![]() In diabetes, the high sugar content of the blood causes structural changes to occur in the retina. ![]() Tractional detachments are commonly seen in diabetes but can occur in other retinal diseases that are characterized by loss of the normal blood supply to the retina over time. Once the macula is detached and central vision affected, the prognosis for recovery of central vision is more guarded, though patients often can regain good visual acuity over time. Patients in whom the macula is not involved with the detachment at the time of diagnosis, usually have preserved central vision and have a better prognosis for good vision postoperatively. Your retina specialist will examine you and tailor an individualized surgical plan.Īn important factor in the visual prognosis of patients with a rhegmatogenous retinal detachment is the involvement of the macula, the center of the retina. Some detached retinas necessitate the combination of a scleral buckle and vitrectomy. Scleral buckles can be used to repair retinal detachments with or without drainage of the subretinal fluid. The retinal tears are usually sealed with cryopexy (freezing) that is done from outside the wall of the eye. The retinal tears are supported on the scleral buckle, thus sealing them to the wall of the eye and repairing the detachment. It is placed behind the eyelids, and under the conjunctiva and tenon capsule (clear/white external “skin” layer of the eye) and, therefore, is not seen. A scleral buckle is a thin silicone band that is placed around the eye, like a belt, and supports the retina from the outside. The goal is for the retina to stay reattached once the gas bubble goes away or once the oil bubble is removed.Īnother procedure for the repair of retinal detachment is a scleral buckle. An oil bubble is usually left in the eye for 3-6 months, but sometimes longer or shorter, and needs a separate procedure to remove the oil in the future. A gas bubble lasts about a month and goes away on its own. This bubble serves to push the retina back into the correct position. Finally, an inert gas bubble or silicone oil bubble are used to fill the vitreous cavity in the eye. ![]() The laser is then used to seal the retinal tears. Vitrectomy is where most of the vitreous gel is removed, and the retina flattened from the inside of the eye. Surgical correction of a detached retina includes vitrectomy surgery. This seals the break to the wall of the eye and is the key step in repairing a retinal detachment. Pneumatic retinopexy is an in-office procedure in which gas is injected into the vitreous cavity to re-attach the retina and cryopexy (freezing), or laser, is used to demarcate or weld around the retinal break. There are several ways in which retinal detachments can be repaired, depending on many factors such as the age of the patient, the location, distribution and number of retinal breaks, among others. The portion of the retina that is detached does not have normal vision and is often described by patients as “a veil, curtain or shadow coming over the vision”. Once a tear is formed, fluid can get underneath the retina, and cause it to detach. Holes or tears, in turn, can happen because of pulling by the liquifying vitreous gel (a normal aging change) or can be traumatic. Rhegmatogenous detached retinas are the most common detachments and happen because of a hole or tear in the retina, usually in the peripheral retina. What is a rhegmatogenous retinal detachment? Exudative retinal detachment (Serous retinal detachment).Rhegmatogenous retinal detachment (most common, accounting for 90% of all detachments).Retinal detachment is an emergency condition where the neuro-sensory tissue in the back of the eye (retina) separates from its blood supply. If you call us after hours, please press 2 and leave an urgent message for the on-call doctor and we will get back to you right away. You may call our office 24/7 and we can help you. If you are experiencing any of the below signs and symptoms, please find immediate medical attention. The longer it goes untreated the greater the risk of permanent vision loss in the affected eye. Retinal Detachment is a medical emergency that could cause permanent blindness.
