Anatomical factors behind acquired primary nasolacrimal duct obstruction and acute dacryocystitis.

Purpose: To compare the nasolacrimal and nasal anatomical parameters in cases of acquired primary nasolacrimal duct obstruction and acute dacryocystitis.

Methods: The study included 62 eyes of 31 patients. The eyes were divided into three groups: Group A, comprising eyes presenting with acute dacryocystitis; Group B, comprising eyes with nasolacrimal duct obstruction but no previous episodes of dacryocystitis; and Group C, comprising eyes with an patent nasolacrimal duct.

Incompatibility of Lacrimal Syringing Test with Dacryoscintigraphy in Patients Undergoing Successful Dacryocystorhinostomy Surgery.

 The aim of our study was to evaluate the compatibility of lacrimal syringe test with dacryoscintigraphy (DSG) in the postoperative evaluation of external dacryocystorhinostomy (Ext-DCR) surgery.  Thirty eyes of 30 patients suffering from unilateral epiphora with discharge and showing complete obstruction on lacrimal irrigation test were included in the study. Patients with dysfunctional lacrimal pump function, revision surgery, partial obstruction, and ocular surface diseases were not included in the study.

Assessment of Schlemm's canal with swept-source optical coherence tomography in Graves' ophthalmopathy.

Purpose: To evaluate the Schlemm's canal (SC) parameters obtained by swept-source optical coherence tomography (OCT) different in Graves' ophthalmopathy (GO) eyes compared to healthy eyes.

Methods: This cross-sectional observational study evaluated 64 eyes of 32 GO cases and 56 eyes of 28 healthy controls. The study was conducted between October 2020 and June 2021.

Modified Horner-Duverney's muscle plication in the treatment of functional epiphora.

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.

Evaluation of corneal endothelium and correlation with disease severity in patients with Graves' ophthalmopathy: A specular microscopy-based study.

Purpose: To investigate the possible corneal endothelial damage in Graves' ophthalmopathy (GO) and its relationship with GO activity.

Methods: This cross-sectional study included 101 eyes of 55 patients with GO. Each eye was assigned a specific clinical activity score (CAS).

Importance of etiology in canalicular obstruction surgery.

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.

Efficacy of pyridostigmine (Mestinon) in the relief of patients with epiphora.

Background: Although the mechanism is not clear, the inability of the orbicularis oculi muscle, especially the deeper segment (Horner muscle), is thought to be responsible in epiphora. This study evaluates the effect of the anticholinergic drug pyridostigmine (Mestinon) in patients with patent but dysfunctional lacrimal drainage system.

Material And Methods: Twenty patients with bilateral epiphora (mean age:60.

A Case Report of Conjunctival Extranodal Marginal Zone Lymphoma Treated with Intralesional Rituximab Injection Therapy.

Purpose: To describe the safety and efficacy of intralesional rituximab (anti-CD 20 monoclonal antibody) therapy in a patient with conjunctival extranodal marginal zone lymphoma.

Methods: A single case report from a tertiary referral center.

Results: A 43 years old female patient with low-grade conjunctival extranodal marginal zone lymphoma who was completely and safely treated with intralesional rituximab therapy was presented.

The electromyographic analysis of orbicularis oculi muscle in epiphora.

Purpose: Functional epiphora is a clinical condition that presents with the complaint of watery eyes, but without anatomical stenosis in the lacrimal drainage system. Although the mechanism is not clear, there are various possibilities involving the movement of the orbicularis oculi muscle, especially its deeper segment (Horner's muscle). We aimed to evaluate the function of the orbicularis oculi muscle in patients with patent, but dysfunctional lacrimal drainage system using a quantitative motor unit potential (MUP) analysis.

Characteristics of pediatric and adult cases with open globe injury and factors affecting visual outcomes: A retrospective analysis of 294 cases from Turkey.

Background: This study aimed to evaluate 1-year follow-up results of cases that were diagnosed with open globe injury (OGI), to compare trauma-related characteristics between pediatric and adult cases, and to determine risk factors for a poor final visual acuity.

Methods: This study enrolled 294 cases that met the OGI definition and were followed up for at least 1 year. Demographic and clinical features regarding ocular trauma were recorded.
