Purpose: To evaluate the correlation between foveal thickness, as measured with optical coherence tomographic evaluation, and the visual acuity in patients who suffered from unilateral resolved central serous chorioretinopathy.
Methods: Twenty-eight consecutive patients who were diagnosed with unilateral resolved central serous chorioretinopathy were studied. High-resolution optical coherence tomography was performed on all of the patients. The foveal thickness of the involved eye was normalized by dividing its thickness with that of the uninvolved eye. The best-corrected visual acuity of the involved eye was normalized as well. The subjects were divided into two groups according to the minimum value of the normalized foveal thickness in the 22 healthy subjects.
Results: The mean foveal thickness was 128.68±22.06 ?m in the involved eyes and 148.18±13.88 ?m in the uninvolved eyes. There was a statistically significant correlation between the normalized foveal thickness and the normalized visual acuity. There were statistically significant differences in the normalized visual acuity and the duration of the symptoms between the group with foveal thickness above the minimum value and the group with foveal thickness below the minimum value.
Conclusions: There was a statistically significant correlation between foveal thickness and visual acuity. The patient group with a foveal thickness value above the minimum value of the normalized foveal thickness showed a statistically significant improvement in visual acuity and a shorter duration of symptoms. It seems that the foveal thickness is associated with visual acuity and the duration of symptoms.
