I've got dry eyes due to stevens johnson syndrome(drug-allergic).will this dryness leads to blindness?

Dry eyes: Due to stevens-johnson syndrome tend to be more severe than dry eyes due to other causes. You can experience vision loss if your eye surfaces are severely affected by this condition. Make sure you are followed closely by your ophthalmologist to reduce the risk of this happening.

Not likely: Stevens-johnson syndrome targets the anterior surface ; mucous membrane of the eye which can result in severe dryness. This can be treated with artificial tears. Sjs can also damage the cornea ; corneal stem cells resulting in scarring of the cornea. It is the corneal changes that may decrease the vision. You should follow closely with your eye doctor for management to prevent vision loss.
