BACKGROUND: Although photodynamic therapy (PDT) has become the standard treatment for central serous chorioretinopathy (CSC), its mechanism of action remains unclear. It is assumed that PDT induces short-term choriocapillaris (CC) occlusion and long-term choroidal vascular remodeling. In this paper, we describe the short-term CC changes induced by Half-Dose PDT (HD-PDT) in chronic CSC using optical coherence tomography-angiography (OCTA). METHODS: This is a prospective interventional case series...

OBJECTIVE: Type 2 idiopathic macular telangiectasia (MacTel2) is a rare retinal disease that has still not been well-defined. The aim of the present manuscript is to describe the clinical features by multimodal retinal imaging, to present the functional characteristics, and to estimate the prevalence of the disease. METHODS: A retrospective study was conducted on the 12 eyes of 6 patients with MacTel2. Fundus colour photographs, fundus autofluorescence, fluorescein angiography, optical coherence tomography (OCT), and OCT-angiography were performed and subsequently analysed...

PURPOSE: To describe the features of peripapillary pachychoroid syndrome (PPS), a novel pachychoroid disease spectrum (PDS) entity. METHODS: Medical records of 31 eyes (16 patients) with choroidal thickening associated with intraretinal and/or subretinal fluid in the nasal macula extending from the disk were reviewed (patients with PPS). Choroidal thickness was compared with 2 age-matched cohorts: typical PDS (17 eyes with central serous chorioretinopathy or pachychoroid neovasculopathy) and 19 normal eyes...

PURPOSE: To report the findings in a patient with peripapillary pachychoroid pigment epitheliopathy who demonstrated a retinal pigment epithelial detachment (PED) that was present at some times but not other times.

A 12-year-old boy presented with best-corrected visual acuity (BCVA) of 6/9 in both eyes following an episode of electric shock. Optical coherence tomography (OCT) showed disruption of the ellipsoid zone as well as retinal pigment epithelium (RPE) layer. Fundus autofluorescence (FAF) showed increased central hypoautofluorescence in both eyes. At 3-month follow-up, BCVA improved to 6/6 with OCT showing spontaneous resolution of maculopathy in both eyes with reorganized RPE layer and ellipsoid zone. To the best of our knowledge, this is the first case of bilateral electric shock maculopathy (ESM) with spontaneous anatomical as well as functional recovery...

PURPOSE: To determine a reliable method of using the ellipsoid zone (EZ) on optical coherence tomography (OCT) to track disease progression in Stardgardt disease (STGD). DESIGN: retrospective reliability study METHODS: STGD patients with genetically confirmed ABCA4 gene mutations seen at the Wilmer Eye Institute with follow-up visits separated by at least 12 months were identified.

Torpedo maculopathy is a rare congenital anomaly of the retinal pigment epithelium (RPE). Various imaging modalities have been used to assess cases of torpedo maculopathy, including optical coherence tomography (OCT) and fundus autofluorescence (FAF). OCT angiography (OCTA) offers combined structural and flow characteristics of imaged lesions. The authors present OCTA findings in two cases of torpedo maculopathy. Common features include loss of RPE and choriocapillaris allowing greater visualization of larger vessels in the outer choroid...

Geographic atrophy (GA) is an advanced form of age-related macular degeneration (AMD) that leads to progressive and irreversible loss of visual function. Geographic atrophy is defined by the presence of sharply demarcated atrophic lesions of the outer retina, resulting from loss of photoreceptors, retinal pigment epithelium (RPE), and underlying choriocapillaris. These lesions typically appear first in the perifoveal macula, initially sparing the foveal center, and over time often expand and coalesce to include the fovea...

To report a case of bilateral isolated foveal hypoplasia in which multimodal imaging was used to confirm the diagnosis. Fundus autofluorescence imaging, optical coherence tomography (OCT), and fundus fluorescein angiography were used to describe the typical findings of a patient with isolated foveal hypoplasia. Spectral domain OCT showed absence of foveal depression and persistent inner retinal layers in the fovea. Fundus autofluorescence did not reveal foveal hypoautofluorescence in the presumed foveal area...

A 52-year-old male presented with a 25-year history of decreasing vision. Best corrected visual acuity was 0.3 in his right and 0.2 in his left eye. Fundoscopic examination showed bilateral symmetric atrophy of the retinal pigment epithelium and choriocapillaris in the posterior polar areas between vascular arcades and surrounding the optic disc. On fluorescein angiography, the large choroidal vessels beneath these affected regions were easily seen. Fundus autofluorescence imaging showed clearly defined hypoautofluorescent areas that corresponded to the aforementioned lesions...

PURPOSE: To investigate fundus autofluorescence (FAF) lifetimes in geographic atrophy (GA) with a focus on macular pigment (MP) and foveal sparing. METHODS: The study included 35 eyes from 28 patients (mean age 79.2 ± 8.0 years) with GA. A 30° retinal field, centred at the macula, was investigated using fluorescence lifetime imaging ophthalmoscopy (FLIO). The FLIO technology is based on a Heidelberg Engineering Spectralis system. Decays of FAF were detected in a short (498-560 nm, SSC) and long (560-720 nm, LSC) spectral channel...

PARTICIPANTS: Panel of retina specialists, image reading center experts, retinal histologists, and optics engineers. METHODS: As part of the Classification of Atrophy Meetings (CAM) program, an international group of experts surveyed the existing literature, performed a masked analysis of longitudinal multimodal imaging for a series of eyes with AMD, and reviewed the results of this analysis to define areas of agreement and disagreement...

Nonhuman primates are the only mammals to possess a true macula similar to humans, and spontaneously develop drusenoid lesions which are hallmarks of age-related macular degeneration (AMD). Prior studies demonstrated similarities between human and nonhuman primate drusen based on clinical appearance and histopathology. Here, we employed fundus photography, spectral domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), and infrared reflectance (IR) to characterize drusenoid lesions in aged rhesus macaques...

Fundus autofluorescence (FAF) is a non-invasive retinal imaging modality used in clinical practice to non-invasively map changes at the level of the retinal pigment epithelium (RPE)/photoreceptor complex and alterations of macular pigment distribution. This imaging method is based on the visualization of intrinsic fluorophores and may be easily and rapidly used in routine patient care. Excessive accumulation of lipofuscin granules in the lysosomal compartment of RPE cells represents a common downstream pathogenic pathway in various hereditary and complex retinal diseases...

PURPOSE: Pigment in the midretina is a characteristic sign in Type 2 idiopathic macular telangiectasia (MacTel) and is considered to characterize the late stage of the disease. Our aim was to investigate its incidence, and relationship with risk factors for MacTel, including outer retinal vascularization and subretinal neovascular proliferation (SRNV). METHODS: Pigment extent was measured in fundus autofluorescence images of 150 eyes of 75 MacTel probands, using the Region Finder tool of Heidelberg Eye Explorer...

PURPOSE: To detect, using multimodal imaging, lacquer cracks (LCs) and myopic stretch lines (MSLs) in pathologic myopic eyes with macular hemorrhage (MHE) and those without. METHODS: We collected 18 consecutive pathologic myopic eyes (spherical equivalent ≤ -8.0 diopters) that had presented with linear, yellowish-white lesions in the macula. We categorized the eyes into either the MHE group or the non-MHE group. All underwent fluorescein angiography (FA), near infrared autofluorescence (NIA), indocyanine green angiography (ICGA), and spectral-domain optical coherence tomography (SD-OCT)...

Purpose: Centripetal retinal degeneration in choroideremia (CHM) leads to early visual field restriction and late central vision loss. The latter marks an acute decline in quality of life but visual prognostication remains challenging. We investigated visual function in CHM by correlating best-corrected visual acuity (BCVA), microperimetry and multimodal imaging. Methods: Fifty-six consecutive CHM patients attending Oxford Eye Hospital were examined with BCVA, 10-2 microperimetry, optical coherence tomography, and fundus autofluorescence (AF)...
