Abstract

STUDY DESIGN: Hospital Based Cross Sectional Study
PURPOSE: To compare Axial Length in various subtypes of Primary Angle Closure Disease using Laser Interferometry
METHODS: 40 Primary Angle Closure Disease (PACD) cases were enrolled; 16 Primary Angle Closure Suspects (PACS), 15 Primary Angle Closure (PAC) and 9 Primary Angle Closure Glaucoma (PACG). Axial Length (AL) measured using Laser Interferometry.
RESULTS: Axial Length (AL) found to be shallower in PACD than normal population. The AL in PACS, PAC, PACG were 2.17 ± 0.09mm, 2.06 ± 0.11 mm and 2.30 ± 0.20 respectively, suggesting predictability of AL in subtypes as suggested by significant p-value using one-way ANOVA test keeping 5% level of significance.
CONCLUSION: Thus, AL values can aid in identifying at-risk groups of PACD and also significant association in AL values exist between PAC vs PACG.
