January is Glaucoma Awareness Month, and in this month we dive into aspects of glaucoma care to help our patients. To learn more about general facts about glaucoma, please refer to the article from 2024. In this post, we will touch on the different types of treatments available for glaucoma. In glaucoma, eye pressure damages the optic nerve and leads to irreversible vision loss. The goal of glaucoma treatment is to lower the eye pressure. This can be accomplished in several ways: eye drops, procedures, and surgeries. Each has its advantages and disadvantages. The treatment of glaucoma is highly personalized and different treatments apply to different patients. The most straightforward and often first line treatment of glaucoma involves the use of eye drops . There are multiple classes of eye drops, and each has its own set of side-effects that are taken into account when providing recommendations to patients. Eye drops are typically used anywhere from one to three times daily. As glaucoma advances, the eye pressure may respond less well to eye drops and require additional treatments, such as procedures or surgeries. Procedures for glaucoma involve lasers and injections. Laser treatment varies depending on the type of glaucoma. The most common form of glaucoma, termed open-angle glaucoma, occurs when the natural drain in the eye does not function well. One cause of this poor function occurs due to a clogging of the natural sieve that filters out the fluid in the eye, called the trabecular meshwork. For this form of glaucoma, a laser may be used to clean this sieve, a procedure called trabeculoplasty. Trabeculoplasty has been in use for decades, supported by a well established scientific literature. In fact, it is now recommended as first line therapy in many instances. The second form of glaucoma, angle-closure glaucoma, occurs when the natural drain is blocked. A different laser procedure, called an iridotomy, attempts to relieve this blockage. A relatively new procedure involves the injection of a medication into the eye , whereby it slowly dissolves over a period of months. This injection effectively acts as a substitute for an eye drop and may be beneficial in patients who do not tolerate eye drops well. Sometimes, eye drops and procedures are not enough to control the eye pressure, and the eye remains at risk of vision loss. In these cases, surgery may be required. Surgery can be divided into minimally invasive glaucoma surgeries (MIGS) and traditional surgeries. MIGS, often performed at the time of cataract surgery, try to rehabilitate the natural drain in the eye. These involve the use of stents and other instruments to open the natural drain. Sometimes, even these surgeries are not enough, and the use of traditional surgeries is required. In these cases, the natural drain cannot be rehabilitated, and a bypass procedure is performed, whereby a tiny window is created in the eye to allow the fluid to exit the eye and lower the eye pressure. There are two variants of this procedure: in one, the tiny window is created and left as is, and in the other, a small tube is inserted into the tiny window. The treatment of glaucoma has evolved over many years and now encompasses a wide variety of therapies that allow for a personalized approach. And fortunately, for the great majority of patients, appropriate treatment can slow or stop the progression of glaucoma. If you have any questions or concerns about glaucoma or its treatment, we here at the Glaucoma Center at NJ Eye and Ear, consisting of myself, Dr. Khelly Savant, Dr. Nahndi Bush , and Dr. Daniel Stegman , are always available to assist you in making decisions regarding your glaucoma care.
