Purpose:

To predict the changes in visual-acuity and macula after treatment by analyzing four bands, external limiting membrane(ELM), inner and outer segments(IS/OS), cone outer segment tips (COST), retinal pigment epithelium (RPE) in central serous chorioretinopathy using optical coherence tomography (OCT) before and after treatment.

Method:

The retrospective study consisted of 31 eyes of 29 patients with central serous chorioretinopathy. The relation of the four bands of macula and visual-acuity were assessed by OCT before and after treatment in all of those eyes.

Result:

Out of the four bands analyzed, only the band 3 (COST) showed significant changes (p<0.05). From the 31 eyes tested, the Band 3 (COST) disappeared in ten eyes, eleven eyes didn’t recover from the Band 3 (COST), six eyes showed no change, while four eyes developed the Band 3 (COST) after originally showing no signs. Furthermore, Out of the ten eyes which band three (COST) disappeared from, 70% had a defect band 4 (RPE) before treatment. Among the eyes which didn’t recover from the Band 3 (COST), 45% had this defect. 25% of the eyes which recovered from band 3 (COST), had a defect band 4 (RPE) before treatment. While the eyes which showed no change in the third band, showed no signs of defect band 4 (RPE) before treatment. In relation to the band 3 (COST) and visual-acuity, 5 out of the 21 eyes which disappeared or didn’t recover from band 3 (COST), the visual-acuity became worse. Whereas, in the cases which recovered or showed no changes from the band 3 (COST), the visual-acui ty remained the same.

Conclusion:

When comparing the before and after treatment in central serous chorioretinopathy, statistically, the changing of band 3 (COST), was related with visual-acuity whether or not the band 4 (RPE) was intact. In conclusion, the recovery or sustaining of the band 3 (COST) and the existence of band 4 (RPE) before treatment are considered helpful in predicting the improvement of visual-acuity.
