Both types of punctal plugs led to an improvement of the fluorescein and rose bengal staining scores in eyes with KCS. The difference in the retention rate and complications between the two types of plugs was probably caused by the differences in the material and the design of the plugs. Close monitoring is necessary to check for loss of plugs and to prevent complications.

RESUMO: Introdução: O câncer de boca e o câncer de orofaringe são doenças influenciadas por fatores socioeconômicos. O risco de desenvolver essas doenças aumenta com a idade, e a maioria dos casos ocorre em idosos, com elevadas taxas de mortalidade. O objetivo deste estudo foi analisar a influência dos índices socioeconômicos municipais nas taxas de mortalidade por câncer de boca (CB) e de orofaringe (CO) em idosos nas 645 cidades do estado de São Paulo, Brasil, nos anos de 2013 a 2015. Método: Dados secundários de óbitos foram obtidos pelo Sistema de Informações sobre Mortalidade (SIM) do Ministério da Saúde. O número de idosos e os valores da renda média per capita e do índice de desenvolvimento humano por município (IDH-M) foram obtidos a partir dos dados da Fundação SEADE. Realizou-se a análise descritiva e exploratória dos dados, seguida de modelos binomiais negativos descritos pelo procedimento PROC GENMOD e avaliados pelo critério de informação de Akaike corrigido (AICc), pelo grau de liberdade e pelo teste de Wald (α=0,05). Resultados: Cerca de 30% das cidades notificaram óbitos em 2013, 16,74% em 2014 e 18,61% em 2015. Astaxas médias de mortalidade por CB e CO foram, respectivamente, de 20,0 (± 30,9) e 10,7 (± 17,5) por 100milhabitantes. A renda média variou de R$ 434,20 a R$ 2.009,00 e o IDH-M, de 0,65 a 0,89. Houve decréscimo significativo (p < 0,05) nas taxas de mortalidade por CB e CO em idosos com o aumento dos valores das rendas médias e do IDH-M. Conclusão: As desigualdades socioeconômicas das cidades influenciam nas taxas de mortalidade por CB e CO em idosos.

Sunglasses not only protect against glare but also stabilize visual quality under various light conditions (e.g. passing through a tunnel while driving). Aging changes in lens transparency should be specially considered when developing protective eyewear.

Purpose: To predict the postoperative anterior chamber (AC) depth from the preoperative in situ position of the lens central clear zone (CCZ) using Scheimpflug slit photography. Methods: 111 eyes of 78 cases that underwent phacoemulsification and intraocular lens (IOL) implantation were examined. 748 eyes of 383 healthy subjects with transparent lenses were used as the control. Scheimpflug slit photography was done under maximal mydriasis, and biometry was performed on the photographs. Two types of acrylic IOLs (MA30BA and MA60BM, both from Alcon) were used in this study. The preoperative AC depth (L1), the distance between the anterior lens capsule and lens CCZ (L2) and the postoperative AC depth (I1) were determined. I2, the predicted postoperative AC depth, was then determined from a linear regression of L1 + L2 and I1. Results: L2 thickened by 0.014 mm/year, and L1 decreased by 0.016 mm/year in the transparent lenses. L1 + L2 changed little with aging in both cataractous and transparent lenses. L1 + L2 and I1 showed a linear correlation with r = 0.80 in the MA30BA and r = 0.77 in the MA60BM groups. The mean error values between I1 and I2 were 0.095 ± 0.096 and 0.123 ± 0.114 mm in MA30BA and MA60BM, respectively. The error between I1 and I2 was within ± 0.17 and ± 0.33 mm or less in 72.9 and 91.5% of MA30BA and in 82.7 and 96.2% of MA60BM. In contrast, the error between I2 and I1 when calculated using the SRK/T formula was much larger – in excess of ± 0.33 mm in 38.7% of the eyes. Conclusions: L1 + L2 changes little with aging and is considered a useful marker of the position of the crystalline lens in situ. There was a high correlation between I1 and L1 + L2. These allow a far more accurate prediction of I1 than previous methods. In combination with the conventional regression formula and ray tracing, a highly accurate IOL power calculation can be attained.

A 17-year-old woman with arterial and venous thrombosis of the leg diagnosed as antiphospholipid syndrome (APS) associated with systemic lupus erythematosus (SLE) is reported. Her serum C-reactive protein (CRP) was elevated and complement concentrations were normal. Symptoros of APS were improved with prednisolone, when the serum CRP concentration decreased, and low serum complement concentration and white blood cell count appeared. These are characteristic features of SLE. h is suggested that APS is a possible complication of SLE and may modify the clinical features of SLE.

A 23 year-old-man, who had no problem in visual acuity , eye-position, eye-movement or near stereopsis but had poor depth perception and no stereopsis on major amblyoscope , was given orthoptic training to try to improve binocular function. The training consisted of fusional convergence by prism and stereopsis training by using the stereoscope.
