Iris recognition is one of the most robust human identification methods. In order to carry out accurate iris recognition, many factors of image quality should be born in mind. The eyelid occlusion is a quality factor that may significantly affect the accuracy. In this paper we introduce a new fuzzy multi-objective optimization approach based on the eyelid detection method. This method obtains t...

A 33-year old Korean man visited our department complaining of single mildly pruritic yellowish flat-topped papule on left upper eyelid. Lipid profile including low density lipoprotein-cholesterol and triglyceride level was above normal range. He remembered that the site was scalded by boiling oil about eight months ago. The patient was diagnosed with xanthelasma palpebrarum (XP) based on the c...

PURPOSE We investigated the incidence of prostaglandin-associated periorbitopathy (PAP) in subjects with glaucoma treated with latanoprost ophthalmic solution. SUBJECTS AND METHODS One eye and the forehead in 22 subjects were evaluated. All patients had used latanoprost for more than 1 year (range, 12 to 45 months; mean, 26.0 months) and were prostaglandin F2α analogue treatment-naïve. Digita...

PURPOSE To review the recent data about eyelid morphogenesis, and outline a timeline for eyelid development from the very early stages during embryonic life till final maturation of the eyelid late in fetal life. METHODS The authors extensively review major studies detailing human embryologic and fetal eyelid morphogenesis. These studies span almost a century and include some more recent cada...

Eyelid lacerations are common in horses and should be regarded as surgical emergencies to prevent undesirable tissue devitalization, infection, scarring, corneal desiccation, and corneal ulceration. Lacerations usually can be repaired in the standing, heavily sedated horse. General anesthesia may be required when there is extensive trauma or with an unruly horse. Even when horses are not evalua...

Patients with facial paralysis may develop ophthalmic complications. Poor eyelid closure and lagophthalmos place the patient at increased risk for the development of corneal problems such as epithelial defects, stromal thinning, bacterial infection, and even perforation. Initial treatment should be conservative and include the use of ocular lubricants, moisture chambers, and taping of the lower...

PURPOSE Embryonic eyelid closure is a well-documented morphogenetic episode in mammalian eye development. Detection of eyelid closure defect in humans is a major challenge because eyelid closure and reopen occur entirely in utero. As a consequence, congenital eye defects that are associated with failure of embryonic eyelid closure remain unknown. To fill the gap, we developed a mouse model of d...

Transcutaneous lower blepharoplasty addresses excess skin, muscle, and fat through an infraciliary cutaneous incision. This approach offers excellent exposure to the fat pads; however, violation of the orbital septum may result in postoperative lower eyelid retraction, with resultant aesthetic disfigurement as well as exposure keratoconjunctivitis.1 The transconjunctival approach to lower bleph...

OBJECTIVE We describe the case of a patient with metastatic breast cancer who presented with eyelid margin thickening and madarosis more suggestive of sebaceous cell carcinoma than metastatic disease. Histopathology confirmed metastatic breast adenocarcinoma. CASE REPORT A 59-year-old woman with a known history of metastatic breast carcinoma actively enrolled in a clinical trial presented wit...

PURPOSE To report the frequency and relationship of eyelid retraction, lid lag, lagophthalmos, and von Graefe's sign in a group of patients with Graves' ophthalmopathy and compare these findings to those in a group of normal individuals. DESIGN Retrospective comparative cohort study. PARTICIPANTS Fifty consecutive Graves' ophthalmopathy patients were compared to a control group of 50 normal...
