ABSTRACT Optical coherence tomography is an imaging technique widely used in the diagnosis and monitoring of patients with age-related macular degeneration, being crucial for differentiating between the dry and exudative forms of the disease. The recognition and interpretation of various age-related macular degeneration biomarkers in optical coherence tomography play a key role in identifying signs of activity, chronicity, disease progression, and, most importantly, in monitoring the response to treatment and prognosis. Understanding the biomarkers enables the ophthalmologist to optimize their […]

ABSTRACT Objective: To evaluate the efficacy of high-dose oral riboflavin treatment combined with sun exposure in preventing the progression of keratoconus. Methods: A retrospective, multicenter observational study involving 53 keratoconus patients (106 eyes) from three Brazilian cities. Patients were instructed to take 400 mg/day of oral riboflavin and to sunbathe for 30 minutes daily, in addition to avoiding eye rubbing. Keratometric measurements were evaluated before and after 6, 12, 24, and 36 months of treatment. Results: After 6 months, 42 […]

ABSTRACT The rate of visual field progression is an essential factor in determining risk of visual disability or blindness in glaucoma patients. Knowledge of the rate of progression of a particular patient, in combination with an estimation of their longevity and other clinical factors, allows clinicians to optimize management by providing appropriately aggressive treatment. Despite decades of research on the treatment of glaucoma, the natural history of glaucomatous visual field progression in untreated and treated patients remains unclear. The purpose […]

Objective: To evaluate the clinical results of Transepithelial Crosslinking (CXL) by analyzing its efficacy in patients with progressive keratoconus. Methods: Retrospective cross-sectional study with 49 eyes and 37 patients aged 10 to 50 years submitted to the CXL technique in 2017 at the Instituto Panamericano da Visão, in Goiânia, Goiás, Brazil. The Avedro KXL system was programmed in pulsed mode with interval (1/1 second), using 45 mW/cm² with 7.2 J and 0.25% riboflavin solution of Avedro with irradiated corneas for […]
