Filter by:This study tests a new treatment to help with droopy eyelids (ptosis) and eye movement problems (squint) in children and young people with genetically confirmed mitochondrial conditions - using red-light. We use a torch to shine a red light through the closed eyelid for 3 minutes a day. The study will run for 18 months. We believe that this treatment could help strengthen the muscle in the eyelid to make it easier to open the eyes, and could also help some children with squint.
An objective assessment of that part of the spectrum of ophthalmic eyelid surgeries that focuses on correcting the position of entropy (e.g. ectropion, ptosis surgery) is very difficult - although it is possible to use different measuring parameters (distance of pupillary reflexes from the edges of the eyelid), comparing different distances on the face, exophthalmometry or the lid laxity test - the so-called snap-back test, but all these methods are based either on the subjective assessment of the examiner or on the correctness of the attached ruler, and their objectivity is therefore very low.
This research study aims to compare whether Phenylephrine 2.5% ophthalmic eye drop solution can serve as a better indicator of the effect of a drooping upper eyelid (ptosis) by covering part of the upper portion of the field of vision as compared to traditional use of tape to lift up the upper eyelid in the evaluation of patients for surgical upper eyelid repair.
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.
The purpose of this study is to observe and report the effects of topical ophthalmic brimonidine in oculofacial plastic surgery.
Prospective clincal study to relate the structure of Whitnall ligament in cases of congenital ptosis to the severety of ptosis and the postoperative results.
To develop a real-time magnetic device prototype for temporary management of blepharoptosis and evaluate its efficacy and safety, including the gain of palpebral fissure height, visual axis obstruction, blurred vision, foreign body sensation over the cornea, burning or hot sensation over facial skin, and erythema or pruritus over the eyelid, by performing a human trial on patients with unilateral blepharoptosis.
This study is being conducted to determine whether the use of bandage contact lens after ptosis surgery provides any benefits for the patient or is unnecessary.
Blepharoptosis (ptosis) repair is a common and generally well tolerated surgical procedure usually performed using local anesthetic. However, a subset of patients appears to experience intraoperative pain/discomfort during ptosis repair using an anterior approach with subcutaneous local anesthetic. Posterior subconjuctival local anesthetic is currently used for eyelid procedures such as chalazion incision and drainage and full-thickness eyelid resections. The purpose of this study is to determine whether an additional subconjunctival injection of local anesthetic, through the posterior aspect of the eyelid, reduces intraoperative pain during anterior ptosis repair.
Blepharoptosis, inferodisplacement of the upper eyelid, can be congenital or acquired. Acquired Blepharoptosis is usually aponeurotic, due to stretching or disinsertion of the levator aponeurosis. Treatment is surgical and can be performed by three common procedures - Levator advancement, Müller's muscle-conjunctival resection procedure and White line advancement. A number of reports inspected the possibility that Blepharoptosis repair procedures may cause deterioration in dry eye status. The investigators would like to assess whether there is a difference between the different procedures in their influence on dry eye status.
