ABSTRACT Objective: To validate visual acuity measurements using a cross-platform system in an ophthalmological setting. Methods: Visual acuity was assessed at a distance of 5m using two different modalities: printed and digital optotypes. The devices included Android, LG WebOS and Samsung Tizen smart TVs. Optotypes were presented in the logMAR scale. Two modalities, a single row and a block of symbols, presented Sloan letters and Tumbling E symbols. Results: Visual acuity measurements of 190 participants aged 12 to 60 years […]

ABSTRACT Objective: To present a novel, low-cost, and accessible methodology for capturing high-quality stereoscopic images and streaming it in real time to a standard three-dimensional television in a surgical setting, utilizing readily available smartphones. Methods: Two smartphones were attached to each eyepiece of the surgical microscope using a custom-made adapter. The smartphones recorded the surgical procedure and streamed the video via HDMI cables to a dual-input multi-viewer, which combined the feeds into a single image displayed on a conventional 3D […]

ABSTRACT Objective: This systematic review aimed to investigate the prevalence and incidence of optic neuropathy in older adults. Methods: A search was conducted in the following databases: Medline/Pubmed, Embase, Scielo, and BVS, and data extraction for this review encompassed the period up until March 2023, using MeSH terms and Boolean operators. The selected search strategy and methods were registered in the PROSPERO database (#CRD42023403901). Results: Twelve articles were included for analysis, comprising four case-control studies and seven cohort studies. The […]

ABSTRACT Objective: To know the profile of trabeculectomy, in addition to the success rate in controlling intraocular pressure in patients with glaucoma. Methods: A retrospective, observational study, with medical records of patients with glaucoma, followed up at an ophthalmological reference center, who underwent trabeculectomy from January 1, 2016 to May 31, 2017, by a single experienced surgeon. The success rate was considered with an intraocular pressure < 21 mmHg, for high intraocular pressure glaucoma, and a reduction of at least [...]

ABSTRACT Congenital distichiasis is a rare condition, of controversial origin, with therapeutic options not always having favorable results. This is a case report of a seven-year-old male child with congenital distichiasis affecting all eyelids, with the presence of some distichiasis hair follicles despite surgical treatment using the interlamellar division technique, selective application of cryotherapy and electrolysis. The treatment of congenital distichiasis involves the need to combine techniques to achieve more effective results.

ABSTRACT Purpose: To evaluate the visual, topographic, and refractive outcomes of the implantation of asymmetric segments (AS) of the ICRS intracorneal ring in eyes with keratoconus and irregular/asymmetric astigmatism (phenotypes type 2 Duck and 3 Snowman by morphological classification of Fernandez-Vega/Alfonso Keratoconus). Methods: Prospective clinical study including 60 patients (60 eyes) with keratoconus who underwent implantation of the Kearing ICRS selected and implanted according to the Mediphacos nomogram () with femtosecond laser. Preoperative and postoperative evaluations included uncorrected visual acuity, […]

ABSTRACT Objective: To outline the epidemiological profile of a reference ophthalmological emergency department, with no appointment scheduled, at a tertiary hospital in Southern Brazil. Methods: A cross-sectional historical study was conducted at Hospital Regional de São José, Santa Catarina, covering all visits to the ophthalmological emergency department over 46 days in 2019 (n = 1,728). Data were entered in a spreadsheet and analyzed using Statistical Package for Social Sciences, version 21.0.0.0), with frequencies and chi-square tests for categorical data (p […]

ABSTRACT Purpose: To compare data extracted from the Pentacam exam in patients with keratoconus in one eye and form fruste keratoconus in the other eye. Setting: Private clinic in São Paulo, Brazil. Design: Retrospective review. Methods: This study reviewed charts of patients with keratoconus in one eye and forme fruste keratoconus (FFKC) in the other, from January to December 2019. All subjects were evaluated with a rotating Scheimpflug imaging system. Twenty-two eyes of 11 patients were compared, and only one […]
