Abstract

AIM- To quantify and compare the vessel density(VD) in the Superficial capillary plexus(SCP), Deep capillary plexus(DCP) and the size of the Foveal avascular zone(FAZ) before and after PRP. DESIGN- Prospective interventional case study. METHOD- 24 eyes of 14 patients with PDR and no CSME underwent measurement of best-corrected visual acuity(BCVA), fluorescein angiography, spectral-domain OCT and OCT angiography(OCTA) at baseline and 6th month. Patients received PRP within 7 days from baseline and underwent a mean of three lasers, using frequency-doubled Nd:YAG laser. RESULTS- The BCVA and central foveal thickness (p>0.05) remained unchanged. No statistically significant difference was noted in the VD and the FAZ for both SCP (p=0.58) and DCP (p=0.35) after PRP. CONCLUSION- OCT-A parameters were unchanged by PRP at 6 months suggesting that neither does PRP cause inflammation and occurrence of macular edema nor does it affect the vascular perfusion in any significant way.
