Lagophthalmos and Ptosis in Inclusion Body Myositis.

ABSTRACT

Sporadic inclusion body myositis is the most commonly acquired type of idiopathic inflammatory myopathy in people aged 50 and above. There is early weakness and atrophy of forearms and quadriceps and a third of patients also have mild facial weakness. Extraocular muscles are not affected and ptosis is rarely seen. The authors describe a unique case in which inclusion body myositis presented with early mid face weakness and atrophy resulting in unilateral lagophthalmus, and ptosis, which have not been documented before. This case is not only unique in its presentation but also emphasizes the importance of considering differential diagnoses and conservative measures before contemplating surgery.
