Type 2 diabetes - Does diabetes affect the visual part of the brain before causing eye damage?

Having type 2 diabetes is known to increase the risk of vision loss. Of the elderly with type 2 diabetes, 10 to 20% have problems in their eyes and weaken with the age of all people. Approximately 90% of diabetes patients have diabetes mellitus for more than 25 years and then cause changes in blood vessels in the eyes.

Loss of vision is caused by retinopathy, a condition in which the back of the eye is damaged. Damage is often seen behind the brain and back of the head. The occipital lobe processes the information sent from the eye to the brain via the optic nerve. Retinal damage may be thought of as causing (or using it) contractions of the occipital lobe, but the occipital region can sustain the damage of diabetes even before retinopathy occurs.

In August 2017, Graefe 's Clinical and Experimental Ophthalmology archive reported a study completed at Coimbra University in Coimbra, Portugal. Researchers compared the brain ...

• Type 2 diabetic patients without retinopathy
• 27 people without type 2 diabetes.

Participants with diabetes without retinopathy showed occipital lobe atrophy Compared to that of non-diabetic patients. From these results it was concluded that type 2 diabetes may damage parts of the brain before diabetic retinopathy is detected.

Occipital lobe is part of the cerebral cortex where the brain processes its best function. Most visual processing is done in the area known as Brodmann area 17 or Visual 1 's V 1. Information from the visual cortex is sent to the parietal lobe, combined with other sensory information to form an idea of ​​the environment cognition). The parietal lobe develops at the age of 5 and helps the child integrate space, tactile sensation, volume and gain clear vision.

Type 2 diabetes is the most common cause of blindness diagnosed in adults of working age. In more cases of diabetes diagnosed annually, the incidence of blindness is increasing. Worldwide diabetes is the fifth most common cause of blindness. It is mainly derived from diabetic retinopathy. Is the decrease of occipital cortex another cause of diabetes vision loss? Can both problems be played at the same time? More research can find the answer.

However, diabetic blindness is caused and the important thing is to keep the blood sugar level normal. That means keeping on top ...

• Diet,
• Exercise, and
• When medicine is prescribed.

Type 2 diabetes is not painful when first diagnosed, but it can cause a lot of suffering. Please doctors regularly. If you have acute pain in your eyes, consult your eye doctor immediately.
