Purpose To evaluate the safety and efficacy of draining subretinal fluid with transchoroidal probing by using the traditional needling and diode endolaser probing. Methods The investigation included 70 consecutive patients(74 eyes) with rhegmatogenous retinal detachment undergoing scleral buckling surgery.Seventy cases were randomly divided into 2 groups,group A 34 cases(36 eyes)with the needle drainage procedure and group B 36 cases(38 eyes) with the diode probe respectively.The safety and efficacy were compared in between the 2 groups. Results No operative failure was found in these 2 groups.In group A,subretinal hemorrhage occurred in 3 eyes,and retinal incarceration,retinal preforation in one eye. No significant complication occurred in group B. Conclusion Diode laser drainage has the advantage in that it may reduce the incidence of operative complication with drainage.This technique might be used in any case requiring drainage of subretinal fluid especially of rhegmat　ogenous retinal detachment in cases of shallow retinal detachment. (Chin J Ocul Fundus Dis,1998,14:202-203)
