OBJECTIVE: To describe the clinical spectrum of fundus manifestations and angiographic and optical coherence tomographic features of dengue-associated maculopathy in a large series.
METHODS: We reviewed clinical records of patients diagnosed as having dengue maculopathy at the Singapore National Eye Centre between January 1, 2002, and December 31, 2005.
RESULTS: We identified 41 patients with serological evidence of dengue fever who had ocular signs and symptoms not attributable to other diseases within 1 month after onset of symptoms of dengue. Seventy-one eyes had maculopathy. Mean best-corrected visual acuity in the affected eye was 20/40 (range, hand motions to 20/20). Intraretinal hemorrhages were seen in 45% of eyes, usually in association with venous sheathing. Fundus fluorescein angiography demonstrated venular occlusion in 25% or arteriolar and/or venular leakage in 3% and 13%, respectively. Yellow subretinal dots were an unusual finding in 28%. Of these, 50% showed corresponding hypofluorescent spots on indocyanine green angiography. Central or paracentral scotomas were observed in 63%. Twenty-eight patients received steroid treatment. Mean visual acuity showed significant improvement between weeks 2 and 4, with an increasing proportion of eyes achieving a best-corrected visual acuity of 20/40 or better across time.
CONCLUSION: Fundus fluorescein and indocyanine green angiography, optical coherence tomography, and visual field testing are useful tools in the diagnosis of dengue maculopathy.
