01
Blocked or limited drainage
Aqueous humour must leave the eye through the angle. When outflow is reduced, pressure rises and the nerve is compressed over time.

If you are over 40, regular eye checks help screen for glaucoma before vision is lost. At M G Eye Foundation, Bara Gamharia, Jamshedpur, DR KUMAR SAKET monitors eye pressure, the optic nerve and visual function, and plans drops, laser or surgery according to the type and stage of disease.
What is glaucoma?
Glaucoma is a group of diseases that slowly damage the optic nerve, which carries visual information from the eye to the brain. Raised intraocular pressure is the main treatable risk, but the nerve can also suffer when blood flow is reduced. Untreated glaucoma can lead to irreversible blindness. Early disease often has no pain, which is why screening matters.
Why it develops
Causes
More than one factor may act together. Age and family history raise risk even when the eye feels normal.
02
Medications
Corticosteroids and some dilating drops can raise pressure in susceptible people. Always tell the doctor about steroid use.
03
Reduced blood flow to the nerve
The optic nerve needs a steady blood supply. Vascular disease and low perfusion pressure can damage nerve fibres even at modest eye pressure.
How it feels
Symptoms
Open-angle glaucoma is often silent. Angle-closure attacks are sudden and need urgent care.
01
Sudden or transient vision loss
A drop in vision, even if it comes and goes, can signal an acute pressure spike or nerve ischaemia.
02
Rainbow-coloured halos
Halos around lights, especially with ache and nausea, may mean corneal oedema from high pressure.
03
Double vision
Diplopia is less typical of chronic glaucoma but is recorded when present and investigated.
04
Intractable headaches
Severe brow or head pain with a red eye and vomiting is an emergency until angle closure is excluded.
05
Pupil abnormalities
Unequal pupils or a poorly reactive pupil can accompany acute glaucoma or nerve disease.
Treatment
Treatment aims to lower intraocular pressure and protect remaining nerve fibres. Care may include prescription drops, oral medicines, laser, surgery, or a combination, according to severity and the type of glaucoma. Vision already lost cannot be restored; the goal is to keep what remains.
Glaucoma services provided by us
01
Goldmann applanation tonometry
One of the most accurate methods used to measure intraocular pressure at the slit lamp.
02
Pachymetry
A simple, painless measurement of corneal thickness, which is needed to interpret pressure readings correctly.
03
Humphrey visual field analysis
The Humphrey field analyser maps the extent of the visual field so silent side-vision loss can be documented and followed.
04
OCT for ganglion cell complex and RNFL
Optical coherence tomography images and measures the ganglion cell complex and retinal nerve fibre layer without touching the eye.
05
Ultrasound biomicroscopy
UBM images the anterior segment when the angle, iris and ciliary body need to be seen in more detail.
06
Trabeculectomy surgery
A filtering operation that lowers pressure inside the eye. It remains a gold-standard surgical option in many patients.
07
Glaucoma valve surgery
A valved device opens to drain excess fluid from the eye to an external reservoir when further pressure lowering is required.
08
Glaucoma shunt surgery
A tube shunt provides an alternative drainage path when prior surgery has failed or the eye is at high risk.
09
Pediatric glaucoma surgery
Surgery in children most often uses external trabeculotomy or goniotomy, chosen according to the anatomy of the angle.
On-site equipment
How we assess glaucoma here
Tono-Pen
Handheld measurement of intraocular pressure that is quick and comfortable, including for children and post-operative eyes.
ZEISS CIRRUS 500 OCT
High-resolution scans of the optic nerve, RNFL and ganglion cell complex to detect and monitor glaucoma.
Forus fundus camera
Photographs the optic disc so cupping and disc haemorrhage can be compared visit to visit.
Slit lamp and anterior segment imaging
Examines the angle pathway and documents the front of the eye.
Appasamy YAG laser
Used when a laser opening in the iris is anatomically indicated as part of glaucoma care.
ZEISS LUMERA 300
Surgical microscope for glaucoma operations performed in this hospital.
Glaucoma FAQs
Questions patients ask
01What are the different types of glaucoma?
The main types are:
- Primary open-angle glaucoma
- Angle-closure glaucoma
- Congenital glaucoma
- Secondary glaucoma
02What are the risk factors for developing glaucoma?
Risk rises with age. Other factors include raised eye pressure, family history, diabetes, high or low blood pressure, thyroid disorder, eye injury, high refractive error and steroid use.
03What happens after shunt surgery for glaucoma?
Avoid activities that strain the eye for several weeks. Use a laxative if you are constipated, so you do not strain while passing stools.
04What is the success rate of glaucoma surgery?
Glaucoma surgery has about a 70 to 90 percent success rate for at least one year in older patients. Individual results depend on the type of glaucoma and previous surgery.
05How often should glaucoma be checked?
If you are above 40, you should be examined periodically, typically once a year, even if the eyes feel comfortable.
06Will my vision be restored after treatment?
Vision already lost from glaucoma is irreversible. Proper treatment can maintain remaining vision and slow further loss.
