Letter to the Editor: Coinfection of Adenovirus with the Members of Herpesviridae in Ophthalmic Pterygium

Recent evidence on neoplastic changes of limbal stem cells and molecular genetic abnormalities in pterygium suggested that prolonged exposure to ultraviolet (UV) radiation may promote its development. In addition, the presence of oncogenic viruses including Human papillomavirus (HPV), Cytomegalovirus (CMV), Herpes Simplex Virus (HSV) or Epstein–Barr virus (EBV) in pterygium has been reported by several studies, with prevalences ranging from very low to almost 100% of cases, probably, due to sensitivities in the technologies used, and the DNA template sequences used for Polymerase Chain Reaction (PCR) amplification [1, 2].
