Ophthalmic Pterygium
Pterygia are common ocular surface lesions thought to originate from limbal stem cells altered by chronic UV exposure. Traditionally regarded as a degenerative condition, pterygia also display tumor-like features, such as a propensity to invade normal tissue and high recurrence rates following resection, and may coexist with secondary premalignant lesions. This study was initiated to determine ...
متن کاملhuman adenoviruses role in ophthalmic pterygium formation
BACKGROUND Ophthalmic pterygium is a common benign lesion of unknown origin and the pathogenesis might be vision-threatening. This problem is often associated with exposure to solar light. Recent evidence suggests that potentially oncogenic viruses such as human papillomavirus and Epstein-Barr virus may be involved in the pathogenesis of pterygia. Expression of specific adenovirus genes such as...

results of 50 patients, 20 were men and 30 women with mean age of 61.1 ± 16.9 years ranged between 22 and 85 years. all samples of pterygia had positive results for adenoviruses dna with polymerase chain reaction, but none of the negative control groups displayed adenoviruses. the pterygium group and the control groups were β-globin positive. direct sequencing of pcr products confirmed adenovir...
متن کاملViral involvement in the pathogenesis and clinical features of ophthalmic pterygium (Review)
Pterygium is a potentially vision-threatening fibrovascular lesion originating from the conjunctiva that often extends on the corneal surface. Although it has been extensively studied, its pathogenesis has yet to be fully elucidated. Recent evidence on molecular genetic abnormalities in pterygium suggested neoplastic changes of limbal stem cells potentially associated with exposure to ultraviol...
متن کاملLetter 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...
