Anterior segment optical coherence tomography parameters in subtypes of primary angle closure glaucoma

Abstract

Background: Anterior segment optical coherence tomography (AS-OCT) offers a non-contact method for high resolution cross-sectional imaging of the anterior segment and its structures by measuring their optical reflections. This project's objective was to research the significant value of ASـOCT parameters in subtypes of primary angle closure glaucoma (PACG). Methods: This is an observational, prospective cross-sectional research on 60 eyes of patients with PACG. There were three distinct groups of patients: Group (PACS) (n=18): primary angle closure suspect. Group (PAC) (n=18): primary angle closure. Group (PACG) (n=24): PACGResults: Angle Opening Distance (AOD) 500 NAS and Trabecular-Iris Contact Length (TICL) NAS discrepancies across the groups (p1, p2 and p3) were statistically different. In the group P1, there were substantial variations in iris thickness measured by the 750 Trabecular Meshwork (TEM). In the PACG and PAC groups, respectively, there was a highly significant negative connection between the lens vault and the AC depth and width. The lens vault and TICL at the temporal angle had a substantial negative association in the PAC group and an elevated correlation in the PACG group. Cup-to-disc (C/D) ratio, lens vault, AOD500 at nasal angle, Iris curve at nasal and temporal angle, Iris thickness at temporal angle, TICL at both temporal and nasal angle are predictor parameters in subtypes of primary angle closure.Conclusions: ASOCT can be used to assess anterior chamber angle. AS-OCT has a role to determine which parameters are the strongest predictive factors of subtypes of PAC. AS-OCT will be employed as a diagnostic tool for glaucoma patients' diagnosis and maybe their therapy.
