Bilateral maculopathy in a thalassemia patient on iron chelation therapy: a case report
ABSTRACT A 10-year-old Malay girl with underlying HbE/beta-thalassemia, on regular blood transfusion and deferoxamine iron chelation therapy, presented with two-month history of bilateral blurring of vision. On examination, her vision was 6/36 both eyes. Other optic nerve functions were normal. Anterior segment examination of both eyes was unremarkable. Fundus examination of both eyes revealed dull foveal reflex. Optical coherence tomography of both maculae showed increased central subfield thickness. Fundus fluorescence angiography showed patchy hypofluorescence over macular region for both eyes and late staining, indicating retinal pigment epithelium anomalies. A diagnosis of iron-chelation-therapy-related bilateral maculopathy was made. Patient was co-managed with pediatric hematology team to adjust the dose of deferoxamine, and was given three monthly appointments to monitor the progression of maculopathy at the ophthalmology clinic. However patient defaulted ophthalmology follow-up after the first visit.
