The first signs of detachment
This type of retinal injury is more common in near-sighted people. The cause for this is likely an elongated shape of the eye. The first sign of retinal detachment can be sudden flashes of light or floaters. In its progressive stage, a shadow, or curtain, appears over a portion of the visual field. It is then possible that the patient suffers a complete loss of vision.
Regular examinations of the eye fundus
The main method of preventing severe vison impairment due to retinal detachment is to have regular examinations of the eye fundus. These check-ups should be taken by all individuals who have wide pupils and are therefore at highest risk of retinal detachment. These are primarily patients with high degrees of nearsightedness. It is important to monitor retinal changes with periodic OCT examinations and, if required, with laser sealing of these changes, which can prevent the development of retinal detachment. If retinal detachment should occur, the only effective treatment is surgery that must be performed as soon as possible.
Glaucoma is an eye disease that is indicated by increased intraocular pressure. This gradually leads to optic nerve damage that is first noticeable by a worsening of peripheral vision and can later lead to more severe visual impairment and, in worst cases, complete blindness.
Macular degeneration is a disease progression that affects the area of the macula on the retina. This area has the greatest number of vision receptors and is also the area of sharpest visual acuity. Macular degeneration usually occurs in older adults. Many factors influence on the development and progression of this disease, including high blood pressure and poor circulation within the macula.
In diabetic retinopathy, there occur changes in the eye fundus that are a consequence of excessively high levels of blood glucose levels in diabetic patients. High levels of glucose cause tiny blood vessels in the eye fundus to start swelling and then to leak fluid. Minor bleeding can occur at the site of the damaged vessels. In its early stages, this bleeding is not perceptible and causes no trouble to patients.
