A 30-year-old male of Middle Eastern origin attended the practice for the first time. His sight had been tested previously elsewhere some three years before and he had been prescribed a myopic correction. The patient had never had any specific ocular or general health problems and this latest visit was routine. There were no visual complaints, no medical issues, no medication being taken and no family history of ocular issues. Refraction was RE −3.50/-1.75x172.5, LE −3.50/1.50x10 and corrected visual acuity was 6/5 at distance in each eye and N5 at near in each eye. Muscle balance was orthophoric at both distance and near. Both eyes appeared clear on external slit lamp examination but there was a suggestion of possible hypo pigmentary change at both right and left maculas using binocular indirect ophthalmoscopy, but without dilation. OCT was carried out undilated as part of routine assessment of the patient. Examination of the images showed a normal image for the right eye (Figure 1), but an anomaly on the image of the left eye where a significant indentation in the choroid nasal to the macula is visible (Figure 2). Further examination using an Amsler chart identified no distortion or breaks in the lines presented. The anomaly has been identified as focal choroidal excavation.
