We report an unusual phenotype in a child with a clinical diagnosis of recessive Stargardt disease (STGD1) and two pathogenic variants in the ABCA4 gene. Typically, the diagnosis of early-onset STGD1 is challenging because children may present with a variety of fundus changes and a variable rate of progression. At the time of his initial visit, the 6-year-old boy presented with 20/200 OD (right eye) and 20/150 OS (left eye), symmetrical mild foveal atrophy without flecks on fundus exam, and foveal hypoautofluorescence surrounded by a homogeneous hyperautofluorescent background on wide-field fundus autofluorescence...

Purpose: The purpose of this study was to study the incidence and factors influencing retinal displacement in eyes treated for rhegmatogenous retinal detachment (RRD) with pars plana vitrectomy (PPV) and gas or silicone oil. Methods: This was a prospective observational case series. One hundred twenty-five eyes with macula-off RRD from 125 patients underwent 25-gauge PPV at two vitreoretinal institutional practices. Eyes without proliferative vitreoretinopathy (PVR) or PVR grade A were tamponated with sulfur hexafluoride (SF6) gas, whereas eyes with PVR grade B received 1000 centistokes silicone oil (SO)...

PURPOSE: To investigate the incidence and predictors of macular atrophy during treatment with aflibercept for neovascular age-related macular degeneration in Japanese patients. METHODS: This study included patients with treatment-naive subfoveal neovascular age-related macular degeneration treated from December 2012 through January 2015. Patients were treated with bi-monthly aflibercept injections after 3 monthly loading injections for the first year. Diagnosis of retinal pigment epithelial atrophy was made based on color fundus photography, spectral-domain optical coherence tomography, and fundus autofluorescence...

PURPOSE: To characterize autofluorescence (AF) patterns occurring in Stargardt macular dystrophy (STGD1) using ultra-wide-field (UWF) imaging. METHODS: This paper is a cross-sectional observational study of 22 eyes of 11 patients (mean age 23.44 years) with Stargardt disease-fundus flavimaculatus who presented with decrease of vision at a tertiary eye care center. UWF short-wave AF images were obtained from all the patients using an Optos TX200 instrument. The main outcome measures were to assess patterns of AF changes seen on UWF AF imaging...

A 54-year-old white man presented with a "blind spot" temporally in his left eye. Best-corrected visual acuity in the affected eye was 20/20 and Humphrey visual field revealed an enlarged blind spot. Funduscopic examination revealed subtle peripapillary pigmentary changes corresponding to a well-demarcated peripapillary region of hyper- and hypoautofluorescence on fundus autofluorescence (FAF). Outer retinal degenerative changes were detected on spectral domain optical coherence tomography (SD-OCT). A diagnosis of Acute zonal occult outer retinopathy (AZOOR) was made based on clinical history and imaging studies...

Autofluorescence images of the fundus have been part of the routine diagnostics of the human eye for almost two decades. Further development of imaging techniques makes fundus autofluorescence (FAF) imaging a safe, non-invasive, easy-to-perform and reproducible diagnostic tool. FAF uses the autofluorescent properties of tissues, in particular the retinal pigment epithelium (RPE) and its fluorophores. FAF images display phenomena of normal aging as well as disease-related changes of the fundus, but also can be used for monitoring retinal diseases and therapy...

PURPOSE: To assess the efficacy of photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC), in whom subretinal fluid (SRF) was solely present outside the foveal area. METHODS: In this retrospective study, 16 eyes of 15 cCSC patients who received half-dose PDT because of notable subjective visual complaints due to the presence of extrafoveal SRF, were included. An ophthalmic examination was performed before treatment, including Early Treatment Diabetic Retinopathy Study best-corrected visual acuity measurement, applanation tonometry, slit-lamp examination, and indirect ophthalmoscopy, followed by multimodal imaging, including fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography (OCT), enhanced-depth imaging OCT of the choroid, fluorescein angiography, and indocyanine green angiography...

REVIEW
Chantal Dysli, Sebastian Wolf, Mikhail Y Berezin, Lydia Sauer, Martin Hammer, Martin S Zinkernagel
Imaging techniques based on retinal autofluorescence have found broad applications in ophthalmology because they are extremely sensitive and noninvasive. Conventional fundus autofluorescence measures fluorescence intensity of retinal fluorophores. It mainly derives its signal from lipofuscin at the level of the retinal pigment epithelium. Fundus autofluorescence, however, can not only be characterized by the spatial distribution of the fluorescence intensity or emission spectrum, but also by a characteristic fluorescence lifetime function...

Purpose: To investigate structural correlates corresponding to the appearance of increased fundus autofluorescence (FAF) in the perilesional area of geographic atrophy (GA) secondary to age-related macular degeneration. Methods: Serial FAF images of 181 eyes with GA of 134 patients participating in the Directional Spread in Geographic Atrophy study (NCT02051998) were screened for increased FAF spots that had developed during the review period. Thickness and reflectivity of the retinal pigment epithelium (RPE)-basal lamina complex, as well as the integrity of the external limiting membrane (ELM) and the ellipsoid zone (EZ), respectively, in corresponding optical coherence tomography (OCT) scans were compared between the time points before and after the appearance of increased FAF...

PURPOSE: To describe evolution and progression of a lamellar macular hole (LMH) with "lamellar hole-associated epiretinal proliferation (LHEP)" using spectral-domain optical coherence tomography and fundus autofluorescence. METHODS: Observational case report. RESULTS: We report on a 63-year-old male patient demonstrating a complete history of LMH development with LHEP occurring during a follow-up period of 8 years. Presenting with a normal foveal contour and attached posterior vitreous at first visit, an LMH developed shortly after incomplete posterior vitreous detachment with vitreopapillary adhesion...

Geographic atrophy is an advanced form of age-related macular degeneration (AMD) and a leading cause of vision loss for which there are no approved treatments. Genetic studies in AMD patients have implicated dysregulation of the alternative complement pathway in the pathogenesis of geographic atrophy. Lampalizumab is a potential therapeutic that targets complement factor D, a pivotal activator of the alternative complement pathway. The MAHALO phase 2 clinical trial was a multicenter, randomized, controlled study that evaluated lampalizumab administered by intravitreal injection monthly (n = 42) and every other month (n = 41) versus sham control (n = 40) in patients with geographic atrophy secondary to AMD...

PURPOSE: Multimodal imaging has not been documented for CABP4-related retinopathy. In this study, we describe optical coherence tomography (OCT) and fundus autofluorescence findings for five genetically confirmed cases. METHODS: Retrospective case series. RESULTS: Four patients with the previously described homozygous Saudi CABP4 founder mutation c.81_82insA (p.Pro28ThrfsX44) and one patient with the homozygous mutation c.1A>G (p.Met1?) in CABP4 were examined...

PURPOSE: To examine the association between subretinal drusenoid deposits (SDDs) identified by multimodal retinal imaging and visual function in older eyes with normal macular health or in the earliest phases of age-related macular degeneration (AMD). METHODS: Age-related macular degeneration status for each eye was defined according to the Age-Related Eye Disease Study (AREDS) 9-step classification system (normal = Step 1, early AMD = Steps 2-4) based on color fundus photographs...

PURPOSE: To describe an atypical case of chronic central serous chorioretinopathy (CSCR). METHODS: A 58-year-old man with longstanding, bilateral visual impairment was self-referred for a second opinion. RESULTS: Findings by direct ophthalmoscopy, optical coherence tomography, fluorescein angiography, and fundus autofluorescence (FAF) were suggestive of atypical, chronic CSCR. Treatment with oral anti-mineralocorticoids resulted in moderate improvement, and photodynamic therapy (PDT) had minimal effect...
