The association between the growth of geographic atrophy (GA) and a single nucleotide polymorphism (SNP) in the complement factor I (CFI) locus was investigated in the COMPLETE trial. Growth of GA at 52 weeks in eyes without the CFI at-risk allele was slightly faster than the growth in eyes with the CFI at-risk allele (P ≥ .72).

Patients And Methods: Subfoveal CT measurements obtained from patients with AMD enrolled in the COMPLETE study (30 drusen-only eyes and 30 eyes with geographic atrophy [GA]) were compared with an age-distributed normal control group. Multimodal images were evaluated to detect the presence of RPD.

Background And Objective: To compare the measurements and growth rates of geographic atrophy (GA) secondary to age-related macular degeneration (AMD) obtained using different imaging modalities.
Patients And Methods: Thirty patients with AMD and GA measuring from 1.25 mm² to 18 mm² based on spectral-domain optical coherence tomography (SD-OCT) fundus imaging were enrolled.

Background And Objective: To evaluate subfoveal choroidal thickness (CT) and the extent of outer retinal disruption in patients with macular telangiectasia type 2 (MacTel2) compared with healthy eyes.
Patients And Methods: In this prospective, observational, cohort study, 62 patients (62 eyes) with Mac-Tel2 and 130 healthy controls (130 eyes) underwent a complete ophthalmological examination, spectral-domain optical coherence tomography (SD-OCT) imaging, and axial length measurements. Patients in the study group also underwent color fundus photography, fundus autofluorescence, and fluorescein angiography.
Purpose: To investigate the relationship between drusen areas measured with color fundus images (CFIs) and those with spectral-domain optical coherence tomography (SDOCT).
Methods: Forty-two eyes from thirty patients with drusen in the absence of geographic atrophy were recruited to a prospective study. Digital color fundus images and SDOCT images were obtained at baseline and at follow-up visits at 3 and 6 months.
Background And Objective: To evaluate the change in drusen volume following treatment with eculizumab, a systemic inhibitor of complement component 5.
Patients And Methods: Single-center, prospective, randomized, double-masked clinical trial. Patients were randomized 2:1 to receive intravenous eculizumab or placebo over 26 weeks.
Purpose: To evaluate the effect of eculizumab, a systemic inhibitor of complement component (C5), on the growth of geographic atrophy (GA) in patients with age-related macular degeneration (AMD).
Design: Prospective, double-masked, randomized clinical trial.
Participants: Patients with GA measuring from 1.
Purpose: To evaluate drusenoid retinal pigment epithelial detachments (DPED) secondary to age-related macular degeneration (AMD) using spectral-domain optical coherence tomography imaging.
Methods: In this prospective natural history study, eyes from patients with the diagnosis of nonexudative AMD and DPEDs were followed for at least 6 months. Eyes were scanned using the Cirrus spectral-domain optical coherence tomography instrument and the 200 × 200 A-scan raster pattern.
Vascularized retinal pigment epithelium detachments (PEDs) are part of the spectrum of neovascular age-related macular degeneration (AMD). These patients with vascularized PEDs are at a higher risk of experiencing severe vision loss. This case report demonstrates the use of a new spectral-domain optical coherence tomography (SD-OCT) algorithm to measure the area and volume of PEDs.

Methods: Patients with vascularized PEDs undergoing SD OCT-guided treatment with anti-vascular endothelial growth factor drugs were retrospectively identified. The decision to retreat these cases was based on qualitative assessments of fluid in the macula.

Diffuse unilateral subacute neuroretinitis (DUSN) is a usually unilateral inflammatory disease characterized by an insidious, usually severe loss of peripheral and central vision. Clinical characteristics are manifested in early and late stages. Parasites of different sizes and several species of nematodes have been reported as the etiology of DUSN without conclusive evidence about the specific agent.

Design: Retrospective study performed at the Federal University of Rio Grande do Norte, Rio Grande do Norte, Brazil, between 2003 and 2008.
Methods: Patients with early- or late-stage diffuse unilateral subacute neuroretinitis were included.
Purpose: To measure retinal nervous fiber layer (RNFL) thickness using OCT3 (Carl-Zeiss) in patients with diffuse unilateral subacute neuroretinitis (DUSN) with or without live worm and correlate it with visual acuity.
Methods: RNFL thickness, using RNFL thickness 3.4 program and best corrected visual acuity were measured in patients with DUSN between January 2005 and December 2006.
Choroidal neovascularization is a very rare complication in intermediate uveitis. A 27-year-old female patient diagnosed with intermediate uveitis two years ago. She presented with 20/200 visual acuity, snowballs, snowbanks, and macular cystoid edema in the right eye observed by fluorescein and optical coherence tomography (OCT).
View Article and Find Full Text PDFPurpose: To describe retinal nerve fiber layer changes in late-stage diffuse unilateral subacute neuroretinitis eyes and compare these results with healthy eyes observed through nerve fiber analyzer (GDx).
Methods: This is a retrospective case-control study in which 49 eyes in late-stage diffuse unilateral subacute neuroretinitis were examined from May/97 to December/01. First, eyes with diffuse unilateral subacute neuroretinitis and healthy contralateral eyes (Control Group I) were statistically matched.

Objective: To determine the prevalence of systemic and ocular toxoplasmosis among 1024 students in the city of Natal, Northeastern Brazil, and correlate it with demographic, socioeconomic and epidemiological risk factors.
Methods: The study population was randomly selected, asked to fill out a questionnaire, provide a blood sample for IgG and IgM (MEIA) serology and a hemogram, and undergo an eye examination.
Results: The seroprevalence for IgG was 46% (95% CI = 42.
