ABSTRACT Objective: To evaluate the tomography accuracy of Cirrus 5000 optical controls in patients with or without keratoconus for pachymetry measurements by image scanning patterns. Methods: A prospective, cross-sectional and mixed study was performed in 20 eyes, where 37 parameters of each sample was analyzed and repeated 5 times. Results: Only four samples (vertex full, maximum epithelial pachymetry at 5 to 7.0mm, maximum epithelial pachymetry at 7 to 9.0mm and epithelial pachymetry difference between minimum and average) samples showed a […]

Anterior segment-optical coherence tomography (AS-OCT) imaging provide a range of characteristic patterns that could be used as an additional tool in the diagnosis and management of infectious keratitis.(,) We describe the AS-OCT findings of a patient with fungal keratitis. A 65-year-old man with a history of vegetal trauma to his left eye, presented to the emergency room complaining of pain and blurred vision in the right for three weeks. The best corrected visual acuity was 3/10 in the left eye. […]

ABSTRACT The pachychoroid disease spectrum (PDS) encompasses a range of chorioretinal disorders characterized by increased choroidal thickness, dilated Haller’s layer vessels (pachyvessels), and choroidal hyperpermeability, often associated with retinal pigment epithelium (RPE) alterations. This review synthesizes current evidence on pachychoroid pigment epitheliopathy (PPE), central serous chorioretinopathy (CSC), pachychoroid neovasculopathy (PNV), and polypoidal choroidal vasculopathy (PCV), emphasizing their shared pathophysiological mechanisms, multimodal imaging features, and clinical implications. Enhanced depth imaging optical coherence tomography (EDI-OCT) and widefield indocyanine green angiography (ICGA) have […]

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 This article is aimed at documenting a case of Bergmeister papilla that was an incidental finding that had its conclusive diagnosis given by the optical coherence tomography (OCT) of the optic nerve and retinography. We report the case of a female patient who came to our service for a routine appointment claiming visual difficulty seeing from a distance in both eyes. After the appointment and the request of the diagnostic tests, Bergmeister Papilla was found in the right eye, […]

ABSTRACT Congenital stationary night blindness encompasses a heterogeneous group of inherited retinal dystrophies characterized by impaired scotopic vision from birth. This article provides a comprehensive overview of congenital stationary night blindness, focusing on its genetic underpinnings, clinical manifestations, and diagnostic approaches, with a specific emphasis on variants in the CACNA1F gene. Through a detailed case report of a 49-year-old male with congenital stationary night blindness attributed to a hemizygous variant in CACNA1F, we illustrate typical clinical presentations and correlate them […]

ABSTRACT To report a case of Terson syndrome following a traumatic brain injury during a footvolley match. The patient was undergoing evaluation with the following tests: visual acuity, retinography, angiography, and optical coherence tomography. Follow-up was maintained for 3 months with conservative treatment. Terson syndrome associated with head trauma is poorly documented as fundoscopy is not performed in most patients.

ABSTRACT Occult macular dystrophy is characterized by a slowly progressive bilateral reduction of visual acuity in patients with normal fundus and fluorescein angiography. We describe a case of a 36-year-old male patient diagnosed with this condition, after extensive investigation with multimodal imaging, electrophysiology tests, and systemic screening.
