Resumo: | Introduction: Our purpose was to evaluate the effect of eye rubbing discontinuation on the epithelial thickness profile by spectral-domain AS-OCT (anterior segment optical coherence tomography) in allergic children with no tomographic sign of corneal ectasia. Methods: Right-handed boys (average age 11.2 years, 8-12 years) with history of eye rubbing and relatively normal Pentacam (Oculus; Wetzlar, Germany) exams were recruited for the study. Patients were evaluated using AS-OCT (Zeiss Cirrus 5000 HD-OCT, Carl Zeiss Meditec, Dublin, CA, USA) at the baseline and after 8 weeks of treatment. Treatment included education to avoid eye rubbing and preservative free 0.25 mg/mL topical ketotifen. Epithelial thickness (ET) and full corneal thickness (CT) parameters were compared with paired non-parametric Wilcoxon (signed-ranked) test. A p-value lower than 0.05 was considered for statistical significance. Results: Twenty-five boys completed the protocol. No eyes had tomographic criteria for keratoconus (Belin-Ambrosio Deviation Value < 1.22). Minimum epithelial location moved from the inferotemporal to superotemporal octant after treatment. The differences between minimum and maximum epithelial thickness (-2.8 µm vs -5.2 µm; p<0.01) and between nasal and temporal octants (N-T) (3.1 µm vs 1.4 µm; p<0.01) were higher at the baseline. The difference between inferior and superior (I-S) octants (1.1 µm vs 2.7 µm; p<0.01) was lower at the baseline. Conclusion: AS-OCT analyses reveal epithelial remodeling after allergy treatment and eye rubbing discontinuation, with marked inferotemporal thickening. The importance of educating against eye rubbing and treating allergy should consider its importance on corneal epithelial remodeling. Further studies should include patients with corneal ectatic conditions and to explore other clinical measurements such as biomechanical assessment. |

Introdução: O nosso objetivo foi fazer a avaliação do efeito de parar de coçar os olhos no perfil epitelial da córnea através de análise com tomografia de coerância ótica do segmento anterior (AS-OCT) em crianças atópicas sem sinais tomográficos de ectasia. Métodos: Rapazes dextros (idade média 11,2 anos) com hábito de coçar os olhos e tomografia de córnea (Pentacam, Oculus; Wetzlar, Germanh) sem alterações foram incluídos. Foi realizado AS-OCT (Zeiss Cirrus 5000 HD-OCT, Carl Zeiss Meditec, Dublin, CA, USA) na baseline e após 8 semanas de tratamento com cetotifeno tópico sem conservantes (0,25 mg/mL). A espessura epitelial e a espessura total da córnea foram comparadas através de testes não paramétricos emparelhados de Wilcoxon. Um p-value inferior a 0,05 foi considerado estatisticamente significativo. Resultados: Vinte e cinco rapazes completaram o estudo. Nenhum olho apresentou critérios tomográficos de ectasia (Belin-Ambrosio Deviation Value < 1,22). A espessura epitelial mínima deslocou-se da região inferotemporal para a região inferotemporal após o tratamento. As diferenças entre a espessura epitelial minima e máxima (-2,8 µm vs -5,2 µm; p<0,01) e entre as regiões nasal e temporal (N-T) (3,1 µm vs 1.4 µm; p<0,01) foram superiores na baseline. A diferença entre as regiões inferior e superior (I-S) (1,1 µm vs 2,7 µm; p<0,01) foi inferior na baseline. Conclusão: A análise do epitélio da córnea atráves de OCT do segmento anterior revelou um espessamento inferotemporal após tratamento antialérgico e consequente descontinuação do ato de coçar os olhos. Estes resultados parecem ilustrar o dano deste ato repetido sobre a córnea e salientam a importância de educação da população acerca dos riscos associados ao mesmo.Ajnet2021-12-31T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.48560/rspo.25443eng1646-69501646-6950Loureiro, TomásRodrigues-Barros, SandraCarreira, Ana RitaMoraes, FilipeCarreira, PedroVide Escada, AnaCampos, PaulMachado, InêsCampos, NunoAmbrósio Jr, Renatoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-22T17:06:16Zoai:ojs.revistas.rcaap.pt:article/25443Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:01:47.255214Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
