Abstract

P: Role of Computed Tomography–Dacryocystography (CT – DCG) in Traumatic Secondary Acquired Lacrimal Duct Obstruction (T-SALDO)
M: Retrospective interventional series of 65 lacrimal drainage systems(LDS) of 60 patients of T-SALDO, undergoing CT-DCG, between January 2019–2023. Successful outcome following lacrimal intervention was patent irrigation and nil-minimal epiphora, or absent discharge in Dacryocystectomy(DCT), at 1 month
R: CT – DCG revealed dilated sac in 52, shrunken in 10, and no visualization in 3 cases. Sac displacement(62) was posterior in 37%; superior in 16.9%; anterior in 9.6%; inferior in 3.2%. Screw/implant directly penetrated sac in 5 LDS, 4 had diverticula and 24 had hyperostosis. CT – DCG findings corroborated with surgical findings in 46 (95.83%). Of 48 operated cases, endoscopic dacryocystorhinostomy was most common(47.9%), followed by external(37.5%), and DCT(14.6%), with success achieved in 98% cases
C: CT-DCG aids in successful management outcomes in T-SALDO
