Oral antivirals do not prevent eye inflammation in shingles patients

Shingles in the eye is a serious condition that can threaten vision. A recent analysis looked at whether taking daily oral antivirals could prevent a specific complication called stromal keratitis. This inflammation affects the cornea and can cause scarring. The researchers followed 527 patients for 12 months to see if the daily medication made a difference. They compared those taking the drug to those taking a placebo. The main goal was to protect sight by stopping the inflammation before it started. The results showed no difference in vision between the two groups. Stromal keratitis happened in 105 of the 527 participants regardless of the pill they took. This means the daily antiviral did not stop the inflammation from developing. The study also tracked how doctors treated the inflammation once it appeared. About 50 percent of patients received steroid eye drops. The type of steroid mattered less than the timing of the treatment. Many patients who stopped steroids earlier had to restart them later. This suggests that watching the eye closely is more important than the daily pill. The team found that low-potency steroid drops were a safe option for managing the inflammation. Patients generally kept good vision when doctors monitored them carefully. The study confirms that the daily antiviral alone is not enough to prevent this specific eye problem. Doctors should focus on recognizing the signs early and treating them quickly with drops.
