AIM:To evaluate the effectiveness,practicability and safty of using the syringe needles for skin test to outflow the subretinal fluid. ·METHODS:A syringe needle was used for skin test and punctured vertically into the sclera to outflow the subretinal fluid during the surgery.·RESULTS:Totally 41 patients were involved,and 39 patients were successfully outflowed the subretinal fluid for the first time. Two of the patients’ subretinal fluid couldn’t flow out frequently. The incision of sclerocentesis should be enlarged again. There were no severe complications during or after sugery.·CONCLUSION:Using a syringe needle for skin test is a simple and efficient method to outflow the subretinal fluid.
