- Upper eyelid platinum weight placement for the treatment of paralytic lagophthalmos: A new plane between the inner septum and the levator aponeurosis. [Journal Article]
- APArch Plast Surg 2018; 45(3):222-228
- CONCLUSIONS: Postseptal weight placement is a safe and reproducible method in both primary and secondary upper eyelid surgery for patients with paralytic lagophthalmos. It is a feasible method for preventing implant visibility, implant exposure, and entropion. Moreover, platinum is a better implant material than gold because of its smaller size and greater thinness.

Adequate ophthalmic diagnostic and clinical skills are essential for practitioners in primary care settings as well as specialty care physicians. The objectives of this study were to assess the adequacy of ophthalmology teaching in undergraduate medical education and to evaluate the comfort of medical students in diagnosing common eye problems and performing ophthalmic skills.
- Micropunch blepharopeeling versus blepharoplasty; what is the best procedure for upper eyelid rejuvenation? [Journal Article]
- JCJ Cosmet Dermatol 2018 May 17

The management of cicatricial entropion represents a therapeutic challenge especially when the underlying causes are progressive cicatricial diseases that affect the ocular surface. The authors aimed to report long-term efficacy of labial mucous membrane graft to manage severe cicatricial entropion of the upper eyelid. This study is a retrospective chart review of patients who underwent tarsotomy associated with labial mucous membrane graft to treat severe cicatricial entropion of the upper eyelid. Surgeries were performed over a 16-year period. Clinical data (age, gender, etiology of the cicatricial entropion, improvement of symptoms, eyelid position, recurrence, complications, and follow-up period) were extracted from these patients' charts. Etiology of the cicatricial entropion, improvement of symptoms, eyelid position, recurrence, complications, and follow-up period were evaluated. Sixty-three eyelids from 44 patients underwent surgery. Mean follow-up was 48.4 ± 46.1 months (range 6 months to 15 years). Main underlying diagnoses were Stevens-Johnson syndrome (63%), trachoma (19%), chemical injury (8%), and trauma (5%). Forty-three patients (98%) reported improvement of ocular symptoms after the procedure. Complete resolution (restoration of the upper eyelid margin to normal anatomic position with good esthetic appearance) was achieved in 52 eyelids (83%). Recurrence occurred in 7 (11%) eyelids. No postoperative infection, failure of graft survival, or other complications were observed. The use of labial mucous membrane as a posterior lamella graft showed good functional and cosmetic outcomes, long-term stability and low recurrence rates in the treatment of severe cicatricial entropion of the upper eyelid.
- The Effect of Age on the Regenerative Potential of Human Eyelid Adipose-Derived Stem Cells. [Journal Article]

Human eyelid adipose-derived stem cells (HEASCs) are a new source of autologous mesenchymal stem cells, which are derived from neuroectoderm and potentially applied in the tissue regeneration and cell therapies. Based on the prevalence of blepharoplasty in Asia and the availability of HEASCs, we investigated the effect of donor age on their characteristics and regenerative potential of HEASCs in vitro. The HEASCs were isolated from patients of three groups: (1) <20 years (n = 4), (2) >20 years, <45 years (n = 5), and (3) >55 years (n = 4). For each group, the proliferative capacity, colony-forming ability, surface markers, differentiation ability, wound healing function, and secreted protein were contrastively evaluated and quantified for statistical analysis. It was found that HEASCs were successfully isolated and cultured by an explant culture method. The proliferative rates, osteogenic and chondrogenic differentiation potentials, wound healing ability, and the expression of TGF-β1 and fibronectin protein of HEASCs significantly decreased as age increased. However, the expression of CD90 antigen and the adipogenic differentiation showed an age-related increase in HEASCs. As many degenerative diseases increase in prevalence with age, the age-related changes of the HEASCs proliferation potential, differentiation capacity, and wound healing ability should be taken into account whenever they are intended for use in research or cytotherapy.

The evaluation of eye blinking has been used for the diagnosis of neurological disorders and fatigue. Despite the extensive literature, no objective method has been found to analyze its kinematic and dynamic behavior. A non-contact technique based on the high-speed recording of the light reflected by the eyelid in the blinking process and the off-line processing of the sequence is presented. It allows for objectively determining the start and end of a blink, besides obtaining different physical magnitudes: position, speed, eyelid acceleration as well as the power, work and mechanical impulse developed by the muscles involved in the physiological process. The parameters derived from these magnitudes provide a unique set of features that can be used to biometric authentication. This possibility has been tested with a limited number of subjects with a correct identification rate of up to 99.7%, thus showing the potential application of the method.

- Classification of Trigeminal Autonomic Cephalalgia: What has Changed in International Classification of Headache Disorders-3 Beta? [Review]

The term "Trigeminal Autonomic Cephalalgia (TAC)" was first coined by Goadsby and Lipton to include a group of relatively rare primary headache disorders characterized by moderate to severe, short-lived head pain in the trigeminal distribution with unilateral cranial parasympathetic autonomic features, such as lacrimation, rhinorrhea, conjunctival injection, eyelid edema, and ptosis. In the current International Classification of Headache Disorders (ICHD-3 beta), the TAC group includes cluster headache (CH), paroxysmal hemicrania (PH), short-lasting unilateral neuralgiform headache attacks (SUNHAs) and their 2 subforms - SUNHAs with conjunctival injection and tearing (SUNCT), SUNHAs with cranial autonomic symptoms (SUNA). Hemicrania Continua (HC) is also now included in the TAC group. Although the entities included under TACs seem broadly similar, they differ in attack duration, frequency and their response to different treatments. At one end of the spectrum lies CH, the prototypic TAC where the duration of attacks is the longest and at the other end is the SUNCT syndrome where the duration is shortest. There is some overlap across the entities; they are not difficult to recognize and subclassify. The umbrella term "TAC" for the short-lasting headaches with autonomic features was for the first time introduced in The ICHD, 2nd edition (ICHD-2) published in 2004. The beta version of the 3rd edition of The ICHD was published in 2013. Headache classification being an evolving process, there have been some changes within the TAC group between ICHD-2 and ICHD-3 beta. Diagnostic criteria have been revised to reflect pathophysiological and clinical observations. Neuroimaging has provided insights into the pathophysiology of TACs. Functional neuroimaging has helped to elucidate key structures activated during attacks of TACs. Correct diagnosis remains the key to correct management of the TACs because treatment options vary. The aim of this article will be to highlight the changes in ICHD-3 beta to this group and to emphasize the clinical implications of these changes. Description of individual entities included under TACs are included elsewhere and will therefore not be detailed here.

- Bovine Acellular Dermal Matrix for Levator Lengthening in Thyroid-Related Upper-Eyelid Retraction. [Journal Article]
- MSMed Sci Monit 2018 May 02; 24:2728-2734
- CONCLUSIONS: A modified levator-lengthening procedure using bovine acellular dermal matrix as a spacer graft ameliorated both the symptoms and signs of severe upper-eyelid retraction secondary to TED. This procedure is a reasonable alternative for correction of TED-related severe upper-eyelid retraction.
