Indocyanine Green Angiography in Congenital Hypertrophy of the Retinal Pigment Epithelium
2017
PURPOSE To report a case of congenital hypertrophy of the retinal pigment epithelium followed up for 7 years showing features not previously reported. METHODS A complete fundus examination including fluorescein angiography was performed at first examination and at follow-up. RESULTS The area of congenital hypertrophy of the retinal pigment epithelium presented morphologic changes, showing enlargement of the lesion on one side associated with partial regression on another side. In addition, the indocyanine green angiography findings revealed that this test was more useful than fluorescein angiography to delineate the real boundaries of the lesion and disclosed hypofluorescent areas inside th…
ApoB100,LDLR-/- mice exhibit reduced electroretinographic response and cholesteryl esters deposits in the retina
2008
International audience; PURPOSE. To evaluate the retinal phenotype of 7- and 14-month-old apoB100,LDLR–/– mice, a relevant animal model of lipid metabolism dysfunction. METHODS. Single-flash electroretinograms were obtained from 7- and 14-month-old apoB100,LDLR–/– and control mice fed a standard diet under both scotopic and photopic conditions. Visual cycle retinoids were analyzed in eyes from dark-adapted mice. Retinal and choroidal vascularization was evaluated with scanning laser ophthalmoscopy. Fatty acids were analyzed in the retina. Esterified and free cholesterol was detected in eye cryosections. RESULTS. Scotopic and photopic b-wave amplitudes were significantly reduced in apoB100,L…
The Heidelberg retina tomograph ancillary study to the European glaucoma prevention study: study design and baseline factors.
2013
Purpose: To describe the study design and baseline factors of the Heidelberg Retina Tomograph ancillary study within the EGPS. Furthermore, to examine the relationship between HRT optic disc topographic measurements and baseline demographic and ocular factors. Methods: Four hundred and eighty-nine ocular hypertensive participants were included. Each participant completed HRT imaging at least annually. The associations between HRT measurements and IOP, central corneal thickness (CCT), baseline photographic estimates of vertical CDR ratio (CDR), asymmetry between the two eyes in CDR ratio and baseline visual field indices were assessed using regression analysis. Results: Associations between …
Switching from a preserved to a preservative-free prostaglandin preparation in topical glaucoma medication.
2010
. Purpose: The purpose of this study was to investigate the tolerability and intraocular pressure (IOP) reducing effect of the first preservative-free prostaglandin tafluprost (Taflotan®) in patients exhibiting ocular surface side-effects during latanoprost (Xalatan®) treatment. Methods: A total of 158 patients were enrolled in this open-label multicentre study. Eligible patients had to have at least two ocular symptoms, or one sign and one symptom, during treatment with latanoprost. At baseline, the patients were directly switched from latanoprost to preservative-free tafluprost for 12 weeks. The patients were queried for ocular symptoms, and ocular signs were assessed by using tear brea…
Usefulness of microalbuminuria in cardiovascular risk stratification of essential hypertensive patients
2004
<i>Background/Aims:</i> To evaluate the influence of microalbuminuria (albumin excretion rate – AER) determination and echocardiography (ECHO) on cardiovascular risk stratification, initially performed according the 1999 WHO/ISH guidelines by using only routine diagnostic procedures with or without fundal examination. <i>Methods:</i> 312 essential hypertensives attending our institution were studied retrospectively. Cardiovascular risk was assessed in a semiquantitative way using four categories of absolute cardiovascular disease risk (low, medium, high and very high risk), as proposed by the 1999 WHO/ISH guidelines, on the basis of data on the average 10-year risk o…
Visual and Refractive Outcomes in Hyperopic Pseudophakic Patients Implanted with the Acri.LISA 366D Multifocal Intraocular Lens
2009
Our purpose was to assess the visual quality after bilateral implantation of the Acri.LISA 366D intraocular lens (IOL; Carl Zeiss Meditec, Jena, Germany) in patients with hyperopia. We did a prospective and nonrandomized study. One hundred and seventy eyes of 85 patients had bilateral implantation of the Acri.LISA 366D IOL. The patients were divided into 2 groups: low to moderate hyperopia (IOL power, 21 to 24.5 diopters [D]) and high hyperopia (IOL power, 25 to 36 D). Monocular and binocular best spectacle-corrected visual acuity (BSCVA), best distance-corrected near visual acuity (BCNVA), binocular best distance-corrected intermediate visual acuity (VA), and distance contrast sensitivity …
Intereye Spatial Relationship of Abnormal Neuroretinal Rim Locations in Glaucoma Patients from the Diagnostic Innovations in Glaucoma Study
2006
Purpose To determine the spatial relationship in neuroretinal rim parameter values between eyes in ocular hypertensives, glaucoma suspects, and glaucoma patients. Design Observational-cross-sectional study. Methods A total of 334 eyes of 167 patients were included. All patients underwent confocal scanning laser ophthalmoscopy imaging in both eyes. Intereye concordance ratio of abnormal rim sectors as classified by the Moorfield regression analysis (MRA) was calculated as the ratio of matching abnormal rim areas to the total number of abnormal rim areas. The amount of agreement was calculated for each sector separately. Results Of the right (left) eyes, 39 (39) eyes were classified “borderli…
INTRAVITREAL BEVACIZUMAB FOR CHOROIDAL NEOVASCULARIZATION IN AGE-RELATED MACULAR DEGENERATION: 5-Year Results of The Pan-American Collaborative Retin…
2016
To report the long-term anatomical and functional outcomes of patients with choroidal neovascularization secondary to age-related macular degeneration treated with intravitreal bevacizumab (IVB).Retrospective case series. Patients diagnosed with subfoveal choroidal neovascularization secondary to age-related macular degeneration that were treated with at least 1 intravitreal injection of 1.25 mg of IVB and had a minimum follow-up of 60 months. Patients underwent best-corrected Snellen visual acuity testing, optical coherence tomography, and ophthalmoscopic examination at baseline and follow-up visits.Two hundred and forty-seven consecutive patients (292 eyes) were included. The mean number …
Clear Lens Extraction with Multifocal Apodized Diffractive Intraocular Lens Implantation
2007
Purpose To assess efficacy, safety, predictability, and stability after clear lens extraction (CLE) with multifocal diffractive intraocular lens (IOL) implantation. Design Prospective, nonrandomized, masked observational case series (self-controlled). Participants Two hundred twenty-four eyes of 112 consecutive patients after CLE with bilateral AcrySof ReSTOR Natural IOL implantation. Eyes were divided into myopic (mean spherical equivalent [SE], −6.01±2.71 diopters [D]) and hyperopic (mean SE, +3.86±2.52 D) groups. Methods Monocular and binocular uncorrected distance visual acuity (VA), best-corrected distance VA, uncorrected distance near VA, and best distance-corrected near VA were recor…
Branch retinal vein occlusion associated with the 20210 G-to-A prothrombin variant.
2000
Purpose To describe a case of branch retinal vein occlusion (BRVO) in a patient who tested positive for the 20210 A allele of the prothrombin (PT) gene. Methods A 48-year-old man had visual loss in the right eye secondary to BRVO confirmed by ophthalmoscopy and fluorescein angiography. His medical history was not remarkable for common risk factors for retinal occlusive diseases. Results Laboratory tests for hypercoagulability were positive for PT 20210 A variant. The patient's family tested negative for the PT variant. Conclusions Laboratory tests for coagulopathy, including the PT 20210 A variant, should be added to the examination of patients with central or BRVO, especially if most commo…
