Posterior scleritis is a granulomatous inflammation occurring either within the scleral tissue or in the vascular networks adjacent to it. This inflammatory process can cause leakage of fluid from the choroid into the suprachoroidal space leading to ciliochoroidal effusion and an exudative retinal detachment. The following is a case report of a 64 year old white male, who presented with an acute angle closure attack and myopic shift in one eye, and later developed an exudative choroidal and retinal detachment. Posterior scleritis was diagnosed based on ultrasonography and the orbital CT scan findings. The acute angle closure attack, myopic shift and exudative detachments completely resolved with the use of oral steroids and cycloplegics.
