Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Endophthalmitis is also called vitreous inflammation. Broadly speaking, it refers to all kinds of serious intraocular inflammation, such as vitreitis, anterior chamber empyema and eye pain caused by intraocular infection, intraocular foreign body, tumor necrosis, severe non infectious uveitis, lens cortex allergy, etc. Clinically, it generally refers to infectious endophthalmitis caused by bacteria, fungi or parasites. According to the different ways of infection, it can be divided into exogenous endophthalmitis and endogenous endophthalmitis. Exogenous endophthalmitis is more common. When inflammation involves sclera or extraocular orbital tissue, it is called "panophthalmia".

Endophthalmitis is a kind of serious intraocular inflammation which can lead to the loss of visual function. Early diagnosis and treatment is the key. Studies have found that the changes of cytokines in aqueous humor are helpful for the diagnosis of endophthalmitis. Okhrvai et al. Also pointed out that the application of PCR can reduce the diagnosis time of endophthalmitis. This study mainly verified the use of molecular biology technology to detect the changes of VCAM, ICAM-1 and other cytokines, bacteria, viruses, fungi, Toxoplasma gondii IgG in patients' intraocular fluid, including aqueous humor and vitreous humor, so as to timely judge the etiology and progress of endophthalmitis, and provide reference for diagnosis and treatment.
