Polokwane doc on diabetes eye complications

POLOKWANE – “Patients with diabetes are at risk of developing eye problems, the most common being diabetic retinopathy.”

This is according to diabetes specialist Dr Mabowa Makhomisani who explained that diabetic retinopathy occurs when diabetes causes continuous damage to the retina, the light-sensitive layer at the back of the eye.

In an interview with Polokwane Observer, Makhomisani emphasised the seriousness of this condition, noting that blindness is the most severe complication.

“Diabetes impairs the body’s ability to regulate blood sugar. Persistent high blood sugar levels damage blood vessels throughout the body, including those in the eyes. Over time, these blood vessels can harden, crack, and bleed, leading to poor blood supply to the vision centre, which can ultimately cause blindness if untreated.”

He added that individuals with long-term diabetes are at higher risk of developing eye problems.

“Symptoms include seeing dark spots or floating strings, fluctuating vision, and blurred vision that doesn’t improve with glasses. Immediate medical attention is crucial if these symptoms arise.”

Makhomisani shared concerning statistics, saying that half of all patients with type one diabetes and one-third of those with type two, will experience eye complications related to the disease.

“Many diabetic patients do not undergo regular eye exams, which are essential for early detection and treatment. Maintaining blood sugar levels between 4mmol/l and 10mmol/l significantly reduces the risk of diabetic blindness.”

He concluded by saying that diabetic eye diseases are a devastating but preventable complication.

“While treatments exist, prevention through lifestyle changes – such as staying active, eating a healthy diet, avoiding obesity, and following prescribed medication – remains the most effective approach.”
