Dr. Asra SalehaJR3 ophthalmologyIGGMC Nagpur
U/L painless proptosis – varied causes
Multiple myelomamalignancy of reticuloendothelial cells not an uncommon conditionBut orbital involvement rare
Multiple myeloma presenting as U/L painless proptosis is rare
Case reportA 55-year-old-man presented with painless progressive unilateral right sided proptosis with restricted ocular movements of 60 days duration. He also had history of chronic lower back pain , further examination suggested of localised painless anterior chest swelling .DD

Presentation of the right eye after chemo therapy.
Discussion In Multiple myeloma metastasis of the
orbit is a rare, but a serious condition. Involvement of almost every ocular structure has been reported . Most common clinical presentation includes proptosis, redness, pain, diplopia, and decreased vision. Unilateral involvement of one eye is not uncommon. It is argued that myelomatous changes of the orbit are common, even though clinical presentation is extremely rare .
Discussion Solitary extramedullary orbital plasmacytoma
as an initial presenting feature in a multiple myeloma patient has also been reported. In most of the cases reported, CT scan was the imaging modality of choice. Treatment options include systemic chemotherapy and local radiation and often good response to these options is noted . Our case is unique because of its dramatic presentation as seen in the images and quick resolution of the symptoms after a very short duration of chemotherapy
