“…Several immune-mediated diseases including Behcet's disease, sarcoidosis, rhematoid arthritis, Vogt-Koyanagi-Harada, Wegener's granulomatosis, and Crohn's disease causing retinal vasculitis are known to be associated with lymphocytic infiltration of the affected tissues. [32][33][34][35][36][37][38][39][40][41][42][43][44][45] Since we had excluded all the aforementioned conditions, lymphocytic infiltration in the ERMs was least expected. Our observation supports the hypothesis of triggering of immune mechanism by an unknown antigen in patients of Eales' disease resulting in active perivasculitis and resultant cascade of events observed at different stages of the disease process.…”
