Vitreous Detachment and Its Impact on High Myopia - Ophthalmology

More Info

---

Vitreous detachment, particularly in individuals with high myopia, is a significant concern due to the structural changes in the eye that can occur as a result of this condition. High myopia, defined as a refractive error greater than -6.00 diopters, is associated with elongation of the eyeball and thinning of the retina and vitreous gel. This elongation can lead to various complications, including retinal detachment, which is a serious condition that can result in vision loss if not treated promptly.

Your symptoms of experiencing flashes of light and a pulling sensation in your left eye, particularly in low light conditions, are concerning and warrant careful evaluation. The flashes of light, known as photopsia, can occur when the vitreous gel pulls on the retina, which is common in cases of vitreous detachment. The pain you describe, especially when moving your eyes or when they are open, could be indicative of increased tension in the vitreous or even early signs of retinal issues. The fact that you also experience mild redness in both eyes may suggest some level of irritation or inflammation, which can accompany these symptoms.

The normal intraocular pressure and the findings of a thin area in the optic nerve fiber layer are important indicators. While the doctor has reassured you that these findings are consistent with high myopia, it is crucial to monitor any changes closely. The recommendation for follow-up examinations, including visual field tests, is appropriate given your symptoms and history.

Regarding your concern about whether the dilated eye exam might have missed something, it is important to note that while dilation allows for a thorough examination of the retina, some conditions, such as small retinal tears or early detachment, can sometimes be subtle and may not be immediately apparent. If your symptoms persist or worsen, or if you experience new symptoms such as a sudden increase in flashes, a curtain-like shadow in your vision, or significant vision loss, you should seek immediate medical attention.

In terms of management, it is wise to continue with the prescribed eye drops and to minimize eye strain by reducing screen time and taking regular breaks. Staying hydrated and using artificial tears can help alleviate dryness, which may contribute to discomfort. Additionally, maintaining a healthy lifestyle, including a balanced diet rich in antioxidants, can support overall eye health.

In conclusion, while vitreous detachment is a common occurrence in individuals with high myopia, the symptoms you are experiencing should be monitored closely. Regular follow-ups with your ophthalmologist are essential to ensure that any potential complications are addressed promptly. If you have any further concerns or if your symptoms change, do not hesitate to reach out to your healthcare provider for further evaluation. Your eye health is paramount, and proactive management is key to preserving your vision.
