Retina is a thin layer of light sensitive tissue on the back wall of the eye. These light sensitive tissues convert the incoming light into signal that is carried to the brain via. the optic nerve. Retinal detachment is a condition where this thin layer of light sensitive tissue peels away from the underlying layer of support tissue. Retinal detachment may be caused due to an injury or trauma to the eye or head or may be due to preexisting factors like myopia (short-sightedness) and prior ocular surgery.
Early diagnosis and corrective surgery is important to repair the retinal detachment.
Sutureless Vitrectomy 25 gauge:
Vitrectomy is a procedure that involves removal of vitreous gel from the eye. It is a clear gel like substance behind the lens of the eye. Suture-less Vitrectomy procedure makes use of special equipment (a 25gauge cutter) that enables the surgeon to remove the vitreous gel by making small cuts which are as small as 0.5mm. The main advantage is that the cuts close automatically and do not require any sutures, thus reducing healing time. The patients can resume their daily work at the earliest.
At Elite Eye Hospital, our experienced surgeons prefer to perform Suture-less Vitrectomy because of the faster recovery of patient, lesser operative time and increasing the comfort of the patient in the post-operative period. Symptoms:
i)Blinking lights and floaters[spots or thread like images appearing on the eye] are initial symptoms of retinal detachment.
ii)A slight heavy feeling in the eye.
iii)If the patient has a impression of a shadow or a curtain affecting the visual sense, can indicate that a retinal tear has progressed to detached retina.
Diabetes also may cause retinal detachment. Because of abnormal blood vessels and capillaries, blood might bleed into the vitreous gel causing damage to the retina, eventually leading to the retina peeling away.
Retinal detachment is usually seen in younger adults to middle aged individuals [25 years to 50 years], and also in older individuals following a cataract surgery.
Retinal Detachment Surgery:
Surgery is the only treatment for retinal detachment. Elite Eye Hospital has the latest technology and experienced ophthalmologists performing “Retinal Detachment Surgery”.
Prior to the operation patient will be asked not to consume or drink anything six hours prior to operation. The surgical procedure is performed under local anesthesia and eye drops are added during the operation to widen the pupil.
Post surgery patient can leave the same day or will have to remain in hospital for one day depending on the condition.
Three kinds of surgery are performed for Retinal Detachment.
i) Vitrectomy (25gauge) :
Vitrectomy is popularly used for treatment of retinal detachment. In vitrectomy, first the vitreous gel of the eye is removed and replaced with a gas to refill the eye and to reposition the retina. Once the gas gets absorbed (within few weeks), it is again replaced by the eyes own natural fluid.
ii) Pneumatic Retinopexy :
Pneumatic Retinopexy is another surgery to correct retinal detachment cases. Performed under local anesthesia, the surgeon injects a gas bubble directly into the vitreous cavity. The gas bubble pushes the detached retina back to the outer wall of the eye thereby attaching to the wall.
Later a laser or cryotherapy is used to seal the hole or tear.
iii) Scleral Buckling:
In sclera buckling a surgeon sews a band which is either made up of silicone, sponge, or plastic over the outer wall of the eye. The band compresses the eye so that the hole or tear in the retina is pushed against the outer sclera wall of the eye thereby closing the break or reducing fluid flow and in turn allowing the retina to re-attach.
