Double Vision and Eye Pain: Possible Causes and Solutions - Neurology

More Info

---

Double vision, or diplopia, along with eye pain and associated symptoms like headaches, can be concerning and may arise from various underlying conditions. Given your history of occasional eye discomfort after prolonged computer use, it is plausible that your symptoms are related to eye strain or fatigue, particularly if you spend long hours in front of a screen without adequate breaks.


Possible Causes of Your Symptoms
1. Eye Strain (Asthenopia): Prolonged use of computers can lead to eye strain, which manifests as discomfort, headaches, and sometimes blurred vision. This is often exacerbated by poor lighting, glare from screens, or improper viewing distances.

2. Refractive Errors: If you have uncorrected vision issues such as nearsightedness, farsightedness, or astigmatism, these can contribute to double vision and discomfort. Even minor changes in your prescription can lead to significant symptoms.

3. Convergence Insufficiency: This condition occurs when your eyes do not work together effectively while focusing on nearby objects. It can lead to double vision, especially when looking at distant objects after prolonged near work.

4. Neurological Issues: While less common, neurological conditions can cause double vision. This includes issues with cranial nerves that control eye movement, or more serious conditions like a brain tumor. However, given that you have no other neurological symptoms, this is less likely.

5. Sinus Issues: Since you mentioned pain around the temple and eye area, sinusitis or other sinus-related issues could contribute to your symptoms. Inflammation or pressure in the sinus cavities can affect the eyes and cause discomfort.


Recommended Actions
1. Eye Examination: Since you have already seen an eye doctor and ruled out major issues, it may be beneficial to return for a comprehensive eye exam, specifically focusing on your visual acuity and binocular vision. Ask about tests for convergence and other eye coordination issues.

2. Vision Therapy: If convergence insufficiency is diagnosed, vision therapy may help improve your eye coordination and reduce double vision.

3. Screen Time Management: Implement the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This can help alleviate eye strain.

4. Proper Lighting and Ergonomics: Ensure your workspace is well-lit and that your computer screen is at eye level to reduce strain. Adjust the brightness and contrast of your screen to minimize glare.

5. Follow-Up with a Neurologist: If your symptoms persist despite addressing eye strain and you remain concerned about neurological issues, consider a follow-up with a neurologist for further evaluation. They may recommend imaging studies if deemed necessary.

6. Pain Management: For the pain around your eye and temple, over-the-counter pain relievers may provide temporary relief. However, consult with a healthcare provider for persistent pain.


Conclusion
While your symptoms can be attributed to eye strain or other benign causes, it is essential to monitor them closely. If double vision persists or worsens, or if you develop new symptoms, seek medical attention promptly. Keeping a symptom diary may also help your healthcare provider understand the frequency and triggers of your symptoms, aiding in diagnosis and treatment. Remember, early intervention can often lead to better outcomes, so don’t hesitate to seek further evaluation if needed.
