Common refractive errors, such as nearsightedness and farsightedness, are widespread. Cataracts are another common cause of vision loss, making patients see through a haze or with a yellowish tint. Dry eyes often manifest as a burning sensation, redness, or grittiness, especially after prolonged use of electronic devices. However, many eye diseases progress silently, necessitating regular check-ups for long-term vision protection.
Diabetes silently damages the eyes
Diabetes not only affects blood sugar levels but also damages small blood vessels throughout the body, including those in the eyes. One of the most dangerous complications is diabetic retinopathy, a leading cause of vision loss.
When blood sugar levels remain high for extended periods, the blood vessels nourishing the retina become damaged, leaking or blocked, leading to gradual vision loss over time. The disease often presents no clear symptoms in its early stages, making it easy to overlook.
Some signs that may appear as the disease progresses include blurred vision, fluctuating vision, or the appearance of dark spots in the field of vision. However, by the time these signs are noticed, the damage may already be severe.
Glaucoma: a potential cause of blindness
Glaucoma, characterized by increased intraocular pressure, can cause blindness, yet it progresses silently and painlessly. The condition typically begins with peripheral vision loss, while central vision remains intact for a long time, making it difficult for patients to detect. The primary cause is elevated pressure within the eye, which damages the optic nerve. Once this nerve is damaged, lost vision cannot be restored.
Because there are no clear symptoms in the early stages, many people only discover glaucoma when their vision has already significantly deteriorated. However, with early detection, treatment can help slow or halt the disease's progression.
The link between diabetes and glaucoma
Diabetes and glaucoma are not only dangerous individually but are also closely linked. Individuals with diabetes face nearly double the risk of glaucoma compared to healthy individuals, as prolonged high blood sugar damages the blood vessels supplying the optic nerve and increases intraocular pressure. Notably, in patients with long-standing diabetes or poorly controlled blood sugar, the risk of glaucoma may appear earlier and progress faster.
Both diabetes and glaucoma share the characteristic of silent progression. Symptoms are often vague and easily mistaken for eye fatigue or aging. Therefore, waiting until symptoms become obvious before seeking medical attention may mean missing the "golden time" for treatment.
To reduce the risk of eye damage, individuals with diabetes need to maintain good blood sugar control, undergo regular eye examinations, and adhere to prescribed medications. Maintaining a healthy lifestyle, adopting a scientific diet, and reducing stress are crucial. Moreover, getting eye checks after age 40 or if you have underlying health conditions helps detect abnormalities early and limits the risk of vision loss.
