summary

Peripheral uveitis, also known as intermediate uveitis, mainly invades the pars plana of ciliary body and the periphery of fundus. It is often accompanied by retinal vasculitis, which can cause various serious complications and seriously affect vision. It is a relatively common chronic uveitis. So how does peripheral uveitis return a responsibility? Now follow me to learn.

How does peripheral uveitis return a responsibility?

First, the etiology is unknown, which may be related to immune factors. The former includes infection caused by bacteria, fungi, spirochetes, viruses and parasites; The latter includes idiopathic, autoimmune, rheumatic diseases, traumatic, camouflage syndrome, etc. The etiology and pathogenesis of uveitis are mainly due to the invasion of external pathogens or internal heat; Most of them are related to the dysfunction of liver, kidney and spleen.

Secondly, most patients with intermediate uveitis have occult symptoms. Some patients may not have any clinical symptoms. They are only found to have intermediate uveitis during ophthalmic physical examination, but more patients complain of dark shadow, blurred vision and temporary myopia. The visual acuity of the patients was more than 0.5, but the visual acuity decreased significantly when cystoid macular edema and other complications occurred. In the case of acute vitreous hemorrhage and retinal detachment, sudden severe visual loss may occur.

Finally: the diagnosis of intermediate uveitis is mainly based on clinical manifestations, especially on the following clinical features: the number of inflammatory cells in vitreous is more than that in anterior chamber, typical snowball opacity in vitreous, characteristic snowbank like lesions, cystoid macular edema, retinal vasculitis and perivasculitis.

matters needing attention

The benign type of intermediate uveitis has self limitation, and most cases can maintain visual acuity above 0.5. After the complications of vascular occlusion type and severe type, the visual impairment is significant, especially after cystic macular edema forming cystic degeneration, the visual impairment can not be reversed. It needs to be treated in time. The disease is quite serious.
