Developmental Anomalies

They are Albinism and Cataract

Albinism: is a hereditary congenital condition characterized by relative absence of pigment from the skin, hair, choroid coat and iris.

It is often accompanied by

  • Refractive error
  • Lowered vision acuity
  • Nystagmus (quick jerky movement of the eyes usually lateral but occasionally in a rotator or vertical direction.)
  • Photo phobia (extreme sensitivity to light)

Cataract: Is the condition of the eye in which the crystalline lens or its capsule becomes opaque, with resultant loss of visual acuity.
