What is Glaucoma?
Glaucoma is a medical condition where the pressure inside the eyes becomes too high, causing damage to the delicate nerves that help us see. This damage can lead to gradual vision loss, starting from the outer edges of our vision and eventually affecting our ability to see clearly.
Symptoms
Glaucoma develops slowly and without any noticeable symptoms in its early stages. As the condition progresses, an individual experiences the following:
- Patchy blind spots in the peripheral (side) or central vision
- Tunnel vision, which is narrow vision
- Severe eye pain
- Headaches
- Blurred vision
- Halos, or bright circles of light
Causes
The main cause of glaucoma is an increase in pressure inside the eye. This pressure damages the optic nerve, leading to vision loss. Factors such as poor drainage of fluid in the eye or an imbalance in the production and drainage of this fluid can contribute to the development of glaucoma.
Types
There are different types of glaucoma, including:
Congenital Glaucoma
A rare eye condition present at birth that can lead to increased eye pressure, affecting vision and potentially causing blindness.
Lens Induced Glaucoma
Glaucoma caused by changes in the eye’s lens, leading to increased pressure and potential damage to the optic nerve.
Malignant Glaucoma
A severe form of glaucoma where fluid builds up in the eye, causing a sudden increase in pressure and potential vision loss.
Secondary Glaucoma
Glaucoma that develops as a result of another eye condition, injury, or medication, leading to increased eye pressure and potential vision problems.
Open Angle Glaucoma
A common type of glaucoma where the eye’s drainage system becomes less efficient over time, causing a gradual increase in eye pressure and potential vision loss.
Closed Angle Glaucoma
A type of glaucoma where the drainage angle of the eye becomes blocked, leading to a sudden increase in eye pressure, which can be a medical emergency requiring immediate treatment to prevent vision loss.
Glaucoma treatment for each type is adjusted according to the individual needs of the patient.
Risk Factors
Several factors can increase the risk of developing glaucoma, including:
- Age (over 60)
- Family history of glaucoma
- High intraocular pressure
- Thin corneas
- Conditions like diabetes and heart disease
- Long-term use of corticosteroid medications
How to prevent
These are the steps you can take to reduce the risk and manage the condition effectively or you can contact us the best eye hospital of Maharashtra
Regular eye exams to detect glaucoma early.
Maintain a healthy lifestyle with regular exercise and a balanced diet.
Protect your eyes from injury and UV radiation by wearing sunglasses.
Manage other health conditions that may contribute to glaucoma risk.
Types of Treatments
Treatment aims to lower intraocular pressure and prevent further damage to the optic nerve. Depending on the type and severity of condition, glaucoma treatment options may include the following:
Eye Drops
Oral medications, if eye
drops are insufficient
Laser therapy to improve
fluid drainage in the eye
Surgical procedures to create
new drainage pathways
Regular follow-up appointments are crucial for monitoring progress and adjusting the glaucoma treatment as needed.

Frequently Asked Questions
Common queries about the treatment are addressed in this section. Find your answers here.
What is glaucoma?
Glaucoma is a group of eye conditions that damage the optic nerve, leading to progressive vision loss. It is often associated with increased pressure inside the eye, known as intraocular pressure (IOP).
What are the different types of glaucoma?
The main types of glaucoma include primary open-angle glaucoma (POAG), angle-closure glaucoma, normal-tension glaucoma, and secondary glaucoma, which can occur due to other eye conditions or medical factors.
What are the symptoms of glaucoma?
In the early stages, glaucoma may not cause noticeable symptoms. As the condition progresses, symptoms may include gradual loss of peripheral vision, tunnel vision, eye pain, blurred vision, halos around lights, and headaches.
How is glaucoma diagnosed?
Glaucoma is diagnosed through a comprehensive eye examination, which may include measurements of intraocular pressure, examination of the optic nerve, visual field testing, and assessment of corneal thickness. Early detection is crucial for preventing vision loss.
What causes glaucoma?
Glaucoma is typically caused by an imbalance in the production and drainage of aqueous humor, the fluid that circulates inside the eye. This imbalance can lead to increased intraocular pressure, which damages the optic nerve over time.
Can glaucoma be cured?
Currently, there is no cure for glaucoma. However, treatment can help manage the condition and slow the progression of vision loss. Early detection and adherence to treatment are key to preserving vision and preventing further damage.
What are the treatment options for glaucoma?
Treatment for glaucoma may include prescription eye drops to lower intraocular pressure, oral medications, laser therapy (such as selective laser trabeculoplasty or laser peripheral iridotomy), and surgical procedures (such as trabeculectomy or drainage implants) to improve fluid drainage from the eye.
Can glaucoma lead to blindness?
If left untreated or poorly managed, glaucoma can lead to irreversible vision loss and blindness. However, with early diagnosis and appropriate treatment, the progression of glaucoma can often be slowed or halted, preserving vision and quality of life.
Who is at risk for glaucoma?
While anyone can develop glaucoma, certain factors increase the risk, including age (especially those over 60), family history of glaucoma, African or Hispanic ancestry, high intraocular pressure, certain medical conditions (such as diabetes or hypertension), and previous eye injuries or surgeries.
How often should I have my eyes checked for glaucoma?
The frequency of eye exams for glaucoma depends on your age, risk factors, and overall eye health. As a general guideline, adults over the age of 40 should have a comprehensive eye exam every 2-4 years, while those at higher risk may need more frequent screenings. Your eye care professional can recommend a personalized schedule based on your individual needs.
