TL;DR: It is concluded that the CNN is sensitive to changes in the facial expressions and samples of all expressions are required for training aiming the best accuracy.
Abstract: The biometric periocular trait refers to the face region in the vicinity of the eye, including the eyelids, eyelashes and eyebrows. The periocular region has emerged as a promising trait for unconstrained biometrics, due to recent advances of convolutional neural networks and the demand for robust face or iris recognition systems. The periocular region can offer global information about the eye shape, and about the texture of the iris, sclera and skin around the eyes. However, periocular biometrics is a relatively new area of research. Thus, it's important to understand the uniqueness and stability of this trait, taking into account the best accuracies obtained by deep learning methods applied on biometric image recognition. In this work, we investigate if changes in the periocular region, caused by facial expressions, affect the recognition accuracy. We apply an existing pretrained CNN architecture, called MobileNet, to the task of periocular recognition. The periocular images used in the experiments were extracted from the Extended Cohn-Kanade expression database. The best results were obtained when the network was tested with similar samples to those contained in the training set. We concluded that the CNN is sensitive to changes in the facial expressions and samples of all expressions are required for training aiming the best accuracy.

TL;DR: Submental and anterior neck regions are useful full-thickness skin graft donor sites for eyelids procedures, particularly in elderly females with submental fullness and skin redundancy, and can be considered whenever traditional donor sites are unavailable.
Abstract: Purpose The submental and neck regions share cutaneous features with the face and are suitable donor sites for facial full-thickness skin grafts (FTSGs). Age-related laxity and skin redundancy in the cervicomental region may be an additional motivator to use its skin. We aim to describe, raise awareness, and remind surgeons of the utilization of submental and anterior neck as sources of FTSG for the periocular region, particularly when traditional donor sites are unavailable. Methods Retrospective case series of 5 patients who underwent periocular FTSG from anterior neck and submental regions between January 2017 and January 2019. All patients had contraindications to the usually preferred graft donor sites. Main outcome measures were surgical functional results and cosmesis. Results Five patients (all female) received FTSGs using anterior neck and submental regions as donor sites. Two patients required skin grafts due to eyelid retraction and anterior lamella shortening; one due to previous multiple basal cell carcinoma excisions with FTSG reconstructions and the other due to chronic Bell's palsy. Three patients required skin grafts for Hughes flap reconstruction after excision of lower eyelid basal cell carcinoma. In all patients, conventional skin donor sites were unavailable or unsuitable due to previous skin grafting, actinic changes, postauricular situated hearing aids or patient's preference. All patients achieved good cosmesis and functional results. None of the patients experienced donor site morbidities. Conclusions Submental and anterior neck regions are useful FTSG donor sites for periocular procedures, particularly in elderly female patients with submental fullness and neck skin redundancy.

TL;DR: Ce traitement suppose une bonne connaissance prealable de l’anatomie musculaire fonctionnelle de la face ainsi que du produit utilise de la partie haute du visage.
Abstract: Botulinum toxin injections are first-line treatment for facial lines in the upper part of the face. The relatively easy injection techniques at the forehead, the glabellar region, and the periocular region make this treatment advantageous. This treatment requires good knowledge of the functional anatomy of the face and of the product used. After semeiologic analysis of facial aging, it provides results that respect the natural contours of the face, allowing one to adapt the treatment to each patient's wishes.

TL;DR: Orbital invasion from eyelid tumors usually results from a delayed presentation/diagnosis, incomplete treatment with subsequent recurrences, and highly aggressive invasive tumors.
Abstract: Malignant skin neoplasias commonly affect the eyelids and periocular region, particularly in high UV exposure zones. Secondary orbital invasion is a serious and potentially fatal complication of cutaneous tumors. The most frequent skin tumors resulting in orbital invasion are basal cell carcinoma, squamous cell carcinoma, sebaceous gland carcinoma, and malignant melanomas. Orbital invasion from eyelid tumors usually results from a delayed presentation/diagnosis, incomplete treatment with subsequent recurrences, and highly aggressive invasive tumors.
