Objective: To evaluate the variation of intraocular pressure and ocular perfusion pressure during hemodialysis sessions, in the pre, intra (hourly) and post dialytic periods, in patients treated at Hemodialysis Reference Services in Fortaleza – CE. Methods: The study was longitudinal and prospective. 45 patients underwent hemodialysis. All patients were recruited to undergo an ophthalmologic examination, in addition to the intraocular pressure measurement with Tonopen. Results: The sample consisted of 26 men and 19 women with a mean age of 51.8 […]

Objective: To compare macular and peripapillary retinal nerve fiber layer thicknesses of dominant eye and non-dominant eye using optical coherence tomography (OCT). Methods: 104 eyes of 52 healthy young adults were included. Ophthalmological examinations; including measuring refraction, best corrected visual acuity, intraocular pressure (IOP) measurement, slit-lamb biomicroscopy, dilated fundus examination, measuring of central macular thickness (CMT), and peripapillary retinal nerve fiber layer (PRNFL) thickness were performed on each subject. Hole-in-the-card test was used to detect the ocular dominance. Results: There […]

Objetivo: Comparar as espessuras da camada de fibras nervosas da retina macular e peripapilar do olho dominante e não dominante usando a tomografia de coerência óptica (OCT). Métodos: 104 olhos de 52 adultos jovens saudáveis foram incluídos. Exames oftalmológicos; incluindo medidas de refração, melhor acuidade visual corrigida, medição da pressão intraocular (PIO), biomicroscopia de fenda-cordeiro, exame do fundo dilatado, medição da espessura macular central (CMT) e espessura da camada de fibras nervosas da retina peripapilar (PRNFL) foram realizadas em cada […]

Objetives: To assess the degree of fungal and bacterial contamination of hypotensive eye drops and the way these are preserved by the patients at the Glaucoma outpatient clinic of Santa Casa Hospital in Ribeirão Preto. Methods: Fifty-five patients were randomly assigned to follow-up in the outpatient clinic and, after their consent, an eye drop was collected per patient and later sent by mail for analysis by microbiologist and pathologist in up to 72 hours. Approximately 0.5ml of the medications were […]

Objetive: To evaluate the association between sympathetic nervous system activity and blood pressure variability with central serous chorioretinopathy (CSC). Methods: We performed an individual, observational, and cross-sectional study involving 11 patients with CSC and 16 healthy individuals in similar age range. Participants underwent spectral power analysis of heart rate variability (HRV) at the Hypertension Department of Heart Institute at the University of São Paulo. Results: We demonstrated sympathetic activity predominance in CSC group and found that the LF (low frequency) […]

Objetivo: Avaliar a associação entre a atividade do sistema nervoso simpático e a variabilidade da pressão arterial com a coriorretinopatia serosa central (CSC). Métodos: Estudo individuado, observacional e transversal envolvendo 11 pacientes com CSC e 16 indivíduos saudáveis de idade semelhante. Os participantes foram submetidos à análise de poder espectral da variabilidade da freqüência cardíaca no Departamento de Hipertensão do Instituto do Coração da Universidade de São Paulo. Resultados: Observamos o predomínio da atividade simpática no grupo com CSC, evidenciado […]

Objective: To analyze the quality of life among people with glaucoma according to the visual field defect. Methods: This is a cross-sectional, analytical study carried out in an ophthalmology unit, Glaucoma Project, in Montes Claros, Minas Gerais, Brazil. Patients’ quality of life was assessed using the National Eye Institute 25-Item Visual Function Questionnaire (NEI-VFQ-25). The Mean Deviation (MD) parameter of the best eye was used to classify the visual field defects in mild, moderate and severe. Results: Four-hundred patients participated, […]

Objective: To analyze the prevalence of asthenic symptoms in students of higher education and to assess their influence on academic performance and learning. Methods: Descriptive research with cross-sectional design through the application of the College of Optometrists Questionnaire in Vision Development Quality of Life (COVDL-QoL), in its cross-cultural and linguistic adaptation to the Portuguese language, to the students of a private college in the city of Montes Claros. Results: The questionnaire was answered by 132 university students. There was no […]
