What is a Macular Hole?
A macular hole is a small break in the macula, located in the
center of the eye's light-sensitive tissue called the retina.
The eye contains a jelly-like substance called the vitreous.
Shrinking of the vitreous usually causes the hole. As a person
ages, the vitreous becomes watery and begins to pull away from
the retina. If the vitreous is firmly attached to the retina when
it pulls away, a hole can result. This may also occur after an injury
to the eye.
Blurred and distorted central vision of the affected eye are the most
common symptoms of a macular hole. Mostly these symptoms appear
It is important to visit an ophthalmologist as soon as possible whenever these symptomes occur as early treatment improves the visual outcome.
Visual testing and examination of the retina by fundoscopy after dilation of the pupils are standard methods of diagnosing a macular hole. Nowadays an OCT (ophthalmic coherence tomography) is usually performed to better assess the prognosis for surgery and also to check the other eye.
Macular Hole Treatment
A vitrectomy is usually performed to repair a macular hole. Usually a gas bubble is injected into the eye at the end of the surgery, with face-down positioning for several days to 1 week prescribed to facilitate the closure of the macular hole.
If treated early the closure rate is close to 95% of all cases.
People who have a macular hole in 1 eye have a slightly higher risk of developing it in the other eye. OCT follow-up is usually recommended on a periodic basis.
