2020年5月5日 · Laser peripheral iridotomy is the standard first-line treatment in closed-angle glaucoma and eyes at risk for this condition. Laser peripheral iridotomy has been used since 1984 both as treatment and prevention of the disease.

Ophthalmologists perform laser iridotomy to alleviate eye pressure that threatens to cause long-term vision loss. The surgery takes only a few minutes, and its purpose is to minimize the development of glaucoma, the second-leading cause of blindness.

2024年10月10日 · Laser iridotomy is a surgical treatment for closed-angle and narrow-angle glaucoma. It uses a laser beam to create a small hole in the iris. This allows eye fluid to flow regularly and lower eye pressure.

2024年1月12日 · Laser iridotomy, also known as laser peripheral iridotomy or laser PI, is performed to widen the drainage angles for patients with narrow angles or angle closure glaucoma. The laser reduces the risk of developing high eye pressure due to a closed angle, which in turn reduces the risk of further optic nerve damage from glaucoma.

A laser iridotomy may be a preventative step for patients with anatomically narrow angles or treatment for angle-closure glaucoma. A laser iridotomy creates a small opening in the iris to free fluid trapped behind the iris, pushing it forward and potentially closing the drainage angle.

Several types of lasers can be used to treat pupillary-block glaucoma. The use of the argon laser to create an iridotomy was accepted widely by 1980. Since then, another type of laser, the neodymium: YAG laser, also has proven to be safe and effective.

Laser iridotomy is mainly used to try to: after the pressure in the affected eye has been reduced with medicine or when medicines fail. and those people who have had closed-angle glaucoma in their other eye. Laser iridotomy may prevent further …

2022年12月2日 · Laser iridotomy is a procedure used to treat acute-closed angle glaucoma. A laser cuts a hole in the iris to drain fluid out of the eye and restore normal pressure levels. Learn more about laser iridotomy.

2023年8月1日 · Iridotomy, often referred to as laser iridotomy, is a surgical procedure aimed at treating certain types of glaucoma and other eye conditions that cause an abnormal increase in intraocular pressure (IOP).

2024年7月5日 · Laser Peripheral Iridotomy (LPI) is a procedure that uses a laser to create a small hole in the iris to improve the flow of fluid within the eye and prevent or treat certain eye conditions. Indications for LPI include narrow angles, angle-closure glaucoma, and prevention of acute angle-closure attacks.
