Ophthalmol Glaucoma 2024; 7:206-215. [PMID: 37783274 DOI: 10.1016/j.ogla.2023.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Revised: 09/13/2023] [Accepted: 09/25/2023] [Indexed: 10/04/2023]
Abstract
PURPOSE To determine the clinical utility of OCT retinal nerve fiber layer (OCT RNFL) imaging for glaucoma evaluation in patients with Boston keratoprosthesis type 1 (KPro) by investigating imaging artifacts. DESIGN Case-control study. SUBJECTS Patients with KPro and without KPro (controls) matched for age, gender, and glaucoma diagnosis. METHODS The most recent Cirrus OCT RNFL scan from 1 eye was categorized as having good signal strength (SS; ≥ 6 out of 10) or poor SS (< 6). Those with good SS were analyzed by 2 independent reviewers for artifacts. Images with good SS and no artifacts affecting the scanning circle were considered useful for glaucoma evaluation. MAIN OUTCOME MEASURES The incidence of poor SS and artifacts in OCT RNFL images; patient characteristics associated with useful scans. RESULTS Sixty-five patients with KPro and 75 controls were included; 89.2% of KPro patients and 89.3% of control subjects had glaucoma (P = 0.98). Forty percent of KPro patients and 5.3% of controls had poor SS (P < 0.001). The proportion of images with either poor SS or artifacts was similar in KPro (76.9%) vs. controls (72.0%, P = 0.51). The most common artifacts in both groups were missing data (43.6%, 53.2%, respectively, P = 0.32) and motion artifact (25.6%, 19.7%, respectively, P = 0.47). Images were useful for glaucoma evaluation in 43.1% of KPro patients and in 69.3% of controls (P = 0.002). In the KPro group, patients with useful OCT scans, compared with those without, had better visual acuity (0.4 ± 0.3 vs. 0.9 ± 0.7 logarithm of the minimum angle of resolution, P = 0.004), and did not have congenital corneal pathologies (0.0% vs. 24.3%, P = 0.008). A multivariate analysis showed that KPro patients with older age had higher odds of useful OCT images (odds ratio, 1.05; P = 0.03). Among KPro patients with useful OCT scans, retinal nerve fiber layer thickness correlated with observed cup-to-disc ratio (Pearson correlation: r = -0.42, P = 0.03). CONCLUSIONS The rate of OCT RNFL images with either poor signal strength or artifacts in the KPro and control population was comparable. In patients with KPro, where intraocular pressure measurements are difficult and glaucoma is highly prevalent and often severe, OCT RNFL imaging can be useful for glaucoma evaluation.

Abstract
The anterior segment dysgeneses are a broad group of heterogeneous disorders characterized by developmental abnormalities of the anterior segment of the eye, including primary congenital aphakia, Peters sequence, aniridia, and Axenfeld-Rieger spectrum. These conditions can have overlapping phenotypes and both genotypic and phenotypic heterogeneity. This article provides a strategy for both phenotyping and then genotyping using a targeted stepwise approach.

Incidence and risk factors for glaucoma development and progression after corneal transplantation. Eye (Lond) 2023; 37:2117-2125. [PMID: 36329167 PMCID: PMC10333209 DOI: 10.1038/s41433-022-02299-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 10/03/2022] [Accepted: 10/18/2022] [Indexed: 11/06/2022] Open
Abstract
OBJECTIVE To assess the cumulative incidence and risk factors for glaucoma development and progression within 1-2 years following corneal transplant surgery. DESIGN Retrospective cohort study. METHODS Patients undergoing penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK), Descemet stripping endothelial keratoplasty (DSEK), Descemet membrane endothelial keratoplasty (DMEK), Boston keratoprosthesis type I (KPro) implantation, or endothelial keratoplasty (DSEK or DMEK) under previous PK (EK under previous PK) at one academic institution with at least 1 year of follow-up were included. Primary outcome measures were cumulative incidence of glaucoma development and progression after corneal transplant, in patients without and with preoperative glaucoma, respectively. Risk factors for glaucoma development and progression were also assessed. RESULTS Four hundred and thirty-one eyes of 431 patients undergoing PK (113), DALK (17), DSEK (71), DMEK (168), KPro (35) and EK under previous PK (27) with a mean follow-up of 22.9 months were analyzed. The 1-year cumulative incidence for glaucoma development and progression was 28.0% and 17.8% in patients without and with preoperative glaucoma, respectively. In a Cox proportional hazards analysis, DSEK surgery, KPro implantation, average intraocular pressure (IOP) through follow-up and postoperative IOP spikes of ≥30 mmHg were each independently associated with glaucoma development or progression (p < 0.04 for all). CONCLUSIONS A significant proportion of patients developed glaucoma or exhibited glaucoma progression within 1 year after corneal transplantation. Patient selection for DSEK may partly explain the higher risk for glaucoma in these patients. Postoperative IOP spikes should be minimized and may indicate the need for co-management with a glaucoma specialist.

Abstract
Background Evaluate outcomes and identify prognostic factors in congenital aniridia. Methods Retrospective interventional case series of patients with congenital aniridia treated between 2012–2020. Ocular examination and surgical details were collected. Surgical failure was defined as disease progression or need for additional surgery for same/related indication. Kaplan–Meier survival curves, Wilcoxon test, and univariate and multivariate linear regression analyses were performed. Results Ninety-four patients with congenital aniridia presented at median 19.0 years. Two-thirds of patients underwent ≥ 1intraocular surgery, with average of 1.7 ± 2.3 surgeries/eye. At final follow-up (median 4.0 years), 45% of eyes had undergone lensectomy. Aphakic eyes showed worse visual acuity (VA) than phakic or pseudophakic eyes. Glaucoma affected 52% of eyes, of which half required IOP-lowering surgery. Glaucoma drainage devices showed the highest success rate (71%) at 14.2 ± 15.4 years of follow-up. Keratopathy affected 65% of eyes and one-third underwent corneal surgery. Keratoprosthesis had the longest survival rates at 10-years (64% with 95% CI [32,84]). LogMAR VA at presentation and final follow-up were not statistically different. Half of patients were legally blind at final follow-up. Final VA was associated with presenting VA, glaucoma diagnosis, and cataract or keratopathy at presentation. Penetrating keratoplasty and keratoprosthesis implantation correlated with worse BCVA. Conclusions Most aniridic patients in this large US-based cohort underwent at least 1 intraocular surgery. Cataract, glaucoma, and keratopathy were associated with worse VA and are important prognostic factors to consider when managing congenital aniridia.

Abstract
PURPOSE To determine the role and optimal timing of glaucoma surgery in relation to Boston keratoprosthesis type 1 (KPro) implantation. DESIGN Retrospective, comparative, nonrandomized clinical study. METHODS Single-center study of a total of 100 eyes (100 patients) implanted with a KPro between 2008 and 2017, and diagnosed with glaucoma before or after KPro. Patients were separated into 2 groups: those with preexisting glaucoma and those who developed de novo glaucoma after KPro. Groups were then divided based on whether patients were medically or surgically managed. Glaucoma surgery included glaucoma drainage device (GDD) implantation, trabeculectomy, and cyclophotocoagulation (CPC). Primary outcomes included best-corrected visual acuity (BCVA), glaucoma progression, and complications. Differences in outcomes were compared using parametric and nonparametric tests, as well as log-rank test to compare time-to-outcome events. RESULTS Among 72 eyes with preexisting glaucoma, 27 (38%) had glaucoma surgery before KPro (18 GDD), whereas 45 (62%) were medically managed only. Among the latter, 19 (42%) needed glaucoma surgery post-KPro (16 GDD). Among 28 eyes with de novo glaucoma, 12 (43%) had glaucoma surgery post-KPro (9 GDD). For eyes with preexisting glaucoma, glaucoma progression was greater with glaucoma surgery performed post-KPro (100%) compared with pre-KPro (74%, P = .016) and to medical management (54%, P = .002). No increase in complications were observed with glaucoma surgery compared to medications only (P > .05), whereas fewer eyes maintained a BCVA of 20/200 or better over time with medical management (P = .013). Eyes with de novo glaucoma had similar progression, BCVA, and complications between medical and surgical care (P > .05). CONCLUSIONS Glaucoma surgery should be performed before or at the same time as KPro implantation in eyes with preexisting glaucoma. Complication rates are not increased when glaucoma surgery is performed in KPro eyes with either preexisting or de novo glaucoma. To ensure optimal glaucoma control, glaucoma surgery should be performed as early as possible in KPro eyes with good visual potential.

Abstract
Introduction To compare outcomes in eyes with ocular burns following Boston Type I keratoprosthesis (KPro) implantation with and without prophylactic pars plana tube surgery. Methods A retrospective review of patients with ocular burns who underwent KPro surgery at Zhongshan Ophthalmic Center was performed. Twenty-six eyes of 26 patients without a preoperative diagnosis of glaucoma before KPro surgery met the inclusion criteria. Preoperative glaucoma was defined as a history of a durable elevated intraocular pressure (IOP) ≥ 25 mmHg at different time points, which resulted in the introduction of anti-glaucoma medication or surgical intervention. Sixteen eyes underwent KPro alone (Group 1), and 10 eyes received KPro with prophylactic pars plana tube surgery (Group 2). Results Group 1 and Group 2 were similar in the proportions of the ocular burn type and preoperative clock hours of peripheral anterior synechiae by ultrasound biomicroscopy (1.88 ± 1.63 vs. 2.30 ± 1.83; P = 0.54). Before KPro surgery, 62.5% of eyes in Group 1 and 50.0% of eyes in Group 2 had intraocular surgeries (P = 0.53). The follow-up time was 18 months. At the final follow-up time, the two groups had similar visual acuity (1.34 ± 0.87 logMAR, 1.03 ± 0.71 logMAR; P = 0.35) and eyes with a C/D ratio ≥ 0.8 (7/16, 2/10; P = 0.21), but more eyes in Group 1 developed glaucoma de novo than eyes in Group 2 (62.5%, 20%; P = 0.04) and had undergone secondary glaucoma surgery after KPro implantation (7/16 vs. 0/10; P = 0.02). Conclusion In eyes injured with ocular burns, KPro implantation with prophylactic pars plana tube surgery may be a feasible option to rehabilitate visual acuity and decrease the incidence of glaucoma de novo.

Abstract
Congenital aniridia is a multisystemic genetic disease due to a mutation in PAX6 gene which severely affects the development and functionality of the human eyes. In patients affected by the mutation, aside from the absence or defects of iris tissue formation, abnormalities in position or opacities of the crystalline lens, macular hypoplasia, ocular surface disease is the main cause of visual loss and the deterioration of the quality of life of most patients. Limbal stem cell deficiency combined with tear film instability and secondary dry eye cause aniridic keratopathy which, in advanced stages, ends up in corneal opacification. In this paper, the actual knowledge about congenital aniridia keratopathy physiopathology and medical and surgical treatment options and their efficacy are discussed. Indications and results of topical treatments with artificial tears and blood-derivatives in its initial stages, and different surgical techniques as limbal stem cell transplantation, keratoplasty and keratoprostheses are reviewed. Finally, recent advances and results in regenerative medicine techniques with ex vivo stem cell cultivation or other types of cultivated cells are presented.

Abstract
Aniridia is a congenital bilateral ocular disorder with dominant autosomal inheritance. More than 50% of patients will develop aniridic glaucoma (AG) during their lives. Open angle glaucoma is more common in aniridia, but a closed angle mechanism has been described in relation with anterior rotation of the rudimentary iris, occluding trabecular meshwork. Diagnosis and follow-up of AG is difficult in relation with the presence of keratopathy, nystagmus and foveal hypoplasia. Central corneal thickness usually measures more than 600 microns, which prevents achieving a reliable value of intraocular pressure. Medical treatment of AG is no different from the rest of glaucoma. It is recommended to use preservative free formulations, and combined therapy is often required. Surgical treatment is needed in many cases. There is no consensus on the first line surgery for AG, but in open angle AG, angle surgery is usually first choice, and glaucoma drainage devices are the next preferred surgical technique. In closed angle AG glaucoma drainage devices are usually the first choice, with trabeculectomy as the second preferred surgical technique.

Abstract
PURPOSE To study the long-term intraocular pressure (IOP) and visual outcomes in treated aniridic glaucoma. METHODS A retrospective chart review of patients with aniridia and glaucoma, with ≥ 2-year follow-up, was performed. Eyes in early glaucomatous stages were medically managed, while moderate-severe stage eyes underwent a trabeculectomy with mitomycin-c (MMC). Success was termed 'complete' when average final IOP was ≤ 18 mmHg without usage of glaucoma medications, and 'qualified' when with/without topical glaucoma therapy. A significant change in vision was defined as > 2-line change on Snellen vision chart or > 0.2 change in logMAR units in in either direction (better or worse). RESULTS Thirty-five eyes of 20 patients were included. The mean duration of follow-up was 7.29 ± 5.75 years. Associated ocular anomalies were present in 19 eyes (54.29%). Twelve eyes (34.28%) were maintained on medical management, while 23 eyes (65.71%) had undergone a trabeculectomy with MMC. The mean baseline IOP was 31.46 ± 6.34 mmHg, and mean IOP on last follow-up was 13.25 ± 5.82 mmHg, p < 0.001. Seventy-five percent of the medically managed eyes achieved an IOP ≤ 18 mmHg. 52.17% and 95.65% of the surgically treated eyes achieved 'complete' and 'qualified' success respectively. The median best corrected visual acuity (BCVA) at baseline was 1.48(0.6-2) logMAR units and on final follow-up was 1.3 (0.48-5) logMAR units, p = 0.21. Fifty percent of the eyes remained stable, 35.71% showed an improvement and 14.29% a deterioration of > 0.2 logMAR units. Patients with a longer follow-up (> 10 years) and those who had undergone a trabeculectomy with MMC were more likely to show good IOP control (p = 0.003; p = 0.004 respectively). CONCLUSION Aniridic glaucoma can be managed efficiently by medications in early glaucomatous neuropathy, and with trabeculectomy augmented with mitomycin-C and releasable sutures for more advanced glaucomas, offering favourable long-term IOP control, visual stability and safety.

Geoffrion D, Harissi-Dagher M. Glaucoma Risk Factors and Outcomes Following Boston Keratoprosthesis Type 1 Surgery. Am J Ophthalmol 2021; 226:56-67. [PMID: 33493469 DOI: 10.1016/j.ajo.2021.01.006] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 01/04/2021] [Accepted: 01/06/2021] [Indexed: 01/25/2023]
Abstract
PURPOSE To evaluate glaucoma risk factors and associated outcomes of the Boston keratoprosthesis type I (KPro). DESIGN Clinical case-control study. METHODS This is a single-center study of 140 eyes of 118 patients who underwent KPro surgery between October 2008 and March 2017 by a single surgeon. A total of 118 eyes of 118 patients with at least 6 months of follow-up were analyzed to account for intereye correlation. Patients without glaucoma were compared to those diagnosed with glaucoma, which included treatment with intraocular pressure (IOP)-lowering medications or glaucoma surgery. A subgroup analysis compared eyes with pre-KPro glaucoma with those with post-KPro glaucoma. Statistical analysis was performed using univariate and multivariate analyses and Kaplan-Meier survival curves. Main outcome measures were glaucoma diagnosis and progression. Other outcomes included demographics, preoperative diagnosis, best-corrected visual acuity, IOP, cup-to-disc ratio progression and postoperative complications. RESULTS The mean age at surgery was 60.7 ± 16.7 years, with a follow-up of 6.9 ± 3.2 years. De novo KPro glaucoma incidence was 24% (n = 28/118), equivalent to 3.4 cases per 100 eye-years, with onset at 2.1 ± 2.2 postoperative years. A total of 17 of 118 eyes (14%) did not have glaucoma. Multiple logistic regression showed that high preoperative IOP was a predictor of higher rates of glaucoma development (odds ratio [OR] = 1.538, 95% confidence interval [CI] = 1.030-2.297, P = .035) and progression (OR = 1.450, 95% CI = 1.084-1.937, P = .012). Stromal and endothelial disorders were protective preoperative diagnoses for glaucoma progression after KPro (OR = 0.002, 95% CI = 0.000-0.227, P = .010). A greater proportion of eyes with autoimmune and ocular surface diseases developed de novo glaucoma after KPro compared with other preoperative diagnoses (P < .05). A total of 45% of glaucomatous KPro eyes suffered postoperative glaucoma progression. The mean final best-corrected visual acuity of the cohort was 1.76 ± 1.0, with no difference between eyes with and without glaucoma (P > .05). The rate of serious vision-threatening complications was higher in KPro eyes without glaucoma (77%) than in those with glaucoma (41%, P = .006). CONCLUSIONS High preoperative IOP signals a higher risk for glaucoma development and progression after KPro surgery. Autoimmune diseases and ocular surface diseases precipitate de novo glaucoma, whereas stromal and endothelial disorders protect against glaucoma progression after KPro. The minority of KPro eyes without glaucoma remain at high risk of complications that can hinder promising visual outcomes. Despite all available treatments and surgical interventions, a majority of eyes will suffer from glaucoma progression, even later during follow-up.

Abstract
Purpose Inflammatory cytokines are involved in glaucoma pathogenesis. The purpose is to compare cytokine levels in the tear film of Boston keratoprosthesis (KPro) patients with and without glaucoma, relative to controls, and correlate levels with clinical parameters. Methods This cross-sectional study enrolled 58 eyes (58 patients): 41 KPro eyes with glaucoma, 7 KPro eyes without glaucoma, and 10 healthy controls. Twenty-seven cytokines were measured by multiplex bead immunoassay. Intraocular pressure (IOP), cup-to-disk ratio (CDR), retinal nerve fiber layer, visual acuity, topical medications, and angle closure were assessed in all KPro eyes. Cytokine levels between groups were analyzed by nonparametric tests, and correlations with clinical parameters by Spearman's test. Results Levels of TNF-ɑ, IL-1β, FGF-basic, and IFN-ɣ were significantly higher in KPro with glaucoma compared to KPro without (P = 0.020; 0.008; 0.043; 0.018, respectively). KPro groups had similar characteristics and topical antibiotic/steroid regimen. Levels of IL-1Ra, IL-15, VEGF, and RANTES were significantly higher in KPro with glaucoma compared to controls (P < 0.001; = 0.034; < 0.001; = 0.001, respectively). IL-1β and IFN-ɣ levels were positively correlated with CDR (r = 0.309, P = 0.039 and r = 0.452, P = 0.006, respectively) and IOP (r = 0.292, P = 0.047 and r = 0.368, P = 0.023, respectively). TNF-α and FGF-basic levels were positively correlated with CDR (r = 0.348, P = 0.022 and r = 0.344, P = 0.021, respectively). Conclusions TNF-α, IL-1β, FGF-basic, IFN-ɣ are elevated in tears of KPro patients with glaucoma and correlate with CDR and IOP. These results show, for the first time in humans, concordance with documented elevations of TNF-α and IL-1β in the murine KPro model. Ocular surface inflammation may reflect inflammatory processes of KPro glaucoma.

Abstract
Aniridia is a congenital bilateral ocular disorder with dominant autosomal inheritance. More than 50% of patients will develop aniridic glaucoma (AG) during their lives. Open angle glaucoma is more common in aniridia, but a closed angle mechanism has been described in relation with anterior rotation of the rudimentary iris, occluding trabecular meshwork. Diagnosis and follow-up of AG is difficult in relation with the presence of keratopathy, nystagmus and foveal hypoplasia. Central corneal thickness usually measures more than 600 microns, which prevents achieving a reliable value of intraocular pressure. Medical treatment of AG is not different from the rest of glaucoma. It is recommended to use preservative free formulations, and combined therapy is often required. Surgical treatment is needed in many cases. There is no consensus on the first line surgery for AG, but in open angle AG, angle surgery is usually first choice, and glaucoma drainage devices are the next preferred surgical technique. In closed angle AG glaucoma drainage devices are usually the first choice, with trabeculectomy as the second preferred surgical technique.

Treatment of Oculoplastic and Ocular Surface Disease in Eyes Implanted with a Type I Boston Keratoprosthesis in Southern China: A Retrospective Study. Adv Ther 2020; 37:3206-3222. [PMID: 32436025 DOI: 10.1007/s12325-020-01381-3] [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: 03/27/2020] [Indexed: 12/12/2022]
Abstract
INTRODUCTION This study aimed to describe the clinical features, surgical management of the eyelid and ocular surface, and outcomes of 16 patients implanted with a Boston type I keratoprosthesis (KPro). METHODS A retrospective, single-center, consecutive case series of 16 patients with Stevens-Johnson syndrome (1), ocular chemical burns (12), and ocular thermal burns (3) implanted with KPro was studied. All subjects were men aged 27-51 years. Surgical treatment and outcomes for eyelid malposition, symblepharon, and glaucoma were assessed. RESULTS From September 2010 to February 2019, 29 patients were admitted to Zhongshan Ophthalmic Center for KPro implantation, of whom 16 (55%) required eyelid or ocular surface surgeries to maintain hydration and protect the corneal tissue, which is vulnerable to epithelial defects. Forty-one adnexal surgical procedures were performed. The most common indication for surgery was symblepharon, and the most frequent procedures were symblepharon lysis with ocular mucous membrane grafts and amniotic membranes (7) and full-thickness skin grafts to the eyelids (7). Preoperative conjunctival injection and corneal staining were documented in 9 (56%) and 8 (50%) eyes, respectively, and at up to 4 months postoperative follow-up (the last adnexal surgery before KPro) were recorded in 3 (19%, p = 0.03) and 2 (12%, p = 0.02) eyes, respectively. Glaucoma drainage devices were inserted in six patients. One patient with Stevens-Johnson syndrome underwent FP7 Ahmed glaucoma valve (AGV) implantation inferotemporally and developed plate exposure 2 months postoperatively. Five patients underwent FP8 AGV implantation with tube insertion into the vitreous cavity due to the scarred conjunctiva and limited subconjunctival space. In the study period, intraocular pressure (IOP) was in the normal range, and no tube or plate exposure was observed. CONCLUSION The ocular environment is critical for successful KPro surgery. A multidisciplinary approach for any lid and ocular surface abnormality in ocular burns or Stevens-Johnson syndrome is important to improve the quality of the ocular surface and accommodate KPro and AGV, which is vital for maintaining vision after KPro surgery. FP8 AGV may be feasible for IOP control in adult KPro cases with restricted subconjunctival space.
