文摘

To define the phenotypic characteristics of the bullous variant of central serous chorioretinopathy (CSC) using multimethod imaging.

Design

Retrospective, observational case series.

Participants

Twenty-one eyes of 14 patients with bullous retinal detachment resulting from CSC (bullous CSC group) and 122 eyes of 84 patients with chronic CSC without bullous retinal detachment (nonbullous CSC group).

Methods

We performed a retrospective review of clinical and multimethod imaging data of patients who sought treatment from the authors with bullous retinal detachment resulting from CSC between January 2010 and November 2015. Multimethod imaging comprised color photography, fluorescein angiography, fundus autofluorescence, and high-resolution optical coherence tomography. Consecutive cases of chronic CSC without bullous retinal detachment, seen during the same period, comprised a comparative group.

Main Outcome Measures

Qualitative and quantitative characteristics of the choroid, retinal pigment epithelium, and retina were compared between the 2 groups.

Results

Mean age of the bullous CSC group was 53.8 years. There was no difference in age, visual acuity, corticosteroid use, or the proportion of white patients and men between the 2 groups (all P > 0.132). Peripheral nonperfusion occurred only in eyes with bullous retinal detachment (38% of cases). Retinal pigment epithelial tears were seen in 95% of eyes in the bullous group and none of the eyes in the nonbullous CSC group. The bullous CSC group demonstrated a greater number of pigment epithelial detachments (PEDs) and more eyes demonstrated PEDs with internal hyperreflectivity (both P < 0.016). Mean subfoveal choroidal thickness in the bullous CSC group (463.1±83.1 μm) was not different compared with that of the nonbullous CSC group (400.6±100.6 μm; P = 0.993). More eyes in the bullous CSC group demonstrated hyperreflectivity around large choroidal vessels and at the level of the choriocapillaris on OCT (P < 0.001). Retinal folds and subretinal fibrin were identified in a greater proportion of eyes in the bullous CSC group (both P < 0.001).

Conclusions

Bullous retinal detachment is a rare manifestation of chronic CSC and is characterized by a unique constellation of phenotypic and multimethod imaging features.
