Abstract
Primary angle closure glaucoma may be preventable in the early stages if we can identify which kind of angles and/or persons are more likely to benefit from prophylactic treatment.
The current trend of diagnosis and management of PACG includes the characteristic optic disc changes and the characteristic gonioscopy findings.
The disadvantages of gonioscopy examination include being subjective, time consuming and non-user-friendly. Anterior chamber angle assessment using ultrasound biomicroscopy, an objective method, gives quantitative measurements and can illustrate the mechanism of angle closure but not without disadvantages and limitations. In order to overcome these problems either scheimuflug camera or anterior segment optical coherence tomography can be used being non -contact, objective, rapid image acquisition time and user friendly.
Our study is a cross-sectional study aiming to study the agreement between gonioscopic findings as the standard technique and AS-OCT findings as an objective method for anterior chamber angle estimation in eyes of glaucoma patients.
The study involved 80 eyes (20 eyes of primary open angle glaucoma patients at with 20 eyes of normal age-matched control and 40 eyes of PACG patient). The PACG eyes were subdivided, using dynamic gonioscopy into two subgroups PAC+ve (20 eyes with peripheral anterior synechiae and PAC-ve (20 eyes without synechiae). All the study participants underwent full ophthalmological assessment with gonioscopy using the Goldmann 3 mirror goniolens.
