Abstract
PURPOSE To conduct a review of glaucoma management in France. METHOD A 15-question survey was sent to ophthalmologists listed in the journal Réalités Ophtalmologiques and the Syndicat National des Ophtalmologues de France. RESULTS 459/471 responses were analyzed. Gonioscopy was performed by 64.7% of respondents with a Goldmann three-mirror lens, by 51.4% with a four-mirror lens, and 8.2% preferred to perform the procedure with anterior segment imaging. The visual field was reported to be interpreted without difficulty by 87.8% of the practitioners, and 54.0% utilize a progression software. Ultrasound biomicroscopy was reported to be interpreted without difficulty by 20.0% of practitioners. In cases of severe ocular hypertonia with flat bleb in early postoperative trabeculectomy, 61.7% chose ocular massage as a first-line treatment, 52.9% chose laser suture lysis, 50.5% utilized needling, and 24.8% employed hypotonizing eyedrops. In case of severe ocular hypertonia with flat bleb in early postoperative deep sclerectomy, 53.2% chose goniopuncture as their first treatment, 34.4% employed needling, 31.8% utilized ocular massage, and 23.3% chose hypotonizing eyedrops. The selective laser trabeculoplasty is used as soon as the diagnosis is made by 37.5%, in association with a mono or dual therapy by 93.2%, after trying different combinations of eyedrops by 45.5%, when the visual field deteriorates despite a normalized intraocular pressure by 46.6%, and in cases of hypertonia after filtering surgery by 19.2%. Concerning management for primary angle-closure glaucoma, 80.8% considered peripheral iridotomy, and 18.7% utilized cataract surgery. CONCLUSION The diversity of responses concerning glaucoma management should draw attention to the need for standardized practices.

Abstract
Purpose To evaluate the role of automated peripheral iridectomy as an adjunctive tool combined with phacoemulsification and ExPRESS shunt implantation in management of cases with chronic angle closure glaucoma. Setting Magrabi eye hospital. Methods This prospective study included 22 eyes of 22 patients with chronic angle closure glaucoma and cataract who underwent Ex-PRESS shunt implantation, cataract extraction and surgical peripheral iridectomy at the site of shunt implantation in the period between January 2018 and April 2020. Results After surgery, the mean IOP was 11.3±1.2 mm Hg, 14.5±1.6 mm Hg, 14.8±2.1 mm Hg, 15.3±1.9 mm Hg and 17.4±1.8 mm Hg at 7 days, 1 month, 3 months, 6 months and 12 months, respectively. All postoperative IOP was significantly lower compared with preoperative IOP (P = 0.001). There was a significant decrease in the number of medications required after surgery. The baseline mean number of medications was 3.4±0.02 (range from 1 to 4), while postoperatively the mean number of medications decreased to 0.7±0.01 at 12 months (P < 0.01). The qualified success rate was 6/22 eyes, and the complete success rate was 16/22 (72.7%) at 12 months, respectively. Conclusion The combined phacoemulsification and Ex-PRESS shunt implantation with automated peripheral iridectomy is an effective and safe procedure to treat chronic angle closure 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.

Ultrasound Biomicroscopy Might Predict the Outcome of Phacoemulsification-Visco Dissection in Medically Controlled Primary Angle-Closure Glaucoma Eye With Extensive Peripheral Anterior Synechia. Front Med (Lausanne) 2021; 8:705864. [PMID: 34350200 PMCID: PMC8326522 DOI: 10.3389/fmed.2021.705864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 06/16/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: The treatment procedures of primary angle-closure glaucoma (PACG) with extensive peripheral anterior synechia (PAS) is a subject of debate. This study is to investigate the clinical features of phacoemulsification (Phaco)-visco dissection in medically controlled PACG patients with PAS > 180° and evaluate the predictability of Ultrasound Biomicroscopy (UBM) parameters on postoperative intraocular pressure (IOP). Methods: 48 eyes (48 patients) with acute angle-closure glaucoma (AACG) and 30 eyes (30 patients) with chronic angle-closure glaucoma (CACG) were prospectively included. All patients underwent phaco-viscogoniolysis and foldable lens implantation and were followed for 1 year after surgery. We analyzed preoperative and postoperative IOP, the numbers of anti-glaucoma medicine, the visual field value, the extent of PAS, and UBM parameters alterations, and evaluated the correlation between preoperative UBM parameters and one-year postoperative IOP. Results: IOP reduced significantly from 16.24 ± 4.33 to 14.49 ± 3.69 mmHg in AACG group and from 16.16 ± 3.69 mmHg to 14.31 ± 4.12 mmHg in CACG group, and PAS decreased significantly from 270 ± 60.33 to 171 ± 56.44° in AACG group and from 285 ± 70.46 to 168 ± 61.32° in CACG group, and the number of anti-glaucoma drugs decreased significantly in both groups. Several UBM parameters, including anterior chamber depth, trabecular iris angle, and peripheral iris thickness 500 increased while iris convex reduced considerably in the two groups, and angle opening distance 500 and trabecular-meshwork ciliary process angle increased significantly only in AACG group. One-year postoperative IOP correlated with preoperative angle opening distance 500 and trabecular iris angle negatively and iris convex positively. Conclusion: Phaco-visco dissection can effectively reduce IOP, the numbers of glaucomatous medications, and PAS in medically controlled PACG patients with extensive PAS. UBM parameters might be valuable for analyzing postoperative anterior segment structure and predicting postoperative IOP of Phaco-visco dissection in PACG patients with extensive PAS.

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 feasibility, efficacy, and safety of Ex-PRESS implantation combined with phacoemulsification surgery in primary angle-closure glaucoma (PACG) with cataract. MATERIALS AND METHODS This is a prospective, nonrandomized study. A total of 34 eyes of 34 subjects were enrolled. The assessments were conducted preoperatively and postoperatively at 1 week and 1, 3, 6, 12, 18, 24, 30, and 36 months. The assessments included intraocular pressure (IOP), best-corrected visual acuity (BCVA), the number of glaucoma medications, corneal endothelial cell density (ECD), and related complications, if any. The anterior segment structure was also assessed by anterior segment optical coherence tomography based on the anterior chamber depth (ACD), angle opening distance (AOD500), and trabecular-iris angle (TIA). A complete success was defined as a controlled IOP between 5 and 21 mmHg without medications. RESULTS The complete success rates at 12, 24, and 36 postoperative months were 91.2%, 81.7%, and 78.3%, respectively. The mean preoperative IOP was 28.43 ± 12.93 mmHg and decreased to 15.35 ± 4.02 mmHg at 3 years postoperatively (P < 0.001). The number of medications decreased from 2.47 ± 1.89 at baseline to 0.28 ± 0.76 at 3 years postoperatively (P = 0.001). BCVA was 0.83 ± 0.58 at baseline and 0.51 ± 0.33 at 3 years postoperatively (P = 0.008). The ACD, AOD500, and TIA significantly increased at 3 months postoperatively compared with baseline (P < 0.001). ECD at 3 months and 3 years postoperatively were both significantly lower compared with baseline (P = 0.03), but was not significantly different between 3 months and 3 years postoperatively (P = 0.07). The device-related complications identified were hypotony (5.8%), hyphema (2.9%), and iris touch (2.9%), which the incidence rates were all very low. CONCLUSIONS Ex-PRESS implantation combined with phacoemulsification was effective for lowering IOP in PACG coexisting with cataract. The device-related complication was rare.

Abstract
Ophthalmic ultrasound is an invaluable tool that provides quick and noninvasive evaluation of the eye and the orbit. It not only allows the clinicians to view structures that may not be visible with routine ophthalmic equipment or neuroimaging techniques but also provides unique diagnostic information in various ophthalmic conditions. In this article, the basic principles of ophthalmic ultrasound and examination techniques are discussed. Its clinical application is illustrated through a variety of ocular pathologic abnormalities (eg, narrow angles, ciliary body tumor, detached retina, choroidal melanoma, and papilledema).

Abstract
Primary angle-closure glaucoma (PACG) is a progressive optic nerve degeneration and is defined as a glaucomatous optic neuropathy with associated characteristic enlargement of optic disc cupping and visual field loss that is secondary to ocular hypertension caused by closure of the drainage angle. Angle closure is caused by appositional approximation or adhesion between the iris and the trabecular meshwork. The main treatment strategy for PACG lies in the reduction of intraocular pressure, reopening of the closed angle, and possible prevention of further angle closure. There is no universally agreed best surgical treatment for PACG. Trabeculectomy, goniosynechialysis (GSL), glaucoma implant, and cyclodestructive procedures are effective surgical options. Each of them plays an important role in the management of PACG with its own pros and cons. Accumulating evidence is available to show the effectiveness of visually significant and visually nonsignificant cataract extraction in the treatment of PACG. Trabeculectomy and GSL are often combined with cataract extraction, which may offer additional pressure control benefits to patients with PACG. This review article will discuss laser peripheral iridotomy, argon laser peripheral iridoplasty, and surgeries such as GSL, phacoemulsification, and phaco plus glaucoma surgeries that lower intraocular pressure and also alter the anterior segment and/or drainage angle anatomy. Currently, glaucoma implants and cyclodestruction are mainly reserved for PACG patients who have failed previous filtering operations. Their role as initial surgical treatment for PACG will not be discussed.

Abstract
AIM To evaluate the difference in angle parameters and clinical outcome following phacoemulsification and combined phacotrabeculectomy in patients with acute primary angle closure (APAC) using ultrasound biomicroscopy (UBM). METHODS Patients (n=23, 31 eyes) were randomized to receive phacoemulsification or combined phacotrabeculectomy (n=24, 31 eyes). Best-corrected visual acuity (BCVA), intraocular pressure (IOP), the main complications following surgery, and indentation gonioscopy and angle parameters measured using UBM were documented preoperatively and postoperatively. RESULTS The improvement in BCVA in the phacoemulsification group was significantly greater than in the combined group (P<0.05). IOP in the phacoemulsification group was slightly higher than in the combined group following 1wk of follow-up (P<0.05), whereas there was no significant difference between the two groups at the latter follow-up (P>0.05). Phacoemulsification alone resulted in a slight increase in the trabecular ciliary processes distance compared with the combined surgery (P<0.05), whereas the other angle parameters showed no significant difference between the groups. Complications in combined group were greater than phacoemulsification only group. CONCLUSION Both surgeries effectively opened the drainage angle and deepened the anterior chamber, and IOP was well controlled postoperatively. However, phacoemulsification showed better efficacy in improving visual function and showed reduced complications following surgery.

Abstract
Optical coherence tomography (OCT) is a cross-sectional, three-dimensional, high-resolution imaging modality that uses low coherence interferometry to achieve axial resolution in the range of 3-20 μm. Two OCT platforms have been developed: time domain (TD-OCT) and spectral (or Fourier) domain (SD/FD-OCT). Visante anterior segment OCT (Carl Zeiss Meditec) is a TD-OCT widely used for anterior segment imaging. The SD-OCT systems with both posterior and anterior segment imaging capabilities include the RTVue, iVue (Optovue), the Cirrus (Carl Zeiss Meditec), and the Spectralis (Heidelberg Engineering, Inc.). Each of the SD-OCTs has a wavelength in the range of 820-879 nm. Anterior segment OCT is a non-contact method providing high resolution tomographic cross-sectional imaging of anterior segment structures. Anterior segment OCT provides qualitative and quantitative assessment of the anterior segment structures important to the pathogenesis and the anatomical variations of glaucoma, and the approach to and success of treatment. We summarize the clinical applications of anterior segment OCT in glaucoma.
