CENTRAL VISION LOSS
The affectation of the retina’s central area, the macula, can cause a diminishment of visual acuity and/or a partial or total loss of central vision. According to the patient’s age and the eye’s characteristics, we can describe various causes.
AGE-RELATED MACULAR DEGENERATION (AMD)
These are the most frequent three pathologies that produce central vision diminishment but they aren’t the only ones. We advise you to go to the ophthalmologist’s as quickly as possible should this symptom appear, so that he examines your fundus and, if necessary, performs further complementary tests.
CENTRAL SEROUS CHORIORETINOPATHY
This is, without any doubt, the most common cause of central vision loss. This is a degenerative disease of the macula that leads to a deterioration of the retinal cells as well as the retinal pigment epithelium. There exist two clinical forms of macular degeneration: the atrophic one and the exudative one. Nowadays, the atrophic form lacks of an effective treatment and we can only advise keeping a healthy lifestyle. Following a correct Mediterranean diet as well as giving up smoking may help to slow down the development of this disease. The exudative form is currently treated by means of intravitreal antiangiogenic injections obtaining very good results.
Retinal discontinuity at macular level is known as macular hole. This pathology, which can be due to several causes, leads to a truly reduction of visual acuity. Once a macular hole has appeared, it must be treated by means of surgery.
This is a disease that normally affects middle-aged men and it usually originates a central vision diminishment. It isn’t such a severe reduction as in AMD, but since it affects working age people it can be really disabling. The most important risk factor to suffer from this problem is stress in first place, followed by the ingestion of corticosteroids. We, therefore, advise reducing stress and avoiding, at all costs, the use of steroids. As months go by the problem generally decreases and most patients don’t need any treatment at all. In case CSC persisted over time, a kind of laser, photodynamic therapy, could be applied to try to solve it.
