ABSTRACT Objective: To determine the prevalence of blindness in elderly people from quilombola communities located in the immediate geographic region of Araguaína, in the north of Tocantins. Methods: A cross-sectional study was carried out, in which 80 residents, aged 60 or over, from 4 certified quilombola communities in this region were examined: Pé do Morro, Baviera, Dona Juscelina, and Cocalinho. Everyone answered a questionnaire on demographic and socioeconomic variables, and underwent a visual acuity exam, using the Snellen Table. For […]

ABSTRACT Ligneous conjunctivitis is a rare chronic disease described as membranous keratoconjunctivitis that may be associated with systemic manifestations. It is associated with congenital plasminogen deficiency. In this case report, we describe the case of a 3-year-old male child who was diagnosed with ligneous conjunctivitis that mimicked gonococcal conjunctivitis after secondary infection with Streptococcus pyogenes. The patient had a bilateral pre-tarsal conjunctival membrane and a fibrous membrane extremely adherent to the corneal epithelium in the left eye, associated with intense […]

ABSTRACT This study aims to report the case of a patient with Multiple Sclerosis (MS) and investigate the relationship between hypovitaminosis C and the development of the disease, as well as evaluate the impact of vitamin C supplementation on controlling clinical symptoms. A 21-year-old male patient diagnosed with MS, presenting visual complaints and a relevant family history. The investigation included clinical, laboratory, and imaging exams, identifying hypovitaminosis C. The treatment consisted of prednisone administration and vitamin C supplementation. Vitamin C […]

Vision impairment is considered a global health concern, as around 246 million people worldwide have low vision.() In remote areas, the lack of access to an ophthalmologist and the absence of diagnostic technology from urban centers have a negative impact on the screening and monitoring of various eye diseases.(,) In this sense, our team conducted an eye care taskforce in November 2024, in the archipelago of Fernando de Noronha, located approximately 350 kilometers off the Brazilian coast, in the State […]

ABSTRACT Objective: To evaluate refractive and topographic outcomes before and at least 7 years after intrastromal ring segment implantation surgery in patients with keratoconus. Methods: Long-term retrospective longitudinal study carried out with 35 patients (62 eyes) aged 10 to 30 who underwent intrastromal ring segment implantation using a manual technique. Different arc rings were analyzed across various keratoconus types. Results: Significant improvements in topographic astigmatism (p = 0.001) and corrected distance visual acuity (p < 0.001) were observed, with no [...]

ABSTRACT Objective: To evaluate the effect of pterygium on different biometric intraocular lens calculation formulas. Methods: This is an interventionist, prospective, and non-randomized study. We included patients who underwent pterygium surgery and performed a biometric examination before and one month after surgery. We compared the mean variability between these measurements in each intraocular lens formula. We classified the patients according to the TAN staging system and evaluated the effect of pterygium magnitude on biometric variability. Results: We included 25 eyes […]

ABSTRACT Case report of a 14-year-old male presented with acute painless vision loss and left optic disc swelling. Extensive diagnostic investigations, including magnetic resonance imaging and serum MOG antibody testing, were conducted. Magnetic resonance imaging showed an extensive T2 hyperintense signal in the anterior portion of the left optic nerve without involving chiasm or retrochiasmatic areas. The management strategy involved intravenous methylprednisolone followed by azathioprine, resulting in complete vision recovery. This case highlights the importance of considering MOG antibody-associated optic […]
