Rapid Vision Changes: Causes and Treatment Options

Q: Rapid Vision Changes: Causes and Treatment Options

The eyes are tearing, vision is becoming increasingly blurred, and there is a feeling of approaching blindness?

A week before I enlisted, I went to get glasses, and my refractive error was measured at 150 degrees.
Now, just two months later, my vision feels increasingly blurry, to the point where it seems like I can barely see.
My eyes are tearing up, and they feel very fatigued.
Today, I went to a local hospital for an examination, and the doctor said my cornea is uneven.
He mentioned that typically, if the refractive error exceeds 400 degrees, one would not be required to serve in the military.
So why am I still being enlisted? This suggests that in just over two months, my refractive error has worsened from 150 degrees to 400 degrees.
The doctor said this is likely a matter of my physical condition and that there are various treatment options available, such as corneal transplant, laser surgery, or using rigid gas permeable lenses for correction.
However, I am still unclear about the underlying cause.

Could you please tell me what my condition is? Is there a risk that it will continue to worsen to the point of blindness? I spoke to my commanding officer, but he said that my situation does not sound urgent, so he wouldn’t allow me to take leave.
During training over the past week or two, my vision has become increasingly blurry, so I hope you can provide some insight into what might be causing this and whether it poses any danger.
Additionally, I would like to know about the costs and complexity of treatment, as well as the safety of the procedures.
I am genuinely worried.

For further context: During my enlistment medical examination, the personnel checked my eyes three times, and each measurement was significantly different, yet no issues were identified.
A few days later, they called me back for another examination, but there were still no specific notes on the examination report, only that I had a refractive error of 150 degrees.
I have mild myopia and am accustomed to wearing contact lenses.

Hello: During your vacation, please take the opportunity to get a corneal topography done at the hospital.
If it is confirmed to be keratoconus (and astigmatism exceeds 400 degrees), please have the doctor issue a certificate.
Following that, proceed gradually according to national regulations.

More Info

It sounds like you are experiencing significant and concerning changes in your vision, which can understandably be quite distressing. Based on your description, there are several potential causes for your symptoms, and I will elaborate on them as well as discuss possible treatment options.

Possible Causes of Rapid Vision Changes
1. Corneal Irregularities: The doctor mentioned that your cornea is uneven. This could indicate a condition such as keratoconus, where the cornea thins and bulges into a cone shape, leading to distorted vision. This irregularity can cause light to scatter as it enters the eye, resulting in blurred or fluctuating vision.

2. Refractive Error Progression: Your myopia (nearsightedness) seems to have worsened significantly in a short period. Rapid changes in refractive error can occur due to various factors, including hormonal changes, stress, or even excessive eye strain, especially if you are undergoing rigorous training or studying intensively.

3. Visual Fatigue: If you are experiencing increased visual demands, such as reading or focusing on screens for extended periods, this can lead to visual fatigue. Symptoms may include blurred vision, eye strain, and discomfort.

4. Underlying Health Conditions: Certain systemic conditions, such as diabetes or autoimmune diseases, can also affect vision. If you have any other symptoms or a family history of such conditions, it may be worth discussing with your healthcare provider.

5. Changes in Tear Production: You mentioned that your eyes are tearing and feeling fatigued. This could indicate dry eye syndrome, where the eyes do not produce enough tears or the right quality of tears, leading to discomfort and blurred vision.

Treatment Options
1. Corrective Lenses: Depending on the severity of your refractive error, your doctor may recommend updating your prescription glasses or contact lenses. If your cornea is irregular, specialized lenses such as rigid gas permeable (RGP) lenses or scleral lenses may be beneficial.

2. Surgical Options: If your condition is severe and does not respond to other treatments, surgical options such as corneal cross-linking (to strengthen the cornea) or laser surgery (like LASIK or PRK) may be considered. However, these options depend on the specific diagnosis and the health of your cornea.

3. Eye Drops and Medications: If dry eyes are contributing to your symptoms, artificial tears or prescription eye drops may help alleviate discomfort.
4. Regular Monitoring: Given the rapid changes in your vision, it is crucial to have regular follow-ups with an eye care professional. They can monitor your condition and make timely adjustments to your treatment plan.

Safety and Urgency
While your commanding officer may not see your situation as urgent, it is essential to advocate for your health. If your vision continues to deteriorate, it may affect your ability to perform your duties effectively and safely. You should consider seeking a second opinion or requesting a referral to a specialist, such as a corneal surgeon or a retinal specialist, who can provide a more comprehensive evaluation.

Conclusion
In summary, your symptoms could stem from a variety of causes, including corneal irregularities, rapid changes in refractive error, visual fatigue, or underlying health conditions. It is crucial to address these issues promptly to prevent further deterioration of your vision. Treatment options range from corrective lenses to potential surgical interventions, depending on the diagnosis. Regular follow-up with an eye care professional is vital to monitor your condition and adjust your treatment as necessary. Remember, your vision is precious, and taking proactive steps to protect it is essential.
