Group1 named GP comprised primary pterygia
patients, while those of recurrent pterygia
were in Group 2 named GR.
were labelled grade-1 if the underlying episcleral vessels were clearly visible, grade 3 if the vessels were completely obscured by the fibrovascular fleshy mass of pterygium and grade 2 if the vesseles were partly visible.
The nasal and temporal pterygia
were marked with a sterile pen and measured, after which local anesthesia (subconjunctival lidocaine hydrochloride + 2% epinephrine) was applied (Figure 1).
