Filter by:The aim of this study was to compare the outcome of levator muscle resection with plication in mild to moderate congenital unilateral blepharoptosis.
This study is looking at the effect of Tisseel in eyelid surgery. Fibrin sealants (Tisseel) cause there to be less bleeding during surgery. Surgeons have used Tisseel for over two decades to reduce bruising. Ophthalmologists use it during surgery. Yet, there are no studies confirming the effect of Tisseel during eyelid surgery. Unpublished work suggests that it is effective in decreasing postoperative bruising. This study will confirm the effect of Tisseel on postoperative bruising in blepharoplasty.
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.
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.
The aim of the study: Assessment of Changes of Periocular Skin Sensation Following Eyelid and Ocular Surface Surgeries. Study design: an interventional study that will be conducted at the ophthalmology department, Meir hospital, Kfar Saba, Israel. the study will include 60 healthy patients, at the ages of 40-80, which are candidates for eyelid surgery: blepharoptosis repair, blepharoplasty, ectropion repair and entropion repair. The patients will be recruited from Meir's ophthalmology outpatient clinic. Each patient will undergo a full ophthalmologic examination including relevant assessment of the specific eyelid pathology. The eyelid's sensation will be assessed at 6 points of the eyelid using the Cochet-Bonnet filament-type aesthesiometer (Luneau Ophtalmologie, Paris, France). Measurements will take place before surgery, and two weeks, three months and six months after surgery.
