Purpose: To correlate the central subfield thickness (CST) measured by Cirrus TM SD-OCT with best-corrected visual acuity (BCVA) and structural changes in diabetic macular edema (DME). Methods: The transversal study evaluated 200 patients with non-proliferative dia betic retinopathy (NPDR) and selected 55 eyes with DME between January, 2010 and April, 2011. Spectral domain OCT was performed in patients with type 2 diabetes and DME. CST and BCVA were correlated with the edema morphology and the ELM (external limiting membrane) integrity. Statistical tests were applied to validate the results. Results: There was no difference between genders in the NPDR classification. 47.3% of the patients showed moderate NPDR. The CST average for male was of 393.58 µm and 434.16 µm for female, with no statistically significant difference. The patients with continuous ELM showed lower CST average (368.73 µm) than those with disrupted ELM (521.43 µm). There was a strong correlation between the macular volume and CST (59.63%), but poor correlation between age and CST (2.9%). Also, there was a significant difference between the average CST and the type of macular edema. Patients with serous detachment showed higher CST average (488.71 µm) than those with cystoid macular edema (CME) and diffuse edema. Patients with severe NPDR showed higher CST average (491.45 µm), if compared to mild and moderate NPDR. Cystoid macular edema was the most common type of edema (49.1%) and showed the worse VA. Patients with disrupted ELM showed worse BCVA. Patients with higher CST showed worse BCVA. There was a significant difference between the CST average of the case group (407.6 ± 113,1 µm) and the control group (diabetic patients without DME: 252 ± 12.5 µm). There was also a significant difference in the BCVA variables and macular volume between case and control groups. Conclusion: The study suggests that the CST of diabetic patients with edema is higher than the control group, the increase in CST of diabetic patients with edema leads to worsening of BCVA and macular volume. Continuous ELM showed lower CST average, and the serous detachment showed higher CST average. Cirrus TM proved to be an important tool in the DME evaluation.
This study suggests that antifibroproliferative therapy with intraoperative sponge 5-FLU is effective and safe. Its use may be a useful adjunct in primary pterygium surgery.

RESUMOObjetivo: Avaliar a eficácia e a segurança do uso intraoperatório da mitomicina C (MMC) no tratamento cirúrgico do pterígio. Métodos: Estudo de 102 pacientes (204 olhos) divididos em dois grupos, e submetidos a exérese do pterígio com rotação de retalho conjuntival e aplicação intra-operatória de MMC 0,02% por 2 minutos e a mesma técnica utilizando solução salina a 0,9% (grupo controle). Os pacientes foram avaliados no 1º, 7 º, 21º, 30º, 60º e 90º dia de pós-operatório (PO). Resultados: Houve um maior acometimento do pterígio no sexo feminino (59,9%). A idade variou entre 33 a 69 anos. As recidivas (9) no no grupo MMC foram identificadas no 90º PO. No grupo controle foi identificado 18 recidivas em 60 dias de pós-operatório. As complicações identificadas no grupo da MMC foram: ceratite, edema de pálpebra, deiscência de sutura, isquemia, granuloma, corneal dellen e simbléfaro. Conclusão: O uso da MMC foi útil na redução da taxa de recidiva do pterígio, comparada ao uso de solução salina, porém seus efeitos deletérios devem sempre ser avaliados.Descritores: Mitomicina/administração & dosagem; Pterígio/cirurgia; Conjuntiva; Granuloma; Cornea ABSTRACTPurpose: Measure of efficacy and the security of intraoperative of mitomycin C (MMC) in the pterygium surgery. Methods: Realized prospective analysis of 102 patients (204 eyes) divided in two groups submitted intraoperative MMC 0.02 % for 2 minutes or saline solution 0.9%. The patients were available in 1º, 7 º, 21º, 30º, 60º and 90º days of postoperative. Results: The pterygium was more prevalence in females (58,33%). The age various 33 to 69 years. The recidive (9) was in the 90º PO in the group of MMC. In the control group was identificated two recidives in 60 days. The complications found in MMC group were: ceratitis, lips edema, dehiscence of suture, ischemia, granuloma, corneal dellen and simblefaro. Conclusion: The use of MMC was useful in reducing the rate of recurrence in pterygium compared to the use of saline solution, but its harmful effects must always be evaluated.
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.
