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 […]

Corneal dystrophy is a hereditary non-inflammatory disorder in which substances accumulate in the cornea. A 32-year-old woman presented for routine ophthalmic examination. The patient has myopia of −6.25 in both eyes with best corrected visual acuity at 8/10 bilaterally. On slit-lamp examination, she was found to have crumb-like and star opacities, grey-white deposits in the anterior corrneal stroma (-). Clear areas were present between the opacities. The peripheral cornea was clear. Her best corrected visual acuity was 8/10 bilaterally. A […]

ABSTRACT Sickle cell disease is the most common hemoglobinopathy, and the perioperative period can be an exacerbation of the disease. The aim of this report is to describe the case of a patient with Sickle Cell Disease who underwent surgery to correct his strabismus and developed Acute Thoracic Syndrome, the most feared complication in patients with this disease. The adversities of this disease result from the sickling process of red blood cells, which can be triggered by cold, dehydration, and […]

ABSTRACT Objective: To identify the acute effect of resistance exercise on ocular perfusion pressure (OPP) in healthy individuals. Methods: The recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used. Searches were conducted in the databases: Medline, Embase, Cochrane, CINAHL, Web of Science, and Scopus. Studies that assessed OPP before and after physical exercise were included. The risk of bias was analyzed by the Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group. Random effect […]

ABSTRACT Objective: To analyze the ophthalmologic emergency care provided at a public hospital in Northern Minas Gerais. Methods: This is an analytical cross-sectional study. The data were obtained from medical records regarding ophthalmologic emergency care provided in 2022 at a public hospital in Northern Minas Gerais. Results: A total of 314 ophthalmologic consultations were evaluated, with traumatic injuries being the most frequent, accounting for 58.6% of cases. Foreign bodies were the most common cause of traumatic injury, and iron filings […]
