[Central serous chorioretinopathy--retinal function and morphology: microperimetry and optical coherence tomography]. / Chorioretinopathia centralis serosa--Netzhautfunktion und -morphologie: Mikroperimetrie und optische Kohärenztomografie im Vergleich.

ABSTRACT

BACKGROUND: The purpose of this study was to evaluate and compare retinal function and morphology in patients with central serous chorioretinopathy (CSC) using fundus perimetry and optical coherence tomography (OCT). PATIENTS AND METHODS: In 14 eyes of 14 patients with unilateral and first manifestation of CSC, fundus perimetry with the Microperimeter 1 (MP1) as well as OCT were carried out. The average retinal thickness and the average differential light threshold of the corresponding visual field were analyzed. RESULTS: All patients presented a serous detachment of the central neurosensory retina with a maximal retinal thickness of 381+/-82 microm. The microperimetric examination revealed on average a mean defect of 8.3+/-3.8 dB, which showed a good correlation to retinal thickness (r=0.73). Likewise, maximal retinal thickness and mean threshold values in the corresponding visual field displayed a good correlation (r=-0.58). CONCLUSION: The MP1 enables quantification of functional defects in patients with CSC. Although visual acuity was only slightly reduced, all patients showed extensive scotomata in fundus perimetry, which correlated well with retinal thickness.
