To report two cases of rhegmatogenous retinal detachment (RRD) associated with asteroid hyalosis (AH).
Two patients presented with RRD originating from a flap tear. Case 1 involved a 62-year-old male who was found to have bullous RRD in his left eye originating from a flap tear. During vitreous surgery, a thick vitreous cortex was found to have strongly adhered to the entire retinal surface, from the center to the periphery. A bimanual method was then used in conjunction with the vitrectomy to create an artificial posterior vitreous detachment. After surgery, the retina was successfully reattached, and his corrected visual acuity (VA) improved. Case 2 involved a 70-year-old male who was found to have localized RRD in his left eye originating from a flap tear. During vitreous surgery, a thick vitreous cortex was found to have strongly adhered to the entire retinal surface. After surgery, the retina was successfully reattached, and his corrected VA improved.
RRD associated with AH presents with stronger vitreoretinal adhesion compared to typical RRD, thus requiring a more complicated surgical technique to properly treat the patient.
报告两例与星状玻璃体病变（AH）相关的孔源性视网膜脱离（RRD）病例。
两名患者均因瓣状裂孔导致RRD。病例1为一名62岁男性，其左眼因瓣状裂孔出现大泡性RRD。在玻璃体手术中，发现厚厚的玻璃体皮质从中心到周边牢固地附着于整个视网膜表面。然后在玻璃体切除术中采用双手操作方法形成人工玻璃体后脱离。术后，视网膜成功复位，其矫正视力（VA）提高。病例2为一名70岁男性，其左眼因瓣状裂孔出现局限性RRD。在玻璃体手术中，发现厚厚的玻璃体皮质牢固地附着于整个视网膜表面。术后，视网膜成功复位，其矫正VA提高。
与典型RRD相比，与AH相关的RRD表现出更强的玻璃体视网膜粘连，因此需要更复杂的手术技术来妥善治疗患者。
