Summary
Fundus autofluorescence (FAF) changes in chronic central serous chorioretinopathy (CSC) correlate with visual acuity and retinal sensitivity, as measured by microperimetry. This confirms FAF
Area of Science:
- Ophthalmology
- Retinal Imaging
- Visual Electrophysiology
Background:
- Chronic central serous chorioretinopathy (CSC) is a condition affecting the macula.
- Morphologic changes in CSC can impact visual function.
- Fundus autofluorescence (FAF) provides insights into retinal pigment epithelium health.
Purpose of the Study:
- To investigate correlations between macular morphologic changes seen on FAF and functional parameters in chronic CSC.
- To assess the relationship between FAF imaging and microperimetry (MP) findings.
Main Methods:
- A prospective, cross-sectional study involving 46 eyes from 39 patients with chronic CSC.
- FAF imaging and microperimetry (MP) were performed on all participants.
- Retinal sensitivity maps from MP were superimposed onto FAF images to analyze relationships.
Main Results:
- Best-corrected visual acuity (BCVA) showed a significant correlation with FAF findings (P < .0001).
- A concordance of 0.720 (Cohen's kappa = 0.456) was found between FAF and MP evaluations.
- Hypo-autofluorescent areas on FAF corresponded to decreased retinal sensitivity, while absolute scotomas correlated with absent autofluorescence.
Conclusions:
- Altered FAF patterns in chronic CSC patients are functionally correlated with microperimetry results.
- FAF changes significantly impact retinal sensitivity, reflecting functional impairment in chronic CSC.
- FAF is a valuable tool for assessing visual function deficits in chronic CSC.
