Abstract

Diode laser photocoagulation with laser ophthalmoscope has been shown to be effective and safe for treatment of threshold ROP. The purpose of this study are to deternine whether diode laser photocoagulation is really effective in reducing the likelihood of unfavorable regults in threshold stage. The eyes of neonates with birthweight of 2,500g or less, gestational age of 37 weeks or less, or exposure to increased ambient oxygen between May 1994 and October 1995 were examined, 21 eyes of threshold level of ROP and 2 eyes of prethreshold stage received diode laser photocoagulation. Nineteen(83%) of the 23 eyes that underwent laser photocoagulation had a favorable respons. Retinopathy of prematurity, however progressed to stage 4 in 2 eyes and stage 5 in 2 eyes. Two eyes in stage 4 achieved retinal reattachment after retinal buckling operation, but two eyes in stage 5 did not achieved retina1 reattachment. Regarding complications, one eye had retinal hemorihagic spot and one had presumed Bruch's membrane rupture. All infants had been followed up for minimum of 6 months. The results suggest that diode laser photocoagulation is an effective method in treatment of ROP, technically easier to administer without significant complication.
