Objective: The objective of the study was to compare the posture-induced intraocular pressure (IOP) changes in primary angle-closure glaucoma (PACG) with or without glaucoma medications, and healthy control eyes with normal IOPs in Indian subjects. Materials and Methods: The IOP was measured in the sitting position and the supine position after 10, 20, and 30 min with a rebound tonometer. Results: Twenty-five patients with PACG and 30 controls with normal IOPs were studied. The IOP in the sitting position measured with the rebound tonometer was 13.8 + 3.2 mm Hg in eyes with PAC, and 12.9 + 2.9 mm Hg in eyes with normal IOPs. The IOP increased to 14.4 mm Hg, 16.8 mm Hg, and 18.9 mm Hg at 10 min, 20 min, and 30 min in PACG subjects. In normal age-matched controls, the IOP increased to 13.4 mm Hg, 14.9 mm Hg, and 17.8 mm Hg at 10 min, 20 min, and 30 min, respectively, but none of these differences were significant (P = 0.09; P = 0.08, P = 0.08). The mean postural IOP change from baseline was also not significant between the two groups. Only three patients were on single antiglaucoma medication with well-controlled IOP in the PACG group. Conclusions: Postural IOP changes are comparable among eyes with PACG with and without glaucoma medications, and control eyes.

The introduction of anterior-segment optical-coherence tomography (AS-OCT) has led to improved assessments of the anatomy of the iridocorneal-angle and diagnoses of several mechanisms of angle closure which often result in raised intraocular pressure (IOP). Continuous advancements in AS-OCT technology and software, along with an extensive research in the field, have resulted in a wide range of possible parameters that may be used to diagnose and follow up on patients with this spectrum of diseases. However, the clinical relevance of such variables needs to be explored thoroughly. The aim of the present review is to summarize the current evidence supporting the use of AS-OCT for the diagnosis and follow-up of several iridocorneal-angle and anterior-chamber alterations, focusing on the advantages and downsides of this technology.

Iridocorneal Angle

Plateau iris syndrome (PIS) is a frequent cause of angle closure. Argon laser peripheral iridoplasty (ALPI) has been proposed in PIS to widen the iridocorneal angle. The objective of the present study was to perform a systematic review of the available studies evaluating the efficacy of ALPI on intraocular pressure (IOP), iridocorneal angle opening and the number of medications in patients with chronic angle-closure associated with PIS. One prospective and seven retrospective studies with a minimum 1 month of follow-up were included. Although ALPI seemed to lower IOP, to decrease the number of topical antiglaucoma medications and widen the iridocorneal angle shortly after the procedure, there is no current evidence of long-term efficacy. To date, there is no robust scientific evidence to advocate ALPI as a treatment for chronic angle-closure caused by PIS.

Purpose:  To determine the change in intraocular pressure after cataract surgery in patients diagnosed with glaucoma. Study Design:  Interventional case series. Place and Duration of Study:  Glaucoma Clinic. Al-Ibrahim Eye Hospital (AIEH) Karachi, Pakistan from May to October, 2019. Methods:  Thirty-eight patients diagnosed with glaucoma and cataract and registered in glaucoma clinic were recruited for this study. Inclusion Criteria was age > 41 years and patients diagnosed with primary open/closed angle glaucoma and cataract. Patients with secondary glaucoma, history of trabeculectomy and any other ocular diseases were excluded from the study. Pre-operative assessment was done for phacoemulsification. In post-operative examination, first and second follow-up IOP was measured. Data analysis was done on statistical package for social science (SPSS) version 20.0. Statistical changes were present in the form of bar chart, frequency and graphs. The mean standard deviation for pre-operative, post-operative 1st and 2nd follow-up IOP was calculated. Results:  A total of 38 participants and 48 eyes satisfied the inclusion criteria. Out of 48 eyes, 39 (81.3%) eyes were diagnosed with Primary open angle glaucoma and 9 (18.8%) eyes with Primary Angle Closure Glaucoma. The pre-operative mean IOP was 16.56 ± 6.67 mm Hg and post-operative mean IOP at first follow-up was 13.39 ± 4.04 mm Hg. At second follow-up at one-month mean IOP was 12.14 ± 2.28 mm Hg. Conclusion:  Phacoemulsification produces a useful decrease in IOP in glaucoma patients. Key Word:  Glaucoma, Cataract, Phacoemulsification, Intraocular Pressure.
