Filter by:The investigators propose utilizing a simple telemedical protocol to allow patients to substitute the first post-operative visit with a remote survey that includes essential post-operative history, vision measurement, and photographs, all of which can be provided using a personal computer, tablet, or smart phone. The investigators have selected for this purpose a subset of oculoplastic procedures involving the eyelid and lacrimal system that have well-reported low rates of serious complications, since high-risk procedures will likely always require close, in-person care. The investigators hypothesize that telemedicine follow-up for the first post-operative week after low-risk oculoplastic surgery will decrease the time burden on patients without compromising their satisfaction or increase the risk of late post-operative complications.
Frontalis sling surgery was carried out using Ptose-up under general anaesthesia for patients with severe congenital ptosis.
Main research purposes of this research is to compare the therapeutic effect and safety of the superior levator muscle shortening combined with the tarsus resection and the traditional frontal muscle flap in the correction of severe ptosis. Aside of above we also tend to explore the dose-effect relationship between the amount of levator muscle shortened/ tarsus resection and postoperative ptosis correction amount.So as to develop a more critical and specific guidelines for clinical treatment of ptosis. So during the research we will recruiting patients with severe ptosis and randomly divide them into levator muscle and tarsus group and frontal muscle flap group, and follow up those patient 6 months post operation so as to evaluate the amount of correction and the side-symptoms.
Blepharoptosis (incomplete opening of the eyelids) occurs because of a disruption in the normal agonist-antagonist neuro-muscular complex balance. An external device could restore eyelid movement. A newer class of permanent magnets made of alloys of neodymium (Nd), iron (Fe) and boron (B) might provide the technology needed to develop a feasible external magnetic device that could restore eyelid movement.
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.
The purpose of the research is to see if Lumify™ has an effect on eyelid position.
Phase 3 study to evaluate the safety and efficacy of treatment with RVL-1201 compared to placebo for treatment of blepharoptosis. Eligible subjects will be randomized to one of 2 treatment arms.
Phase 3 study to evaluate the extended safety of RVL-1201 compared to placebo for treatment of blepharoptosis. Eligible subjects will be randomized to one of 2 treatment arms.
Objectives: Upper eyelid retraction was believed to be maintained solely by voluntary contraction of the levator palpebrae superioris (LPS) and frontalis muscles, together with involuntary contraction of the sympathetically innervated Müller's muscle (MM). However, several studies have suggested that the LPS also undergoes involuntary contractions, and that a visual stimulus may not be the only trigger for frontalis muscle contractions. Recent studies hypothesized that the MM contains proprioceptive neuronal structures, which elicit involuntary LPS muscle contraction by the mesencephalic trigeminal nucleus via a continuous stretch reflex. We aim to identify proprioceptive structures in MM by means of histological examinations. Methodology: Prospective study. Collaboration of oculoplastics, ophthalmologists and a neuroanatomy specialist in Sheba Medical Center. 50 fresh MM specimens from patients undergoing Müllerectomies will undergo histologic examinations, including immunohistochemical staining and light and electron microscopy. Significance: Identification of proprioceptive structures in MM will be the first evidence-based proof of a proprioceptive mechanism in the eyelid. This might have a significant impact on future surgical management of eyelid procedures. Comprehensive understanding of the mechanisms underlying eyelid function is especially important in the management of children with ptosis who may have coexisting amblyopia.
Fibrin glue is widely used in ophthalmology for homeostasis and tissue recovery. It is commonly used in ocular surface surgeries such as pterygium removal and conjunctival lesions excisions. In Müller's muscle-conjunctival resection (MMCR), sutures are used to reconnect the conjunctiva and Muller muscle, which causes discomfort and pain for the patient. The investigators' goal is to explore using fibrin glue instead of sutures in MMCR surgeries to shorten the procedure's length and alleviate patients discomfort and pain. This is especially important in the management of children suffering ptosis, where sedation and even general anaesthesia is required for sutured removal as a secondary procedure.
