と、両者ともに統計学的に明確なリスク上昇が示されました(Hwang K, Kim JH. The Risk of Blepharoptosis in Contact Lens Wearers. J Craniofac Surg. 2015;26(5):e373-4)。
✅ 若年〜中年層の眼瞼下垂で最多の原因
**Kersten ら(1995年)**が Ophthalmology 誌に発表した研究では、15〜50歳の後天性眼瞼下垂患者91名を調査したところ、**コンタクトレンズ使用が眼瞼下垂の唯一の原因であった症例が47%**にのぼり、この年代における最多の原因であることが示されました(Kersten RC et al. Acquired ptosis in the young and middle-aged adult population. Ophthalmology. 1995;102(6):924-8)。
**Reddy ら(2007年)**が Ophthalmology 誌に報告した研究では、35歳未満の若年層においては、ソフトコンタクトレンズ使用が眼瞼下垂の原因として29%を占め、外傷(16%)や重症筋無力症(12%)を上回る最多の原因でした(Reddy AK et al. Ptosis in young soft contact lens wearers. Ophthalmology. 2007;114(12):2370)。
**Watanabe ら(2006年)**が American Journal of Ophthalmology 誌に発表した研究では、平均25.4年(範囲12〜40年)にわたりハードコンタクトレンズを装用してきた15名の患者様のミュラー筋を組織学的に解析しました。その結果:
15名全員のミュラー筋に線維化(fibrosis)が認められた
一方、加齢性眼瞼下垂の対照群では、ミュラー筋の線維化は軽度で、代わりに脂肪変性が主体でした(Watanabe A et al. Histopathology of blepharoptosis induced by prolonged hard contact lens wear. Am J Ophthalmol. 2006;141(6):1092-6)。
当院院長・山道が発表した論文でも、眼瞼下垂手術後に頭痛・肩こりが改善する可能性が示唆されています(Yamamichi K, Takagi S, Eto A, Ohjimi H. Infrabrow excision blepharoplasty for dermatochalasis patients can improve headache and stiff neck as well as ptosis repair for aponeurotic blepharoptosis patients. Fukuoka Med Bull. 2020)。
