Kinds of Eyes Diseases Caused by Diabetes
Diabetes is a common endocrine disease, sounding like there is no significant relationship with eyes. Actually, it is not. Currently, direct acute complications caused by Diabetes are rarely seen in clinic, such as ketoacidosis and hyperosmolar coma. The greatest harm caused by Diabetes is chronic complications. Diabetic eye disease is one of the most common chronic complications. What kinds of eye diseases do you know? Eye diseases caused by Diabetes are as follows.
Retinopathy is the most common severe diabetic eye disease, often resulting in vision loss or blindness. According to statistics, 50% patients with the duration of 10 years can have this disease and it is 80% for more than 15 years. The severer the illness condition is, the older patients are and the higher of occurrence. Retinopathy is the result of diabetic microangiopathy. Because retinal capillary wall damages caused by Diabetes combined with blood hypercoagulability, it will result in thrombus, stasis and even rupture of blood vessels.
It is reported that blind chance for Diabetics is 25 higher than that of non-diabetics. Currently, Diabetic retinopathy has become one of four blinding factors, ranking after age-related retinal degeneration. The early treatment for Diabetic Retinopathy is still ideal and the cost of early prevention is far lower than that of late treatment. Therefore, it is very important for the prevention of eye diseases to avoid or delay the occurrence.
Cataract caused by Diabetes accounts for more than 60% of the total number of cataract patients. The surgery rate is much higher than that of other cataract patients, so generally it requires surgery. Animal experiments have confirmed that hyperglycemia in vivo and in vitro experiments can lead to cataract, arousing our attention.
Fluctuations in refractive error
Many patients don’t know that they have Diabetes. After a long time, they may find that they are shortsighted suddenly. Actually, it is the reason of Diabetes. Patients take glasses and their eye sight return to normal. At this time, if patients check their blood sugar for several times, peaks and troughs must be found, which means volatility elevated blood sugar.
When blood sugar increases sharply, patients may suddenly become myopic eyes or the original presbyopia symptoms alleviate. When blood sugar reduces, it can also restore to emmetropia or patients wear presbyopic glasses. Therefore, fluctuations in blood glucose can cause vision changes in volatility.
Diabetes can cause open-angle glaucoma easily, which is called chronic simple glaucoma. Such kinds of glaucoma can be found in middle-aged people and youth. It is often bilateral and has slow onset. Intraocular pressure increases gradually. There are no obvious symptoms, which can be found when there is obvious damage. Therefore, early diagnosis is very important.
There is no obviously uncomfortable in early period. When it develops into a certain degree, patients may feel mild headache, eye pain and blurred vision. These symptoms can disappear automatically, so it may be mistaken as eye fatigue easily. Central vision can be maintained to be unchanged for a long time, but vision impairment occurs early. In the end, optic nerves atrophy gradually because of long-term oppression of high intraocular pressure.
Eye movement paralysis
Diabetes can lead to arteriosclerosis, resulting small blood vessels ischemia of eyelid nerves. In addition, Diabetics may have eye movement paralysis, causing extraocular muscle movement disorders and diplopia, such as abducens nerve palsy or oculomotor nerve palsy. For example, some elderly people may have dropping eyelid and can’t open their eyes, which is thought as eye disease or gravis. So patients should take acupuncture, physiotherapy and infusion to avoid delaying of best correct treatment time.
It is also called vscular pseudo-papillitis, which can be found in elder people with one or two eyes having this disease. The main clinic manifestation is sudden change in vision and vision. Vision becomes blurred suddenly, reducing to blind. Vision is initially fan-shaped defect below the nose and then it extends to hemianopia or concentric narrowing.
