Sudden blindness in a six-year-old child may be caused by eye trauma, glaucoma and central retinal artery blockage.
1. Eye trauma: If a six-year-old child’s eye is suddenly traumatized, such as optic nerve injury or rupture of the eyeball, it may lead to vision loss and sudden blindness.
2. Glaucoma: Children with primary acute closed angle glaucoma may experience a sudden and significant loss of vision due to the sudden closure of the intraocular angle, resulting in a sharp rise in intraocular pressure, as well as eye swelling and pain, nausea, vomiting and other uncomfortable symptoms.
3. Central retinal artery occlusion: Children with central retinal artery occlusion may experience a sudden loss of vision, even to the point of light perception, due to ischemia of the eye.
It is recommended that children with vision loss consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
