The choroidal circulation after retinal detachment surgery.

PURPOSE to assess the effects on choroidal perfusion of scleral buckling and vitrectomy procedures for retinal detachment. METHODS 17 patients were included in the study: 7 underwent scleral buckling and 10 vitrectomy, for rhegmatogenous retinal detachment. pOBF Langham system evaluation was performed before and after surgery (the fellow eye served as control). Statistical analysis was based on paired t-test. RESULTS in the scleral buckling group was found a mean change (SD) of 470 (355.32) microl/min; in the vitrectomy group the mean difference (SD) was 254.2 (132.53) microl/min. In both groups a statistically significant difference with the control was found. CONCLUSIONS our results show that both surgical procedures affect choroidal perfusion and could impair optic nerve head feeding.
