Retinal sensitivity measured with the micro perimeter 1 after resolution of central serous chorioretinopathy.
OBJECTIVE
To examine retinal sensitivity in the macular area of eyes with resolved central serous chorioretinopathy (CSC).


METHODS
Retrospective chart review.


METHODS
We studied retrospectively the medical records of 21 patients (21 eyes) with resolved CSC. Using spectral-domain optical coherence tomography (SD-OCT), 6 x 6-mm areas of macula were examined with 256 sequential horizontal scans. Microperimetry in the macular area was performed with the Micro Perimeter 1 (Nidek, Vigonza, Italy). Seventy-two measurement points were located within the central 10 degrees of the macula.


RESULTS
In eyes with resolved CSC, most OCT images showed a physiologically normal appearance. However, irregularities of the retinal pigment epithelium (RPE) were detected in 11 eyes, and focal defects of the junctions between inner and outer segments (IS/OS) of the photoreceptors were noted in 15 eyes. These abnormalities often were seen within the foveal region. At 983 (79.8%) of 1,232 points with intact retina, retinal sensitivity was 16 decibels (dB) or better. However, a retinal sensitivity of 16 dB or better was obtained at 34.0% of points with irregular RPE and in 20.0% of points with defects of the IS/OS. The mean retinal sensitivities within the area with irregular RPE (13.4 +/- 4.8 dB) or with defects of the IS/OS (11.5 +/- 4.2 dB) were significantly lower than that of intact retina (17.5 +/- 2.4 dB; P < .0001).


CONCLUSIONS
Eyes with resolved CSC often show focal areas with reduced retinal function, which are consistent with irregularity of the RPE or with defects of the IS/OS.
