要約 背景:複視の治療では,プリズム装用による光学的治療のみでは不十分なことがある。目的:プリズム装用に加え,部分遮蔽を行った結果の報告。対象と方法:過去67か月間に治療をした複視のある患者80名を対象とした。年齢は28~86歳(平均62歳)である。複視の原因は,上斜筋麻痺16例,外転神経麻痺15例,上下偏位9例,甲状腺眼症4例などである。これら患者にプリズム眼鏡を処方し,複視が残る場合には部分遮蔽を追加した。平均30か月の経過を追った。結果:80例中72例(90%)で複視が消失した。その方法は,プリズム眼鏡の装用53例,これに部分遮蔽の追加7例,部分遮蔽のみの12例である。結論:さまざまな原因による複視に対し,プリズム装用と部分遮蔽を組み合わせることで,90%の症例で光学的な好結果が得られた。
Abstract. Purpose:To report the therapeutic outcome for diplopia with prism spectacles combined with partial occlusion. Cases and Method:This review was made on 80 patients who received treatment for diplopia in the past 67 months. They were aged from 28 to 86 years, average 62 years. Diplopia was due to superior oblique muscle palsy 16 cases, abducens palsy 15 cases, skew deviation 9 cases, and thyroid ophthalmopathy 4 cases among others. Patients were treated by prism spectacles and/or partial occlusion. Cases were followed up for an average of 30 months. Results:Diplopia disappeared in 72 cases(90%). Cure was obtained by wearing prism spectacles in 53 cases, with additional partial occlusion in 7 cases, and by partial occlusion only in 12 cases. Conclusion:Diplopia was cured in 90% of patients by wearing prism spectacles and/or partial occlusion.
