Retinal Detachment Surgery – all you should know
Eyes are complex structures which can`t be explained with simple words. However, the retina is a part of the eye structure so it is important. We decided to explain a little bit more for retinal detachment surgery. It is attached to some underlying tissue in the centre of the eye. Retinal detachment is a retinal disease which damages the human vision. Reasons are hiding in high levels of myopia or some other eye disease, as Asiaretina informs us – retinal detachment might occur because of some health conditions which are not directly connected to the vision. It is good to know that retinal detachment might not be a complete detachment but a hole or break. Both of them are still dangerous conditions and patients should visit an ophthalmologist as soon as possible. First, the patient starts to see flashing lights, which don`t exist. Human eyes might see these reflections when something is wrong with the vision. Having an examination fast is important because the treatment reaches better results when the retina is not fully detached.
Symptoms for retinal detachment
As we already mentioned, the patient will see some flashing lights. The eye specialist will insist to apply some eye drops to the patient and to dilate the pupils. This is the only possible way to examine the eyes properly. A possible reason for flashing lights might be PVD, which is posterior vitreous detachment. It is slightly different from retinal detachment. A serious symptom is a curtain – it might be a sign the patient doesn`t have just a tear but detached retina. If this happens the eye doctor has to perform surgery before the central area of the macular detaches. At first stages the patient loses his side vision, in the end, he might lose his vision completely.
Retinal detachment surgery, reports AsiaRetina, is a complex surgery but it is often successful. However, the disadvantage is that patients need more than 1 treatment. Most people think that their vision will not be like before but this is not true every single time. Some people recover completely while others lose their ability to read, for example. This is due to a lot of time spent with the detached retina or some scar tissue has occurred after the surgery. Unfortunately, scar tissue is an eye problem, also.
If you suspect that you have retinal tear better find an ophthalmologist as soon as possible. All of them will be able to diagnose it but the only vitreoretinal surgeon will make your surgery. Vitreoretinal surgeons are actually ophthalmologists who have additional education in vitrectomy.
What is vitrectomy?
It is the most popular surgery for retinal tears and detachment. The surgery might be provided under local or general anaesthesia – the surgeon removes the vitreous gel of the eye so the procedure can`t go without any type of anaesthesia. If there is a tear or a hole, the vitreoretinal surgeon uses a laser to close it but before that he full the empty space of vitreous gel with gas. Don`t worry the gas doesn`t stay in the patient`s eye for too long – it is replaced naturally by eye fluids. However, the first few days and even weeks patients have to sleep with their head positioned downwards.
Sometimes in addition to vitrectomy, for more complicated cases, surgeons use scleral buckling. It is a way of sealing the tear and later using the scar tissue to recover the eye. A scleral buckle is positioned on the back of the eye to hold the structure tight. The scleral buckle is made of silicone or plastic.
What should patients expect after the surgery?
Unfortunately, this surgery is not one of the most comfortable. Eye drops are prescribed because the eye is itching, watering and swelling. If the surgery was with scleral buckle then the patient needs new eyeglasses. The reason is hiding in the fact the scleral buckle tight the eye and changes its form. In addition, some patients have blurred vision months after the surgery. Side effects are double vision, glaucoma, cataract and even drooping eyelid. The last one is possible because the surgeon might reach levator muscle, which holds the eyelid.
Although the surgery has lots of side effects and thing that most people don`t want to experience while recovering, it is a better decision to have the surgery on time, instead of losing your vision completely.
