Macular Hole
A macular hole is a full-thickness break in the macula, the central part of the retina responsible for sharp vision. It causes a dark spot and central vision loss that worsens without treatment. Learn the symptoms, causes, diagnosis and when surgical repair is required.

What a great experience! Very reassuring and I am very grateful for the consultation from Dr Musa he was so helpful in helping me make a decision to proceed to having eye correction surgery. I have the upmost confidence in him and the team at the Eye Doctor Clinic, Huddersfield.
Lozza 747I had implants with Dr Musa ten years ago. It was the best thing I've ever done. They are brilliant. My sight both near and distant was very poor but since the op I've had no glasses no lenses and my sight has been super. It remains really good to this day. Thank you Dr Musa. Brilliant consultations and treatment for glaucoma since.
Kay FitbitI can highly recommend the Eye Doctor Clinic, and I am so pleased I went there. Dr Musa, Gemma and Jess are lovely. They are very knowledgeable and were able to answer all my questions. My vision following surgery is great, and not having to wear glasses is fantastic.
Carol PeelWhat Is a Macular Hole?
A macular hole is a small but significant full-thickness break in the macula, the central part of the retina responsible for sharp, detailed vision. It causes a dark spot or gap in the centre of vision, making reading, recognising faces, and fine detail tasks increasingly difficult.
Macular holes most commonly develop in people over the age of 60, when the vitreous gel inside the eye shrinks and pulls away from the retina. In some cases, the traction created by this process tears through the central retina, forming a full-thickness hole. They may also occur in highly myopic eyes, following trauma, or as a complication of previous eye surgery.
A macular hole does not heal on its own and will typically enlarge over time without treatment. Surgical repair by vitrectomy with internal limiting membrane peel achieves hole closure in 85-95% of cases, with most patients experiencing meaningful improvement in central vision.
Symptoms of a Macular Hole
Symptoms affect central vision in one eye and typically worsen progressively. Peripheral vision is usually preserved. Early diagnosis and timely surgery offer the best chance of restoring meaningful central clarity.
Causes & Risk Factors
Macular holes develop when the central retina is disrupted by traction, stretching, or injury. Identifying the underlying cause guides surgical planning and helps assess the risk to the fellow eye.
Posterior Vitreous Detachment (PVD)
The most common cause. As the vitreous gel separates from the retina with age, it can pull on the macula and create a hole. A PVD is a normal part of ageing but where the adhesion to the macula is strong, the traction can tear through macular tissue.
Vitreomacular Traction (VMT)
When the vitreous does not fully separate from the macula, it exerts persistent pulling force on the central retina. This traction distorts the macula and, if sufficient, creates a full-thickness hole.
High Myopia (Short-Sightedness)
Severely myopic eyes are longer than normal, which stretches and thins the retina. This makes the macula more susceptible to hole formation, sometimes without any preceding vitreous traction.
Trauma
Blunt or penetrating eye injury can cause an acute macular hole. Traumatic holes are less common and may occur in younger patients, requiring the same surgical approach as age-related cases.
Retinal Detachment
A macular hole can progress to a retinal detachment, particularly in highly myopic eyes. A macular hole with associated retinal detachment requires urgent surgical repair to preserve vision.
Previous Eye Surgery
Cataract surgery and other intraocular procedures are occasionally associated with subsequent macular hole development as a surgical complication, particularly in eyes already at higher risk.
Diagnosis and Assessment
Diagnosis combines OCT imaging with clinical examination and functional testing to confirm the presence of the hole, establish its stage, and determine whether surgical repair is indicated. Early diagnosis gives the best surgical outcome.
OCT Imaging
Optical coherence tomography is the gold standard for diagnosing and staging macular holes. It shows the full-thickness break, measures hole size, and identifies any residual vitreous traction. OCT staging directly guides the surgical approach and informs prognosis.
Visual Acuity Testing
Visual acuity quantifies the degree of central vision loss. Patients with macular holes typically have reduced acuity, and the severity correlates broadly with hole size and duration. Acuity measurement monitors progression and assesses surgical outcomes.
Amsler Grid Assessment
The Amsler grid detects metamorphopsia (distortion of straight lines) and central scotoma (blind spot). These features are characteristic of a macular hole and help document the functional impact of the condition alongside OCT findings.
Fundus Examination
Dilated slit lamp biomicroscopy with a contact or non-contact lens directly visualises the macular hole. The surgeon assesses hole size, edge configuration, and any surrounding retinal changes to plan the optimal surgical technique.
When to Seek Advice
Seek a specialist assessment promptly if you notice any of the following:
- A dark or missing area has appeared in the central vision of one eye
- Straight lines appear bent or distorted (metamorphopsia)
- Reading or recognising faces has become noticeably more difficult
- Central vision has worsened over recent weeks or months
- New floaters or flashes appeared around the time symptoms started
- You are highly myopic and notice any sudden change in central vision
