Macular Integrity Assessment and Fixation Analysis in Chronic Central Serous Chorioretinopathy

Abstract EN

Purpose.

To investigate retinal sensitivity characteristics associated with morphologic changes in the eyes exhibiting chronic central serous chorioretinopathy (CSC), using macular integrity assessment (MAIA) microperimetry.

Methods.

A retrospective, cross-sectional, observational study was constructed.

The eyes of patients classified as chronic CSC, according to the onset of subjective symptoms with serous retinal detachment, as confirmed by optical coherence tomography examination, were included in the study.

Retinal sensitivity and fixation were analyzed by performing microperimetry examinations using the MAIA instrument.

Results.

We reviewed microperimetry examinations of 15 eyes of 15 patients (age: 28–51 years) with chronic CSC and mean best-corrected visual acuity of −0.2 logMAR units.

The mean retinal integrity in the chronic CSC group was 49.0 ± 27.6, which was significantly different from the control eyes.

The mean average threshold in the eyes with chronic CSC was 24.7 ± 5.8 dB, which also was significantly different from the control eyes.

Fixation stability was significantly different between the CSC and control eyes for the P1 parameter (90.1 ± 13.7 versus 99.3 ± 1.5), and for the P2 parameter (97.4 ± 4.0 versus 100.0 ± 0.0).

Conclusion.

New microperimetry technology may provide valuable information regarding the visual status of chronic CSC cases.

Our findings suggest that retinal sensitivity and fixation stability in chronic CSC eyes may serve as useful indicators for assessing the effectiveness of clinical treatments.
