Plasma cerebellin levels in patients with central serous chorioretinopathy.

PURPOSE

To evaluate levels of plasma cerebellin, cortisol, adrenaline and noradrenaline in patients with central serous chorioretinopathy (CSC).

MATERIALS AND METHODS

This prospective study included 30 patients diagnosed with acute CSC (Group 1) and a control group of 30 age-matched, healthy subjects without CSC (Group 2). Levels of plasma cerebellin, cortisol, adrenaline and noradrenaline were examined in blood samples taken after 8-12hours of fasting. A value of p<0.05 was considered statistically significant in the comparative analyses.

RESULTS

The mean plasma cerebellin level was found to be 232.56±113.28 pg/ml in Group 1 and 174.07±82.04 pg/ml in Group 2 (p=0.02). Mean plasma cortisol was 13.19±3.87μg/ml in Group 1 and 9.55±2.92μg/ml in Group 2 (p<0.01). Mean plasma adrenaline was 60.62±26.67 pg/ml in Group 1 and 46.17±19.20 pg/ml in Group 2 (p=0.03). Mean plasma noradrenaline was 206.66±73.90 pg/ml in Group 1 and 149.96±51.36 pg/ml in Group 2 (p<0.01).

CONCLUSION

It can be concluded that increased cerebellin may have a role in the etiology of CSC by increasing catecholamine expression from the adrenal medulla and indirectly by increasing cortisol levels via a paracrine effect from the adrenal cortex.
