Combined occlusion of branch retinal artery and vein secondary to prepapillary arterial loops.

A middle‑aged diabetic and hypertensive man presented with diminished vision in the left eye. Fundus examination revealed prepapillary arterial loops, but with features of venous rather than arterial occlusion. Fluorescein angiography and optical coherence tomography confirmed the presence of a branch retinal vein occlusion along with two branch retinal artery occlusions. The resultant macular edema responded well to intravitreal triamcinolone and laser photocoagulation though the visual improvement was moderate.

A rare case of benign isolated schwannoma in the inferior orbit.

A rare case of unilateral orbital schwannoma arising from the infraorbital nerve is presented. An excision biopsy with complete removal of the mass in the inferior orbit was performed. A definitive diagnosis was made on histopathological examination. The clinical and histological features of schwannoma are discussed. A need for early removal of such tumors is recommended to prevent complications.
