Correlation of Retinal Sensitivity and Retinal Thickness in Central Serous Chorioretinopathy

Aim: To evaluate the correlation of microperimetry (MP) and optical coherence tomography (OCT) in eyes having acute onset of central serous chorioretinopathy (CSCR). Methods: After a detailed ophthalmological examination, all cases were evaluated by fundus fluorescein angiography, OCT and MP. Mean macular thickness was detected by OCT. Mean macular sensitivity (MS) and mean defect (MD) were determined by MP. The correlation between OCT and MP findings was analyzed by Spearman’s correlation test. Results: Fifteen eyes with CSCR of 15 patients with a mean age of 40.5 ± 6.7 years were recruited. The mean visual acuity was 0.7 ± 0.2, and the mean macular thickness was 348.9 ± 75.8 μm. Mean MS and MD were 13.9 ± 4.6 and –5.2 ± 4.1 dB, respectively. The mean macular thickness was significantly correlated with both mean MS and MD (p = 0.011 and p = 0.017, respectively). A significant correlation was also found between mean macualt thickness, MS and MD in the central 1 mm, superior 3 mm and nasal 3 mm of the macula (p < 0.05). Conclusions: Our results demonstrated a significant correlation between structural and functional changes in CSCR. MP provides quantitative measurements of central macular function in CSCR that may supplement OCT findings as well as the better understanding of visual functions during the acute stage of the disease.
