ABSTRACT
Objective: Evaluate the anatomical, refractive, and functional results of an innovative technique of deep anterior lamellar keratoplasty with a manual spatula. Materials and Methods: We evaluated the results and examinations of 16 eyes from 14 patients who underwent deep anterior lamellar keratoplasty using the technique described by Ferrara. Residual bed thickness after keratoplasty was evaluated postoperatively using Visante. The measurement was performed using a technique similar to that used to measure fl ap thickness after laser in situ keratomileusis refractive surgery. The measurements were performed at the center of the cornea in an area comprising the central 3-mm in the 45° and 135° meridians. Results: Best-corrected visual acuity was 0.34 ± 0.18 LogMar (0.09 to 0.60 LogMar), the spherical equivalent was -4.31 ± 3.38 D (+0.25 to -9.50 diopters), and keratometry was 45.75 ± 2.77 D (41.11 to 52.48 diopters) postoperatively. Corneal astigmatism was 3.19 ± 2.78 D (0.18 to 11.81 diopters). Residual stromal bed thickness measured by optical coherence tomography showed values of 67.1 ± 24.3 μm (30 to 109 μm). The statistical correlation by Spearman’s test between the best-corrected visual acuity and the residual stromal bed thickness was 0.11 (P = 0.67). Conclusion: Deep anterior lamellar keratoplasty, in which manual dissection was performed using an instrument similar to that used to implant corneal rings, provided good visual and anatomical results.
ABSTRACT
Objetivos: Verificar a relação entre a idade ao diagnóstico de DM tipo 2 e a necessidade de uso insulina. Determinar os possíveis papéis do sexo, peso, pressão arterial, lipídios sangüíneos, relação cintura-quadril e circunferência abdominal no uso precoce de insulina em pacientes com DM tipo 2. Métodos: Medimos as variáveis do estudo nos pacientes que compareceram à Clínica de Diabetes do Ambulatório Central da Universidade de Caxias do Sul e naqueles que se apresentaram em duas Ações Comunitárias (forças-tarefas realizadas pela Universidade, cujo objetivo é de oferecer serviços de diferentes profissionais à comunidade) entre setembro de 2002 e agosto de 2003. Resultados: A amostra foi composta de 61,1% de mulheres e 38,9% de homens. Do total, 17,7 % usavam insulina. O tempo decorrido do diagnóstico de diabetes foi maior entre os usuários do que nos não-usuários de insulina (9,6 ± 9,2 vs 6,0 ± 6,1 anos; p=0,043). A média de idade ao diagnóstico foi similar entre usuários e não-usuários de insulina (52 ± 16,1 ± 11,4 vs 50 ±11,4 anos; p = 0,8) Conclusão: Não houve diferença estatisticamente significativa entre a idade ao diagnóstico de DM tipo 2 e o uso de insulina (AU)
Aim: To verify the relationship between age at diagnosis of Type 2 Diabetes and the need of insulin requirement. To determine the possible role of gender, blood pressure, blood lipids, waist to hip ratio, and abdominal circumference on the early onset of insulin use in patients with type 2 diabetes. Methods: We measured the study variables in patients who did attend to the Diabetic Clinic at the Central Ambulatory of the University of Caxias do Sul and in those presented in two Cumunitarian Actions (task-forces carried out by the University which the aim is to offer the services of different professionals to the community) between September 2002 and August 2003. Results: The sample was composed by 61,1% of women and 38,9% of men. From the total sample, 17,7 % of the patients where on insulin use. The time elapsed from the diagnosis of diabetes was greater in the users than in non-users of insulin (9,6 ± 9,2 vs 6,0 ± 6,1 years; p =0,043). The mean age at diagnosis was similar between users and non users of insulin (52 ± 16,1 ± 11,4 vs 50 ± 11,4 years; p = 0,8). Conclusion: There was not statistically significant difference between the age of diagnosis of type 2 diabetes and the use of insulin (AU)
