Question
High myopia is classified into mild, moderate, and high myopia, with high myopia further divided into simple high myopia and pathological myopia. How can pathological myopia be identified?
Answer
Pathological myopia is an eye disease different from simple myopia, characterized by heredity and unrelated to eye strain. It manifests as a continuous deepening of myopia, accompanied by changes in the retina due to excessive eye axis elongation. If the degree of myopia increases by more than -1.00D in a year, or even reaches -2.00D or above, or if the cumulative degree reaches -20.00D of high myopia, it is likely to be pathological myopia. Pathological myopia requires timely medical treatment to prevent further deterioration of vision.
