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.
