4 Ophthalmic Pathology and Intraocular Tumors
Part I: Ophthalmic Pathology
Chapter 8: Sclerax
Microphthalmia refers to a smaller than average eye with associated developmental defects (eg, persistent fetal vasculature). Colobomas and scleral defects with cystic outpouchings of intraocular contents (microphthalmia with cyst) are also common, because of failure of the fetal fissure to close completely.
See BCSC Section 6, Pediatric Ophthalmology and Strabismus, and Section 7, Oculofacial Plastic and Orbital Surgery, for additional discussion of microphthalmia.
