Dr Mateo uses a new technique in cases of retina detachment

A silicone belt encircles the eyeball to enable the retina to be reattached in cases of detachment or splitting. Dr Mateo is one of the few specialist in Europe to use this new technique.

Dr Carlos Mateo, a retina specialist at the IMO, is one of the few specialists in the world to use macular indentation, a technique associated with vitrectomy surgery, for cases of retinal detachment caused by a macular hole (lack of tissue in the central part of the retina) or retinoschisis (progressive splitting of the retina’s layers) in patients with high myopia.

Macular indentation consists of placing a piece of silicone containing threads of titanium at the side and back of the eyeball to change its curvature and hold it in a new stable position, in order for the retina (the thin layer that lines the inside wall of the eyeball), which has been detached due to the elongation of the eyeball, can return to its correct position. The technique is used in patients with retinal problems caused by high myopia, in which the eyeball is longer than normal, causing excessive stretching of the retina, resulting in its detachment or splitting into layers, thus directly affecting the vision of patients.

Dr Carlos Mateo has treated more than 70 patients with this technique, with excellent results. "The piece of silicone, when placed in position, presses the back of the eyeball, reducing the excessive elongation of its wall," he explains. By doing so, the piece acts like a belt that gives the eyeball a more suitable length for the retina to remain attached to its inner wall and avoid detachment or degeneration of the layers of the retina due to separation, which can recur in abnormally elongated eyes.

In many cases, indentation is an alternative to silicone oil, a fluid that is inserted into the eyeball after some vitrectomy procedures to keep the retina attached to the wall of the eyeball. According to IMO specialist, indentation produces much better results, since it is a definitive technique in which, in most cases, long-term problems associated with silicone oil, such as glaucoma or progressive atrophy of the optic nerve, are avoided.
