Resumo: | Keratoconus is a disease characterized by the progressive bulging and thinning of the cornea, resulting in loss of visual acuity and irregular astigmatism. The disease is the principal cause of corneal transplants in Brazil. Although there are no therapies available that offer a cure, there are treatments capable of preventing its progression. Crosslinking (CXL) is the most recent treatment in this area, that consists in a procedure that uses ultraviolet A (UVA) radiation and riboflavin. Our study involved a retrospective analysis of 280 eyes submitted for CXL treatment. Measurements were undertaken of corneal topography, topography astigmatism, and variables such as allergy, blepharitis, and contact lens use before CXL. We analyzed preoperative 1 (1-182 days), postoperative 2 (183-364 days), postoperative 3 (365-546 days) and postoperative 4 (547 days and beyond). The mean age that went through the procedure was 18,8 years ± 4,4 years. The analysis between groups over and under 18 years had no significant difference in stabilization of the disease. There was a ratio of two men for one woman that realized the procedure (p <0,0001). Males had higher values of Kmax in the preoperative period (p=0,0091), as well as greater stabilization in the postoperative 3 (p= 0,028). It was found that patients with allergies tended to be younger when CXL was performed (allergic: 18,2 years ± 4,16 vs. non-allergic 19,5 years ± 4,55; p = 0,0039). Blepharitis and use of contact lenses prior to CXL did not influence the outcome of the procedure. Although it was not statistic significant, topography astigmatism had a reduction specially in postoperative 3. Parameters K1, K2 and Kmax had a significant reduction in distinct moments of postoperative. Therefore, we concluded that Crosslinking is a procedure statistically effective and secure, reinforcing its role in stabilizing keratoconus. |

Sua importância é embasada principalmente no fato de ser a principal causa de transplantes de córnea no Brasil. Não há terapêuticas disponíveis que assegurem a cura, entretanto, existem métodos capazes de impedir a progressão, sendo o Crosslinking (CXL) – procedimento realizado com luz ultravioleta A (UVA) e riboflavina – a terapêutica mais recente nesse ramo. O nosso estudo envolveu uma análise retrospectiva de 280 olhos submetidos a CXL, com medidas de topografia corneana e astigmatismo topográfico, assim como das variáveis alergia, blefarite, e uso de lentes de contato previamente ao CXL. Foram analisados pré-operatório, pós-operatório 1 (1-182 dias), pós-operatório 2 (183-364 dias), pós-operatório 3 (365-546 dias) e pós-operatório 4 (maior ou igual a 547 dias). A idade média de realização do procedimento foi de 18,8 anos ± 4,4 anos, e quando comparados grupos de idade acima e abaixo de 18 anos, não houve diferença significativa na estabilização da doença. O sexo masculino obteve uma proporção de 2:1 quando comparado com o sexo feminino (p <0,0001). Além disso, o sexo masculino demonstrou maiores valores de Kmáx no pré-operatório (p=0,0091), assim como maior estabilização no pós-operatório 3 (p= 0,028). Constatou-se que pessoas alérgicas são mais jovens ao realizar o CXL (alérgicos: 18,2 anos ± 4,16 vs. não alérgicos: 19,5 anos ± 4,55; p = 0,0039). A presença de blefarite e o uso de lentes de contato prévio ao CXL não influenciaram no resultado do procedimento. O astigmatismo topográfico, embora sem significância estatística, apresentou redução especialmente no pós-operatório 3. As variáveis K1, K2 e Kmáx obtiveram redução significativa dos valores topográficos em momentos distintos de pós-operatório. Dessa forma, concluiu-se que o Crosslinking é um procedimento estatisticamente eficaz e seguro na melhora topográfica do ceratocone.Universidade PositivoBrasilMedicinaUPMartini, Milena Binhame Albinihttp://lattes.cnpq.br/1092078843737955Ferraris, Amanda LiberatoreNagazava, Fernanda AkemiVale, Mariana Miyazaki SolanoFontanella, Mateus Gomes2022-06-01T18:22:50Z20212022-06-01T18:22:50Z2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisapplication/pdfhttps://repositorio.cruzeirodosul.edu.br/handle/123456789/3841porinfo:eu-repo/semantics/openAccessreponame:Repositório do Centro Universitário Braz Cubasinstname:Centro Universitário Braz Cubas (CUB)instacron:CUB2022-06-01T18:25:30Zoai:repositorio.cruzeirodosul.edu.br:123456789/3841Repositório InstitucionalPUBhttps://repositorio.brazcubas.edu.br/oai/requestbibli@brazcubas.edu.bropendoar:2022-06-01T18:25:30Repositório do Centro Universitário Braz Cubas - Centro Universitário Braz Cubas (CUB)false |
