5 Myths About Retina Injections Debunked

What Every Patient Should Know Before Saying "No" to Treatment

By Dr. Shantanu Gupta Cataract & Medical Retina Specialist Shantanu Netralaya Eye Hospital, Varanasi

Every week at Shantanu Netralaya Eye Hospital, Varanasi, I meet patients who have been advised to undergo a retina injection but are understandably anxious.

Many tell me:

"Doctor, someone said the injection can make me blind."

"I've heard it's extremely painful."

"If I take one injection, will I need them for life?"

These concerns are common, but many are based on myths rather than facts. Retina injections, also called intravitreal injections, have transformed the treatment of several sight-threatening eye diseases and have helped millions of people preserve their vision.

Let's separate fact from fiction.

Myth 1: Retina Injections Are Extremely Painful

Truth: Most patients experience only mild discomfort.

This is the most common fear I hear.

Before the injection, we numb the eye using anesthetic eye drops. The procedure usually takes only a few minutes, and the actual injection lasts just a few seconds.

Most patients describe the sensation as slight pressure rather than pain.

After the procedure, you may experience mild irritation, watering, or a gritty sensation for a day or two, which usually settles quickly.

The fear is often much greater than the actual experience.

Myth 2: Retina Injections Can Cause Blindness

Truth: Retina injections are performed to prevent vision loss—not cause it.

Conditions such as:

Diabetic macular edema Wet age-related macular degeneration (AMD) Retinal vein occlusion Certain cases of myopic choroidal neovascularization

Modern anti-VEGF medications help reduce leakage, swelling, and abnormal blood vessel growth inside the eye.

Like any medical procedure, retina injections carry small risks, including infection or retinal detachment, but these complications are rare. The benefits generally far outweigh the risks when treatment is recommended by a retina specialist.

Myth 3: One Injection Will Cure the Disease Forever

Truth: Most retinal diseases require ongoing monitoring and sometimes repeated treatment.

Many retinal conditions are chronic, much like diabetes or high blood pressure.

The number of injections varies depending on:

Your diagnosis Disease severity Response to treatment OCT scan findings Vision changes

Some patients need only a few injections, while others may require treatment over a longer period with gradually increasing intervals.

Your treatment plan is individualized—not every patient follows the same schedule.

Myth 4: If My Vision Improves, I Can Stop Follow-Up Visits

Truth: Improvement does not always mean the disease is gone.

Many retinal diseases can become active again without obvious symptoms.

Even if your vision feels normal, swelling or abnormal blood vessels may return.

Regular follow-up appointments and OCT scans help detect recurrence early, allowing treatment before permanent damage occurs.

Skipping follow-up visits may result in avoidable vision loss.

Myth 5: Retina Injections Are Only for Elderly Patients

Truth: Patients of many different ages may need retina injections.

Although age-related macular degeneration affects older adults, retina injections are also used for:

Diabetes-related retinal diseases Retinal vein occlusions Pathological myopia Certain inflammatory eye conditions Some retinal complications after surgery

Age alone does not determine whether someone needs an injection.

What Happens During a Retina Injection?

The procedure is usually straightforward:

Your vision and eye pressure are checked. The eye is cleaned thoroughly to reduce infection risk. Numbing drops are applied. The medication is injected into the vitreous cavity. You rest briefly before going home.

Most patients return home the same day.

When Should You Contact Your Eye Doctor After an Injection?

Mild redness and irritation are common.

However, seek urgent medical attention if you experience:

Severe eye pain Sudden vision loss Increasing redness Pus-like discharge Persistent flashes or a shower of new floaters Extreme sensitivity to light

These symptoms are uncommon but require immediate evaluation.

Frequently Asked Questions Are retina injections safe?

Yes. When performed under sterile conditions by an experienced retina specialist, retina injections have an excellent safety record.

Will I need an injection every month forever?

Not necessarily. Treatment frequency depends on your eye condition and how well it responds. Many patients eventually require injections less often.

Can I go home after the procedure?

Yes. Most patients return home shortly after the injection. You may be advised not to drive yourself immediately afterward.

Can diabetic patients safely receive retina injections?

Yes. Anti-VEGF injections are one of the most effective treatments for diabetic macular edema and other diabetic retinal conditions.

Can I continue my regular medicines?

Most routine medications can be continued, but always inform your retina specialist about blood thinners, allergies, or any recent illness.

Dr. Shantanu Gupta's Advice

Retina injections have changed the lives of countless patients by preserving vision that might otherwise have been lost.

Don't let myths or misinformation delay treatment. Early diagnosis, timely injections, and regular follow-up offer the best chance of maintaining good vision.

If you have been advised to undergo a retina injection and have questions, discuss them openly with your eye specialist. Understanding your treatment can help you make informed decisions with confidence.
