ABSTRACT Purpose: To describe a new accessible model of ophthalmological training using chicken eggs. Methods: With the aid of a spherical drill, the external calcified layer and the cuticle of the chicken eggshell were removed in a 2cm diameter circle. Using a video-magnification system, the film was dissected and cut to approximately 1.5 cm diameters. The film was removed and repositioned to make interrupted 12-0 nylon microsutures. The parameters analyzed were: cost, facility of acquisition and handling, time for making […]

ABSTRACT Objective: To outline the epidemiological profile of cornea donors and recipients before reaching queue zero. Methods: Epidemiological study, of quantitative approach, with transversal, analytical design, analyzing database records from the Health Secretary of the State of Ceará, from 2013 to 2015. Results: We obtained 1,558 cornea donors and 2,287 cornea recipients from 2013 to 2015. Most donors were male, capital residents, from 21 to 40 years old. Of donated eyeballs, 14.52% were disposed, due to poor condition, infiltration or […]

ABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. […]

ABSTRACT Objective: To measure visual acuity in high contrast and low contrast sensitivities in different grades of visible light transmission films in three different positions (front, lateral and rear windows). Methods: Forty-four healthy volunteers between 30-75 y-o, with BCVA better than 0,5, were tested in the 5 following vehicles with different grades of visible light transmission films. Vehicle 1: 75% in the front and 70% in the lateral and rear windows; Vehicle 2: 70% in the front and lateral windows […]

ABSTRACT Objective: To report, through a case series, the perception of patients about the effectiveness of corneal tattooing in the cosmetic improvement of their eyes with leukomas, using a combination of two techniques. Methods: Eight patients answered a survey regarding their cosmetic appearance satisfaction regarding the procedure, postoperative discomfort, and social impact observed after surgery. Results: All patients considered themselves very satisfied with the cosmetic results. Regarding the degree of postoperative discomfort, 75% said they had little discomfort, while 25% […]

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left […]

ABSTRACT Objective: Delineate an epidemiological profile of patients affected by eyelid tumors, while comparing the rate of correct clinical diagnosis to the gold standard histopathological analysis, verifying the data with the literature. Methods: Retrospective analysis of medical records, from 2015 to 2019, of patients submitted to excisional biopsy of the lesions with consequent histopathological classification of the anatomical specimen. Patients’ age and sex and tumors location, clinical diagnosis and histopathological classification were considered. Results: In total, 331 eyelid tumors from […]

ABSTRACT Objective: To describe results of pterygium surgery at Clínica de Cirurgía Ocular Villavicencio, in Meta, Colombia. Methods: A retrospective analysis of pterygium surgeries performed between January 2017 and December 2019. Results: Approximately 1,200 records were reviewed, and 1,200 procedures included. The most frequent complications were corneal Dellen, pterygium recurrence, graft retraction and pyogenic granuloma (7.5%, 2.5%, 3% and 0.75% respectively). These were identified within the first 6 months of surgery. Conclusion: Pterygium surgery using conjunctival autografts is an effective […]
