Glaucoma is a group of eye diseases that damage the optic nerve, the structure responsible for transmitting visual information from the eye to the brain. It is one of the leading causes of irreversible blindness worldwide.
Glaucoma often develops slowly and painlessly, which is why it is commonly known as the “Silent Thief of Sight.” In many cases, patients do not notice any symptoms until significant vision loss has already occurred.
At New Al Shefa Clinic, Dr. Ahmad Hossein Zadeh, Consultant Ophthalmologist with more than 30 years of experience, provides comprehensive glaucoma diagnosis and treatment using the latest medical, laser, and surgical technologies to preserve vision and prevent blindness.
Early glaucoma usually has no symptoms. As the disease progresses, patients may experience:
Because glaucoma can progress silently, regular eye examinations are essential, particularly for individuals at risk.
Open-angle glaucoma is the most common type of glaucoma. It usually affects both eyes and develops slowly over many years.
The drainage angle of the eye remains open, but the drainage system becomes less efficient, causing a gradual increase in intraocular pressure (IOP) and damage to the optic nerve.
Most patients are unaware of the disease until peripheral vision is affected.
Angle-closure glaucoma occurs when the drainage angle of the eye becomes blocked.
This condition may develop gradually or occur suddenly as an emergency. Symptoms may include:
Immediate treatment is essential to prevent permanent vision loss.
Congenital glaucoma is a rare condition present at birth or early childhood.
Symptoms may include:
Early diagnosis and surgery are essential to preserve vision.
In some patients, optic nerve damage occurs even though the eye pressure is within the normal range.
This condition is known as Normal Tension Glaucoma (NTG) or Low Tension Glaucoma and requires detailed evaluation of the optic nerve, visual fields, corneal thickness, and other risk factors.
Early diagnosis is crucial because significant vision loss can occur despite apparently normal eye pressure.
You may be at higher risk of developing glaucoma if you have:
If you have any of these risk factors, regular glaucoma screening is strongly recommended.
At New Al Shefa Clinic, glaucoma evaluation includes:
These tests help detect glaucoma early and monitor disease progression accurately.
Glaucoma eye drops are often the first line of treatment and help reduce eye pressure by either decreasing fluid production or improving fluid drainage.
Laser Peripheral Iridotomy (LPI) is a laser procedure used to treat or prevent angle-closure glaucoma.
A tiny opening is created in the iris using laser energy, allowing the fluid inside the eye to flow normally and preventing sudden increases in eye pressure.
LPI is a safe and effective outpatient procedure that usually takes only a few minutes.
Trabeculectomy remains the gold standard surgical treatment for advanced glaucoma.
The surgery creates a new drainage pathway for fluid to leave the eye, reducing intraocular pressure and slowing the progression of optic nerve damage.
The Ex-Press shunt is a miniature device that can be implanted during surgery to improve fluid drainage while maintaining excellent pressure control.
Selective Laser Trabeculoplasty (SLT) is an advanced and minimally invasive laser treatment for patients with open-angle glaucoma and ocular hypertension.
SLT uses low-energy laser pulses to stimulate the eye’s natural drainage system, improving fluid outflow and lowering eye pressure without damaging surrounding tissues.
The procedure:
SLT can be used as:
Many patients now choose SLT as an effective drop-free glaucoma treatment.
Direct Selective Laser Trabeculoplasty (Direct SLT) is one of the newest innovations in glaucoma care and represents the next generation of laser treatment for open-angle glaucoma and ocular hypertension.
Unlike conventional SLT, which requires a special contact lens to be placed on the eye, Direct SLT is a non-contact laser procedure that delivers laser energy directly to the trabecular meshwork without touching the eye.
This advanced technology improves patient comfort and shortens treatment time while effectively lowering intraocular pressure.
Advantages of Direct SLT
Direct SLT is considered one of the most recent technological advances in glaucoma treatment and offers patients a safe, effective, and convenient option for preserving vision.
Minimally Invasive Glaucoma Surgery (MIGS) is a group of modern surgical techniques designed to lower eye pressure with less tissue disruption and faster recovery than traditional glaucoma surgery.
MIGS procedures are especially suitable for patients with mild to moderate glaucoma and may be combined with cataract surgery.
Advantages include:
Ahmed Glaucoma Valve implantation is a highly effective surgical option for complex glaucoma cases.
This procedure is particularly useful in:
The Ahmed Valve helps regulate eye pressure by diverting fluid through a small drainage device implanted in the eye.
