A 32-year-old male presented with a painful subconjunctival horseshoe shaped swelling around the limbus in the superior part of the bulbar conjunctiva with surrounding chemosis and congestion [Figure 1]. On examination, the lesion was found to be covering almost the whole of the upper part of the limbus as in Figure 1.
