Glaucoma is a disorder of the optic nerve which is also defined as the silent thief of the vision. It may lead to loss of vision if left untreated. The underlying reason is largely the increased intraocular pressure. This causative relation is the reason why glaucoma is mistakenly called as elevated eye pressure.
Visual disorders in children may negatively influence all stages of body and balance development including normal perception, communication, learning and social interaction. Refractive disorders in school-age children may result with symptoms such as eye fatigue, hyperemia, excess watering of eyes, frequently recurring mild infections due to rubbing eyes, conjunctivitis and blepharitis.
