ABSTRACT Objective: To retrospectively evaluate the influence of intracorneal ring thickness on reduction of corneal astigmatism in patients with keratoconus. Methods: From a database of 2,033 eyes submitted to corneal ring implant surgery, a sample of 90 eyes with similar keratometry and astigmatism characteristics was selected. All eyes in this study received two segments of traditional arc length of approximately 160°, with varying thicknesses: Group A received two segments of 150 µm; Group B received two segments of 200 µm, […]

ABSTRACT The case of a 55-year-old male who presented central retinal vein occlusion with marked macular ischemia in left eye is reported. Despite the intervention with sustained-release dexamethasone polymer injection and other clinical measures, the visual acuity was severely reduced in left eye. After 8 months, he returned to the emergency with acute visual loss of 2 hours of progression in right eye due to a central retinal artery occlusion, sparing only the territory of the cilioretinal artery. Patient underwent […]

ABSTRACT To describe the prevalence of risk factors for retinopathy of prematurity and respective stages. Retrospective data were extracted from original articles addressing risk factors for retinopathy of prematurity retrieved from Scientific Electronic Library Online (SciELO), Virtual Health Library (VHL) and National Library of Medicine – NLM (PubMed) databases. In the initial search, 186 articles were found. Following title and abstract reading and application of inclusion and exclusion criteria, 25 articles were selected for this analysis. Variables of interest varied […]

ABSTRACT Objective: To analyze the clinical profile of patients under dermatological care and referred to ophthalmological evaluation. Methods: The sample comprised dermatology patients referred to ophthalmological evaluation in 2016 and 2017. The simultaneous occurrence of skin and ophthalmic diseases was studied, by collecting dermatological history (medical records containing general data and diagnosis) and ophthalmic consultation data following referral. Results: A total of 224 patients were assessed, 65% were female, 80% were white, and age varied between one month and 85 […]

ABSTRACT The iris is responsible for eye color and controls the amount of light that enters the eye through the pupil. Variation in each individual’s genes, besides the quantity and quality of melanin in the iris, determine eye color. Heterochromia is characterized by different colors of irises in the same individual, and it is benign in most cases. There are basically three types of heterochromia: central, partial and complete. Heterochromia can be caused by genetic and congenital alterations, which may […]

ABSTRACT Objective To identify preoperative clinical characteristics of patients undergoing femtosecond laser-assisted anterior lamellar keratoplasty who failed to achieve optimal postoperative visual outcomes. Methods In this single-center, retrospective case series, patients who underwent femtosecond laser-assisted anterior lamellar keratoplasty between 2013 and 2018 were included if they required graft revision, subsequent corneal procedure, or additional postoperative visits for a femtosecond laser-assisted anterior lamellar keratoplasty-related issue. Visual outcomes assessed included best-corrected visual acuities and postoperative corneal astigmatism. Results Eight eyes of eight […]

Religion/spirituality (R/S) is very important to most patients, with 84% of world’s population reporting a religious affiliation. Even those with no religion often report some level of spirituality, which may be defined as “the relationship or contact with a transcendent realm of reality [e.g., God, gods, spirits, deceased ancestors, etc.] that is considered sacred, the ultimate truth, or reality” (p.12).() Religion would be the “the institutional or communal aspect of spirituality, as a shared set of beliefs, experiences, and practices […]

ABSTRACT Objective: To assess effectiveness of fundus photography and fluorescein angiography in diagnosis and screening of diabetic retinopathy. Methods: A retrospective study of 398 diabetic patients, based on analysis of results of both tests. Results: Results of fluorescein angiography and fundus photography coincided in 77.4% of cases, and there was no significant difference in staging and identification of retinopathy by both methods. Conclusion: There was no significant difference between both methods regarding the capacity to diagnose the disease, showing no […]
