Blurred vision?

Hello Doctor: My condition started around mid-December when I experienced sharp pain and tearing in my right eye.
I later visited an ophthalmologist who diagnosed me with a corneal ulcer.
The doctor prescribed eye drops for treatment, and the pain subsided.
However, my vision in the right eye deteriorated significantly, from 1.0 to 0.2.
When I returned to the clinic, the doctor mentioned that there was a layer of haze on my right cornea affecting my vision, which could not be corrected with glasses.
The doctor also prescribed medication for me, but there hasn't been much improvement.
Now, I find it very difficult to see, and my right eye gets easily fatigued; everything appears blurry (similar to astigmatism).
What could be the cause of this? What should I do now? What is the worst-case scenario for my right eye? Thank you.

Subject: Corneal Ulcer.
Explanation: A 24-year-old developed a corneal ulcer, likely caused by wearing contact lenses.
If treated early, corneal ulcers can prevent the formation of corneal scars; however, most patients will have some degree of scarring upon healing.
If the scar is located in the center of the cornea, vision will be further impaired, potentially making it impossible to obtain a proper prescription.
Whether significant astigmatism develops can be determined through an eye examination.
Of course, a successful corneal transplant may resolve your issues, but with your current vision of 0.2, a corneal transplant is not recommended, as there is a high risk of rejection or infection post-surgery.
It is advised that you continue with outpatient follow-up.
Your worst-case scenario is likely your current condition.
Additionally, after assessment, your corneal scar may be considered for removal using laser ablation.

More Info

Corneal ulcers, also known as corneal epithelial defects or keratitis, are serious eye conditions that can lead to significant vision impairment if not treated promptly and effectively. Understanding the causes, symptoms, and treatment options is crucial for anyone experiencing issues related to corneal ulcers.

Causes of Corneal Ulcers
Corneal ulcers can arise from various factors, including:
1. Infections: Bacterial, viral, fungal, or parasitic infections can lead to corneal ulcers. For instance, contact lens wearers are particularly at risk for bacterial infections due to improper lens hygiene.

2. Injury: Any trauma to the eye, such as scratches from foreign objects or chemical exposure, can disrupt the corneal surface and lead to ulceration.

3. Dry Eye Syndrome: Insufficient tear production can result in corneal dryness, making the cornea more susceptible to damage and infection.

4. Underlying Conditions: Certain systemic diseases, such as diabetes or autoimmune disorders, can increase the risk of developing corneal ulcers.

Symptoms of Corneal Ulcers
The symptoms of corneal ulcers can vary but typically include:
- Eye Pain: This can range from mild discomfort to severe pain, especially when blinking.

- Redness: The affected eye may appear red and inflamed.

- Tearing: Increased tear production is common, often accompanied by a discharge.

- Blurred Vision: Vision may become cloudy or distorted, as you have experienced.

- Sensitivity to Light: Photophobia, or sensitivity to light, is a common symptom.

Treatment Options
The treatment for corneal ulcers depends on the underlying cause but generally includes:
1. Antibiotic or Antifungal Eye Drops: If the ulcer is due to an infection, your doctor will prescribe appropriate eye drops to combat the infection.

2. Pain Management: Analgesics may be recommended to manage pain associated with the ulcer.

3. Artificial Tears: For those with dry eyes, using lubricating eye drops can help maintain moisture and promote healing.

4. Surgical Intervention: In severe cases where the ulcer does not respond to medical treatment, surgical options such as corneal transplantation may be necessary.

Your Current Situation
From your description, it seems that you initially experienced pain and tearing, which led to a diagnosis of a corneal ulcer. While the pain has subsided with treatment, the subsequent development of a "film" over your eye that is affecting your vision is concerning. This could be due to scarring or a persistent epithelial defect, which can occur after a corneal ulcer heals improperly.

The fact that your vision has deteriorated from 1.0 to 0.2 indicates a significant change, and the inability to correct your vision with glasses suggests that the underlying issue may be more complex than a simple corneal ulcer. The "foggy" vision you describe could be due to corneal scarring, irregularities, or even the development of a cataract as a secondary complication.

Next Steps
1. Follow-Up with an Eye Specialist: It is crucial to return to your ophthalmologist for a thorough examination. They may perform tests such as corneal topography or optical coherence tomography (OCT) to assess the cornea's surface and determine the best course of action.

2. Consider Additional Treatments: Depending on the findings, your doctor may recommend further treatments, such as specialized contact lenses, additional medications, or surgical options.

3. Monitor Symptoms: Keep track of any changes in your symptoms, including increased pain, redness, or changes in vision, and report these to your doctor immediately.

In conclusion, corneal ulcers are serious conditions that require prompt and effective treatment to prevent complications. Your current symptoms warrant further investigation, and I encourage you to seek a follow-up appointment with your eye care provider to address your concerns and explore potential treatment options.
