case_images: a Clinical examination of the right eye revealed a purple lobulated subconjunctival mass located temporally. b AS-OCT over the lesion demonstrated hypo-reflective intralesional spaces within the mass. c These spaces were filled with hyper-reflective material causing back-shadowing.

case_images: Slit lamp examination revealed a dark red lobulated epibulbar lesion, on the temporal side of the right eye, measuring 7 mm x 5 mm (Fig. 1a). Anterior segment OCT (AS-OCT) over the lesion revealed multiple intralesional hypo-reflective spaces filled with moderate to high reflective material, causing back-shadowing, corresponding to blood-filled vascular lumens (Fig. 1b, c).
case_images: a Surgical resection of the lesion was done by passing a bridle suture underneath the LR muscle to stretch it, (b) followed by careful dissection of the mass from the muscle fibers. c A complete muscle-sparing tumor excision was achieved.

case_images: Bridle suture was passed under the muscle to stretch it, and complete excision of the tumor was done after careful dissection from the muscle fibers (Fig. 2).
case_images: a Histopathological examination of the specimen revealed a well-circumscribed proliferation of dilated, blood vessels (H&E stain, magnification x10). b The blood-filled venous spaces were lined by flat endothelial cells and separated by fibroconnective tissue (H&E stain, magnification x40).

case_images: Histopathology revealed a well-circumscribed proliferation of dilated, blood-filled venous spaces lined by flattened endothelial cells and separated by fibroconnective tissue of varying thickness, confirming the diagnosis of a cavernous IMH of an EOM (Fig. 3).
