Retina dystrophy
Contents:
Description:
Dystrophies of a retina are the reason of decrease and loss of sight. Distinguish hereditary tapetoretinalny (abiotrophy) and involutional (sclerous) dystrophies.
Retina Dystrophy symptoms:
Pigmental retinitis - - the basic hereditary disease of a retina which is found at 0,5% of the "unselected" population. The progressing bilateral disease which is shown a night blindness (hemeralopia), narrowing of a field of vision, an atrophy of an optic nerve.
At an oftalmoskopiya it is possible to find three main symptoms: the pigmental centers on a retina, waxy pale optic disks, narrowing of retinal vessels. Precursory symptoms of a disease - a hemeralopia, decrease in amplitude of waves of the electroretinogram. Under review characteristic ring-shaped scotoma comes to light. Gradually the field of vision concentrically is narrowed, becomes tubular in this connection the patient loses an opportunity to be guided in space. The field of vision is narrowed, and visual acuity sharply decreases up to a blindness. Process quite often is complicated by development of a cataract, secondary glaucoma, retina amotio.
The course of idiopathic (sclerous) dystrophy progressing with gradual decrease in the central visual acuity.
Retina Dystrophy reasons:
Idiopathic (sclerous) dystrophies are caused by arteriosclerotic changes in vessels of a choriocapillary layer, disturbances of microcirculation in trailer capillaries of a horioidea and a retina in the field of a macula lutea against the background of a hypertension, atherosclerosis.
Treatment of Dystrophy of a retina:
At a pigmental retinitis use vasodilating drugs, энкад, vitamins, компламин, нигексин, Halidorum, niacin, a noshpa, B1, B2, B6, B12 vitamins in the standard doses, ATP, vasoprotectives (Dicynonum, trental), сермион, эмаксипин, фосфаден locally, inside, intramusculary. Repeated courses are conducted in 6-10 months. Under a conjunctiva enter also Flavinatum, biogenic stimulators. Apply physical methods of treatment - ultrasound, electro-and фонофорез, microwave therapy. For improvement of blood circulation and exchange processes vazorekonstruktivny operations are shown, at increase in pressure - antiglaukomny operations, and also extraction of a cataract.
Adequate methods of drug treatment of idiopathic dystrophy do not exist. For the purpose of a delay of progressing of process apply vasoprotectives, vasodilating drugs, corticosteroids retrobulbarno, diuretics, antioxidants, resorptional means. An effective method of treatment is the lazerkoagulyation. For the purpose of improvement of blood circulation in the central area of an eyeground perform vazorekonstruktivny vartikozny expanded vein operations, bandaging of a branch of surfaces of a temporal artery, operation of revascularization of a back pole of an eye.
