What is a Macular Hole?
The macula is the small but vital central area of the retina responsible for the sharp, detailed vision needed for everyday tasks such as reading, driving, and recognising faces.
A macular hole develops when the vitreous gel inside the eye gradually shrinks with age and exerts traction on the macula, eventually creating a small tear or break in this delicate tissue. This disrupts central vision, causing distortion or a dark spot at the centre of the visual field.
Unlike age-related macular degeneration (AMD), a macular hole can often be successfully repaired with surgery — making early diagnosis and timely intervention essential to achieving the best possible visual outcome.
Who Is a Candidate for Macular Hole Vitrectomy?
Not all macular holes require immediate surgical intervention, and candidacy for vitrectomy is assessed on an individual basis. Dr Bobby Cheng will conduct a thorough evaluation to determine whether surgery is appropriate and, if so, the optimal timing to achieve the best possible outcome.
Vitrectomy surgery may be recommended when the following criteria are met:
- Symptomatic central vision loss — Distorted or blurred central vision that meaningfully interferes with everyday activities such as reading, recognising faces, or driving.
- Confirmed macular hole on OCT imaging — A full-thickness macular hole has been identified and characterised on Optical Coherence Tomography scanning.
- Hole size and stage — The size and stage of the hole suggest that surgical repair is likely to improve or stabilise vision.
- Suitable overall health — Your general eye health and medical condition are appropriate for surgery.
In general, smaller and more recently formed macular holes tend to achieve higher closure rates following vitrectomy. Larger or longer-standing holes may still benefit from surgery, though visual outcomes can be less predictable.
A comprehensive consultation with Dr Bobby Cheng is the important first step in determining whether vitrectomy is right for you and planning the most appropriate course of treatment.
Symptoms of a Macular Hole
Macular hole symptoms are confined to central vision; peripheral or side vision is typically unaffected. Symptoms may develop gradually or become noticeable quite suddenly. Common signs include:
Blurred or distorted central vision
A general reduction in the clarity of central sight, often first noticed during tasks requiring focused attention such as reading or using a smartphone.
Straight Lines Appearing Bent or Wavy (Metamorphopsia)
A distinctive symptom caused by displacement of the macula’s photoreceptor cells, making regular lines — such as text, door frames, or ruled paper — appear curved or irregular.
A dark or empty spot in the centre of sight
As the macular hole enlarges, a central scotoma — a gap or blank area — may develop at the focal point of sight.
Difficulty reading or recognising faces
The progressive loss of central visual acuity makes fine-detail tasks increasingly difficult and can significantly affect quality of life and independence.
How is a Macular Hole Diagnosed?
Accurate diagnosis of a macular hole requires a thorough clinical assessment combined with advanced retinal imaging. A comprehensive evaluation typically includes:
Measures the clarity and sharpness of your central vision at various distances, providing a baseline assessment of how the macular hole is affecting your sight.
A simple but effective test in which patients view a grid of straight lines. Distortion, waviness, or missing areas within the grid may indicate changes to the macula and help detect early symptoms of a macular hole.
The gold standard imaging tool for macular hole diagnosis. OCT produces high-resolution, cross-sectional images of the macula, allowing your specialist to confirm the presence of a hole, assess its size and stage, and determine the most appropriate course of treatment.
A macular hole can significantly affect central vision, but timely vitrectomy surgery in Singapore can help improve clarity and reduce distortion.
Early treatment offers the best chance for successful closure. We provide personalised care for patients seeking vitrectomy surgery in Singapore, with support from diagnosis through to recovery.
Vitrectomy Surgery for Macular Hole
Vitrectomy is the primary and most effective treatment for macular holes. It is a delicate microsurgical procedure designed to relieve the traction pulling on the macula, allowing the tissue to close and heal naturally. The surgery is typically performed as a day procedure under monitored sedation or general anaesthesia, with most patients returning home the same day.
Anaesthetic eye drops and injections are administered to ensure comfort throughout the procedure. The eye is gently cleaned and a small speculum is placed to keep the eyelids open.
Tiny microincisions are made in the white of the eye, through which fine surgical instruments are carefully inserted. The vitreous gel — which is responsible for exerting traction on the macula — is gently removed, relieving the pulling forces on the central retina.
A thin membrane on the surface of the retina — known as the inner limiting membrane — will be carefully peeled away to further reduce traction and significantly improve the likelihood of macular hole closure. A specialised surgical dye is sometimes applied to make the membrane more visible during peeling.
A small gas bubble is introduced into the vitreous cavity. The bubble floats upward and gently presses against the macula, holding the edges of the hole together to support healing and closure.
Following surgery, patients are typically advised to maintain a face-down position for a prescribed period — usually several days to weeks. This ensures that the gas bubble remains in contact with the macula and provides optimal support during the healing phase. The exact duration depends on the size and stage of the hole.
The gas bubble dissolves naturally over the course of several weeks. During this period, vision is often temporarily blurred as the bubble gradually clears. As the macula heals and closes, many patients experience progressive improvement in their central vision over the following weeks to months.
What to Expect After Macula Hole Surgery
Recovery following vitrectomy surgery for a macular hole is a gradual process. Understanding what to expect helps patients navigate the healing period with confidence.
Visual improvement is typically gradual and may continue over several months. As the gas bubble dissolves and the macula heals, most patients notice a progressive reduction in distortion and an improvement in central visual clarity. The extent of recovery depends on the size of the hole and how long it was present before surgery.
While the gas bubble remains in the eye, certain activities and procedures are not permitted:
- Air travel and high-altitude travel must be avoided, as changes in atmospheric pressure can cause the gas to expand and raise eye pressure dangerously.
- Certain anaesthetic procedures — inform any medical or dental professional that you have a gas bubble in your eye before undergoing any procedure involving general anaesthesia.
- Strenuous physical activity should be avoided during the early recovery period to support healing.
Light activities can generally be resumed within a few days of surgery. However, tasks requiring sustained visual attention — such as driving, reading, and screen-based work — may be affected until vision stabilises and the gas bubble has fully dissolved.
Regular post-operative consultations and OCT scans are an essential part of recovery. These allow your specialist to monitor the healing process, confirm macular hole closure, and detect any complications early.
Surgical outcomes are influenced by the size of the macular hole and the duration of symptoms prior to treatment. Early intervention offers the best chance of successful closure and meaningful visual recovery.
Frequently Asked Questions About Macular Hole Surgery
No. The procedure is performed under local or general anaesthesia, ensuring patient comfort throughout. Most patients experience only mild pressure or a sensation of movement during surgery, but not pain. Any post-operative discomfort is generally mild and well managed with prescribed pain relief.
Most patients are able to resume light activities within a few days of surgery. However, full visual recovery — including the resolution of distortion and improvement in central clarity — can take several weeks to months, depending on the size and duration of the macular hole prior to surgery.
Many macular holes close successfully following vitrectomy, particularly when surgery is performed early. Smaller, recently formed holes generally have higher closure rates and better visual outcomes. Larger or long-standing holes can still be treated but may have a lower rate of complete closure and less predictable visual recovery.
No. Neither glasses nor medication can repair a macular hole. Vitrectomy surgery is currently the only proven and effective treatment for closing a full-thickness macular hole and restoring central vision.
