With a patient’s sight on the line, glaucoma is a race against time. For every increase in intraocular pressure (IOP), a person with glaucoma slowly inches her way towards blindness. A glaucoma specialist therefore must address this process by keeping her patient’s eye pressure level at normal or low-normal levels. Fortunately, a wide range of glaucoma treatment options are available nowadays, from simple eye drops to procedures such as laser ablation, invasive surgeries such as trabeculectomy, to the more recent and less invasive ones like canaloplasty.

Glaucoma Treatment Options

Glaucoma Treatment Options

Glaucoma Drops have evolved from miotics (pilocarpine), carbonic anhydrase (dorzolamide), beta blockers (timolol), alpha agonists (brimonidine), to prostaglandin analogs (latanoprost, travoprost) and various combinations of these.  Although many of these drugs have been used as glaucoma treatments for decades, patients who are sick or elderly, who have existing systemic diseases like diabetes, asthma, heart blocks, may experience significant side effects with glaucoma drop treatment.  Issues such as compliance can also be a challenge for doctors and their caregivers due to the inconvenience of applying the medication several times in a day.  Moreover, because of the above mentioned issues with topical therapy, many glaucoma patients eventually resort to glaucoma surgery or other invasive procedures such as laser trabeculoplasty.

Laser One of the alternatives to using glaucoma eye drops is Laser Trabeculoplasty (LT). Unlike drugs, laser has no systemic side effects. This makes it well suited for high risk patients who are either too ill or too old to undergo surgery or tolerate medical treatment. Laser technology creates small burns in the anatomical part of the eye responsible for draining the aqueous fluid, thereby increasing outflow and decreasing intraocular pressure. It can be likened to clearing debris from the drain in order to relieve a clogged sink.  Although studies have shown that LT is as effective than medication alone, it is known to lower IOP only temporarily and has a high failure rate. In one study, half of the patients who had previous LT eventually underwent the filtering surgery (trabeculectomy) after five years.

Glaucoma Surgery Trabeculectomy, the classic and oldest among filtering surgery is considered to be the “gold standard” with regard to maximally reducing IOP. It requires creation of a fistula to drain the excess aqueous fluid. Although there have been various permutations of the procedure over the years, ranging from implantation of artificial drainage devices to the addition of drugs like (5-FU) and mitomcycin, the danger of surgical failure as well as sight-threatening eye infection always looms.

Minimally-Invasive Surgery  With the advent of non-penetrating surgeries such as viscocanalostomy and canaloplasty, the Holy Grail of safer, effective glaucoma surgery may now be possible. Considered by many eye surgeons as the next frontier of glaucoma treatment, canaloplasty possesses the efficacy of filtering surgery without its attendant risks. Promising though non-penetrating techniques like canaloplasty may be, they are still relatively underutilized due to the lack of qualified surgeons who can perform them. Only a few glaucoma surgeons have completed the training necessary to offer this procedure to their patients with glaucoma.  Dr David Richardson is working to change this as he has devoted many hours to training other glaucoma surgeons in the technique of non-penetrating surgery.

With many breakthroughs in medicine over the past few decades, there is a wide range of effective glaucoma treatment options available . If you or someone you love has glaucoma, we hope this article gave you an overview of the modern treatment options. Ultimately, however, only your eye doctor or a glaucoma specialist can provide the proper evaluation required to initiate a treatment plan tailored to your needs, glaucoma severity, and preference.
