Headache Behind the Eye: Is It a Retinal Tear?
A headache behind the left eye can have many possible causes.
Common possibilities include:
- Migraine
- Sinus pressure
- Digital eye strain
- Uncorrected spectacle power
- Dry-eye disease
- Tension headache
- Cluster headache
A retinal tear is different because it usually affects vision rather than causing pain.
The one sign is important to look for is a headache with sudden flashes of light or floaters. It is not a normal headache behind the left eye; it is one of the clearest retinal tear symptoms.
This article brings insight from Dr Aman Kumar’s experience, a retina and cataract specialist at AKIO, on what causes a retinal tear, how it differs from an ordinary headache, and when a same-day examination is necessary.
Dr Aman Kumar explains:
A retinal tear usually does not announce itself through pain. A sudden change in vision is the warning sign patients should take seriously.
What Is a Retinal Tear?
Your eye is filled with a clear, gel-like substance called the vitreous, which is located against your retina.
As you age, this gel shrinks and pulls away, a process called posterior vitreous detachment.
Most of the time, nothing happens. The gel is sticky enough to tug a small piece of the retina along with it, creating a split, a retinal tear.
This is totally different from a retinal detachment, where the whole retina gets peeled off.
If fluid passes through that break and collects beneath the retina, the retina can separate from the eye wall. This is called a retinal detachment.
Retinal Tear vs Retinal Detachment
Feature | Retinal tear | Retinal detachment |
What happens | A break develops in the retina | Retina separates from the tissue beneath it |
Common symptoms | Flashes and new floaters | Flashes, floaters, shadow or curtain |
Central vision | May remain normal initially | May reduce if the macula becomes involved |
Treatment | Laser, cryotherapy or monitoring in selected cases | Retinal surgery is commonly required |
Urgency | Requires prompt specialist assessment | Medical eye emergency |
A retinal tear may be treatable before a retinal detachment develops, which is why early examination matters.
What Are the Symptoms of a Retinal Tear?
- Sudden flashes of light.
- A sudden increase in floaters (specks or cobwebs)
- A shadow or curtain at the edge of the vision.
- Blurred vision in the affected eye
- Sometimes no symptoms at all
- Usually painless, and not a headache condition
One study of over 1,000 patients found these symptoms stayed in one eye 92% of the time, split almost evenly left and right, a more reliable clue than which side of your head aches.

Does It Matter Whether the Headache Is Behind the Left Eye?
No. Headache behind the left eye does not reliably identify a retinal tear.
A retinal tear can occur in either eye. The more useful question is whether the visual symptoms are present in one eye or both.
Cover one eye and then the other.
If flashes, floaters, a shadow or reduced vision are present in only one eye, the symptom may be arising from that eye rather than from the visual-processing areas of the brain.
However, this home check cannot diagnose the cause. A dilated examination is still required.
What Causes a Retinal Tear?
- Posterior vitreous detachment, the vitreous gel shrinking and tugging on the retina as you age
- Any injury to the eye or head – Sports/falls/accidents can lead to tear/detachment
- Previous eye surgery like cataract surgery
- Previous retinal tear or detachment
- Lattice degeneration
- High myopia – the peripheral retina may be thinner and more vulnerable to tears.
What Are the Risk Factors for Retinal Tears?
- Getting older, since the vitreous naturally pulls away with age
- Myopia, or nearsightedness.
- A retina that has thinned with disease
- A family history of retinal tears or detachment
- Have undergone cataract surgery
- Have experienced eye trauma
- Had retinal detachment in the other eye
- Previously had a retinal tear
Can a Retinal Tear Cause Eye Pain?
Usually, no. The retina does not produce the type of pain associated with the cornea, eyelid or surface of the eye. Patients with a retinal tear commonly have:
- No redness
- No soreness
- No discharge
- No tenderness
- No headache caused directly by the tear
What Are the Common Complications of a Retinal Tear?
Retinal Detachment
- Fluid can pass through a retinal tear and collect beneath the retina, causing it to detach.
Vitreous Haemorrhage
A tear may damage a retinal blood vessel and cause bleeding into the vitreous.
Patients may notice:
- Hazy vision
- A shower of dark spots
- Red or black clouds
- Sudden reduction in vision
Permanent Vision Loss
A treated retinal tear often has a favourable outlook. Permanent visual loss is more likely if the tear progresses to retinal detachment and treatment is delayed, especially when the macula becomes involved.
How AKIO Treats Retinal Tear: Diagnosis and Treatment
At AK Institute of Ophthalmology, patients with sudden flashes, floaters or suspected retinal tears undergo specialist retinal evaluation
Assessment may include:
- Detailed symptom history
- Dilated peripheral retinal examination
- Retinal imaging when required
- Ultrasound when the retina cannot be viewed clearly
- Laser retinopexy when clinically indicated
- Follow-up for delayed tears or retinal detachment symptoms
- Led by Dr Atul Kumar, a Padma Shri awardee with 40+ years in retinal care and one of the best retina doctors in India, alongside Dr Aman Kumar, trained at AIIMS and PGIMER in retinal diagnosis and micro-incision surgery.
- This depth of experience makes AKIO one of the best retina hospitals in Delhi, and why patients seek a dedicated retina specialist in Delhi over a routine eye check.
How Urgently Should a Retinal Tear Be Checked?
New flashes, sudden floaters or a shadow in vision should be treated as an urgent concern.
Patients should try to seek prompt specialist evaluation, especially when symptoms are:
- Sudden
- Increasing
- Limited to one eye
- Associated with blurred vision
- Accompanied by a curtain or shadow
- Present after eye trauma
- Occurring in a highly myopic eye
Do not wait for a routine appointment several weeks later to see whether the symptoms disappear.
Complications and Side Effects of Treating a Retinal Tear
- A mild headache or eye ache for a day, usually eased with a standard over-the-counter painkiller
- Temporary soreness or grittiness.
- Increased cataract risk.
Conclusion
A retinal tear usually does not cause a headache behind the left eye, but sudden flashes, new floaters, blurred vision or a curtain-like shadow can signal a retinal tear or retinal detachment.
These symptoms are usually painless and should be examined urgently.
Patients can generally travel by train, road, or flight if coming from outside Delhi to seek specialised diagnosis and treatment of retinal tears and retinal detachment under Padmshri Dr Atul Kumar and AIIMS & PGI Gold Medalist Dr Aman Kumar at AKIO, Delhi.
Frequently Asked Questions
Are flashes and floaters always caused by a retinal tear?
No. They commonly occur with posterior vitreous detachment, which does not always tear the retina.
When Should I See a Retina Specialist?
As soon as you notice sudden flashes, new floaters, or a shadow at the edge of your vision, even in just one eye. Visit AKIO to get your retina examined by the retina experts.
Can I Prevent a Retinal Tear?
Not directly; keep up with dilated eye exams, especially if you are nearsighted, and wear protective eyewear during sports.
Can a Retinal Tear Be Self-Treated and Healed?
No. A retinal tear needs a retina specialist to seal it, with a laser or a freezing treatment. Very small, symptom-free tears are sometimes monitored rather than treated right away, but that call belongs to your specialist, not to you at home.
How Long Does It Take to Recover From Retinal Tear Repair?
Recovery from retinal tear treatment is faster than most people expect. You can usually go back to work and drive by the same day.
Is retinal laser painful?
Most patients tolerate it well. Bright lights, pressure or brief discomfort may occur. Numbing drops are used, and the experience varies with the tear’s location and amount of treatment.
Can an eye injury cause a delayed retinal tear?
Yes. Retinal tears may be detected immediately or develop after an interval following trauma.
Can stress cause a retinal tear?
No, Stress does not directly tear the retina
Can screen time cause a retinal tear?
Routine screen use does not directly cause retinal tears. It may contribute to eye strain, dryness or headache
Can I take flight/train/travel when I was diagnosed with a retinal tear or retinal detachment?
Yes, it’s completely safe to travel by flight/train/road to seek consultation if already diagnosed with retinal detachment or a retinal tear.
