WHAT IS RETINITIS PIGMENTOSA?
Retinitis pigmentosa is a disease which belongs to a group of disorders whose cause is a disorder of genetic, with slow progressive loss of vision. The retina is the layer that lines the eye, where it generates the electrical impulse that sends images to the brain. In retinitis pigmentosa occurs gradual destruction of some cells of the retina and the formation of pigment clumping.
WHAT ARE THE SYMPTOMS OF RETINITIS PIGMENTOSA?
The first symptoms usually appear during youth, but can be seen at any age. Reduced night vision "night blindness", or in areas with low light is the most common symptom of retinitis pigmentosa. People with normal vision adjust to darkness after a brief period of time and are able to distinguish shapes and objects. People with night blindness are very slow to adapt, slow to see when moving from one environment to another with dark light, as when we entered a tunnel driving or when entering a cinema. The peripheral visual field loss is a serious impediment to these people, because the patient's mobility is more complicated.
WHY IS IT IMPORTANT TO KNOW HEREDITY IN RETINITIS PIGMENTOSA?
Most forms of retinitis pigmentosa are inherited. Different inheritance patterns are associated with different degrees of progression and if we try to learn more about the family, this may help us predict how it will continue that patient. This knowledge is also helpful in some decisions when to have children ("genetic counseling) or deciding studies or profession.
IS THERE A TREATMENT FOR RETINITIS PIGMENTOSA?
In general there is no specific treatment, although some forms can benefit from a booster therapy with vitamins, minerals or other principles. Most research is aimed at solving the problem of loss of vision and visual field. Until a fully effective treatment, it is important for patients with this condition do not be fooled by those who claim a "secret cure" or a "miracle drug".
Patients with retinitis pigmentosa may develop other conditions, such as glaucoma or cataracts, both treatable. Low vision aids can be a great help to these patients. The main benefit I have to improve contrast and glare.
Although visual loss, patients with retinitis pigmentosa can make your life adapting to the situation through some rehabilitation services today are now available. Visual Therapy aimed at improving contrast sensitivity has been very effective in these patients, requires some exercises monitored by the ophthalmologist, the patient can perform at home and involving a significant improvement in visual conditions.
WHY ARE IMPORTANT FRECUENT VISUAL CONTROLS?
Eye disease can occur at any age. Some changes do not cause symptoms until the disease has caused irreversible damage. Regular eye exams are important because most of blindness are preventable if a diagnosis and early treatment.
