Optical coherence tomography in the diagnosis of subclinical serous detachment of the macula secondary to a choroidal nevus

We present a case in which optical coherence tomography (OCT) aided in the diagnosis of subretinal fluid (SRF) secondary to a choroidal nevus. A patie nt with a raised lesion above the left optic disc and distorted central vis ion was referred to our unit because of suspected choroid-al melanoma. Fund us fluorescein angiography and slit-lamp investigation did not indicate any areas of SRF; however, OCT showed serous detachment in the macular area. T he lesion was treated with laser photo coagulation and, when reviewed at fo ur weeks post-treatment, repeat OCT scans showed that the area of SRF had c leared. In this case OCT was able to detect a subclinical serous detachment in the macula. This may have important implications in the monitoring of p atients with small suspicious lesions.
