What is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, which transmits visual information from the eye to the brain. Known as the “silent thief of sight,” glaucoma causes gradual, painless vision loss, often without early symptoms. The most common form, open-angle glaucoma, develops slowly and can lead to irreversible blindness if untreated.
Causes and Risk Factors
Glaucoma is mainly caused by increased intraocular pressure (IOP), but can also occur with normal IOP. Risk factors include:
-
Age over 40 years
-
Family history of glaucoma
-
African descent (higher prevalence in Nigeria)
-
Diabetes and hypertension
-
Eye trauma or prolonged steroid use
Symptoms of Glaucoma
Early glaucoma usually has no symptoms. Advanced glaucoma can cause:
-
Peripheral (side) vision loss
-
Tunnel vision in late stages
-
Sudden eye pain and redness in acute angle-closure glaucoma
Diagnosis at SpecSMART Eye Clinic Ikoyi
We use advanced diagnostic tools including:
-
Tonometry to measure eye pressure
-
Optical coherence tomography (OCT) for optic nerve imaging
-
Visual field testing for peripheral vision assessment
-
Slit-lamp examination and gonioscopy
Treatment Options
While vision lost to glaucoma cannot be restored, treatment can prevent further damage:
-
Prescription eye drops to lower IOP
-
Laser therapies such as trabeculoplasty
-
Surgery in advanced cases
Frequently Asked Questions (FAQs)
Q1: Can glaucoma be cured?
No, glaucoma cannot be cured, but early treatment can control eye pressure and prevent vision loss.
Q2: How often should I get screened?
If you are over 40 or have risk factors, get screened annually or as recommended by your eye doctor.
Q3: Is glaucoma hereditary?
Yes, family history increases your risk, so inform your doctor if glaucoma runs in your family.
Q4: Are eye drops the only treatment?
Eye drops are first-line treatment, but laser or surgery may be necessary if drops are insufficient.
