Pre- and intraoperative mitomycin C for recurrent pterygium associated with symblepharon.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTreatment of recurrent pterygium associated with symblepharon usually involves the use of tissue grafting and/or the intraoperative application of mitomycin C (MMC). For the graft, a conjunctival/limbal autograft and/or amniotic membrane may be used. This generally requires extra technical skills and assistance, an increase in the cost and duration of surgery, and a more extensive anesthesia (a complete eye block or general anesthesia). Although widely used, safety concerns have been raised over MMC in the treatment of pterygia.
objectiveThe objective of this case report is to report the successful use of preoperative subconjunctival injection of low-dose (0.02%) MMC one month before bare sclera excision of a multirecurrent pterygium, as well as the concomitant intraoperative application of MMC to the conjunctival fornix of the same eye after the excision of an associated symblepharon. CASE REPORT: A 31-year-old man from Kano, Northern Nigeria, presented to the eye clinic with a recurrent pterygium associated with an upper lid symblepharon in his right eye. He has had five previous pterygium excisions, with the last surgery involving conjunctival autografting and subconjunctival steroid injection. He was subsequently given 0.1 mL of 0.02% MMC as a subpterygial injection; one month later he had an alcohol-assisted bare sclera pterygium excision and a symblepharolysis with the intraoperative application of 0.02% MMC for 1 minute to the upper conjunctival fornix. Except for a Tenon granuloma that was simply excised, there has been no recurrence or other complications up to a year after surgery.
conclusionAs a cheaper and technically easier treatment option, a preoperative subconjunctival MMC injection followed by bare sclera pterygium excision was found to be effective in this patient with a recurrent pterygium. As at one-year follow-up, low-dose preoperative MMC a month prior to surgery also appeared safe and effective when combined with its intraoperative application to the conjunctival fornix for the treatment of associated symblepharon.
