Abstract

Purpose:

To report an orbital cyst underlying a chorioretinal coloboma in an otherwise normal eye, detected by spectral domain optical coherence tomography imaging. To the authors’ knowledge, this is the first case of a chorioretinal colobomatous cyst in the normal eye to be reported.

Methods:

A descriptive case report of a patient with a chorioretinal coloboma with an underlying orbital cyst.

Results:

A 59-year-old woman presented with a floater affecting her left visual field. Fundoscopy revealed a pale lesion inferotemporal to fixation at the left macula. Spectral domain optical coherence tomography revealed a retinochoroidal coloboma with an associated scleral hole. Enhanced depth imaging spectral domain optical coherence tomography revealed an underlying orbital colobomatous cyst.

Conclusion:

To the authors’ knowledge, this is the first case of a healthy adult with a retinochoroidal colobomatous cyst without microphthalmos. The authors encourage optical coherence tomography of any suspected colobomas to exclude similar pathology.
