The most prevalent cause of irreversible blindness is glaucoma. It’s a complicated disorder in which an optic nerve lesion causes progressive eyesight loss. Our vision deteriorates when the optic nerve, which transmits visual data from the eye to the brain, is harmed.
Although glaucoma causes lifelong vision loss and, in severe cases, blindness, early identification of the condition and timely treatment can assist in reducing the disease’s impact.
MIGS is a group of glaucoma treatments that use microscopic incisions to lower IOP and improve natural outflow channels rather than bypassing the drainage system, as is the case with normal glaucoma surgery. Traditional glaucoma surgery offers a greater return in that it is more likely to achieve the lowest IOP possible, but it also comes with a higher risk. The most feared hazard of traditional surgery is lowering the IOP TOO low, exposing the patient to vision-threatening issues. Although MIGS treatments may not always result in substantial IOP reductions, the possibility of achieving an IOP that is too low is almost minimized.
Compared with aberrant blood flow in coronary artery disease, irregular ocular fluid outflow. Angioplasty is a minimally invasive procedure that treats a blocked coronary artery with fewer risks than a coronary artery bypass. If the angioplasty procedure is successful, the patient will be overjoyed. If it doesn’t, a bypass is necessary, and the treatment’s increased risks are warranted. Similarly, if a MIGS procedure fails, traditional surgery remains an alternative.
Aqueous humour, the fluid in the front chambers of the eye, normally drains at the same rate as it is produced, maintaining equilibrium. When the drainage pathways become blocked, glaucoma develops. As a result, the mounting pressure pushes the lens back gradually. As a result, the vitreous humour, a fluid found in the eye’s larger posterior chamber, pushes against the blood vessels and optic nerve, damaging them.
Although glaucoma can result in irreparable vision loss and even blindness in extreme cases, early detection and timely treatment can assist in mitigating the disease’s effects.
A MIGS can be one of the following types:
Sharp Sight (Group of Best Eye Hospitals in Delhi) features state-of-the-art technology for glaucoma diagnosis. Our glaucoma specialists have significant experience doing minimally invasive glaucoma procedures. There are numerous therapy options and tactics available after the condition has been detected. Eye drops are commonly recommended to patients in order to alleviate pressure. If it doesn’t work, surgery or the use of lasers to reduce eye strain are options. If you’ve been diagnosed with glaucoma or have a family history of the disease, talk to your eye doctor about the best treatment options for you.
- Ab-Interno Canaloplasty (ABiC):
The catheter is spun 360 degrees to penetrate the whole drainage canal. The catheter is then withdrawn, and viscoelastic (an expanding and transparent substance) is introduced into the drainage system. Breaking down adhesions and blockages within the drainage system improves fluid drainage and IOP. This can be done as part of cataract surgery or as a stand-alone procedure.
- iStent :
The iStent is currently the smallest implant ever put into a person. Under extreme magnification, the device is implanted exactly at the drainage angle to bypass ocular fluid around the ill trabecular meshwork outflow tissue and straight into the less afflicted tissue downstream. Unlike standard glaucoma surgery, the surgeon does not bypass the whole outflow system, avoiding the greater dangers that come with it.
- Gonio-Assisted Transluminal Trabeculotomy (GATT) :
GATT has recently been proven to be beneficial for open angle glaucoma in people of all ages. A catheter similar to ABiC is used to intubate the whole drainage canal. GATT, on the other hand, removes the catheter in such a way that it cuts through the underdeveloped drainage tissue, allowing for more direct ocular fluid outflow downstream.
Trabectome is a revolutionary operation that successfully lowers intraocular pressure in diseased eyes in 80% of cases. During the minimally invasive treatment, the surgeon merely makes one small incision. With the Trabectome, a specially designed device, the surgeon eliminates tissue debris that is impeding the passage of fluid in the eye. The procedure is performed as an outpatient using a local anesthetic. If any stitches are used, the incision is closed with one stitch, and the procedure takes less than 10 minutes on average!
- Safety: The FDA has authorized it, and Dr. Stiles has undergone extensive clinical training before making the operation available. He is currently teaching this treatment to other surgeons around the country.
- Flexible: it is possible to combine the operation with cataract extraction.
- Glaucoma management medications are frequently no longer required by patients. Our objective is to maximize health-care resources at all times.
- Patients report no significant discomfort during or after the procedure.
- Minimally invasive surgery: Fewer incisions mean less pain and a quicker recovery.
- Eighty percent of individuals saw an improvement in their eyes’ health and function.
- Precision is improved with specially developed surgical instruments.
