INTRODUCTION
The retina lines the inside of the eye and is a thin tissue composed of layers of light-sensitive cells which send visual information to the brain. The retina is held in place by the vitreous humor which is a transparent gel composed of water and collagen and lies in the centre of the globe of the eye between the retina and lens. A retinal detachment occurs when the retina pulls away from inside wall of the eye causing loss of vision. This is often due to a hole or tear in the retina produced when the vitreous liquifies with the aging process. Trauma may also lead to retinal detachment. The vitreous may also become filled with blood, particularly in association with severe diabetic eye disease where traction may detach localized areas of retina.
THE OPERATION
The indications for retinal surgery include:
Small holes or tears in the retina may be treated with laser photocoagulation or cryopexy (freezing). Laser photocoagulation consists of pinpoints of laser which creates minute burns around a small hole in order to help the retina adhere to the wall of the eye. It can also be used to treat areas of the retina which have a poor blood supply.
Cryopexy: is a procedure which freezes the area around a hole to the wall of the eye.
Scleral buckling: is a surgical procedure used in large retinal detachments in which a synthetic band is placed around the outside of the eye in order to push the wall of the eye against the detached retina.
Vitrectomy: is the surgical removal of diseased vitreous and the insertion of an artificial substance to push the retina back against the wall of the eye. The substance may consist of an expandable gas or silicone oil. The gas is slowly absorbed by the body after a couple of weeks. The silicone oil may be removed surgically when Dr Pratik decides it is necessary.
THE RISKS OF SURGERY
1. Reaction to an aesthetic agent
2. Infection
3. Bleeding
4. Cataract
5. Secondary Glaucoma
6.Failure to attain the intended outcome
7. Blindness
8. Need of repeat surgeries
SPECIFIC PRE-OPERATIVE PREPARATION
You will not need to compulsory be nil-by-mouth before the operation. Most of time Dr Pratik prefers under local anesthesia with mild sedation given by a senior anesthetist. A light breakfast can be taken in the morning if no specific instructions have been given. You should have a shower, shave and wash your hair before the operation. You will be prescribed frequent antibiotic eye drops before surgery.
LENGTH OF TIME IN HOSPITAL
From morning till evening.
AFTER THE OPERATION
DISCHARGE INFORMATION
ADDITIONAL INFORMATION
Do not fly in an aeroplane after retinal surgery if you have a gas bubble in your eye, because the changing air pressures in the plane will affect the gas bubble in your eye. The air pressures can also change if you drive up into the hills.
FOLLOW UP
It is important that you keep your outpatient’s appointment. If you need to change the time or date please call 0777 108 9999 If you develop excessive pain, swelling, bleeding, offensive odour or discharge from your eye, or decrease in your vision, contact 0777 108 9999.
