Background: The orbicularis oculi muscle, especially its part (Horner-Duverney's muscle), which is surrounded by the pericanalicular and located deep in the lacrimal sac, is of primary importance in all stages of tear fluid flow.
Purpose: This study aimed to demonstrate that tightening the pretarsal-preseptal orbicularis oculi and Horner-Duverney muscles may improve the function of the lacrimal pump and may be a surgical alternative for treating functional epiphora.
Material And Methods: This was a prospective interventional case series of 28 patients with functional epiphora.
Purpose: The treatment options for canalicular obstruction remain controversial, and there are different approaches. In this study, we aimed to evaluate the success of balloon dilatation and silicon tube intubation according to the etiology in patients with canalicular obstruction.
Methods: The files of 91 patients with isolated monocanalicular obstruction were retrospectively reviewed.
Objective: To compare tear fluid levels of matrix metalloproteinase 9 (MMP-9) and IL-1ß cytokines between healthcare workers wearing facial masks and controls with correlations in clinical findings.
Methods: In a prospective, controlled clinical trial tear fluid was analyzed for MMP-9 and IL-1ß levels using a commercially available test (Invitrogen; Thermo Fisher Scientific Inc. Waltham, Massachusetts, USA).
Introduction: To introduce the surgical results and examine the effect of intraocular tamponades on surgical outcomes in patients with coexisting macular hole (MH) and rhegmatogenous retinal detachment (RRD) without high myopia.
Methods: This retrospective, cross-sectional, two-center study was carried out with 29 eyes of 29 patients. The patients were divided into two groups according to the intraocular tamponade used in surgery: silicone oil (Group 1) and CF gas (Group 2).
