![]() ![]() I lost my peripheral vision due to a pituitary tumor which compressed my optic chiasm. Laser surgery is a relatively safe procedure with small risk for bleeding, inflammation, eye pressure spike or glare. To assess whether the angles are open or closed and determine if laser surgery is required, an ophthalmologist will perform a comprehensive eye exam. Narrow angles may lead to angle closure glaucoma and laser surgery may lower the risk of developing angle closure. My optometrist has detected narrow angles in my eyes and wants me to have laser surgery to prevent glaucoma. The slow drainage of fluid decreases the internal eye pressure. The fluid is then naturally absorbed by the surrounding tissue. What is this?Īn Ahmed Valve, or glaucoma drainage valve, is a device that is used to help lower intraocular pressure when maximum medical therapy with eye drops and laser treatment is not enough.Ī tube is surgically inserted into the front part of the eye allowing the aqueous fluid from inside the eye to slowly drain through the tube and into the reservoir which is placed on the outside of the eye under the conjunctiva. Her doctor has recommended an Ahmed Valve implant. She has lost one eye, a great deal of her peripheral vision, and has not responded to laser treatment. My mother has had glaucoma for more than 20 years. Because there is no bleb formation, there is no increased risk afterward. IStent insertion is minimally invasive – usually through the cataract incision – and does not increase the risk for infection. The greatest risk of infection after glaucoma surgery is with a trabeculectomy due to bleb formation. Managing dry eyes, blepharitis, and ocular surface disease pre-op may lower your overall risk of infection. Having glaucoma does not increase that risk. The overall risk of infection after cataract surgery is less than 1%. I have glaucoma and need cataract surgery but am worried about the risk of infection. ![]() Studies have been inconclusive and contradictory about an association of sleep apnea with glaucoma progression. But I have not come across any reports on this. A potential issue might be that the pressure of the sleep apnea mask on the face could put undue pressure on the eye and damage the trabeculectomy site. Sleep apnea has no effect on a trabeculectomy. Will a trabeculectomy work if one has sleep apnea? ![]()
