Orbital cyst and optic disc pits are both congenital embryological anomalies. Orbital cysts occurring in association with optic disc colobomata and microphthalmic eyes have been widely reported in literature. The authors describe the case of a 69-year-old man with an asymptomatic orbital mass, who was investigated and found to have a coexistent optic disc pit and orbital cyst. The axial length was normal. Visual acuity was reduced due to epiretinal membrane at the macula as a consequence of serous maculopathy secondary to the optic disc pit. No active intervention was offered due to poor visual potential, and no changes in the cyst occurred over time. This is an unusual case of coexistent orbital cyst and optic disc pit in an eye with normal axial length, although the dual pathology has previously been described in a microphthalmic eye.
