An Analysis of Surgical Factors Associated with Clinically Significant Eyelid Edema (CSEE) in Patients Undergoing Blepharoplasty: Lid Crease Techniques Associated with CSEE.

PURPOSE: Severe postoperative edema after eyelid surgery can have negative clinical and psychological effects. In this study, we investigated whether surgical factors, including surgical techniques and suture type, were associated with clinically significant eyelid edema (CSEE). METHODS: A chart review was performed on 269 patients who underwent upper eyelid blepharoplasty with or without external levator advancement by 2 surgeons at a single institution between January 2021 and December 2022. Postoperative photos were graded by 2 physicians for eyelid edema using a standardized grading scale ranging from 0 (no edema) to 3 (severe edema). CSEE was defined either as having a grade of 3 at any point postoperatively or any grade that was 1 or greater after 90 days postoperatively. Logistic regression controlling for race was used for analysis; the statistical significance level was defined as p < 0.05. RESULTS: Of 269 patients, 56 developed CSEE. Of those who underwent blepharoplasty with mini crease enhancement (closure with every other bite incorporating levator aponeurosis), 40.5% developed CSEE versus 12.5% of those without (p < 0.001). Patients with lid crease formation using buried interrupted sutures had greater CSEE than those with externalized interrupted sutures removed at 1 week (43.8% versus 11.5%, p < 0.01). There was no increased risk of CSEE with additional procedures performed versus blepharoplasty alone. CONCLUSIONS: Patients who underwent blepharoplasty with mini crease enhancement, where more than 4 sutures are placed from skin to levator, and/or had buried suture lid crease formation had greater rates of CSEE.

Demographic and physiological factors associated with clinically significant eyelid edema in patients following upper eyelid surgery.

PURPOSE: To investigate demographic and physiological variables associated with clinically significant edema after upper eyelid surgery. METHODS: A retrospective chart review was performed on patients who underwent blepharoplasty or external levator advancement with or without lid crease formation between January 2018 and January 2021 at the University of Southern California. Age, sex, pertinent medical history (medications causing edema and comorbidities), and pertinent surgical procedures were all collected. Postoperative photos were graded by two independent physician graders on a newly developed photographic scale ranging from 0 (no edema) to 3 (severe edema). Clinically significant edema of the eyelids was defined as Grade 3 edema at any postoperative point or ≥ Grade 1 edema after 90 days post operation. Patients without postoperative photos were excluded. Mann-Whitney U test, Fisher's exact test, and χ2 test were used to compare groups with and without significant edema. All analyses were conducted using SAS version 9.4 (SAS Institute Inc.) with α=0.05. RESULTS: Out of 217 patients, East Asian participants had higher odds of developing edema than White participants (odds ratio, 7.92; CI, 3.15-19.93, p < 0.0001) and Hispanic participants (odds ratio, 3.47; CI, 1.51-7.97, p = 0.003). Southeast Asian participants also had higher odds of developing CSEE than White participants (odds ratio, 6.19; CI, 1.71-22.43, p = 0.006). Fifty-four (24.9%) patients had clinically significant edema. Although BMI, medical comorbidities, medication use, and age did not affect edema, there was a statistically significant relationship between race and incidence of edema (p = 0.0001). Those in the CSEE group were also more likely to require reoperation (p = 0.0143). CONCLUSIONS: There is a statistically significant relationship between Asian race and the incidence of clinically significant eyelid edema. CSEE is associated with a higher incidence of reoperation.

Diagnosis and Management of Acute Thrombosis in Venous Dominant Orbital Venolymphatic Malformations.

PURPOSE: To report the characteristic clinical and imaging findings in a series of patients with thrombosed orbital venolymphatic malformations. METHODS: Patients affected by acute thrombosis of an orbital venolymphatic malformation were reviewed. Clinical findings including symptoms and signs of presentation, characteristic imaging features, and clinical course are presented. RESULTS: Ten patients were identified. The mean age at presentation was 56 years. All patients presented with acute pain or pressure sensation, with the most common additional presenting symptoms being proptosis (6/10) and diplopia (5/10). CT imaging typically demonstrated a nonspecific orbital mass. Nine patients underwent MRI which revealed a soft tissue mass with peripheral rim enhancement and a central, typically T2 hypointense, core. Seven out of 10 patients were observed and had improvement in symptoms and signs without surgical intervention. Two patients underwent surgical intervention for intractable pain. CONCLUSION: Patients with thrombosis of a venolymphatic malformation often present with acute pain, proptosis, and diplopia. Characteristic MRI findings of a peripheral rim enhancing mass with a T2 hypointense core can be noted. Careful observation is a reasonable management option for cases without visual compromise or intractable pain.

Crowdsourcing Morphology Assessments in Oculoplastic Surgery: Reliability and Validity of Lay People Relative to Professional Image Analysts and Experts.

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.

Ptosis Sensitivity Threshold for the Lay Observer.

PURPOSE: This study aims to understand the degree to which ptosis is recognizable to a layperson. METHODS: Fifteen color drawings of a gender-neutral human face were created. Six faces exhibited right-sided ptosis (decreased margin reflex distance 1 and lengthened tarsal platform show) of 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, and 3 mm, respectively. Six more faces exhibited left-sided ptosis of the same amounts. The 12 ptotic faces and 3 symmetrical faces were randomly placed on three 11-inch by 14-inch sheets of paper with 5 faces on each page. Lay observers were provided 6 seconds per face to indicate whether it appeared to be asymmetrical. Statistical tests examined the observers' ability to detect asymmetry better than chance. Sex differences in correctly recognizing asymmetry in ptosis at each 0.5 mm increment were analyzed. RESULTS: One hundred thirty-one lay observers were enrolled in the study. Fifty-seven were women and 74 were men. Lay people were able to correctly recognize ptosis better than chance when the asymmetry was 1.5 mm or greater. Moreover, females were more accurate in recognizing ptosis at 1.5 mm, 2.0 mm, and 2.5 mm of asymmetry. CONCLUSIONS: Lay observers tend to recognize between 1.0 mm and 1.5 mm of ptosis on one side as being abnormal. This may have implications in the selection of candidates for ptosis surgery and the analysis of subsequent surgical outcomes.

Congenital Accessory Palpebral Fissure and Eyelid in a Newborn: A Case Report.

The occurrence of an accessory palpebral fissure and eyelid is an extremely rare phenomenon. An isolated accessory palpebral fissure and eyelid have been reported only twice in the literature, and in one case as an extension of Delleman syndrome, or oculocerebrocutaneous syndrome. The authors report a case of a full-term newborn who presented with an accessory palpebral fissure and eyelid associated with microcornea, skin polyps and tags, cutis dysplasia, and hypoplasia of the corpus callosum with an otherwise normal systemic workup and negative genetic screening. Detailed surgical management and histopathological analysis of the accessory findings are also described.

Measurement of Medial Wall Bowing and Clinical Associations in Thyroid Eye Disease.

PURPOSE: To propose and validate a measure of medial wall bowing in thyroid eye disease (TED) and to assess the clinical correlates of bowing in TED. METHODS: In this cross-sectional cohort study, all patients affected with TED seen by a single specialist over a 2-year period were screened for study entry. Eligible participants were adults with clinical evidence of TED and either CT or MRI of the orbits. Exclusion criteria included prior history of decompression surgery and/or medical or other ophthalmic conditions that could alter the orbital anatomy. The primary outcome measure was prevalence of medial wall bowing. Secondary outcomes included the associations between medial wall bowing and exophthalmometry, diplopia, rectus muscle restriction, dysthyroid optic neuropathy (DON), strabismus, and quality of life. Medial wall bowing was defined as medial divergence of the medial wall from a straight line drawn between the anterior lacrimal crest and the middle of the optic canal and measured radiographically using axial images of the orbits. Volumetric analysis of bowing was performed on a sample of orbits with and without bowing. Volumetric and axial single slice measurements were compared. Bivariate statistics were performed. RESULTS: The final sample included 112 orbital images from 56 patients with TED. Medial wall bowing was found to be evident in 11.6% (n = 13/112) of orbits. Medial wall bowing was significantly associated with greater Hertel measurements, horizontal and vertical muscle restriction, ocular surface symptoms and Clinical Activity Score, as well as lower quality of life scores. Patients with demonstrable medial wall bowing were more likely to be affected by optic neuropathy, diplopia (Gorman score ≥ 1), strabismus, or horizontal muscle restriction. Analysis of the volume for medial wall bowing demonstrated that the height of the arc at the peak of bowing on an axial image of a 2-dimensional CT scan correlated highly with the total volume of bowing (r = 0.90, p < 0.001). CONCLUSIONS: The identification of medial wall bowing on CT or MRI is associated with clinical measures of disease severity, including diplopia and DON.

Medial Buttressing in Orbital Blowout Fractures.

PURPOSE: To study whether ethmoidectomy predisposes the orbit to medial wall fracture with lesser trauma. METHODS: An interventional cadaver study of 5 heads (10 orbits); the left or right orbit was randomized to undergo endoscopic complete ethmoidectomy with the fellow orbit as control. Fractures were induced with direct globe trauma, and heads underwent CT scanning. Energy to induce fracture, peak orbital pressure at time of fracture, fracture pattern, and volume of herniated tissue were measured and analyzed. RESULTS: Fractures were induced in both orbits of all cadavers. Experimental orbits after ethmoidectomy sustained orbital fracture at less energy required (2.14 ± 0.66 vs. 3.10 ± 0.19 J, mean difference: -0.96 ± 0.33 J, p < 0.05). Similarly, peak orbital pressure was lower for ethmoidectomized orbits than for controls (11.8 ± 8.42 vs. 28.4 ± 13.2 mm Hg, mean difference: -16.5 ± 6.9 mm Hg, p < 0.05). Orbits after ethmoidectomy were more likely to sustain medial wall involvement in fracture (100%) compared with controls (20%, p < 0.05) and pure medial wall fracture (80%) compared with controls (0%, p < 0.05). Overall volume of herniated orbital contents was not significantly different between groups (p = 0.25); volume of herniated tissue from the medial wall only was significantly greater in orbits after ethmoidectomy (mean difference: 1.01 ± -0.39 cm, p < 0.05). CONCLUSION: Endoscopic ethmoidectomy in fresh cadavers reduces impact energy necessary to induce orbital fracture and increases the prevalence of medial wall involvement. Clinicians may wish to counsel patients undergoing endoscopic sinus surgery about these relative risks.

Longitudinal relationships between visual acuity and severe depressive symptoms in older adults: the Salisbury Eye Evaluation study.

OBJECTIVES: To assess the longitudinal relationship between visual acuity (VA) and depressive symptoms (DSs) among older adults. METHODS: A population-based sample of 2520 white and black individuals aged 65-84 years in 1993--1995 was assessed at baseline and at two, six, and eight years later. Presenting and best-corrected VA was assessed using early treatment diabetic retinopathy study chart. DSs were assessed using the severe depression subscale of General Health Questionnaire 28. Latent growth curve models estimated VA and DS trajectories and age-adjusted associations between trajectories. RESULTS: Best-corrected logMAR VA worsened over time (slope = 0.026, intercept = 0.013, both p < 0.001). No change in DS over time was observed (slope = -0.001, p = 0.762; intercept = 1.180, p < 0.001). However, a small change in DS was observed in participants who completed all rounds (slope = 0.005, p = 0.015). Baseline VA levels correlated with baseline DS levels (r = 0.14, p < 0.001). Baseline DS was associated with best-corrected VA change (r = 0.17, p = 0.01). Baseline best-corrected VA was not associated with DS change (r = 0.017, p = 0.8). Best-corrected VA change was not significantly associated with DS change (r = -0.03, p = 0.7). DISCUSSION: DSs are significantly associated with VA cross-sectionally, and persons with higher baseline DS scores were more likely to experience worsening VA over time. The complex relationship between visual impairment and DS suggests the need for a continued effort to detect and treat both visual decline and severe DSs in a growing elderly population.

Outcomes of Pars Plana Vitrectomy for Patients With Vitreomacular Traction.

BACKGROUND AND OBJECTIVE: To evaluate clinical and optical coherence tomography (OCT) outcomes of pars plana vitrectomy (PPV) for patients with vitreomacular traction (VMT). PATIENTS AND METHODS: Noncomparative, interventional, consecutive case series from 2007 to 2014. RESULTS: Of the 37 study eyes, patients were grouped according to the extent of VMT evident on OCT. Group 1 (18 eyes) had intraretinal cysts on OCT. Group 2 (19 eyes) had both intraretinal cysts and subretinal fluid. Visual acuity (VA) improved at least one line or more in 76% of eyes postoperatively. Postoperative VA was not significantly different across the two groups (P > .36). Postoperatively, a macular hole developed in 4 eyes (10%). After reoperation, three of four eyes achieved macular hole closure. CONCLUSIONS: Patients with VMT achieve visual and OCT improvements after PPV. Postoperative macular hole formation is uncommon but can be successfully repaired with further surgery.

Determinants of survival and resource utilization for pediatric extracorporeal membrane oxygenation in the United States 1997-2009.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) remains a vital therapy for children requiring cardiopulmonary support. METHODS: The Kids' Inpatient Database (KID) was analyzed for ECMO (ICD-9-CM 39.65) patients between 1997 and 2009. RESULTS: Overall, 8005 cases were identified, consisting of neonatal (ECMO <30days of life; 33%), infant (30days to 1year; 46%), young child (1year to 5years; 9.7%), and older child (>5years; 11%) groups. Patients were most commonly male (56%), Caucasian (49%), and insured by Medicaid (46%). ECMO was indicated for respiratory distress syndrome (RDS; 33%), cardiac and circulatory congenital anomalies (CCCA; 22%), congenital diaphragmatic hernia (CDH; 13%), and persistent pulmonary hypertension of the newborn (PPHN; 10%). On multivariate analysis, length of stay (LOS) decreased over the study period, while total charges (TC) increased over time, p<0.001. Survival was higher for boys and those treated in large or urban teaching hospitals, p<0.05. ECMO for CDH, CCCA, and RDS had the highest associated mortality, p<0.001. Neonatal and infant ECMO had no difference in mortality vs. older children. CONCLUSIONS: While LOS for ECMO has decreased over time, TC has increased steadily. Improved survival is found in boys and patients at large or urban teaching hospitals. CDH, CCCA, and RDS portend poor survival outcomes as indicators for ECMO.

Glaucoma screening in the Haitian Afro-Caribbean population of South Florida.

OBJECTIVE: To evaluate the presence of clinical signs consistent with suspected glaucoma in Haitian Afro-Caribbean individuals residing in South Florida who do not receive regular eye examinations. DESIGN: Retrospective, cross-sectional study. SETTING: Community health center in the Little Haiti district of Miami, Florida. PATIENT POPULATION: We reviewed medical records and screening forms from five health screenings between October 2011 to October 2013 of 939 Afro-Caribbean individuals older than 18 years, who were never diagnosed with glaucoma or had an eye examination within the last ten years. PROCEDURES: Measurements of distance visual acuity (VA), intraocular eye pressure (IOP), central corneal thickness (CCT), cup-to-disc ratio (CDR), frequency doubling technology (FDT) perimeter visual field (VF). MAIN OUTCOME MEASURES: Proportion of glaucoma suspects, based on IOP greater than or equal to 24 mm Hg or CDR greater than or equal to 0.7 in either eye, and determinants of CDR and IOP. RESULTS: One hundred ninety-one (25.5%) of 750 patients were identified as glaucoma suspects. Glaucoma suspects were common in both the youngest and oldest age groups (<40 years, 20.9%; 95% confidence interval [CI], 17.9-23.9; >70 years, 25.0%; 95% CI, 21.8-28.2) and higher in men than women less than 70 years; the reverse was true after 70 years. Among all patients, mean IOP was 19.2±4.5 mmHg, mean CDR was 0.37±0.17, and mean CCT was 532±37.1 µm. In multiple linear stepwise regression analysis, determinates of increased CDR included increasing age (P = 0.004), lack of insurance (P = 0.019), and higher IOP (P<0.001), while increasing CDR (P<0.001) and thicker CCT (P<0.001) were associated with higher IOP. CONCLUSIONS: This first glaucoma survey in a U.S. Haitian Afro-Caribbean population indicates glaucoma suspect status is high across all age groups, and suggests glaucoma monitoring in people less than 40 years of age is indicated in this population.

Spontaneous massive splenic infarction in the setting of renal transplant and septic shock: a case report and review of the literature.

Massive splenic infarction (MSI) is a rare phenomenon that results from compromised blood flow to more than half of the spleen. Causes of MSI include hematological disorders, coagulopathies, infection, and embolization, and, rarely, MSI is spontaneous. The mainstay of treatment is splenectomy. We report the case of a 50-year-old man with a history of renal transplant who presented with diffuse abdominal pain and rapidly developed septic shock. A computed tomographic study (CT scan) of the abdomen demonstrated MSI. The surgical team was consulted for splenectomy but conservative management was maintained and immune function preserved. The patient's clinical condition was resolved over a three-week period. This report demonstrates successful nonoperative management of a spontaneous MSI most likely secondary to hypoperfusion and a hypercoagulable state from both septic shock and renal transplant.

Visual acuity and increased mortality: the role of allostatic load and functional status.

PURPOSE: Poor vision may detrimentally impact functional status and affect allostatic load (AL), a measure of cumulative physiological wear and tear on the body's regulatory systems. We examined the direct effects of visual acuity (VA) on mortality and its indirect effect on mortality through its impact on functional status and AL in older adults. METHODS: Data from 4981 participants (age ≥ 60 years) from the 1999-2004 National Health and Nutrition Examination Survey (NHANES) with mortality linkage through 2006 were analyzed. Functional status was assessed by activities of daily living (ADL) and instrumental activities of daily living (IADL). The AL index was composed of 10 biomarkers: systolic and diastolic blood pressures, body mass index (BMI), glycosylated hemoglobin, total cholesterol, triglycerides, albumin, C-reactive protein, homocysteine, and creatinine clearance. Visual acuity was categorized as no (20/20-20/25), mild (20/30-20/40), moderate (20/50-20/80), or severe (≥20/200) visual impairment. Structural equation modeling using three mediating variables representing ADL, IADL, and AL examined the effects of VA on all-cause and cardiovascular disease (CVD)-related mortality. RESULTS: Adjusting for all covariates, a one-unit change in VA category increased mortality risk (hazard ratio [HR] = 1.17; 95% confidence interval [CI] 1.05, 1.32); IADL and AL predicted mortality (HR = 1.15; CI 1.10, 1.20 and HR = 1.13; CI 1.06, 1.20, respectively). Activities of daily living did not predict mortality (HR = 0.98; CI 0.91, 1.05). Worse VA was associated with increased AL (ß = 0.11; P = 0.013) and worse IADL (ß = 1.06; P < 0.001). Worse VA increased mortality risk indirectly through AL (HR = 1.01; CI 1.00, 1.03) and IADL (HR = 1.16; CI 1.09, 1.23). The total effect of VA on mortality including through IADL and AL was HR = 1.38 (CI 1.23, 1.54). Similar but slightly stronger patterns of association were found when examining CVD-related mortality, but not cancer-related mortality. CONCLUSIONS: Allostatic load and particularly IADL may function as mediators between VA impairment and mortality. Older adults with VA impairment could potentially benefit from interventions designed to prevent IADL functional status decline to reduce the risk of mortality.
