要約 目的:春季カタル(VKC)は小児に発症し長期の治療を必要とする。ステロイド点眼薬の長期使用により眼圧上昇などの合併症が危惧されるため,その代替治療として行っているトリアムシノロンアセトニド(TA)眼瞼皮下注射の長期間の臨床経過を検討した。
対象と方法:対象は2009年1月〜2018年12月の10年間に福岡大学病院でVKCに対しTA眼瞼皮下注射を受けた41例64眼。平均観察期間は35.7±32.5月(0〜119月)。診療録をもとに,性別,年齢分布,季節性,注射回数,複数回注射を必要とした患者の初診時年齢および投与間隔,注射前後の点眼薬,合併症について後ろ向きに検討した。
結果:男性35例,女性6例,年齢は4〜32歳で平均11.4±6.18歳。TA眼瞼皮下注射は合計で139回施行され,うち23回(16.5%)は7月,21回(15.1%)は3月に施行された。1眼当たりの注射回数は1〜13回で,平均3.39±3.40回であった。複数回の注射を必要としたものは男性14例,女性4例であった。その平均年齢は9.17±3.99歳(4〜19歳),平均投与間隔は11.0±6.07月(1〜35月)であった。合併症は3例に眼圧上昇,1例に麦粒腫,1例に睫毛伸長が認められ,眼圧上昇がみられたものは男性1例,女性2例であった。
結論:難治性のVKCに対するTA眼瞼皮下注射は,TA眼瞼結膜下注射やステロイド内服でしばしばみられる眼圧上昇をきたすことが少ない。手技が簡便で投与間隔が比較的長いことから,安全な治療法であることが示唆された。
Abstract Purpose:Vernal keratoconjunctivitis(VKC)often has its onset in childhood with a long-term treatment. Intraocular pressure(IOP)elevation due to corticosteroid treatment is a great concern as complication. We report subcutaneous supratarsal injection of triamcinolone acetonide(TA)as an alternative treatment for corticosteroid eye drops.
Cases and methods:Forty-one patients, 64 eyes, treated by subcutaneous supratarsal injection of TA at Fukuoka University Hospital in the decade from January 2009 to December 2018 were evaluated. The mean observation period was 35.7±32.5 months(0〜119 months). Patients' gender, age, seasonality, number of injection, age at first injection, interval between injections, eye drops before and after first injection and complications were analyzed by medical records retrospectively.
Results:Thirty-five patients were male and 6 were female, mean patient age was 11.4±6.18(range;4〜32 years)years. Total number of TA injection was 139, of these, 23 injections were done(16.5%)in July, 21 were done(15.1%)in March. Mean cumulative injection was 3.39±3.40(range;1〜13)for each eye. Eighteen patients needed multiple TA injections. Of these patients, 14 were male and 4 were female, mean age was 9.17±3.99(range;4〜19 years)years. Mean interval between injections was 11.0±6.07(range;1〜35 months)months. As complications, IOP elevation occurred in 3 patients(1 male, 2 females), hordeolum in 1 patient and extended lashes in 1 patient.
Conclusions:IOP elevation was very rare in cases treated with subcutaneous supratarsal injection of TA for refractory VKC compared to subconjunctival TA injection or systemic corticosteroid. It is suggested that this way of TA injection is a safe treatment, because its technique is easy and its interval between injections was long.
