Fluctuating Astigmatism: Causes and Solutions - Ophthalmology

More Info

---

Fluctuating astigmatism can be a perplexing issue, especially when it manifests suddenly or changes frequently. Astigmatism occurs when the cornea, the clear front surface of the eye, is irregularly shaped, causing blurred or distorted vision. In your case, the changes in the degree and axis of astigmatism in your right eye, particularly after an incident where your glasses were damaged, warrant a thorough examination and understanding of potential causes.


Possible Causes of Fluctuating Astigmatism
1. Corneal Changes: The cornea can change shape due to various factors, including trauma, keratoconus (a condition where the cornea thins and bulges), or post-surgical changes. The incident where your glasses broke may have led to a temporary or permanent alteration in the corneal shape.

2. Dry Eye Syndrome: Fluctuating vision can also be attributed to dry eyes, which can cause the tear film to become unstable. This instability can lead to variations in vision quality throughout the day.

3. Refractive Surgery: If you have undergone any refractive surgery (like LASIK), changes in the corneal shape can lead to fluctuating astigmatism.

4. Systemic Conditions: Certain systemic health issues, such as diabetes or autoimmune diseases, can affect the eyes and lead to changes in vision. Your mention of low platelet and white blood cell counts could indicate an underlying condition that might be affecting your ocular health.

5. Contact Lens Wear: If you wear contact lenses, improper fitting or wearing them for extended periods can cause corneal warpage, leading to fluctuating astigmatism.


Recommendations for Management
1. Comprehensive Eye Examination: Since multiple eye clinics have not identified the cause, consider seeking a second opinion from a corneal specialist or a comprehensive eye care center that can perform advanced diagnostic tests, such as corneal topography, to map the surface of your cornea.

2. Monitor Systemic Health: Given your recent blood tests showing low platelet and white blood cell counts, it is crucial to consult with a healthcare provider to rule out any systemic conditions that could be contributing to your eye issues. Conditions like autoimmune disorders can have ocular manifestations.

3. Consider Dry Eye Treatment: If dry eyes are suspected, treatments such as artificial tears, punctal plugs, or medications like cyclosporine (Restasis) may help stabilize your tear film and improve vision.

4. Review Glasses and Contact Lens Prescription: Ensure that your current prescription is accurate and that your lenses are properly fitted. Sometimes, even a slight change in prescription can significantly affect vision quality.

5. Lifestyle Adjustments: Maintain proper hydration, manage screen time, and take regular breaks to reduce eye strain. These measures can help alleviate symptoms associated with dry eyes and fluctuating vision.

6. Follow-Up: Regular follow-up appointments with your eye care provider are essential to monitor any changes in your vision and to adjust your treatment plan as necessary.


Conclusion
Fluctuating astigmatism can be challenging to diagnose and manage, especially when the underlying cause is not immediately apparent. It is essential to approach this issue holistically, considering both ocular and systemic health factors. By working closely with your eye care provider and possibly other specialists, you can develop a comprehensive plan to address your vision concerns effectively.
