Entropion is in common language inward turning of the eyelid margin. This causes trichiasis (lash-cornea touch), where the eyelashes are directed inwards toward the globe. This malposition can cause corneal irritation due to constant touch by the lashes.
The MRI scan showed a large intraconal well defined mass sitting right next to the optic nerve causing mass effect which in turn was causing diminution of vision. My working differentials going into surgery- based on location and imaging was Cavernous Hemangioma, Fibrous Histiocytoma, Dermoid cyst, Schwannoma among others.
