Paediatric Ophthalmology

Visual screening of the newborn allows early detection of potentially blinding conditions. One of the test
is to look for the presence of red reflex. Its absence may indicate cataract or more seriously retinoblastoma.
Retinopathy of prematurity results from attempted vascularization of the peripheral retina. Although many 
factors have been implicated, the most consistent risk factors for ROP are low birth weight and degree of
prematurity. Lengths of time in oxygen and with mechanical ventilation have also been correlated with the 
development of ROP, but no correlation could be established with levels of oxygen saturation, as measured 
directly or transcutaneously.
