Normal Values of Corneal Optical Densitometry Using Pentacam Scheimpflug Camera

Cornea is unique to its transparency. It has Peculiar feature of transmitting almost all the light passing through it. Corneal clarity dwindles with surgical or pathological insults i.e. infections, corneal dystrophies and degenerations [1]. This induced corneal haze impedes the light rays to pass which results in backward scattering of light [2]. Maintaining regular surveillance over resulting corneal haze is vital element of ophthalmological examination. Previously, the optical quality of cornea was assessed and monitored by standard slit lamp examination i.e. light scattering back to observer and extent of severity was graded subjectively [3-5]. This subjective evaluation tends to vary between observers. Commencement of objective method was imperative to produce more reliable and reproducible results.
