It could very frightening if sight in any of the eyes abruptly becomes blurry and unclear, as can occur with growth of macular hole.
To know how macular holes develop, it is essential to know first something regarding eye anatomy.
The macula is a very tiny spot at the middle portion in the backside in the eye (retina) wherein holes develop.
The macula is also full of light-sensitive cells known as cones.
The whole rest of retina is composed of photosensitive unit called rods which see white and black shading, movements and shapes (like for night sights and side visions).
Since macular holes are frequently related with aging processes, they develop more likely if the person reaches the age of over 60 years.
Women have a little higher risk of this eye disease compared to men.
When the disease develop, most individuals observe sudden reduction of vision in any eye.
Macular holes, cysts and tears are not similar as another eye-disease related to age which is called macular degeneration, that may happen also more often to those who are over 60.
There are various reasons why macular holes happen: The backside of the eye if full of thick, gel-like substance called vitreous humor ( it is called vitreous in short) which helps the eye maintain its form.
The lucid vitreous reduces in size and becomes more fluid due to aging, causing it to spill around.
Because of the attachment of the vitreous to retina along with small strands of unit of cell, it may pull the retina up while it shrinks.
Occasionally, this shrinkage may essentially destroy a portion out the retina, which will cause the hole.
When this missing section of retina be within the macula, then it is called macular hole.
Another reason why there is this ailment because of shrinkage of vitreous happens when the threads stay connected with the retina and shatter away from vitreous.
These threads may contract just about the macula and may cause the hole due to traction.
In either situation, fluid develops wherein the vitreous contract to fill up the spaces.
This liquid can escape into macular hole which causes the blurring and distorted sight.
Macular hole may worsen any time when left untreated.
This eye ailment sometimes can be resolved without intervention but should be treated mostly to avoid permanent loss of vision.
Vitrectomy is the treatment most commonly done to cure macular holes.
In this surgical procedure, the vitreous is removed by the retinal specialist to prevent it in pulling the retina.
After removal of the vitreous, the specialist inserts the mixture of gas and air in the space once the vitreous occupied it.
The bubbles of gas and air put the force on the ends of the holes of the macula then allow it to heal.
As the bubble does its task, the patient must recline face down in order for the bubble to stay in exact place within the eye, sometimes it may take two to three weeks.
This medication is totally necessary in order to attain the best sight after treatment.
The gas/air bubble slowly leaves away as time goes and normal eye liquids take the place while the healing of the hole is going on.
Risks of vitreous operation include retinal detachment and infection which are treatable.
The most ordinary risk is cataract development.
Cataract generally happens rather rapidly after vitrectomy, but it can be detached once the eyes had healed.
