Use of Optical Coherence Tomography to Evaluate Visual Acuity and Visual Field Changes in Dengue Fever
A 40-year-old woman presented with an upper visual field defect in the left eye after contracting dengue fever 1 month prior. The right eye was normal. BCVA was 20 / 30 in the left eye, and no other abnormal findings were found in the anterior segment. Retina examination revealed RPE atrophy in the left eye. Fluorescein angiography (FA) of the left eye showed a patch choroidal perfusion delay and a window defect due to RPE atrophy. IR imagery demonstrated hypofluorescence in the superior nasal area including the fovea. OCT imagery revealed disruption of the IS/OS junction and outer retina thinning at the hypofluorescence site of the IR imagery.
