            Abstract : 
This paper discusses the deformation of macula of retina by applying a compulsory eye pressure increase through a probe with force gauge. By using the caribration data between the eye pressure and the force gauge, we impart the force corresponding to 50 [mmHg] of eye pressure to eyelid. Through OCT data before and after compulsory eye pressure increase, we analyze the deformation of macula for three different layers. An interesting observation is that macula suffered by glaucoma has thinner layer and smaller deformation than that of normal subjects, especially the characteristic is enhanced in both the surface and bottom layers, while it is not in the middle layer.
