ODP506 Posterior Staphyloma misdiagnosed as unilateral Grave's ophthalmopathy

Abstract

Abstract 21 year old female presented to our clinic for management of "grave's disease" She was given diagnosis of Graves’ disease three years before presentation to our institution She was treated with PTU for 2-3 months then it was stopped On physical exam On physical exam she has a small diffused goiter Left eye was prominent without chemosis or lid lag Right eye was normal Decreased vision in the left eye, counting fingers only Thyroid function was normal Thyroid receptor antibody was negative Because of decline of vision and unilateral protrusion of Left eye she was referred to ophthalmology for further evaluation. MRI of the Orbits was ordered MRI revealed findings consistent with Staphyloma Staphyloma is a chronic eye condition which results from poor vision if left untreated and causes increase in AP diameter of eye which results in protrusion of eye which might be confused with grave's ophthalmopathy This diagnosis should be considered when patients present with unilateral ophthalmopathy, especially if there is significant decline in vision in the effected eye. Since she presented late in adulthood there is no treatment to improve her vision at this point From the thyroid standpoint she had negative thyroid antibodies and normal thyroid function Ultrasound of thyroid showed thyroid to be diffusely enlarged with homogenous texture Complete eye exam by ophthalmology is indicated in evaluation of ophthalmopathy especially in case of red flags like decreased vison or unilateral presentation With unilateral Ophthalmopathy MRI of the orbits should be part of the workup to exclude other etiologies such as retro-orbital tumors which may be confused with grave's ophthalmopathy. As evident in this case MRI revealed different diagnosis. Presentation: No date and time listed
