OBJECTIVES:The aim of this study was to report the type and frequency of ocular manifestations in Brazilian psoriatic arthritis patients.METHODS:We conducted a cross-sectional study in a Brazilian tertiary hospital. The test group included 40 patients who had psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis. A control group of 40 individuals was matched for age and gender. All of the patients underwent ophthalmic evaluation, which included best-corrected visual acuity, slit lamp and fundus examinations, and dry eye diagnostic tests (Schirmer I, tear break-up time and rose bengal). Demographic parameters were also evaluated.RESULTS:The mean age of the patients was 53.9±13.1 years; the mean disease duration was 8±10.5 years. Most of the patients were women (60%), and the majority had polyarticular disease (57.5%). Several ocular abnormalities were found, including punctate keratitis, pinguecula, blepharitis, pterygium, cataract, glaucoma, uveitis, and retinal microvascular abnormalities. There were no significant differences in the rates of these abnormalities compared with the control group, however. The Keratoconjunctivitis sicca and dry eye diagnostic tests were more often positive in the patients with psoriatic arthritis than in the control group.CONCLUSIONS:In this study, keratoconjunctivitis sicca was the most common ocular finding related to psoriatic arthritis. Therefore, we recommend early ophthalmologic evaluations for all psoriatic arthritis patients who complain of eye symptoms.
RESUMOObjetivo: Correlacionar área do disco óptico com parâmetros geométricos e biomecânicos da córnea. Métodos: Estudo retrospectivo nos arquivos de pacientes do Instituto de Olhos Renato Ambrósio a fim de se identificar os pacientes que realizaram exames HRT (Heidelberg Retina Tomography), Pentacam e ORA. A retinografia digital foi revisada de modo a se classificar na escala DDLS (Disc Damage Likelihood Scale).Resultados: 244 olhos de 122 pacientes (75 mulheres) foram incluídos no estudo. A média de idade foi de 47,2 anos (de 8 a 97 anos, desvio padrão de 21,7). Não houve correlação significante entre área do disco e nenhuma das medidas de PIO (IOPg, IOPcc). Encontrou-se uma relação negativa significativa com CRF (r=-0,1337, p=0,0263). A relação com histerese foi também negativa (-0,1123), mas o valor p foi maior que 0,05 (0,0625). Não houve correlação significante entre área do disco e progressão paquimétrica mínima ou média. Entretanto, observou-se correlação significante e positiva entre a área do disco e astigmatismo corneano (Delta K), sendo de 1,15 (p=0,0129). Conclusão: Existe uma correlação negativa entre a área do disco óptico e os parâmetros biomecânicos e estruturais da córnea. Tal correlação pode ser parte da explicação da córnea ser um fator de risco para maior susceptibilidade do nervo óptico para neuropatia glaucomatosa.
