Abstract
The purpose of the current study was to investigate the association between visual function and retinal structure in central serous chorioretinopathy (CSC). In 22 eyes of 22 chronic CSC patients with serous retinal detachment at the macula, retinal sensitivity was measured using MP3 microperimetry (NIDEK, Japan) and mean sensitivity within two degrees (MS2), four degrees (MS4) and six degrees (MS6), as well as foveal sensitivity (MS0), were calculated. Retinal structure was measured using optical coherence tomography (OCT, Spectralis, Heidelberg). The relationship between visual function (LogMAR best-corrected visual acuity [LogMAR VA] and MS0, MS2, MS4, MS6) and serous retinal detachment height at the fovea (SRDH), central retinal thickness (CRT), macular volume (MV) and central choroidal thickness (CCT) was investigated. There were significant negative correlations between LogMAR VA and MS0 (p = 0.016), MS2 (p = 0.049). No significant relationship was observed between LogMAR VA and SRDH (p = 0.97) although there was a significant negative correlation between SRDH and MS2 (p = 0.028), MS4 (p = 0.049), MS6 (p = 0.023). In conclusion, in CSC, serous retinal detachment was significantly correlated with retinal sensitivity measured with MP3, but not with LogMAR VA.

Japan) and mean sensitivity within two degrees (MS2), four degrees (MS4) and six degrees (MS6), as well as foveal sensitivity (MS0), were calculated
Previous studies have highlighted the usefulness of this type of perimetry[16,17,18,19,20,21,22,23,24,25,26,27], but all these studies used microperimetry to evaluate the effects of treatment interventions on macular retinal sensitivity in a relatively short period after the treatment, and to date, no study has revealed the usefulness of retinal sensitivity with microperimetry in chronic Central Serous Chorioretinopathy (CSC)
MP-3 visual field (VF) testing and Spectral domain (SD)-optical coherence tomography (OCT) were measured in patients with CSC
Summary
Japan) and mean sensitivity within two degrees (MS2), four degrees (MS4) and six degrees (MS6), as well as foveal sensitivity (MS0), were calculated. In CSC, serous retinal detachment was significantly correlated with retinal sensitivity measured with MP3, but not with LogMAR VA. Microperimetry, known as fundus related perimetry, is a type of visual field (VF) test that enables the detailed assessment of macular retinal sensitivity. Previous studies have highlighted the usefulness of this type of perimetry[16,17,18,19,20,21,22,23,24,25,26,27], but all these studies used microperimetry to evaluate the effects of treatment interventions on macular retinal sensitivity in a relatively short period after the treatment, and to date, no study has revealed the usefulness of retinal sensitivity with microperimetry in chronic CSC. It is of interest to investigate the degree of correlation between structural change and VA or MP-3 sensitivity measurements in chronic CSC patients.
