Pseudomyopia in Children: Risks, Treatments, and Management - Ophthalmology

More Info

---

Pseudomyopia, or "false myopia," is a condition often seen in children, characterized by temporary nearsightedness that can occur due to excessive near work, such as reading or using digital devices. In your child's case, the vision test results of 0.8 and 0.9 indicate relatively good visual acuity, but the refractive error of -2.50 diopters suggests that there may be an underlying issue that needs to be addressed.

The likelihood of your child having pseudomyopia is quite high, especially if the eye care professional has recommended the use of cycloplegic drops (dilating drops) to assess the true refractive error. These drops temporarily paralyze the ciliary muscle, allowing for a more accurate measurement of the eye's focusing ability without the influence of accommodation (the eye's ability to focus on near objects). If the refractive error decreases significantly after the use of these drops, it is indicative of pseudomyopia.

If, after a month of using the drops, the refractive error remains unchanged, it may suggest that your child has true myopia rather than pseudomyopia. In such cases, the management plan may include corrective lenses, and the need for long-term use of cycloplegic drops would depend on the specific diagnosis and the recommendations of the eye care professional.

Regarding the long-term use of cycloplegic drops, while they are generally safe when used as directed, there can be side effects, such as light sensitivity and blurred vision during the period of dilation. However, these effects are usually temporary. Concerns about long-term side effects are often overstated; the benefits of accurately diagnosing and managing refractive errors typically outweigh the risks.

As for the progression of myopia, it is indeed common for myopia to increase with age, particularly during periods of rapid growth in children and adolescents. Factors contributing to the progression of myopia include genetics, environmental influences, and the amount of near work performed. To help manage and potentially slow the progression of myopia, consider the following strategies:
1. Limit Screen Time: Encourage breaks from screens and near work. The 20-20-20 rule is helpful: every 20 minutes, look at something 20 feet away for at least 20 seconds.

2. Outdoor Activities: Research suggests that spending time outdoors may help reduce the risk of developing myopia. Aim for at least 2 hours of outdoor activity each day.

3. Proper Lighting: Ensure that your child has adequate lighting when reading or doing homework to reduce eye strain.

4. Regular Eye Exams: Regular check-ups with an eye care professional are crucial for monitoring vision changes and adjusting treatment plans as necessary.

5. Corrective Lenses: If your child is diagnosed with myopia, wearing prescribed glasses or contact lenses can help manage the condition effectively.

In conclusion, pseudomyopia is a reversible condition that can often be managed with appropriate interventions. If your child's vision remains unchanged after the use of cycloplegic drops, further evaluation and management will be necessary. Regular eye care and lifestyle adjustments can play a significant role in maintaining eye health and preventing the progression of myopia. Always consult with your eye care provider for personalized advice and treatment options tailored to your child's specific needs.
