Managing Viral Conjunctivitis Complications: Corneal Inflammation Concerns - Ophthalmology

What are the treatment issues when viral conjunctivitis infects the cornea?

---

Hello Doctor,
On December 20th, I underwent surgery for a chalazion on my left eyelid at the ophthalmology department.
The doctor prescribed Warm Compress, to be used twice daily, as well as Jingcai eye drops and Gentamicin eye drops three times a day.
Three days later, my left eye started to become increasingly red, and despite continuing to use the eye drops, it remained red and itchy.
On December 27th, during a follow-up visit, the doctor informed me that I had contracted an adenoviral infection and needed to change my medication.
I was prescribed Dexamethasone and Patanol eye drops three times a day, and I was advised to continue using the Warm Compress.
However, after another seven days of treatment at home, my eye still did not improve; it remained red and itchy, with increasing discharge.
On January 3rd, due to the lack of improvement, I consulted a different ophthalmologist, bringing the previous doctor's prescriptions for reference.
The new doctor prescribed Betamethasone (two drops at a time), Olopatadine (three drops at a time every three hours), and allowed me to continue using the Warm Compress.
However, after three days of this treatment, my eye swelled to twice its size, and the conjunctiva became more inflamed, looking as if it was about to weep.
I began to feel dizzy and nauseous, so on the fourth night, I stopped using Betamethasone and applied ice to my eye, which slowly reduced the redness and swelling.
However, my right eye started to itch, and the amount of blood-tinged discharge increased.
I also found it difficult to see clearly with my left eye.
On January 8th, during a follow-up visit, I asked the doctor if my right eye was also infected and whether the vision impairment in my left eye indicated that the cornea was also starting to become inflamed.
After examination with instruments, the doctor confirmed that there was an infection and inflammation, stating that this was not easy to treat.
She prescribed a gentler medication: Bepotastine for the left eyelid to reduce swelling, along with Ketorolac and Patanol, one drop each every three hours.
She advised against using any of the previous medications.
I have several questions for you, Doctor:
1.
According to the information I found, Bepotastine is an antihistamine for treating eye allergies.
Educational materials indicate that corneal inflammation requires prompt medical attention, but the medication I received only addresses allergies.
Will this be effective for conjunctivitis combined with corneal inflammation? I am very concerned about the potential for permanent vision damage due to keratitis, and I fear that if this treatment does not work, the longer I wait, the worse my eye condition will become.
Currently, I can only see documents clearly when they are within 10 centimeters of my left eye while wearing glasses.
2.
My right eye is also infected, but the doctor only prescribed an antihistamine.
Will this be sufficient to suppress the viral infection? Shouldn't I be using a medication like Olopatadine, which prevents bacterial infections, as I did for my left eye?
3.
I read that Bepotastine ointment could worsen viral conjunctivitis and keratitis.
Would it be better not to apply it at all?
4.
I am very worried and having trouble sleeping.
Should I go to a major hospital's ophthalmology department for further examination? My vision has deteriorated, and I can only ask my friends to help me with my questions.
I am genuinely concerned about the possibility of blindness.
Thank you for your assistance!
