ABSTRACT
A necrobiose lipoídica (NL) é uma dermatose granulomatosa, que acomete principalmente diabéticos devido à degeneração do colágeno. Embora existam diferentes tratamentos, todos apresentam pouca resposta. Dentre as opções, a luz intensa pulsada (LIP) e o laser Erbium-YAG permitem aumentar a produção e remodelamento do colágeno tratando a atrofia, além de diminuir o eritema pela coagulação de vasos sanguíneos. Relata-se caso de mulher, 24 anos, com diabetes mellitus tipo I, submetida a tratamento de NL no antebraço esquerdo em sete sessões com a associação entre LIP e laser Erbium-YAG 2940nm. Observou-se melhora da atrofia central e do eritema.
Necrobiosis Lipoidica (NL) is a granulomatous dermatosis, mainly affecting people with diabetes due to collagen degeneration. Although there are different treatments, all have little response. Among the options, the Intense Pulsed Light (IPL) and the Laser Erbium-YAG enhance the production and remodeling of the collagen treating the atrophy, besides reducing the erythema by the coagulation of blood vessels. We report a case of a 24-year-old woman with type I Diabetes Mellitus who underwent NL treatment on her left forearm in seven sessions with the association of IPL and 2940 nm Erbium-YAG laser. We observed improvement in central atrophy and erythema
ABSTRACT
PURPOSE: To analyze patient satisfaction and difficulties with bilateral multifocal intraocular lenses (IOLs) implantation and aspheric monofocal IOLs implantation using monovision, after cataract surgery. MATERIALS AND METHODS: A total of 61 participants were included in the study, 29 with monovision and 32 with multifocal lenses. The inclusion criteria were patients undergoing phacoemulsification for bilateral visual impairment due to cataracts and presenting with postoperative visual acuity of 20/30 or better for distance and line J3 or better for near vision. RESULTS: The 2 groups had similar results regarding difficulties with daily activities such as distance vision, near vision, watching television, reading, cooking, using a computer or cellphone, shaving/putting on makeup and shopping. There were differences in responses between the groups regarding difficulty with night vision (P=0.0565) and night driving (P=0.0291). Degree of satisfaction in terms of distance vision without glasses was statistically significantly better in monovision group (P=0.0332), but not for near (P=0.9101). CONCLUSION: Both techniques yielded satisfactory results regarding visual acuity for different activities without the need to use glasses. Multifocal lenses are a good option for patients with the exception of night driving, and who desire independence from glasses.
ABSTRACT
BACKGROUND: Keratoconus may progress to acute corneal hydrops even after cross-linking. In some cases, keratoconus progresses during pregnancy. In this report, we present a case of a patient with increased anterior stromal resistance after cross-linking that would favor nonprogression of keratoconus during pregnancy. CASE PRESENTATION: We report that cross-linking is likely to have had a protective effect in a white pregnant patient with acute corneal hydrops who showed rapid improvement, as documented by corneal topography. Improvement occurred within 8 days, whereas up to 250 days are reported in the literature. No keratoconus progression occurred in the 20-month follow-up period. CONCLUSIONS: Cross-linking failed to prevent the occurrence of acute corneal hydrops after rupture of Descemet's membrane but most likely helped to accelerate the resolution of the condition. Corneal hardening resulting from cross-linking may have also contributed to stabilizing keratoconus during pregnancy.
