04, 95% CI 1.42-2.65; P < 0.00001). However, the postoperative IOP was not significantly different between the two groups at the 3, 6, and 12 months postoperative follow-ups (P = 0.52, P = 0.51, and P = 0.05, respectively). More medications for IOP reduction were required by patients in the phacoemulsification group compared with those in the phacotrabeculectomy group at 3 months postoperation (MD 0.76, 95% CI 0.33-1.18; P = 0.0005), 6 months postoperation (MD 0.66, 95% CI 0.15-1.18; P = 0.01), and 12 months postoperation (MD 0.76, 95% CI 0.22-1.30; P = 0.006). Patients in the phacoemulsification group obtained better best corrected visual acuity (BCVA) than those in the phacotrabeculectomy group (MD - 0.17, 95% CI - 0.34 to - 0.01; P = 0.04) at 3 months postoperation, but there was no significant difference in BCVA between the two groups at 6 and 12 months postoperation (P = 0.33 and P = 0.56, respectively). The deepened anterior chamber was more obvious in patients in the phacoemulsification group versus those in the phacotrabeculectomy group (MD 0.61, 95% CI 0.03-1.18; P = 0.04). Patients in the phacoemulsification group experienced fewer postoperative complications than those in the phacotrabeculectomy group (OR 0.27, 95% CI 0.17-0.42; P < 0.00001). CONCLUSION Our results provide evidence that phacotrabeculectomy has advantages over phacoemulsification for the treatment of PACG in terms of better IOP and reduced medication need during the early stage post surgery. However, in terms of the complication risk, phacoemulsification is the more secure treatment option.

Abstract
BACKGROUND It is known that cataract extraction is associated with a significant reduction in intraocular pressure, especially in narrow angled eyes; however, the modifications of anterior segment parameters associated with this phenomenon have still not been completely defined. The purpose of this study was to evaluate changes in anterior segment anatomy and intraocular pressure after cataract surgery in non-glaucomatous eyes. METHODS AND MATERIAL This retrospective case series study included 64 eyes of 64 consecutive patients who underwent phacoemulsification with intraocular lens implantation. Anterior segment parameters and intraocular pressure were assessed and compared before and 6 months after surgery. Anterior segment imaging was performed using Casia SS-1000 anterior segment optical coherence tomography (Tomey, Nagoya, Japan). Anterior segment measurements included anterior chamber depth, anterior chamber width, anterior chamber volume, angle opening distance at 500 µm anterior to the scleral spur, angle recess area 750 µm from the scleral spur, lens vault, trabecular iris space area at 500 µm from the scleral spur, and trabecular iris angle at 500 µm from the scleral spur. Intraocular pressure was measured using the Goldmann applanation tonometer (Model AT 900 C/M, Haag-Streit, Bern, Switzerland). Anterior segment parameters and the relationship of changes in intraocular pressure were also evaluated. RESULTS All anterior segment parameters increased significantly after surgery (p < 0.05). Both angle opening distance at 500 µm anterior to the scleral spur and anterior chamber depth changes were positively correlated with the preoperative lens vault. The mean intraocular pressure significantly decreased from 14.91 mmHg (± 2.8 SD) to 12.91 mmHg (± 3.13 SD) (p < 0.001). Changes in intraocular pressure correlated negatively with values for the width of the preoperative anterior chamber (r = - 0.533; p = 0.001). CONCLUSION Cataract surgery led to significant widening of the anterior chamber angle and lowering of intraocular pressure. Further investigations are needed to better understand whether anterior chamber width may be a new independent predictive factor for reduction in postoperative intraocular pressure.

Song WK, Sung KR, Kim KE. Assessment of Iridotrabecular Contact and Its Association With Intraocular Pressure After Phacoemulsification in Primary Angle Closure. Am J Ophthalmol 2022; 249:1-11. [PMID: 36586662 DOI: 10.1016/j.ajo.2022.12.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 12/19/2022] [Accepted: 12/21/2022] [Indexed: 12/29/2022]
Abstract
PURPOSE To investigate the association between the quantitative assessment of iridotrabecular contact (ITC), measured by swept-source anterior segment optical coherence tomography (SS AS-OCT), and intraocular pressure (IOP) control after phacoemulsification in patients with primary angle closure disease (PACD). DESIGN Retrospective, clinical cohort study. METHODS Preoperative and postoperative anterior chamber angle parameters were measured using SS AS-OCT. IOP was measured preoperatively and until 6 months postoperatively. Percent IOP reduction and fluctuation after surgery were calculated, and their relationships with SS AS-OCT parameters were assessed by correlation analyses and locally weighted scatterplot smoothing (LOWESS) regression with change-point analysis. RESULTS A total of 51 eyes of 51 PACD patients were included. Preoperative ITC index and area (r = 0.626, r = 0.551), as well as changes in ITC index and area (r = 0.632, r = 0.543) after surgery, were significantly correlated with postoperative IOP reduction, after adjusting for age and gender (all P <.001). Higher postoperative ITC index (r = 0.405, P = .005) and ITC area (r = 0.460, P = 0.001) were associated with greater postoperative IOP fluctuations. Change points on LOWESS curves were observed for preoperative ITC index (33.0%) and change in ITC index (27.0%) and percent IOP reductions were significantly correlated with them above (β = 0.386, β = 0.664, all P < .001) but not below the change points. CONCLUSIONS Quantitative assessment of circumferential ITC can predict postoperative IOP control after phacoemulsification, and thus it may be used as a reference for determining lens extraction in PACD eyes.

Abstract
AIM To review the recent evidence in the literature regarding the efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in the management of pediatric and adult glaucoma. METHODS A literature search was performed in the electronic databases of PubMed, Google Scholar, Embase the Register of Controlled Trials, and Ovid Medline for studies evaluating the safety and outcomes of GATT in glaucoma. RESULTS GATT is a novel minimally invasive glaucoma surgery that allows the incision of the inner wall of Schlemm's canal increasing aqueous drainage through the physiologic outflow pathway with subsequent intraocular pressure reduction in different types if of glaucoma. CONCLUSION GATT demonstrated favorable results in a wide range of both primary and secondary open-angle and angle-closure glaucoma.

Factors Associated with Deterioration of Primary Angle Closure after Lens Extraction. J Clin Med 2022; 11:jcm11092557. [PMID: 35566683 PMCID: PMC9101945 DOI: 10.3390/jcm11092557] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 04/20/2022] [Accepted: 04/27/2022] [Indexed: 02/01/2023] Open
Abstract
The purpose of the study was to explore factors associated with glaucomatous deterioration in eyes with primary angle closure (PAC) after lens extraction, including PAC suspect (PACS), PAC, and PAC glaucoma (PACG). We retrospectively analyzed data of 77 eyes with PACS, PAC, and PACG that underwent lens extraction with more than 2 years postoperative follow-up. Postoperative glaucoma progression was analyzed by either structural (optic disc/retinal nerve fiber layer (RNFL) photographs or optical coherent tomography (OCT)) or functional (visual field (VF)) criterion. Cox proportional hazard analysis (hazard ratio (HR)) was used to determine risk factors for progression using uni-and multivariate analysis. The analysis was conducted in groups with or without glaucomatous optic neuropathy (PACS/PAC vs. PACG). Forty-one eyes with PACS/PAC and 36 eyes with PACG were included. The mean postoperative follow-up period was 3.5 ± 1.4 years. Intraocular pressure (IOP) was reduced postoperatively from 23.1 ± 14.4 to 13.4 ± 2.1 mmHg. In the PACS/PAC group, seven eyes (17.0%) showed structural progression, but none showed progression in VF. Preoperative RNFL thickness was the only risk factor for structural progression (HR = 0.928, p = 0.002) in the PACS/PAC group. In the PACG group, 24 eyes (66.7%) showed structural progression and 12 eyes (33.3%) showed VF progression. Thinner preoperative RNFL thickness (HR = 0.964, p = 0.043) and high postoperative IOP fluctuation (HR = 1.296, p = 0.011) were significantly associated with VF progression; none of the factors were associated with structural progression. Angle closure eyes with thinner baseline RNFL thickness and higher postoperative IOP fluctuation may require careful follow-up for glaucoma progression after lens extraction.

Anterior Chamber Angle Changes in Primary Angle-closure Glaucoma Following Phacoemulsification Versus Phacotrabeculectomy: A Prospective Randomized Clinical Trial. J Glaucoma 2022; 31:147-155. [PMID: 35210384 DOI: 10.1097/ijg.0000000000001977] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 12/14/2021] [Indexed: 11/26/2022]
Abstract
PRCIS We used anterior segment optical coherence tomography to investigate anterior chamber angle in primary angle-closure glaucoma (PACG) eyes following phacoemulsification and phacotrabeculectomy. Angle widening was significantly greater after phacoemulsification up to 6 months after the surgery. PURPOSE To compare anterior chamber angle following 2 common surgeries for PACG. METHODS One hundred ten glaucoma patients were evaluated in this single center, prospective, randomized clinical trial. Those with concomitant PACG and senile cataract and without a history of ocular surgery, trauma, or chronic miotic use were recruited. Monocular patients were also excluded. Finally, 52 eligible subjects were randomly assigned to phacoemulsification ("Phaco" group, 25 eyes) or phacotrabeculectomy ("Combined" group, 27 eyes) surgeries. A swept-source, anterior segment optical coherence tomography device (CASIA SS-1000 OCT) was used to image the anterior segment. Mask graders used the images to measure the following parameters before and 1 week, 1 month, and 6 months after surgery: angle opening distance at 500 µm, trabecular iris surface area at 500 µm, and trabecular iris angle at 500 µm. RESULTS There was no significant difference between study groups regarding best-corrected visual acuity, intraocular pressure (IOP), and the number of glaucoma medications in preoperative or postoperative visits (P>0.076). Also, the measured angle parameters were not statistically significantly different between the 2 groups before surgery (P>0.123). After surgery, all measured parameters were significantly increased in both groups (P<0.0001). At the 6-month follow-up, nasal angle opening distance at 500 µm was 0.383±0.027 vs. 0.349±0.017, trabecular iris surface area at 500 µm was 0.141±0.007 vs. 0.125±0.005, and trabecular iris angle at 500 µm was 40.1±12.9 vs. 34.6±3.1 in Phaco and Combined groups, respectively (P<0.0001 for all). CONCLUSIONS Anterior chamber angle widening by anterior segment optical coherence tomography was observed in PACG patients following surgery and was significantly greater after phacoemulsification compared with combined phacotrabeculectomy at all time points. Similar IOP and medication burden were noted for up to 6 months as secondary outcomes. The contribution of angle changes to the IOP-lowering effect of phacoemulsification in PACG eyes needs further study.

Abstract
Purpose To assess the outcomes of viscocanalostomy and phaco-viscocanalostomy in patients with narrow angle glaucoma at a single tertiary eye centre. Method All patients undergoing viscocanalostomy for narrow angle glaucoma between June 2010 and June 2017 with a minimum follow-up of 12 months were included. Data was analysed from a prospectively maintained surgical outcome database. Primary outcome was a change in intraocular pressure (IOP). Secondary outcomes were changes in LogMAR visual acuity, number of eye drops, post-operative complications and further surgical interventions. Success was defined at two IOP cut-off points: IOP ≤ 21 mmHg and IOP ≤ 15 mmHg with (qualified success) or without (complete success) drops. Failure was any repeat glaucoma surgery or loss of light perception. Results Seventy eyes of 46 patients with a mean follow-up of 41.31 months (range 12–60 months) were included. Mean IOP changed from 25.7 ± 9.6 to 15.2, 15.6, 14.6, 13.8 and 14.0 mmHg at 1, 2, 3, 4 and 5 years post-operatively. Drops reduced from 3.2 ± 1.1 pre-operatively to 0.5 at 1 year and 1.1 at all time points thereafter. Qualified success for an IOP ≤ 21 mmHg was achieved in 94.2%, 88.1%, 92.5%, 91.1% and 92.0% and complete success in 63.8%, 37.3%, 30.2%, 22.2% and 24.0% in years 1 to 5, respectively. Qualified success for an IOP ≤ 15 mmHg was achieved in 53.6%, 60.9%, 69.8%, 68.9% and 64.0% and complete success in 39.1%, 26.9%, 22.6%, 20.0% and 8.0% in years 1 to 5, respectively. IOP was significantly lower at all examined post-operative time points (41.1%, 39.3%, 43.3%, 46.4% and 45.3% at years 1 to 5, respectively, p < 0.001 at all time points). Four eyes (5.7%) failed to meet any of the success criteria. Of these, 3 eyes (4.3%) required further glaucoma surgery and one eye (1.4%) progressed to no perception of light at 48 months. No patients had an IOP ≤ 5 mmHg on two consecutive occasions after 3 months. Conclusion Viscocanalostomy and phaco-viscocanalostomy are a safe and effective surgical option in the management of chronic narrow angle glaucoma.

Abstract
Purpose To assess the 10-year effects of early phacoemulsification with intraocular lens (IOL) implantation in primary angle closure glaucoma (PACG) patients with cataract. Patients and Methods This prospective cohort study included 102 eyes of 102 patients with PACG. All patients had coexisting cataracts compromising vision. Patients underwent phacoemulsification and foldable IOL implantation. The main outcome measures were anterior chamber depth (ACD), angle width, value of intraocular pressure (IOP), and number of medications needed postoperatively and during follow-up. Results Half (53%) of the patients were female, with ages ranging from 55 to 73 with a mean of 59.82±5.19 years. Mean IOP decreased significantly from 22.15±2.08 mmHg at baseline to 14.08±2.13 mmHg postoperatively (p˂ 0.05). The ACD increased from 2.2±0.21 preoperatively to 3.73±0.25 postoperatively (p˂0.001). Nasal angle width increased postoperatively to 40.05±2.09 compared to the preoperative value of 16.02±2.08 (p˂0.001). Temporal angle width increased from 13.05±2.07 to 41.9600±1.94 (p˂0.001). Anti-glaucoma treatment significantly decreased postoperatively (p˂0.001). A significant positive correlation was detected between ACD and angle width, while a negative correlation was detected between IOP and both ACD and angle width (p˂0.001). There was also a significant negative correlation between postoperative angle width and IOP (p˂0.001). Preoperative lens thickness was positively correlated with preoperative IOP and number of medications, while it was negatively correlated with preoperative AC depth and angle width. Preoperative lens thickness positively correlated with postoperative IOP and medications. Complete and qualified success was achieved in 69.65% and 30.4% of cases, respectively, while 2.9% failed to be controlled. Visual acuity significantly improved from 0.17±0.1 to 0.9±0.08 (p˂0.001). All parameters showed high stability throughout the follow-up period. Conclusion Phacoemulsification with IOL implantation is a safe and effective early modality for long-term control of IOP in PACG patients with coexisting cataract. The effects can persist for at least 10 years.

Abstract
PURPOSE To compare the outcomes of phacoemulsification with phacotrabeculectomy in primary angle closure glaucoma (PACG) eyes with medically controlled intraocular pressure (IOP). METHODS Prospective, randomized control trial including 33 eyes of 33 patients who underwent phacoemulsification (Phaco) and 37 eyes (37 patients) who underwent phacotrabeculectomy (PT). The primary outcome measure was survival defined as IOP control (IOP ≥ 6 and ≤ 21 mmHg without antiglaucoma medications (AGM) at different time points. Secondary outcome measures were the rate of visual recovery and complications. RESULTS The mean age in years (PT: 58.5 ± 9.8, Phaco:61.6 ± 8.9; p = 0.16), preoperative mean deviation in decibel (PT: -18.7 ± 9.3; Phaco: -16.6 ± 7.9; p = 0.32) and the mean follow up in years (PT: 2.5 ± 1.8; Phaco: 2.8 ± 2.0; p = 0.63) were similar in the two groups. The mean preoperative AGMs were more in the PT group (PT: 2.13 ± 0.97, Phaco: 1.60 ± 0.78; p = 0.01). In both the groups the survival was similar at all-time points (PT: 78% at 1-year and 52% at 5-years, Phaco: 80% at 1 year and 59% at 5 years (P = 0.82). The postoperative visual acuity in LogMAR was significantly better in the Phaco group at 1 month (PT: 0.22 ± 0.38, Phaco:0.06 ± 0.07; p = 0.02). Postoperative AGM (p = 0.68) and rate of visual field progression PT: -0.46 ± 0.41 dB/year; Phaco: -0.38 ± 0.73 dB/year; p = 0.67) were similar in both groups. One eye in PT group developed malignant glaucoma which resolved with laser hyaloidotomy and cycloplegic therapy. CONCLUSIONS More rapid visual recovery with similar IOP control and similar visual field stability favor phacoemulsification to phacotrabeculectomy in medically controlled PACG eyes with cataract.

Graefes Arch Clin Exp Ophthalmol 2021; 259:3739-3747. [PMID: 34258655 DOI: 10.1007/s00417-021-05295-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 05/08/2021] [Accepted: 06/22/2021] [Indexed: 11/30/2022] Open
Abstract
PURPOSE To assess the accuracy of intraocular lens power calculation formulas Barrett Universal II (BUII), Hill-Radial Basis Function (RBF) 3.0, Kane, Ladas Super Formula (LSF), Haigis, Hoffer Q, and SRK/T in primary angle-closure disease (PACD). METHODS A total of 129 PACD eyes were enrolled. Prediction refraction was calculated for each formula and compared with actual refraction. Accuracy was determined by formula performance index (FPI), median absolute error (MedAE) and percentage of eyes with a prediction error (PE) within ± 0.50D. Subgroup analysis was performed according to axial length (AL). RESULTS Overall, FPI was ranked as follows: Kane (0.067), RBF 3.0 (0.064), Haigis (0.062), SRK/T (0.060), BUII (0.058), Hoffer Q (0.055), and LSF (0.049). Kane got the highest (71.3%) percentage of eyes with PE within ± 0.50 D. In medium AL eyes (22 mm < AL ≤ 25 mm), FPI ranked the same as in total group. MedAEs were equal across all formulas (P = 0.121). In short eyes (AL ≤ 22 mm), FPI was Kane (0.055), RBF 3.0 (0.050), SRK/T (0.050), Haigis (0.049), BUII (0.047), Hoffer Q (0.045), and LSF (0.033). MedAEs were significantly different across all formulas (P = 0.033). Haigis showed the lowest MedAE (0.35 D), Haigis and Kane got the highest percentage (63.6%) of eyes with PE within ± 0.50 D. CONCLUSION Kane outperformed in total PACD eyes; RBF 3.0, Haigis, and SRK/T achieved satisfying performance. When dealing with PACD eyes shorter than 22 mm, Kane achieved the best accuracy. RBF 3.0, SRK/T, Haigis, and BUII achieved comparable outcomes. No formula showed superiority over others for medium AL PACD eyes.

Comparison of Treatment Outcomes of Selective Laser Trabeculoplasty for Primary Open-Angle Glaucoma and Pseudophakic Primary Angle-Closure Glaucoma Receiving Maximal Medical Therapy. J Clin Med 2021; 10:jcm10132853. [PMID: 34203137 PMCID: PMC8268094 DOI: 10.3390/jcm10132853] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 06/17/2021] [Accepted: 06/25/2021] [Indexed: 11/17/2022] Open
Abstract
Selective laser trabeculoplasty (SLT) is a useful treatment for intraocular pressure (IOP) control. However, there are only a few reports which compare the outcomes of SLT between primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). We compared the efficacy of SLT for patients with PACG following phacoemulsification with POAG receiving maximal medical therapy (MMT). Consecutive glaucoma patients followed up for at least 1 year after SLT were retrospectively evaluated and IOP reductions at 6 months and 12 months were analyzed. Seventy-six patients were included in the analyses. The baseline IOPs in the POAG and PACG group were 18.5 ± 3.3 mmHg and 16.9 ± 2.5 mmHg, respectively, with 2.8 ± 0.9 and 2.7 ± 0.8 types of IOP lowering medication. The average IOP at the 6-month and 12-month follow-up after SLT was significantly decreased and comparable in both the POAG and PACG groups. For those with a low baseline IOP, the effect of SLT on IOP reduction at 12 months was significantly better in the PACG than in the POAG group (p = 0.003). IOP reduction at 6 and 12 months after SLT was significantly greater in those with a high baseline IOP than those with a low baseline IOP (p < 0.0065). In summary, the one-year efficacy of SLT was equivalent in POAG and pseudophakic PACG patients receiving MMT; however, SLT was more effective in eyes with PACG than eyes with POAG when focusing on those with a lower baseline IOP.

Abstract
Purpose This meta-analysis aimed to compare the efficacy and safety of phacoemulsification with goniosynechialysis (Phaco-GSL) with those of phacoemulsification alone (Phaco-alone) in patients with angle-closure glaucoma and cataract. Methods Randomized controlled trials (RCTs) were selected through a search of electronic databases. Trial eligibility and risk of bias were assessed using Cochrane review methods. Primary measures included the intraocular pressure (IOP), number of antiglaucoma medications, peripheral anterior adhesion (PAS) extent, and their pre- and postoperative changes. For continuous parameters, we calculated weighted mean differences and 95% confidence intervals. Statistical analysis was performed using RevMan 5.3 software. Results Eight RCTs were included, where 224 and 236 eyes were in the Phaco-GSL and Phaco-alone groups, respectively. Both postoperative IOP and number of medications were not significantly different between the study groups at the six- and twelve-month follow-up. However, the 12-month postoperative PAS extent was significantly smaller in the Phaco-GSL group than in the Phaco-alone group. Similarly, changes from the preoperative to 12-month postoperative PAS extent were significantly greater in the Phaco-GSL group than in the Phaco-alone group, but IOP and the number of medication changes were not different. Conclusions Our results provide evidence that Phaco-GSL provides advantages over Phaco-alone treatment regarding PAS reduction. In terms of IOP and medication reduction, both groups were comparable. Thus, Phaco-GSL can be considered for the treatment of patients with angle-closure glaucoma and cataract due to its ease, safety, and potential benefit for the anterior chamber angle.

Abstract
PURPOSE To evaluate the additional intraocular pressure (IOP) lowering effect of gonioscopy-assisted transluminal trabeculotomy (GATT) to contemporary goniosynechialysis (GSL) in endeavouring to abolish subsequent occlusion after chronic iridotrabecular contact in primary angle closure (PAC) patients. METHODS A retrospective case series of all PAC eyes underwent GATT + GSL with or without phacoemulsification and intraocular lens implantation (PEA + IOL) from December 2016 to May 2018 were recruited. IOP and the number of anti-glaucoma medications were compared pre- and post-operatively by Wilcoxon signed-rank test. Repeated measure ANOVA was used to evaluate the difference in IOP change after the operation between a subgroup of operations (GATT + GSL + PEA + IOL and GATT + GSL) and the arc of cutting of trabeculotomy. RESULTS Thirty-nine eyes of 30 patients, 37 chronic angle closure glaucoma (CACG), 1 acute primary angle closure (APAC), and 1 plateau iris syndrome were recruited. Mean preoperative IOP was 21.8 ± 5.4 mmHg. Mean post-operative IOP was lowered to 15.1 ± 3.8 mmHg at 1 month, 14.4 ± 1.2 mmHg at 3 months, 14.8 ± 2.1 mmHg at 6 months, 14.5 ± 0.8 mmHg at 1 year, and 15 at 2 years (P < 0.001, P = 0.0012, P = 0.001, P = 0.028, and P = 0.317 (n = 1), consecutively). Mean of overall post-operative IOP at the last follow-up was 15.1 ± 4.4 mmHg (P < 0.001). Mean preoperative number of anti-glaucoma medications was 3.5 ± 1.4. Mean post-operative number of anti-glaucoma medications was reduced to 1.5 ± 1.4 at 1 month, 0.9 ± 0.9 at 3 months, 1.4 ± 1.4 at 6 months, 1.5 ± 0.5 at 1 year, and 2 at 2 years (P < 0.001, P = 0.01, P = 0.002, P = 0.028, and P = 0.317 (n = 1), respectively). Mean of overall post-operative number of anti-glaucoma medications was 1.1 ± 1.2 (P < 0.001). There was no significant difference found between the IOP lowering effect in subgroup analysis. CONCLUSION GATT + GSL could significantly reduce IOP and number of anti-glaucoma medications from baseline compared to the last follow-up; however, there seemed not to be any superiority to the effects found in previous studies reported about GSL + PEA or PEA alone in PAC patients.

Development and Evaluation of the Prognostic Nomogram to Predict Refractive Error in Patients With Primary Angle-Closure Glaucoma Who Underwent Cataract Surgery Combined With Goniosynechialysis. Front Med (Lausanne) 2021; 8:749903. [PMID: 34977061 PMCID: PMC8714900 DOI: 10.3389/fmed.2021.749903] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 11/18/2021] [Indexed: 02/05/2023] Open
Abstract
Objective: To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas and develop prognostic nomograms to predict the risk of postoperative refractive error in primary angle-closure glaucoma (PACG) patients. Methods: A total of 111 eyes with PACG underwent goniosynechialysis combined with phacoemulsification and IOL implantation were included. SRK/T, Barrett II, Hoffer Q, and Kane formulas were used to predict postoperative refraction. Prediction error (PE) and absolute predictive error (APE) produced by the four formulas were calculated and compared. An APE >0.50 D was defined as the event. Binary logistic regression analysis and prognostic nomogram models were conducted to investigate reliable predictors associated with postoperative refraction. Results: The Kane (-0.06 D) and Barrett II (-0.07 D) formulas had mean prediction error close to zero (p = 0.44, p = 0.41, respectively). The Hoffer Q and SRK/T produced significantly myopic outcomes (p = 0.003, p = 0.013, respectively). The percentage of eyes within ± 0.5 D was 49.5% (55/111), 44.1% (49/111), 43.2% (48/111), and 49.5% (54/111), for the Kane, Barrett II, Hoffer Q, and SRK/T formula, respectively. Nomogram showed that AL had the greatest impact on the refractive outcomes, indicating a shorter preoperative AL is associated with a greater probability of refractive error event. The area under the receiver operator curve (AUC) of the nomogram for the Kane, Barrett II, Hoffer Q, and SRK/T was 0.690, 0.701, 0.708, and 0.676, respectively. Conclusions: The Kane and Barrett II formulas were comparable, and they outperformed Hoffer Q and SRK/T in the total eyes with PACG receiving cataract surgery combined with goniosynechialysis. The developed nomogram models can effectively predict the occurrence of postoperative refractive error events.

Abstract
PRECIS Substantial proportion of primary angle closure glaucoma (PACG) eyes showed glaucomatous worsening after successful lens extraction and intraocular pressure (IOP) control, which may suggest that an earlier intervention may be required to prevent PACG. PURPOSE The purpose of this study was to investigate the longitudinal clinical course of the primary angle closure (PAC) disease spectrum, including PAC, primary angle closure suspect (PACS), and PACG patients, who underwent lens extraction. METHODS This retrospective observational study included 77 eyes from patients with PACS, PAC, and PACG who underwent lens extraction and were followed up for >2 years after surgery. The mean, peak, and fluctuation of IOP were analyzed before and after lens extraction among groups. Visual field (VF) mean deviation was compared immediately after lens extraction and the final follow-up. Postoperative glaucoma progression determined by 3 criteria (optic disc/retinal nerve fiber layer photographs, optical coherent tomography, and VF) was compared among the 3 groups. RESULTS Seventeen PACS, 24 PAC, and 36 PACG eyes were included. The mean and peak IOP, and IOP fluctuation IOP were significantly reduced postoperatively in all groups. Postoperative VF mean deviation was significantly aggravated only in the PACG group (from -7.26 to -8.82 dB, P<0.001). The prevalence of postoperative glaucoma progression by at least 1 criterion was significantly higher in PACG, and none of the eyes with PACS and PAC showed VF conversion (PACS, PAC, PACG; 11.8%, 12.5% vs. 61.1% in disc/retinal nerve fiber layer, 11.8%, 8.3% vs. 63.9% in optical coherent tomography, 0%, 0% vs. 33.3% in VF, all P<0.001). CONCLUSIONS In the PAC spectrum, lens extraction achieved significant IOP reduction. However, despite IOP control, a substantial proportion of PACG eyes showed glaucomatous progression. This result may suggest that lens extraction should be performed early to prevent PACG.

Ophthalmol Glaucoma 2020; 4:350-357. [PMID: 33242681 DOI: 10.1016/j.ogla.2020.11.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Revised: 11/02/2020] [Accepted: 11/09/2020] [Indexed: 11/15/2022]
Abstract
PURPOSE To study the effect of phacoemulsification on intraocular pressure (IOP) control in patients with preexisting glaucoma drainage implants (GDIs). DESIGN Retrospective, observational case series. PARTICIPANTS A total of 45 patients (51 eyes) with previously placed GDIs who underwent phacoemulsification between January 2013 and March 2018. METHODS The list of patients was obtained from billing records. Clinical data were retrieved from the corresponding electronic medical records. MAIN OUTCOME MEASURES Intraocular pressure, number of glaucoma medications before and after phacoemulsification (postoperative day 1, week 1, months 1, 3, 6, 12, 18, and 24), rate of failure (failure defined as IOP >18 mmHg and IOP increase >20% at 2 consecutive visits after month 1, need for additional glaucoma surgery, or loss of light perception vision), and postoperative complications. RESULTS Mean follow-up was 23.0 ± 11.1 months. The average interval between GDI surgery and phacoemulsification was 9.4 ± 6.7 months. An Ahmed glaucoma valve (AGV; New World Medical) was implanted in 12 eyes, a Baerveldt glaucoma implant (BGI; Johnson & Johnson Surgical Vision) was implanted in 36 eyes, and a Molteno (Molteno Ophthalmic Limited) glaucoma implant was implanted in 3 eyes. Before phacoemulsification, the mean IOP was 14.4 ± 4.4 mmHg on 2.1 ± 1.3 glaucoma medications. At postoperative month 24, the mean IOP was 12.6 ± 4.4 mmHg (n = 29, P = 0.519) on 2.0 ± 1.6 (P = 0.457) glaucoma medications. The reduction in IOP was significant only at postoperative week 1 (P = 0.031). The cumulative failure rate was 3.9% at 1 year and 11.8% at 2 years. The AGV group had a significantly higher mean IOP before phacoemulsification than the BGI group (P = 0.016). Analysis of covariance, taking the baseline IOP as a covariate, revealed no differences in postoperative IOP and number of glaucoma medications between groups, except for month 18 (1 patient in the BGI group had uncontrolled IOP requiring surgery). Postoperative complications included cystoid macular edema (10%), corneal decompensation (6%), and choroidal effusion (4%). CONCLUSIONS Phacoemulsification after GDI surgery resulted in a transient reduction in IOP at postoperative week 1. Patients with previously placed AGVs had similar postoperative outcomes compared with those with BGIs.

Abstract
Purpose To investigate the outcome of phacoemulsification in selective laser trabeculoplasty (SLT)-treated eyes. Methods This retrospective study included patients who had open angle glaucoma (OAG) with previous SLT who underwent phacoemulsification. We evaluated intraocular pressure (IOP), length of glaucoma control without treatment, and antiglaucoma medication or surgery. SLT-treated eyes that did not receive phacoemulsification were retrospectively chosen as a control. We investigated factors related to outcome of phacoemulsification by multivariate analysis. Results 42 eyes with previous SLT that underwent phacoemulsification and 40 controls were retrospectively evaluated. Phacoemulsification was performed 52 ± 15 months after SLT. After a mean follow-up of 74 ± 21 months, mean IOP was significantly decreased in the phaco group by 2.2 ± 2.7 mmHg (p < 0.001). In the SLT group, mean IOP was decreased by 0.8 ± 2.8 mmHg (p < 0.001). 9 eyes (16.7%) in the phaco group and 11 eyes (19.0%) of the SLT group needed topical treatment, and no eye needed glaucoma surgery in both groups. The factor related to success was higher baseline IOP (p = 0.002). Conclusion Prior SLT didn’t negatively influence phacoemulsification in patients with OAG. Phacoemulsification lowered IOP effectively and safely in OAG patients who were treated with SLT.

Abstract
PRECIS Phacotrabeculectomy was more effective in reducing intraocular pressure (IOP) and glaucoma drugs than phacoemulsification alone in primary angle-closure glaucoma (PACG) eyes with cataract but was associated with more postoperative complications, up to 5 years after surgery. PURPOSE The purpose of this study was to compare long-term clinical outcomes of phacoemulsification versus phacotrabeculectomy in PACG eyes with cataract. PATIENTS AND METHODS The 2 initial prospective randomized controlled trials recruited PACG eyes with cataract using the same criteria and randomized these eyes to receiving either phacoemulsification or phacotrabeculectomy. Clinical data up to 5 years of follow-up were pooled for retrospective analysis. RESULTS Clinical data of 35 patients in the phacoemulsification group and 44 patients in the phacotrabeculectomy group were analyzed. At 5 years after surgery, the mean IOP was decreased by 20.7% and 29.5% from before surgery to 5 years after phacoemulsification and phacotrabeculectomy, respectively (P<0.001 for both groups). Phacotrabeculectomy was significantly more effective than phacoemulsification in reducing IOP up to 5 years after surgery (P<0.001). At 5 years, the mean number of glaucoma drugs required±1 SD was 1.6±1.2 in the phacoemulsification group, and 0.7±1.0 in the phacotrabeculectomy group (P=0.004). Phacotrabeculectomy was associated with more postoperative complications than phacoemulsification up to 5 years (25 complications in the phacotrabeculectomy group versus 6 in the phacoemulsification group, P<0.001). CONCLUSIONS Phacoemulsification alone reduces IOP and the need for glaucoma drugs in PACG eyes with cataracts for up to 5 years. Phacotrabeculectomy was more effective in reducing IOP and glaucoma drugs than phacoemulsification alone but was associated with more postoperative complications, up to 5 years after surgery.

Abstract
BACKGROUND: Phacoemulsification surgery has the ability to deeply alter the segment anterior morphology, especially in eye with shallow anterior chamber (AC), narrow anterior chamber angle (ACA). However, the changes of anterior chamber depth (ACD) and ACA on the close angle suspect eyes after phacoemulsification have not been mentioned in many studies. So, we conduct this research. AIM: To evaluate the alteration in the ACA and ACD after phacoemulsification in the close angle suspect eyes. METHODS: Interventional study with no control group. Subjects were the primary angle closure suspect (PACS) eyes, that were operated by phacoemulsification with intraocular lens (IOL) at Glaucoma Department of VNIO from December 2017 to October 2018. RESULTS: 29 PACS eyes with cataract were operated by phacoemulsification with intraocular lens. After 3 months of monitoring, the average ACD augmented from 2.082 ± 0.244 to 3.673 ± 0.222 mm. AOD500 increase from 0.183 ± 0.088 to 0.388 ± 0.132 μm, AOD750 increased from 0.278 ± 0.105 to 0.576 ± 0.149 μm. The TISA500 enlarged from 0.068 ± 0.033 to 0.140 ± 0.052 mm2, TISA750 enlarged from 0.125 ± 0.052 to 0.256 ± 0.089 mm2 at the third month (p < 0.01). CONCLUSION: Phacoemulsification surgery increases the ACD and enlarged the angle in the PACS eyes.

Abstract
Optic nerve damage and visual impairment caused by glaucoma affect 66.8 million people worldwide, and causing bilateral blindness in 6.7 million people. Surgery is the main method for the treatment of cataract with glaucoma. In recent years, clinicians have increasingly paid attention to and applied phacoemulsification and intraocular lens implantation combined with goniosynechialysis for the treatment of cataract with angle-closure glaucoma. However, for patients with complicated cataract, the high ultrasonic energy of traditional phacoemulsification can largely damage the corneal endothelium. Modified phacoemulsification (lower ultrasonic energy) and intraocular lens implantation have now achieved certain efficacy. The efficacy and safety of modified phacoemulsification plus goniosynechialysis compared with conventional surgery for cataract and glaucoma was investigated. A total of 125 patients who underwent goniosynechialysis combined with phacoemulsification and intraocular lens implantation were enrolled in the control group, while 179 patients treated by modified phacoemulsification and intraocular lens implantation combined with goniosynechialysis were enrolled in the research group. The visual acuity and intraocular pressure were observed before and 6 months after surgery in both groups, and the incidence of complications was analyzed. After treatment, there were more patients with visual acuity of 0.2-0.4 and >0.4 in the research group than in the control group (P<0.05). The incidence of corneal edema and anterior chamber inflammation was lower in the research group than in the control group (both P<0.05), while the preoperative and postoperative intraocular pressure, central anterior chamber depth, angle-opening distance, and peripheral iridocorneal adhesions were not significantly different between the two groups (all P>0.05). Modified phacoemulsification and intraocular lens implantation plus goniosynechialysis for cataract with glaucoma can better improve the visual acuity, as well as effectively reduce corneal edema and anterior chamber inflammation.

Eye (Lond) 2019; 34:40-50.

Abstract
Angle-closure glaucoma is an aggressive condition that causes millions to become blind worldwide. This review explores the use of prophylactic laser peripheral iridotomy (PI) in patients classified as primary angle-closure suspects (PACS), and additionally, the use of clear lens exchange as a primary treatment option in established angle-closure disease with or without glaucoma. As PI has a strong prophylactic effect in fellow eyes of patients who have had an acute attack, its use has been widely adopted in those patients classified as PACS, but with limited evidence to support this. A large randomised trial conducted in China has demonstrated that although PI reduces the risk of incident angle-closure disease, the incidence of disease that would threaten vision was much lower than anticipated. This suggests that the benefit of prophylactic PI is very limited. Health services data shows an association between rising cataract surgical rates and of decreasing rates of acute angle-closure. Age-related growth of the lens is a major component of angle-closure disease. Several studies have shown that clear lens extraction (CLE) effectively lowers IOP in angle-closure. The use of CLE as a primary treatment option has been tested against LPI in the EAGLE study, a large RCT that enroled people with angle-closure and an IOP > 30 mmHg, and those with angle-closure glaucoma. The trial showed CLE to be superior to PI both for IOP control and patient reported quality of life. On these grounds, CLE should be considered for first-line treatment of more advanced angle-closure disease.

Abstract
PURPOSE To examine the outcome of laser peripheral iridotomy (LPI) for primary angle closure and determine predictors of future lens extraction (LE). METHODS A retrospective chart review of 218 eyes from 128 consecutive patients undergoing LPI between 2010 and 2012 at a university hospital. Baseline factors including age, peak intraocular pressure (IOP) before LPI, diagnosis (primary angle closure suspect, primary angle closure, primary angle closure glaucoma), and acute or non-acute presentation were recorded. Patients were followed for 3.7±1.6 years. Kaplan-Meier curves were constructed to examine survival times to LE and Cox proportional hazard regression was used to identify factors associated with LE. RESULTS In total, 91 of 218 eyes (41.7%) initially treated with LPI had LE during follow-up. For eyes with non-acute presentation, 12%, 25%, and 32% had LE at 1, 2, and 3 years, respectively. For eyes with acute presentation, 27%, 42%, and 50% had LE at 1, 2, and 3 years. In univariable analysis, older age, higher IOP, worse visual field, and primary angle closure glaucoma diagnosis were associated with LE, with older age and higher IOP remaining significant in multivariable analysis. There was a 1.09-fold increased odds of LE for each year older at baseline and each 1 mm Hg higher IOP was associated with a 1.08-fold increased odds of LE. CONCLUSIONS A large proportion of patients with angle closure treated with LPI went on to require LE. Patients with features associated with higher odds of LE might be considered for LE as a primary procedure.

Abstract
OBJECTIVE The aim of this study was to evaluate the effects of goniotomy on patients with primary angle-closure glaucoma who underwent "phacoemulsification and visco-goniosynechialysis." MATERIALS AND METHODS This prospective randomized clinical trial was carried out on 63 eyes of 61 patients (48-85 years) with primary angle-closure glaucoma who were enrolled. The subjects were randomly assigned into two groups. In the first group (32 eyes) and the second group (31 eyes), the patients underwent "phacoemulsification + visco-goniosynechialysis + goniotomy" and "phacoemulsification + visco-goniosynechialysis," respectively. Intraocular pressure and antiglaucoma medication were evaluated (1 week, as well as 1, 3, and 6 months after the surgery). Anterior segment optical coherence tomography parameters (Casia, Tomey, USA) and goniotomy were evaluated preoperatively and 6 months after the surgery. RESULTS The mean intraocular pressure lowering the effects in the "phacoemulsification + visco-goniosynechialysis + goniotomy" group was higher than that in the "phacoemulsification + visco-goniosynechialysis" group (6.93 and 4.6, respectively). Furthermore, the difference in intraocular pressure between the two groups was significant at 3 months (P = 0.014) and 6 months (P = 0.021) after the surgery. There was no difference in anterior segment optical coherence tomography findings before the intervention; however, after the intervention, the anterior segment optical coherence tomography indices were significantly different between the two groups. Moreover, the difference in "phacoemulsification + visco-goniosynechialysis + goniotomy" indices was more than the changes in the "phacoemulsification + visco-goniosynechialysis" group. CONCLUSION The results of this study showed that phacoemulsification + visco-goniosynechialysis + goniotomy is a more effective surgery than phacoemulsification + visco-goniosynechialysis alone in undercounted primary angle-closure glaucoma.

Abstract
Purpose The purpose is to study the effect of cataract extraction on intraocular pressure (IOP) in patients with angle closure disease (ACD). Methods In this retrospective study, patients with ACD including medically uncontrolled and advanced primary angle closure glaucoma (PACG) who underwent only cataract surgery were included. The IOP trend was analyzed at postoperative day 1, day 7, 1 month, 3 months, 6 months, 1 year, and final follow-up along with requirement of antiglaucoma medication (AGM)/surgery. Results A total of 110 eyes of 79 patients [primary angle closure suspect (PACS): 21, PAC: 34, PACG: 55 eyes] were analyzed. Of these patients, 31 eyes had advanced PACG and 20 eyes had medically uncontrolled glaucoma. Best-corrected visual acuity >6/12 was seen in 51 eyes at baseline and 87 eyes at final follow-up. After cataract surgery alone, there was significant reduction (median) in IOP [19.1 ± 18.00% (18.8) in PACS (P < 0.01), 8.55 ± 17.9% (10) in PAC (P = 0.04), 22.82 ± 15.45%(14.3) in PACG (P < 0.01), 18.27 ± 15.99% (14.5) in advanced PACG (P = 0.01) and 36.56 ± 14.58% (28.57) in medically uncontrolled glaucoma (P < 0.01)] and AGM [51.85% (1) in PAC, 32.35% (2) in PACG, 17.71% (2) in advanced PACG, and 40.74% (1.5) in medically uncontrolled PACD] at median follow-up of 1, 2.5, 1, 1.3, and 1 year. Eleven PACG patients, who were on systemic medication preoperatively, were off systemic therapy at final follow-up, while six other PACG eyes (10.9%) required glaucoma surgery. Conclusion Cataract surgery leads to significant drop in IOP across the spectrum of ACD with visually significant cataract. Cataract surgery may be considered initially for IOP control even in advanced or medically uncontrolled PACG followed by glaucoma surgery later if required.

Abstract
Purpose To compare the effects of cataract surgery on intraocular pressure (IOP) according to preoperative factor in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Methods The medical records of 75 POAG and 95 PACG patients who underwent cataract surgery were reviewed. We classified POAG patients with a preoperative peak IOP of less than 31 mmHg and less than three medications used before surgery and PACG patients with a peak IOP of less than 42 mmHg, less than three medications used, and peripheral anterior synechiae of less than four clock hours into group 1. Patients with levels exceeding these thresholds were classified into group 2. The IOP, numbers of medications, and success rates were compared between two groups. Results At 36 months after surgery, IOP reduction in group 1 was significantly greater than that in group 2 among POAG patients (−1.7 ± 2.1 vs. −0.6 ± 2.0 mmHg, p = 0.021); however, there was no significant difference between the two groups for PACG patients (−2.5 ± 2.0 vs. −2.2 ± 3.3 mmHg, p = 0.755). The medication changes were similar between the two groups for both POAG and PACG patients. The success rate at 36 months was significantly higher in group 1 than in group 2 for POAG patients (66.7% vs. 35.7%, p = 0.009), but there was no significant difference between the two groups for PACG patients (79.1% vs. 69.2%, p = 0.264). Conclusions For patients with relatively low peak IOP who used fewer medications before surgery, cataract surgery alone was effective for IOP control in both POAG and PACG patients. Conversely, For POAG patients with a history of higher peak IOP and who used more medications, cataract surgery was not effective in lowering IOP, whereas it resulted in relatively good IOP values in PACG patients.

Abstract
Background The effect of cataract surgery on IOP in patients with primary open-angle glaucoma (POAG) is a subject of debate. We investigated the effect of cataract surgery by phacoemulsification on intraocular pressure (IOP) in patients with medically POAG . Methods Seventy eyes of 40 POAG patients undergoing cataract surgery by phacoemulsification were retrospectively evaluated. All patients had their POAG medically controlled without prior glaucoma surgery. Baseline demographics and clinical characteristics were recorded. IOP and the number of glaucoma medications were evaluated before and for 1 year after cataract surgery. We analyzed IOP variations from baseline with a Student t-test for a paired sample. We used a Pearson correlation coefficient and linear regression to study the relation between IOP change from baseline and preoperative characteristics. Results One year after phacoemulsification, IOP decreased by a mean 1.15 ± 3 mmHg (6.8 ± 18.1%) (P = 0.01) and the number of glaucoma medications remained unchanged with a difference of − 0.1 ± 0.43 (P = 0.09). Higher preoperative IOP was associated with a greater IOP decrease after 1 year of follow-up (P < 0.001). One and 7 days after cataract surgery, 12.9 and 4.2% of the eyes had IOP spikes > 30 mmHg, respectively. One year after cataract surgery, 75.7% of the POAG eyes maintained the same number of glaucoma medications while 17.1% had a decrease and 7.2% of the eyes required adding glaucoma medications. Conclusion Cataract surgery by phacoemulsification in eyes with medically controlled POAG resulted at 1 year in a very small IOP decrease without a change in the number of glaucoma medications. A drop in IOP should not be expected after performing phacoemulsification alone in POAG patients.

Abstract
AIM To evaluate the efficacy of combined treatment of phacoemulsification (PE) and micro-incisional single-port transconjunctival limited pars plana vitrectomy (PPV) in acute angle-closure glaucoma (AACG). METHODS A retrospective study included 26 patients who underwent PE diagnosed with AACG. Among them, 16 patients (16 eyes) underwent PE alone, 10 patients (10 eyes) underwent combined limited vitrectomy and PE. Then we compared intraocular pressure (IOP), anterior chamber angle, anterior chamber depth, central corneal thickness and corneal endothelial cell count before and after surgery, and effective PE time during cataract surgery. RESULTS Effective PE time was shorter in the combined surgery group than in the single surgery group (P=0.040). There was no statistically significant difference in IOP and best-corrected visual acuity between the two groups postoperatively. At 6mo postoperatively, there was no difference in the anterior chamber angle, anterior chamber depth, and central corneal thickness between two groups, but corneal endothelial cell count was higher in the combined surgery group than in the single surgery group (P=0.046). No complication such as vitreoretinal disease, endophthalmitis, bullous keratopathy was noted. CONCLUSION Combined micro-incisional single-port transconjunctival limited PPV and PE are more effective and safer than PE alone because of less operation time and fewer complications for management of AACG.

Abstract
PURPOSE To compare the anatomical effects on anterior segment by lens extraction (LE, phacoemulsification with posterior chamber intraocular lens implantation) and laser peripheral iridotomy (LPI) in primary angle closure suspect (PACS) eyes. METHODS This prospective comparative cohort trial included a total of 122 consecutive patients identified as PACS aged 52 to 80 years. LE or LPI was performed based on each patient's choice. The anterior segment optical coherence tomography (ASOCT) and gonioscopy were conducted at baseline and 4 weeks post-operation. Outcome measures include percentage of residual angle closure, mean angle width (modified Shaffer grade), angle opening distance (AOD), trabecular iris angle (TIA), trabecular iris space area (TISA), anterior chamber depth (ACD), iris curvature (I-Curve), lens vault (LV), intraocular pressure (IOP), and best-corrected visual acuity (BCVA). RESULTS All anterior angle parameters (AOD, TIA, and TISA) were significantly greater after LE than LPI (P < 0.001 for all). ACD (P < 0.001) increased, LV (P < 0.001) decreased, IOP (P < 0.001) decreased, and BCVA (P < 0.001) increased after LE. However, no significant changes were found in ACD (P = 0.782), LV (P = 0.616), IOP (P = 0.112), and BCVA (P = 0.131) after LPI. In both groups, I-Curve decreased after the operation, but the iris was flatter after LE than LPI (P < 0.001). Gonioscopically, the LE group achieved a larger post-operative angle width (modified Shaffer grade) than LPI (P < 0.001) and all anterior chamber angles were open (defined as posterior pigmented trabecular meshwork (PTM) visible with static gonioscopy) after operation. Nevertheless, after LPI, 12 eyes (20.0%) still had two or more quadrants and 32 eyes (53.3%) still had at least one quadrant in which the posterior PTM could not be observed. CONCLUSIONS Compared with LPI, LE resulted in a wider anterior chamber angle, a deeper anterior chamber, and a lower IOP in PACS eyes. Moreover, no residual angle closure was observed after LE, which could morphologically prevent the progress of angle closure. TRIAL REGISTRATION ChiCTR1800016511.

Abstract
BACKGROUND We investigated how cataract surgery might influence long-term intraocular pressure (IOP) change in both healthy subjects and glaucoma patients. METHODS A retrospective analysis of patients who had had clear corneal phacoemulsification with a minimum of 12 months of follow up was performed. Glaucoma patients with medically controlled open-angle glaucoma and healthy subjects with no glaucoma were included in the analysis. The change of IOP after phacoemulsification and factors associated with postoperative IOP change were investigated. RESULTS In total, 754 eyes of 754 patients, specifically 106 patients with glaucoma and 648 patients with no glaucoma (i.e., healthy subjects) were enrolled. The phacoemulsification effected a reduction of IOP: 1.03 ± 3.72 mmHg in healthy subjects and 1.08 ± 3.79 mmHg in glaucoma patients at postoperative 1 year (P = 0.656). There were negative coefficients of IOP until 1 year of follow up (all P < 0.001), but the IOP change gradually showed a less steeply decreasing slope (correlation coefficient: -0.993), compared with those for 1 week and 1 month of follow up (correlation coefficients: -1.893 and -1.540, respectively). In the multivariate analysis, age and preoperative IOP showed significant associations with postoperative IOP change (regression coefficients: -0.034 and 0.419 respectively, all P < 0.001). CONCLUSION Phacoemulsification resulted in IOP reduction, which effect regressed in healthy subjects and glaucoma patients over the course of long-term follow up. Therefore, long-term monitoring of IOP change is needed. In cases of higher preoperative IOP and young patients, phacoemulsification alone is a reliable option for IOP control.

Abstract
PURPOSE: Comparative clinical study of medically controlled non-severe chronic Primary Angle Closure Glaucoma (PACG) with co-existing cataract surgically managed by phacoemulsification as against combined phacotrabeculectomy. METHODS: This randomized clinical trial was conducted between December 2011 and December 2013. Patients were randomly assigned to Phacoemulsification (PE) and Phacotrabeculectomy (PT) groups for surgery. Intraocular pressure, anti-glaucoma medications, Best Corrected Visual Acuity, anterior chamber angle widening and post-operative complications in both groups were compared after 12 months. RESULTS: There were 46 eyes with PACG in PE group and 45 in PT group. The IOP at 12 months in PE group was 11.5±1.3mmHg and 11.8±1.2mmHg in PT gr. (p = 0.28). The eyes requiring single anti-glaucoma medications at 12months in PE group was 0, PT group was 1 (p = 0. 495). The post op BCVA at 12months in PE group 0.3+-0.12 and 0.33±0.15 in PT group (p = 0.22). 3 cases in PT group required additional intervention whereas no additional intervention was required in PE group and this difference was statistically significant (p = 0.116). CONCLUSION: Phacoemulsification is equally effective in terms of intraocular pressure control and visual outcome as phacotrabeculectomy with better safety and less post-operative complication.

Abstract
PURPOSE To evaluate the early-postoperative intraocular pressure (IOP) changes and frequency of IOP spike after cataract surgery in normal-tension glaucoma (NTG) eyes and to compare them with those of nonglaucomatous eyes. MATERIALS AND METHODS This was a case-control study. We reviewed the medical records of patients who had undergone cataract surgery. One-to-one (1:1) case matching was performed, each matched set consisting of 1 NTG and 1 nonglaucomatous eye as the control eye. Comparisons between those 2 groups were performed. Specifically, IOP was measured preoperatively and 1 day, 1, 2, and 4 weeks postoperatively. The incidence of IOP spike was evaluated according to the criteria of IOP higher than 21, 25, 30 mm Hg, higher than 5, 10 mm Hg over baseline IOP, and 50% above preoperative IOP. RESULTS A total of 298 eyes (149 NTG eyes and 149 control eyes) were enrolled. Preoperative IOP did not show any significant difference between the 2 groups (P=0.687). IOP significantly decreased in both the NTG and control groups [P<0.001, repeated-measures analysis of variance (ANOVA)]. No significant differences in this regard were detected between the 2 groups (P=0.618, repeated-measures ANOVA). When IOP spike was evaluated according to the 6 criteria, the frequencies were <3% at any timepoint. There was no significant difference between the 2 groups. CONCLUSIONS In both the NTG and control groups, IOP gradually decreased in the early-postoperative period after cataract surgery, and there was no significant difference between the 2 groups. The frequency of IOP spike was <5% in both the NTG group and the control group.

Abstract
PURPOSE To investigate the clinical features and efficacy of lens surgery in patients with lens subluxation misdiagnosed as primary angle-closure glaucoma. METHODS In total, 2054 inpatients with primary angle-closure glaucoma were consecutively recruited. Eighty-five of the patients were rediagnosed as lens subluxation following ultrasound biomicroscopy after hospitalization. Lens surgeries were performed in all patients, and 35 had a follow-up of at least 12 months. Risk factors of postoperative intraocular pressure control were identified with multivariate logistic regression analysis. RESULTS Eighty-five inpatients (4.1%, 85/2054) with lens subluxation were misdiagnosed as primary angle-closure glaucoma, of which 71.8% (2.97% of all cases, 61 out of 2054 subjects) had ocular blunt trauma and 18.8% (0.78% of all cases, 16 out of 2054 subjects) had spontaneous dislocation. Lens surgery significantly decreased the intraocular pressure and improved best-corrected visual acuity, meanwhile increased the anterior chamber depth (all P < 0.001). Postoperatively, the intraocular pressure was controlled with antiglaucomatous eye drops administration in 17 eyes, in which greater range of preoperative angle closure and zonular dialysis, and longer operation time delay were detected. Risk factors for poor postoperative IOP control were more quadrants of angle closure (P = 0.038) and operation time delay (P = 0.045). CONCLUSION Lens subluxation was the major cause of the misdiagnosed cases as primary angle-closure glaucoma. Misdiagnosed patients could benefit from the lens surgery, while more angle-closure quadrants and operation time delay indicated worse postoperative intraocular pressure control.

Abstract
Purpose To identify the preoperative biometric factors, including subfoveal choroidal thickness (CT), associated with refractive outcome after cataract surgery in eyes with primary angle closure (PAC). Methods This study included 50 eyes of 50 PAC patients who underwent uneventful cataract surgery. Preoperatively, anterior segment parameters including anterior chamber depth (ACD) and lens vault were determined by anterior segment optical coherence tomography. Subfoveal CT was measured by spectral domain optical coherence tomography enhanced depth imaging before and at one month after surgery. Mean refractive error (MRE) was calculated as the difference in spherical equivalent between actual postoperative refraction determined one month postoperatively and that predicted using each of three IOL calculation formulas (SRK/II, SRK/T, and Haigis). Regression analyses were performed to investigate potential associations between MRE and putative factors. Results Mean ACD was 1.9 ± 0.4 mm, and preoperative subfoveal CT was 250.8 ± 56.9 µm. The SRK/T (MRE, 0.199 ± 0.567 diopters [D]) and Haigis (MRE, 0.190 ± 0.727 D) formulas showed slight hyperopic shift, while the SRK/II formula demonstrated a myopic shift (MRE, −0.077 ± 0.623 D) compared with that expected after cataract surgery. Mean absolute refractive error was not significantly different between formulas. Higher preoperative lens vault and shallower ACD were associated with a hyperopic shift in all formulas, but not in a statistically significant manner. Thicker preoperative subfoveal choroid was associated with a myopic shift after cataract surgery in all formulas (SRK/II: β = −0.511, p < 0.001; SRK/T: β = −0.652, p < 0.001; Haigis: β = −0.671, p < 0.001). Greater postoperative reduction of subfoveal CT was associated with a myopic shift after cataract surgery in all formulas (SRK/II: β = −0.511, p < 0.001; SRK/T: β = −0.652, p < 0.001; Haigis: β = −0.671, p < 0.001). Conclusions Our results indicate that preoperative subfoveal CT and the difference between pre- and postoperative subfoveal CT are significant factors for predicting refractive error after cataract surgery in PAC patients. These findings should be considered when performing cataract surgery to optimize visual outcomes.

Abstract
Acute primary angle closure requires emergency management that involves a rapid lowering of the intraocular pressure and resolution of relative pupil block - the most common mechanism of angle closure. Emergency strategies for lowering intraocular pressure include medical treatment and argon laser peripheral iridoplasty. Anterior chamber paracentesis and diode laser transcleral cyclophotocoagulation may be considered in special situations. Relative pupil block can be relieved by peripheral laser iridotomy and primary lens extraction; the latter is a more effective treatment according to the results of clinical trials. However, primary lens extraction can be technically demanding in the acute setting. Peripheral laser iridotomy has a role in relieving pupil block and should also be considered in most cases. Lens extraction may be combined with procedures such as goniosynechialysis, trabeculectomy or endoscopic cyclophotocoagulation. In this review, we aim to discuss the available evidence regarding the different treatment modalities. We also discuss the economic consideration, including cost-effectiveness and life expectancy, in the management of acute primary angle closure.

Abstract
Primary angle closure glaucoma (PACG) is more blinding (1 in 4 cases) than primary open angle glaucoma (1 in 10 cases). Cataract surgery is an effective initial treatment for majority of cases of PACG. However, cataract surgery alone may not be enough to control intraocular pressure (IOP) in cases with extensive synechial angle closure glaucoma. It is reported that glaucoma drainage surgery is needed in 12% of PACG cases after cataract surgery. Some experts combine cataract surgery with either goniosynechialysis (GSL) or endocyclophotocoagulation (ECP) to enhance IOP control. However, neither combination ensures complete success. We report three subjects with extensive synechia! angle closure in whom we facilitated a technique that combines lens extraction with ECP and endoscopic-GSL (PIECES). We demonstrated that this combined technique was a more effective and efficient method of achieving lower IOP in the presence of extensive synechial PACG. We believe that it addresses both the inflow and outflow of the aqueous humor simultaneously. Two out of three patients had good IOP control without medication and one patient needed one drop after a minimum 12 months of follow up. Furthermore, it may reduce the need for medical therapy and future more invasive glaucoma drainage surgery. How to cite this article: Alaghband P, Rodrigues IAS, Goyal S.

Abstract
The primary angle-closure disease spectrum varies from a narrow angle to advanced glaucoma. A variety of imaging technologies may assist the clinician in determining the pathophysiology and diagnosis of primary angle closure, but gonioscopy remains a mainstay of clinical evaluation. Laser iridotomy effectively eliminates the pupillary block component of angle closure; however, studies show that, in many patients, the iridocorneal angle remains narrow from underlying anatomic issues, and increasing lens size often leads to further narrowing over time. Recent studies have further characterized the role of the lens in angle-closure disease, and cataract or clear lens extraction is increasingly used earlier in its management. As a first surgical step in angle-closure glaucoma, lens extraction alone often effectively controls the pressure with less risk of complications than concurrent or stand-alone glaucoma surgery, but may not be sufficient in more advanced or severe disease. We provide a comprehensive review on the primary angle-closure disease nomenclature, imaging, and current laser and surgical management.

Abstract
Abstract
Background:Cataract extraction surgery significantly decreases intraocular pressure (IOP) in patients with various forms of angle closure glaucoma (ACG). However, most reports did not specify the circumferential extent of peripheral anterior synechiae (PAS). Objective: Evaluate IOP after phacoemulsification with intraocular lens (IOL) implantation in chronic ACG patients without extensive PAS. Materials and methods: Data of chronic ACG patients with documented peripheral PAS <180 degrees and clinically significant cataract, who underwent phacoemulsification with IOL implantation at King Chulalongkorn Momorial Hospital between May 2002 and June 2007 were reviewed retrospectively. Baseline characteristics as gender, degree of PAS, IOP, and number of medications were collected. The outcomes were post-operative IOP at 6, 12, and 18 months, and number of hypotensive medications. Results: Twenty-five eyes from 25 patients (mean age: 73.0 years old) were included in this study. Twenty-three out of 25 patients were female, and 17 had PAS less than 90 degrees. Pre-operative mean IOP was 15.6 mmHg, while pre-operative median (Q1, Q3) number of hypotensive medications was 2 (1, 2). After operation, statistically significant lower IOPs were seen at all time points. Mean IOP at 6, 12, and 18 months were 12.4, 11.0, and 11.9 mmHg respectively. In addition, post-operative number of hypotensive medication was also statistically significantly less than baseline, with median (Q1, Q3) 1 (0, 1), and 20% of these eyes were medication-free. Conclusion: Phacoemulsification and IOL implantation surgery alone in chronic ACG patients without extensive PAS can significantly lower IOP up to 18 months postoperatively.

Abstract
PURPOSE To assess long-term changes in intraocular pressure (IOP) and the development of glaucoma after early phacoemulsification in acute primary angle closure. METHODS Retrospective chart review of acute primary angle closure patients treated with phacoemulsification in attack eyes versus fellow eyes. Within a month after the angle closure attack, all subjects underwent cataract surgery and were divided into two groups: group A received cataract surgery on their attack eyes. Group B also received cataract surgery on their fellow eye after phacoemulsification of the attack eyes. Study outcomes were the prevalence of IOP rise (occurrence of IOP >21 mmHg) and the incidence of newly developed glaucoma. RESULTS Eighty-nine eyes were included, with 62 attack eyes in group A and 27 fellow eyes in group B. Group A (14 eyes, 22.58%) had a higher cumulative rate of IOP rise than group B (3 eyes, 11.11%) at 12 months (p = 0.001). Newly developed glaucoma was not observed in group B; however, 6 patients in group A developed glaucoma during the 12-month follow-up period (p < 0.001). CONCLUSIONS The attack eyes treated with phacoemulsification showed a significantly higher prevalence of IOP rise and newly developed glaucoma than fellow eyes that received phacoemulsification. These findings suggest that there is a possibility of IOP rise and development of glaucoma even when angle closure and successful IOP control have apparently been achieved after phacoemulsification.
