Evaluation of ocular involvement in patients with Hansen's disease.

Hansen's disease (HD) belongs to the group of neglected diseases and can cause physical deformities and disabilities, in addition to leading to social discrimination. Ocular involvement in HD is estimated at 70-75% worldwide. About 10-50% suffer from severe ocular symptoms and loss of vision occurs in approximately 5% of cases. Ocular changes may persist or worsen even after patients are considered cured and it is necessary to better understand these conditions in order to determine the need for additional public policies. The objective of this study was to identify the prevalence of ocular involvement in patients with HD at two specialist referral centers for treatment of the disease. A cross-sectional study was conducted with ophthalmological evaluations of patients with HD from June 2017 to June 2018. Diagnostic ocular findings, corrected visual acuity, and refractive error were described. Findings were correlated with patients' clinical and epidemiological variables. A total of 86 patients were evaluated, with a mean age of 50.1 years, predominantly males (59.3%), and with multibacillary HD (92%). The prevalence of ophthalmologic changes was 100% and the most common were dysfunction of the Meibomian glands (89.5%) and dry eye syndrome (81.4%). Cataracts were observed in 22 patients (25.6%), but best corrected visual acuity was normal or near normal in 84 patients (97.7%) and there were no cases of bilateral blindness. Patients with some degree of physical disability had more ophthalmological alterations, involving both the ocular adnexa (p = 0.03) and the ocular globe (p = 0.04). Ocular involvement is common in patients with Hansen's disease, reinforcing the importance of ophthalmologic examination in the evaluation and follow-up of these patients.

Congenital and developmental cataract: axial length and keratometry study in Brazilian children.

PURPOSE: To evaluate the ocular axial length (AL) and keratometry (K) in Brazilian children with congenital/developmental cataract, assess the differences and evolution of AL and K according to age, and establish functional models of AL and K as function of age. METHODS: Children with congenital/developmental cataract aged 1.5 months old to 8 years old and no other ocular diseases were included. All eyes with unilateral cataract, the left eyes from children with bilateral cataracts, and healthy eyes from children with unilateral cataract were analyzed. After the administration of anesthesia, K was measured with a portable automatic keratometer, and AL was measured with a contact biometer. Cataract surgery was performed immediately after the measurements were taken. The data were statistically analyzed, and a linear regression with an age logarithm was used to model the relationship. RESULTS: Forty-four eyes with cataract were included in this analysis, comprising 15 eyes with unilateral cataract and 29 left eyes from children with bilateral cataracts. The mean age was 27.3 months with a mean AL of 20.63 ± 2.11 mm and a mean K of 44.94 ± 2.44 D. The K value was significantly steeper and the AL value was significantly shorter in younger children (P< 0.001). No significant differences were found neither between eyes with unilateral and bilateral cataracts nor between eyes with unilateral cataract and their corresponding healthy eyes (P >0.05). CONCLUSION: The values of K and AL significantly change with age, especially during the first 6 months of life. A linear functional relationship between K and AL with the logarithm of age and between K and AL was established.

RESUMO Objetivo: Avaliar o comprimento axial (AL) e a ceratometria (K) de olhos de crianças brasileiras com catarata congênita/desenvolvimento, analisar diferenças e evoluções de acordo com a idade e estabelecer modelos funcionais de comprimento axial e ceratometria em função da idade e entre eles. Métodos: Crianças com catarata congênita/desenvolvimento com idade de 1,5 meses a 8 anos de idade e sem outras doenças oculares foram incluídas. Todos os olhos com catarata unilateral, o olho esquerdo de crianças com catarata bilateral e o olho sadio de crianças com catarata unilateral foram analisados. Após a administração de anestesia, a ceratometria foi obtida com um ceratômetro automático portátil e o comprimento axial medido com um biômetro de contato. Em seguida, a cirurgia de catarata foi realizada. Os dados foram analisados estatisticamente, a regressão linear com o logaritmo da idade foi utilizado para modelar os relacionamentos. Resultados: Todos os olhos com catarata unilateral (n=15) e um olho selecionados aleatoriamente a partir dos casos bilaterais (n=29) foram incluídos na análise (total= 44 olhos). A idade média foi de 27,3 meses, as médias do comprimento axial e da ceratometria foram respectivamente 20,63 ± 2,11 mm e 44,94 ± 2,44 dioptrias. A ceratometria foi significativamente mais curvo e comprimento axial significantemente mais curto em crianças mais jovens (P<0,001). Não foram encontradas diferenças significativas na comparação entre os olhos com cataratas unilaterais e bilaterais e comparando os olhos com catarata unilateral a correspondentes olhos saudáveis (P>0,05). Conclusão: Os valores de ceratometria e comprimento axial mudam significativamente com a idade, principalmente nos primeiros seis meses de vida. Foi estabelecida uma relação funcional linear entre comprimento axial e ceratometria com o logaritmo da idade e entre ceratometria e comprimento axial.
