Schwalbe's line is the peripheral limit of which layer of cornea?
Ans. is 'c' i.e., Descemet's layer Histology of corneao The cornea has five distinct layers (from superficial to deep)Epithelium It is the outermost part of cornea and is composed of stratified squamous non-keratinized epithelial cells.Bowman's membrane : - It is not a true membrane but simply a condensed superficial part of stroma. Once destroyed, it does not regenerate.Stroma (Substantia propria): - This layer constitutes most of the cornea (90% of thickness). It consists of collagen fibrils (lamellae) embedded in hydrated matrix of proteoglycans.Descemet's membrane : - This layer bounds the stroma posteriorly. In the periphery it appears to end at the anterior limit of trabecular meshwork as Schwable's ring.Endothelium : - It is a single layer of flat polygnonal cells. The endothelial cells contain 'active-pump* mechanism and is the most important layer in maintaining the transparency of cornea.
