Some types of blindness occur as a result of preventable disease in the retina.
The main methods for reducing the percentage of preventable blindness is to detect the disease early and immediately begin proper treatment.
There are three diseases that arise from treatable retina problems:
Age-related macular degeneration (ARMD): This condition can be prevented and its progress can be avoided by maintaining a diet that is rich in fruits and vegetables, includes high levels of zinc and antioxidants, and includes foods that are rich in omega-3 such as oily fish. See a specialist upon the first sign of symptoms such as sudden onset blurry vision, distorted vision, the appearance of faded colors or the appearance of spots.
Diabetic retinopathy: This condition affects people living with diabetes and can be prevented by properly monitoring glucose levels as well as blood pressure, cholesterol and triglycerides. Maintaining a healthy lifestyle through eating healthy and doing consistent exercising and physical activity can help control these factors.
High myopia: Regular eye exams are critical to getting an early diagnosis and can help prevent the complications related to this disease. According to the Institute for Ocular Microsurgery in Spain, this condition occurs when vision errors are greater than 8 diopters. This is why it is very important for patients that suffer from myopia to have regular checkups and to be aware of any changes in their vision such as seeing flashes or spots.
A report on blindness in Spain conducted by Fundación Retinaplus, relates that there a million people in this country living with visual impairments caused by these diseases.
