Retinopathy of prematurity: a study.

A total of 50 infants of less than 2000 gm birth weight were screened for retinopathy of prematurity (ROP) by binocular indirect ophthalmoscopy. The incidence of ROP was found in 19 patients (38%). Of these, 8 patients (16 eyes) had threshold disease. Significantly, occurrence of threshold ROP was seen in both 1600 gm birth weight in one infant and in the absence of oxygen administration in 2 infants. Ten of the 16 eyes underwent therapeutic intervention while 6 eyes did not receive treatment for lack of consent from the parents. The treatment consisted of indirect laser photocoagulation (8 eyes) and transconjunctival cryopexy (2 eyes). Good regression of the disease (favourable outcome) was noted in all the treated eyes.
