Abstract:Aggressive posterior retinopathy of prematurity (AP-ROP) is a special kind of ROP, which is characterized by ill-defined, dilated and tortuous vessels in the posterior portion of the eye and rapidly progresses to severe ROP with retinal detachment. As more and more AP-ROP cases, who usually have poor prognosis, have been found, this disease has been increasingly noted. Which premature infants are at risks? How to make earlier diagnosis? Is there any better treatment protocols? There is much research about AP-ROP and this article summarizes the risks, screening, diagnosis and treatment of this disease.
