Erythema nodosum leprosum (ENL) is an acute, exaggerated systemic immunological reaction that complicates the course of this chronic indolent disease. We present an ocular immunohistochemical study of severe form of ENL involving even the ciliary body and choroid resulting in the perforation of the globe on the initiation of anti leprosy therapy. We used CD-3, CD-68, S-100, and CD-20 for immunohistochemistry. It revealed plenty of CD-3-positive T-cells and CD-68-positive macrophages and a few S-100 and CD-20-positive cells. The inflammatory exudates stained positive for IgG and IgM. The diagnosis was ocular ENL. }, URL ={https://journals.lww.com/ijo/pages/default.aspx/article.asp?issn=0301-4738;year=2020;volume=68;issue=9;spage=2028;epage=2030;aulast=Rathinam;t=6}, eprint ={https://journals.lww.com/ijo/pages/default.aspx/article.asp?issn=0301-4738;year=2020;volume=68;issue=9;spage=2028;epage=2030;aulast=Rathinam;t=6} }
