Abstract

Aim: To assess changes in retinal microvasculature pre and post YAG capsulotomy
Methods: This is a prospective study where patients presenting with posterior capsular opacification were included. Patients with existing retinal pathology, glaucoma were excluded. All patients underwent OCT angiography pre and post YAG capsulotomy at 1 week and 1 month. Macular thickness, foveal avascular zone (FAZ) area, blood vessels density (BVD) at deep and superficial plexus was compared.
Results: Twenty nine patients with mean±SD age of 56.23±4.7 years were included. FAZ area, FAZ perimeter perimeter was found to be similar (P>0.05). Superficial BVD was found to be similar at all eccentricities (P>0.05) however deep BVD were significantly different in temporal, inferior and superior quadrant at peripheral eccentricities (P<0.05).
Conclusion: Yag capsultomy results in retinal vascular changes at deep plexus and in peripheral eccentricities however longer follow up could provide more insights.
