Punctate inner choroiditis (PIC) is an inflammatory choroiditis which occurs mainly in young women. Symptoms include blurred vision and scotomas. Yellow lesions are mainly present in the posterior pole and are between 100 to 300 micrometres in size. PIC is one of the so called white dot syndromes which come under the heading posterior uveitis. PIC has only been recognised as a distinct condition, or type of posterior uveitis, as recently as 1984 when Watzke identified 10 patients who appeared to make up a distinct group within ==Clinical presentation== • Typically affects short sighted (myopic) women. (90% of cases are female). • The average age of patients with PIC is 27 years with a range of 16–40 years. • Patients are otherwise healthy and there is usually no illness, which triggers the condition or precedes it. • The inflammation is confined to the back of the eye (posterior). There is no inflammation in the front of the eye (anterior chamber) or vitreous (the clear jelly inside the eye). This is an important distinguishing feature of PIC. • It usually affects both eyes. • The appearance of gray-white or yellow punctate (punched out) areas (lesions) at the level of the inner choroid. These lesions are typically located centrally at the back of the eye (posterior pole). Symptoms typically include: # Blurring of vision # Partial ‘blind spots’ or scotoma. These areas of diminished or lost areas of the visual field are typically near the centre of vision but occasionally can be peripheral. These may be temporary or permanent. # Seeing flashing lights. This is known as photopsia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Punctate inner choroiditis」の詳細全文を読む スポンサード リンク
