ABSTRACT Objective: To evaluate refractive and topographic outcomes before and at least 7 years after intrastromal ring segment implantation surgery in patients with keratoconus. Methods: Long-term retrospective longitudinal study carried out with 35 patients (62 eyes) aged 10 to 30 who underwent intrastromal ring segment implantation using a manual technique. Different arc rings were analyzed across various keratoconus types. Results: Significant improvements in topographic astigmatism (p = 0.001) and corrected distance visual acuity (p < 0.001) were observed, with no [...]

ABSTRACT This review discusses various surgical techniques for correcting aphakia in patients without adequate capsular support, focusing on lens implantation methods and their associated outcomes. It evaluates anterior chamber intraocular lenses, iris fixation with or without sutures, and scleral fixation techniques, both sutured and sutureless. Each method is assessed for its visual acuity results, complication rates, and long-term stability. The advantages and disadvantages of iris and scleral fixation are compared, addressing risks such as endothelial loss, intraocular lens dislocation, and […]

ABSTRACT To report a case of Terson syndrome following a traumatic brain injury during a footvolley match. The patient was undergoing evaluation with the following tests: visual acuity, retinography, angiography, and optical coherence tomography. Follow-up was maintained for 3 months with conservative treatment. Terson syndrome associated with head trauma is poorly documented as fundoscopy is not performed in most patients.

ABSTRACT Objective To assess the best illumination for low vision patients of a vision rehabilitation center. Methods A cross-sectional observational study was conducted with patients aged 10 years and older, visual acuity < 20/60 and ≥ 20/200 on the best eye. Four types of lamps of power equivalent to 60 W (halogen, warm LED, daylight LED and white LED). All of them were used in standardized fixtures, and the analysis was performed during the reading activity. The first step included [...]

ABSTRACT Objective: To identify, care for and report on the experience of combating visual disorders of schoolchildren in the countryside of Bahia. Methods: Experience report on visual triage, using the Snellen table, conducted in public schools with students from the 2nd to the 4th grade of elementary school in the city of Feira de Santana (Bahia). Referral criteria for ophthalmological consultation were Detection of visual acuity equal to or less than 20/30 in one eye; presence of complaints or external […]

ABSTRACT Choroidal tuberculoma is a rare form of ocular tuberculosis that poses a diagnostic dilemma when there is no systemic manifestation. We describe a case of a 37-year-old lady who presented with decreased vision and superior visual field defect in her right eye for a duration of 2 weeks. The right eye visual field defect was described as a superior altitudinal field defect. Her visual acuity in the right eye was 20/30. Right fundus examination revealed an elevated hypopigmented subretinal […]

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 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, […]
