Sudden Increase in Myopia: Causes and Concerns Explained - Ophthalmology

The sudden increase in myopia, or nearsightedness, can be concerning, especially when accompanied by other symptoms such as headaches, eye discomfort, and changes in eyelid appearance. Let's break down your concerns and explore the potential causes and implications.

1. Sudden Increase in Myopia: A rapid increase in myopia, such as the 50 degrees you mentioned, can occur for several reasons. One common cause is excessive near work, particularly with screens, which can lead to eye strain and a temporary worsening of vision. However, if the increase is significant and persistent, it may indicate underlying issues. In your case, the feeling of eye misalignment when looking at your phone suggests that your eyes may not be working together effectively, which can be a sign of binocular vision dysfunction or convergence insufficiency.

2. Concerns About Brain Tumors: Your worry about a brain tumor affecting the optic nerve is understandable, especially with the presence of persistent headaches. While brain tumors can indeed cause visual disturbances, they typically present with other symptoms, such as changes in vision (like double vision), significant headaches that may worsen over time, nausea, or neurological deficits. A CT scan without contrast may not always reveal subtle changes, but if your eye doctor has ruled out ocular diseases and you have had imaging done, it may be less likely that a brain tumor is the cause. However, if your headaches persist or worsen, further evaluation, possibly with an MRI, may be warranted to rule out any intracranial pathology.

3. Cervical Spine Issues: Regarding your cervical spine problems at levels C5, C6, and C7, it is possible that cervical spine issues can lead to neurological symptoms, including those affecting the eyes. The cervical spine houses nerves that can influence various bodily functions, including those related to vision. If there is nerve compression or irritation, it could potentially lead to symptoms such as eye strain or discomfort. However, it is less common for cervical spine issues to directly cause a significant increase in myopia.

4. Blood Pressure and Myopia: The relationship between high blood pressure and myopia is not straightforward. While hypertension can lead to various ocular changes, it is not typically a direct cause of myopia. However, stress and anxiety related to health concerns can elevate blood pressure, which may contribute to feelings of discomfort or strain in the eyes. It is essential to manage your blood pressure, as chronic hypertension can lead to other health issues, including those affecting the eyes.

In summary, while your symptoms warrant attention, the sudden increase in myopia may be more related to visual habits or strain rather than a serious underlying condition. It is crucial to follow up with your eye care provider, especially if symptoms persist or worsen. They may recommend a comprehensive eye exam, including tests for binocular vision function, and possibly refer you to a neurologist if there are ongoing concerns about headaches or other neurological symptoms. Additionally, managing your blood pressure and ensuring proper ergonomics while using screens can help alleviate some of the discomfort you are experiencing.
