Favre-Racouchot Disease of the Periocular Region.

Abstract: This study details the case of periocular Favre-Racouchot disease an often underdiagnosed entity with a complex differential diagnosis. This is an unusual condition that can potentially affect the periocular region; however, there is little information regarding Favre-Racouchot disease reported in the peer-reviewed ophthalmology literature. Increased awareness of Favre-Racouchot disease among ophthalmologists, oculofacial surgeons, and other specialists can lead to proper diagnosis impacting treatment options and patient outcome.

Predicting outcomes following second intent healing of periocular surgical defects

Abstract: Traditionally, second intent healing (SIH) in the periocular region is reserved for small and/or concave defects, particularly those located on the medial canthus. The purpose of this study was to identify factors impacting outcomes of SIH for periocular tumors following Mohs micrographic surgery (MMS). Retrospective analysis was performed of all periocular lesions treated with MMS followed by SIH from a single academic surgical center over a 5-year period. Data regarding tumor characteristics and follow-up was recorded. The modified Manchester scale was utilized to evaluate scar outcomes. Of the 39 tumors included, 14 (35.9%) were located on the lower eyelid, 12 (30.8%) on the upper eyelid, 6 (15.4%) on the lateral canthus, and 7 (17.9%) on the medial canthus. Involvement of the eyelid margin was seen in 11 (28.2%) of cases. The average defect diameter and area were 1.3 cm and 1.04 cm-squared. Twenty-three cases (59.0%) healed with optimal results. Larger defects were significantly associated with poorer outcomes of SIH (odds ratio 0.205, p = 0.017 by multivariate analysis). Anatomic location, involvement of the lid margin, age, and follow-up interval were not significant factors; however, medial canthus defects were least likely to heal with optimal results. On average, medial canthal lesions were larger in size (mean diameter 1.76 cm, mean area 1.97 cm-squared). This retrospective study suggests that periorbital defects in all locations with area less than 1.04 cm2 heal well by SIH. In this cohort, larger lesions on the medial canthus healed with worse outcomes.

Reconstructive Methods on Different Parts of the Periocular Region after Mohs Micrographic Surgery in a Combination of Dermatologist and Facial Plastic Surgeon Practice

Abstract: Objective: In the United States, the majority of post-Mohs closures around the eye are done by Mohs surgeons, who are mainly dermatologists. The objective of this study is to determine the options for closing post-Mohs defects on different parts of the periocular region that is performed by both a Mohs surgeon and facial plastic surgeon as a team. Non-melanoma skin cancer is common around the eyes and can lead to great morbidity. Mohs micrographic surgery is the treatment of choice for its resection. The resulting wound can be extensive, and the reconstruction can have great ramifications on both eyelid function, visual acuity, and esthetics. The majority of the reconstruction is handled by the Mohs surgeons. Methods: We presented 28 periocular Mohs closures that were done at a practice where a combined Mohs surgeon and facial plastic surgeon operated together in a team as opposed to individually. Results: We find that this combination provided more complex closures such as flaps and grafts, while previous publications had shown that Mohs surgeons more often close with a primary closure. Different regions of the periocular region were examined for treatment methods. The medial canthus was most often affected, and advancement flaps were most commonly used followed by full-thickness skin grafts. We did not have any cases on the upper eyelid, highlighting the sun protected characteristic of the anatomy. Conclusion: This is the first publication presenting a large number of post-Mohs closures that were reconstructed by a combined Mohs surgeon and facial plastic surgeon. The significance is that the combined skills of a Mohs surgeon and facial plastic surgeon offer a wider range of closure techniques, to the benefit of the patient.

Periocular Region-Based Biometric Identification Using Local Binary Pattern and Its Variants

Abstract: Biometric systems are gaining importance significantly in the present day automated systems especially in the areas of authentication, access control, security, and forensic applications for the identification of criminals. Existing biometric systems using the face and iris regions had reached the state of maturity with almost having high performances of 100% accuracy provided the images of the subjects are acquired in the cooperative scenarios. The periocular region is one of the most promising biometric traits providing better robustness and high discrimination ability. Periocular region-based biometric recognition systems are well suited for the wild environments where the subjects are not cooperative. In the proposed paper, the pixel-based LBP and patch-based LBP variants are used as local descriptors for the feature extraction of discriminative features from the full face and periocular regions. Euclidean distance is used to find the matching score between two extracted feature vectors. The experimentation is performed on FRGC, FERET, and Georgia Tech face databases to compare the performance of both periocular and face biometric modalities. It showed that the periocular region has almost the same level of performance of the face region using only 25% data of the complete face.
