Symptoms

Glaucoma symptoms vary depending on the type and stage of the disease. It often develops slowly and painlessly, especially in its most common form—open-angle glaucoma—making regular eye check-ups essential.

🔹 1. Open-Angle Glaucoma (Most Common Type)

• No symptoms in early stages
• Gradual loss of side (peripheral) vision
• Blurred vision in late stages
• “Tunnel vision” in advanced cases

🔹 2. Angle-Closure Glaucoma (Sudden & Severe)

• Sudden severe eye pain
• Redness of the eye
• Blurred or sudden vision loss
• Halos around lights
• Nausea and vomiting

⚠️ This is a medical emergency. Immediate treatment is required.

🔹 3. Normal-Tension Glaucoma

• Progressive vision loss despite normal eye pressure
• Often asymptomatic until noticeable vision problems arise

🔹 4. Congenital Glaucoma (In Infants)

• Enlarged or cloudy eyes
• Frequent tearing
• Light sensitivity (photophobia)
• Poor vision or abnormal eye movement

⚠️ When to Get Checked

• Family history of glaucoma
• Age over 40
• Chronic diseases like diabetes, hypertension
• Vision loss, eye pressure, or unusual eye symptoms

Risk Factors

Glaucoma can affect anyone, but certain individuals are at higher risk. Knowing these risk factors helps with early detection and prevention of vision loss.

🧬 1. Family History

• Glaucoma is often hereditary
• Having a parent or sibling with glaucoma significantly increases your risk

👴 2. Age

• Risk increases after age 40
• Especially common in people over 60

👁️ 3. High Intraocular Pressure (IOP)

• Elevated eye pressure is the strongest risk factor
• Can damage the optic nerve if not managed

🧑🏽‍⚕️ 4. Medical Conditions

• Diabetes
• High blood pressure (hypertension)
• Heart disease
• Migraines

👓 5. Eye Conditions

• High myopia (nearsightedness)
• Thin corneas
• Previous eye injury or surgery
• Retinal detachment

🌍 6. Ethnicity

• African descent – higher risk and earlier onset
• Asians – higher risk of angle-closure glaucoma
• Hispanics – increased risk after age 60

💊 7. Long-Term Corticosteroid Use

• Eye drops, pills, or injections containing steroids can raise IOP

👶 8. Congenital Factors

• Some babies are born with underdeveloped drainage systems, leading to congenital glaucoma

🧑‍💻 9. Lifestyle & Other Risks

• Prolonged screen time or eye strain (doesn’t cause glaucoma but can mask symptoms)
• Smoking, poor nutrition, and lack of eye check-ups

Preparation for Glaucoma Surgery

Preparing well for glaucoma surgery helps reduce complications and ensures a smooth recovery. Here’s a detailed step-by-step guide:

🔍 1. Pre-Surgery Eye Examination

• Comprehensive evaluation by an ophthalmologist
• Tests may include:
  • Intraocular pressure (IOP) measurement
  • Visual field test
  • Optic nerve imaging (OCT)
  • Corneal thickness and drainage angle exam

💊 2. Review of Medications

• Inform your doctor about all current medications, especially:
  • Blood thinners (may need to stop temporarily)
  • Diabetes or blood pressure medications
• Continue using prescribed glaucoma eye drops unless told otherwise

🚫 3. Stop Using Contact Lenses

• Stop using contact lenses 1 week before surgery if applicable
• Helps cornea return to natural shape

🍽️ 4. Fasting (if advised)

• Some types of surgery (especially under general anesthesia) may require fasting 6–8 hours before
• Ask your doctor if this applies to you

🧴 5. Personal Hygiene & Eye Care

• Clean your face and eyelids gently the night before and morning of surgery
• Avoid makeup, creams, perfumes, or lotions on surgery day

🚖 6. Arrange Transportation

• You will not be able to drive after the procedure
• Have a friend or family member accompany you

📃 7. Pre-Surgical Instructions

• Follow your surgeon’s written instructions carefully
• You may receive pre-surgery antibiotics or eye drops to prevent infection

🧘 8. Mentally Prepare

• Surgery usually takes 30–60 minutes
• You’ll likely be awake (local anesthesia) but relaxed
• Ask your doctor any questions in advance to feel more at ease

Procedure

Glaucoma surgery is performed to lower intraocular pressure (IOP) and prevent further damage to the optic nerve. The type of surgery depends on the severity and form of glaucoma. Here’s how the most common surgeries are typically performed:

👁️‍🗨️ 1. Trabeculectomy (Most Common Traditional Surgery)

🔬 Step-by-Step:

1. Local anesthesia is administered to numb the eye.
2. A small incision is made in the white of the eye (sclera).
3. A tiny flap is created in the sclera and a new drainage pathway is formed to allow excess fluid to leave the eye.
4. A filtering bleb (fluid bubble) forms under the conjunctiva (the eye’s outer layer).
5. The flap is partially closed to control the flow and prevent over-drainage.

⏱ Duration: 30–60 minutes

🧷 Hospital stay: Usually day-care or 1 night

⚡ 2. Laser Trabeculoplasty (e.g., SLT or ALT)

🔬 Step-by-Step:

1. Performed in an outpatient clinic.
2. A special laser is aimed at the trabecular meshwork, which is the eye’s natural drainage system.
3. The laser improves fluid outflow, lowering IOP.

⏱ Duration: 10–15 minutes

🏠 Same-day return home

💧 3. Glaucoma Drainage Implant Surgery (Tube Shunt Surgery)

🔬 Step-by-Step:

1. A tiny tube is inserted into the front of the eye.
2. The tube is connected to a small plate (reservoir) placed on the eye’s surface under the conjunctiva.
3. The tube drains excess fluid into the reservoir where it is absorbed gradually.

Used for:

• Complex or severe glaucoma
• Failed previous surgeries

🧪 4. Minimally Invasive Glaucoma Surgery (MIGS)

🔬 Step-by-Step:

1. Performed through a small incision (often with cataract surgery).
2. Uses tiny stents or microscopic devices (e.g., iStent, XEN Gel Stent) to improve fluid outflow.

⏱ Duration: 15–30 minutes

✅ Fastest recovery, fewer complications

⚠️ 5. Laser Iridotomy (for Angle-Closure Glaucoma)

🔬 Step-by-Step:

1. A laser is used to create a small hole in the iris.
2. This hole allows fluid to flow freely between eye chambers, reducing pressure.

⏱ Duration: 5–10 minutes

💡 Quick outpatient procedure
