Human papillomavirus in pterygium

Area of Science:

• Ophthalmology
• Virology
• Oncology

Background:

• Pterygium is a common ocular condition.
• The role of viral infections, specifically Human Papilloma Virus (HPV), in pterygium pathogenesis is not fully understood.
• Previous research suggests a potential link between HPV and ocular surface growths.

Purpose of the Study:

• To investigate the presence and prevalence of Human Papilloma Virus (HPV) antigen in pterygium tissues.
• To explore the association between HPV positivity and epithelial proliferation in pterygium.
• To determine the etiological role of HPV in pterygium development in the Cukurova region.

Main Methods:

• Examination of consecutive pterygium cases and normal conjunctival tissues between August 1991 and 1992.
• Detection of polyclonal Human Papilloma Virus (HPV) antigen using the avidin-biotin-complex technique.
• Histopathological assessment for epithelial proliferation in HPV-positive tissues.

Main Results:

• Human Papilloma Virus (HPV) positivity was detected in 16 out of 16 pterygium cases and 25% of control conjunctivas.
• Epithelial proliferation was observed in six of the HPV-positive pterygium tissues.
• HPV infection was found to be sporadic, not endemic, in the Cukurova region.

Conclusions:

• Human Papilloma Virus (HPV) infection may play a role in the development of pterygium.
• The co-occurrence of HPV with epithelial hyperplasia suggests its potential involvement in the development of ocular neoplasia.
• Patients with HPV-positive pterygium require long-term follow-up for monitoring possible malignant transformation.
