CO2 Laser Lash Tilt Technique for the Treatment of Mild to Moderate Lash Ptosis and Augmentation of Upper Eyelid Blepharoplasty Results.

PURPOSE: To assess the safety, efficacy, and patient satisfaction of a newly described technique for the treatment of mild to moderate lash ptosis performed as augmentation to upper eyelid blepharoplasty. METHODS: Patient medical records for 27 consecutive cases of upper eyelid blepharoplasty between January 2016 and June 2017 and 19 consecutive cases of upper eyelid blepharoplasty with the laser lash tilt procedure between July 2016 and January 2017 performed by the senior author were retrospectively reviewed. Lash position in preoperative and postoperative photographs was graded in a randomized masked fashion on a 4-point scale by 5 oculoplastic surgeons. RESULTS: There was a significant improvement in mean lash position scores for the control group (0.52 ± 0.34, p < 0.001) with mean lash score improving from 1.14 ± 0.46 before surgery to 0.62 ± 0.46 after blepharoplasty alone. There was also significant improvement in mean lash position scores for the laser lash group (0.98 ± 0.52, p < 0.01) with mean lash score improving from 1.66 ± 0.62 before surgery to 0.68 ± 0.50 after blepharoplasty with laser lash treatment. The improvement in lash position seen in the laser lash group was significantly greater than the improvement seen in the control group (p = 0.001). There were no complications and all patients were satisfied with their results. CONCLUSIONS: Compared with upper eyelid blepharoplasty alone, the addition of the CO2 laser lash tilt technique provides a significant improvement in the upward tilt of the eyelashes as they emerge from the eyelid margin.

Facial and orbital asymmetry in oculofacial surgery patients.

Facial symmetry traditionally has been associated with beauty, and we typically strive for symmetry in surgery. However, the subtle degrees of asymmetry are natural and perhaps even more common than perfect symmetry. We retrospectively reviewed photographs of 100 oculofacial surgery patients without history of unilateral or orbital pathology or diplopia to describe the occurrence of facial asymmetries, including larger hemiface, hemiface with stronger seventh cranial nerve (measured by smile excursion and increased dynamic periocular rhytides during smile), hemiface with more pronounced rhytides at rest, difference in vertical globe height compared to interpupillary distance (IPD), higher earlobe, and higher lip. We found that most patients had static and dynamic facial asymmetry. Our data highlight the importance of counseling patients about preexisting facial asymmetry and establishing normative values for asymmetry.

Completeness of facial self-application of sunscreen in cosmetic surgery patients.

Previous studies have demonstrated incomplete sunscreen self-application to various facial regions in cosmetic surgery patients, but there is no scientific research on the completeness of facial and periocular sunscreen self-application using ultraviolet (UV) photography for assessment. This prospective, cross-sectional, qualitative study aimed to assess completeness of facial application of sunscreen in oculofacial surgery patients at the Duke Eye Center (Durham, North Carolina). Forty-four participants were enrolled, and completeness of facial sunscreen self-application was assessed using UV photography.

Rejuvenation of the Upper Face and Periocular Region: Combining Neuromodulator, Facial Filler, Laser, Light, and Energy-Based Therapies for Optimal Results.

BACKGROUND: The upper face and periocular region is a complex and dynamic part of the face. Successful rejuvenation requires a combination of minimally invasive modalities to fill dents and hollows, resurface rhytides, improve pigmentation, and smooth the mimetic muscles of the face without masking facial expression. METHODS: Using review of the literature and clinical experience, the authors discuss our strategy for combining botulinum toxin, facial filler, ablative laser, intense pulsed light, microfocused ultrasound, and microneedle fractional radiofrequency to treat aesthetic problems of the upper face including brow ptosis, temple volume loss, A-frame deformity of the superior sulcus, and superficial and deep rhytides. RESULTS: With attention to safety recommendations, injectable, light, laser, and energy-based treatments can be safely combined in experienced hands to provide enhanced outcomes in the rejuvenation of the upper face. CONCLUSION: Providing multiple treatments in 1 session improves patient satisfaction by producing greater improvements in a shorter amount of time and with less overall downtime than would be necessary with multiple office visits.

Tear osmolarity and dry eye symptoms in diabetics.

PURPOSE: To assess the relationship between tear osmolarity and dry eye symptoms in patients with diabetes. PATIENTS AND METHODS: Fifty patients with diabetes were enrolled. Demographic information and past medical history were recorded. Symptoms were assessed using the ocular surface disease index (OSDI). Tear osmolarity of each eye was measured with the TearLab® Osmolarity System. RESULTS: The majority of the subjects were female (76%), African American (56%), and/or had a diagnosis of type 2 diabetes (82%). The mean ± standard deviation (SD) for age was 54.6±13.4, and maximum tear osmolarity was 304.6±12.7 mOsm/L. Men had higher osmolarity than women (mean ± standard error (SE) 311.8±4.0 mOsm/L versus 302.3±1.9 mOsm/L, P=0.02). Age, race, use of artificial tears, years of diabetes, and hemoglobin A1c did not have a statistically significant association with tear osmolarity. Longer duration of diabetes was associated with lower (less severe) OSDI scores (r=-0.35, P=0.01). Higher tear osmolarity was associated with lower (less severe) OSDI scores (r=-0.29, P=0.04). CONCLUSION: Approximately half of the diabetic subjects in our study had elevated tear osmolarity, and half of our population also reported symptoms consistent with dry eye disease. However, the two were slightly inversely related in that those with higher osmolarity reported fewer symptoms. Subjects with a longer duration of diabetes also reported fewer dry eye symptoms. Therefore, health care providers should be aware that patients who are most likely to have ocular surface disease, including those with long-standing diabetes, may not experience symptoms and seek care in a timely manner.

Tear osmolarity in Sjögren syndrome.

PURPOSE: The Schirmer test is one of the 2 ocular surface tests included in the current classification criteria for Sjögren syndrome (SS). Tear osmolarity may also be a useful test for the diagnosis of dry eye disease. The purpose of this study was to examine the relationship between tear osmolarity, the Schirmer test I, and dry eye symptoms in SS. METHODS: Patients with a diagnosis of SS were assessed for tear osmolarity with the TearLab Osmolarity System, tear production with Schirmer testing, symptoms with the Ocular Surface Disease Index (OSDI), and discomfort associated with each test. RESULTS: Forty-nine patients with a mean age of 53.7 years and a female (92%) predominance were enrolled. The majority of patients (86%) were receiving systemic therapy for severe SS. Higher tear osmolarity was moderately associated with lower scores on the Schirmer test I (ρ = -0.39, P < 0.01) and OSDI (ρ = -0.45, P < 0.01). Schirmer test I results and lower OSDI scores were not correlated significantly (ρ = 0.20, P = 0.17). Tear osmolarity testing was significantly less painful than Schirmer testing (P < 0.01). CONCLUSIONS: Signs and symptoms of dry eye in SS patients were not strongly correlated. An unexpected finding was that higher tear osmolarity was associated with lower symptom severity. Tear osmolarity testing in the clinical setting was feasible and was associated with significantly less discomfort than Schirmer testing in patients with severe SS.

The effects of systemic, intrastriatal, and intrapallidal injections of caffeine and systemic injections of A2A and A1 antagonists on forepaw stepping in the unilateral 6-OHDA-lesioned rat.

RATIONALE AND OBJECTIVES: Given that adenosine A2A antagonists appear to be therapeutic in several animal models of Parkinson's disease (PD), we examined the extent to which caffeine and selective A2A and A1 antagonists could enhance contralateral forepaw stepping in the unilateral 6-OHDA-lesioned rat. MATERIALS AND METHODS: Following unilateral injections of 12 microg 6-OHDA into the medial forebrain bundle (MFB), frequency of stepping with both front paws was counted separately as the paws were dragged anteriorally and laterally by a treadmill. RESULTS: The MFB lesions decreased contralateral stepping by 74-83%, and 8 mg/kg 3,4-dihydroxy-L-phenylalanine (L-DOPA) increased contralateral stepping by 25-26%. Caffeine given systemically (15 mg/kg) or into the dorsal striatum or external globus pallidus (GPE; 20-40 microg) increased contralateral forepaw stepping by 14%, 27%, and 26%, respectively, and enhanced the effect of 8 mg/kg L-DOPA on stepping. The selective A(2A) antagonist SCH-58261 (2 mg/kg) also increased stepping by 13% and enhanced the therapeutic effect of L-DOPA, whereas the selective A(1) [corrected] antagonist 8-cyclopentyltheophylline (3-7 mg/kg) and A(1) agonist N(6)-cyclopentyladenosine (0.03-0.2 mg/kg) had no effect. None of these drugs appeared to produce dyskinesic effects. CONCLUSIONS: In this well-validated animal model of the akinesic effects of PD, caffeine and a selective A2A, but not an A1, antagonist were able to provide both monotherapeutic and adjunctive therapeutic effects. These data are consistent with the hypothesis that A2A antagonists may be therapeutic in human PD patients and indicate that the dorsal striatum and GPE are critical sites of therapeutic action.
