Sensory - Vision Abnormalities

Introduction

These notes introduce the abnormal development of the eye and vision associated structures.

Anophthalmia (absence of an eye) and microphthalmia (small eye within the orbit) have a combined birth prevalence of approximately 30 per 100,000 population. (More? Verma AS, Fitzpatrick DR., 2007)

Genetic factors include developmental transcription factors required for inductive/developmental events in the structure of the eye and retina development.

Environmental factors include gestational-acquired infections, maternal vitamin A deficiency, smoking, X-ray exposure, solvent misuse and thalidomide exposure.
