ABSTRACT Objective: To evaluate the therapeutic response to brolucizumab in eyes with chronic neovascular age-related macular degeneration (nAMD) refractory to prior anti-angiogenic treatments. Methods: This prospective observational study included patients with chronic nAMD who maintained exudative neovascularization after at least three injections of ranibizumab and/or aflibercept without previous episodes of uveitis or vasculitis. Participants received one to three intravitreal injections of brolucizumab. Best-corrected visual acuity (BCVA) was assessed before and 4 weeks after each injection, along with analysis of fluid […]

A 35-year-old man presented to the ophthalmology clinic with immediate blurry vision and central scotoma in the right eye after sustaining accidental exposure to a handheld laser pointer (power < 1 mW, wavelength 640 to 660 nm; according to the label on the device) from approximately 5 m away, for a duration that he described as 1 to 2 seconds during a PowerPoint presentation in a conference room. Visual acuity was 20/80 in the right eye and 20/20 in the [...]

ABSTRACT Objective: To characterize the effectiveness of anti-vascular endothelial growth factor drugs in exudative age-related macular degeneration. Methods: Retrospective longitudinal study of 54 patients with age-related macular degeneration receiving bevacizumab or aflibercept. Demographic data, visual acuity, and central retinal thickness measurements were collected. Improvement/stability of visual acuity and reduction in retinal thickness configured satisfactory responses. Results: Among the 60 eyes studied, there was no difference (p = 0.262) in satisfactory response when using bevacizumab (48.5%) or aflibercept (63.0%). Snellen’s visual […]

ABSTRACT Objective: To determine the prevalence of ocular alterations in patients diagnosed with dengue, admitted to a reference center for infectious and parasitic diseases in Manaus (AM), Brazil. Methods: This was an observational, analytical, and prospective case series study with 33 patients admitted to the hospital with positive clinical pathology tests during a 90-day period of a dengue epidemic in 2011. The investigations included measurement of visual acuity, macular assessment with Amsler grid test, fundus biomicroscopy, retinography and optical coherence […]

ABSTRACT The characteristic optical coherence tomography finding in solar maculopathy is a well-defined outer retinal hyporeflective space primarily involving the photoreceptor inner and outer segment layers. This typical optical coherence tomography image may be present in a few other pathologies, which currently constitute their main differential diagnoses. Our study shows the report of 12 eyes of 6 patients treated at the Hospital de Olhos do Paraná, presenting their clinical history and diagnostic images, with the purpose of comparing the findings […]

ABSTRACT Objective: Age-related macular degeneration (AMD) is the most prevalent cause of irreversible visual loss in the developed world. In late stages, it may lead to extremely low visual acuities, especially when associated with geographic atrophy or choroidal neovascularization. According to recent literature, Charles Bonnet syndrome (CBS) may be a rather common feature of late AMD. Methods: One hundred patients with late-stage age-related macular degeneration were actively asked whether they had symptoms of Charles Bonnet syndrome. Those that answered positively […]

ABSTRACT Age-related macular degeneration is the most important cause of irreversible vision loss in the elderly and has been considered a severe public health problem. Current treatments have only been successful in delaying the loss of central vision. Due to increased life expectancy, governments and researchers have been challenged to seek more efficient and successful treatments for age-related macular degeneration. Considering its relevance for public health and the need of further research, this article aims to address age-related macular degeneration […]

ABSTRACT A 10-year-old Malay girl with underlying HbE/beta-thalassemia, on regular blood transfusion and deferoxamine iron chelation therapy, presented with two-month history of bilateral blurring of vision. On examination, her vision was 6/36 both eyes. Other optic nerve functions were normal. Anterior segment examination of both eyes was unremarkable. Fundus examination of both eyes revealed dull foveal reflex. Optical coherence tomography of both maculae showed increased central subfield thickness. Fundus fluorescence angiography showed patchy hypofluorescence over macular region for both eyes […]
