White eye, also known as blistering of the conjunctiva, may be a normal physiologic manifestation or may be associated with conjunctival inflammatory reactions due to allergies, infections and other causes.
1. Normal physiologic manifestation: proliferation of conjunctival follicles in children and adolescents does not always imply a pathologic change. Small follicles can sometimes be seen in the temporal conjunctiva of normal young people, which is a physiologic change.
2. Conjunctival inflammatory reaction: various diseases that can lead to conjunctival inflammatory reaction may occur. For example, in adenoviral keratoconjunctivitis, eyelid edema, conjunctival congestion and edema in the acute phase, follicles and subconjunctival hemorrhage appear within 48 hours.
There are many other causes of conjunctival blistering, and when microbial infections such as enterovirus type 70, coxsackievirus, and trachoma occur, there can be significant follicle formation and other manifestations. It is recommended that obvious follicles occurring in the conjunctiva should be promptly sought medical attention to improve the slit-lamp microscopy and other auxiliary examinations, and then for specific cases of the treatment guided by the recommendations of the doctor.
