What are the fundus diseases? Experts point out: our eyes are like a camera, and the fundus is the “negative” of the eyes. If there is a problem with the negative, the picture will be distorted, and once the fundus is diseased, life will no longer be colorful. What are the diseases of the fundus? Experts at Ningbo Eye Hospital point out that what is commonly called the fundus includes the retina, choroid and optic nerve papillae. Lesions in any one of these areas, resulting in vision loss, dark shadows in front of the eyes or visual field defects, can be called fundus disease. Fundus disease can occur at different ages, fundus disease mainly includes: 1, age-related macular degeneration: common macular degeneration caused by aging, is the main cause of blindness in people over 60 years old. 2, diabetic retinopathy: is the ocular manifestation of diabetic microangiopathy. The incidence increases as the duration of diabetes increases. 3, retinal vein obstruction: caused by high blood viscosity, vascular sclerosis, etc., commonly in the elderly, more than 90% of patients are over 50 years old. 4.High myopia macular degeneration: macular hemorrhage, neovascularization and even scar formation caused by high myopia, which is the main cause of blindness in young and middle-aged people. 5, central plasmacytoid chorioretinopathy: mostly seen in young and middle-aged men, often with monocular onset, with a tendency of self-healing and recurrence. The etiology is unknown, mental stress, emotional excitement, infection, allergy, etc. can contribute to the development of this disease. 6, retinal degeneration, fissure, detachment: mostly caused by myopia, trauma and other reasons, the impact on vision varies depending on the location and extent of the lesion. 7.Hemangioma: It can occur in the retina or choroid. There are different types of hemangiomas and different ages of onset. How to treat fundus disease? 1, etiological treatment: for fundus disease secondary to medical disease, blood sugar and blood pressure should be controlled, and blood lipids and blood viscosity should be improved; 2, pharmacological treatment: improve fundus microcirculation, activate blood circulation and remove blood stasis; 3, laser treatment: use different mechanisms of laser action, such as laser photocoagulation, transpupillary thermotherapy (TTT), photodynamic therapy (PDT), etc. can close leakage, improve retinal edema, close neovascularization, make 4.Surgical treatment: For severe bleeding, severe proliferation and larger tumors, surgical methods should be used for treatment.
