Persistent Symblepharon in an Infant Following Epidemic Keratoconjunctivitis.

Epidemic keratoconjunctivitis (EKC), caused by certain species D human adenoviruses (Ads), is a highly contagious severe disease involving both the conjunctiva and cornea. The hallmark of this disease is the subepithelial infiltration of leukocytes, which results in corneal opacities that may persist for months or even years. In this case, of a 6-month-old infant, we report a symblepharon formation, a relatively rare outcome of EKC.

Contact lens visual rehabilitation in keratoconus and corneal keratoplasty.

Keratoconus is the most common corneal distrophy. It's a noninflammatory progressive thinning process that leads to conical ectasia of the cornea, causing high myopia and astigmatism. Many treatment choices include spectacle correction and contact lens wear, collagen cross linking, intracorneal ring segments implantation and finally keratoplasty.
