Summary
This summary is machine-generated.Prior changes in spherical equivalent refractive error (SER) and axial length (AL) poorly predict future myopia progression in children. These metrics have limited clinical utility for decision-making or trial participant selection.
Area Of Science
- Ophthalmology
- Pediatric Optometry
- Myopia Research
Background
- Myopia progression is a significant concern in pediatric eye care.
- Accurate prediction of myopia progression is crucial for timely intervention.
- Previous refractive error and axial length changes are potential indicators of future progression.
Purpose Of The Study
- To evaluate the predictive value of prior changes in spherical equivalent refractive error (SER) and axial length (AL) for future myopia progression in children.
- To quantify the accuracy of using past SER and AL measurements to forecast subsequent myopia development.
Main Methods
- A post hoc analysis of a randomized controlled trial involving children aged 5-12 years.
- Data from 136 children with myopia (SER -1.00 to -6.00 D) treated with 0.01% atropine or placebo for 24 months were analyzed.
- Multivariable linear regression assessed the association between SER/AL changes over the first 12 months and the subsequent 12 months.
Main Results
- The positive predictive value of a 0.50-D SER increase in predicting a similar increase later was only 42%.
- Prior 12-month SER change showed a weak association with subsequent SER change (0.20 D per 1.00 D increase).
- Prediction intervals for future progression were negligibly improved by including prior changes in SER and AL.
Conclusions
- Changes in SER and AL over a 12-month period are poor predictors of future myopia progression in children.
- These findings suggest limited clinical utility for using prior refractive error and axial length changes in myopia management decisions.
- The predictive value is insufficient for reliably selecting participants for myopia control clinical trials.

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
