[Advances in near work-induced transient myopia].

The possible mechanism of myopia remains controversial while gene and environment are two generally acknowledged factors underlie the development of human myopia. Nearwork which is a primary,environmentally based factor in the development and progression of permanent myopia ( PM ) may take effect via nearwork-induced transient myopia (NITM). In this review,the definition,measuring procedure and relative evaluation parameters of NITM as well as its characteristics,methods for reducing NITM and its possible mechanisms reported in the literature will be summarized.
