·AIM:To evaluate the effect of 532nm frequency-doubled laser in treating retinal holes.·METHODS:Totally 52 patients 62 eyes with retinal holes were treated with 532nm frequency-doubled laser.Whether retinal holes be sealed were observed.·RESULTS:After 6-24 months,50 patients 60 eyes with retinal holes were sealed(96%),2 patients 2 eyes occurred retinal detached and were treated with cryoretinopexy and sclera buckling.·CONCLUSION:Sealing retinal holes with 532nm frequency-doubled laser is an effective,safe,convenient and economical way.·
