NCT ID: NCT06279143 Recruiting - Skin Diseases Clinical Trials

The Diagnostic Accuracy of Advanced Imaging in Identifying Suspected Skin Cancer (Basal Cell Carcinoma) Around the Eyes

dOCT-pBCC
Start date: April 4, 2024
Phase:
Study type: Observational

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

NCT ID: NCT05945069 Recruiting - Dry Eye Clinical Trials

Feasibility of Dynamic Muscle Stimulation + Radiofrequency for Improving Blink Quality in Subjects With Dry Eye Disease

Start date: August 1, 2023
Phase: N/A
Study type: Interventional

To demonstrate that DMSt + RF improves eye blink quality in subjects with dry eye disease

NCT ID: NCT05750251 Recruiting - Eyelid Diseases Clinical Trials

Effect of Upper Eyelid Surgeries on Corneal Characteristics

Start date: February 6, 2023
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT05016362 Recruiting - Eyelid Diseases Clinical Trials

Medial Fat Pad Preservation in Upper Eyelid Blepharoplasty

Start date: December 24, 2020
Phase:
Study type: Observational

Medial upper eyelid pad of fat bulge is a common problem. medial fat pad preservation might be a good adjutant to upper eyelid blepharoplasty

NCT ID: NCT04921020 Recruiting - Eyelid Diseases Clinical Trials

Assessment of Eyelid Topology and Kinetics Based on Deep Learning Method

Start date: August 1, 2020
Phase:
Study type: Observational

This study plans to assess eyelid topology (such as margin reflex distance, eyelid contour, and corneal exposure area) and blinking (such as frequency, velocity, and duration), using deep learning method to automatically extract eyelid topological features, and to predict subtypes of levator function, using deep learning method to extract blinking features, in order to provide new ideas and means to assess eyelid topology and kinetics.

Patient Satisfaction After Eyelid Lesion Excision

Start date: January 20, 2020
Phase:
Study type: Observational

eyelid lesion excision is a common eyelid procedure. It associated with visual, aesthetic and functional changes .Investigator will evaluate patient satisfaction.

Start date: January 10, 2021
Phase:
Study type: Observational

Brow ptosis is a common problem. internal browbexy and brassier suture are common surgical approach

NCT ID: NCT04720586 Recruiting - Eyelid Diseases Clinical Trials

Surgical Treatment of Lower Eyelid Involutional Entropion and Dermatochalasis

Start date: August 1, 2020
Phase: N/A

lower eyelid involutional entropion and dermatochalasis are common associated problems. combined approaches give good results.

NCT ID: NCT04689230 Recruiting - Eyelid Diseases Clinical Trials

Small Incision Technique Versus Upper Blepharoplasty in Upper Eyelid Medial Pad Fat Removal

Start date: October 1, 2020
Phase: N/A
Study type: Interventional

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 .

NCT ID: NCT04359979 Recruiting - Thyroid Eye Disease Clinical Trials

Tamsulosin for Thyroid Lid Retraction

Start date: May 1, 2020
Phase: N/A
Study type: Interventional

The purpose of this study is to examine the effect of using Tamsulosin for treatment of eyelid retraction as part of thyroid eye disease. The treatment will be offered to all thyroid patients suffering from eyelid retraction who are treated at the thyroid clinic in Sheba's Ophthalmology department. All patient will receive information about the drug Tamsulosin, the possible side effects, and the alternative treatment options for retraction. Patients recruited will take 0.4mg/day Tamsulosin for 3 months and will have follow-ups at 1 week, 1 month and 3 months to evaluate the retraction status.
