Idiopathic multifocal choroiditis (MFC) and/or punctate inner choroidopathy (PIC) describe a chronic progressive bilateral inflammatory chorioretinopathy that predominantly affect healthy myopic white women with no known associated systemic or ocular diseases. The principal sites of involvement are the retinal pigment epithelium (RPE) and outer retinal spaces; the choroid is not affected during the active phase of the disease. Idiopathic MFC with atrophy is a recently described variant. Although there is no generally accepted standard treatment, anti-inflammatory and anti-VEGF (vascular endothelial growth factor) agents are necessary in the acute stage to control the inflammation and choroidal neovascularization (CNV)...

PURPOSE: To report the pathogenic factors that account for cystoid macular edema and cystoid macular degeneration in chronic central serous chorioretinopathy (CSC). METHODS: The clinical course and multimodal imaging findings, including fundus color photography, fundus autofluorescence, spectral-domain optical coherence tomography, and fluorescein angiography, of one eye with cystoid macular edema due to chronic CSC was documented. RESULTS: A 44-year old woman with a history of chronic CSC presented with progressive visual decline in the right eye...

PURPOSE: To evaluate the spectrum of macular chorioretinal lesions occurring in idiopathic multifocal choroiditis using optical coherence tomography angiography (OCTA) to evaluate those showing neovascular flow. METHODS: This was a descriptive, retrospective study of 18 eyes of 14 patients with multifocal choroiditis. Macular lesions were characterized as subretinal pigment epithelium, subretinal, or mixed and evaluated during active and presumed inactive states of multifocal choroiditis...

Purpose: Drusenoid pigment epithelial detachments (PEDs) are a defined path to atrophy in age-related macular degeneration (AMD). We analyzed the relationships between retinal pigment epithelium (RPE) and drusen volume changes during the PED lifecycle, using spectral-domain optical coherence tomography (SD-OCT). Methods: Twenty-one cases of drusenoid PED tracked using SD-OCT through periods of growth and collapse were evaluated. Volumetric calculations and piece-wise linear regression analysis were used to determine the breakpoint between growth and collapse...

PURPOSE: To evaluate multimodal imaging including volume-rendered angiographic and structural optical coherence tomography of macular telangiectasia Type 2 (MacTel2) for right-angle vein complexes, macular cavitations, and signs of deeper retinal vascular invasion. METHODS: Retrospective review of imaging performed in a community-based retinal referral center. The eyes were scanned using optical coherence tomography using split-spectrum amplitude-decorrelation techniques to derive flow information...

PURPOSE: To study the cross-sectional and en face optical coherence tomography angiography (OCTA) findings in Type 3 neovascularization (NV). METHODS: Optical coherence tomography angiography imaging of 27 eyes of 23 patients with Type 3 NV was analyzed with 9 eyes having consecutive follow-up OCTA studies. RESULTS: Type 3 NV appeared as a linear high-flow structure on cross-sectional OCTA corresponding to a high-flow tuft of vessels seen on en face OCTA...

PURPOSE: To report a case of unilateral stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) in a young male showing structural changes induced by a Valsalva maneuver. METHODS: Case report of a 26-year-old oboist with SNIFR, including multimodal imaging. Eye-tracked spectral-domain optical coherence tomography (SD-OCT) was used to compare the retinal architecture at rest and during a Valsalva maneuver. RESULTS: Spectral-domain optical coherence tomography showed macular and peripapillary retinoschisis with no signs of pathologic myopia, optic pit, or vitreoretinal traction...

PURPOSE: To quantify the temporal properties of the acquired vitelliform lesion (AVL) lifecycle, define the clinical characteristics of choroidal neovascularization (NV) in this setting and determine the predictors of long-term visual outcomes. DESIGN: Retrospective cohort study METHODS: Clinical and imaging data from 199 eyes of 124 consecutive patients with AVLs associated with age-related macular degeneration (AMD) and adult-onset foveomacular vitelliform dystrophy (AOFVD) were analyzed...

PURPOSE: To describe and compare the clinical and imaging characteristics of pigment epithelial detachments (PEDs) in age-related macular degeneration (AMD), polypoidal choroidal vasculopathy (PCV) and central serous chorioretinopathy (CSC) as seen in a clinical setting of a tertiary retinal practice. DESIGN: A perspective supported by clinical and imaging characteristics of a consecutive, cohort of patients with strictly defined PEDs. RESULTS: 174 eyes of 113 patients with PEDs were studied with comprehensive clinical retinal examination and multi-modal imaging; PEDs were differentiated into non-vascularized and vascularized forms with 3 main underlying etiologies: AMD (76%), PCV (9%) and CSC (3%)...

PURPOSE: To determine if the area of the foveal avascular zone (FAZ) is correlated with visual acuity (VA) in diabetic retinopathy (DR) and retinal vein occlusion (RVO). DESIGN: Cross-sectional study. PARTICIPANTS: Ninety-five eyes of 66 subjects with DR (65 eyes), branch retinal vein occlusion (19 eyes), and central retinal vein occlusion (11 eyes). METHODS: Structural optical coherence tomography (OCT; Spectralis, Heidelberg Engineering) and OCT angiography (OCTA; Avanti, Optovue RTVue XR) data from a single visit were analyzed...

PURPOSE: To describe two patients who showed full-thickness macular holes (FTMH) combined with pigment epithelial detachments (PED) and had contrasting outcomes to treatment. METHODS: A retrospective report of two cases. RESULTS: Case 1 was treated with intravitreal antivascular endothelial growth factor and photodynamic therapy, and the PED flattened. Subsequently, a vitrectomy was performed and the FTMH closed. Her visual acuity improved from 20/200 to 20/25...

METHODS: A 52-year-old woman underwent multimodal imaging, including color fundus photography and spectral-domain optical coherence tomography, to confirm the diagnosis. RESULTS: The ophthalmic examination and imaging confirmed the findings of Purtscher retinopathy with significant inner retinal thickening on spectral-domain optical coherence tomography...

PURPOSE: The range of subretinal hyperreflective material (SHRM) seen in macular disease includes type 2 macular neovascularization, fibrosis, exudation, vitelliform material, and hemorrhage. The prognostic significance of SHRM has been evaluated retrospectively in clinical trials, but discriminating SHRM subtypes traditionally requires multiple imaging modalities. The purpose of this study is to describe optical coherence tomography angiography (OCTA) flow characteristics and artifacts that might help to distinguish SHRM subtypes...

BACKGROUND AND OBJECTIVE: To assess the outcomes of patients with macular telangiectasia type 2 (MacTel 2) in response to lutein (L), meso-zeaxanthin (M), and zeaxanthin (Z) supplements (LMZ3). PATIENTS AND METHODS: Thirteen patients diagnosed with MacTel 2 were started on lutein 10 mg, meso-zeaxanthin 10 mg, and zeaxanthin 2 mg and were followed-up for a mean period of 15.7 months ± 4.85 months. RESULTS: Visual acuity improved in three patients (13%), and there was a reduction in the percentage of patients who had worsening vision (25% to 4%; P < ...

PURPOSE: To report a case of full-thickness macular hole in a patient with X-linked retinoschisis and the outcome after surgical repair. METHODS: A 15-year-old boy with a history of X-linked retinoschisis presented to his ophthalmologist for routine follow-up and was found to have a Stage-3 macular hole in his left eye. His vision was 20/200. The patient underwent pars plana vitrectomy and internal limiting membrane peeling, and he received long-acting gas. Color fundus photography and spectral domain optical coherence tomography (Cirrus; Carl Zeiss Meditech Inc, Dublin, CA) recorded images at office visits, before and after surgical repair...
