The detachment of the retina is a disorder of one of the tunics that are important for the composition of the image, we have it in what we call the fundus, and the problem of retinal detachment is that that tunic dislodges from its site, It stops being where it should be and therefore can not perform its function. It is usually preceded by a break or some acquired alteration of the retina.
Symptoms of retinal detachment
The detachment of the retina, fundamentally, appears as a loss of vision that can be variable depending on which area of the retina is the one that suffers. If it is the central area we have a loss of the important visual acuity, and if what we begin to notice are losses of the peripheral visual field, we have to look for the retinal detachment in the most external, more extreme areas of the retina.
Causes of retinal detachment
The causes are multiple. Normally, those that have some kind of alteration, either congenital or structural, and that due to the degradation of the vitreous humor, the relation of the vitreous humor with the retina, produce tractions, ruptures or holes, and a series of factors that lead to the liquid, to liquefied vitreous humor leaking through these holes, for these breaks, and the retina is dissected and let go. Then there are other causes, a little more external, such as traumatic ones, or they may even be tumors, inflammatory diseases, but they are usually preceded by a type of structural alteration of the retina.
Treatment of retinal detachment
The treatment of detachment of the retina is mainly surgical, although in very early cases we can use laser techniques to block these holes, or these small alterations. Normally we have to resort to surgeries that can be variable depending on where they have been broken and what is the extent of the retinal detachment. Techniques without entering the eye, which we call extrascleral, or even putting inside the eye that are the intraectomies that we have to work, apply the technique from within and generate the appropriate scars so that they do not happen again.
