55歳男性が両眼の飛蚊症と霧視で受診した。約2か月前から感冒様症状,意識障害,播種性血管内凝固症候群があり,中心静脈栄養を受けていた。視力は良好で,軽い硝子体混濁があった。両眼の霧視はその後増悪し,7か月後に乳頭浮腫と嚢胞様黄斑浮腫が生じた。全身検査で原因は特定できなかった。右眼に診断的硝子体手術を行い,後部硝子体膜が乳頭面に癒着していた。ステロイド薬の全身投与を行い,右眼の炎症所見は消退した。持続する左眼の乳頭浮腫と黄斑浮腫に対し,硝子体手術で硝子体の乳頭牽弓を解除した。乳頭浮腫と黄斑浮腫は速やかに改善した。ぶどう膜炎の原因は特定できなかったが,硝子体の乳頭牽引が慢性ぶどう膜炎様の炎症に関与する可能性が考えられた。
A 55-year-old male presented with bilateral blurring of vision with floaters. He had been receiving intravenous hyperalimentation for disturbed consciousness and disseminated intravascular coagulation. He showed slight vitreous opacity with full visual acuity. He developed bilateral disc edema and cystoid macular edema 7 months later. Diagnostic vitrectomy showed firmly attached vitreous onto the disc. Systemic corticosteroid induced resolution of inflammatory lesions in his right eye. His left eye received therapeutic vitrectomy later to release firm vitreopapillary adhesion. Topical corticosteroid induced rapid resolution of inflammatory lesions. While the cause of uveitis could not be identified, marked response to vitrectomy seemed to show that vitreopapillary traction may have been a major factor for persistent intraocular inflammation.
