Severe preterm delivery is defined as babies born at 32 weeks or less of gestation. The earlier the baby is born, the less likely he or she is to survive. Those who do survive are at a higher risk of lifelong health problems, of which the ophthalmic complications include retinopathy of prematurity, myopia, amblyobia, strabismus and optic nerve abnormalities. This study is to compare the ocular biometric parameters, optic nerve head parameters, and retinal nerve fiber layer thickness parameters between severe preterm and term Malay children aged 8-16 years old.

Intermittent exotropia is a condition in which the visual axes on the right and left eyes are straight but occasionally either eye deviates outward. Intermittent exotropia is the most common type of exodeviation and is usually first observed by the parents in early childhood. In some cases, an exophoria progresses to an intermittent exotropia that eventually becomes constant. Such deviation usually occurs first at distance and later at near fixation. They may be influenced by decreased tonic convergence with increasing age, the development of suppression, loss of accommodative power and...
