ABSTRACT Objective: To evaluate the agreement of biometric parameters measured by the ANTERION and IOLMaster700 devices in a Brazilian population, considering statistical differences and their clinical relevance. Methods: A retrospective comparative study included cataract patients who underwent biometric examination with ANTERION and IOLMaster700 between September and December 2023. The parameters evaluated were anterior keratometry, axial length, central corneal thickness, anterior chamber depth, white-to-white diameter, and lens thickness. Agreement and correlation were assessed using Bland-Altman and scatter plots. Results: A total […]

ABSTRACT Background: Trabeculectomy is a common surgical technique performed when clinical treatments are not enough to control glaucoma. Prolonged use of eye drops to control intraocular pressure (IOP) can lead to ocular surface disease, negatively affecting postoperative results. Objective: This article aimed to analyze the current literature on the effects of preoperative preparation for trabeculectomy with topical corticosteroids on surgical outcome and postoperative intervention. Methods: A systematic review that followed PRISMA guidelines was performed, and articles were searched at PubMed, […]

ABSTRACT This case series evaluates the visual outcomes of two trifocal intraocular lenses, the ZFR00V and TNFT00, in cataract surgery patients. Nineteen patients (38 eyes) were bilaterally implanted with one of the two intraocular lenses. Postoperative assessments included uncorrected and corrected distance, intermediate, and near visual acuities, as well as patient-reported satisfaction and photic phenomena. Both intraocular lenses provided satisfactory visual performance for distance and intermediate vision. However, the ZFR00V intraocular lenses demonstrated superior near vision, particularly in the defocus […]

We present the case of an 80-year-old patient diagnosed with severe pseudoexfoliation syndrome (PEX) in both eyes (OU), who underwent uneventful bilateral phacoemulsification with in-the-bag intraocular lens (IOL) implantation 10 years ago. However, 4 years postoperatively, the patient developed subluxation of the capsular bag-IOL complex in the left eye, attributable to the progressive zonular insufficiency characteristic of PEX. Consequently, the subluxated IOL was removed, and an iris-fixated lens was implanted. During follow-up, 6 years after the initial surgery, a similar […]

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 […]

ABSTRACT Choroidal metastasis is the most common intraocular malignancy. However, bilateral involvement remains exceptionally rare. We describe a case of a 57-year-old patient with no comorbidity who presented with progressive decrease in visual acuity of both eyes for 5 months duration. Fundus examination of both eyes revealed choroidal masses in the posterior pole with serous retinal detachment. She did not exhibit any respiratory symptoms, and systemic examinations were normal. Systemic investigation including computed tomography thorax revealed patient had lung tumour […]

ABSTRACT Background: There is a debate regarding the differences in intraocular pressure values between different types of dispersive ophthalmic viscosurgical devices in patients after phacoemulsification for cataracts. Objectives: We aim to evaluate the differences between hydroxypropyl methylcellulose and sodium hyaluronate alone or combined with chondroitin sulfate as ophthalmic viscosurgical devices after phacoemulsification in selected patients related to intraocular pressure. Methods: We conducted a systematic review and meta-analysis of randomized clinical trial data comparing only dispersive hydroxypropyl methylcellulose with sodium hyaluronate […]

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 [...]
