[Efficacy of argon and Nd:YAG laser combined in the treatment of primary chronic closed-angle glaucoma]. 
22 cases (29 eyes) of primary chronic closed-angle glaucoma were treated with Argon laser gonioplasty (ALG) and Nd:YAG laser iridectomy.  Among 8 eyes in which the closed-angle was not opened by ALG, Nd:YAG laser gonioplasty was added, and 6 eyes became successful.  For 9 eyes in which the IOP failed to drop inspite of the opened anterior chamber angle, Argon laser trabeculoplasty was added to bring remarkable curative effects to 7 eyes.  During a follow-up of 5 to 14 months, 25 eyes (86%) obtained satisfactory results.
