A macular hole is a small, full-thickness break in the macula, the central part of the retina responsible for sharp, detailed vision. It is one of the more common causes of sudden distortion in central vision, a straight line that looks wavy, or a face that looks partly warped when viewed directly, and, when identified early through an eye examination, one of the more treatable retinal conditions.
What Is a Macular Hole?
The macula is in the centre of the retina and is responsible for providing detailed vision for –
- reading,
- recognising a face,
- threading a needle.
- Driving
A macular hole is an opening that develops in this central retinal tissue.
Because the macula controls whatever you are looking directly at, even a relatively small hole can produce very noticeable distortion.
Patients may notice that:
- A door frame looks bent
- Tiles or straight lines appear wavy
- Letters look broken or missing
- Part of someone’s face appears distorted
- A small blurred or blank spot develops in the centre of vision
What Causes a Macular Hole?
Most macular holes are age-related. The vitreous, a gel that fills the back of the eye, normally separates cleanly from the retina as it shrinks with age. When it stays attached to the macula for longer than elsewhere, the resulting pull, called vitreomacular traction, can open a hole.
- Age-related vitreous separation (the most common cause)
- High myopia (significant short-sightedness)
- A direct eye injury
- An epiretinal membrane (a thin layer of scar tissue on the retina’s surface)
- Long-standing swelling from diabetic eye disease
Macular holes are also more common in women, usually in their 60s or 70s, according to NCBI’s StatPearls clinical reference.
Ways to Perform Diagnosis of a Macular Hole
- Detailed symptom history and a standard visual acuity test
- Amsler grid test, a simple printed grid that reveals distortion or a missing area in central vision
- Dilated fundus examination, a direct view of the macula through the pupil
- Optical coherence tomography (OCT), a cross-sectional retinal scan that confirms the hole and measures it, classifying it as small, medium, or large under the International Vitreomacular Traction Study Group system (Ophthalmology, 2013); this classification guides the treatment plan
What Are the Common Symptoms of Having a Macular Hole?
- Blurred or distorted central vision
- A grey, dark, or blank patch at the centre of vision
- Difficulty reading, recognising faces, or doing close-up work
- Straight lines or text appearing to bend near the centre of the page
- Gradual worsening over days to weeks, rather than a sudden blackout
- Usually affects one eye at a time
Is a Macular Hole the Same as Macular Degeneration?
No.
Both affect the macula and can cause distorted central vision, but they are different conditions.
A macular hole is a physical opening in the central retina.
Age-related macular degeneration (AMD) involves degenerative changes affecting the macula.
A retinal scan helps distinguish between these and other causes of distorted central vision.
What Is Macular Hole Surgery?
The standard operation is a pars plana vitrectomy.
During surgery, the retina surgeon generally:
- Removes the vitreous gel that is causing or contributing to traction.
- Peels the internal limiting membrane (ILM) around the macula to release microscopic traction.
- Places a gas bubble inside the eye to support the macula while the hole heals.
A 2025 international Asia-Pacific consensus describes pars plana vitrectomy with ILM peeling and gas tamponade as the standard surgical approach for full-thickness macular holes.
AKIO’s retina team in Delhi, led by Dr. Atul Kumar, Padma Shri Awardee, former Chief of the Dr RP Centre at AIIMS, with over 4 decades of retina experience, evaluates macular hole cases through his expertise.
He is known as the “Father of Macular Hole” in India.
Dr Aman Kumar is a Senior Consultant Vitreo-Retinal and Cataract Surgeon at AKIO, an AIIMS New Delhi alumnus and PGIMER Chandigarh Gold Medallist, with expertise in macular disorders and vitreoretinal surgery.

Conclusion
If straight lines look bent, text appears distorted or faces look warped in the centre, do not assume it is simply a change in glasses power.
A macular hole affects the part of the retina responsible for detailed central vision, and an OCT scan can usually identify it quickly.
Many macular holes can be successfully closed with modern vitreoretinal surgery, and earlier treatment generally offers better prospects for visual recovery.
Frequently Asked Questions
Can a macular hole heal on its own?
Some small, early full-thickness macular holes may close spontaneously; however, most holes require to be operated. Thus, a retina consultation is essential.
Does a macular hole cause total blindness?
A macular hole affects central vision for fine detail, while peripheral vision stays normal.
What is recovery like after macular hole surgery?
Most patients need a period of face-down positioning after surgery; your surgeon will confirm exactly how long, since it depends on the condition.
Can a macular hole go away after treatment?
Surgery closes most macular holes. Full recovery of central vision takes weeks.
Can I fly after macular hole surgery?
Not while an intraocular gas bubble remains. You must wait until your retina surgeon confirms that the gas bubble has completely disappeared.
Can macular holes affect both eyes?
Yes, although they commonly begin in one eye. Patients who have had a macular hole in one eye have an increased risk of developing one in the other eye.
