PURPOSE: To investigate the efficacy of bleb needle revision with high-dose mitomycin C in reviving failed filtering blebs after 1 year. PATIENTS AND METHODS: We reviewed the charts of 44 patients with one eye that had undergone bleb needle revision with a mixture of 0.1 mL of mitomycin (0.4 mg/mL) mixed with 0.1 mL of non-preserved 1% lidocaine. At least 12 months of follow-up were required. A successful bleb needle revision was defined as one that did not require a subsequent needling, glaucoma surgery, or medication to reach an intraocular pressure (IOP) greater than 4 mm Hg but less than 22 mm Hg. A qualified success was defined as a successful bleb needle revision that required subsequent needling or medication. RESULTS: The bleb needle revision with high-dose mitomycin was a success or qualified success after 12 months in 28 patients or 64% (95% confidence interval, 50% to 78%). The baseline IOP in these patients was 26.7 +/- 8.2 mm Hg (range 15 to 48 mm Hg) using an average of 1.5 +/- 1.5 glaucoma medications. The IOP after 1 year was 13.6 +/- 4.0 (range 6 to 21 mm Hg) with an average of 0.5 +/- 0.8 medications. Of 44 patients, 17 (39%) were successes and 11 (25%) were qualified successes. CONCLUSION: Bleb needle revision with high-dose MMC was effective in reducing the IOP in 64% of eyes with a failed filtering bleb with minimal long-term complications.

An ophthalmic follow-up comprised 88 children aged 7-10 years who had regular screening for retinopathy of prematurity (ROP) after their pre-term delivery 1982-84. Mean values of birth weight and gestational age in the 88 were 1467 g and 31 weeks. Out of 28 with early evidence of ROP four had progressed to bilateral blindness; the remaining 24 had at least a corrected visual acuity of 0.4 at disposal. The corrected median binocular acuity for all 88 was 0.95; however, the cumulated frequency curve was significantly below a previously stated norm in full-terms. The same conclusion was valid for single eye vision. Within the material, the visual score of the 28 with early ROP was significantly lower than in the remaining 60 subjects. Ophthalmoscopy often showed tortuosity of vessels, but no specific central retinal or optic nerve lesion to explain the slight general depression of visual acuity, and opacities of media contributed in only two subjects. It is concluded, that very preterm delivery generally influences the potential for developing full visual acuity, also in individuals without evidence of early ROP. Evidence of CNS-damage negatively influenced visual acuity score.
