ABSTRACT Purpose: To assess the agreement between IOLMaster 500 and Argos for ocular biometry parameters Methods: This retrospective study included 104 patients (205 eyes) who underwent biometry with both devices. Measurements included axial length (AL), keratometry (K1, K2), and ACD. Anterior chamber depth (ACD) measurements were compared directly as reported by each device, without additional correction for corneal thickness. Results: No significant differences were found for AL (23.49 ± 1.29 mm versus 23.63 ± 1.35 mm; p = 0.737), K1 […]

ABSTRACT Objective: To evaluate the agreement between the Eyestar900 and IOLMaster700 for biometric measurements and assess their interchangeability. Methods: This retrospective study analyzed the following parameters: anterior keratometry, axial length, anterior chamber depth, white-to-white diameter, and lens thickness. Agreement was assessed using intraclass correlation coefficients, Bland-Altman plots, and scatter plots. A paired t-test was used to evaluate statistical differences. Results: A total of 43 eyes from 33 patients were analyzed. The mean differences were 0.03 D for keratometry, 0.08 mm […]

ABSTRACT Objective: To assess the diagnostic accuracy of ChatGPT in analyzing OCT images. Methods: A total of 300 OCT images, previously interpreted by specialists, were analyzed by ChatGPT under three scenarios: image-only input; input with additional epidemiological data; and input with detailed clinical data. Sensitivity, specificity, and accuracy rates were compared across scenarios using appropriate statistical analyses (p < 0.05). Results: Overall accuracy was 66.33% in the image-only scenario, 82.33% with epidemiological data, and 92.67% with clinical data. Sensitivity for [...]

ABSTRACT Myelinated retinal nerve fibers are rare congenital anomalies that appear as gray-white patches. They may be present in a syndrome characterized by ipsilateral myelinated retinal nerve fibers, myopia and amblyopia. The author reported an ellipsoid zone defect on spectral domain optical coherence tomography in a case of Straatsma syndrome without macular extension.

ABSTRACT Dome-shaped macula consists of the convex elevation of the macular region, found mainly in patients with high myopia. The clinical significance and the correlation with other ocular pathologies are still uncertain. This article aims to describe two cases of dome-shaped macula with accumulation of subretinal fluid in high myopic eyes. Those are patients with low visual acuity, myopic fundus and a clear dome-shaped elevation in the macular area at optical coherence tomography. A dome-shaped macula can course with a […]

ABSTRACT We present the case of a patient with an optic disk pit, presenting with great loss of visual acuity secondary to serous retinal detachment. The management chosen was an intravitreal injection of 0.3 mL of C3F8 (100%), followed by argon laser photocoagulation on the temporal edge of the pit, ), achieving total retinal reattachment , and reabsorption of all subretinal fluid visible at optical coherence tomography after 400 days, in addition to great improvement in visual acuity.

Multifocal choroiditis is an uncommon idiopathic inflammatory ophthalmological disease, which usually affects young women. The authors report a case of multifocal choroiditis in which patient underwent subtenonian triamcinolone injection associated with oral corticosteroid and management of immunosuppressive therapy. The clinical, diagnostic and treatment aspects are discussed. The subtenonian triamcinolone injection presented good results on macular edema when associated with oral imunosuppressive therapy, in agreement with the records obtained in the current medical literature.

The spontaneous closure of a full-thickness macular hole (MH) developed after vitrectomy is very uncommon. We report a small series of cases (two patients) with this presentation. The first patient developed a MH 1 month after vitrectomy for an epirrretinal membrane and, the second one, 3 weeks after vitrectomy for rhegmatogenous retinal detachment. The MHs resolved spontaneously 2 months and 1 month after their documentation by optical coherence tomography(OCT), respectively. In this case report, we review the literature on spontaneous […]
