Abstract

Objective. This case is an example of how newer advances in optical coherence tomography can aid in diagnosis of anterior segment disease. Background. Optical Coherence Tomography (OCT) uses emission and reflection of light to look at crosssections of ocular tissue. OCT in the past has only had the capability of imaging retinal layers. Newer programs have allowed OCT to image anterior segment structures such as the cornea, iridocorneal angle, and the iris. Methods. A second year optometry student was sitting as a patient for gonioscopy laboratory where an abnormal elevated ridge was noted within his iris structure of the right eye. Anterior segment OCT was used to take an image of the iris lesion. Results. The OCT revealed a hyporeflective cystic space within the iris that is consistent with an iris cyst. Conclusion. Anterior segment OCT is a newer technology that can aid in clinical diagnosis and follow progression of anterior segment disease.
