Endophthalmitis is a very critical disease in ophthalmology because this disease, if not treated or controlled in a timely manner, can cause very serious effects on vision and even lead to blindness. Once endophthalmitis occurs, the first step is to give anti-infective treatment according to the specific cause, such as bacterial endophthalmitis, by applying antibiotics locally and systemically to control the local inflammation, such as antibiotic drops for eye dots, intraocular injection of antibiotics, subconjunctival injection of antibiotics, and systemic sedation, by which the inflammation is controlled in the shortest possible time to avoid damage to the retina from bacterial toxins. The prognosis for this disease is usually very poor. If treated promptly, some visual function may be preserved, but if the infecting bacteria are very virulent, then vision recovery is usually very poor.
