PROGNOSIS EVALUATION WITH OPTICAL COHERENCE TOMOGRAPHY IN CHRONIC CENTRAL SEROUS CHORIORETINOPATHY.

BACKGROUND: Central serous chorioretinopathy (CSCR) is the fourth most common retinopathy that causes severe vision loss and is frequently seen in young and active patients. Our aim in this study is to evaluate whether a foresight about the prognosis of patients with CSCR can be obtained by optical coherence tomography (OCT) findings.

MATERIALS AND METHODS: Patients diagnosed with chronic CSCR at Fatih Sultan Mehmet Research and Training Hospital, Ophthalmology Department, were screened between January 2017 and September 2019, and 30 patients were included in the study. The anatomical and functional changes of the patients during the 6-month follow-up and the relationship between the OCT findings at baseline and the best corrected visual acuity (BCVA) in the sixth month were evaluated.

RESULTS: All of the participants were treated with subthreshold micropulse laser therapy. BCVA increased significantly at first month and sixth month examinations compared to baseline, while the central macular thicknesses decreased significantly (p=0.01, p=0.00). Among the parameters examined in the baseline OCT, a positive correlation was found between the thickness of the outer nuclear layer (r=-0.520, p=0.003) and BCVA at sixth month. In addition, subretinal fluid density and the number of intra-subretinal hyperreflective dots negatively affected BCVA (r=0.371, p=0.044 and r=0.509, p=0.004).

CONCLUSION: Outer nuclear layer thickness, subretinal fluid density and intra-subretinal hyperreflective dots were the OCT biomarkers related to sixth month BCVA. The clinical use of these biomarkers will help evaluate the prognosis of the CSCR.
