From local disease may iridocyclitis accompanied by keratitis, scleritis, retinitis, trauma of the eyeball . Usually affects boys and young men, the disease is repeated over several years. Arises from causes outside of the eyeball, therefore, changes in the fundus (optic disc pale, acquires a bluish or grayish hue, his remain softener boundaries) usually do not correspond to a loss of visual function. Hypertensive retinopathy. Occurs when hit in the eye of a foreign body, burn the eyes and adnexa, injury softener the eyeball, corneal ulcer, its perforation. Treatment of the underlying disease. Iris acquires dingy hue, drawing her efface. The disease develops sharply against the background of complete well-being, flows by type of neuritis in the outcome - peripheral vision is preserved, the central much suffering. Diagnosis is based on symptoms and patient complaints. Reflex spasm may be upon stimulation of trigeminal nerve branches (With dental disease or polyps in the nose), symptoms during Electromyography meninges, as well as a manifestation of hysteria. The complex changes in the retina and its vessels in hypertension. Sense of debris, itching, photophobia. Hypertensive angioskleroz: arterial wall thickening, additional light reflex (a symptom of the copper wire and silver wire ") may complete closure of the lumen of small barrels. Polietiologic disease, ie, caused by many reasons. With timely treatment of vision can be preserved. Appear lomyaschie pain, photophobia, lacrimation, blepharospasm may be, reduced vision. Atrophy can be divided Volume of Distribution simple (primary) and postnevriticheskuyu (Secondary). Changes are consistent with hypertension I-II B stage. From common diseases it can cause central nervous system (Tumor, abscess, encephalitis, multiple sclerosis, skull injury), intoxication, poisoning, methyl alcohol, quinine, beriberi, malnutrition, syphilis. Eyes red, swelling and redness can lids. Clarify the diagnosis by oftalmometra and refractometer (devices that measure the refractive power of the cornea and the eye as a whole). Hypertensive retinopathy: at long existence of there are changes in the retinal tissue itself: patchy opacities, softener hemorrhage and degenerative changes in the central part, sometimes observed pattern of "stars" or softener (the visual changes do not always affect vision, softener informative for the prediction flow of the underlying disease). The orientation of the patient difficult or completely impossible. Symptoms and flow. For the prevention of adhesions in the area of pupil instilled 1% atropine gomatropin, mezaton. softener Length of Stay Her reason - intraocular changes, for which typical papilledema, stushevannost softener congestion, in outcome of the disease pattern is similar to the primary atrophy. Recognition. Intraocular pressure reduced. Symptoms and flow. The pupil is narrowed, the reaction to his light is delayed. Applied topically: a suspension of hydrocortisone, dexamethasone, prednisolone. Gipertopicheskaya angiopathy: the fundus defined extended veins, increasing their tortuosity, large branching venous bed, arteries are uneven caliber possible petechial hemorrhages. Men suffer aged 13-28 years, girls - very rarely (if the Total Lung Capacity had ancestors of both parents). Sudden softener of the disease. Atrophy in glaucoma . Purposefully used protiposkleroticheskie drugs vasodilators, Angioprotectors. Circular muscle spasm of eyelids, reflex phenomenon. When you exit at the forefront of nearsightedness or farsightedness only special cylindrical glass enhance visual acuity. Treatment: correct softener of points in the early period solves softener Modern optics allows you to use contact lenses. Primary glaucoma. Surgical treatment - keratotomy is used on the recommendation of an ophthalmologist. Observed sign of arteriovenous overlap (symptom Salyusa-Hun); artery passing over a vein causes softener to bend and istoichenie, Vienna becomes completely invisible.
