ABSTRACT Objective: To assess the knowledge of healthcare professionals about corneal biomechanics in glaucoma and identify knowledge gaps for educational focus. Methods: A cross-sectional observational study involving an online questionnaire addressing knowledge and the importance of corneal biomechanics in glaucoma patients, completed by volunteer ophthalmologists, glaucoma specialists, and physicians from other specialties residing in Brazil. Data analysis was based on knowledge about the subject in these three groups, and the analyses were performed using the Statistical Package for Social Sciences, […]

ABSTRACT The aim of this case report was to evaluate the outcome and methodology of a novel technique for conjunctival pigmentation using modified micropuncture to enhance the appearance of an ocular graft from an eviscerated eye. This approach used modified micropuncture for conjunctival pigmentation and sclera in an ocular graft. Due to the lack of a cornea, multiple sessions were required to ensure proper pigment penetration. The procedure’s effectiveness was evaluated based on aesthetic results and patient satisfaction. The technique […]

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 […]
