The rate of fundus positivity is not related to gender, but there is a close relationship with the age of the patient, and the older the patient, the higher the rate of positivity. In patients with chronic hypertension, the rate of fundus positivity is directly proportional to the duration of the disease, and the rate of fundus positivity is higher in patients with longer disease duration. What is the diagnosis of fundus punctate or flame-shaped hemorrhage? 1, fundus punctate or flame hemorrhage fundus hemorrhage is not an independent eye disease, but a feature common to many eye diseases and certain systemic diseases. It is commonly seen in retinopathy caused by hypertensive retinopathy, diabetes mellitus and nephropathy. Retinal perivasculitis, retinal vein obstruction, optic disc vasculitis, and hematologic diseases cause retinopathy, and fundus hemorrhage from ocular trauma. Due to various etiologies leading to the same pathological damage, such as retinal hemorrhages, exudates, microangiomas, neovascularization, etc. Because of the complex etiology of this disease, it has a long course and is prone to recurrent attacks, which seriously affects vision and causes many serious complications. Such as macular degeneration (macular cystoid edema, macular degeneration), neovascular glaucoma, vitreous hemorrhage, optic nerve atrophy, proliferative retinopathy, retinal detachment, if not timely and effective treatment, can often lead to blindness. 2.The macula is found to be grayish discolored in the fundus of the eye Austin-type cerebral sulphur lipidosis in young children, also known as Austin-type heterogeneous cerebral white matter dystrophy, is a combined disease of cerebral sulphur lipidosis and mucopolysaccharide storage disease. It is characterized by a mild Hurler syndrome face, multiple bone dysplasias, severe neurological symptoms and marked mental retardation. Fundus examination can reveal a grayish discoloration of the macula and later even blindness. 3, cherry red spots in the macula of the fundus Niemann-Pickrsquo;s disease (Niemann-Pickrsquo;sdisease, NPD) is a hereditary metabolic disease due to the deposition of sphingomyelin and cholesterol in various organs of the body, with a high incidence in young children, with large liver, spleen, cherry red spots in the macula of the fundus and large foam-like cells in the bone marrow smear, etc. The main features of the disease are large liver and spleen, cherry red discoloration of the macula in the fundus and large foamy cells in bone marrow smears. The first case was reported by Niemann in 1914, and in 1922 Pick described in detail what was seen on pathological examination, hence the name. Two cases were first reported in China in 1963, and individual cases have been reported since then.
