Primary glaucoma associated with iridotrabecular dysgenesis and ectropion uveae

Area of Science:

• Ophthalmology
• Genetics
• Pathology

Background:

• Congenital ectropion uveae is a rare condition characterized by hyperplasia of the iris pigment border.
• It is often associated with iris hypoplasia and specific gonioscopic findings.

Observation:

• Nine patients with unilateral congenital ectropion uveae were studied.
• A majority also presented with mild ptosis, but no systemic abnormalities were noted.
• The condition involves the spread of iris pigment epithelium onto the anterior iris surface.

Findings:

• Histopathologic and electron microscopic analyses were performed on two patients.
• The apparent ectropion uveae is due to iris pigment epithelium extending beyond the iris ruff.
• Glaucoma was a significant comorbidity in all studied patients.

Implications:

• Congenital ectropion uveae necessitates careful, periodic ophthalmic examinations.
• Early detection of glaucoma is critical for managing this condition.
• Understanding the histopathology aids in diagnosing and monitoring patients.
