Acute Macular Neuroretinopathy in a 15-Year-Old Boy: Optical Coherence Tomography and Visual Acuity Findings
A 15-year-old Japanese boy presented with a 6-day history of acute painless blurred vision and a small central scotoma in the left eye. Best corrected visual acuity (BCVA) was 0.8 and 0.3 in the right and left eyes, respectively. Intraocular pressure was 16 mm Hg in both eyes. The patient had no specific past medical history. No inflammatory cells were observed in the anterior segment or vitreous of either eye. Fundus examination revealed no specific abnormalities in the right eye (fig. ). In the left eye, there was a small dark area in the fovea (fig. , fig. ). OCT (RS-3000; Nidek, Japan) revealed no specific abnormalities in the right eye; however, in the left eye, disruption of the photoreceptor inner segment (IS)/outer segment (OS) junction line and the OS/retinal pigment epithelium (RPE) line in the foveal area (fig. ) was found. The patient was monitored without treatment. After 1 week, BCVA had improved to 0.6 in the left eye and OCT revealed partial restoration of the IS/OS line with focal thinning of the OS/RPE line in the foveal area (fig. ). After 1 month, the patient's complaints had resolved and BCVA had improved to 0.8 in the left eye. OCT showed complete restoration of the IS/OS line and the OS/RPE line (fig. ). Fluorescein angiography, indocyanine green angiography, and multifocal electroretinogram were not available in this case.
