What is Glaucoma?
Glaucoma is a collective group of diseases which harm the optic nerve and can lead to vision impairment and blindness. The optic nerve is a bundle of more than one million nerve fibers which connects the retina to the brain. Open-angle glaucoma is the most common type of glaucoma which initially has no symptoms and no pain and even the vision stays normal. It can be developed either in one eye or both eyes. Depending on the type of glaucoma a patient has, several treatment options may be considered. The non-surgical options include eye medications such as glaucoma eye drops or even oral medications in the form of pills. Even though most glaucoma cases can be managed and treated with few drugs, a few patients might require surgical intervention to lessen the intraocular pressure (IOP) to a safe level by enhancing the leakage of drainage of fluids. At times, surgical procedure can alleviate the need for glaucoma eye drops. Nevertheless, one might have to continue with the drops even post surgery.
Few studies done on the glaucoma surgery device market indicate that a laser procedure called selective laser trabeculoplasty (SLT) might be almost as efficient as glaucoma eye drops for reducing the eye pressure on the inside. The laser surgery might be regarded as an initial treatment, specifically for people who have difficulty to follow a rigorous, regular schedule for putting eye drops. An additional procedure termed as trabeculectomy generates an artificial drainage area. This procedure is used in advanced glaucoma cases wherein the damage to the optic nerve has taken place and the intraocular pressure continues to increase. The last common option is a shunt, which is a glaucoma surgery device that a surgeon implants in the eye to improve the fluid drainage. Glaucoma surgical procedures are constantly evolving and several new devices which are under analysis into the market have been persistent and continued the trend towards escalating safety, reduced surgical treatment and use of existing physiologic paths.
