Bilateral Adie's Tonic Pupil and Hyperopic Shift in Idiopathic Sclerochoroidal Calcification

Sclerochoroidal calcification is a rare but recognised ophthalmic manifestation seen mostly in elderly Caucasian individuals. The lesions, often bilateral, appear as yellow-white irregular subretinal lesions usually found along the mid-peripheral fundus. Though typically asymptomatic, sclerochoroidal calcification has rarely been associated with parafoveal involvement, choroidal neovascularisation, and serous detachment of the calcifications. Visual involvement is typically minimal, and neovascularisation is often visually insignificant. We present a rare case of sclerochoroidal calcification in a 64-year-old Caucasian female who presented with painless progressive bilateral vision loss and a hyperoptic shift with subsequent development of bilateral sequential Adie's tonic pupil. To the best of our knowledge, this is the first such report in the English language literature.
