Macular Hole in the Eye | Causes, Diagnosis, and Treatment  

A macular hole is a full‑thickness defect in the macula, which is part of the retina. When this happens, you may have trouble seeing clearly, especially with your central vision. Surgery to repair a macular hole has a high success rate, particularly when the hole is small.

What Is a Macular Hole?  

A macular hole is a true, full‑thickness opening in the macula, the central part of the retina. The retina is the light‑sensitive layer at the back of your eye that contains nerve cells which respond to light and allow you to see.  

A macular hole usually develops in one eye, although it can affect both. In the center of the retina (the macula), the nerve cells are packed very closely together.  

Sometimes the gel‑like substance that fills your eye, called the vitreous, changes consistency. As it shrinks, it can pull on the central macula and create a macular hole.  

A macular hole can affect your vision in several ways, but it primarily impairs your central vision (the objects you see straight ahead). This can interfere with activities such as driving and reading.

How Common Is a Macular Hole?  

One U.S. study estimates that the annual incidence of macular holes is about 7.8 cases per 100,000 people. The condition is more common in women and people assigned female at birth (AFAB). It occurs more frequently in individuals aged 55 and older, but it can develop at any age.

Are There Different Types of Macular Holes?  

Macular holes can be primary or secondary.  

– A primary macular hole develops without a history of eye injury and is not caused by another underlying medical condition.  

– A secondary macular hole occurs along with, or as a result of, another disease or condition, such as trauma or eye inflammation (uveitis).  

Ophthalmologists use two main grading systems to classify macular holes. One system has four stages, with stage 1 being the least severe and stage 4 the most advanced. A newer system classifies macular holes into three stages based on imaging findings.  

Your eye‑care provider will explain which stage you have and how severe your macular hole is.

What Are the Symptoms of a Macular Hole?  

Early symptoms of a macular hole may include:  

– Blurred or distorted central vision.  

– Difficulty reading or seeing fine details.  

– A dark or gray spot in the center of your vision.  

– Straight lines appearing bent, wavy, or broken (metamorphopsia).  

When a macular hole causes these symptoms, they appear in the eye that has the hole. If you notice any of these changes, it’s important to schedule an appointment with your eye‑care provider as soon as possible.  

What Causes a Macular Hole?  

In most people, macular holes are caused by vitreomacular traction, which is more likely to occur as you age. As the vitreous gel naturally shrinks and separates from the retina, it can pull on the macula and create a hole.  

A macular hole can also develop after an eye injury or due to certain eye conditions, including high (pathologic) myopia.  

You may have a higher risk of developing a macular hole if you have:  

– Age‑related changes in the vitreous gel.  

– Significant myopia (high degree of nearsightedness).  

– A history of retinal tears or detachment.  

– Previous eye surgery or trauma.  

What Are the Risk Factors for Developing a Macular Hole?  

Risk factors for macular holes include:  

– Age over 55.  

– Female sex / AFAB status.  

– High myopia.  

– Previous macular hole in the other eye.  

– Eye trauma.  

– Certain retinal diseases or inflammation (such as uveitis).  

– History of retinal detachment or retinal surgery.  

What Are the Complications of a Macular Hole?  

If a macular hole is left untreated, the following complications may occur:  

– Progressive loss of central vision.  

– Severe difficulty with reading, driving, and detailed work.  

– Permanent central vision damage if the hole remains open for a long time.  

– Reduced quality of life due to visual impairment.  

What Tests Are Used to Diagnose a Macular Hole?  

Your ophthalmologist will likely order one or more of the following tests to evaluate your retina:  

– Dilated eye examination with fundoscopy to directly view the macula.  

– Optical coherence tomography (OCT) to obtain high‑resolution cross‑sectional images of the retina and measure the size and depth of the hole.  

– Visual acuity testing to assess how clearly you can see.  

– Amsler grid testing to detect central vision distortion or blind spots.  

Treatment for Macular Hole  

The most common treatment for a macular hole is a surgical procedure called a vitrectomy. During a vitrectomy, a retina specialist removes the vitreous gel from your eye.  

Your surgeon, an ophthalmologist trained in retinal surgery, may also remove any membranes or scar‑like tissue that are exerting traction on the macula. Then a sterile gas bubble is injected into the eye to gently press against the macula and keep the hole closed while it heals.  

You may need to maintain a face‑down position for one to seven days to keep the gas bubble in the correct place over the hole.  

If the macular hole is small and in an early stage, your retina specialist may recommend careful observation instead of immediate surgery. In some early cases, a macular hole can close on its own.
