    Abstract Introduction: Müller muscle conjunctival resection (MMCR) may be more likely to lead to under- rather than over-correction. The choice of revision surgery is not clearly defined.
    Methods: MMCR patients were included if the post-operated eyelid(s) demonstrated margin reflex distance-1 (MRD1) less than 3.5 mm, or if MRD1 asymmetry was greater than 0.5 mm, and if they underwent subsequent revision surgery. MRD1 was the primary outcome measure and complications were secondary outcome measures. Two groups were defined: patients who underwent MMCR then repeat MMCR (M-M) and those who underwent MMCR followed by external levator resection (ELR) surgery (M-L).
    Results: 18 eyelids (16 patients) were included, 12 in M-M and 6 in M-L. Mean (SD) preoperative MRD1 was 1.84 mm (0.97), range -0.41 to 3.39 mm. There was no difference (p = 0.70) in preoperative MRD1 between M-M and M-L. In the M-M group, mean (SD) MRD1 was 1.77 mm (1.12) preoperatively, 2.35 mm (0.66) after the first surgery, and 3.44 mm (0.31) after revision. Mean MRD1 was significantly higher after revision, compared to preoperatively (p < 0.05) and after first surgery (p < 0.05). In the M-L group (n = 6), mean (SD) MRD1 was 1.98 mm (0.90) preoperatively, 1.99 mm (0.56) after the first surgery and 3.44 mm (1.24) after revision. The difference between preoperative and post revision surgery MRD1 was significant (p < 0.05).
    Conclusions: For patients with insufficient elevation of MRD1 or with asymmetry after MMCR, revision by MMCR or by ELR are both reasonable options.

    Abstract Background: Injectable fillers have become an integral part of facial rejuvenation, but vascular occlusion is a dreaded complication of such injections.
    Objective: To determine the force required by the fingertip onto the plunger of the syringe to cause retrograde migration.
    Methods: In this cadaver study, twelve 2-cm arterial segments and 4 fillers were tested. Injection pressure required to force a column of filler for 1 cm was measured. Five oculoplastics specialists were subsequently recruited and asked to inject the filler at a typical injection pressure.
    Results: The nonhyaluronic acid filler required significantly more pressure to cause propagation of the material compared with all other fillers (p < .01). None of the other fillers differed significantly from each other. Typical injection pressures generated by experienced injectors were significantly lower than that required to cause propagation of filler at the desired velocity and significantly lower than mean arterial pressure. Measured pressure required to cause filler propagation was well within the normal range of the finger strength that can be generated by humans.
    Conclusion: Typical injection pressures from fingertip to plunger are lower than required to cause propagation of filler intravascularly.

    Abstract Purpose: To determine if early postoperative swelling has an effect on change in the upper eyelid position after external levator resection (ELR) or blepharoplasty.
    Methods: In this observational cohort study, patients >18 years old who underwent ELR or upper blepharoplasty were identified. Digital photographs in primary position were obtained at the preoperative, early postoperative week one, and late postoperative month 3 visits. Marginal reflex distance 1 (MRD1) was measured digitally. Swelling was graded on a previously validated scale from 0 to 3. Photographs were evaluated by 26 experts/professional image graders. Primary outcome measure was changed in MRD1 from preoperative to late postoperative visits. Secondary outcome measure was change in MRD1 from early to late postoperative visits. The effect of early postoperative swelling on each outcome was assessed using linear regression models.
    Results: The sample contained 54 patients (25 ELR and 29 blepharoplasty). The model regressing change in MRD1 from preoperative to late postoperative visits with early postoperative swelling as the predictor was significant for ELR (R2 = 0.165, p = 0.044) but not blepharoplasty (R2 = 0.016, p = 0.515). However, the model controlling for preoperative MRD1 was not significant for ELR (B = 0.423, p = 0.354). The model regressing change in MRD1 from early to late postoperative follow up utilizing early postoperative swelling as the sole predictor was not significant for ELR (R2 = 0.010, p = 0.627) but was significant for blepharoplasty (R2 = 0.207, p = 0.013), with increased swelling associated with greater change in MRD1.
    Conclusions: Early postoperative swelling does not affect the final MRD1 outcome of ELR or upper blepharoplasty; however, blepharoplasty patients with early postoperative swelling may experience greater increase in MRD1 over follow up.

    Abstract Purpose: To assess the association of time since primary laser-assisted in situ keratomileusis (LASIK) with flap relift success and risk for epithelial ingrowth (EI) in eyes undergoing flap relift after primary LASIK.
    Setting: Hong Kong Sanatorium & Hospital, Hong Kong Special Administrative Region.
    Design: Retrospective observational case series.
    Methods: 73 eyes with flaps relifted for refractive enhancement LASIK were included. Main outcome measures included rate of relift success and EI; associations of time since primary LASIK, sex, age at relift, year of relift, and flap creation method in primary LASIK with relift success and EI.
    Results: Of the 73 eyes included, relifting was successful in 71 eyes (97.3%). Among the successfully relifted eyes, 12 (16.9%) developed EI, of which 3 (4.2%) were clinically significant. No eyes lost more than 1 line of corrected distance visual acuity. The time since primary LASIK (up to 22 years), sex, age at relift, year of relift, and flap creation method in primary LASIK were not associated with relift success or EI.
    Conclusions: With the described surgical technique, flaps could be successfully relifted without much difficulty up to 22 years after primary LASIK with a low incidence of EI.

    Abstract Purpose: Ptosis may occur in certain cases after upper blepharoplasty. The authors aim to characterize the incidence of postoperative marginal reflex distance (MRD1) reduction after upper blepharoplasty and surgical variables that may predict this occurrence.
    Methods: In this cross-sectional study, patients > 18 years old undergoing upper blepharoplasty were screened. Patients were excluded if they had any history of ptosis and brow surgery. Data regarding the excision of skin, muscle, fat, and brow fat as well as crease formation were documented. The distance in millimeter from the center of the pupil to the upper eyelid margin in the midpupillary line (MRD1) was measured digitally. The primary outcome measure was a postoperative reduction in MRD1 of >1 mm. Secondary outcome was overall mean change in MRD1 and the incidence of ptosis as defined by a final MRD1 ≤ 2.5 mm.
    Results: The final sample consisted of 100 patients (200 eyelids) and the mean age was 55.8 years. There were 65 patients with orbicularis muscle removal, 52 patients with postseptal fat removed, and 9 patients with crease formation. Overall 15 patients developed MRD1 decrease of greater than 1 mm (5 bilaterally and 10 unilaterally) with 7 eyes demonstrating a final MRD1 of ≤ 2.5 mm. In multivariate modeling, muscle removal was found to be the only variable with significant impact on the development of MRD1 reduction > 1 mm after upper blepharoplasty (p < 0.05, odds ratio = 8.2). The other variables did not significantly contribute. The overall mean (SD) MRD1 was 3.43 mm (1.1) preoperatively and 3.62 mm (1.1) postoperatively (p < 0.01).
    Conclusions: Fifteen percent of patients demonstrated a reduction in MRD1 > 1 mm after upper eyelid blepharoplasty, and those with orbicularis resection were more likely to experience this change.The authors' study demonstrates a 15% incidence of postoperative MRD1 reduction after upper eyelid blepharoplasty. Orbicularis oculi muscle removal was significantly associated with this occurrence.

    Abstract Purpose: To determine if crowdsourced ratings of oculoplastic surgical outcomes provide reliable information compared to professional graders and oculoplastic experts.
    Methods: In this prospective psychometric evaluation, a scale for the rating of postoperative eyelid swelling was constructed using randomly selected images and topic experts. This scale was presented adjacent to 205 test images, including 10% duplicates. Graders were instructed to match the test image to the reference image it most closely resembles. Three sets of graders were solicited: crowdsourced lay people from Amazon Mechanical Turk marketplace, professional graders from the Doheny Image Reading Center (DIRC), and American Society of Ophthalmic Plastic and Reconstructive Surgery surgeons. Performance was assessed by classical correlational analysis and generalizability theory.
    Results: The correlation between scores on the first rating and the second rating for the 19 repeated occurrences was 0.60 for lay observers, 0.80 for DIRC graders and 0.84 for oculoplastic experts. In terms of inter-group rating reliability for all photos, the scores provided by lay observers were correlated with DIRC graders at a level of r = 0.88 and to experts at r = 0.79. The pictures themselves accounted for the greatest amount of variation among all groups. The amount of variation in the scores due to the rater was highest in the lay group at 25%, and was 20% and 21% for DIRC graders and experts, respectively.
    Conclusions: Crowdsourced observers are insufficiently precise to replicate the results of experts in grading postoperative eyelid swelling. DIRC graders performed similarly to experts and present a less resource-intensive option.
