Utility of pattern recognition and multimodal imaging in the diagnosis and management of doyne honeycomb retinal dystrophy complicated with type one choroidal neovascular membrane.

A 44-year-old woman presented with decreased vision in both eyes. The retina in both eyes had drusen distributed along vascular arcades, central macula and in peripapillary region. Macula had pigmented scarring and exudation. Fundus autofluorescence showed drusen. Optical coherence tomography showed drusen, subretinal and intraretinal fluid. Fundus fluorescein and indocyanine green angiography showed drusen, retinal pigment epithelial atrophy and vascular network. Younger age at presentation, bilateral symmetry, typical distribution of drusen along the arcades in a radiating pattern, peripapillary involvement, scarring and atrophy at macula were suggestive of doyne honeycomb retinal dystrophy. The reduced vision was due to macular atrophy and an active choroidal neovascular membrane. The patient was treated with antivascular endothelial growth factor injections for choroidal neovascular membrane. Our case highlights the importance of pattern recognition and multimodal imaging for diagnosing the type of macular dystrophy as doyne honeycomb retinal dystrophy, while simultaneously managing choroidal neovascular membrane.
