Macular Hole
Macular Hole is not uncommon over age 50 years. It is common in males and females but more common in females. It presents either with sudden central distortion or as an incidental finding at an optician visit.
​
The most common cause is interaction of the vitreous face with the macular surface. As we get older, the vitreous separates from the retinal surface and usually does so without any pulling on the retina or macula. In some persons, the vitreous gel pulls on the fovea which results in a macular hole.
​
Macular holes can be seen as being in stages depending on how much separation has occurred from the vitreous. Earlier stage 1 macular holes have a high chance of closing spontaenously so these should be observed at first. If they progress to stage 3, surgery is recommended within 3 months of onset of the macular hole to give the best visual outcome.
​
Surgery for macular holes is very successful (95%) and results in visual improvement at least 70% of the time. During surgery, vitrectomy is performed. The membrane around the macular hole (ILM) is peeled and a gas bubble is placed in the vitreous cavity.
​
After surgery the patient may need to lie face down for 5-7 days to get the best closure of the macular hole.
VITRECTOMY
Vitrectomy is done to remove the vitreous gel for floaters, bleeding, macular hole, macular membrane and retinal detachment.
