Glaucoma Evaluation & Treatment at Anand Eye Centre
Glaucoma is a group of eye conditions that can damage the optic nerve, often due to raised eye pressure or pressure sensitivity of the nerve. It may progress silently in the early stages, so timely diagnosis, monitoring and treatment are important for preserving vision.
What is glaucoma?
Glaucoma refers to a group of disorders that can harm the optic nerve, which carries visual signals from the eye to the brain. If not detected and managed in time, glaucoma may lead to permanent blind spots and progressive vision loss.
In many patients, glaucoma does not cause obvious symptoms initially. This makes regular eye examination important, especially for people above 40 years, those with family history, high eye pressure, diabetes, high myopia or previous eye injury.
Optic nerve damage
Glaucoma affects the optic nerve. The aim of treatment is to protect remaining vision and slow progression.
Eye pressure matters
Raised intraocular pressure is a major risk factor, although glaucoma can sometimes occur even with normal pressure.
Monitoring is essential
Glaucoma usually needs long-term follow-up through eye pressure checks, optic nerve assessment and visual field testing.
Who should be checked for glaucoma?
Glaucoma can affect people with or without symptoms. A person may need glaucoma evaluation if they have raised eye pressure, optic nerve changes, family history of glaucoma, reduced side vision or suspicious findings during a routine eye check-up.
At Anand Eye Centre, glaucoma evaluation is based on clinical examination and diagnostic tests to assess eye pressure, optic nerve health and visual field status.
Routine eye check-ups become more important with age.
Risk can be higher if close relatives have glaucoma.
Raised pressure may need detailed glaucoma work-up and monitoring.
Peripheral vision loss, halos, headache or blurred vision should be evaluated.
What are the symptoms of glaucoma?
Many cases of glaucoma do not cause noticeable symptoms in the early stage. Some symptoms may appear gradually, while sudden symptoms may occur in acute angle-closure glaucoma and need urgent attention.
Loss of side vision
Gradual loss of peripheral vision may occur and may not be noticed until significant damage has developed.
Blurred vision
Blurred vision may occur in some patients, especially when eye pressure fluctuates or another eye condition is present.
Halos around lights
Seeing colored rings or halos around lights may be associated with raised eye pressure in some cases.
Eye pain or headache
Eye pain, headache and redness can occur in certain types of glaucoma and should not be ignored.
Nausea with eye pain
Nausea, vomiting and severe eye pain may indicate an urgent eye pressure-related episode.
Sudden vision loss
Sudden reduction in vision needs prompt eye evaluation to identify the cause and urgency.
What causes glaucoma?
Glaucoma is linked with damage to the optic nerve. In many patients, this is associated with increased eye pressure due to reduced drainage of fluid inside the eye. However, glaucoma can also occur in some people with normal eye pressure.
The risk and treatment plan depend on the type of glaucoma, eye pressure level, optic nerve appearance, visual field findings, corneal thickness, age, family history and associated eye or systemic conditions.
A major risk factor that requires careful evaluation and follow-up.
People with close family members having glaucoma may need earlier screening.
Age, narrow angles, high myopia or previous eye injury may increase risk.
Diabetes, long-term steroid use and certain eye conditions may affect risk.
Glaucoma screening may include:
- Eye pressure measurement
- Slit lamp examination
- Optic nerve evaluation
- Gonioscopy for angle assessment
- Visual field test
- OCT optic nerve / retinal nerve fibre layer scan
- Corneal thickness measurement where required
- Follow-up comparison over time
How glaucoma is evaluated at Anand Eye Centre
Glaucoma diagnosis is not based on one reading alone. A complete assessment usually combines eye pressure measurement, optic nerve examination, imaging and visual field testing where required.
Medical history and risk review
The doctor reviews age, family history, previous eye pressure, medicines, diabetes, steroid use, eye injury and visual symptoms.
Eye pressure measurement
Intraocular pressure is checked because raised pressure is an important glaucoma risk factor.
Optic nerve examination
The optic nerve is examined for signs such as cupping or structural change that may suggest glaucoma.
OCT and visual field test where needed
OCT and visual field testing may help measure nerve fibre loss and functional field changes.

The doctor may advise eye drops, laser, surgery or observation depending on diagnosis, risk and stage.
Glaucoma treatments that may be considered
Glaucoma treatment is personalised. The main objective is to reduce eye pressure to a safer level and prevent or slow further optic nerve damage.
Glaucoma eye drops
Eye drops may be prescribed to reduce eye pressure. Regular use and follow-up are important for control.
Laser treatment
Laser may be advised in selected cases depending on the type of glaucoma and drainage angle findings.
Trabeculectomy
A surgical option that may be considered when pressure control is inadequate with medicines or other measures.
Glaucoma implants
Implants or drainage devices may be considered in selected complex or advanced cases.
MIGS in selected cases
Minimally invasive glaucoma surgery may be suitable for selected patients depending on eye condition and treatment goals.
Long-term follow-up
Glaucoma needs periodic review to check pressure, optic nerve status, visual field and treatment response.
Living with glaucoma: what patients should remember
Glaucoma management depends heavily on regular follow-up and correct use of medicines. Missing medicines or stopping drops without medical advice can increase the risk of progression.
Use drops as advised
Take prescribed drops regularly and inform the doctor if there is irritation, allergy or difficulty using them.
Do not skip follow-up
Glaucoma may progress silently, so follow-up visits are needed even when vision feels stable.
Bring previous records
Old prescriptions, visual field reports, OCT scans and pressure readings help compare disease progression.
Glaucoma care connects with complete eye care
Glaucoma assessment may overlap with diagnostics, cataract evaluation, retina care, neuro-ophthalmology and general eye check-up. These related pages may help patients understand the complete care pathway.
Have high eye pressure, family history of glaucoma or unexplained vision changes?
Early glaucoma evaluation can help detect risk, document baseline findings and start appropriate monitoring or treatment. For severe eye pain, sudden blurred vision, halos, nausea or sudden vision loss, seek urgent eye care.

Frequently asked questions on glaucoma
These answers are general and do not replace personal medical advice. The final diagnosis and treatment plan depends on clinical examination.
Can glaucoma be cured?
Glaucoma usually cannot be cured in the sense of reversing existing optic nerve damage. However, treatment can often help control eye pressure and slow further progression when diagnosed and monitored properly.
Can glaucoma cause blindness?
Untreated or advanced glaucoma can cause severe vision loss. Timely diagnosis, regular follow-up and appropriate treatment can reduce the risk of progression.
What is the best treatment for glaucoma?
There is no single best treatment for every patient. Treatment may include eye drops, laser, trabeculectomy, glaucoma implants, MIGS or observation depending on glaucoma type, stage and eye pressure control.
At what age should glaucoma screening start?
Many people should begin regular glaucoma screening after 40 years of age. Earlier evaluation may be needed if there is family history, high eye pressure, high myopia, diabetes, steroid use or previous eye injury.
Does glaucoma always cause pain?
No. Many glaucoma cases are painless and silent in the early stages. Pain, redness, halos and nausea may occur in acute pressure rise and need urgent evaluation.
Can I stop glaucoma drops if my pressure becomes normal?
No. Glaucoma drops should not be stopped without medical advice. Eye pressure may rise again after stopping treatment, increasing the risk of further optic nerve damage.
Why are visual field tests repeated?
Visual field tests help monitor functional vision loss. Repeating them over time helps the doctor assess whether glaucoma is stable or progressing.
Can cataract and glaucoma happen together?
Yes. Cataract and glaucoma can coexist, especially in older adults. The doctor will assess both conditions and advise the sequence of management based on clinical findings.
