Prcis: We developed a deep learning-based classifier that can discriminate primary angle closure suspects (PACS), primary angle closure (PAC)/primary angle closure glaucoma (PACG), and also control eyes with open angle with acceptable accuracy.
Purpose: To develop a deep learning-based classifier for differentiating subtypes of primary angle closure disease, including PACS and PAC/PACG, and also normal control eyes.
Materials And Methods: Anterior segment optical coherence tomography images were used for analysis with 5 different networks including MnasNet, MobileNet, ResNet18, ResNet50, and EfficientNet.
Background: The utilization of corneal biomechanical features in evaluating glaucoma and its progression has received particular attention. The severity of corneal biomechanical changes can play an essential role in response to medical or surgical treatment. The present study evaluated the biomechanical features of the cornea in glaucoma patients in different subtypes and compared them with the normal condition.

There are different surgical options for handling visually significant cataract and mild-to-moderate open-angle glaucoma (OAG). We aimed to compare the one-year results of phacoemulsification alone versus phacoviscocanalostomy in these patients.

Methods: In this comparative interventional case series, 41 eyes of 40 patients having open-angle glaucoma (OAG) underwent sutureless scleral tunnel phacotrabeculectomy (Group A) and 28 eyes of 24 patients underwent the same procedure with placement of anterior capsule remnant in the tunnel (Group B). Baseline intraocular pressure (IOP) and IOP at 1 day, 1 month and 6 months after surgery were recorded.
Purpose: To evaluate the effect of postoperative latanoprost administration on central macular thickness (CMT) after uneventful cataract surgery in glaucoma patients.
