“…These all affect the conversion factor that determines how the light distribution in the pupil is converted to the amount of defocus . Studies have shown that their refractive measurements correlate significantly with cycloplegic refraction (a strong correlation with Spot photoscreeners and a good correlation with Plusoptix photoscreeners) . While a great knowledge in eye care is not necessary to operate these instruments, the ability of the examiner to properly use the photoscreener greatly increases the reliability rate of these devices .…”

Purpose Amblyopia is a permanent visual impairment developed in early childhood. Recently, instrument‐based photoscreeners have been widely used for vision screening to detect amblyopia risk factors, which is key for the prevention and treatment of amblyopia. This meta‐analysis aims to evaluate the diagnostic test accuracy of Spot and Plusoptix photoscreeners in detecting risk factors for amblyopia in children. Methods An electronic literature search was performed in October 2018 using the MEDLINE, Embase, and Web of Science databases. Twenty‐one publications with a total of 5022 subjects were included. Subjects given a comprehensive examination were considered to have amblyopia or amblyogenic risk factors based on the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) referral criteria guidelines. Results The overall sensitivity for Spot and Plusoptix was 87.7% and 89.4%, respectively (p = 0.38); the specificity was 78.0% and 89.9%, respectively (p = 0.90). For subjects under 7 years old (preschool children), the overall sensitivity for Spot and Plusoptix was 91.7% and 90.2%, respectively (p = 0.81); the specificity was 82.6% and 93.0%, respectively (p = 0.46). Conclusion Both Spot and Plusoptix photoscreeners demonstrated good sensitivity and specificity in detecting amblyopia risk factors in children, especially at preschool ages. There was no significant difference in diagnostic test accuracy between them.

“…It should be taken into consideration that a delayed operation may result in irreversible vision loss such as amblyopia. Fortunately, widely used vision screeners allow doctors to detect risk factors for amblyopia and intervene earlier, thereby reducing the incidence of amblyopia [36,37]. Patients with other types of congenital cataracts, that do not impair the vision seriously, such as anterior, coronal, or punctate cataract, should only be followed-up closely instead of immediate surgery.…”

This meta-analysis aims to evaluate the incidence of secondary glaucoma in patients under the age of 2 years who underwent congenital cataract surgery with or without primary intraocular lens (IOL) implantation. Methods An electronic literature search was performed in Medline, EMBASE, and Web of Science databases to retrieve studies between January 2011 and November 2018. Patients with congenital cataract who did primary IOL implantation, aphakia, or secondary IOL implantation followed by receiving extraction surgery were included in this study. Relevant studies meeting defined eligibility criteria were selected and reviewed systematically by meta-analysis. Long-term incidences of secondary glaucoma, which developed at least one year after cataract surgery, were considered and discussed as clinical outcomes in each cohort. The pooled data were analyzed according to a random effects model. Results Eight publications involving 892 eyes were included in the current meta-analysis. In the general population of eyes with congenital cataract, the long-term incidence of secondary glaucoma was lower (P = 0.06) in eyes with primary IOL (9.5%) than in eyes without primary IOL (15.1%), including aphakia and secondary IOL. The pooled risk ratio (RR) favors primary IOL implantation in all patients (RR = 0.63). For bilateral congenital cataract, the incidence was 6.7% in eyes with primary IOL implantation, which is significantly lower than the 16.7%

IMPORTANCE Time spent in outdoor activities has decreased owing to home confinement for the coronavirus disease 2019 (COVID-19) pandemic. Concerns have been raised about whether home confinement may have worsened the burden of myopia owing to substantially decreased time spent outdoors and increased screen time at home. OBJECTIVE To investigate the refractive changes and prevalence of myopia in school-aged children during the COVID-19 home confinement. DESIGN, SETTING, AND PARTICIPANTSA prospective cross-sectional study using school-based photoscreenings in 123 535 children aged 6 to 13 years from 10 elementary schools in Feicheng, China, was conducted. The study was performed during 6 consecutive years (2015-2020). Data were analyzed in July 2020.EXPOSURES Noncycloplegic photorefraction was examined using a photoscreener device. MAIN OUTCOMES AND MEASURESThe spherical equivalent refraction was recorded for each child and the prevalence of myopia for each age group during each year was calculated. The mean spherical equivalent refraction and prevalence of myopia were compared between 2020 (after home confinement) and the previous 5 years for each age group. RESULTSOf the 123 535 children included in the study, 64 335 (52.1%) were boys. A total of 194 904 test results (389 808 eyes) were included in the analysis. A substantial myopic shift (approximately −0.3 diopters [D]) was found in the 2020 school-based photoscreenings compared with previous years (2015-2019) for younger children aged 6 (−0.32 D), 7 (−0.28 D), and 8 (−0.29 D) years. The prevalence of myopia in the 2020 photoscreenings was higher than the highest prevalence of myopia within 2015-2019 for children aged 6 (21.5% vs 5.7%), 7 (26.2% vs 16.2%), and 8 (37.2% vs 27.7%) years. The differences in spherical equivalent refraction and the prevalence of myopia between 2020 and previous years were minimal in children aged 9 to 13 years.CONCLUSIONS AND RELEVANCE Home confinement during the COVID-19 pandemic appeared to be associated with a significant myopic shift for children aged 6 to 8 years according to 2020 school-based photoscreenings. However, numerous limitations warrant caution in the interpretation of these associations, including use of noncycloplegic refractions and lack of orthokeratology history or ocular biometry data. Younger children's refractive status may be more sensitive to environmental changes than older ages, given the younger children are in a critical period for the development of myopia.
