NCT ID: NCT06428266 Completed - Clinical trials for Lacrimal Duct Obstruction

Closed Dacryointubation vs Bicanalicular Intubation for Proximal Tear Duct Obstruction

DICvsBIcanal
Start date: July 1, 2021
Phase: N/A
Study type: Interventional

In Mexico, upper lacrimal duct obstruction (ULDO) is a common pathology, and the standard surgical treatment is closed dracryointubation. Based on statistics from our headquarters, in 30% of cases there is a failure of the technique and recurrence of symptoms due to associated complications. Because of this, the application of a self-stable bicananlicular intubation set is proposed. The aim of this study is to describe the difference in efficacy and complication rate between the application of the self-stable bicanalicular intubation set II (FCI) and closed dacryointubation in patients with ULDO .

NCT ID: NCT06346561 Recruiting - Clinical trials for Nasolacrimal Duct Obstruction

The Efficacy of Dexmedetomidine Versus Labetalol In Providing Controlled Hypotension In Dacryocystorhinostomy SurgeryA Comparative Randomized Prospective Study

Start date: March 30, 2024
Phase: N/A
Study type: Interventional

The most important symptoms of nasolacrimal duct obstruction are excessive tearing and mucoid discharge. The proposed treatment in this regard is dacryocystorhinostomy (DCR) surgery. Therefore, hemostasis is of great significance in performing DCR surgery. In this regard, the reduction of controlled hypotension and the control of hemodynamic responses of the body to stress effectively reduce the bleeding volume during surgery. Hence, there is no enough studies about controlled hypotension in DCR we decided to perform such a comparison between the effect of dexmedetomidine and labetalol in providing controlled hypotension during DCR surgery.

NCT ID: NCT06226181 Recruiting - Clinical trials for Nasolacrimal Duct Obstruction

Amniotic Membrane for Dacryocystorhinostomy

AMDCRex
Start date: January 1, 2024
Phase: Phase 1
Study type: Interventional

This study aims to compare the success rate of external dacryocystorhinostomy with and without amniotic membranes in patients with nasolacrimal duct obstruction.

NCT ID: NCT05999630 Recruiting - Thyroid Cancer Clinical Trials

Artificial Tears to Prevent Nasolacrimal Duct Obstruction in Patients Treated With Radioactive Iodine for Thyroid Cancer

Start date: August 21, 2023
Phase: Phase 3
Study type: Interventional

The association of radioiodine therapy for the treatment of thyroid cancer with nasolacrimal duct obstruction has been well documented in the medical literature. Prior case reports have documented radioactive iodine detection in the tears of patients following radioiodine therapy. It is possible that radioactive uptake by the cells in the lacrimal sac and nasolacrimal duct lead to inflammation, fibrosis, and obstruction of the tear duct over time. A recent study has shown that the administration of artificial tears decreases the level of detectable radioiodine in the tears of patients undergoing radioiodine therapy for thyroid cancer. The purpose of this study will be to assess whether administering tears after radioactive iodine therapy for thyroid cancer decreases the incidence of nasolacrimal duct obstruction in the two years following radioactive iodine treatment.

NCT ID: NCT05999058 Completed - Clinical trials for Lacrimal Duct Obstruction

Clinical Study of Lacrimal Drainage Obstruction Diseases Using Dacryoendoscopy

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

Nasolacrimal duct obstruction (NLDO) can manifest as epiphora or recurrent infections with mucopurulent discharge and may even cause social embarrassment. Dacryoendoscopic-assisted laser dacryoplasty with silicone intubation (DLDI) offers direct therapy to the obstructed site, leading to minimal collateral damage external to the target zone. Although the silicone intubation using dacryoendoscopy has increased the success rates, the success rates vary from a low of 51% to a high of 90%. The difference in success rates seems to depend on the site of obstruction, differences in the surgical technique, stringency of definitions of success, and duration of follow-up. The aim of our study was to report the results of DLDI for the management of NLDO, and to identify factors associated with DLDI failure.

NCT ID: NCT05241054 Not yet recruiting - Clinical trials for Patient With Nasolacrimal Duct Obstruction

Effect of Local Anesthesia Versus Induced Hypotensive Anesthesia on Quality of External Dacryocystorhinostomy Operation

Start date: March 2022
Phase: N/A
Study type: Interventional

Bleeding is one of the important complications during Dacryocystorhinostomy, which dissatisfy ophthalmic surgeon, reduces surgical field visualization, and increases the duration of surgery Thus, the management of this complication is a great consideration during this operation. The aim of this study is to compare the efficacy of combined local and general anesthesia in a group of patients undergoing external dacryocystorhinostomy (DCR) operation versus the efficacy of general anesthesia with induced hypotensive anesthesia

NCT ID: NCT04943055 Recruiting - Clinical trials for Lacrimal Duct Obstruction

Start date: October 10, 2018
Phase: N/A
Study type: Interventional

To compare the clinical effects of low temperature plasma ablation combined with lacrimal duct catheterization and YAG lacrimal duct laser combined with lacrimal duct catheterization in the treatment of lacrimal duct obstruction
