Abstract

Introduction: Retinopathy of prematurity (ROP) is one of the few causes of visual impairment in premature infants. Timely screening and initiation of treatment would prevent long term visual disability.

Setting: Neonatal Intensive Care Unit (NICU), Teaching Hospital, Peradeniya (THP)

Objectives: To determine the incidence of ROP in the NICU, THP and to use the results of the study to initiate a ROP screening programme for this unit.

Method: All consecutive babies admitted to the NICU over a 16 month period from 01-02-2003 were included in the study. Data for all patients admitted to the NICU were entered individually into a standard data sheet. Eligible patients were identified according to the International Screening Guidelines and comprised all preterm neonates with birth weight less than 1500g and/or gestational age less than 32 weeks and any other neonate outside the above inclusion criteria, who had an unstable clinical course. First screening examination was carried out at 32 weeks post conceptional age or 6 weeks postnatal time whichever came first. Follow up examinations were done until the resolution of ROP or up to retinal maturation.

Results: There were 130 admissions to the NICU during the study period. Of that106 were eligible for screening. Eighteen of the 106 neonates had varying degrees of retinopathy. Fifteen neonates were found to have significant ROP (i.e. stage 3 and beyond) resulting in an incidence of 11.5% among the high risk population of neonates at THP.

Recommendations: A larger study population would be needed to analyze the association of various risk factors such as steroids, gestational age, birth weight, oxygen administration, and duration of ventilation in the pathogenesis of ROP. It will be necessary to audit the screening programme in a few years time to assess its effectiveness.
