RESUMEN
IMPORTANCE: It is important to establish reliable outcome measures to detect progression in retinitis pigmentosa (RP). BACKGROUND: To evaluate progression of RP using multimodal imaging, including spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF) and microperimetry (MP). DESIGN: Retrospective longitudinal study at a tertiary teaching hospital. PARTICIPANTS: 205 eyes of 106 patients with RP with 1 to 5 y of follow-up. METHODS: Demographics and visual acuity (VA) were recorded, and each modality was graded at baseline and every annual follow-up. SD-OCT was graded for the width of ellipsoid zone (EZ), FAF was graded for the diameter and area of the hyperautofluorescent ring (if present), and MP was graded for mean, central and paracentral sensitivity. Spearman's correlation was used to measure correlations at baseline. Mixed effects models were used to estimate the annual change of each parameter, adjusted for disease duration. MAIN OUTCOME MEASURES: Rate of progression. RESULTS: The median VA at baseline was 75 letters and was positively correlated with mean and central sensitivity (r: 0.372 and 0.394; P = 0.01 for both). All parameters (except paracentral sensitivity) were strongly correlated with each other (r: 0.673-0.991; P < 0.001 for all). The annual rates of change for each parameter were as follows: VA, -2.3 letters (P < 0.001); EZ, -151 µm (P < 0.001); ring diameter, -132 µm (P < 0.001); ring area, -0.4 mm2 (P < 0.001); mean sensitivity, -0.3 dB (P < 0.001); central sensitivity, -0.7 dB (P < 0.001); paracentral sensitivity, -0.4 dB (P < 0.001). CONCLUSIONS AND RELEVANCE: Structural and functional measures are well correlated in RP and can reliably measure disease progression within the course of a year.

PURPOSE: To determine the incidence, characteristics, disposition, and economic burden of emergency department (ED) visits for ophthalmic trauma in the United States (US). DESIGN: Retrospective study. METHODS: The Nationwide Emergency Department Sample was used to calculate and characterize ED visits for ophthalmic trauma in the US from 2009 to 2018. Linear regression was used to estimate trends in annual incidence and mean inflation-adjusted ED charges. Logistic regression was used to assess variables associated with inpatient admission. RESULTS: There were over 7.3 million ED visits for ophthalmic trauma in the US over the 10 years, with an annual incidence of 233 per 100,000 population. Patients were predominantly male (65 %), 21-44 years old (39 %), and from low-income households (56 %). Only 1 % of patients were hospitalized. Older age, male sex, metropolitan teaching hospitals, and trauma centers were associated with significantly higher odds of inpatient admission. The mean inflation-adjusted ED charge per visit more than doubled over the decade ($1,333 to $3,187) with total charges exceeding $14 billion. Superficial injuries (44 %) and eyelid/orbit wounds (20 %) accounted for the majority of visits. Orbital floor fractures (4 %) and open globe injuries (2 %) accounted for a minority of visits but were responsible for most admissions (49 % and 29 %, respectively) and the highest mean ED charge ($7,157 and $6,808, respectively). CONCLUSIONS: Ophthalmic trauma represents an increasingly significant burden to EDs in the US. Preventive efforts should target young males from low socioeconomic backgrounds. Strategies to improve outpatient access and redirect non-urgent injuries may help alleviate costs.

Carotid artery stenting (CAS) has emerged as an attractive alternative to carotid endarterectomy (CEA). However, CAS in a high risk patient carries significant morbidity/mortality. We report a successful CAS procedure in an extremely high risk case with a unique underlying comorbid combination not previously reported in the literature.

PURPOSE: To describe the epidemiology of Emergency Department (ED) visits related to opioid abuse with primary ophthalmic diagnoses in the United States (US). METHODS: This retrospective cross-sectional study used National ED Sample (NEDS) (2006-2015), a representative sample of all US EDs, to analyze and compare the epidemiology of primary ophthalmic diagnoses in opioid abusers and a control group of non-opioid users. National incidence and descriptive statistics were calculated for demographics and prevalent diagnoses. Multivariable logistic regression was used to compare outcomes between primary ophthalmic diagnoses in opioid and non-opioid abusers. RESULTS: An estimated 10,617 visits had a primary ophthalmic diagnosis and an accompanying opioid abuse diagnosis, and the incidence increased from 0.2 in 2006 to 0.6 per 100,000 US population in 2015. Opioid abuse group had more adults (6,747:63.5%) and middle-aged (3,361:31.7%) patients, while in controls adults (7,905,003:40.4%) and children (4,068,534:20.8%) were affected more. Leading etiologies were similar: traumatic and infectious etiologies were most common; however, opioid abuse patients had more severe ophthalmic diagnoses such as orbital fractures (8.4%), orbital cellulitis (7.4%), globe injury (3.4%) and endophthalmitis (3.2%) compared to controls. Patients in the opioid abuse group were also more likely to be admitted (adjusted Odds Ratio [aOR], 28.38 [95% CI, 24.50-32.87]). CONCLUSIONS: In the era of opioid crisis, an increase in ED visits with ophthalmic complaints is seen, with increasing direct and indirect costs on the healthcare system. More research is needed to establish causality and devise strategies to lower this burden.

OBJECTIVE: To determine and compare epidemiology, patient demographics, and socioeconomic factors of ophthalmic procedures in the United States. PARTICIPANTS: All ophthalmic ambulatory procedures performed from 2012 to 2014. METHODS: The State Ambulatory Surgery Databases (SASD), a collection of data from 29 participating states that represent two-thirds of the U.S. population, were used for analysis. All ophthalmic procedures performed in ambulatory settings from 2012 to 2014 were included. Incidence and demographics for each procedure were assessed, with descriptive statistics determined to highlight key differences in epidemiology and patient characteristics for each procedure. Population-based rates of procedures for each racial group were calculated using national census data. RESULTS: Over a period of 3 years, 3 934 004 ophthalmic procedures were performed, with majority being ambulatory (98.5%). Most common procedures were lens and cataract removal (66.5%), followed by intraocular procedures (11.4%) and procedures involving eyelids, cornea, and conjunctiva (8.2%). All ambulatory procedures had a higher number of female patients except retinal tear and detachment repairs (male patients, 59.4%). Most procedures had a higher rate in blacks compared with whites and other races, and Medicare was the most common mode of payment. CONCLUSIONS: Approximately 1.3 million ambulatory ophthalmic procedures were performed every year between 2012 and 2014 in the 29 reporting states of the United States. Low-income groups and certain minorities, apart from blacks, having a lower rate of procedure suggest that disparities exist in provision of eye care. The factors leading to these differences need to be further studied in order to devise strategies to provide equitable care.

PURPOSE: To determine the trends and disparities in inpatient costs for eye trauma in the United States from 2001 through 2014. DESIGN: Retrospective population-based cross-sectional study. METHODS: National Inpatient Sample, a representative sample of U.S. hospital discharges, was used to determine costs of eye trauma hospitalizations. Linear regression was used to estimate changes in mean inflation-adjusted cost per admission. Multivariable logistic regression was used to evaluate factors associated with a cost in the highest quartile (>$13 000) including age, sex, race, income quartile, primary payer, hospital location, size, and type. The model was adjusted for year of admission, length of stay, type of trauma, comorbidities, and the type and number of procedures performed. RESULTS: The inpatient costs for eye trauma from 2001 through 2014 totaled $1.72 billion. The mean cost (95% confidence interval [CI]) per stay remained relatively constant: $12 000 ($11 000-13 000) in 2001 to $11 000 ($10 000-12 000) in 2014 (P = .643). A cost in the highest quartile was more likely in African Americans compared to whites (adjusted odds ratio, 1.3; 95% CI, 1.2-1.5), patients in the highest income quartile compared to those in the lowest (1.3; 1.2-1.5), uninsured patients compared to publicly insured patients (1.2; 1.1-1.4), teaching hospitals compared to non-teaching ones (1.5; 1.2-1.8), and the West compared to the South (2.4; 2.0-2.8). CONCLUSIONS: Inpatient costs of eye trauma have remained steady and can be potentially reduced by addressing associated disparities. Further research including outpatient costs and eye trauma in vulnerable populations will be key to optimizing care and advancing healthcare equity.

Importance: Eye trauma is a common cause of vision loss and a substantial public health problem. Objective: To determine the changes in the incidence of eye trauma hospitalizations in the United States and compare the demographics of affected patients and outcomes of eye trauma as a primary or secondary admitting diagnosis. Design, Setting, and Participants: This retrospective longitudinal cohort study used the National Inpatient Sample, a representative sample of all US community hospitals, to determine the incidence, characteristics, and causes of primary and secondary inpatient eye trauma admissions from 2001 through 2014. All inpatients with relevant diagnoses were included. Linear regression was used to estimate changes in incidence. Logistic regression was used to compare demographics and outcomes between primary and secondary diagnoses, including age, sex, race, income, primary payer, region, year of admission, length of stay, cost, and disposition at discharge. Exposures: Eye trauma. Main Outcomes and Measures: Incidence and characteristics of inpatient primary and secondary eye trauma. Results: From 2001 to 2014, there were an estimated 939â¯608 inpatient admissions (of whom 556â¯886 were male patients [59.3%]; overall mean [SD] age, 49.4 [25.2] years) in the United States because of eye trauma diagnoses, with 778â¯967 of these (82.9%) as a secondary diagnosis. The incidence of primary eye trauma decreased from 3.9 to 3.0 per 100â¯000 population (difference, 0.9 [95% CI, 0.2-1.6] per 100â¯000 population; P = .001). The incidence of eye trauma as a secondary admitting diagnosis increased from 14.5 to 19.0 per 100â¯000 population (difference, 4.5 [95% CI, 1.9-7.2] per 100â¯000 population; P = .004). This was largely attributed to an increasing number of falls in individuals older than 65 years. The most frequent diagnosis was orbital fracture (64â¯149 [39.9%]) for primary trauma and contusion of eye and adnexa (19â¯301 [37.8%]) for secondary trauma. Primary trauma was more common in children (adjusted odds ratio [aOR], 2.21 [95% CI, 2.09-2.32]) and adolescents (aOR, 1.25 [95% CI, 1.19-1.32]) than adults (reference), African American individuals (aOR, 1.89 [95% CI, 1.81-1.97]) and Hispanic individuals (aOR, 1.52 [95% CI, 1.45-1.59]) than white individuals, and uninsured patients (aOR, 1.14 [95% CI, 1.07-1.22]) and those receiving Medicaid (aOR, 1.12 [95% CI, 1.05-1.19]) than Medicare beneficiaries. Patients with a primary diagnosis were more likely to have a stay of less than 3 days (patients with a primary diagnosis: 101â¯796 [63.4%]; secondary diagnosis: 274â¯538 [35.2%]), more likely to have costs in the lowest quartile (patients with a primary diagnosis: 51â¯212 [31.9%]; secondary diagnosis: 166â¯260 [21.3%]), and less likely to die (patients with a primary diagnosis: 526 [0.3%]; secondary diagnosis: 20â¯929 [2.7%]). Conclusions and Relevance: These findings suggest that the increasing number of falls in individuals older than 65 years and the high risk of primary eye trauma in populations such as children and adolescents warrant the development and implementation of effective preventive strategies. Many of these patients are seen in ophthalmology practices where proactive risk assessment and counseling can play a critical role.

Choroideremia is an X-linked recessive genetic disorder caused by mutations in the CHM gene. It is a rare retinal dystrophy that manifests as nyctalopia and vision loss, progressing to blindness in later stages. We report a 21-year Turkish man who presented with nyctalopia for the past 4-5 years. His mother and maternal grandmother had similar, but less pronounced complaints. Fundus examination revealed pigmentary changes and retinal atrophy in both eyes. Optical coherence tomography showed outer retinal loss, with central island of preserved autofluorescence surrounded by absent autofluorescence on fundus autofluorescence examination. Goldmann visual fields were constricted. Microperimetry detected retinal sensitivity losses, and full-field electroretinogram demonstrated extinguished cone responses. Genetic analysis revealed a novel nonsense mutation in the CHM gene, namely p.E480X: c.1438G >T. The mutation causes a premature stop codon in exon 12. This is the first report of a G1438T mutation resulting in an E480X premature stop in the CHM gene.
