Unilateral Microphthalmia

Types of Unilateral Microphthalmia:

Unilateral microphthalmia can be categorized into two main types:

1. Simple Microphthalmia:
   • In simple microphthalmia, the affected eye is smaller but has a normal structure.
2. Complex Microphthalmia:
   • Complex microphthalmia involves not only a smaller eye but also abnormalities in the eye’s structure, such as missing or improperly formed parts.

Causes of Unilateral Microphthalmia
