A study of anterior chamber angle biometric measurements in closed angle glaucomas and healthy subjects using imaging tool

This observational study aims to examine the ability of an imaging tool in differentiating between anterior chamber angle biometric measurements of closed angle glaucomas and healthy subjects.:This was a hospital based cross-sectional observational study. Seventy five subjects were grouped into three groups of 25 subjects each based on appropriate inclusion and exclusion criteria. Using AS-OCT, major outcome variables measured wereanterior chamber depth, lens thickness, lens vault and anterior opening distance 750 (AOD 750). Intraocular pressure and axial length were also noted.Statistical analysis showed that there was significant difference in IOP(p=0.02), axial length (p=0.0001), lens thickness (p=0.0001) and lens vault among the studied groups.The study results show that in phacomorphicglaucoma, anterior chamber depth was less and lens vault, axial length & angle opening distance 750 were more as compared to acute primary angle closure glaucoma.
