ABSTRACT This study shows a case report of Mooren’s ulcer with a presumptive diagnosis, established by exclusion, occurring after pterygium surgery in a young patient with preexisting cutaneous autoimmune disease. This case report was based on comprehensive clinical evaluation, laboratory testing, microbiological cultures, PCR for infectious agents, and serial AS-OCT documentation, with the purpose of excluding known infectious and systemic etiologies. Therapeutic management included fortified antibiotics, tectonic support with a therapeutic contact lens and fibrin glue, followed by systemic immunosuppression […]

A 34-year-old man presented with pain and blurring vision in the right eye for 24 hours. The best-corrected visual acuity was 9/10 in the right eye. Slit-lamp examination of the right eye revealed conjunctival injection, three white granulomatous corneal precipitates (), one of them behind a stromal infiltrated area. A white tyndall effect in the anterior chamber at one cross and ocular hypertension at 50 mmHg were noticed. Gonioscopy shows a 360° open angle with a flat iris insertion root. […]

ABSTRACT Objective: To identify corneal epithelial thickness profiles for early keratoconus diagnosis with the aid of Artificial Intelligence. Methods: A total of 496 eyes (306 normal and 190 with keratoconus) were analyzed using optical coherence tomography images. Results: Epithelial segmentation revealed distinct patterns between groups, highlighting early changes in epithelial thickness in keratoconus eyes. The findings reinforce the potential of artificial intelligence in disease screening, enabling a more precise and objective diagnostic approach. Conclusion: Implementing algorithms such as k-means can […]

ABSTRACT Objective: To characterize structural optic nerve changes in Ecuadorian glaucoma patients using optical coherence tomography data from 2015 to 2022. Methods: This retrospective study analyzed anonymized optical coherence tomography data from 301 eyes of 162 patients diagnosed with primary open-angle glaucoma. Data were acquired using the Nidek RS-330 and analyzed with Statistical Package for the Social Sciences, version 21. We assessed peripapillary retinal nerve fiber layer thickness (global, quadrants, and clock-hour sectors) and cup-to-disc ratios. Results: The mean global […]

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 […]
