Use of Optical Coherence Tomography to Evaluate Visual Acuity and Visual Field Changes in Dengue Fever
A 40-year-old woman presented with a 1-year history of afterimages in both eyes after having Dengue fever. Her best-corrected visual acuity (BCVA) was 20 / 20 in both eyes, and her intraocular pressure was normal. Slit examination revealed no abnormal findings. Retina examination revealed hemorrhaging in the retina inner layer and RPE atrophy in both eyes. Fluorescein angiography demonstrated fluorescence blockage by retinal hemorrhage. ICG showed late hypofluorescence due to choroidal filling disorder, and infrared (IR) imagery showed hypofluorescence that included both foveae. OCT imagery revealed disruption of the inner segment/outer segment junction (IS/OS) junction and outer retina thinning at the hypofluorescence site of the IR imagery ( and ).
