The development of marked conjunctival chemosis following vitreoretinal surgery may be due to extensive intraoperative cryopexy, prolonged surgical time, removal of edematous corneal epithelium, and postoperative face-down posturing for an intraocular gas bubble. The fine suspensory attachments of the conjunctival fornix may be disrupted by the hydraulic dissection of marked chemosis, leading to prolapse of the conjunctiva through the eyelids. This problem can be successfully managed by a combination of conjunctival fornix sutures to invaginate the prolapsed conjunctiva and temporary suture tarsorrhaphy.
玻璃体视网膜手术后出现明显结膜水肿，可能是由于术中广泛应用冷冻疗法、手术时间延长、去除水肿的角膜上皮以及术后为使眼内气泡吸收而采取的面朝下体位。明显结膜水肿的水分离操作可能会破坏结膜穹窿的精细悬吊附着结构，导致结膜经眼睑脱出。通过联合应用结膜穹窿缝合术使脱出的结膜内陷和暂时性睑裂缝合术，可成功解决这一问题。
