High Myopia and Glaucoma: Key Eye Health Concerns - Ophthalmology

More Info

---

High myopia, defined as a refractive error greater than -6.00 diopters, poses significant risks to eye health, particularly concerning retinal detachment and glaucoma. Your questions touch on several critical aspects of managing high myopia and associated conditions. Let's address each of your concerns systematically.

1. Heavy Lifting and Retinal Risks: While it is not strictly prohibited for individuals with high myopia to lift heavy objects, caution is advised. Heavy lifting can increase intraocular pressure (IOP) temporarily, which may pose a risk for those with pre-existing conditions like glaucoma or retinal issues. The risk of retinal detachment is heightened in individuals with high myopia due to the elongation of the eyeball, which can lead to thinning of the retina. If you must lift heavy objects as part of your job, ensure you use proper techniques and avoid straining. If you experience sudden flashes of light, a significant increase in floaters, or a shadow in your vision, seek immediate medical attention.

2. Frequency of Dilated Eye Exams: Regular dilated eye exams are crucial for monitoring the health of your retina and optic nerve, especially with your high myopia and glaucoma. A monthly examination may be excessive unless specifically recommended by your eye care provider based on your condition's severity. Generally, every 6 to 12 months is sufficient for most patients, but your doctor may suggest more frequent visits if they observe any concerning changes. Dilating drops can temporarily increase IOP in some individuals, but this effect is usually transient and not harmful in the long term.

3. Effectiveness of Eye Pressure Medications: The reduction of IOP from 22-23 mmHg to 19-20 mmHg indicates some effectiveness of your glaucoma medication, but it may not be sufficient. The target IOP varies based on individual risk factors, including the severity of glaucoma and the health of the optic nerve. If your IOP remains above the target range, your ophthalmologist may consider adjusting your medication or exploring additional treatment options. Regular follow-ups are essential to ensure your treatment plan is effective.

4. Symptoms of Retinal Detachment: If retinal detachment occurs, symptoms can vary. Some individuals may experience a sudden increase in floaters, flashes of light, or a shadow or curtain over their vision. However, not everyone will have immediate symptoms, and some may not notice anything until significant damage has occurred. Therefore, it is crucial to maintain regular eye exams and report any sudden changes in vision to your eye care provider promptly.

5. Head Positioning and Eye Pressure: Leaning forward, such as during washing your hair, can temporarily increase IOP, especially in individuals with glaucoma. However, this action alone is unlikely to cause retinal detachment. It is essential to be mindful of your head position and avoid prolonged bending or straining, particularly if you have high myopia or glaucoma.

In summary, managing high myopia and associated conditions like glaucoma requires regular monitoring and proactive care. While heavy lifting and certain activities may pose risks, understanding your condition and maintaining open communication with your eye care provider can help mitigate these risks. If you ever feel anxious about your vision or experience new symptoms, do not hesitate to reach out to your ophthalmologist for guidance and reassurance. Regular check-ups and adherence to your treatment plan are vital in preserving your vision and overall eye health.
