Filter by: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
To demonstrate that DMSt + RF improves eye blink quality in subjects with dry eye disease
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.
This study investigates the effect of tranexamic acid, a medication that helps reduce bleeding, in patients undergoing surgeries around their eyes.
Medial upper eyelid pad of fat bulge is a common problem. medial fat pad preservation might be a good adjutant to upper eyelid blepharoplasty
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.
eyelid lesion excision is a common eyelid procedure. It associated with visual, aesthetic and functional changes .Investigator will evaluate patient satisfaction.
Brow ptosis is a common problem. internal browbexy and brassier suture are common surgical approach
lower eyelid involutional entropion and dermatochalasis are common associated problems. combined approaches give good results.
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 .
