要約 目的:白内障術後の眼内レンズ(IOL)挿入眼で眼精疲労を自覚する症例をしばしば経験する。有水晶体眼では調節安静位の屈折値の変動(調節微動)が大きい眼精疲労に対して,0.05%シクロペントラート塩酸塩点眼が有効であることが報告されている。今回,白内障手術後の眼精疲労に対する0.05%シクロペントラート塩酸塩点眼治療の効果を後ろ向きに検討した。
対象と方法:白内障手術後に長期間持続する,原因が特定できない眼精疲労を自覚し,調節微動が大きい患者を対象とした。調節微動はアコモレフSpeedy-“i”(ライト製作所)を用いて高周波成分(HFC)の出現頻度を測定した。治療は0.05%シクロペントラート塩酸塩点眼を両眼就寝前1回点眼とした。点眼開始日および評価判定日に,調節微動と,問診による眼精疲労の自覚症状の評価を行った。
結果:症例は6例(男性3例,女性3例)11眼,平均年齢は68.8±5.4歳で,IOLは単焦点を4眼,多焦点を7眼(2焦点2眼,3焦点5眼)に挿入した。点眼開始日は白内障手術後平均6.8±3.0か月,評価判定日は点眼開始後平均1.7±1.2か月であった。点眼開始日に全眼で高値HFCを認め,評価判定日に全眼で高値HFCの減少を認めた。自覚症状の改善があったのは6例中4例(67%)であり,すべて多焦点IOLであった。
結論:白内障手術後のIOL挿入眼の眼精疲労は,0.05%シクロペントラート塩酸塩点眼で改善する可能性がある。
Abstract Purpose:We encounter cases of ocular fatigue after cataract surgery. It has been reported that application of 0.05% cyclopentolate is effective for phakic patients with asthenopia with accommodative spasms. We evaluated the effect of topical 0.05% cyclopentolate on pseudophakic patients with asthenopia.
Methods:In this retrospective, observational clinical study, patients with asthenopia after cataract surgery, with no known cause other than accommodative spasms were included. There were 6 patients(3 male, 3 female)with 11 eyes. 4 eyes had monofocal intraocular lenses(IOLs), and 7 eyes had multifocal IOLs. The average age was 68.8±5.4. Accommodative spasms were evaluated based on high frequency component(HFC)of micro fluctuations measured using an autorefractometer(Speedy-i, Right MFG. CO., Ltd.). We used a drop of 0.05% cyclopentolate everyday before sleep for the treatment. We evaluated accommodative spasms and subjective symptoms of asthenopia on the first day of treatment and on the evaluation day. Two-tailed Student's t-test was used for statistical analysis.
Results:Patients started their topical treatment 6.8±3.0 months postoperatively and the evaluation day was 1.7±1.2 months after initiating the treatment on average. All patients had elevated HFC values(68.6±5.0)on the day of treatment initiation and had significantly lower HFC values(58.8±2.4, p<0.01)on the evaluation day. Four of six patients, all of whom had multifocal IOLs, experienced relief from subjective symptoms.
Conclusions:Topical treatment with 0.05% cyclopentolate may be effective for asthenopia developing after cataract surgery, especially among patients with multifocal IOLs.
