Summary
The GoCheck Kids app shows moderate accuracy in identifying amblyopia risk factors in young children. Pediatricians can use this smartphone tool to help detect vision problems, especially when cooperation for visual acuity testing is difficult.
Area of Science:
- Ophthalmology
- Pediatric eye care
- Medical technology
Background:
- The GoCheck Kids smartphone photoscreening app was introduced in 2014 for pediatrician use.
- Published validation data for the app's accuracy in detecting amblyopia risk factors (ARF) is limited.
- The American Association for Pediatric Ophthalmology and Strabismus provides guidelines for ARF detection.
Purpose of the Study:
- To evaluate the accuracy of the GoCheck Kids Screener in identifying amblyopia risk factors (ARF) in children.
- To assess the app's performance against established pediatric ophthalmology guidelines.
- To provide data for pediatricians regarding the efficacy of smartphone-based vision screening.
Main Methods:
- A validity assessment was conducted.
- 206 children aged 6 months to 6 years were included in the study.
- Children underwent GoCheck screening prior to a masked comprehensive eye examination by a pediatric ophthalmologist.
Main Results:
- GoCheck demonstrated a sensitivity of 76.0% and specificity of 67.2% for detecting ARF when compared to examination.
- Positive predictive value was 57.0% and negative predictive value was 83.0%.
- Screening was unsuccessful for 7 children (4 images not gradable, 3 failed screenings).
Conclusions:
- The GoCheck Kids smartphone app, in its evaluated version, is useful for identifying ARF in a high-risk pediatric population, particularly those unable to cooperate with traditional visual acuity tests.
- Findings inform pediatricians about the app's efficacy in detecting vision problems in young children.
- Further validation and software updates may enhance performance.

01:26Factors Affecting the Risk of Infection
13.9K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:24Drug Toxicity: Risk factors
18
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

01:24Vision
60.4K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...

1.6K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:23Factors Affecting Dissolution: Particle Size and Effective Surface Area
1.8K
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...
