Retinopathy of prematurity: frequency measures in two tertiary care hospitals.
J Med Sci Jan ;19(3):148-51.

Objective: The study was conducted to measure the frequency of Retinopathy of Prematurity among the premature babies. Material and Methods: This study was conducted in two tertiary care hospitals of Peshawar, from January 2010 to April 2010. One hundred babies were registered and examined during the period. All these babies were premature weighing less than 1750gm and born before 35 weeks of gestation. All these babies were examined by a trained ophthalmologist. Indirect ophthalmoscopy was done after cycloplegic dilation at regular intervals as 1st follow up examination at 4 weeks of age, 2nd follow up at 6 weeks and 3rd follow up at 8 weeks on each baby. Results: 100 cases registered, frequency of Retinopathy of Prematurity found 0% among them. Out of these infants 68% were male while 32% were female, 79% infants examined from KTH and 21% from HMC. 66% infants belong to category I Low Birth Weight (LBW) while 34% belong to category II very low Birth Weight (VLBW) as for as gestational age concerned the highest percentage of the babies came from gestational age group 32weeks+6days. Conclusion: No case of Retinopathy of Prematurity was detected. This may be of so many causes, as the survival rate of premature births is very less as compared to the developed countries. Secondly the oxygen concentration provided to babies in neonatal units is very less, 50%-70% instead to 100% as given in developed countries.
