Juvenile nasopharyngeal angiofibroma (JNA) is one of the most common benign nasal cavity tumors of adolescence. This tumor has the capacity to locally expand. It can cause ocular manifestations such as proptosis, decreased visual acuity, and visual field deficits. In our case, JNA caused visual loss in both eyes. Our case showed that despite the fact that the tumor is benign, it can cause serious complications, such as blindness. Therefore, early diagnosis and treatment is crucial for this type of tumor and an ophthalmologist should be most alert for symptoms of JNA.
