A plethora of ocular surface manifestations in a multidisciplinary ocular graft-versus-host disease unit.

To describe the experience in a recently created ocular graft-versus-host disease unit in a tertiary hospital and to detail ocular surface features and complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This retrospective study included all patients who underwent allo-HSCT, with or without chronic GVHD and were being monitored in the Hematopoietic Stem Cell Transplantation Unit in the UNICAMP Clinical Hospital (Campinas, Sao Paulo, Brazil) from 2015 to 2020. Patients were concomitantly evaluated by hematology and ophthalmology teams of the Ocular GVHD Unit. Hematologists performed a comprehensive systemic evaluation searching and grading mouth, skin, lungs, gastrointestinal tract, liver and genitalia GVHD. While ophthalmologists evaluated ocular symptoms through specific questionnaire (Ocular Surface Disease Index-OSDI) and a protocol of distinct ocular surface parameters for dry eye disease (1) and ocular complications, which encompassed meniscometry, non-invasive tear break-up time (NITBUT) measurement, conjunctival hyperemia quantification, meibography, fluorescein and lissamine staining and Schirmer's test. Patients were diagnosed with chronic GVHD using the National Institutes of Health (NIH) Consensus Criteria for Chronic Graft-versus-Host Disease. The International Chronic Ocular GVHD Consensus Group (ICOGCG) score was obtained at the onset of ocular disease presentation or afterwards. A total of 82 patients underwent allo-HSCT (97.6% full matched and 2.4% haploidentical), mainly for cases of leukemia and 73.2% had chronic GVHD. Mean onset time for chronic GVHD was 232 ± 7.75 days. The mouth, skin, and eyes were the main organs involved (63%, 50%, and 48%, respectively). Symptom scores and all ocular surface parameters differ in patients with and without chronic GVHD and along different timepoints of the follow-up. Ocular complications mostly involved were severe DED and meibomian gland dysfunction, conjunctival scarring, cataract and infections resulting in keratitis and corneal perforation. As therapeutic strategies, 73% patients received preservative-free lubricants, 27% autologous serum, 48% topical steroids, 27% oral tetracycline derivatives, 22% mucolytic eye drops and 3 patients needed bandage contact lens. Ocular GVHD is a complex and challenging disease with varied manifestations, resulting in a broad range of ocular test endpoints, and inconsistent treatment responses. The main ocular presentations were dry eye, meibomian gland dysfunction and cataracts. The therapeutic approach often involves topical steroids and autologous serum tears. It is important to monitor these patients closely, so the ocular GVHD Unit may improve the care, providing prompt identification of ocular manifestations and faster treatment of complications.

The contact lens dry eyes questionnaire (CLDEQ-8) validation and ocular surface dysfunction among soft contact lens wearers / Validação do questionário de olho seco em lentes de contato (CLDEQ-8) e a disfunção de superfície ocular em usuários de lente de contato

ABSTRACT Purpose: To translate and validate the Contact Lens Dry Eyes Questionnaire (CLDEQ-8) to Portuguese language and to describe the impact of soft contact lenses on the ocular surface. Methods: We conducted a descriptive transversal study with the aim to: (1) translate and validate the CLDEQ-8 questionnaire to Portuguese language and (2) apply the CLDEQ-8 to a group of contact lens wearers along with a broad evaluation of the impact of soft contact lens on the ocular surface. The evaluation of the impact of soft contact lens was performed for a study population of 81 subjects, categorized in two groups: Group A: 61 contact lens wearers and Group B (control): 20 noncontact lens wearers. The study exclusion criteria were rigid contact lens wear, systemic or ocular diseases, the use of medications predisposing to ocular surface damage, and previous ocular surgeries. Results: For the CLDEQ-8 questionnaire translation and validation, Kappa agreement values were ³0.7 in all questions, implying a good agreement between the Portuguese and English language versions. Considering the ocular surface evaluation of the subjects, all parameters differed in Soft contact lens wearers when compared with the controls (p<0.05), except in those related to tear volume, such as the tear meniscus height and Schirmer test. Conclusions: This study provided a translated and validated Portuguese version of CLDEQ-8 questionnaire, which represents an important tool for the evolution of contact lens wearers. The broad evaluation of the ocular surface revealed an association between soft contact lens wearing and ocular surface disturbances.

RESUMO Objetivo: Traduzir e validar o questionário de olho seco e lentes de contato (CLDEQ-8) para o português e descrever o impacto das lentes de contato gelatinosas na superfície ocular. Métodos: Estudo transversal e descritivo com o objetivo de (1) traduzir e validar o CLDEQ-8 para o português e (2) aplicar o CLDEQ-8 em um grupo de usuários de lentes de contato, juntamente com uma ampla avaliação do impacto das lentes gelatinosas na superfície ocular. A avaliação do impacto das lentes gelatinosas foi realizada em uma amostra composta por 81 indivíduos, divididos em dois grupos: 61 usuários de lente de contato (Grupo A) e um grupo controle de 20 não usuários (Grupo B). Como critério de exclusão: usuário de lentes de contato rígidas, doenças sistêmicas ou oculares prévias, uso de medicamentos que podem causar danos a superfície ocular e cirurgias oculares prévias. Resultados: Para a tradução e validação do questionário CLDEQ-8, os valores de concordância Kappa foram iguais ou superiores a 0,7 em todas as perguntas, o que implica em uma boa concordância entre as versões em português e inglês. Considerando a avaliação da superfície ocular dos sujeitos, todos os parâmetros diferiram nos usuários de lente de contato em comparação com os controles (com p<0,05), exceto naqueles relacionados ao volume lacrimal, como altura do menisco lacrimal e teste de Schirmer. Conclusões: Este estudo forneceu uma versão traduzida para o português e validada do questionário CLDEQ-8, que representa uma importante ferramenta na avaliação de usuários de lente de contato. A avaliação da superfície ocular realizada demonstra a relação entre o uso de lentes de contato gelatinosas e os distúrbios da superfície ocular.
