in front of retina with accommodation
being at rest.
, Aetiological types
Axial Myopia: Increased anteroposterior
length of eyeball.
Curvatural: Increased curvature of cornea,
lens or both.
Index: Increased refractive index of
refractive media
SOME TIMES
Positional: Anterior displacement of lens
Myopia due to excessive accommodation
occurs in patients with spasm of
