Pterygium Clinical Trial
Official title:
Determinants of Pterygium Occurrence and Recurrence in a Rural African Population
The aim of the study is to find out why pterygium occurs and recurs in a rural African
population. Participants will be interviewed on personal and lifestyle information, family
history of pterygium, environmental exposure and history of previous eye inflammation. They
will undergo eye examination and photography. Those with pterygium will be operated on to
remove pterygium and followed up to detect any recurrence and complications of surgery. The
excised pterygium will be examined pathologically and genetically; participant's blood will
also be examined genetically. Data will be analyzed for statistically significant
differences in findings between pterygium and pterygium free participants.
The study hypothesis is that multiple factors are responsible for the occurrence and
recurrence of pterygium in a rural african population.
