Does Dilation Eye Drops Worsen Glaucoma Symptoms? - Ophthalmology

Dilation eye drops, commonly used during eye examinations to allow the ophthalmologist to get a better view of the retina and other internal structures of the eye, can indeed have implications for patients with glaucoma, particularly those with certain types of glaucoma. In your case, with a history of high myopia (1800/1500 degrees) and glaucoma, it is understandable to be concerned about the effects of these drops on your condition.

When dilation drops are administered, they work by relaxing the muscles of the iris, which leads to the pupil widening. This can be beneficial for examining the back of the eye, but it can also pose risks for individuals with glaucoma. Specifically, in patients with narrow-angle glaucoma or angle-closure glaucoma, dilation can lead to an increase in intraocular pressure (IOP). This occurs because the widening of the pupil can cause the iris to block the drainage angle of the eye, preventing aqueous humor from exiting the eye and leading to a buildup of pressure.

However, in patients with open-angle glaucoma, which is the most common form, the effects of dilation drops are generally less concerning. While some individuals may experience a transient increase in IOP after dilation, it is usually not significant enough to worsen the condition. Nonetheless, every patient is unique, and the response to dilation can vary based on individual circumstances, including the severity of glaucoma and the specific medications used for dilation.

Given your specific situation, where you have high myopia and a history of glaucoma, it is crucial to communicate openly with your ophthalmologist. They can assess your individual risk factors and determine whether the benefits of dilation outweigh any potential risks. In some cases, they may choose to use alternative methods for examining the retina that do not require dilation, or they may monitor your IOP closely after dilation to ensure it remains within a safe range.

Additionally, it is essential to maintain regular follow-up appointments as you are already doing (weekly, monthly, and quarterly checks). This allows your eye care provider to monitor any changes in your condition and adjust your treatment plan as necessary. If you notice any significant changes in your vision or experience symptoms such as severe eye pain, headache, or sudden changes in your vision after dilation, you should contact your eye doctor immediately.

In summary, while dilation eye drops can potentially affect intraocular pressure, particularly in certain types of glaucoma, the overall impact varies by individual. It is essential to have a thorough discussion with your ophthalmologist about your specific situation, and they will guide you on the best course of action for your eye health. Regular monitoring and communication with your eye care provider are key to managing your condition effectively.
