One use for a YAG laser in surgery is to punch a hole in the iris to relieve increased pressure within the eye from acuteangle-closure glaucoma. In this type ofglaucoma, there is a sudden (acute) increase in pressure in theanterior(front) chamber of the eye due to abrupt blockage of t...
结论:Nd:YAG激光虹膜切开术是治疗葡萄膜炎继发性青光眼的一种安全有效的方法,能避免此类患者房角永久性粘连.%AIM:To evaluate the value of Nd: YAG laser iridotomy in glaucoma secondary to uveitis. METHODS:Totally 35 eyes of 35 patients with glaucoma secondary touveitis were treated by Nd: YAG laser...
ABSTRACT Objective: To observe the clinical curative effect of YAG laser posterior vitreous cortex (PVC) incision and drainage under sedation on neonatal preretinal hemorrhage in macular area. Methods: Forty-five neonates (46 eyes) with preretinal hemorrhage in macular area were enrolled and underwent...
Laser sclerostomy may offer better results than repeat trabeculectomy in eyes that have undergone prior filtering surgery.74 Perforation of the sclera in the area of the chamber angle to create a filtering sclerostomy has been successfully performed with the Nd:YAG laser, the dye laser,75 the ...
Nd:YAG laser This type of laser is often used for the treatment of hyperpigmentation and dark circles under the eyes. TheNd:YAG laseremits energy into the skin, which is absorbed by the melanin and breaks it down, resulting in a reduction of dark circles and hyperpigmentation.78 ...

Results Fifty-two patients (52 eyes; 17 men and 35 women; 51 white and 1 Asian) with symptomatic Weiss rings were enrolled in the study (mean [SD] age, 61.4 [8.0] years for the YAG laser group and 61.1 [6.6] years for the sham group). The YAG laser group reported greater symptomat...
retina can occur independently as a result of age. In predisposed eyes, these changes could rarely be precipitated by a laser procedure. Such changes would usually be treatable. Most important of all, use of the YAG laser avoids other risks specific to actual surgery (e.g. bleeding or ...
Results All cases showed no decrease in vision after 1 week after treatment, no significant increase in intraocular pressure after 1 hour and1 week after surgery, 71 eyes were significantly alleviated or disappeared from floaters. There were still floating objects in the eyes, but the reduction ...
Decreased intraocular pressure (IOP) was noted in most eyes after Nd:YAG laser iridotomy; only 10 eyes required further filtration surgery. Visual acuity was unchanged or improved in 97.9% of all eyes at the 6-month visit. Cataract progression was primarily responsible for those eyes with ...
