Abstract

Purpose-To compare the efficacy of Diode(810 nm red) vs Nd-Yag laser(532nm green) in ROP treatment.

Method-Prospective study conducted from Nov 2019-May 2021, 60 eyes of 30 babies with ROP where RE was treated by diode & LE of same baby by Nd-Yag laser with same risk factors. Laser performed within 48 hrs of diagnosis in classic ROP/immediately in Aggressive posterior ROP(APROP). On follow up we looked for signs of regression & complication.

Result-76.7% of eyes was either zone 1/2 stage 2/3 ROP, 66.7% was type 1 pre threshold and 10% was APROP. Mean GA of 28.6 weeks, BW of 1.37 kgs, laser spots of 3789 in RE & 3621 in LE. 50.5% of RE & 50.7% of LE regressed at 1st sitting. 56.6% required 2nd add on laser, 20% 3rd add on, 6.6% 4th add on. Stage 2/3 required 2-3 times laser therapy, 66.6% of APROP required 4 times.

Conclusion-APROP babies required laser multiple times than stage 2/3, with same rate of regression in BE. Diode & Nd-Yag laser are equally effective in ROP treatment.
