Ischaemic Optic Neuropathy - Arteritic

Ischaemic optic neuropathy (ION) is the commonest adult optic nerve disorder encountered worldwide and can be expected to increase in incidence in our ageing population. The condition hasbeen classified as a) anterior (AION) affecting the optic nerve head and b) posterior (PION) involving that portion of the optic nerve behind its immediate retrolaminar portion. 

Further more there are two pathological varieties of the disease c) Arteritic (AAION) almost exclusively associated with Giant CellArteritis (GCA) and d) Nonarteritic (NA-AION or less correctly NAION) usually associated with diabetes, hypertension and hypercholesterolaemia. A recent treatise on the subject runs to more than 600 pages.

Unusual Case of an Orbital Lymphangioma Presenting as Chorioretinal Folds

We report a case of 75-year-old elderly male who presented with diminution and distortion of vision, swelling, pain and upward and nasal deviation of eyes. Computed tomography (CT) scan and magnetic resonance imaging (MRI), fundus photography and optical coherence tomography (OCT) were performed. Amultilocular intraconal cystic mass lesion causing chorioretinal folds wasseen. A presumptive diagnosis of orbital lymphangioma with chorioretinal folds was made and was confirmed by histopathology. This case is being reported because of its unusual presentation in an elderly patient (chorioretinal folds with macular involvement).
