MICROSCOPY OF THE LIVING EYE

The interior of the eye is accessible through the clear cornea to 

 inspection as is no other region in the body, revealing as nowhere 

 else normal deep structure and its pathological alterations. The 

 conjunctiva of the lids is 

 reflected at the fornix, F 

 (Fig. 1) on to the fibrous 

 sclera, S, which it covers 

 as far as the limbus, 1, 

 having a loose and elastic 

 connection to the sclera 

 owing to the intervention 

 of lax areolar tissue in 

 which run the coarser 

 conjunctival vessels. The 

 epithelium of this ocular 

 conjunctiva becomes con- 

 tinuous with the epithelium 

 covering the clear cornea, 

 but over the cornea it is 

 immovably and integrally 

 blended with the firm 

 fibrous tissue beneath. 

 When, as the result of 

 disease of the cornea, 

 inflammatory processes — cellular and vascular — invade it, they 

 are derived from the superficial vessels of the conjunctiva when 

 the disease is a superficial one, and from the deep vessels of 

 the sclerotic, S, or ciliary body, C, when the disease is of deeper
