Eye Symptoms ( or Visual Problems ) that originate from the body system – Diabetes.
The eye disease that develops in diabetes is called diabetic retinopathy which occurs as a result of changes in the cells ( mural cells) that line blood vessels of the eyeball. Normally mural cells are leakproof (i.e. it does not allow blood to leak out of the blood vessels of the eye). But in diabetes, these mural cells are weakened therefore blood leaks into the eye causing tiny haemorrhages (blood) and exudates (yellowish spots) in the retina (back of the eye). This is what happens in diabetic retinopathy.
Sometimes, sugar pellets in diabetes can block the small blood vessels which could lead to a blockage. If this occurs, the blood vessel may not be able to carry enough oxygen to the eye, the body responds quickly to this by growing new tiny blood vessels at the site of blockage. These new vessels are actually fragile and can break easily which can cause leakage of blood into the vitreous and in turn cause a loss of functional vision.
The retina ( back of the eye) is so metabolically active, disease like diabetes may be obvious in the eye before they produce symptoms elsewhere in the body. Getting a regular eye exam in a standard eye clinic and from a competent eye doctor will pick these signs and discuss them with you early enough.
