Shortened Fornix Syndrome After Posterior-Approach Ptosis Repair

SFS, characterized by symblepharon, fornix shortening, and associated functional issues including ptosis and restricted eye movements, is a rare but significant complication of posterior-approach ptosis repair. Only one prior report has documented a similar entity in patients after conjunctival Müller muscle resection using glaucoma drops; interestingly, the authors' cases occurred in patients without significant ocular surface or topical ocular medication use, suggesting SFS can develop independently of such treatments. Prevention strategies include meticulous intraoperative technique and a cautious approach to large resections or repeat posterior-based surgeries, with consideration of anterior-based techniques if appropriate. Management of SFS via a staged approach involving ocular surface reconstruction followed by anterior-based ptosis repair may lead to satisfactory outcomes. Awareness of this complication is crucial for proper patient selection and management of ptosis.
