Colobomatous Optic Neuropathy
- Congenital cleft in optic disc tissue from faulty embryogenesis
- Often misdiagnosed as glaucoma
- Other congenital forebrain and non-brain anomalies are often present
- Suspect optic disc coloboma if there are clefts in the eyelid or iris
- Distinguish from high myopia, glaucoma
- Order brain imaging to detect other forebrain anomalies
- Be aware of the association with papillorenal syndrome
- Optic disc and visual field defects will be lifelong and stable
- Clinical outcome depends on other anomalies

Trap: optic disc coloboma is often misdiagnosed as glaucoma, initiating unnecessary treatment
