Prevalence of Body Dysmorphic Disorder in Orbital Plastic Surgery and Its Relationship with the Use of Social Media
BACKGROUNDThe prevalence of body dysmorphic disorder (BDD) in the general population ranges from 0.7 to 2.4%; however, higher rates are seen among aesthetic patients. Given the recent rise in popularity of cosmetic surgery, particularly in the post-COVID pandemic setting, the authors hypothesize the prevalence has increased. The purpose of the study is to examine the prevalence of BDD in patients presenting to an oculoplastic surgery clinic at an academic center and determine correlation with social media use. METHODSThis is a survey of patients presenting to the oculoplastic surgery clinic. Participants completed the Dysmorphic Concern Questionnaire (DCQ), in addition to survey questions about social media use. Main outcomes included a positive screen and social media use. RESULTSA total of 175 patients that presented to the oculoplastic and reconstructive surgery clinic were surveyed. All patients, including cosmetic, functional, and non-surgical, were offered participation in the survey. 9.13% of all patients screened positive for BDD. Patients that screened positive were more commonly female (71.43%). The distribution of patients with BDD was even between Hispanics (52.38%) and non-Hispanics, and 85.71% of patients with BDD were Caucasian. Of patients that screened positive, 71.43% use social media. CONCLUSIONSThe prevalence of BDD may have increased in the past seven years and is seen most in females and Caucasians. There is a positive correlation with social media, which has increased in popularity since the COVID-19 pandemic. It is important to maintain a high clinical suspicion for BDD and consider screening if there is concern.

The effects of topical oxymetazoline on eyelid position, eye redness, and patient-reported eye appearance: A randomized controlled trial
This study assesses the effects of topical oxymetazoline 0.1% on eyelid position, eye redness, and patient-perceived eye appearance in patients without severe ptosis.
This is a randomized double-blinded controlled trial conducted at a single institute. Patients aged 18-100 years were randomized to receive one drop of oxymetazoline hydrochloride 0.1% or placebo bilaterally. Marginal reflex distance (MRD) 1 and 2, palpebral fissure height, eye redness, and patient-perceived eye appearance were assessed at baseline and two hours after drop instillation. Primary outcome measures included the change in MRD1, MRD2, and palpebral fissure height. Secondary outcome measures included changes in eye redness and patient-perceived eye appearance after drop instillation.
In total, 114 patients were included, 57 treatment patients (mean age 36.4 ± 12.7 years, 31.6% male) and 57 controls (mean age 31.3 ± 10.1 years, 33.3% male). Baseline mean MRD1, MRD2, and palpebral fissure were similar between groups (p = 0.24, 0.45, and 0.23, respectively). Changes in MRD1 and eye redness in the treatment group were significantly greater than those in the control group (0.9 ± 0.9 mm vs. - 0.3 ± 0.4 mm, p < 0.001; - 2.6 ± 4.4 vs. - 0.5 ± 2.3, p = 0.002, respectively). Patient-perceived eye appearance was significantly improved in the treatment group compared to the controls (p = 0.002), with more treatment group patients also reporting increased eye size and decreased eye redness (p = 0.008, p = 0.003, respectively). There were 9 treatment-emergent adverse events (TEAEs) in 7 treatment group patients and 5 TEAEs in 5 control patients (p = 0.25), all of which were mild in severity.
Topical oxymetazoline 0.1% increases MRD1 and palpebral fissure height, decreases eye redness, and improves patient-perceived eye appearance

Changes to Eye Whiteness and Eyelid/Brow Position With Topical Oxymetazoline in Aesthetic Patients
Background: Oxymetazoline hydrochloride 0.1% ophthalmic solution has recently been approved in the United States for the treatment of ptosis.
Objectives: The aim of this study was to assess the upper and lower eyelid position as well as the brow position and the color of the sclera following the ophthalmic administration of oxymetazoline hydrochloride 0.1%.
Methods: In this prospective cohort study, consecutive patients presenting with ptosis received topical oxymetazoline 0.1%. The primary outcome was measurement of the upper eyelid height (margin-to-reflex distance 1 [MRD1]) and lower eyelid height (MRD2) relative to the center of pupil, along with assessment of brow height, measured on photographs at baseline and 2 hours after instillation of oxymetazoline. The secondary outcome was the assessment of the color of the sclera (eye whiteness) before and after treatment with a novel color space algorithm.
Results: Twenty-nine patients participated in the study. The mean [SD] MRD1 at baseline was 2.3 [0.6] mm. At 2 hours following oxymetazoline treatment, the mean MRD1 significantly increased to 4.2 [0.9] mm (P = 2 is considered visually perceptible to the human eye.
Conclusions: Within 2 hours of use, oxymetazoline significantly improves the size of the palpebral aperture (MRD1 + MRD2) and also makes the eye appear significantly whiter

The Association Between Computerized Tomography Findings and Ocular Trauma Score in Open Globe Injury: The Prognostic Value of Imaging
PURPOSEThe aim of this study was to evaluate the association between CT findings and Ocular Trauma Score (OTS) in open globe injury. METHODSIn 182 eyes with open globe injury, CT findings were categorized into 5 major types: scleral irregularity with decreased globe volume, dislocation of the crystalline lens, abnormal vitreous density, thickening of the chorioretinal layer, and intraocular foreign body/air. Association between different types and number of CT findings with OTS stages were evaluated through a multivariate analysis. RESULTSMean age of the patients was 38 ± 8.5 years. The most common CT findings were severe scleral irregularity or globe collapse (71.9%) and abnormal vitreous density (56%). The most common OTS stages were II (44.5%) and I (30.7%). In multivariate analysis, abnormal vitreous density (odds ratio [OR] = 2.11, p < 0.001), chorioretinal thickening (OR = 1.89, p < 0.001), and intraocular foreign body/air (OR = 1.58, p = 0.001) were associated with more advanced OTS stages (I or II). Mean OTS in eyes with 1, 2, and 3 CT findings were 66 (stage III), 47 (stage II), and 37 (stage I), respectively (p value = 0.008). Presence of 2 (OR = 2.46, p < 0.001) and 3 (OR = 2.92, p < 0.001) CT findings were associated with more advanced OTS stages (I or II). CONCLUSIONSThe type and number of CT findings may help to predict the OTS stage and visual prognosis in eyes with open globe injury
Effect of synthesis catalyst on structure of nitrogen-doped carbon nanotubes and electrical conductivity and electromagnetic interference shielding of their polymeric nanocomposites
Different catalysts including Co, Fe, and Ni were used to synthesize nitrogen-doped carbon nanotubes (N-CNTs) by chemical vapor deposition technique. Synthesized N-CNTs were melt mixed with a polyvinylidene fluoride (PVDF) matrix using a small scale mixer at different concentrations ranging from 0.3 to 3.5 wt%, and then compression molded. The characterization techniques revealed significant differences in the synthesis yield and the morphological and electrical properties of both N-CNTs and nanocomposites depending on the catalyst type. Whereas Co and Fe resulted in yields comparable to industrial multiwalled CNTs, Ni was much less effective. The N-CNT aspect ratio was the highest for Co catalyst, followed by Ni and Fe, whereas nitrogen content was the highest for Ni. Raman spectroscopy revealed lowest defect number and highest N-CNT crystallinity for Fe catalyst. Characterization of N-CNT/PVDF nanocomposites showed better dispersion for N-CNTs based on Co and Fe as compared to Ni, and the following order of electrical conductivity and electromagnetic interference shielding (from high to low): Co > Fe > Ni. The superior electrical properties of (N-CNT)Co nanocomposites were ascribed to a combination of high synthesis yield, high aspect ratio, low nitrogen content and high crystallinity of N-CNTs combined with a good state of N-CNT dispersion
