Dr. Mohit Garg Explains: Early Signs of Retinal Detachment You Should Never Ignore
It often starts quietly. A few more floaters than usual. A brief flash of light at the edge of your vision when you turn your head. Easy to dismiss. Easy to ignore.
But for Dr. Mohit Garg, Co-Founder and Senior Vitreoretina Surgeon at Raahi Netradham, these subtle changes can be the earliest warning signs of retinal detachment—a sight-threatening condition that requires immediate medical attention.
Many patients wait until they notice a dark curtain, blurred vision, or sudden loss of sight. Unfortunately, by then, the retina may already have detached. Early diagnosis and timely treatment can make the difference between preserving vision and permanent vision loss.
In this guide, Dr. Mohit Garg explains what retinal detachment is, the early symptoms you should never ignore, who is at the highest risk, what retinal detachment surgery involves, and why acting quickly is critical for saving your eyesight.

Explained Simply
Your retina is a thin, light-sensitive layer that lines the back of your eye. Think of it as the film inside an old camera—it captures light and sends visual signals to your brain, allowing you to see clearly.
Retinal detachment occurs when this delicate layer separates from the blood vessels that supply it with oxygen and nutrients. Once detached, retinal cells begin to lose their function, causing blurred vision, dark shadows, or even permanent vision loss if treatment is delayed.
💬 From Dr. Mohit Garg
"In my years of operating on retinal detachments, the cases that stay with me are those who noticed the curtain coming down but waited, hoping it would improve. It never does. The sooner patients come in, the greater the chance we have of saving their central vision."
Retinal Tear vs Retinal Detachment — What's the Difference?
Although they are closely related, a retinal tear and a retinal detachment are not the same. A retinal tear is the earlier stage and can often be treated quickly with laser therapy. Once fluid passes through the tear and lifts the retina away from the back of the eye, it becomes a retinal detachment, which is a surgical emergency.
| Stage | What Happens | Urgency | Treatment |
|---|---|---|---|
| Retinal Tear | A small hole or rip develops in the retina before fluid gets underneath. | Within 24–48 Hours | Laser Treatment / Cryotherapy |
| Retinal Detachment | Fluid collects beneath the retina, causing it to separate from the eye wall. | Same-Day Emergency | Vitrectomy, Scleral Buckling or Pneumatic Retinopexy |
The Good News: A retinal tear diagnosed before it progresses to retinal detachment can often be treated with a quick laser procedure performed in the clinic. No hospital stay is usually required, and patients can often return home the same day. Early diagnosis dramatically reduces the need for emergency surgery.
The 5 Early Warning Signs of Retinal Detachment
Recognising these symptoms early can help preserve your vision. If you notice any of the following signs—especially if they appear suddenly—arrange an urgent retinal examination.
1. Sudden Shower of New Floaters
A sudden increase in floaters or the appearance of many new specks, threads or cobweb-like shapes may indicate that the vitreous gel has pulled on the retina, causing a retinal tear.
2. Flashes of Light
Bright flashes, particularly in your peripheral vision, occur when the vitreous tugs on the retina. New or repeated flashes should never be ignored.
3. A Dark Shadow or Curtain
A dark curtain or shadow spreading across your vision usually means retinal detachment has already begun. This requires immediate medical attention to maximise the chance of saving vision.
4. Sudden Blurred or Distorted Vision
Vision that suddenly becomes blurry, hazy or distorted in one eye may indicate that the retinal detachment is progressing toward the centre of vision.
5. Grey or Blurred Centre of Vision
If a grey patch or blurred area develops in the centre of your vision, the macula may already be involved. This is the most serious stage and requires emergency retinal surgery without delay.
Quick Reference: What Should You Do?
The action you should take depends on your symptoms. The earlier you seek treatment, the better the chances of preserving your eyesight.
| What You're Experiencing | Urgency | Recommended Action |
|---|---|---|
| A few floaters that haven't changed for months or years | Routine | Mention them at your next eye examination. |
| Sudden appearance of many new floaters | Urgent | Arrange a retinal examination within 24–48 hours. |
| New flashes of light in peripheral vision | Urgent | See a retina specialist within 24–48 hours. |
| New floaters together with flashes | Very Urgent | Visit an eye hospital or retina clinic today. |
| Dark curtain or shadow moving across vision | Emergency | Seek immediate retinal care the same day. |
| Sudden central blurring or grey patch in one eye | Emergency | Go immediately for emergency retinal evaluation. |
Who Is Most at Risk? Know Your Risk Factors
Retinal detachment can affect anyone, but some people have a much higher risk than others. If you belong to any of the groups below, regular retinal examinations are recommended—even if your vision seems perfectly normal.
- High myopia (short-sightedness greater than -6 diopters)
- Previous retinal detachment in one eye
- Family history of retinal detachment
- Past eye injury or trauma
- Recent cataract surgery
- Diabetes, especially if poorly controlled
- Age over 50 years
- Lattice degeneration or other retinal disorders
Especially for High Myopia Patients: If your spectacle power is -6.00D or higher, your retina is naturally thinner and more vulnerable to tears. Dr. Mohit Garg recommends a yearly dilated retina examination, even if you have no symptoms.
High-Risk Checklist
| High Myopia | ✓ Annual Retina Check |
|---|---|
| Age | 50+ Years |
| Eye Surgery | Recent Cataract Surgery |
| Medical History | Diabetes or Previous Retinal Tear |
| Family History | Retinal Detachment |
| Recommendation | Regular Dilated Retina Examination |
The Macula Rule — Why Every Hour Matters
The macula is the central part of the retina responsible for reading, recognising faces and seeing fine details. When retinal detachment occurs before the macula is affected (macula-on), surgery offers an excellent chance of restoring normal vision. Once the macula detaches (macula-off), permanent central vision loss becomes much more likely.
If you notice a curtain, shadow or sudden loss of vision, seek emergency retinal care immediately. A delay of even a few hours can significantly affect your final visual outcome.
| Stage | Expected Outcome |
|---|---|
| Macula-On | Excellent chance of near-normal vision after surgery. |
| Macula At Risk | Urgent surgery can still preserve central vision. |
| Macula-Off | Surgery can reattach the retina, but complete central vision recovery is often not possible. |

How Retinal Detachment Is Treated at Raahi Netradham
Every retinal detachment is different. The most appropriate treatment depends on the size, location, and severity of the detachment. Dr. Mohit Garg performs all three major retinal detachment procedures at Raahi Netradham and carefully explains the recommended approach before surgery.
| Surgical Technique | What It Involves | Best Suited For |
|---|---|---|
| Pneumatic Retinopexy | A small gas bubble is injected into the eye to gently push the detached retina back into position. The procedure is performed without a major operation in carefully selected patients. | Small retinal tears located in the upper part of the retina with limited detachment. |
| Scleral Buckling | A soft silicone band is placed around the outside of the eye to support the retinal wall and relieve traction on the tear. | Certain uncomplicated retinal detachments, particularly in younger patients. |
| Pars Plana Vitrectomy (PPV) | The vitreous gel is removed using advanced 25G or 27G micro-incision instruments before the retina is carefully repositioned and secured. | Most retinal detachments, complex cases, macula-off detachments and recurrent retinal detachments. |
