Anatomy of the CorneaThe cornea is a transparent dome-shaped structure covering the iris, lens, and anterior chamber (AC) of the eye. It accounts for nearly two-thirds of the total refractive power of the eye (Fig. 1.1a,...doi:10.1007/978-81-322-2818-9_1Soosan Jacob...

The cornea is the transparent tissue that covers the front of the eye.It forms anterior 1/6th of the outer fibrous coat of eyeball. The word cornea has come from “Kerato”. The term “Kerato” in greek means horn or shield like. Ancient Greek used to believe that cornea is derived ...
Perhaps the most obvious and also unique trait is the need for optical clarity that is absolutely essential if the cornea, aqueous chambers, lens, vitreous body, and inner retina are to function properly. Of course, optical clarity cannot be evaluated on a stained histology slide, so the patho...
The upper eyelid just cov- ers the upper aspect of the cornea for approxi- mately 2 mm. The horizontal length is approximately 30 mm. Medially and laterally the eyelids meet at an angle of approximately 60°. When we follow the palpebral fissure side- ways, the lateral canthal ...
Moving a ladder while a co-worker remained on the ladder platform led to a fall that – six months later – proved fatal, according to a Fatality Assessment and Control Evaluation (FACE) report from NIOSH. The incident occurred on December 12, 2015, when

The importance of the cornea to the ocular structure and visual system is often overlooked because of the cornea's unassuming transparent nature. The cornea lacks the neurobiological sophistication of the retina and the dynamic movement of the lens; yet, without its clarity, the eye would not be...
