Macula Hole Surgery in Singapore
MACULA HOLE SURGERY
What is a Macula Hole?
The macula is the central part of the retina responsible for sharp, detailed vision, the vision you use for reading, recognising faces, and driving.
A macula hole is a small break that forms in this central area, disrupting the normal layered structure of the retina and causing distortion or loss of central vision.
Most macula holes are idiopathic, meaning they occur without an identifiable underlying disease, and are related to age-related changes in the vitreous gel. As the vitreous separates from the retina with age (posterior vitreous detachment), it can sometimes remain abnormally attached to the macula, exerting traction that gradually pulls the central retina apart and forms a hole.
Macula holes are distinct from an epiretinal membrane (macula pucker), where a membrane forms on the surface of the retina causing wrinkling rather than a break in the tissue, though the two conditions can occasionally occur together. For more on this, see our Macula Pucker / Epiretinal Membrane page.
Symptoms of a Macula Hole
Because a macula hole affects the central retina directly, symptoms are usually noticed early and tend to involve central, rather than peripheral, vision:
​
-
Blurred or distorted central vision, often noticed first when reading or looking at straight lines
-
Wavy or warped lines, particularly noticeable with straight edges such as door frames, window blinds, or text
-
A grey, dark, or missing spot in the centre of vision (a central scotoma).
-
Difficulty with detailed tasks such as reading, threading a needle, or recognising faces.
-
Symptoms are typically limited to one eye initially, though the other eye should also be monitored
Peripheral (side) vision is generally unaffected, as a macula hole does not involve the rest of the retina.
What Causes a Macula Hole?
-
Age-related vitreous changes (most common): abnormal vitreomacular traction during posterior vitreous detachment is the leading cause, most often affecting people over 60
-
Eye trauma: a blow to the eye can cause a traumatic macula hole, which may occur in younger patients.
-
High myopia: associated with a higher risk of macular structural changes, including macula holes.
-
Other retinal conditions: macula holes can occasionally develop in association with other conditions affecting the vitreomacular interface
Stages and Severity
Macula holes are often described by their size and stage, which influences both the likelihood of spontaneous closure and the surgical approach:
​
-
Small or early-stage holes: some very early changes (sometimes called impending or stage 1 holes) can occasionally resolve without surgery if the vitreous traction releases on its own
​
-
Full-thickness holes: once a hole extends through the full thickness of the retina, it does not close on its own and requires surgical treatment to restore the retinal anatomy.
The size of the hole, measured during OCT imaging, is an important factor in planning surgery and in counselling patients on the likely visual outcome.
Why EarlyAssessment Matters
The duration and size of a macula hole are both associated with the likelihood of successful anatomical closure and the degree of visual recovery after surgery.
Holes that have been present for a shorter time and are smaller in size are generally associated with better outcomes, while larger or longer-standing holes may still be treated successfully but with a more gradual or limited visual recovery.
This is why prompt assessment by a retina specialist is recommended once symptoms such as central distortion or wavy lines are noticed.
How is a Macula Hole Diagnosed?
Diagnosis is made through a clinical examination combined with optical coherence tomography (OCT), a non-invasive imaging scan that produces a detailed cross-sectional image of the macula. OCT allows the size, stage, and configuration of the hole to be precisely measured, which is essential for surgical planning and for monitoring the fellow eye over time.
Macula Hole Surgical Repair
The standard treatment for a full-thickness macula hole is vitrectomy surgery, which typically involves the following steps:
Vitrectomy: the vitreous gel is removed from the eye to relieve traction on the macula.
Staining and ILM peeling: a special dye (such as a blue stain) is used to enhance visualisation of the internal limiting membrane (ILM), a thin layer on the surface of the retina. This membrane is carefully peeled away from around the hole to release residual traction and encourage the edges of the hole to come together.
Gas tamponade: a gas bubble is injected into the eye at the end of surgery. This bubble presses gently against the macula, helping to hold the edges of the hole together while it heals and seals.
For larger or more chronic holes, additional techniques may be used, such as an inverted ILM flap, where a small flap of the peeled membrane is folded over the hole to act as a scaffold for closure. In select, more complex or refractory cases, other specialised techniques, including autologous retinal grafting, may be considered. These approaches are discussed individually where relevant, based on the specific characteristics of the hole.
RecoveryAfter Macula Hole Surgery
-
Most patients return home on the same day as surgery.
-
Because a gas bubble is used to support the macula, patients are typically advised to maintain a face-down or head-tilted position for a period after surgery, the exact duration depends on the gas used and the surgeon's assessment.
-
Vision is often blurred immediately after surgery due to the gas bubble, and gradually clears as the gas is absorbed over several weeks.
-
While the gas bubble is present, air travel must be avoided, as changes in air pressure can cause the bubble to expand and raise eye pressure dangerously.
-
Visual improvement continues gradually over weeks to months as the retina heals, and central distortion often improves significantly, though it may not always resolve completely.
-
Regular follow-up visits, including OCT imaging, are used to confirm that the hole has closed and to monitor healing
