Objective: to identify the visual acuity of school children using the Snellen Test and refer and carry […]

ABSTRACT Objective: To assess the accuracy of general practitioners in recognizing diabetic retinopathy through color retinal retinography, with a two-hour training course, by comparing the capacity of screening and classifying diabetic retinopathy. Methods: In the first arm of the study, of 142 diabetic patients included, 274 eyes were evaluated, and these patients were examined with an indirect binocular ophthalmoscope and classified according to the degree of diabetic retinopathy. In the second arm of the study, 14 physicians who are not […]

ABSTRACT Objective: To analyze the morphological and functional long-term outcomes of amniotic membrane transplantation after ocular surface chemical burns. Methods: This prospective study analyzed 7 patients who suffered from severe ocular surface burn and underwent amniotic membrane transplantation from 2015 to 2020 in Hospital de Clínicas – Universidade Federal do Paraná. Results: Out of the seven patients, six (85.7%) suffered unilateral burn and one (14.3%) suffered bilateral burn. Five of them had alkali burns (71.4%), one had acid burn (14.3%) […]

ABSTRACT Objective: To evaluate the effect of 0.2% brimonidine eye drops in reducing hyperemia and ocular bleeding during strabismus surgeries, in comparison with 0.025% naphazoline + 0.3% pheniramine eye drops. Methods: Fourteen patients with strabismus and indication for bilateral surgical correction were evaluated. Before the procedure, the eye drops were instilled randomly in each eye of the evaluated patients. The subjective analysis of conjunctival hyperemia and perioperative bleeding was performed in a double-blind manner, by 02 surgeons. The objective assessment […]

ABSTRACT Objective: To describe the clinical and epidemiological characteristics, surgical techniques, and results of the canalicular laceration treatment at our service. Methods: A retrospective study was carried out from January 2012 to June 2020, considering canalicular injuries operated at a reference center. Demographic data, lesion characteristics, surgical details, and treatment outcomes were obtained from electronic medical records and were statistically analyzed.

ABSTRACT Introduction: To obtain fundoscopy images through portable and low-cost equipment using artificial intelligence to assess the presence of DR. Methods: Fundus images of diabetic patients’ eyes were obtained by using a smartphone coupled to a device with a 20D lens. By using artificial intelligence (AI), the presence of DR was classified by a binary algorithm. Results: 97 ocular fundoscopy images were evaluated (45 normal and 52 with DR). Through AI diagnostic accuracy around was 70% to 100% in the […]

ABSTRACT Purpose To demonstrate the epidemiological profile and risk factors of patients with age-related macular degeneration (ARMD). Methods Observational and sectional study.

ABSTRACT Objective To describe and validate an ophthalmic model for corneal transplantation and micro suture training using a bovine eyeball as a model. Methods For the training model, the eyeball was placed under the sanitary field placed on the ends of a common 3.5cm diameter cylindrical plastic container for corneal removal. A superficial circular incision was made, then 9cm curved Castroviejo scissors were used for complete corneal removal. The cornea was replaced in its original position, and 10-0 nylon thread […]
