ABSTRACT The accuracy of the intraocular lens calculation is not perfect, and postoperative refractive errors are common, especially in patients who have undergone previous refractive surgery or in presence of asymmetric corneas. Corneal power after refractive surgery can be more accurately measured using the total optical power map in the 4-mm central zone, by means of Orbscan II or equivalent keratometric reading map available on pentacam, with central measurements of 1.0, 2.0, 3.0 and 4.5 mm. The purpose of this […]

Glaucoma is the leading cause of irreversible blindness in the world, affecting approximately 60 million people;(1) and the estimates for 2040 are over 110 million individuals.(2) The surgical treatment scenario of glaucoma has undergone major changes in recent decades with the introduction of selective laser trabeculoplasty (SLT), less aggressive cyclodestructive procedures and minimally invasive glaucoma surgery (MIGS). […]

ABSTRACT Objective To evaluate efficacy of gonioscopy-assisted transluminal trabeculotomy and relate to severity of glaucoma. Methods A retrospective analysis of medical records of patients submitted to gonioscopy-assisted transluminal trabeculotomy, at a private hospital, from 2019 to 2021. Results A total of 20 were submitted to gonioscopy-assisted transluminal trabeculotomy (2 eyes) or facectomy and gonioscopy-assisted transluminal trabeculotomy (18 eyes). Patients with advanced-stage disease achieved a decrease by 5 mmHg (26.5%) in IOP, with a reduction of 2.3 drugs, and eyes with […]

Dear Editors: We read with interest the paper entitled “Space travel: A challenge from the point of view of ophthalmology” by Cunha et al.,() recently published at Revista Brasileira de Oftalmologia. The authors stressed that currently, with the emergence of new technologies promoting novel and even more ambitious space programs, aerospace medicine has increasingly gained prominence in the scientific community. Hence, there is an urgent need for specific studies exploring changes in human physiology during space missions, with the aim […]

Abstract Ocular toxoplasmosis can present with an atypical, rare, bilateral involvement, and associated with acute retinal necrosis. It occurs in immunosuppressed patients, resulting in severe visual loss, if not quickly solved. We report an atypical case of ocular toxoplasmosis in a diabetic patient, who already showed a systemic aspect in a previous hospitalization, which was elucidated by the ophthalmologic examination and history. In addition, the routine of the uveitis sector requesting serology in a directed and careful way was essential […]

ABSTRACT Objective To compare efficacy, durability and postoperative complications of frontal suspension with the use of autologous fascia lata, silicone sling or polypropylene suture. Methods A descriptive, analytical, observational and retrospective study of patients with severe ptosis who underwent frontalis suspension, during a 2-year period. Data analyzed included comparative margin to reflex distance, palpebral fissure, and complications. Results Fascia lata was the material that provided the best results of margin to reflex distance and palpebral fissure in the postoperative analysis […]

ABSTRACT Objective To screen pregnant women with positive serological results for toxoplasmosis using non-invasive, ultra-wide field retinal imaging. Methods Prospective, descriptive longitudinal study including pregnant women with positive serological results for toxoplasmosis seen at three maternal care reference units located in Belém (PA), in the Brazilian Amazon. Patient data were collected via interview. Comprehensive eye examination, including best corrected visual acuity, biomicroscopy, tonometry and ultra-wide field imaging, was performed every three months. Results The sample comprised 36 pregnant women. Of […]

ABSTRACT Objective: To retrospectively evaluate the influence of intracorneal ring thickness on reduction of corneal astigmatism in patients with keratoconus. Methods: From a database of 2,033 eyes submitted to corneal ring implant surgery, a sample of 90 eyes with similar keratometry and astigmatism characteristics was selected. All eyes in this study received two segments of traditional arc length of approximately 160°, with varying thicknesses: Group A received two segments of 150 µm; Group B received two segments of 200 µm, […]
