A PRELIMINARY STUDY OF SHORT-TERM EFFICACY OF Nd:YAG LASER PERIPHERAL IRIDOTOMY IN PATIENTS WITH PRIMARY ANGLE CLOSED GLAUCOMA

摘要

Q-switched Nd:YAG laser was used for the peripheral iridotomy in 68 cases(80 eyes) of primary angle closed glaucoma. The average number of laser shots is 20.5(1～127 shots), and the average shot energy is 2.5 mJ(0.9～5.6mJ). The successful rate of iris penetration is about 97.6%. The size of the iris hole is not smaller than 0.2mm~2. The kind of the iris is the most important factor that causes the marked variation in laser shots and in laser shot energy. The main complications of Nd:YAG laser iridotomy p...
