A macular hole
refers to a hole affecting the central part of the retina
- called macula. It is commonly seen in the over 60’s
population and tends to be more common in women than men.
It presents with a gradual drop in vision usually associated
with distortion (straight lines appear “wiggly”).
With time, the macular hole becomes larger, causing further
deterioration in vision.
The diagnosis is made by your eye surgeon after a retinal
examination through dilated pupils.

Vitrectomy Surgery for Macular Holes
The only current treatment for macular holes is surgery called
vitrectomy, where the “gelly” (vitreous) inside
the eye and the very superficial layer of the retina (Internal
Limiting Membrane – ILM) are removed. A bubble of gas
is placed inside the eye that acts as a splint to close the
macular hole. The vision will be very blurred after the surgery
because of the gas inside the eye. This gas is gradually absorbed
by the eye, and when it disappears the vision usually improves.
Eye drops are required for a few weeks after the surgery the
reduce the inflammation in the eye. There is a 90-95% chance
of closure of the hole with this type of operation, and the
improvement in vision will depend on how long the hole has
been present.
