Pseudomyopia and discomfort in the eyes after using tropicamide?


Hello, a 9-year-old child recently had an eye examination at school, and compared to last year, their vision changed from 1.1 to -2.50 diopters in one eye, indicating myopia.
The doctor prescribed tropicamide to be administered once in each eye at bedtime.
After two days of use, the child reported discomfort in one eye (around 11 PM), so the drops were not used on the third day.
Should the eye drops continue to be administered? The doctor mentioned a follow-up appointment in one month to check for any improvement in myopia.

Myopia does not seem to be severe; if there is any discomfort, it is advisable to take a break and consult a physician.

When managing discomfort from Tropicamide in the treatment of pseudomyopia, it's essential to understand both the medication's purpose and its potential side effects. Tropicamide is an anticholinergic agent primarily used to dilate the pupils during eye examinations. It temporarily paralyzes the ciliary muscle, which controls the lens's shape, allowing for a more comprehensive assessment of the eye's refractive state. In children, this is particularly important as their eyes are still developing, and accurate measurements are crucial for diagnosing conditions like pseudomyopia.

In your case, your 9-year-old child experienced discomfort after using Tropicamide. This discomfort could be attributed to several factors, including the dilation of the pupils, which can lead to increased sensitivity to light (photophobia) and difficulty focusing. These side effects are generally temporary and should resolve as the medication wears off, typically within a few hours. However, if the discomfort persists or worsens, it is advisable to consult with the prescribing physician.

Given that the doctor recommended using Tropicamide for two days and then returning for a follow-up, it's important to weigh the benefits of continued use against the discomfort your child is experiencing. If the discomfort is mild and manageable, it may be worth continuing the treatment as prescribed, especially since the follow-up appointment is intended to assess any changes in the child's vision. However, if the discomfort is significant enough to affect your child's daily activities or quality of life, it would be prudent to discontinue the use of the drops and inform the doctor of the situation.

In addition to the discomfort from the medication, it's also essential to consider the underlying condition of pseudomyopia. Pseudomyopia is often a temporary condition caused by excessive near work, leading to a spasm of the ciliary muscle, which can make distant objects appear blurry. Treatment typically involves reducing near work, ensuring proper lighting, and taking regular breaks during activities that require prolonged focus on close objects. In some cases, corrective lenses may be recommended to alleviate symptoms.

If your child continues to experience discomfort or if there are concerns about the effectiveness of the treatment, it may be beneficial to seek a second opinion from another eye care professional. They can provide additional insights and alternative treatment options that may be more suitable for your child's specific needs.

In summary, while Tropicamide is a common and generally safe medication for dilating pupils, discomfort can occur. It's crucial to monitor your child's symptoms and communicate with the prescribing physician about any adverse effects. Balancing the need for effective treatment with your child's comfort is key, and adjustments can be made based on their response to the medication.
