A peripapillary colobomatous pseudo-duplication of the optic disc as seen in an asymptomatic 23 year old female with myopia referred for routine retinal periphery screening. Rest retinal exam was normal. Duplication of the optic disc can be classified as either true duplication or pseudoduplication, both of which are rare clinical conditions. Pseudodoubling of the optic disc is commonly caused by optic disc or peripapillary colobomas, characterized by a circumscribed, disc-like lesion with radiating vessels but only one normal optic nerve. A few cases have involved pathological myopia, moderate myopia, proliferative diabetic retinopathy and CHARGE syndrome. The lesion is often found inferior to the normal optic disc. The patient was advised regular follow ups.
