Histopathological, immunohistochemical and molecular biologic study of an enucleated specimen of a case of Eales' disease.

Eales' disease is a retinal vasculitis characterized by retinal inflammation, ischemia, and neovascularization. Exact pathogenesis of this disease is yet to be found out. We present a 29-year-old male, diagnosed with Eales' disease in both eyes with persistent intraocular inflammation. Enucleation of the pthisical right eye was subjected for histopathological examination immunohistochemistry and molecular biologic study for mycobacterial tuberculosis DNA. Our study showed that Eales disease is probably a T cell mediated disease which is triggered by mycobacterial TB DNA. Further studies are needed to confirm our findings.
