Purpose: To compare the clinical features, treatments, and outcomes between bullous and chronic variants of central serous chorioretinopathy (CSC).

Design: Retrospective, observational case series.

Participants: Sixty-two eyes of 44 patients with bullous-variant CSC (bvCSC) and 97 eyes of 85 patients with nonbullous CSC.

Methods: We conducted a national survey between September 1, 2020, and March 31, 2021, of members of the Korean Retina Society and obtained data of patients with bvCSC from 11 retinal centers. A comparator group comprised consecutive chronic CSC patients without bullous detachment.

Main outcome measures: Baseline demographics and patient characteristics were compared between groups. Secondary outcomes included factors associated with visual prognosis within the bvCSC group.

Results: Compared with the nonbullous CSC group, the bvCSC group presented at a younger age (49 vs. 52 years; P = 0.047) and with more bilateral involvement (41% vs. 14%; P < 0.001). Systemic corticosteroid use was more prevalent in the bvCSC group, both in terms of any exposure (50% vs. 20%; P = 0.001) and long-term exposure (36% vs. 9%; P < 0.001). The bvCSC group had distinct imaging features (all P < 0.05): retinal folding (64% vs. 1%), subretinal fibrin (75% vs. 13%), multiple retinal pigment epithelium tears (24% vs. 2%), and multifocal fluorescein leakages with terminal telangiectasia (36% vs. 1%). Although bvCSC patients had worse vision at diagnosis (20/80 vs. 20/44; P = 0.003), treatment response was more robust (fluid resolution by final follow-up, 84% vs. 68%; P = 0.034) even with conservative management, resulting in similar final vision (20/52 vs. 20/45; P = 0.52). History of kidney-related (odds ratio [OR] 5.4; 95% confidence interval [CI] 1.3-18.5; P = 0.045) and autoimmune/rheumatoid diseases (OR 25.4, 95% CI 2.8-195.0; P = 0.004) showed associations with the bvCSC group. Apart from vision at diagnosis (OR 0.1, 95% CI 0.05-0.36; P < 0.001), a history of renal transplantation was most predictive of visual prognoses for bvCSC eyes (OR 0.2, 95% CI 0.04-0.75; P = 0.020).

Conclusions: Bullous-variant CSC may be associated with pathogenic risk factors based on underlying medical conditions and systemic corticosteroid use. Poor vision at diagnosis and history of renal transplantation were associated with poor visual outcome.
