Glaucoma Surgery
Relevant information about Glaucoma Surgery.The Glaucoma Surgery is one of the most common procedures to the human eye. Glaucoma disease affects eye nerve, and if it´s not treated in time, could cause permanent blindness. The surgery involves either laser treatment or making a cut in the eye to reduce the intraocular pressure. Generally, the patient has a full recovery a very short period of time.
Patient with Glaucoma disease might feel some of the following symptoms: seeing of colored halos around the source of light, headache and pain in the eye, gradual loss of side vision and restriction of visual camp. If the illness is not treated, the pressure over the optical nerve could cause it permanent damage, beside lot of pain to the patient. The blindness is the worst consequence of the Glaucoma illness. There are two main types of glaucoma: Open-angle glaucoma (painless) and Closed-angle glaucoma (painful). This one is considerate an ophthalmologic emergency. All Glaucoma Surgery procedures (laser or non-laser) are designed to accomplish one of two basic results: decrease the production of intraocular fluid or increase the outflow of this same fluid. Currently the goal of Glaucoma Surgery is to reduce or stabilize intraocular pressure. When this goal is accomplished, damage to ocular structures — especially the optic nerve — may be prevented. If the surgery is made on time, there are big chances of save the patient´s affected eye. The surgery revert the anomalies caused by the overpressure. It´s also important to tell that the causes of this illness are stress vision´s high demand and genetic predisposition.
The laser surgeries objetive is to lower intraocular pressure by enhancing the drainage of aqueous fluid or slowing its production. The kind of laser surgery used depends on the type of glaucoma being treated. The length of time the pressure remains lowered depends on the type of laser surgery, the kind of glaucoma, and the patient´s physiological conditions. In some cases, laser surgery may have to be repeated to control internal eye pressure more effectively. Patient will need medications to maintain fluid pressure within the eye. If the laser therapy does not lower the pressure in the eye or the effects wear off, the ophthalmologist may recommend conventional surgery. Conventional surgery is used when laser surgery procedure has failed or is less desirable, because the glaucoma type treated or the patient eye´s conditions. A small incision is made in the sclera of the eye and a flap of tissue is left to cover the incision, allowing slow release of fluid from the inside the eye to its outer layers. The procedure results in the formation of a small blister-like bump called a “bleb.” The bleb is covered by the eyelid and is usually not visible. The excess fluid is carried away as it is absorbed into the bloodstream. Depending of the glaucoma type and its grade of advance, a deeper incision can be performed by the ophthalmologist to improve the release of fluid.
Always, a laser surgery demands less time of rehabilitation and dressing to the patient. But despite the fact that many people can return to normal activities shortly after Glaucoma Surgery, most ophthalmologists advise patients to avoid heaving lifting, straining, and bending for a couple weeks. The conventional glaucoma surgery recovery time is longer than that of the laser procedure. Patient ´s recovery demands from two to four weeks. It might take up to two months for glaucoma surgery results to become apparent and vision to stabilize, depending eye previous-procedure conditions and evolution. Periodic checkups are required to monitor the patient’s progress and even a new/s surgery/ies, if the specialist decides so.
Usually, complications appear in the incision Glaucoma Surgery type. glaucoma surgery complications include bleeding, infection, discomfort, and pain. Laser surgery type is lesser dangerous in this point. Rare laser glaucoma surgery complications include a short term increase in intraocular pressure or an excessive drop in pressure. These complications can be managed with medications. There is also a small risk of cataract formation after surgery. Of course, a bad ophthalmologist’s praxis could damage eye biological compositions, optical nerve, etc, causing permanent disabilities.
