PURPOSE To assess surgical outcomes of lower lid reconstruction surgery using auricular conchal tissue. METHODS This prospective study included 20 patients that underwent reconstructive lower lid surgery using autologous auricle chondral-perichondral graft tissue. Auricle tissue was used to provide adequate support and protection with similar conjunctiva tarsal structures on overlying soft ti...

The ocular surface-a continuous epithelial surface with regional specializations including the surface and glandular epithelia of the cornea, conjunctiva, and lacrimal and meibomian glands connected by the overlying tear film-plays a central role in vision. Molecular and cellular events involved in embryonic development, postnatal maturation, and maintenance of the ocular surface are precisely ...

The corneal epithelium plays a critical role in maintaining the cornea's transparency and its avascularity. Severe damage to the limbal region results in serious problems with the corneal surface such as persistent epithelial defects, conjunctivalisation with vascularisation, keratinisation, scarring, etc. with associated profound visual loss. In order to rescue such damaged ocular surfaces, co...

introduction 3d reconstruction of an object from its 2d cross-sections (slices) has many applications in different fields of sciences such as medical physics and biomedical engineering. in order to perform 3d reconstruction, at first, desired boundaries at each slice are detected and then using a correspondence between points of successive slices surface of desired object is reconstructed. mate...
