Objective Measurement of Ocular Torsion: a New Ophthalmoscopic LensDe Ancos, E.Klainguti, G.KLINISCHE MONATSBLATTER FUR AUGENHEILKUNDE
Introduction: Contact lens wearers of Asian descent may be predisposed to experience microtrauma of the ocular surface as a result a thinner post-lens tear film and higher eyelid tension, and these effects would be anticipated to be most marked in an older population. The objective of this ...
Thus, a thorough assessment of meibomian glands and the eyelid margin prior to and during contact lens wear may ensure continuous contact lens tolerance and the maintenance of a healthy ocular surface. Since meibomian glands are not overtly visible on slit-lamp biomicroscopy, imaging methods such ...
