Abstract :
Purpose: 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.
Materials and Methods: 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.
Results: 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.
Conclusion: 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.
