NCT04898933
Puncto-canalicular abnormalities, such as obstruction and canaliculitis, are a significant cause of epiphora. They involve proximal lacrimal drainage system. Proximal lacrimal obstructions classified into punctal stenosis canalicular obstructions. The basic principles in the treatment of punctal stenosis include creating an adequate opening, while maintaining the position of the punctum against the lacrimal lake, and preserving the lacrimal pump function. The severity of epiphora can be valued trough a grading system such as the Munk scale, fluorescein dye disappearance test, and syringing and probing and contrast dacryocystography. Canaliculitis is defined as infection of the proximal part of the lacrimal drainage system. This condition can be caused by primary infectious organisms or secondary to punctal plugs and lacrimal stents. Diagnosing canaliculitis is frequently misdiagnosed. The management includes conservative measures, local massage, syringing, and irrigation. Nevertheless, refractory cases required surgical intervention.

The purpose is to investigate the diagnostic value (sensitivity and specificity) of dermal-Optical Coherence Tomography (D-OCT, VivoSight Dx), in patients with clinically suspected BCC lesions inside the periocular region and compare these results to previous reports using D-OCT in diagnosing lesions outside the periocular area. The Hypotheses: * The sensitivity and specificity of D-OCT in diagnosing BCC inside the periocular region is comparable to previous reports on BCC lesions outside the periocular region when the standard D-OCT probe is used. * The sensitivity and specificity of D-OCT in diagnosing BCC inside the periocular region is increased when the customised D-OCT probe is used. * The sensitivity and specificity of D-OCT in diagnosing periocular BCC is comparable to punch biopsy when both standard and the customised D-OCT probes are used. * D-OCT with the 10 and 20-millimeter standoff is capable of subtyping periocular BCC. * The inter-observer variation in diagnosing and sub-typing periocular BCC decreases with increasing experience in the scanning procedure. * The number of scans to correctly interpret D-OCT decreases with increasing experience in the scanning procedure. * Delineation of periocular BCC tumour extension is possible using both D-OCT probes
NCT05750251
The goal of this prospective observational study is to learn about the impact of conventional eyelid correction surgery on the eye's health and function in ptosis and eyelid retraction patient. The main questions it aims to answer are: • 1. Changes in corneal topography, higher-order corneal aberrations, corneal biomechanical characteristics, and corneal epithelial thickness before and after the surgery 2. Influence of corneal refraction examinations , vision change, and tear film function after the surgery Fifty participants will undergo conventional eyelid correction surgery by the same ophthalmologist (YH Wei) and non-invasive examinations before and after the surgery. The patient will be separate to 2 groups, including 30 with correction for ptosis and 20 with correction for eyelid retraction. The research will collect information of the operated eye and fellow eye, and the data will be compared between operated and fellow eye and with the other group.
NCT05672407
This study investigates the effect of tranexamic acid, a medication that helps reduce bleeding, in patients undergoing surgeries around their eyes.
NCT05016362
Medial upper eyelid pad of fat bulge is a common problem. medial fat pad preservation might be a good adjutant to upper eyelid blepharoplasty
NCT04201925
Upper blepharoplasty is a common eyelid procedure. It associated with visual, cosmetic and functional changes .Investigator will evaluate outcome of this procedure.
NCT04689230
Medial upper eyelid pad of fat bulge is a common problem. Small incision surgery could be a time-efficient, minimally invasive and scar formation procedure .
NCT01086943
The eyelid warming device is designed to relieve the symptoms of dysfunction of the glands in the eyelids. Prospective, non comparative, open, monocentre study. The objectives are: * To verify and establish the temperature of the eyelids and cornea for each eye before and after 10 minutes device application * To evaluate the ocular surface, NIBUT and IOP before and after device application * To determine the acceptability of healthy volunteers on the practical use of this device The subjects will attend 2 visits.
NCT01091311
Multicentric study, open label, uncontrolled phase IV in 30 patients with meibomian glands dysfunction . Its objective is to Collect information from patients and ophthalmologists specialized in ocular surface and eyelids to anticipate how Blephasteam ® can be optimized. This study involves 2 visits, visit of Inclusion, J0, then end of study visit, D21. Between the two visits patients will be treated with Blephasteam ® for 21 days (up to two uses per day) and complete a questionnaire every two days during the first week and then once a week the next two weeks.
NCT01190397
The eyelid warming device is designed to relieve the symptoms of dysfunction of the glands in the eyelids Phase I, prospective, comparative study, investigator masked , monocentric Objectives are To assess and compare the warming and moisture of Blephasteam® device versus the warming and moisture of warm and moist compresses. To assess and compare safety on the ocular surface after 10 minutes of Blephasteam® application versus after 10 minutes of warm and moist compresses application
