PURPOSE To study the effect of topical application of mitomycin C on enhancing the efficacy of needling in the management of bleb failure. PATIENTS AND METHODS Thirty-six eyes of 32 consecutive patients with an intraocular pressure over 21 mmHg, without bleb or with a thick, flat bleb after the second postoperative month after trabeculectomy, were included in the study. Needling with mitomycin C was performed in the other 18 eyes with bleb failure (group A) and needling without antimetabolite was performed in 18 eyes (group B). Topical application of mitomycin C (0.4 mg/mL) with a microsponge over the conjunctiva at the failed bleb for 5 minutes (group A) was performed; after irrigation, the needling procedure was the same in both groups. A 30-gauge needle was used to perforate the area of subconjunctival and subscleral fibrosis and to reestablish flow; conjunctival puncture was at least 7 mm away from the bleb and no sutures were taken after needling. Follow-up was performed for 1 year after needling. RESULTS Overall, 55 needling procedures were performed; needling was done twice in 17 eyes in group B, whereas only 2 eyes needed more than 1 needling procedure in group A. The difference was statistically highly significant, and the mean follow-up was 8.9 ± 3.7 months. Mean intraocular pressure was 28.9 ± 4.2 mm Hg and 27.8 ± 4.7 mm Hg in group A and group B respectively before any intervention; this decreased to a mean of 19.8 ± 2.7 mm Hg and 20.5 ± 4.8 mm Hg respectively without medication after 6 months of last needling. Complications included diffuse corneal punctate epitheliopathy lasting for 2 to 3 weeks (2 eyes in group A), subconjunctival hemorrhage (3 eyes in each group), and hyphema (2 eyes in each group). CONCLUSIONS Topical application of mitomycin C with needle revision seems to be an extremely effective way to revive failed filtration surgery. The incidence of complications related to mitomycin C was minimal.

Needling augmented with topical application of mitomycin C for management of bleb failure.

As we approach a new normal in post-Covid-19 pedagogy, we need to consider blended learning (BL) as a significant contribution to precautionary and preventive actions for containing the spread of Covid-19. This paper provides a framework to recognize transformation to a new normal by: a) reviewing the history of BL associated with its models and design options; b) presenting general characteristics of BL in a matrix of place, distance, and technology; and c) analyzing scenario planning and strategies for reopening academic institutions. Based on the BL continuum and health and safety conditions resulting from the pandemic, the study first proposed a scenario planning framework. Second, it developed a classification framework of BL addressing its continuum, models, and learning theories via a smart learning environment. Finally, the study proposed a conceptual matrix of BL that considers health and safety conditions resulting from the Covid-19 pandemic.

Blended Learning: The New Normal for Post-COVID-19 Pedagogy

Purpose : To compare the efficacy of preoperative local injection of mitomycin C (MMC) to intraoperative application of MMC in the prevention of pterygium recurrence after surgical removal. Materials and Methods : Seventy eyes of 70 patients with primary pterygia were randomly allocated to two groups. The first group (Group A, 35 eyes) received 0.1 ml of 0.15 mg/ml of subconjunctival MMC injected into the head of the pterygium 24 h before surgical excision with the bare sclera technique. The second group (Group B 35 eyes) underwent surgical removal with the bare sclera technique with intraoperative application of MMC (0.15 mg/ml) over bare sclera for 3 min. The study was performed between March 2007 and December 2008, and follow up was performed for 1 year postoperatively. Differences between frequencies in both groups were compared by the Chi-square test or Fisher exact test. Differences between means in both groups were compared by Student's t-test. P Results : The rate of pterygium recurrence was 5.70% in Group A and 8.57% in Group B at 1 year postoperatively (P>0.05). Postoperatively, scleral thinning occurred in one eye in each group that resolved by 5 months postoperatively. No serious postoperative complications occurred in either group. Conclusion : Preoperative local injection of 0.15 mg/ml MMC is as effective as intraoperative topical application of 0.15 mg/ml MMC for preventing pterygium recurrence after surgical removal.
