Surgical Treatment of Bullous Exudative Retinal Detachment Secondary to Atypical Bilateral Central Serous...

This study aimed to report the diagnostic process, treatment, and follow-up of a patient with bullous exudative retinal detachment (RD) associated with an atypical variant of bilateral central serous chorioretinopathy (CSCR). A 28-year-old woman was referred to our clinic for total bullous RD in the right eye with a vision level of light perception only. She had been previously diagnosed with idiopathic uveal effusion syndrome and treated with systemic corticosteroid therapy with no response, and was referred to us for scleral window surgery. Four-quadrant scleral window surgery with external drainage of the subretinal fluid was performed, resulting in a transient partial attachment of the retina. RD started to progress again within 3 weeks, which prompted comprehensive imaging together with more advanced systemic workup for systemic lupus erythematosus and other rheumatological and immunological diseases. Systemic corticosteroid therapy was initiated during this period but did not stop the progression and was discontinued after a short time. Fluorescein angiography and indocyanine green angiography revealed multifocal choroidal leakage foci and large choroidal vessels without any intraocular inflammation findings and led to the diagnosis of atypical CSCR. Pars plana vitrectomy (PPV), internal drainage of the subretinal fluid, endolaser to the focal leakage areas, and intravitreal aflibercept injection were performed. Visual acuity increased to 0.8 within 8 months after the surgery with no recurrence. Bullous exudative RD is a very rare and atypical form of CSCR, and a favorable outcome can be obtained with PPV and surgical drainage of subretinal fluid followed by laser photocoagulation.
