Measurement of Change in Lower Eyelid Position in Patients Undergoing Transcutaneous Skin-Muscle Flap Lower Eyelid Blepharoplasty
'American Medical Association (AMA)', 2016Co-Authors: Sultan Babar, Genther, Dane J., Perkins, Stephen W.Abstract:Importance Transcutaneous lower Eyelid blepharoplasty is a commonly performed procedure with a postoperative risk of Eyelid Malposition. Objective To quantify the change in lower Eyelid position after transcutaneous lower Eyelid blepharoplasty. Design, Setting, and Participants This retrospective medical record review describes patients who underwent transcutaneous blepharoplasty at a private facial plastic surgery practice. Patients with less than 3 months of follow-up, a history of periocular trauma, and concurrent midface lift were excluded. Interventions Bilateral skin-muscle flap lower Eyelid blepharoplasties with possible tarsorrhaphy, canthopexy, or canthoplasty as indicated. Main Outcomes and Measures Lower Eyelid position determined by measurement of preoperative and postoperative pupil to Eyelid and lateral limbus to Eyelid distances. Results Data from 100 consecutive patients (mean age, 56.7 years; 92 female [92.0%]) undergoing bilateral skin-muscle flap lower Eyelid blepharoplasty were analyzed. The mean increase in distance was 0.33 mm (95% CI, 0.24-0.42 mm) from the pupil to the lower Eyelid margin and 0.32 mm (95% CI, 0.23-0.41 mm) from the lateral limbus to the lower Eyelid margin at final follow-up. For both measurements, patients undergoing concurrent canthopexy had a significantly greater change in Eyelid position (P

non surgical treatment for Eyelid retraction in thyroid eye disease ted
British Journal of Ophthalmology, 2018Co-Authors: Ana Beatriz Diniz Grisolia, Suzana Matayoshi, Raymond S Douglas, Ricardo Couso, Cesar A BricenoAbstract:Thyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of Eyelid Malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal.

tangent screen perimetry in the evaluation of visual field defects associated with ptosis and dermatochalasis
PLOS ONE, 2017Co-Authors: Molly L Fuller, Cesar A Briceno, Christine C Nelson, Elizabeth A BradleyAbstract:PURPOSE To determine if tangent visual fields gathered during assessment of superior visual field deficits caused by blepharoptosis and dermatochalasis offer good correlation to clinical exam in a time and cost efficient manner. METHODS Prospective, observational case series. Subjects included all patients referred to a single surgeon (CCN) who underwent surgical correction of blepharoptosis and/or dermatochalasis. Preoperatively and postoperatively, upper margin-to-reflex distances were assessed. Tangent visual fields were performed in a timed fashion and analyzed for degrees of intact vision in the vertical meridian and degrees squared of area under the curve. Data were compared by Student t-tests and Pearson correlation coefficients. RESULTS Mean preoperative superior visual fields with the Eyelid in the natural position measured 8° in the vertical meridian. Measurements in the vertical meridian and area under the curve showed excellent correlation (r = 0.87). Patients with ptosis showed strong correlation between margin-to-reflex distance and superior visual fields. Patients completed field testing faster than reported times for automated or Goldmann testing. Finally, tangent screens were the least expensive type of equipment to purchase. CONCLUSIONS Tangent visual fields are a rapid and inexpensive way to test for functional loss of superior visual field in patients with upper Eyelid Malposition. Our data revealed potential differences between tangent screen results and published results for automated or Goldmann visual field testing which warrants further studies.

no histological evidence of orbicularis oculi muscle hypertrophy in congenital epiblepharon
Clinical and Experimental Ophthalmology, 2013Co-Authors: Hirohiko Kakizaki, Hyera Kang, Dinesh Selva, Hiroshi Ikeda, Yasuhiro Takahashi, Igal LeibovitchAbstract:Background: To analyse the microscopic anatomy of the orbicularis oculi muscle in patients with congenital epiblepharon and to determine whether hypertrophy of the orbicularis oculi muscle, which is considered as a possible cause of this Eyelid Malposition, exists. Methods: Sixty-seven Eyelids with congenital epiblepharon of 41 Japanese patients, as well as 30 control Eyelids of 24 Japanese patients with other Eyelid pathologies (upper Eyelid: fourteen blepharoptosis, one trichiasis and two retractions; lower Eyelid: five involutional entropions, one trichiasis and seven retractions) were analysed. These controls contained no orbicularis pathology such as cicatrization or orbitopathy. The muscle specimens were obtained from the central part of the pretarsal orbicularis oculi muscle during surgery. The specimens were stained with haematoxylin & eosin. Only specimens with cross-sectional areas that included large muscle fibres were selected. In each section, 10 muscle fibres were measured across their smallest diameter, thereby avoiding inaccurate measurements of muscle kinking occurring during the processing or by any obliquity of the plane of section. Measurements of the muscle fibre diameter were made with a digital measure. Results: There were no significant differences in the average diameter of the muscle fibres between the patients with congenital epiblepharon and the control group. Conclusions: There was no evidence of orbicularis oculi muscle hypertrophy in congenital epiblepharon.
