Axenfeld–Rieger syndrome (ARS) is a rare disease characterized by anterior segment anomalies with or without glaucoma. A 28-year-old antenatal female diagnosed with ARS presented with uncontrolled intraocular pressures (IOPs) and advanced glaucoma despite maximal medical therapy and progressive vision loss during her third trimester. The refractory and progressive nature of the disease, with useful vision in one eye, necessitated immediate surgical intervention, following which there was successful control of IOP, lasting till the final follow-up at 18 months. We discuss the role of glaucoma surgery, for an ARS patient with refractory glaucoma during the third trimester with a comprehensive review of literature.

Purpose: To compare the surgical outcomes of trabeculectomy with and without anti-metabolites in patients with juvenile open-angle glaucoma (JOAG). Methods: This retrospective comparative case series included 98 eyes of 66 patients with JOAG who underwent either trabeculectomy without anti-metabolites (group A, n = 53 eyes) or with anti-metabolites (group B, n = 45 eyes) with a minimum of 2 years follow-up. The main outcome measures were intra-ocular pressure (IOP), number of glaucoma medications, visual acuity, additional surgical interventions, surgical complications, and risk factors for failure. Surgical failure was defined as IOP >18 mmHg or failure to reduce IOP by

In 2020, the global prevalence of glaucoma was estimated to be 76 million and it was projected to increase to 111.8 million by 2040. Accurate intraocular pressure (IOP) measurement is imperative in glaucoma management since it is the only modifiable risk factor. Numerous studies have compared the reliability of IOP measured using transpalpebral tonometers and Goldmann applanation tonometry (GAT). This systematic review and meta-analysis aims to update the existing literature with a reliability and agreement comparison of transpalpebral tonometers against the gold standard GAT for IOP measurement among individuals presenting for ophthalmic examinations. The data collection will be performed using a predefined search strategy through electronic databases. Prospective methods-comparison studies published between January 2000 and September 2022 will be included. Studies will be deemed eligible if they report empirical findings on the agreement between transpalpebral tonometry and Goldmann applanation tonometry. The standard deviation and limits of agreement between each study and their pooled estimate along with weights and percentage of error will be reported using a forest plot. Cochrane's Q test and the I2 statistic will be used to assess heterogeneity, and the publication bias will be investigated using a funnel plot, Begg's and Egger's tests. The review results will provide additional evidence on the reliability of transpalpebral tonometers that, in turn, could possibly assist practitioners to make informed decision about using it as a screening or diagnostic device for clinical practice, outreach camps, or home-based screening.

Escitalopram, a selective serotonin reuptake inhibitor is widely used for the treatment of depression in psychiatric and primary care practices. We report a rare instance of escitalopram-induced bilateral secondary angle closure and acute onset myopic shift in a young male treated for depression. Ultrasound biomicroscopy obtained after the onset of his symptoms revealed bilateral ciliochoroidal effusion. His signs and symptoms stabilized completely within two weeks of stopping the drug. The presentation of escitalopram-induced idiosyncratic reaction with bilateral angle closure and ciliochoroidal effusion was rarely reported in Indian ethnic eyes. A detailed history taking and meticulous clinical evaluation helped us differentiate from acute primary angle closure glaucoma.

Purpose: To correlate and analyze the pattern of the visual field (VF) defects by perimetry and anterior chamber angle parameters by AS-OCT in primary angle-closure glaucoma (PACG) across varied severity levels on presentation to a tertiary eye care center. Methods: This was a cross-sectional study, which included 323 eyes of clinically diagnosed cases of PACG. Glaucoma severity was categorized according to mean deviation (MD) as mild (-6.00 dB or more), moderate (-6.01 to -12.00 dB), and severe (-12.01 to -30.00 dB). AS-OCT measured the nasal (N) and temporal (T) angle opening distance at 500 μm (AOD 500) and 750 μm (AOD 750), anterior chamber angle (ACA), lens vault (LV), and anterior chamber width (ACW). The VF severity was then correlated with the AS-OCT parameters using statistical analysis. Results: The mean age ± standard deviation (SD) of the patients included in the study was 56.03 ± 8.6 years, with a 1:1.2 gender ratio. The number of eyes with mild, moderate, and severe VFs were 140 (43.3%), 88 (27.24%), and 95 (29.41%), respectively. There was no statistically significant correlation in the mean anterior chamber angle parameters (AOD 500, AOD 750, ACA 500, ACA 750, LV, ACW, and axial length (AL)) among the groups. However, the correlation between AOD 500 and LV thickness was found to be significant (P = 0.0000) with a negative Spearman's rank correlation coefficient (r = -0.3329). Conclusion: The ACA parameters obtained by AS-OCT along the horizontal axis after elimination of pupillary block by laser peripheral iridotomy do not correlate and cannot be used to assess the disease severity of PACG.

Purpose: To analyze the ocular biometric parameters of eyes with acute primary angle closure (APAC) as compared to fellow eyes. Methods: A cross-sectional study was conducted on 27 patients presenting with recent onset APAC to a tertiary eye institute in India. Anterior and posterior ocular biometric parameters were measured simultaneously by anterior segment optical coherence tomography (AS-OCT), A-scan, ultrasound biomicroscopy (UBM), and B-mode ultrasonogram (USG). The parameters measured were anterior chamber depth (ACD), anterior chamber angle (ACA), angle opening distance (AOD500, AOD750), lens vault (LV), axial length (AL), ciliary body thickness maximum (CBTmax) and at the point of scleral spur (CBT0), anterior placement of the ciliary body (APCB), and retinochoroidal thickness (RCS). Results: Mean age ± SD of patients with APAC was 55.66 ± 7.2 years with female preponderance (21:6 patients). Mean presenting IOP ± SD of the affected eye and fellow eye were 54.74 ± 11.67 mm Hg and 18.7 ± 11.67 mm Hg, respectively. Eyes with APAC had statistically significant narrower anterior ocular biometric parameters, higher LV, decreased ciliary body thickness, more APCB, and longer AL than the fellow eyes. CBTmax is the only variable that had significance (β = −0.421,95% CI: −0.806 to − 0.035, P = 0.034) in the univariate analysis with RCS thickness in APAC eyes. Further, there was a correlation between CBT0 and APCB with CBTmax both in univariate (β = 0.894, P < 0.0001 and β = −0.351, P = 0.039) and multivariable analysis (β = 0.911, P < 0.0001 and β = −0.416, P = 0.016). Conclusion: Compared to the fellow eyes, APAC eyes had different ocular biometric parameters. In addition to known biometric parameters associated with pupillary block (narrower anterior biometric parameters-ACA, ACD, and AOD), our study found multiple nonpupillary block factors such as higher lens vault and thinner and more anteriorly placed ciliary body to be associated with APAC.

Purpose: To compare the clinical and biometric characteristics of children presenting with nanophthalmos (NO group) with that of age-matched controls (CO group). Methods: Electronic medical records of 40 children (17 mm. Multivariable regression analysis revealed a significant correlation of SE and ACD with AxL. Conclusion: Nanophthalmos in children often present as amblyopia with visual impairment and strabismus. NO group with AxL

We aimed to study the histopathological and immunohistochemistry features in clinically diagnosed cases of nanophthalmos using light microscopy. This was an observational comparative study. We enrolled four eyes of four consecutive patients with nanophthalmos and visually significant cataract, who underwent cataract surgery with prophylactic posterior sclerostomy. Histological analysis of the excised scleral tissue was done and compared with age-matched cadaver controls between January 2021 and October 2021. Hematoxylin and Eosin (H&E) stains were used for histological analysis, and was further supplemented with immunohistochemistry (IHC) and immunofluorescence (IF) analyses using a simple light microscope. The immunostained sections were analyzed using confocal microscope for the fibronectin expression level. The main outcome measure was demonstration of histological changes of sclera in nanophthalmic eyes undergoing cataract surgery. Light microscopic features of nanophthalmos revealed thick fibers with fraying and lightly stained cores, irregular serrated edges, and randomly interspersed fibroblasts compared to regular arrangement of collagen fibers seen in cadaver controls. Immunohistochemistry analysis with anti-fibronectin antibody showed strong positivity in clustered fibers in nanophthalmos, and less intense diffuse staining in cadaver tissue. Histoclinical correlation was observed in one nanophthalmic scleral tissue with axial length less than 17 mm showing severe disorganization with diffuse collagenization, loss of fibrillary architecture compared to another specimen with axial length more than 17 mm. Simple, cost-effective light microscopy using basic stains was effective in identifying the characteristic histopathological features in nanophthalmic eyes, and this was further highlighted by immunohistochemistry and immunofluorescence analyses.

Microspherophakia is a rare congenital anomaly characterised by an increased anteroposterior thickness of the lens associated with a reduced equatorial diameter. The primary pathology lies in the development of zonules. Glaucoma is a serious complication associated with this disorder. We report a rare instance of bilateral crowning of the lens equator with secondary angle closure glaucoma in a middle-aged female with microspherophakia.

We report an unusual presentation of spontaneous hyphema in a young male with Axenfeld − Reiger syndrome (A-R syndrome) and developmental glaucoma. This rare presentation of A-R syndrome with spontaneous hyphema and dilated iris vasculature has been reported in mice eyes with COL4A1 mutation, but not in human eyes.

Purpose: COVID-19 pandemic has affected the healthcare system worldwide hindering the continuum of treatment of chronic disease patients. The objective of the study is to analyze the barriers encountered by the glaucoma patients for the follow-up visit and medication adherence during the pandemic. Methods: This cross-sectional study included glaucoma patients who did not attend the scheduled appointment from April 1, 2020 to July 31, 2020 in a tertiary eye care center (88.21%). Eligible patients of age >18 years and advised antiglaucoma medication in Madurai Zone were interviewed with validated questionnaire through telephonic call. Results: 363 patients answered the questionnaire through telephonic interview. 57.3% of the patients were found to be non-adherent to medication. The main barriers for glaucoma follow-up visit during the pandemic were lockdown restriction, transport problem, and financial difficulties. The top barriers for medication adherence were non availability of medication (54.81%), financial difficulties (30.29%), did not feel much improvement with eye drops (20.19%). On multiple regression analysis, longer distance to hospital, low socioeconomic status, more than one antiglaucoma medication use, lack of awareness of glaucoma, non-complaint before COVID-19 and stress due to the pandemic were found to be significant factors for medication non adherence. Conclusion: COVID-19 pandemic has emphasized the need for reformation in health care system for accessibility of medical care to patients in rural areas. Decentralization of health system to primary care level and utilization of teleophthalmology should be considered by health care planners in future.

A 42-year-old female patient has been referred for high intraocular pressure (IOP) in both eyes (BE). Examination revealed dilated, tortuous conjunctival, and episcleral vessels in BE with no apparent cause, also the patient had advanced glaucomatous damage in the left eye (LE). A diagnosis of bilateral idiopathic elevated episcleral venous pressure with secondary open-angle glaucoma (Radius Maumenee syndrome) was made. She was treated with aqueous suppressants in BE and underwent Partial diode cyclophotocoagulation in LE for control of high IOP. Nearly 50–55 cases have been reported till now. We publish here as this is a rare entity; also we discuss certain management controversies and provide literature review about this entity.

Purpose: To present a selected case series of advanced glaucoma-associated peripapillary and macular retinoschisis and response to various treatment strategies with a comprehensive literature review. Methods: Retrospective observational case series. Retrospective review of five selected cases of advanced glaucoma with peripapillary and macular retinoschisis. Results: All five patients had advanced glaucomatous damage with macular and peripapillary retinoschisis, three (patients 2, 3, and 5) had a neurosensory detachment of the macula. Increased intraocular pressure was managed with maximal antiglaucoma medications and G6 micropulse diode laser treatment in the first patient, transscleral diode laser in the second patient, mitomycin-C augmented trabeculectomy in the third patient, maximal antiglaucoma medications alone in the fourth patient, pars plana vitrectomy followed by trabeculectomy in the fifth patient. Conclusion: We speculate that peripapillary and macular retinoschisis may indicate a vision-threatening sequelae of advanced glaucoma. The probable inciting factor for this vision-threatening pathology being elevated intraocular pressure, fluctuations in intraocular pressure, and chronic glaucoma with advanced cupping. We emphasize that meticulous examination of the macula in patients with advanced glaucoma is mandatory. It is imperative to do OCT macula in patients with advanced glaucoma to diagnose this distinct entity at an earlier stage and preserve the existing visual potential.

Cyclodialysis clefts are rare. The most common reason for presentation is blunt ocular trauma followed by various iatrogenic interventions. Although gonioscopy is the gold standard technique, diagnosis is particularly challenging, and various noninvasive techniques such as ultrasound biomicroscopy and the newer anterior segment swept-source optical coherence tomography have been found effective. The management of cyclodialysis clefts should be conservative initially followed by a variety of nonsurgical and surgical modalities to achieve closure. In this article, we report the most recent developments in the diagnosis and surgical and nonsurgical treatment strategies of cyclodialysis cleft. An extensive literature search was done using PubMed and Google Scholar with the search terms such as cyclodialysis cleft, ocular hypotony, hypotony maculopathy, cyclopexy, and cyclotamponade.

Juvenile open-angle glaucoma (JOAG) is a subset of primary open-angle glaucoma, which affects individuals aged 5 to 35 years. Keratoconus is a bilateral progressive ectatic disorder of the cornea that results in a reduction of vision due to irregular astigmatism. The exact cause and the underlying pathological mechanism are unknown, but both environmental and genetic factors are thought to contribute to the development of the disorder. The association between keratoconus and normal-tension glaucoma has been widely published in literature, whereas the association between keratoconus and JOAG has been reported rarely. This is the third case report pointing toward the possible association of juvenile glaucoma with keratoconus, which emphasizes the importance of thorough glaucoma evaluation among keratoconus patients.

We report an interesting case report on idiosyncratic reaction of topiramate causing bilateral secondary acute angle-closure glaucoma with glaukomflecken, which mimicked acute primary angle closure (APAC) with nongranulomatous uveitis and choroidal effusions. After conservative management, signs and symptoms stabilized within 72 h, but the patient developed posterior synechiae with intermittent peripheral anterior synechiae (PAS) in BE, which was more prominent in LE. Here we report this case because presentation of topiramate-induced idiosyncratic reaction with glaukomflecken and subsequent resolution with posterior synechiae and PAS were rarely documented in literature. A detailed history taking and meticulous clinical evaluation helped us differentiate from APAC.
