ABSTRACT

Objective To investigate the occurrence, progress and conversion of hypotony in anterior proliferative vitreoretinopathy (aPVR), and to provide knowledge about how to prevent and treat it. Methods Animal models of chronic hypotony by aPVR were made with cultured homologous dermal fibroblasts on pigmented rabbits. The intraocular pressure (IOP) and ultrasound biomicroscopy(UBM) examination were taken preoperatively and on days 7,14, 28 and 56 postoperatively. Rabbits were killed on days 14, 28 or 56 postoperatively, prepared for histology and ultrastructure examination. Results The average IOP of experimental group was lower than that of control group on days 7,14,28 and 56 significantly (P
