ABSTRACT This case report presents a patient who underwent photorefractive keratectomy 13 years after Acanthamoeba infection. The patient experienced prolonged difficulties in epithelialization during the postoperative period, leading to suspicion of reactivation. This case underscores the complexity and challenges in managing patients with a history of photorefractive keratectomy and ocular infections, particularly in cases involving Acanthamoeba. Understanding such cases is crucial for optimizing treatment strategies and achieving favorable outcomes.

ABSTRACT Objective: To evaluate theoretical knowledge of medical students, medical residents and general medicine specialists in fundus examination. Methods: This cross-sectional study included three groups: third year medical students, interne medicine residents and general medicine specialists. The selection was based on the expected proficiency for each of the groups. Participants were invited by email. Two questionnaires previously translated and validated to Portuguese were applied: one to evaluate self-confidence with fundus examination with a 5-item Likert scale and a second to […]

ABSTRACT Objective: To characterize the morphological aspects related to the integrity of the corneas. Methods: A biomicroscopic analysis of the corneas collected from January 2019 to January 2021, by the Human Eye Tissue Bank of Hospital João XXIII, in order to identify the main changes that led to their discarding, based on the medical records analyzed. Results: Almost all variables coincided with what the literature indicates; however, stromal infiltration manifested differently. Conclusion: The main discarding factors were epithelial exposure, epithelial […]

ABSTRACT Cavernous hemangiomas are benign malformations of vascular origin, generally well circumscribed and with slow growth. These lesions can be asymptomatic, being discovered unintentionally on imaging exams, or symptomatic, indicated mainly by the presence of proptosis, diplopia, and visual disturbances due to compression of the optic nerve. Preoperative evaluation is essential and makes the use of imaging exams essential for carrying out adequate planning, with computed tomography and magnetic resonance imaging being the first choices. Treatment can be conservative or […]

ABSTRACT Objective: To examine the relationship between hormonal changes, particularly estrogen, and lacrimal gland function in dry eye syndrome using a surgically induced menopausal rat model. Methods: Twenty-four female rats were divided into four groups: control, ovariectomized, ovariectomized with estrogen replacement, and ovariectomized with phytoestrogen replacement. Rats with regular estrous cycles were selected via vaginal cytology. Ovariectomy was performed on ovariectomized groups, and ovariectomized with estrogen replacement and ovariectomized with phytoestrogen replacement groups received hormonal interventions. Histological analysis assessed collagen […]

ABSTRACT Objective: To evaluate 1-year real-world results of effectiveness and safety of selective laser trabeculoplasty as an alternative to eye drops in patients with early to moderate open-angle glaucoma. Methods: This is a retrospective longitudinal study of a series of cases undergoing selective laser trabeculoplasty in patients with early to moderate open-angle glaucoma who were in use of topical anti-glaucoma therapy. The ability to reduce the intraocular pressure and the medication burden were evaluated, as well as the occurrence of […]

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 [...]
