Aesthetic Eyelid Measurements of "Beautiful People": Gender Differences and Application for Thyroid Eye Disease Patients.

There remains a paucity of studies investigating measurements of periocular structures of people popularly seen as "beautiful." Such measurements may be helpful in establishing postoperative goals and measuring aesthetic outcomes. This study (1) identifies aesthetic measurements of the periocular structures in idealized celebrities, (2) determines gender differences in such measurements, and (3) compares these measurements to patients who underwent surgical repair of upper eyelid retraction associated with thyroid eye disease. METHODS: Digital analysis of 38 celebrity photographs in People's "Most Beautiful People" and "Sexiest Man Alive" was performed to measure image-derived (denoted with an "i") margin reflex distance (iMRD1), tarsal platform show (iTPS), brow fat span (iBFS), and iTPS:iBFS ratio. The same analysis was used for 35 women who underwent surgical repair for thyroid eye disease-related upper eyelid retraction. RESULTS: Significant gender differences (P < 0.05) were observed in celebrity metrics, with women having higher upper eyelids (longer iMRD1) (3.30 mm versus 2.50 mm), longer iTPS measurements (3.90 mm versus 2.50 mm), and larger iTPS:iBFS values (0.31 versus 0.20). Postoperative thyroid eye disease patients had significantly higher upper eyelids (longer iMRD1s) (4.80 mm versus 3.30 mm), longer iTPS (5.10 mm versus 3.90 mm), and larger iTPS:iBFS (0.37 versus 0.31) than celebrities. CONCLUSIONS: There are significant gender differences in the periocular metrics of "beautiful people." Optimal aesthetic outcomes may be more effectively obtained by achieving a preferred range of ratios than by relying on independent measurements. Although aesthetic outcomes are multi-factorial, measurements of "beautiful" people provide helpful guidelines to gauge aesthetic outcomes.

Effect of iris show on perceived upper eyelid height.

OBJECTIVE: To introduce "iris show," the amount of visible iris tissue between the superior pupil border and the upper eyelid margin, to evaluate the effect of iris show on perceived upper eyelid height, and to discuss potential nonsurgical treatment options for mild blepharoptosis. METHODS: Participants completed a survey containing 4 subject photographs. These photographs depicted images of varying iris colouration (blue, green, light brown, and dark brown) with identical upper eyelid marginal reflex distance (MRD1) values, but asymmetric pupil size/amount of visible iris show. Study participants were asked to select the eyelid that appeared "droopier," or choose "same height." Statistical analyses used 1-tailed and 2-tailed t tests. RESULTS: 390 participants completed the survey. In photographs of blue and green irides, both eyelids had equal MRD1s, but the eyelid with less iris show was perceived as more ptotic (p = 0.002 and 0.03, respectively). In patients with dark brown irides, eyelid heights were perceived as identical despite differences in iris show (p = 0.002). CONCLUSIONS: Decreased iris show corresponds to perceived lowering of the upper eyelid in light-coloured irides (e.g., blue and green), but may be less impactful in brown and/or dark brown irides where the iris tissue is less distinguishable from the pupil. Topical instillation of apraclonidine may represent a nonsurgical option for treatment of mild blepharoptosis in patients with light irides as it both elevates the upper eyelid margin and induces miosis, resulting in an increase in iris show and corresponding enhanced perception of upper eyelid elevation.

Rethinking Our Definition of Postoperative Success: A Comparative Analysis of Three Upper Eyelid Retraction Repair Techniques Using Novel Metrics to Capture Functional and Aesthetic Outcomes.

PURPOSE: To compare 3 upper eyelid retraction repair techniques and introduce novel metrics, which enhance the analysis of postoperative aesthetic outcomes. METHODS: Retrospective review with Image J 1.48 digital analysis of patients who underwent repair of thyroid-related upper eyelid retraction at the University of Iowa from 1996 to 2014 via 1 of 3 surgical techniques, septum-opening levator recession with Muellerectomy, modified septum-preserving levator recession with Muellerectomy, and modified septum-preserving full-thickness blepharotomy, was conducted. Photographs were obtained preoperatively, 3 to 6 months postoperatively, and at last follow up (>6 months) and evaluated by digital image analysis (denoted by "i"). Outcome measures assessed were marginal reflex distance (iMRD1), temporal-to-nasal ratio, tarsal platform show (iTPS), pupil to visible eyelid crease, brow fat span (iBFS), tarsal platform show to brow fat span ratio (iTPS:iBFS), and tarsal platform show minimizing power (iTPS-minimizing power). RESULTS: A total of 121 eyelids (28 septum-opening levator recession with Muellerectomy, 66 septum-preserving levator recession with Muellerectomy, and 27 septum-preserving full-thickness blepharotomy) from 74 patients were evaluated with a mean follow up of 24.2 months. There were no statistically significant differences between techniques in terms of iMRD1 or temporal-to-nasal ratio reduction at either time point (intertechnique p values of 0.17 to >0.99). The percentage of eyelids from subjects undergoing bilateral intervention that achieved a final iMRD1 between 2.50 mm and 4.50 mm was similar (intertechnique p value of 0.23), with no difference regarding the number of subjects demonstrating iMRD1 symmetry within 1 mm (intertechnique p value of 0.15). Though iTPS elongation was greater at 3 to 6 months with septum-opening compared with the combined septum-preserving techniques (p value of 0.04), this difference was not maintained at final follow up (p value of >0.99). There was no difference in terms of iTPS symmetry at time of final follow up (intertechnique p value of 0.69). The pupil to visible eyelid crease was unchanged in all techniques (p values >0.99). Mean changes in iBFS at final follow up were -1.27 mm, -0.44 mm, and +0.55 mm for septum-opening levator recession with Muellerectomy, septum-preserving levator recession with Muellerectomy, and septum-preserving full-thickness blepharotomy (p values of 0.01, 0.49, and >0.99, respectively). Mean iTPS:iBFS ratios at final follow up were not statistically different between techniques (intertechnique p value of 0.10) and no difference in symmetry was demonstrated (intertechnique p value of 0.47). Median values for iTPS-minimizing power were: -0.83, -0.93, and -1.01 for septum-opening levator recession with Muellerectomy, septum-preserving levator recession with Muellerectomy, and septum-preserving full-thickness blepharotomy, respectively (intertechnique p value of 0.54). CONCLUSIONS: Each technique appropriately lowered the eyelid and improved contour without intertechnique variability. Septum-preserving techniques demonstrated less iTPS elongation initially, but this difference was not maintained. The visible eyelid crease height (pupil to visible eyelid crease) remained stable in all techniques, indicating that the iTPS elongation seen with each technique was secondary to reduction in iMRD1 and the iBFS reduction seen with septum-opening levator recession with Muellerectomy was due to brow descent. No intertechnique differences in the amount of iTPS elongation relative to iMRD1 reduction (i.e., the novel iTPS-minimizing power) were seen. Given that each procedure evaluated yielded similar results, technique selection may be guided by surgeon experience and preference.

Optical Coherence Tomography-Assisted Limbal Dermoid Removal.

This report and accompanying video show the novel use of intraoperative optical coherence tomography (OCT) in the excision of a limbal dermoid. Examining for residual opaque tissue in the cornea accompanied by OCT imaging is a useful technique to confirm complete excision of the lesion. [J Pediatr Ophthalmol Strabismus. 2017;54:e58-e59.].
