| Outline of Final Research Achievements |
Velocity distribution and wall shear stress in the vitreous chamber during vitrectomy and after gas tamponade has been measured by use of eye model 4 times larger in its dimension. The maximum shear stress was 48Pa at 25G and 59Pa at 20G irrigation port during vitrectomy, and 12Pa after gas tamponade where linear acceleration was applied to the model partially filled with water. These shear stress were comparable to retinal adhesive strength such as 4~266Pa.
