July 16, 2012 The retina is the inner layer of the eye that receives light stimuli (such as film in the camera). Retina is normally attached to the choroid. Although the retina has its own circulatory system, metabolic needs of the retina are much higher and it takes them further from the choroid.
Short-sighted people have a particularly increased risk for retinal ablation because of the “thinner” eye membrane and frequent peripheral retinal degenerations.
Causes:
Ablation of the retina usually occurs as a result of retinal break (rupture) on the periphery, which we can determine by the examination of the eye background. Some other diseases such as proliferative diabetic retinopathy can lead to the emergence of ablation of the retina.
Symptoms:
Rupture of the retina in the early stage is usually accompanied by symptoms such as flashing, the appearance of smoke, cobwebs, curtains, flies, etc. before the eye. In the later stages occur narrowing of the visual field and decrease of visual acuity.
Treatment:
If the condition of ablation persists longer it leads to a gradual deterioration of the retina which makes it difficult to recover after surgery.
It is very important to detect rupture of the retina at an early stage because then the possibility of successful treatment is much higher. If the rupture is detected before the formation of ablation, Argon laser photocoagulation can be done around the rupture. This process can in most cases successfully prevent the occurrence of retinal ablation and a series of further complications.
Retinal ablation is a serious condition that requires urgent surgical treatment.
