| Outline of Final Research Achievements |
Pars plana vitrectomy and scleral buckling are used to treat rhegmatogenous retinal detachments that lead to blindness. However, conventional intraocular illumination techniques are invasive and cumbersome. In this study, we developed a prototype of a non-invasive intraocular illumination device. Using an optical fiber and an ultra-small mirror, light from a light source was successfully transmitted from the cornea to the intraocular area. Fundus imaging was performed in a simulated eye and a pig eye.

本研究で眼科手術における眼外からの眼内照明機器のプロトタイプを開発した．模擬眼と豚眼において眼底撮影に成功しているが，まだヒトでの安全性の確認などはできていない．しかしながら，安全性を担保し，医療機器として製造されれば，網膜剥離の術式選択に幅が生まれ，より理にかなった術式選択をもたらし，網膜剥離からの失明を防げる．さらに網膜剥離だけでなく，黄斑円孔や網膜前膜，糖尿病網膜症といった疾患への手術にも応用できる．
