The combination surgery in Group C and simple posterior layer advancement of the LER in Group B provided complete surgical success. The present study suggests the importance of preoperative evaluation of horizontal laxity, allowing surgeons to perform the least amount of surgery to achieve success.

ABSTRACT.Purpose: This study aimed to evaluate the clinical efficacy of canalicular laceration repair using monocanalicular intubation with Monoka tubes. Methods: A total of 36 single lacerated canaliculi were repaired using monocanalicular intubation with Monoka tubes, without mucosal anastomosis of the canaliculi, and were retrospectively reviewed. Demographic information, injury locations, associated ocular injuries, complications and outcomes were analysed. Results: Mean patient age was 34 years (range 1-64 years). Tubes were removed at a mean of 4.2 months (range 3-6 months). There were 26 lower canalicular lacerations (72%) and 10 upper canalicular lacerations (28%). Overall, 34 of 36 cases (92%) showed improvement in symptoms and exhibited positivity on the dye disappearance test at 4-12 months after the procedure (mean 7.8 months). In total, 21 patients (58%) achieved complete success, 13 patients (36%) achieved partial success and two patients (6%) suffered surgical failure. Complications were seen in five cases and included two early tube protrusions, two punctal slits and one punctal granuloma. Conclusions: Monocanalicular intubation with Monoka tubes leads to successful outcomes without significant complications and offers an alternative to bicanalicular intubation in the treatment of monocanalicular lacerations.

Although there was no significant difference between the success rates of the 2 groups, MCI allowed technical ease of insertion and tube removal. Moreover, the tubing does not threaten the unprobed part of the lacrimal drainage system. These advantages of MCI should be considered when selecting treatment methods for CNLDO.

The diffusivities and FA reflected changes in the optic nerve before dysthyroid optic neuropathy in TED. The FA, in particular, reflected TED activity and severity.

In our study, increased contrast sensitivity and improved functional visual acuity after upper eyelid blepharoplasty were caused by changes in ocular HOA and the degree of lash ptosis after surgery. There were no changes in corneal topography or astigmatism.
