The Severity of Retinopathy in the Extremely Premature Infants.

Abstract

Objective: We aimed to investigate the incidence and the severity of retinopathy of extremely premature infants and to evaluate the risk factors and outcome of the cases.

Materials and methods: Out of 200 premature births, we retrospectively reviewed 9 cases that developed ROP. We excluded cases where ROP developed in newborns > 30 weeks of gestational age and cases where medical notes were unavailable or incomplete. Topical drops of cyclopentolate 1% and phenylephrine 5% were instilled and fundoscopy was performed using a direct ophthalmoscope.

Results: The incidence of ROP was 4.5% in the 9-year period. The infants were divided into two groups. Group 1 included premature infants ≤27 weeks of age and Group 2 included those >27 weeks but ≤ 30 weeks of age. We found that the infants of Group 1 showed advanced stages of ROP in comparison to Group 2. Out of 18 eyes, 11 eyes had stage 3 ROP and they were all found in Group 1 (100% of cases).

Conclusion: The severity of ROP was associated with earlier gestational age, lower birth weight, and oxygen supplementation. Constant cooperation between physicians and nursing staff is necessary to avoid undetected cases and further prevent ROP related blindness.
