Glaucoma therapeutics are the latest developments in the field of drug discovery and development. Glaucoma is a disease which leads to vision loss and is progressive, causing vision loss. Generally, glaucoma therapeutics begin with medicinal eye drops, belonging to the class of beta-blockers, alpha-agonists, prostaglandin inhibitors, selective serotonin reuptake inhibitors, and tricyclic antidepressants. These drugs have various side effects like nausea, vomiting, diarrhea, constipation, electrolyte imbalance, fatigue, muscle weakness, dry mouth, itching and burning sensations, frequent urination, and infections. Thus, these drugs do not provide complete relief.
New research shows that glaucoma can be eliminated by using laser surgery or infrared coagulation therapy (ICP), a form of radiation therapy. ICP involves the application of an infrared beam to the eye, which causes damage to the optic nerve and ultimately leads to obstructive endolymphoma, leading to vision loss. This procedure is performed under local anesthesia. During laser coagulation therapy, a laser ray is directed at the coagulated areas, causing damage to vessels of internal body tissues, leading to elimination of glaucoma. While it has many positive effects, it is quite expensive.
Glaucoma therapeutics can also be given as Intraocular Protein Injection (IPPI). It is given by means of tiny syringe-dispensers into the eye through a net or a pin. It contains an anti-coagulant that effectively destroys eye tissue and prevents scarring. IPPI is ideal for patients suffering from mild glaucoma.
For patients diagnosed with lower intraocular pressure (IOP), a laser eye treatment called Trabeculectomy is performed. The laser beam cuts portions of the trabecular meshwork. It causes the opening to shrink, allowing fluid to drain into the eye. The treated eye will then be protected by a protective capsule to reduce pressure. The surgery is performed under local anesthesia and lasts about an hour.
Generally, glaucoma is caused by high intraocular pressure. Surgery can help reduce intraocular pressure and eliminate glaucoma. Some physicians prefer to treat glaucoma early in the course of the disease, before it causes vision loss. This strategy prevents the need for continuous treatment and possible surgical complications.
Since laser eye surgery can eliminate many causes of glaucoma, patients are often able to return to normal activities and live perfectly normal lives again. This is true even if a large portion of the eye's tissue has been destroyed. However, this is not always the case. Sometimes, damaged optic nerves may never regain their previous function. For these patients, laser eye surgery offers the best chance for recovery.
In general, there is no known side effect of laser eye surgery. The only complication that has been identified is temporary blindness due to increased light sensitivity after the procedure. Fortunately, this is usually temporary and does not cause permanent damage to vision. With proper care after glaucoma therapeutics and the newest laser eye surgery techniques, many people can go on to enjoy a completely normal life.
Glaucoma can range from mild to serious conditions. Some forms are hereditary, while others are caused by unhealthy lifestyle factors. Regardless of their cause, glaucoma puts thousands to lose each year, and significantly affects quality of life. For this reason, more people than ever before are using non-surgical laser technology in glaucoma therapeutics. The results are impressive.
