Pterygium is a triangular encroachment of bulbar conjunctiva on to the cornea known for high recurrence rate. Various adjunctive measures were used to reduce the recurrence rate. Nowadays thoughutureless and glue-free conjunctival autograft has been encouraged for treating primary pterygium yet sutured conjunctival autograft is also extensively performed. To assess and compare graft stability, complication profiles and patient comfort in sutureless glue-free and sutured conjunctivo limbal autograft in pterygium surgery and to assess postoperative improvement in parameters associated with visual defects due to pterygium.Sutured conjunctival autograft were done in 25 patients (group A), and sutureless and glue-free conjunctival autograft was done in 25 patients (group B). Postoperative discomfort was assessed for 90 days during which graft related complications and recurrence if any were noted. Pre and postoperative parameters associated with visual defects due to pterygium were also compared. Total number of patients who developed postoperative complications was 22(88%) in Group A and 15(60%) patients in Group B. Number of patients with postoperative discomfort was significantly less in group B after 1 week and almost nil on 30 day. In Group A one patient graft unstability and in Group B two patients showed graft unstability.Sutureless glue free auto conjunctivo limbal stem cell transplantation showed significantly better patients comfort and decreases suture related complications.
PURPOSE. To investigate the relationship between supplementary consumption of the oxidants calcium and iron and caffeine and the prevalence of glaucoma. METHODS. This cross-sectional study included 3833 participants 40 years of age, who reported a presence or absence of glaucoma. Participants were interviewed regarding the use of dietary supplements and antacids during the preceding 30-day period. Data pertaining to the supplementary intake of calcium, iron and caffeine was aggregated and divided into quintiles. Information regarding the presence or absence of glaucoma and demographics, comorbidities, and health-related behavior was obtained via interview. RESULTS. Participants who consumed 800 mg/d of supplementary calcium or 18 mg/d of supplementary iron had significantly higher odds of having been diagnosed with glaucoma than did those who had not consumed supplementary calcium or iron, after adjustment for potential confounders. Concurrent consumption of both calcium and iron above these levels was associated with still greater odds of having been diagnosed with glaucoma. Compared with participants whose cumulatively updated total caffeine consumption was <125 mg/day, participants who consumed ≥500 mg/day had a trend toward increased risk of glaucoma. CONCLUSIONS. These results suggest that there may be a threshold intake of iron, calcium and caffeine above which there is an increased risk of development of glaucoma. Prospective longitudinal studies are needed, to assess whether oxidant intake is a risk factor for development and progression of glaucoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
