Glaucoma (Kala Motia): Symptoms, Causes, Types, Treatment and Prevention
Have you ever wondered whether you can lose your eyesight without experiencing any pain or noticeable symptoms?
Glaucoma, commonly known as Kala Motia, is one of the leading causes of irreversible blindness worldwide. It is an eye condition that damages the optic nerve, which carries visual information from your eyes to your brain.
The most concerning thing about glaucoma is that it often develops silently. Many people do not realise they have the condition until significant vision damage has already occurred.
At Gandhi Eye Centre, Faridabad, we emphasise the importance of regular eye examinations, early diagnosis and timely treatment to protect your eyesight.
What Is Glaucoma (Kala Motia)?
Glaucoma is a group of eye diseases that cause progressive damage to the optic nerve.
In many cases, increased intraocular pressure (IOP), also known as eye pressure, contributes to this damage. However, glaucoma can also develop in people whose eye pressure is within the normal range.
The optic nerve plays an important role in vision. Once its nerve fibres are permanently damaged, the lost vision generally cannot be restored.
This is why early detection and proper management are extremely important.
What Are the Causes of Glaucoma?
Glaucoma usually develops due to damage to the optic nerve. Increased pressure inside the eye is an important risk factor.
Common risk factors include:
Increased intraocular pressure.
Family history of glaucoma.
Increasing age.
Diabetes.
High myopia (severe minus power).
Previous eye injury.
Long-term use of steroid medications, including certain eye drops.
Certain structural conditions of the eye.
People with a family history of glaucoma should be especially careful about regular eye examinations.
What Are the Symptoms of Glaucoma?
Symptoms depend on the type and stage of glaucoma.
In early-stage glaucoma:
Usually no noticeable symptoms.
Gradual loss of peripheral (side) vision.
Difficulty noticing objects from the sides.
In advanced glaucoma:
Tunnel vision.
Difficulty walking or navigating surroundings.
Reduced visual field.
Severe vision impairment.
Symptoms of Acute Angle-Closure Glaucoma:
This is a medical emergency and may cause:
Sudden severe eye pain.
Redness in the eye.
Blurred vision.
Halos around lights.
Severe headache.
Nausea and vomiting.
If you experience these symptoms, seek immediate emergency eye care.
What Are the Different Types of Glaucoma?
There are several types of glaucoma. The most common include:
1. Primary Open-Angle Glaucoma
This is the most common type of glaucoma. It develops gradually when the eye's drainage system does not function properly, causing pressure to build up in the eye.
It usually has no early warning symptoms and may cause gradual loss of peripheral vision.
2. Angle-Closure Glaucoma
This occurs when the drainage angle of the eye becomes blocked or narrowed, preventing fluid from draining properly.
It can develop suddenly and cause severe eye pain, redness, blurred vision and headache. Acute angle-closure glaucoma requires immediate treatment.
3. Normal-Tension Glaucoma
In this type, optic nerve damage occurs even though eye pressure remains within the statistically normal range.
Regular optic nerve examination and visual field testing are important for diagnosis.
4. Secondary Glaucoma
This type develops due to another eye condition, injury, inflammation, certain medications or other underlying medical problems.
5. Congenital Glaucoma
This is a rare type of glaucoma present at birth or developing during early childhood. Symptoms may include excessive watering, sensitivity to light and an enlarged or cloudy-looking eye.
How Is Glaucoma Diagnosed?
Glaucoma cannot be diagnosed through eye pressure measurement alone. A comprehensive eye examination is required.
Your eye specialist may recommend the following tests:
1. Intraocular Pressure (IOP) Measurement
A test called tonometry measures the pressure inside your eyes.
2. OCT (Optical Coherence Tomography)
OCT provides detailed images of the optic nerve and retinal nerve fibre layer. It helps identify structural damage associated with glaucoma.
3. Humphrey Visual Field Test
This test checks your central and peripheral vision to detect areas of vision loss caused by glaucoma.
4. Fundus Examination
The doctor examines the optic nerve to identify changes in its appearance, including optic disc cupping.
5. Gonioscopy
This examination helps the doctor evaluate the drainage angle of the eye and determine the type of glaucoma.
What Are the Treatment Options for Glaucoma?
Glaucoma treatment aims to reduce eye pressure and prevent further damage to the optic nerve.
The treatment depends on the type and severity of glaucoma.
1. Glaucoma Eye Drops
Prescription eye drops are commonly used to lower eye pressure. They may reduce fluid production inside the eye or improve fluid drainage.
Patients should use these medications regularly as prescribed by their ophthalmologist.
2. Laser Treatment
Laser procedures may help improve fluid drainage or reduce eye pressure.
Common procedures include:
Selective Laser Trabeculoplasty (SLT).
Laser Peripheral Iridotomy (LPI).
The appropriate procedure depends on the type of glaucoma.
3. Glaucoma Surgery
In advanced cases or when medications and laser treatments are insufficient, surgery may be recommended.
Common surgical procedures include trabeculectomy and glaucoma drainage device implantation.
The main goal is to control eye pressure and protect the remaining vision.
Can Glaucoma Be Cured?
Currently, there is no permanent cure for glaucoma. However, with early diagnosis and appropriate treatment, its progression can often be slowed or controlled.
Vision already lost due to glaucoma generally cannot be recovered.
Therefore, regular follow-up examinations and consistent use of prescribed medications are essential.
Who Is at Higher Risk of Developing Glaucoma?
You should be particularly careful if:
You are above 40 years of age.
Someone in your family has glaucoma.
You have diabetes.
You have high minus spectacle power.
You have experienced an eye injury.
You have used steroid medications for a prolonged period.
You have previously been diagnosed with elevated eye pressure.
Even without symptoms, people with these risk factors should consult an eye specialist about appropriate glaucoma screening.
How Can You Protect Your Eyes from Glaucoma?
Although glaucoma cannot always be prevented, certain steps can help detect it early and reduce the risk of serious vision loss.
Get regular comprehensive eye examinations.
Monitor eye pressure as advised by your doctor.
Inform your eye specialist about any family history of glaucoma.
Use prescribed eye drops regularly.
Never stop glaucoma medication without medical advice.
Avoid using steroid eye drops without a prescription.
Attend all scheduled follow-up appointments.
Remember, normal vision does not necessarily mean that you are free from glaucoma.

Frequently Asked Questions (FAQs)
1. What is the difference between Cataract and Glaucoma?
Cataract causes clouding of the natural lens of the eye, resulting in blurred vision. Glaucoma damages the optic nerve and can cause permanent vision loss. Cataract-related vision loss can often be improved with surgery, whereas glaucoma-related nerve damage is generally irreversible.
2. Can glaucoma cause blindness?
Yes. Untreated glaucoma can cause permanent blindness. Early diagnosis and proper treatment can help protect the remaining vision.
3. Is glaucoma painful?
Most common types of glaucoma do not cause pain in their early stages. However, acute angle-closure glaucoma can cause sudden and severe eye pain.
4. Can glaucoma occur without high eye pressure?
Yes. Normal-tension glaucoma can damage the optic nerve even when eye pressure is within the statistically normal range.
5. Is glaucoma hereditary?
Yes. Family history is an important risk factor. People with close relatives who have glaucoma should undergo regular eye examinations.
6. Can glaucoma be treated with eye drops?
Many patients can manage glaucoma with prescription eye drops. Some may require laser treatment or surgery depending on the severity of the condition.
7. At what age should I get tested for glaucoma?
Glaucoma screening is particularly important after the age of 40, especially for people with additional risk factors. Your ophthalmologist can recommend the appropriate examination schedule.
