Abstract
Albinism represents a group of inherited melanin disorders,
presenting with nystagmus, iris transillumination, and reduced visual
acuity. Foveal and optic nerve hypoplasia together with optic track
misrouting are the most constant features. Perhaps there is a wide
transitional zone from normal to albinotic, rendering the diagnosis of
albinism is no longer just clinical. Although it can be broadly divided into
oculocutaneous and ocular albinism, advancements in molecular genetics
that have led to a reclassification of albinism into various subcategories.
VEP is diagnostic in questionable cases showing the classical atypical
chiasmal crossing. Management is directed to correct error of refraction,
and glare, low vision aids to assist visual impairment in albinism. Instruct
the child to use full sleeves and full pants, use broad brimmed hat to
protect the skin from sunrays. Rehabilitation is a crucial part, thus a team
work should include in addition to the ophthalmologist; a dermatologist, a
pediatrician, a rehabilitator and a genetic counselor. Potential molecular
based treatments are still area under research.
