Pterygium occurs predominantly on the nasal limbus, although temporal pterygium rarely occurs in isolation. Double-head pterygium, that is nasal and temporal pterygia in the same eye is rare. In studies by Dolezalová, the incidence was found to be (2.5%).
UV light may produce damage to the cellular DNA, RNA, and extracellular matrix and may induce expression of cytokines and growth factors important in the development of pterygium.
It was described that the pterygium was associated with human papilloma virus (HPV) with the predisposing factor as dry heat and it also behaves as a neoplasm revealed by the presence of 8- hydroxydeoxyguanosine in the pterygial tissue that suggested the role of oxidative stress as a key factor in its causation.
Conjunctival autografting after pterygium excision seems to be the best method, giving both long-term safety and effectiveness in reducing the recurrence rate (2% – 39%).
The conjunctival autograft is attached with sutures, which may be associated with complicated surgical techniques, prolonged operating time, prolonged postoperative patient discomfort, and suture-related complications.
Scanty data exists evaluating success of sutureless and glue free limbal conjunctival autograft for the management of primary pterygium.
The results were very encouraging as they suggested that sutureless and glue free limbal conjunctival autografting following pterygium excision is a simple, safe, effective, without much complications and economical option for the management of primary pterygium.
The aim of the current study was to evaluate the suture less glueless conjunctival autograft for primary pterygium surgery as regard technique, complications and success rate.
