Eales disease: A case report

Ronald Y Tiu, Milagros H Arroyo

The ocular manifestation of Eales Disease results from overlapping stages of vasculitis, occlusion, and neovascularization. This mimics several disease entities ranging from infectious to inflammatory causes. We report a case of a young healthy Filipino male with few months painless monocular sudden blurring of vision. On eye exam, there was vitreous hemorrhage with ultrasound evidence of retinal detachment on the bad eye. The good eye, on the other hand, has perivascular sheathing of peripheral vessels, which, on fluorescein angiography showed dye staining, extravasation, vessel obliteration, capillary dropouts, and collateral formation. Laboratory studies were normal except for positive PPD skin test. Infectious and inflammatory entities were considered less likely and Eales disease as a more probable diagnosis. The patient underwent pars plana vitrectomy on the bad eye where intraoperatively revealed fibrovascular fronds and an attached retina. Pan-retinal photocoagulation was also done on both eyes. Visual acuity after 3 months was 6/6 for both eyes. Management of Eales disease is similar to other vasoocclusive diseases where prevention of further ischemia and neovascularization is the main goal of treatment.
