Surgical Anatomy of the Ocular Adnexa is a beautifully and thoughtfully illustrated anatomical text that provides the ophthalmic surgeon or any surgeon working in the eyelid/orbital region with detailed yet concise, easy to read and understand descriptions of the anatomy in any particular region of the eyelid, orbit or nasolacrimal system. Throughout the text are clinical pearls and vignettes to help the reader appreciate why certain anatomical features are important to understand. Key anatomical concepts are highlighted and easy to visualize with real cadaver photos as well as the artists rendition of the same region. This book: - Develops a thorough understanding of the anatomy in the eyelid, orbit, nasolacriaml and periocular regions. - Fosters an appreciation of how knowledge of the anatomy leads to a better understanding of the pathophysiology of various disease processes involving the eyelid, orbit, nasolacrimal and periocular region. - Conveys the importance of anatomy in the surgical approach to various disease processes in the eyelid, orbit, nasolacrimal and periocular regions. This second edition will be an invaluable guidel to all those working in the eyelid, orbital, and nasolacrimal areas including residents, fellows and staff in ophthalmology, otolaryngology/head and neck surgery, plastic surgery and neurosurgeons working in and around the orbit.

A novel approach for selecting a rectangular template around periocular region optimally potential for human recognition is proposed. A comparatively larger template of periocular image than the optimal one can be slightly more potent for recognition, but the larger template heavily slows down the biometric system by making feature extraction computationally intensive and increasing the database size. A smaller template, on the contrary, cannot yield desirable recognition though the smaller template performs faster due to low computation for feature extraction. These two contradictory objectives (namely, (a) to minimize the size of periocular template and (b) to maximize the recognition through the template) are aimed to be optimized through the proposed research. This paper proposes four different approaches for dynamic optimal template selection from periocular region. The proposed methods are tested on publicly available unconstrained UBIRISv2 and FERET databases and satisfactory results have been achieved. Thus obtained template can be used for recognition of individuals in an organization and can be generalized to recognize every citizen of a nation.

Abstract Saksenaea erythrospora is a rare pathogen in humans. Ten adult cases have been previously reported, eight manifested with cutaneous infection, and two presented with invasive rhinosinusitis infection. The authors present a 16-month-old boy with progressive painful mass at the right medial canthus and upper cheek that was unresponsive to broad-spectrum antibiotics. He underwent an anterior orbitotomy and biopsy. Histopathology revealed broad nonseptate sterile hyphae and grew S. erythrospora, which was confirmed by molecular techniques. The patient was treated with intravenous liposomal amphotericin B and oral itraconazole combined with aggressive surgical debridement. The patient made a complete recovery without long-term complications at 4 months of follow-up. Primary cutaneous mucormycosis caused by S. erythrospora may rarely involve the periocular region and mimic chronic dacryocystitis. We report the first case of pediatric periocular cutaneous mucormycosis caused by S. erythrospora.
