Optical Coherence Tomography to Evaluate Dengue

Dear Editor, The recent report you published on the use of optical coherence tomography (OCT) to evaluate dengue was very interesting [1]. Rhee and Han [1] concluded that "Follow-up examination of individuals with dengue fever and associated visual impairment should involve the use of OCT to evaluate visual acuity and visual field change." In fact, the ocular complications of dengue are typically overlooked, as a proper examination is rarely performed. As Mendes et al. [2] noted, "Dengue fever can lead to visual impairment detectable by ophthalmological exams such as angiography, retinography, and OCT imaging, as well as retinal and cortical electrophysiology." Severe dengue, dengue shock, also tends to cause complications [3]. Close follow-up of these patients is required and ocular examination should be included in the clinical practice guidelines.
