This is quite normal as the retina is still functioning. Sometime small dissolvable stitches are used to seal incisions made in the white of the eye, although in many cases, no sutures are required.ĭuring the operation you may be aware of pressure sensations around the eye, or some shadows and lights inside the eye. At the same time, we also use either laser treatment inside the eye, or freezing treatment (cryotherapy) from outside the eye, to help seal the retinal holes. This choice is made depending upon how the eye and retina behave during the procedure. This is either a gas bubble or silicone oil, which supports the retina whilst healing takes place. After removal of the vitreous, the retina is repositioned using an internal splint. As this is happening, the vitreous is replaced by a salty fluid. An operation called a Vitrectomy is performed, involving making three microscopic openings in the white of the eye, so that tiny instruments can be used to cut away the vitreous gel from inside the eye. You will also be advised that the plan may change during the operation, depending on how the eye and retina behaves during the operation. Your surgeon will advise you which approach is best for your particular case before the operation. There are two approaches to retinal detachment surgery, these are described below. You will be asleep for the operation, which takes approximately one hour. The anaesthetist will come and visit you on the ward before the operation takes place. In some circumstances you may need a general anaesthetic in this case you will be asked not to eat or drink for several hours before the operation. You will need to keep your head still for the duration of the operation. You will have an injection of local anaesthetic into the tissues around the eye, which numbs your eye. You will be aware of bright lights and you may experience some slight discomfort. You will be awake for the whole operation. We normally carry out the operation under local anaesthetic. The operation is aimed at sealing the retinal holes and reattaching the retina to the inside of the eye. Your surgeon will advise you on the chances of success with the operation. It is important that you realise that some patients need more than one operation to treat their retinal detachment. Every patient is different and retinal detachments vary in their complexity. You need to be aware that surgery for retinal detachment is not always successful. Successful surgery will usually bring back some of your sight, however it will not usually completely restore your vision. You will have already lost some of your sight as a result of the retinal detachment. Yes, as the most obvious benefit is the prevention of blindness and restoration of vision. Further information is also available in the booklet ‘Retinal Detachment’ published by the Royal National Institute for the Blind RNIB. It is known that some people are at a greater risk of developing retinal detachments for instance people who are short sighted, those who have had cataract surgery and those who have had a severe blow directly to the eye. Without treatment this usually leads to permanent loss of vision in the affected eye.Ī retinal detachment can occur at any time with no apparent cause. The result of this process is the loss of whole or part of your vision. Retinal detachments occur when a hole or several holes have developed in the retina, fluid has passed through the holes causing the retina to peel away from the inside of the eye similar to a blister. It is sensitive to light like the film in a camera and is essential for you to be able to see. The retina is a thin layer of nerve cells and blood vessels that lines the inside of the eye.
