Snow banking is typically seen in
INTERMEDIATE UVEITIS (PARS PLANITIS): *It denotes inflammation of pars plana pa of the ciliary body and most peripheral pa of the retina.*Etiology: It is an idiopathic disease usually affecting both eyes (80 percent) of children and young adults. Pars planitis is a rather common entity, constituting 8 percent of uveitis patients.*Clinical features:Symptoms: Most of the patients present with a history of floaters. Some patients may come with defective vision due to associated cystoid macular edema.Signs: The eye is usually quiet. A slit-lamp examination may show mild aqueous flare and fine Keratic Precipitates at the back of the cornea. Anterior vitreous may show cells. Fundus examination with indirect ophthalmoscope reveals the whitish exudates present near the ora serrata in the inferior quadrant. These typical exudates are referred as snowball opacities. These may coalesce to form a grey-white plaque called snow banking. *Complications of long-standing pars planitis include cystoid macular edema, complicated cataract, and tractional retinal detachment.*Treatment:1. Coicosteroids administered systemically and as repeated periocular injections may be effective in some cases.2. Immunosuppressive drugs may be helpful in steroid-resistant cases.3. Peripheral cryotherapy is also repoed to be effective.Ref: Khurana; 4th edition; Pg.No.161
