[Spontaneous regression of the retinopathy of prematurity].

Retinopathy of prematurity (ROP) has become the leading cause of childhood blindness worldwide. It is the key point of ROP prevention and treatment to screen out and deal with severe ROP that require treatment. However, more than 70% ROP regressed spontaneously without treatment. It is useful in deeply understanding the natural course of ROP and is helpful to develop strategies of ROP screening and prevention, that the characteristics of spontaneous regression of ROP are investigated comprehensively. The epidemic characteristics, clinical features, time course, related factors and visual impairment of ROP regression will be systematically summarized in this review.(Chin J Ophthalmol, 2021, 57: 150-155).
