This paper proposes a computationally efficient eyelid detection algorithm for detecting eyelid boundaries in iris images acquired under less constrained imaging conditions. The proposed eyelid detection algorithm is developed based on the live-wire technique. The major advantage of the proposed algorithm is its computational simplicity as compared to the prior eyelid detection algorithms. The ...

Deficient eyelid closure is a major visual threat to patients with unresolved facial nerve palsy. Gold weight implants assisted eyelid closure in patients with paresis of the orbicularis oculi, ameliorating patient complaints of dry eye, excessive tearing, and corneal epithelial breakdown. We used dynamic measures to assess the efficacy of upper eyelid gold weight implantation surgery for facia...

A 67-year-old male had suffered from eye movement disturbance from Graves’ orbitopathy. His right eye was fixed in an esotropic position. Examination by synoptophore showed that his right eye deviation was 22 degrees medially. The upper eyelid margin reflex distance (MRD) was 3.5 mm OD and 5.6 mm OS, and the lower eyelid MRD was 5.1 mm OU. Six mm medial rectus muscle recession with tenotomy was...

Purpose Tissue closure/fusion is a fundamental process during organogenesis, driven in part by the Wnt/planar cell polarity (Wnt/PCP) pathway. This study explored the spatial and temporal aspects of PCP signaling in eyelid development through analysis of mice lacking Prickle 1, a core PCP component, and the Prickle1-dependent signaling networks underlying eyelid development. Methods Wild type...

PURPOSE One of the most common problems of the surgical management of Graves upper eyelid retraction is the occurrence of eyelid contour abnormalities. In the present study, the postoperative contour of a large sample of eyelids of patients with Graves orbitopathy was measured. METHODS The postoperative upper eyelid contour of 62 eyes of 43 patients with Graves orbitopathy was subjectively cl...

Melanomas are common in grey horses and rare in other colors of horse. They usually present as nodules in the eyelid and often involve the eyelid margin. They rarely ulcerate and are most often of a benign slow growing nature [2,3]. They are most often benign in the horses [4] and dog [5], but frequently malignant in the cat [6]. If the eyelid mass involves less than about one third of the eyel...

PURPOSE Too investigate asymmetry in eyelid movements with blinking, the stability of the asymmetry, and its modifiability in normal humans. METHODS Differences in the start time and amplitude between the two eyelids were assessed for voluntary blinks and reflex blinks evoked by supraorbital trigeminal nerve stimulation. These variables were also measured before and up to 18 months after 2 ho...

PURPOSE To report a new technique in the repair of lower eyelid malposition using dermis fat as a posterior lamellar spacer graft. DESIGN Retrospective, consecutive, nonrandomized interventional case series. PARTICIPANTS Eleven patients who underwent surgical correction for symptomatic lower eyelid malposition using dermis fat as a spacer graft. METHODS Patients with symptomatic lower eye...

OBJECTIVE To determine the relative frequencies, average annual incidences, and patient characteristics of non-basal cell and non-squamous cell malignant neoplasms of the eyelid in a defined geographic population. DESIGN AND SETTING A retrospective study using the Florida Cancer Data System to identify malignant tumors of the eyelid, except for basal cell and squamous cell carcinomas, from 19...
