Retina is the front part of an eye which is responsible for eye-sight. This central part of eye is covered with a special type of nerve cells that are very close together in the middle of the retina, called macula. At times, these nerve cells separate from each other and pull away from eye surface, causing a macular-hole.
If the hole is too small and does not cause major vision problems, the doctors do not suggest mocualr surgery in Melbourne. They would suggest patients to go for frequent eye check-ups to ensure that hole does not increase in size and don’t cause any other vision problems.
In cases when a patient faces severe problems and the hole is significant, a specialist would suggest a surgery. Before treating the hole, the ophthalmologist performs vitrectomy procedure on the effected eye. During this procedure, the surgeon makes a cut in the outer layer of the eye. A needle is inserted through the cut to remove the vitreous fluid. The cut is also used for removing scar tissues. Once the liquid is removed, the surgeon proceeds with macular-hole treatment.
The specialists now remove membranes or tissue pieces that are left using fine forceps. Such debris is removed to prevent anything from closing the macula hole. Once they are sure that there are no membranes left, the hole is filled with a sterile gas in place vitreous fluid. The gas is inserted to keep enough pressure on macula until it heals. Patients are advised to maintain face-down position for a week at least, to keep the gas in place and faster macula healing.
In most cases, the surgery is successful, but patients may face problem with their vision if they do not maintain face-down position. Normally after a successful surgery, the patients may not face any significant problem with sight, but in few cases the amount of regained vision varies.
If patients observe few symptoms like appearance of dark spots, difficulty in seeing fine details, it is better to approach a specialist, who could conduct few tests and suggest the best possible treatment.
