Abstract
Purpose :
Fasanella-Servat operation (FSO) was previously reported to be associated with postoperative dry eyes due to accessory lacrimal gland resection during the surgery. The purposes of our study was to investigate the histological characteristics of the excised tissue in the FSO preformed in our institution and explore eventual correlation with post-operative dry eye symptoms and corneal keratopathy.
Methods :
We performed a retrospective, cohort study to determine the frequency of lacrimal tissue resection during FSO, performed at New York-Presbyterian Weill Cornell in 2013-2015, and its correlation with post-operative eye dryness and keratopathy.
Outcomes included study of the pathological specimen for presence of lacrimal tissue and other pathologic findings (conjunctival inflammation, and degree of tarsus resected). Post-operative dry eye symptoms and pre- and post-operative corneal epitheliopathy were also recorded.
Results :
Of the 53 patients who underwent a Fasanella-Servat operation, 7 were excluded due to lack of pathology specimens.
46 patients with a total of 58 eyelid resections were studied. 8 eyelids (13.7%) were found to have lacrimal tissue present in their histopathological specimens.
Post operatively, 9 patients reported some symptoms of dry eye and new onset keratopathy was noted in 4 eyes (6.8%), only one of which had lacrimal tissue present in histopathology specimen obtained from surgery.
Conclusions :
Previous studies found lacrimal tissue present in up to 43% of specimens resected during FSO. Our study is one of few to examine histopathological resections from the FSO and found a much lower rate of lacrimal tissue resection during the operation. We did not find a statistically significant association between lacrimal tissue resection and post-operative dryness or epitheliopathy.
