O ensino oftalmológico na graduação médica é um momento muito importante na formação do aluno. É o primeiro contato formal no aprendizado da especialidade e, talvez, o único para a maioria que não vai seguir a carreira de oftalmologia. Nesse momento, ele aprende sobre a importância da visão, o quanto ela impacta na qualidade de vida das pessoas, as patologias oculares e como tratá-las, mas principalmente sobre sua correlação com inúmeras doenças sistêmicas. Nas palavras do Emérito Professor Newton Kara […]

A population-based cross-sectional survey based on a questionnaire developed using the Google Forms interface was carried out. The questionnaire was answered anonymously in order to ensure the confidentiality of data and […]

ABSTRACT Juvenile xanthogranuloma is a rare benign non-Langerhans cell histiocytosis. Clinical manifestation usually occurs up to the age of 2 years, with yellowish papules and variable clinical progression. Approximately 0.75% of patients had systemic involvement and 0.25%, ocular alterations. The purpose of this report is to describe a case of a preschool 2-year-old female patient, with nodules in the upper right eyelid, 0.5-cm wide, with well-defined edges, an uncertain date of onset, a stable growth for 6 months, with no […]

ABSTRACT We report 13 cases of large angle sensory strabismus treated with autologous graft of extraocular muscle. Recession-resection procedure of the horizontal rectus muscles was performed, and the flap from the resected muscle was sutured to the weakened muscle as an autologous expander. Six cases of exotropia and seven of esotropia, with mean prism diopter deviation of 75 (range of 70-90). There was significant improvement in the postoperative deviation, and mean prism diopter of 10.07 (range of no deviation to […]

ABSTRACT Traumatic chiasmal syndrome is one of the rare etiologies of chiasmal syndrome, characterized by optic chiasm injury following head trauma. The main visual defect associated is bitemporal hemianopia with macular splitting; however, it can present with a variety of other visual defects and neurologic signs. The authors report a case of complete bitemporal hemianopia after head trauma, with multiple frontal and skull base fractures and no other neurologic deficits, or hypothalamic-pituitary abnormality. Most cases of traumatic chiasmal syndrome are […]

ABSTRACT Ocular toxoplasmosis frequently presents as necrotizing retinochoroiditis and, less often, as peripapillary chorioretinitis and/or papillitis. The progression from papillitis to peripapillary retinochoroiditis has been rarely described. We report the case of a 52-year-old patient living in southern Brazil, who developed papillitis in the right eye and was treated with systemic corticosteroids (prednisone 0.6 mg/kg/day and pulse therapy with methylprednisolone 15 mg/kg/day, for 3 days). After 14 days, the patient developed peripapillary retinochoroiditis with vitritis and decreased visual acuity (20/60), […]

ABSTRACT Acute ocular hypertension during hemodialysis is a rare event and may lead to interruption of dialytic therapy due to pain. A case of a 70-year-old male patient is reported, who presented recurrent intense unilateral ocular pain episodes during dialysis sessions for increased intraocular pressure. The patient presented with severely decreased visual acuity in the right eye due to neovascular glaucoma, which was controlled with topical hypotensive medication. One hour after initiating dialysis, he presented an excruciating pain on the […]

Best-corrected visual acuity was initially 20/200. Upon examination, ciliary injection, mild corneal edema; fine keratic precipitates, and significant anterior chamber reaction. There was no vitritis, and […]

ABSTRACT We present a case of SARS-CoV-2 conjunctivitis in a 55-year-old female patient, with hyperemia and foreign body sensation in both eyes. The eye examination revealed conjunctivitis. She had detectable SARS-CoV-2 by polymerase chain reaction on conjunctival and nasal swabs. She was treated with ciprofloxacin eye drops, corticosteroids and trometamol for 5 days. After the seventh day of evolution, there was a significant improvement in conjunctivitis, and repeated conjunctival swab was negative.

ABSTRACT Exudative retinal detachment occurs when fluid accumulates between the neurosensory retina and the retinal pigment epithelium. Ocular diseases or multisystem conditions such as nephrotic syndrome may lead to exudative retinal detachment. This report describes a case of nephrotic syndrome secondary to minimal change disease, anasarca and bilateral serous macular detachment in an adult patient. A 75-year-old male patient presented to the emergency department with generalized edema, asthenia, and visual impairment. Medical history included a recent diagnosis of nephrotic syndrome […]

ABSTRACT The term dysfunctional lens syndrome has gained acceptance in the field and encompasses natural changes due to aging of crystalline lens. The evolution of diagnostic devices has been a key factor in better staging, understanding and characterizing of these degenerative changes. Even with these technological advances and the use of subjective classifications, such as the classic Lens Opacities Classification System, an objective staging of early dysfunctional lens syndrome has yet to be established. Ocular wavefront aberrometry and objective scatter […]
