People’s eyes like a camera, the eye is equivalent to the film, the eye condition is directly related to the imaging of visual quality that is good or bad.Fundus diseases, including the retina, choroid, such as the optic nerve inflammation, tumors, various types of vascular disease, as well as multi-systemic disease caused by eye disease, and some can be serious damage to visual function.

The most common ocular fundus have diabetic retinopathy (DR), age-related macular degeneration (ARMD) and retinal vein occlusion (RVO), and so on.

DR prevention and treatment to control blood sugar

Diabetes is the body due to insulin relative or absolute caused by the lack of sugar, fat and protein metabolism. It is mainly the small blood vessels damage the retina, capillary endothelial cells of early injury to the loss of barrier function, there effusion, edema, followed by capillary obliteration, the emergence of a wide range of retinal ischemia-induced angiogenesis, macular degeneration complicated by the end, the vitreous Blood, traction retinal detachment, and so on, vision and even blindness seriously affected.

Diabetic retinopathy (DR) occurred in the development and the type of diabetes, blood glucose control as well as the length of the course and other relevant circumstances. Related information: â…¡ type 2 diabetes found that just 25% when the existence of DR. 5-year course of the following persons DR incidence of 38% to 39%; 5 to 10 years were 50% to 56.7%; more than 10 years, the incidence increased 69% to 90%. Poor control of blood sugar in diabetic patients 20 years after more than 80% occurred DR, and good control of blood sugar DR incidence rate of 10%.

ARMD causes of decline

With the increase in age, which occurred in the retinal macular serious blinding eye disease incidence increased significantly.Age-related macular degeneration (ARMD) is usually a first incidence ultimately affected his eyes. And the incidence of retinal pigment epithelial cells of metabolic functions related to the recession. In general, dry ARMD occurred in more than 50 years of age, the vision for the often slow to carry out or decline, as the deformation of material; wet ARMD is more than 60 years of age occurred in the elderly, often sudden visual impairment, and with the course of progress can lead to blindness. It is estimated that in 2020 to about 7,500,065 over the age of the elderly and blind as a result of ARMD. As a result, for choroidal neovascularization (CNV), development of awareness and prevention a long way to go. The CNV is very easy to rupture, bleeding, scar formation, damage to the organizational structure of the macular region, resulting in the loss of central vision.

RVO course of a long slow

Retinal vein occlusion (RVO) usually associated with the occurrence of high blood pressure, high cholesterol and other related. Since the onset of retinal vein thrombosis, blood returning blocked vein pressure, retinal vein tortuous expansion, retinal hemorrhage, edema, exudative; at the same time increase the venous pressure to reduce blood flow so that the retinal artery, causing retinal ischemia missing Oxygen damage.Long course of slow, often late because of cystoid macular edema and neonatal complications such as blood vessels to make a serious decline in vision and even blindness. RVO the extent of the damage caused by the main vein occlusion depends on the location and severity of thrombosis, as well as the elimination of the speed of the formation of collateral circulation or not, and so on.

Experts prescription of the four principles

Fundus disease is often advanced to the development of visual function in patients with serious implications of such diseases and there was no magic cure, early detection, early treatment is important.

First of all, attention should be paid to a number of related systemic disease of the original treatment and control; Second fundus disease screening for people at risk, even if no obvious symptoms, should also be on a regular basis to the specialist hospital for examination and fundus vision for the early detection of abnormal; Third If vision loss, or Shiwumohu deformation, and other visual anomalies should immediately seek medical treatment for the treatment of the time; IV diagnosis already is being treated patients with fundus diseases, it should be followed up on a regular basis to understand the development of the disease, in time to adjust treatment Program to reduce serious complications.
