PurposeTo evaluate the prevalence and risk factors for pediatric myopia in a contemporary American cohort.MethodsA cross-sectional study of pediatric patients enrolled in the Kaiser Permanente Southern California health plan was done. Eligible patients were 5- to 19-years old between January 1, 2008, through December 31, 2013, and received an ophthalmologic or optometric refraction. Electronic medical records were reviewed for demographic data, refraction results, and exercise data. Prevalence and relative risks of myopia (defined as ≤−1.0 diopter) were characterized. Age, sex, race/ethnicity, median neighborhood income, and minutes of exercise per day were examined as risk factors.ResultsThere were 60,789 patients who met the inclusion criteria, of which 41.9% had myopia. Myopia was more common in older children (14.8% in 5- to 7-year olds, 59.0% in 17- to 19-year olds). Asian/Pacific Islander patients (OR 1.64, CI 1.58–1.70) had an increased rate of myopia compared to White patients as did African Americans to a lesser extent (OR 1.08, CI 1.03–1.13). Median neighborhood household income of $25,000–40,000 was associated with lower rates of myopia (OR 0.90, CI 0.83–0.97) compared to median neighborhood household incomes less than $25,000. Having at least 60 min of daily exercise was associated with lower prevalence of myopia (OR 0.87, CI 0.85–0.89).DiscussionMyopia was common in this large and diverse Southern Californian pediatric cohort. The prevalence of myopia increases with age. Asian children are at highest risk for myopia. Exercise is associated with a lower rate of myopia and represents an important potentially modifiable risk factor that may be a target for future public health efforts.

Bell’s palsy is an acute facial paralysis with known association to viral infections. We describe a medically complex 6-year-old male with hyper IgM syndrome who presented with unilateral facial droop and positive SARS-CoV-2 RT-PCR. This is the first reported pediatric case of Bell’s palsy in the setting of SARS-CoV-2 infection.

Patients with persistent dry eye symptoms out of proportion to clinical signs after LASIK have a syndrome that may best be classified as corneal neuralgia. In vivo confocal microscopy can be informative as to the neuropathic basis of this condition. In keeping with current understanding of complex regional pain syndrome, early multimodal treatment directed toward reducing peripheral nociceptive signaling is warranted to avoid subsequent centralization and persistence of pain. Distinguishing this syndrome from typical post-LASIK dry eye remains a challenge.

The purpose of this study was to evaluate the impact of prosthetic replacement of the ocular surface ecosystem (BostonSight PROSE, Boston Foundation for Sight, Needham, MA) treatment, utilizing customized scleral devices, on visual acuity, visual function, and ocular surface changes in patients with ocular chronic graft-versus-host disease (cGVHD). A retrospective analysis was performed on 79 eyes of 40 patients with cGVHD referred to the University of Southern California department of ophthalmology between November 2009 and July 2013 for PROSE treatment. This analysis included an assessment of ocular symptoms and visual function before and after treatment using the Ocular Surface Disease Index (OSDI) survey. Pre- and post-treatment visual acuity and clinical data were also compared. Twenty-eight male patients and 12 female patients were included in this study. The average age was 56.1 years (range, 27 to 74). Of the 79 eyes treated, 71 (90%) showed improved visual acuity with PROSE treatment. Fifty-seven eyes (72%) experienced a 2- or greater line visual acuity improvement and 14 eyes (18%) experienced a 1-line improvement. Average logarithm of the minimal angle of resolution improved from .49 ± .52 to .16 ± .44 (P < .0001), which correlates to a Snellen score improvement of approximately 20/60 to 20/30. Sixty-six of 79 eyes (84%) showed decreased corneal staining after treatment. All 9 eyes presenting with filamentary keratitis and 3 eyes with epithelial defects demonstrated complete healing of the epithelial surface after PROSE fitting. At post-treatment follow-up, 8 patients had died and 3 stopped wearing their devices. Of the remaining 29 patients, average OSDI scores improved from 72.6 ± 20.1 to 21.1 ± 14.9 (P < .0001). PROSE therapy, utilizing customized scleral lenses, can reduce ocular symptoms, improve visual acuity, and improve ocular surface integrity or appearance in patients with ocular cGVHD.

IMPORTANCEMost patients with diabetes have little or no retinopathy on initial examination. Tracking the long-term outcomes of these patients may increase our understanding of how to best provide follow-up treatment.OBJECTIVE To assess how many patients with minimal or no retinopathy require retinal intervention within 2 years of retinal evaluation. DESIGN, SETTING, AND PARTICIPANTSThis retrospective cohort study assessed patients who underwent screening for diabetic retinopathy within a telemedicine program at Kaiser Permanente Southern California and had minimal or no retinopathy on fundus photographs. EXPOSURE Retinal interventions performed within 2 years of photographs.MAIN OUTCOMES AND MEASURES Patients with minimal or no retinopathy on initial screening photographs taken in 2012 had their medical records searched for Current Procedural Terminology codes for intravitreal injections, retinal lasers, or pars plana vitrectomy. The medical records of patients identified as having received these interventions within 2 years of retinal evaluation were then manually reviewed for further characterization.RESULTS Diabetic retinopathy screening photographs were taken for 116 134 patients (mean [SD] age, 58 [12.8] years; 54 582 [47.0%] female; 46 453 [40.0%] Latino). Of these patients, 79 445, including 69 634 patients without retinopathy and 9811 patients with minimal retinopathy, had 2 years of follow-up. Eleven patients without baseline retinopathy required treatment of diabetic retinopathy in the following 2 years (1 of 12 660 or 0.000079 patients per year), and 11 patients with minimal retinopathy required intervention during the same period (1 of 1784 or 0.000561 patients per year). In addition, retinal interventions were performed for conditions not directly related to diabetic eye disease in 44 patients without baseline retinopathy (1 of 3165 or 0.000316 patients per year) and 5 patients with minimal retinopathy at baseline (1 of 3924 or 0.000255 patients per year). CONCLUSIONS AND RELEVANCEThese findings suggest that it is rare for patients with minimal or no baseline retinopathy to require retinal interventions in the 2 years after retinal evaluation. It appears that extending the recommended follow-up interval for low-risk patients may be reasonable as long as this does not lead to worse follow-up in later years, because most are unlikely to have vision-threatening disease that necessitates treatment.

Sight-threatening complications of ocular chronic graft-versus-host disease often require a multidisciplinary approach. Persistent corneal epithelial defects may require increased systemic immunosuppression and extension of PROSE treatment to overnight wear.

Background: Unused or rarely used instruments in standard surgical trays can unnecessarily increase costs. Prior studies have demonstrated the practicality and cost savings of reduced instrument tray sizes in various subspecialties. This study describes results and estimated cost savings from a reduced instrument tray used for vitrectomy surgery at a large, tertiary academic medical center. Methods: Common usage patterns of vitrectomy instruments by one retina surgeon were reviewed and a reduced instrument vitrectomy tray was created and implemented in successive vitrectomy surgeries. Need for opening the previously utilized larger tray was recorded. Estimated cost savings of the new trays were calculated based upon per instrument sterilization, processing, and instrument replacement costs. Results: New vitrectomy trays including just 7 instruments (89% reduction compared to original trays) were created and implemented in 189 successive cases. The original tray was never opened. Estimated cost savings from saved sterilization and processing resources is approximately $9588 per year. Assuming 5-and 10-year lifespan per instrument, annual cost avoidance is projected at $7886 and $15,772, respectively. Other indirect benefits relevant to healthcare quality were also noted. Conclusion: A reduced instrument tray can be successfully implemented for vitrectomy surgery and can result in significant indirect benefits as well as direct cost savings from reduced sterilization costs. Our study highlights the substantial impact made by evaluating the usage pattern and making appropriate instrument tray changes for just one retina surgeon. Applying these same methods to other surgeons and specialties can have significant implications on healthcare costs and quality.
