Abstract:
We screened 50 neonates fulfilling the inclusion criteria admitted during the study period in a teaching hospital in a north-eastern state of India. Out of 50 neonates screened, 22 (44%) developed retinopathy of prematurity. There was significant association between the birth weight and gestational age of the baby at the time of the delivery with the development of ROP. Multivariate analysis of risk factors for development of ROP using a stepwise method, after controlling for various potential confounders, showed that apnea was a significant risk factor for the development of retinopathy of prematurity.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
