Efeito terapêutico do crosslinking corneal na ceratite infecciosa

Abstract: Purpose:To evaluate the effect of corneal crosslinking (CXL) RESUMOObjetivo: Avaliar o efeito do crosslinking (CXL) no tratamento de ceratite infecciosa, resistente ao tratamento clínico, e investigar a relação com o agente etiológico. Métodos: Foram incluídos 11 pacientes com diagnóstico de ceratite infecciosa de etiologia bacteriana (sete olhos) e fúngica (quatro olhos) na Fundação Altino Ventura (FAV) no período de outubro de 2011 a maio de 2012. Os pacientes incluídos estavam em uso de colírios há pelo … Show more

“…They also showed a low success rate in fungal infections consistent with our findings in which from the four eyes that needed surgery due to imminent perforation, three (75%) had a fungal isolate by culture. This finding is consistent with other studies [31][32][33][34] where bacterial keratitis cases show improvement after PACK-CXL treatment, whereas fungal keratitis show less or no improvement at all, 35 like in our study, where the 3 cases with a fungal isolate had a torpid evolution and needed urgent surgery to avoid organ loss, which unfortunately could not be prevented in one case. Nevertheless, there are studies that report a high success rate for fungal ulcers.…”

“…On the other hand, the positive outcomes obtained in this study are opposed by others as Prajna NV et al reported that patients who underwent CXL were no more likely to re-epithelialize by 3 weeks or 3 months, they had no improvement in infiltrate or scar size, and they even had worse final visual acuity [ 42 ]. Also, some published studies reported that the PACK-CXL procedure is not effective in managing fungal keratitis [ 43 , 44 ]. Their negative results could be attributed to the fact that a sufficient concentration of riboflavin in corneal stroma is crucial to get a biomechanical effect of corneal CXL [ 45 , 46 ].…”
