Pre-operative sub-conjunctival mitomycin C 24 hours before excision of recurrent pterygium

of SCMMC injection 1 month before surgery in recurrent pterygium. However, in Donnenfeld et al.’s[3] study, only 16 of the 36 eyes had recurrent pterygia, and remaining had primary pterygia. The authors[1] failed to cite Khakshoor et al.’s work who reported no recurrence after pterygium excision 1 month after sub-pterygial MMC; however, persistent whitening of sclera and hypovascularity at the site of excision occurred in 5.5% patients.[3]
