ABSTRACT Congenital stationary night blindness encompasses a heterogeneous group of inherited retinal dystrophies characterized by impaired scotopic vision from birth. This article provides a comprehensive overview of congenital stationary night blindness, focusing on its genetic underpinnings, clinical manifestations, and diagnostic approaches, with a specific emphasis on variants in the CACNA1F gene. Through a detailed case report of a 49-year-old male with congenital stationary night blindness attributed to a hemizygous variant in CACNA1F, we illustrate typical clinical presentations and correlate them […]

Dear Editor, In February 2023, the Revista Brasileira de Oftalmologia published a case of congenital bilateral dacryocystocele, by Pierre-Filho et al.() and I would like to congratulate the authors for raising this important topic. The article describes a child who presented with bilateral bluish enlargement of the lacrimal sacs from birth, along with tearing, which typically begins between the first and second week of age.(,) […]

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 […]
