Pars Plana = part of ciliary body Acute anterior uveitis 00 Acute anterior uveitis Acute anterior uveitis is the most common form of uveitis. It is characterized by sudden onset 3. External examination shows ciliary injection around the limbus and duration of 3 months or less. e Is 1. Presentation is typically with sudden onset of unilateral pain, photophobia and redness 2 2. Visual acuity is usually good at presentation except in eyes with severe hypopyon Uni Ciliary injections (Typical for uveitis) Ciliary injections (Typical for uveitis) 4 + 5 are the main/must Acute anterior uveitis Acute anterior uveitis important sign We have to be very careful to examine hypopyon bc 4.

With appropriate therapy the so inflammation tends to completely resolve within 5– 6 weeks.  The prognosis is usually very good. Complications and poor visual prognosis are related to delayed or inadequate management. PdThe majority of cases the cause is idiopathic Fr The most common cause of anterior uveitis in ADULT is idiopathic iridocyclitis Prognosis is excellent, thanks to steroids which is the main treatment here.
