Authors present here an in vitro model system for the treatment of post-trabeculectomy patients. The study is aimed at the evaluation of different drugs in a mouse fibroblast model.\u0000\u0000\u0000METHODS\u0000The antifibrotic activity of Cyclosporin A, Interferon 2alpha, 5-Fluorouracyl was investigated on 3T6 cells in culture. Cell viability and proliferation was assessed after drug treatment. Molecular analysis of DNA degradation was evaluated by means of radioactive labeling and gel electrophoresis.\u0000\u0000\u0000RESULTS\u0000The three drugs were shown to affect cell proliferation and viability in a differential fashion. However, only Cyclosporin A was able to control cell proliferation, inducing apoptosis. This phenomenon was reduced by supplementation of trolox, a compound known to inhibit programmed cell death. These results strongly suggest that this model system might be useful as a test of pharmacological functionality.\u0000\u0000\u0000CONCLUSION\u0000A rapid and efficient model system is described for the assessment of cell viability and proliferation after treatment with agents of potential pharmacological use. Cyclosporin A induces a significant apoptosis. This is important for the negative control of fibrotic degeneration in post-trabeculectomy that is required for successful surgery in glaucoma patients. Therefore, Cyclosporin A might become a clinically interesting drug for the antifibrotic treatment of post-trabeculectomy.","PeriodicalId":7152,"journal":{"name":"Acta ophthalmologica Scandinavica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86277345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IOP was measured every third hour starting at 9 a.m. with a calibrated Goldmann tonometer; one week later, a similar set of measurements was obtained with Ocuton-S self tonometry by the patients. One week later still, ultrasound corneal pachymetry was performed at the same hours.\u0000\u0000\u0000RESULTS\u0000Overall IOP (24-hour mean) did not differ significantly between the different measuring techniques (ANOVA, p = 0.74), but the IOP differed in a statistically significant manner around the clock (ANOVA, p = 0.00006). The mean Goldmann tonometric readings were up to 2.8 mmHg lower than the Ocuton-S values during the daytime (9 a.m. to 9 p.m.), however, during the night (12 midnight to 6 a.m.) mean IOP measured with Goldmann tonometry was 2.2 to 3.3 mmHg higher than the corresponding average of the self tonometry readings. There was a statistically significant interaction between the type of tonometry and the time of the measurement (p = 0.0007). Central corneal thickness (CCT) showed a significant change during the 24-hour period (p = 0.000001).\u0000\u0000\u0000CONCLUSION\u0000IOP shows a different diurnal curve when measured with the Goldmann tonometer and with the Ocuton-S applanation self tonometer. The instruments' readings might be influenced in different ways by the diurnal changes of the corneal thickness. Since Ocuton-S self tonometry underestimates the IOP in the early morning period, a careful evaluation is necessary when nocturnal and early morning IOP elevation is investigated with this technique.","PeriodicalId":7152,"journal":{"name":"Acta ophthalmologica Scandinavica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90530645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
