要約 目的:真生会富山病院アイセンターにおける遮光眼鏡処方の傾向の報告。
対象と方法:2010年6月〜2015年1月に羞明を訴え遮光眼鏡を処方した61名を対象とし,屋外用として処方した遮光眼鏡の色,視感透過率と疾患,良いほうの視力値の関係を検討した。
結果:処方した遮光眼鏡の色はグリーン系75.4%,ブラウン系13.1%,グレー系11.5%であった。どの疾患においてもグリーン系が最も多かった。糖尿病網膜症では他疾患と比べブラウン系(38.5%)が多かった。網膜色素変性,緑内障,加齢黄斑変性症では,視感透過率25%以下の濃いものが半数以上であった。
結論:遮光眼鏡の色や透過率において疾患による特異な傾向はなかったが,グリーン系のレンズはどの疾患でも多かった。
Abstract Purpose: To present a review of prescriptions for absorptive lenses in our institution.
Cases and Method: This study was made on 61 cases who received prescription for absorptive lenses for photophobia in the past 55 months. The series comprised 30 males and 31 females. The age ranged from 12 to 87 years, average 68 years. Photophobia was apparently due to retinitis pigmentosa 17 cases, diabetic retinopathy 13 cases, glauoma 9 cases and age-related macular degeneration 6 cases among others.
Results: The color of absorptive lens was green in 46 cases(75%), brown in 8 cases(13%), and gray in 7 cases(12%). Brown lenses were more frequently prescribed for patients with diabetic retinopathy. Dark lenses with absorption by 75% or greater were prescribed for more than 50% of patients with retinitis pigmentosa, glaucoma, or age-related macular degeneration.
Conclusion: Green lenses were more frequently prescribed for all type of eye diseases causing photophobia.
