What are anti-VEGF injections?

Anti-VEGF (anti-vascular endothelial growth factor) medication is injected directly into the eye to block a protein that causes abnormal blood vessel growth and leakage in the retina. It is one of the most effective treatments available for several sight-threatening retinal conditions.

Who needs this treatment

• Wet age-related macular degeneration
• Diabetic macular edema
• Retinal vein occlusion with macular swelling
• Certain cases of diabetic retinopathy with abnormal vessel growth

What the procedure involves

The injection is given in-clinic under topical anaesthetic drops, so the eye is numbed beforehand. The needle used is very fine, and the injection itself takes only a few seconds. Most patients describe mild pressure rather than sharp pain, and are able to go home the same day with no downtime required.

What to expect afterward

It is normal to notice some redness, mild grittiness or small floating spots in the vision for a day or two after the injection. Vision improvement is often gradual rather than immediate, and treatment is typically given as a course of several injections spaced weeks apart, followed by OCT monitoring to guide how often further doses are needed.

Key takeaway

Anti-VEGF therapy is a well-established, closely monitored treatment — and for many retinal conditions, it is the most effective way to preserve and even improve vision when started early.

What is OCT?

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to capture detailed, cross-sectional pictures of the retina — the light-sensitive tissue at the back of the eye. It works much like an ultrasound, but uses light instead of sound, producing images with micrometre-level detail in just a few seconds.

Why it matters

A standard eye exam can show the surface of the retina, but OCT reveals its individual layers — including fluid, swelling or thinning that is not visible to the naked eye. This makes it one of the most useful tools for catching retinal disease early, often before a patient notices any change in vision.

Conditions OCT helps diagnose and monitor

• Diabetic macular edema — swelling in the macula from diabetic eye disease
• Age-related macular degeneration — both the dry and wet forms
• Macular holes and epiretinal membranes
• Response to anti-VEGF injections over time
• Glaucoma-related changes to the optic nerve

What to expect during the scan

OCT is quick, painless and requires no needles or injections. Patients rest their chin on a support while the machine captures images of the retina, usually while the pupils are dilated for the clearest view. Most scans take under 10 minutes, and results are available the same visit.

Key takeaway

OCT gives Dr. Abir a detailed, layer-by-layer view of the retina — turning what would otherwise be invisible changes into clear, trackable data that guides treatment decisions.

Right after the procedure

It’s normal to experience mild discomfort, light sensitivity or blurry vision in the first day or two after cataract or retinal surgery. Rest, avoid rubbing or pressing on the treated eye, and protect it as advised — Dr. Abir’s team will give you eye-specific instructions based on the exact procedure performed.

Using prescribed eye drops correctly

Eye drops after surgery help prevent infection, control inflammation and support healing. Wash your hands before each use, follow the prescribed schedule closely, and avoid stopping early even if your eye feels comfortable — inflammation can still be present beneath the surface.

Activities to avoid during recovery

• Swimming or exposing the eye to unclean water
• Heavy lifting or strenuous exercise
• Dusty, smoky or windy environments without protective eyewear
• Rubbing or pressing on the operated eye

When to contact the practice

• Increasing pain rather than gradual improvement
• Sudden decrease in vision
• Unusual discharge, redness or swelling
• Any symptom that feels concerning or unexpected

Key takeaway

Most recovery after modern cataract and retinal procedures is straightforward when aftercare instructions are followed closely — and prompt follow-up appointments help catch any issues early.

The retina’s role in vision

The retina is the light-sensitive layer at the back of the eye responsible for capturing images and sending them to the brain. Because it plays such a central role in vision, problems affecting the retina can progress quickly and sometimes require urgent attention.

Warning signs that shouldn’t wait

• Sudden flashes of light in one or both eyes
• A sudden increase in floaters, or floaters accompanied by flashes
• A dark curtain or shadow appearing in your field of vision
• Sudden blurred or distorted vision, especially straight lines appearing wavy
• Sudden, painless vision loss in one eye

Who should consider routine retina checkups

• People with diabetes, regardless of symptoms
• Those with high myopia (severe short-sightedness)
• Anyone with a family history of retinal disease
• Adults over 50, particularly with concerns about age-related macular changes

What to expect at a retina consultation

A retina evaluation typically includes a dilated eye examination and OCT (optical coherence tomography) imaging, which provides a detailed cross-sectional view of the retina and macula. This helps identify fluid, swelling or structural changes that aren’t visible on a standard eye check.

Key takeaway

Sudden flashes, new floaters or a shadow in your vision are signs to seek retina care promptly rather than waiting for your next routine appointment.

What is diabetic retinopathy?

Diabetic retinopathy is damage to the blood vessels of the retina caused by prolonged high blood sugar levels. Over time, these vessels can leak, swell or grow abnormally, affecting the retina’s ability to send clear images to the brain. It is one of the leading causes of preventable vision loss among adults with diabetes.

Why regular screening matters

In its early stages, diabetic retinopathy often causes no noticeable symptoms — vision can still feel normal even as changes are occurring in the retina. This is why routine retinal screening, rather than waiting for symptoms, is essential for anyone living with diabetes, regardless of how well blood sugar is controlled.

Stages of the condition

• Non-proliferative diabetic retinopathy (NPDR) — early stage, with weakened and leaking blood vessels
• Proliferative diabetic retinopathy (PDR) — advanced stage, with abnormal new vessel growth that carries a higher risk of bleeding and vision loss
• Diabetic macular edema — swelling in the macula, which can occur at any stage and directly affects sharp, central vision

Treatment options

Depending on the stage and severity, treatment may include tighter blood sugar control, laser photocoagulation to stabilise abnormal vessels, or intravitreal anti-VEGF injections to reduce swelling and slow disease progression. OCT imaging is used to track the macula closely and guide treatment decisions over time.

Key takeaway

If you have diabetes, an annual dilated retinal examination — even with no symptoms — is one of the most effective ways to protect your long-term vision.

What is a cataract?

A cataract is a clouding of the eye’s natural lens, the clear structure that helps focus light onto the retina. As the lens becomes cloudy, vision gradually turns blurry, hazy or less colourful. Cataracts most often develop slowly with age, though they can also form earlier due to injury, certain medications, diabetes or prolonged UV exposure.

Common symptoms

• Blurry, cloudy or dim vision
• Increased sensitivity to glare, especially from headlights at night
• Colours appearing faded or yellowed
• Frequent changes in eyeglass or contact lens prescription
• Difficulty seeing well at night

When does surgery become necessary?

Not every cataract needs immediate surgery. In the early stages, a change in glasses prescription or better lighting may be enough. Surgery is generally recommended once the cataract starts interfering with daily activities — reading, driving, recognising faces or working comfortably.

There is no medical benefit to waiting once vision is significantly affected; cataracts do not resolve on their own, and delaying treatment only prolongs reduced quality of life.

What modern cataract surgery looks like

Cataract surgery today is typically done as phacoemulsification — a small-incision procedure that removes the cloudy lens and replaces it with a clear intraocular lens (IOL). Dr. Abir performs an injection-free, bandage-free, topical anaesthesia approach in appropriately selected patients, which allows for a more comfortable procedure and faster visual recovery for many patients.

Key takeaway

A cataract diagnosis isn’t an emergency, but it is worth having your vision assessed regularly so treatment can be planned at the right time — before it meaningfully affects your daily life.
