Research progress of clinical application of posterior scleral reinforcement / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#Posterior sclera reinforcement(PSR), also known as posterior sclera strengthening or posterior sclera bandage, is a kind of operation to fix biological or non-biological materials to the posterior sclera, with the aim to strengthen sclera and improve the blood circulation of the choroid and retina by using the traction of materials or the immune inflammatory stimulation, thereby delaying the continuous extension of the axis and improving visual function. The main indications of PSR include pathologic myopia(PM)and its related complications. In addition, PSR can also help to improve blood circulation at the posterior pole of the eye in patients with retinitis pigmentosa(RP), especially in conjunction with superficial temporal artery ligation. After more than half a century's development, PSR has been currently considered as one of the few and effective methods to treat PM and RP, but as a more traumatic operation, the stability of its clinical effect varies greatly, so there is still room for improvement in surgical procedures and materials used.
