Glaucoma

Of all the conditions prevailing human eye, Glaucoma is the most threatening one. It is also known by the name of ‘Kala Motia’ or as ‘a silent thief of vision’ due to its painless nature. Clinically, it is a slowly manifesting disease distinguished by acute damage of optic nerves caused due to retinal ganglion cell loss.

Common symptoms to look out for here are -

  • Slow degradation of the side vision
  • Headaches accompanied by the redness & pain in eyes
  • Rapidly changing glass prescription
  • Reduced vision in low light conditions or at night
  • Seeing colourful halo rings around bulbs
  • Pain around eyes after coming into the light from darkness

Anyone can have this disease, however, few people are more susceptible to it. They are the ones -

  • Aged above 40 years
  • With hypertension, migraine or diabetes
  • Having myopia (nearsightedness) of open-angle type or hyperopia (farsightedness) of close angle type
  • Having glaucoma family history

Types of Glaucoma

This malady is of 7 different types.

Primary Open Angle Glaucoma (POAG)

Primary Open Angle Glaucoma is a chronic disorder that needs lifelong monitoring as well as medicines for maximum control. There are no associated early stage symptoms to identify or diagnose POAG in patients. Few of them notice patchy area vision loss, delayed adjustment of eyes to dim lighting condition or something as vague as a minor headache. It is only through proper IOP evaluation by an eye specialist can diagnose it. Based on the findings, doctors recommend more tests to become sure about the diagnosis.

Angle Closure Glaucoma

It occurs in cases where the eye filtration angle is closed or narrow, resulting in blockage of aqueous outflow plus elevated IOP. This may be either primary or secondary to systemic or ocular causes.

Amongst the Indian population, Primary Angle Closure Glaucoma (PACG) is pretty common. Symptoms include nausea/vomiting, episodic eye ache, seeing coloured halos, redness in the eye, blurred vision, and a general feeling of heaviness in the body. Elevated IOP and shallowness in the anterior chamber can be diagnosed upon examination.

Secondary Glaucoma

Glaucoma concerning other systemic or ocular cases is known as Secondary Glaucoma. Based on the position of obstruction with respect to trabecular meshwork, it is further divided into three sub categories:

  • Pre-trabecular
  • Trabecular
  • Post-trabecular

Pigmentary Glaucoma

This glaucoma is generally diagnosed in the eyes of young male patients accelerated many-a-times due to exercise. In this case, the iris rubs against zonules and releases pigment that subsequently blocks trabecular meshwork.

Pseudoexfoliative Glaucoma

Pseudoexfoliative Glaucoma can be related to zonal weakness and cataract. That is why it needs extra precaution at the time of surgery. Scientifically speaking, it is caused by amyloid-like white fibrillary substance deposition at trabecular meshwork that in turn clogs angles and elevates IOP.

Steroid-Induced Glaucoma

Typically seen in steroid sensitive (responders) people using systemic or topical steroids, it arises within weeks of usage. Risk factors further elevating the situation here are glaucoma family history, diabetes and myopia. Treatment encompasses shifting to medication of non-steroidal nature. Monitoring and caution are needed in future too.

Traumatic Glaucoma

Any eye trauma that damages angle structure by scarring it, can cause this glaucoma. In these cases, treatment is very difficult. First medication is tried and if it fails, surgery remains the only option.

Glaucoma Treatment at Centre for Sight

The damage done by Glaucoma cannot be reversed, however, timely intervention can prevent further progress of this malady. The Glaucoma treatment at Centre for Sight aims to preserve the remaining vision of the suffering patient by lowering IOP so that no more damage can take place. Three approaches taken by the specialists at Centre for Sight to achieve it are - Medication, Laser & Surgery.

Medication

If manageable by medicines, the specialists prescribe eye drops, syrups and injections to the patients to manage the condition.

Laser

Different laser procedures are performed to contain different situations of Glaucoma. Depending on the type of Glaucoma, the specialists choose the best-suited one for the patient. Four laser procedures are as follows:

  • Peripheral Iridotomy (PI)
  • This laser procedure is suggested to the patients diagnosed with closed or narrow angles to treat or prevent pupillary block glaucoma. The release of pigment accompanied by a gush of aqueous indicates completion of the procedure. After the operation, the patient may be recommended topical steroids. Probable complications, in this case, are elevated IOP, iritis, lens damage, corneal endothelial damage and iris bleeding.

  • Laser Trabeculoplasty
  • As the supplementary procedures to lower a patient’s IOP who is suffering from open-angle glaucoma, Argon Laser Trabeculoplasty (ALT) and Selective Laser Trabeculoplasty (SLT) have gained popularity in recent years.

  • Transscleral Diode Cyclophotocoagulation
  • This laser surgery reduces aqueous production by the usage of a contact diode probe. The patients with poor vision potential and who have been unresponsive to medication plus deemed unfit for surgery are treated with this procedure.

  • Laser Suture Lysis
  • During the postoperative stage, the selective suture-lysis is done using diode or argon laser to improve aqueous outflow and control any possible IOP spike.

Surgery

Surgeries here are treated as last resort after a patient fails to respond to medication or lasers. Trabeculectomy surgery aims at providing the aqueous flow an alternative drainage channel to lower IOP. And if it fails too, doctors suggest taking the route of glaucoma drainage device. A bio-compatible drainage implant is placed in eye, which allows the draining of aqueous.

FAQs

What are early signs of Glaucoma?

Glaucoma is a silent disease. Most people will not have any significant symptoms. Occasionally someone may feel vague eye ache especially in the evening and in dim light conditions. Other symptoms include redness, watering, coloured halos around light and blurring of vision.

Can Glaucoma be cured completely?

Glaucoma can be controlled but not cured. Just like many other chronic diseases, we can prevent glaucoma from progressing further with medicines, lasers or surgery but it needs regular monitoring.

What should glaucoma patients avoid?

Glaucoma patients should avoid taking steroids in any form and if needed, must inform their doctor that they have glaucoma. Self-medication should be avoided at any cost. In addition, avoid excessive tea or coffee intake. Avoid consuming large quantities of water/fluids in one go.

Is coffee bad for glaucoma?

Excessive coffee (more than 2-3 cups a day) is associated with elevated eye pressure and is best avoided.

How to get rid of eye pressure?

You need to get yourself examined by an eye specialist, who will perform a couple of tests to measure the eye pressure and check if it is elevated. Depending on the measurements, he/she might recommend few eye tests followed by appropriate treatment.

Can you reverse glaucoma?

Glaucoma cannot be reversed but further damage can be stopped. Only in some cases like children, an early intervention may sometimes reverse the damage and restore an improved visual field or optic nerve function.

Beware of Glaucoma – A Silent Thief of Vision

Glaucoma or ‘Kala Motia’ is a condition wherein an increased intraocular pressure damages the optic nerve thereby affecting vision. Glaucoma is a disease of the eye that slowly and painlessly takes away your sight. That’s the reason it is called ‘Silent Thief of Sight’.

There is no proven way to cure glaucoma or reverse loss of vision which has already been affected. Regular eye examination is the key to help detect this disease in early stages and preserve healthy vision.

At Centre for Sight, with our team of super specialists and advanced state-of-the-art equipment we are fully geared not only to detect early stages of Glaucoma but also its treatment and surgical management.

Since most people with glaucoma have no early symptoms or pain, it is important to see your eye doctor regularly so that it can be diagnosed early and glaucoma treatment can be done and an irreversible sight loss can be prevented. If you are over 40 years of age and have a family history of glaucoma, you should have a complete eye exam with an eye doctor at a glaucoma treatment hospital after every one to two years. For people in need of the latest glaucoma treatment, we have our centres spread across the country in cities like Delhi, Gurgaon, Hyderabad, Indore, and Jaipur etc. where you can avail the latest glaucoma services.

A fluid known as aqueous nourishes the front part of the eye. In the normal eye, the rate of production of aqueous matches the rate of its drainage, thereby maintaining optimal pressure inside the eye. With age, disease, trauma or other factors, the channels carrying this fluid may get blocked, increasing the pressure inside the eye. This increased pressure damages the optic nerve, which is the conduit of visual messages to the brain. Working silently, glaucoma damages the outer or peripheral vision first while maintaining the central vision and if not treated on time it may lead to loss of central vision and blindness.

Glaucoma is also called the silent thief of sight because in the early stages of the disease, there may be no symptoms. By the time glaucoma is detected, the patient has already suffered extensive peripheral vision damage which can no longer be restored. The statistics reveal that by the time people realize that something is amiss and consult a doctor for glaucoma treatment, 90% of them have lost half of their vision. It comes so slowly that it goes unnoticed in most of the people. Worldwide, it is the leading cause of irreversible blindness.

Early detection is the key to preserve vision. Once detected, glaucoma can be controlled by medicines (eye drops) or surgery to prevent further vision loss. This can only be done through disciplined and regular glaucoma treatment from an eye specialist. Treatment of Glaucoma is life-long. Glaucoma treatment may include medical management, surgical management or management by lasers.

Recent Advances in Glaucoma Management

In recent times, there have been a number of advancements in glaucoma management. In the investigational aspect, we now have more sophisticated machines which are able to detect Glaucoma at a very early stage, when no damage to the fibers of the eyes has occurred and this helps in starting the glaucoma treatment on time thereby actually preventing the onset of any possible damage to the eye.

The availability of superior anti glaucoma eye drops has also helped a lot. Newer formulations in medications have also been introduced lately thereby creating wider choice of treatment options for the ophthalmologist.

Management of glaucoma by lasers has also seen ushering in of newer technology where acute angle closure can be promptly dealt with, even when the conventional technique of making a hole by YAG laser does not yield desired results. Apart from the above breakthroughs, at Centre for Sight we also possess a number of new techniques in glaucoma surgery like planting the glaucoma filtration device (for controlled filtration), new kind of valves and use of sophisticated vitreoretinal techniques to help in conducting complicated glaucoma procedures which make Centre for Sight the preferred destination for best glaucoma treatment in Delhi.

The introduction of sophisticated techniques for glaucoma treatment provides tremendous hope for the future of comprehensive medical and surgical management of glaucoma. Centre for Sight has a panel of experienced glaucoma specialists specializing in and providing advanced glaucoma treatment in Delhi.

The goal of glaucoma treatment is to lower pressure in the eye thereby reducing the damage to the optic nerve. To treat your condition, doctor may choose to either lower the eye pressure through medicated eye drops, or improve drainage of fluid in the eye or lower the amount of the fluid produced in the eye. With a panel of experienced glaucoma specialists, Centre for Sight is a destination for treatment of glaucoma in Delhi and India.
