Diabetes is a condition where the blood glucose level shoots up. In such a scenario, it can affect your eyes depending on the period. During short-term cases, you might not have any serious ailment. However, you can have blurry vision when changing diabetes care medicines. This can cause temporary discomfort but does not stay longer than days or weeks.
For patients who have had diabetes for a long time, the situation becomes much more dire. Prolonged high blood sugar can damage their blood vessels starting from the initial prediabetic stage. Damaged blood vessels can cause serious problems concerning your eyesight. Considering all the factors, we have enlisted few diabetes eye diseases in the following section:
Some diabetic patients find it difficult to view finer details resulting in blurred vision. This generally happens when fluids from blood vessels in your eyes leak into the lens. As a result of this, the lens swells up and changes its shape.
Another instance of blurry vision can be during the initial phase of insulin treatment. This occurs due to shifting fluids in your eyes. However, this gets resolved after a few days when the patient’s blood sugar level becomes stable.
Here are some of the symptoms of blurry vision:
- Clouded vision
- Fading colours
- Double sight
- Light sensitivity
- Glare around lights
- Vision does not improve even after changing glasses
Prolonged blurred vision in diabetic patients means that they have contracted cataracts. The eye lenses offer clear and sharp vision, but they tend to become clouded with age. However, in diabetic patients, this condition occurs early as glucose deposits in the lenses, causing blurry vision.
Cataract patients have to undergo surgery where doctors remove the clouded lens with an artificial one. Some symptoms of cataract include:
- Unable to focus on an image due to cloudy vision
- Colours in images start to fade during this condition
In this ailment, the optic nerve becomes heavily damaged. The optic nerve is a bundle of nerves connecting the eye to the brain. Diabetic patients are prone to this condition, which can cause loss of vision if not treated early.
There are three types of glaucoma that patients should be aware of - open-angle, angle-closure and congenital glaucoma. Open-angle glaucoma is highly prevalent in the United States. Further, it is important to note that there is no cure for glaucoma. However, early treatment and medical attention can help prevent blindness.
Here are some symptoms to monitor for an early diagnosis:
- Peripheral vision loss
- Glare or halos around eyes
- Eye reddening
- Ocular pain or pain in the eyes
- Vomiting or nausea
Damage caused to the retina of an eye results in a condition diabetic retinopathy. The retina is the inner lining of the anterior portion of an eye that absorbs light and turns them into signals. These signals reach the brain and enable vision. However, high blood glucose can cause damages to the blood vessels that affect the retina and develop into this condition.
During the early stages of non-proliferative diabetic retinopathy, weakening, bulging or leaking blood vessels into the retina occur. However, if the existing blood vessels get clogged, new ones arise on the retina resulting in serious vision problems. This stage, also known as proliferative diabetic retinopathy, is a serious condition that develops later.
Detection of early symptoms in this medical condition is not possible as they are not long-lasting. However, with time, patients can observe the following signs:
- Dark floating spots (bleeding of blood vessels in the retina into the vitreous)
- Trouble in viewing faraway objects
Sometimes, this condition may worsen and lead to other serious ailments like neovascular glaucoma, retinal detachment and diabetic macular oedema.
Diabetic Macular Oedema
The macula is the part of your retina that aids in reading, driving and viewing faces. Diabetic conditions can result in macular swelling, which causes diabetic macular oedema. As a result, a patient’s sharp central vision is lost. Such instances can lead to partial or complete blindness.
Moreover, as this condition stems from diabetic retinopathy, symptoms are the same. Some other symptoms can be colour changes and wavy vision. Therefore, patients with signs of diabetic retinopathy should get diagnosed at the earliest so that treatment can begin.
This is a type of glaucoma that originates from diabetic retinopathy. In this condition, there is an abnormal growth of blood vessels from the retina that blocks fluid from draining out of your eyes.
Due to excessive bleeding from blood vessels, scars can occur at the back of your eyes. Owing to these scars, the retina gets pulled away from the back of your eyes, resulting in tractional retinal detachment.
However, there are certain risk factors associated with these diseases.
