Optic neuropathy associated with dengue fever

Abstract

Purpose: To report a case series of three patients of optic neuropathy associated with dengue fever. Methods: Observational case series. Results: Three patients aged of 19,31, and 40 years (cases 1, 2, and 3) complained of unilateral blurring of vision within a week of being diagnosed with dengue fever. Their presenting visual acuities were counting fingers in cases 1 and 2, and 6/6 in case 3, with features suggestive of optic neuropathy. Two of the three patients (cases 2 and 3) had bilateral ocular signs. The visual acuity recovered to 6/9 in case 1, worsened to no light perception in case 2, and remained unchanged in case 3. Conclusions: Although spontaneous visual recovery is possible, optic neuropathy associated with dengue fever may result in severe and permanent visual loss.
