Abstract

A young woman presented with acute onset diminution of vision, painful ocular movements in LE, and binocular diplopia since 10 days. Examination revealed Visual Acuity(VA) of 20/240, mild proptosis 3 mm, limitation on down gaze and RAPD with no signs of inflammation. Fundus revealed multiple bilateral disc drusen. ENT examination was normal. Suspecting orbital cysticercosis/leaking demoid/ orbital cellulitis MRI was ordered which revealed abscess of posterior aspect of Superior Rectus (SR) muscle. A diagnosis of pyomyositis of superior rectus causing retrobulbar neuritis was made. IV antibiotics were administered. VA, diplopia improved with mild residual restriction of down gaze at 4 weeks and grade 1 RAPD. Serial USG B scan revealed decreasing size of abscess. This case demonstrates a rare occurrence of superior rectus abscess causing retrobulbar neuritis which resolved with intravenous antibiotics alone. Pyomyositis should also be considered when there is painful limitation of extraocular movements.
