Visual performance of scleral lenses and their impact on quality of life in patients with irregular corneas
Conclusion: Scleral contact lenses are an effective alternative visual correction method for keratoconus, pellucid marginal degeneration, and post-keratoplasty astigmatism. A significant increase in visual acuity and contrast sensitivity can be obtained with scleral contact lenses in patients with irregular corneas.RESUMO Objetivo: Avaliar o desempenho da qualidade visual das lentes de contato esclerais em pacientes com ceratocone, degenera ção marginal transparente e astigmatismo pós-ceratoplastia e seu impacto na qualidade de vida. Métodos: Foram incluídos 40 pacientes (58 olhos) com ceratocone, degeneração marg...

Effect of superior blepharoplasty on tear film: objective evaluation with the Keratograph 5M - a pilot study
Conclusions: The results of this pilot study suggest that upper blepharoplasty does not affect tear breakup time according to the objective evaluation of breakup time with the Keratograph 5M.RESUMO Objetivos: Avaliar o efeito da blefaroplastia superior no filme lacrimal, utilizando o top ógrafo de córnea Keratograph 5M. Métodos: Foi realizado estudo prospectivo de 27 olhos de 14 pacientes com dermatocálase superior submetidos à blefaroplastia superior entre maio e junho de 2016. A blefaroplastia palpebral superior conservadora foi realizada por ressecção em bloco de tecido l amelar anterior que incluiu pele, tecid...

Effects of combined oral doxycycline and topical cyclosporine treatment on ocular signs, symptoms, and tear film parameters in rosacea patients
Conclusions: Our results support the finding that topical cyclosporine in addition to the standard regimen improves tear function, as shown by Schirmer test and break-up time scores, in ocular rosacea patients.RESUMO Objetivo: Este estudo relata os efeitos do uso combinado de doxiciclina oral e ciclosporina t ópica sobre sinais e sintomas oculares e sobre parâmetros do filme lacrimal em pacientes com rosácea. Métodos: Cinquenta e quatro olhos direitos de 54 pacientes foram incluídos no estudo. Todos os pacientes foram submetidos a exame oftalmológico completo - incluindo a melhor medida da acuidad e visual corrigid...

Evaluation of choroidal perfusion changes in obese patients: ocular effects of insulin resistance
Conclusion: We found reduced mean choroidal thickness and ocular pulse amplitude and increased mean intraocular pressure in obese patients. These changes indicated a decrease in choroidal perfusion and ocul ar blood flow. It may be possible to detect ocular blood flow changes in obese patients through noninvasive assessment using the choroid. The negative correlation between insulin resistance and ocular pulse amplitude may be associated with intracellular fat accumulation in obese patients.RESUMO Objetivo: Avaliar as altera ções da perfusão coroidiana em pacientes obesos utilizando tomografia de coerência óptica e a...
