Symptoms of retinitis

summary

The main causes of retinitis are edema, exudation and hemorrhage of retinal tissue, which lead to different degrees of vision loss; Generally secondary to choroiditis, leading to chorioretinitis. Etiology is divided into exogenous and endogenous. The visual symptoms were not obvious, mainly manifested as vision loss, even blindness. What are the symptoms of retinitis? Let's talk about it

Symptoms of retinitis

Fundus changes: macular localized gray white or gray yellow exudative lesions, round or oval, unclear boundary, slightly elevated, about 1 / 4 ~ 1 nipple diameter, arc or ring bleeding and hard lipid exudation around the lesions, and may be accompanied by shallow detachment of the posterior pole retina. In the late stage, the lesions were absorbed and the scar tissue was formed.

Fluorescein angiography: neovascularization can be seen from choroidal pigment under the skin or neuroepithelium. The peripheral hemorrhage formed fluorescence shielding. There was a central scotoma in visual field examination. The central visual acuity was decreased and the visual object was deformed.

There were arc-shaped or ring-shaped bleeding at the edge of the lesion, and occasionally radial punctate bleeding. There was a pigmented band around the lesion. Many cases were complicated with discoid retinal detachment, and some had hard lipid exudation. Most of the lesions were centered on the fovea and within the radius of 1pd. At the end of the course, the macular area formed yellow white scar. Fluorescein fundus angiography showed that in the early arterial phase or arterial phase, there were granular, lace and other forms of neovascular network in the exudative focus. The bleeding area was covered with fluorescence, and the upper edge of bleeding had ventilating fluorescence area. In the late stage of neovascularization, there was leakage of fluorescein to form a strong fluorescence area.

matters needing attention

Abstinence diet: the key to abstinence of chronic diabetes is diet, which has different dietary requirements for different types of patients. For example, obese people reduce caloric intake, reduce body weight, increase organism's sensitivity to insulin, and reduce blood sugar; For the emaciated and young children, the caloric intake should be increased appropriately. The total amount of daily meals and the distribution of three meals are relatively fixed. We should eat a diet with low sugar, low fat, high egg white and high cellulose, eat more coarse grains, eat less refined rice, refined white flour and fruits with high sugar, and fast the diet rich in monosaccharide or disaccharide, such as sugar, cakes, ice cream and sweet drinks.
