Objective: To determine the most cost-effective strategy for the treatment of early-stage primary open-angle glaucoma, by comparing the following alternatives: observation, medical therapy or laser treatment. Methods: Using a Markov model, from the perspective of the Brazilian Public Health System (SUS) and a horizon of the average life expectancy of the Brazilian population, we compared the incremental cost-utility ratio (ICUR) among the three treatment alternatives, as well as their costs and the gain in quality of life as measured in […]

Objective: Evaluate ocular trauma cases related to falling in elderly patients e compare the prevalence and severity of the cases. Methods: A series of cases was made with 52 patients aging 60 or more within the period of 36 months presenting ocular trauma related to falling, whereas the prevalence between the gender, the need for hospitalization or surgery and subsequent visual deficit were evaluated, as well as the severity of the cases. Results: Thirty-three (63.5%) of 52 patients were from […]

Objective: To compare the effectiveness of metamizole versus ibuprofen for the reduction of pain in retinal photocoagulation (RP). Method: A double-masked randomized controlled study was performed. Thirty-four patients with diabetic retinopathy were enrolled. The patients were randomized into two groups. Group A received oral 1000 mg metamizole. Group B received an oral intake of 600 mg ibuprofen. Pain during RP was assessed using a visual analog scale. Results: The mean pain scores for groups A and B were 5.2±2.6 and […]

The authors make a review of drusenoid retinal pigment epithelium detachments(DPDs), a form of retinal pigment epithelium detachment(PED) that evolves from confluent and large soft drusen.Drusenoidretinal pigment epithelial detachments are a recognized element of the “dry” AMD. Until now, no treatment is indicated in drusenoid PEDs. The authors describe the clinical characteristics of drusenoid retinal pigment epithelium detachments (DPEDs) and make a review of the DPEDs related in the international literature. We related in this revision paper the multimodal advanced […]

Objective: To determine the measurements of interpupillary distance (IPD) and ocular convergence in the presbyopic population with corneal reflex pupillometer. Methods: 160 subjects (66 males and 94 females) aged 41 to 85 years have their measurements of IPD done – far and near – by CRP method. Results: The mean age was 55.9 ± 11.5 years; the average IPD was 65.02 ± 2.78 and 62.47 ± 3.15 mm for male and female respectively. Also, the average convergence was 5.00 ± […]

Purpose: To evaluate the changes of corneal biomechanical after femtosecond laser – assisted cataract and to compare the parameters derived by Corvis ST between standard phacoemulsification and femtosecond laser – assisted in cataract surgery Methods: This is a prospective study. 151 eyes of 127 patients were under went cataract surgery. 75 eyes of 65 patients were with femtosecond laser–assisted (FS)(Alcon Len Sx, Aliso Viejo,USA) and 76 eyes of 62 patients with standard phacoemulsification (SP) (Alcon Infinit, Fort Worth, USA). Lens […]

Objective: To evaluate the introduction of the femtosecond laser (FSL) to perform the key steps of the traditional cataract surgery process and the operational difficulties and safety of this new technology during routine use in an operating room in Brazil. Methods A retrospective study was conducted using the first cases operated on at a single center using the laser platform LenSx/Alcon with a soft contact lens patient interface.All patients underwent a detailed preoperative assessment.The anterior capsulotomy, nuclear fragmentation, and corneal […]

Objective: To analyze the incidence and characteristics of accidents with biological material in an ophthalmology hospital in the Northeast of Brazil. Methods: Retrospective descriptive study on ducted through a survey of biological material accidents notified by Comunicação de Acidentes de Trabalho (CAT) during 2010-2013. Results: 34 accidents were reported, 26 (76.5%) workers were females and 8 (23.5%) were males. The mean age was 30.0 ± 5.9 years. Forty-eight (82.3%) accidents occurred in the surgical room of the hospital, 15 (44.1%) […]
