Face recognition performance degrades significantly under occlusions that occur intentionally or unintentionally due to head gear or hair style. In many incidents captured by surveillance videos, the offenders cover their faces leaving only the periocular region visible. We present an extensive study on periocular region based person identification in video. While, previous techniques have hand...

The periocular region is the part of the face immediately surrounding the eye, and researchers have recently begun to investigate how to use the periocular region for recognition. Understanding how humans recognize faces helped computer vision researchers develop algorithms for face recognition. Likewise, understanding how humans analyze periocular images could benefit researchers developing al...

The upper and lower eyelids are traditionally contraindicated for subcutaneous botulinum toxin A (BTX) injection because of possible complications. We assessed the clinical safety and effectiveness of nonablative fractional laser (NAFL) combined with transdermal delivery of BTX in the treatment of periocular wrinkles. Thirty patients who had periocular wrinkles were treated with 1,565-nm NAFL i...

OBJECTIVE To evaluate the efficacy and tolerance of a novel line treatment for periocular and perioral wrinkles. The line treatment was formulated with multiple growth factors, antioxidants, and a collagen-building peptide-ingredients that have been shown to increase collagen levels and provide long-term aesthetic benefits. To help provide immediate smoothing effects, hyaluronic acid filling sp...

OBJECTIVE To review the effectiveness and toxicity of periocular topotecan hydrochloride in fibrin sealant (Tisseel) for the control of intraocular retinoblastoma. METHODS Retrospective medical record review of visually threatening or recurrent intraocular retinoblastoma treated with periocular topotecan. RESULTS Eight children (10 eyes) received 1 to 4 injections of periocular topotecan in...

BACKGROUND Advanced carcinoma of the head represents a substantial health problem in cats for local control and overall survival. OBJECTIVES Evaluate the capability of electrochemotherapy (ECT) to improve bleomycin efficacy in cats with periocular carcinoma and advanced carcinoma of the head. ANIMALS Twenty-one cats with periocular carcinoma (17 squamous cell carcinoma [SCC] and 4 anaplasti...

PURPOSE In this study, we investigated the penetration of various proteins into the mouse eye after a periocular injection of the protein or an adenoviral vector (Ad) expressing the protein. METHODS At several time points after the injection, the retina, retinal pigmented epithelium/choroid, and sclera were dissected and enzyme-linked immunosorbent assays were performed. RESULTS After a per...

purpose : to review periocular dermoid cysts to determine distribution of demographic factors, and tumor location methods : in this retrospective, observational case series in a tertiary-care hospital, we reviewed all cases of histopathologically verified periocular dermoid cysts at our institution between 2003 and 2011. the study endpoints included: age, gender, and tumor location. results : t...
