ABSTRACT Objective: To evaluate parents’ knowledge and perceptions about amblyopia and its treatment after their child’s diagnosis. Methods: A cross-sectional study included parents of 30 children diagnosed with amblyopia, recruited from a pediatric ophthalmology clinic. Participants completed a questionnaire after the diagnosis of their children, before receiving amblyopia education. The questionnaire assessed parental knowledge, socioeconomic background, and barriers to care. Statistical analyses included descriptive statistics and logistic regression to identify factors associated with awareness and adhesion. Results: Most parents (85.7%) […]

ABSTRACT Objective: To assess the mental health status of patients diagnosed with keratoconus in the city of Porto Alegre (RS). Methods: A prospective cross-sectional study with a sample of 106 patients. The study was conducted at the Ophthalmology Department of the Hospital de Clínicas de Porto Alegre, in the Contact Lens and Corneal Transplant sectors. The Patient Health Questionnaire-9 was used, and the results were described categorically or continuously, in percentages and means/medians, as indicated. Results: The prevalence of depressive […]

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 […]
