Objective: To describe and analyze the prevalence of visual impairment and its causes in public school students in Belo Horizonte/MG. Methods: Cross-sectional study of 1.452 public school children from 5 to 19 years old, in Belo Horizonte/MG, screened and evaluated between 2011 and 2014. Results: Of the total sample, 150 patients (10,33%) had low visual acuity at the screening, and were referred to an ophthalmologist to further examination. Forty (26%) of the referred patients presented at the ambulatory, where 29 […]

Purpose: To describe the impact of aged-related macular degeneration (AMD) on vision-related quality of life (QOL) on a sample of portuguese patients and explore the association with vision, Central Foveal Thickness (CFT) and demographic variables in a Portuguese population. Methods: Observational, interview study of 68 patients with clinical diagnosis of NV AMD seen between January and April 2011 at the Ophthalmology Department of Centro Hospitalar de Lisboa Ocidental. Health-related quality of life (HRQL) was measured with a Portuguese version of […]

Objective Compare visual acuity (VA) of patients after cataract surgery with and without intraoperative complications regarding possible factors that contributed to the outcome on postoperative follow-up. Methods Longitudinal, retrospective study that evaluated 179 medical records of patients who underwent cataract surgery under the technique Phacoemulsification (PHACO) in the Suel Abujamra Institute from february to july 2013. Patients were divided into two groups concerning presence or absence of intraoperative complications. Data were analyzed using t-test methods for two samples or (ANOVA) […]

Purpose: To evaluate the visual function of patients with bilateral implantation of multifocal diffractive IOL AT Lisa 809MTM by visual acuity with and without correction, contrast sensitivity curve, defocus curve and visual function questionnaire (39 VQF). Methods: Interventional clinical prospective study, which evaluated the results of 20 eyes of 10 patients who underwent phacoemulsification and IOL implantation between february and june 2012. Results: The average of residual postoperative ametropia was 0.05 ± 0.42 (-0.75 to +1.25 D) spherical diopters and […]

Objective: To establish the influence of assistive technology devices (ATDs) on the performance of activities by visually impaired schoolchildren in the resource room. Methods: A qualitative study that comprised observation and an educational intervention in the resource room. The study population comprised six visually impaired schoolchildren aged 12 to 14 years old. The participants were subjected to an eye examination, prescribed ATDs comprising optical and non-optical devices, and provided an orientation on the use of computers. The participants were assessed […]

OBJECTIVE: Evaluation of patients undergoing sequential sessions of RV and report its benefit in improving visual acuity (VA). METHODS: Cross sectional study with a sample of 10 patients who underwent sequential sessions of the RV. Patients were treated at a rate of 2-3 sessions per week for a period of 2 to 3 months and was completed after 20 to 40 sessions. The main inclusion criteria were post cataract surgery (without complications) and multifocal IOL until +3.00 D, astigmatism <-1.00 […]

PURPOSE: Development and validation of quality of life questionnaire in pseudophakic patients in Portuguese. METHODS: The modified Cataract TyPESpecification questionnaire was specifically developed to assess quality of life after cataract surgery, functional status evaluated with 10 items and contains 18 questions. All questions were applied by a single examiner, with the goal of graduating visual satisfaction from 0 to 10 (0 means very dissatisfied, 5 neutral, 10 very satisfied).This prospective comparative study included 142 eyes of 71 patients in Sao […]

To correct a high hyperopia and irregular astigmatism secondary to multiples refractive surgeries in a 45 years old female, radial incisions suture and intraocular (IOL) Acrysof Toric lens was performed. To correct the residual refractional error a pseudophakic toric supplementary IOL was implanted over the primary one.The initial visual acuity (VA) was LogMAR 0,9 and the final VA was LogMAR 0,3. The implant of IOL supplementary over a primary toric IOL appears to be a good option, increasing the visual […]
