Inflammatory exudation in the vitreous body includes both endogenous and exogenous causes. It usually requires medical treatment and is more difficult to recover on its own, and the prognosis is related to the timing of treatment, etiology, and the stage of the disease, so it is not possible to make a generalization. Vitreous inflammation usually occurs after various types of damage to the ocular tissues, including endogenous or exogenous, endogenous is mainly caused by pathogenic microorganisms entering the eye from the bloodstream or lymphatic fluids, resulting in infection, while exogenous is usually caused by surgical endophthalmitis, or by rupture of the eyeball caused by an external force, or by the entry of a foreign body into the eye. Generally speaking, for vitreous inflammatory exudate can consider using eye drops, even though antibiotic drops can enter the anterior chamber, but it is difficult to penetrate deep into the vitreous, so this approach to the treatment of intraocular inflammation is generally limited, a more effective way is to inject antibiotics into the vitreous so that the antibiotics can reach the effective concentration of intraocular therapy to achieve therapeutic effects. Inflammatory intravitreal exudates need to be treated as early as possible to maximize the prognosis.
