PURPOSE: To compare the diagnostic ability of optical coherence tomography angiography (OCTA) with indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV). METHODS: Retrospective review of 47 eyes with PCV imaged with ICGA and OCTA. For each eye, it was determined which imaging modality better delineated the PCV complex. The presence of a branching vascular network (BVN) and polyp(s) were noted. RESULTS: PCV was better visualized with ICGA in 21 eyes (44...

Sulpha drugs are widely employed in medicine for various diseases and disorders. During the last several decades, numerous papers had been published on supra ciliary and posterior choroidal effusion likely presenting as an idiosyncratic effect of these drugs especially of acetazolamide. In each publication, the effusion was associated with either an acute angle-closure glaucoma or transitory myopia or both of these as leading symptoms. In the current publication, authors report on two cases where the acetazolamide-induced choroidal effusion was an accidental finding without either a myopic shift in refraction or an acute elevation in intraocular pressure...

Songyi Seo, Wonhee Suh
Purpose: Vascular endothelial growth factor (VEGF) is a principal mediator of pathological ocular neovascularization, which is the leading cause of blindness in various ocular diseases. As Src, a non-receptor tyrosine kinase, has been implicated as one of the major signaling molecules in VEGF-mediated neovascularization, the present study aimed to investigate whether dasatinib, a potent Src kinase inhibitor, could suppress pathological ocular neovascularization in murine models of oxygen-induced retinopathy (OIR) and choroidal neovascularization (CNV)...

PURPOSE: To determine whether microvasculature dropout (MvD) in the parapapillary choroid is related to the presence of central visual field defects in primary open-angle glaucoma (POAG). DESIGN: Cross-sectional observational study. PARTICIPANTS: Thirty-two POAG patients with an initial parafoveal scotoma (IPFS) within a 10° radius in 1 hemifield and 42 POAG patients with an initial nasal step (INS) within the nasal periphery outside 10° of fixation in 1 hemifield...

An immunocompromised patient had positive blood cultures for Mycobacterium intracellulare and no identifiable organ seeding was started on treatment. One month later, the patient was clinically well with negative blood cultures but drug-induced myelotoxicity had developed. Ocular fundus examination at this time revealed bilateral choroidal granulomas which changed patient management.

PURPOSE: In this study (AMD2000), we aimed to determine the visual prognosis of Japanese patients with age-related macular degeneration (AMD). METHODS: This was a multicenter prospective observational cohort study. In total, 460 patients with AMD were recruited from April 2006 to March 2009 from 18 clinical trial sites in Japan. They were followed up for 5 years, as they continued to receive medical treatment. RESULTS: Of the 409 study eyes followed up for at least 1 year, 243 eyes (59...

PURPOSE: To investigate fundus abnormalities in Vogt-Koyanagi-Harada (VKH) disease by a noninvasive tool, multispectral imaging (MSI). METHODS: A total of 77 patients with VKH and 163 healthy controls were enrolled between January and April 2015. The MSI findings were evaluated in combination with fundus fluorescein angiography (FFA), optical coherent tomography (OCT) and fundus photography (FP). Additionally, we compared extent of exposure of choroidal blood vessels between patients with VKH and healthy controls to evaluate retinal transmission function...

BACKGROUND/PURPOSE: To report a case of cuticular drusen in an indigenous Australian. METHODS: A 37-year-old indigenous (aboriginal) Australian woman from a remote Western Australian town presented with a 2-month history of vision loss. Clinical history, examination, and multimodal retinal imaging data from spectral domain optical coherence tomography, fundus autofluorescence, fluorescein angiography, and indocyanine green angiography were analyzed. RESULTS: Multimodal imaging confirmed cuticular drusen complicated by a right choroidal neovascularization with pigment epithelial detachment and a left foveal vitelliform lesion...

BACKGROUND: The retina is an uncommon site for metastases, in particular from solid tumors. Some authors have reported a recent increase in the incidence of metastases in infrequent sites, such as brain or bone, probably due to the expanded treatment options and the resulting improved survival. Choroidal metastasis is the most common type of intraocular malignancy. The most common primary sites associated with choroidal metastasis are breast cancer in women and lung cancer in men. Treatment options are limited, but they must be discussed and adapted to the patient profile...

The choroid is the most common site for intraocular metastatic disease. Photodynamic therapy (PDT) can effectively destroy malignant tissue and induce anti-tumor activity. Recent publications support its use as an effective therapy for the treatment of choroidal metastases, especially in the subfoveal region, resulting in subsequent vision preservation or improvement. Here, we introduce a case of choroidal metastasis, secondary to primary lung cancer. The progression of choroidal metastasis after PDT was followed up using spectral domain optical coherence tomography with point-to-point follow-up...

PURPOSE: To describe the qualitative and quantitative changes in choroidal neovascularization (CNV) flow pattern after anti-vascular endothelial growth factor therapy, by optical coherence tomography angiography (OCTA). METHODS: Consecutive patients with neovascular age-related macular degeneration underwent multimodal imaging, including OCTA at initial examination and at last visit. High-flow networks in the choriocapillaris segmentation of OCTA were qualitatively and quantitatively analyzed at baseline and at follow-up, to characterize vascular flow changes after anti-vascular endothelial growth factor treatment and to correlate these changes with final exudation signs on spectral domain optical coherence tomography...

Retinal hemorrhages (RH) are among injuries sustained by a large number of shaken baby syndrome victims, but also by a small proportion of road accident victims. In order to have a better understanding of the underlying of RH mechanisms, we aimed to develop a complete human eye and orbit finite element model. Five occipital head impacts, at different heights and on different surfaces, and three shaking experiments were conducted with a 6-week-old dummy (Q0 dummy). This allowed obtaining a precise description of the motion in those two specific situations, which was then used as input for the eye model simulation...

REVIEW
Katarzyna Konieczka, Carl Erb
Flammer syndrome (FS) is a prevalent and mostly benign condition. Subjects with FS seem to have a good life expectancy. Nevertheless, FS subjects are at increased risk for certain diseases, mainly when they are challenged by psychological stress or other stimuli such as coldness. FS is related to ocular diseases, such as normal-tension glaucoma, retinitis pigmentosa, central serous chorioretinopathy, optic nerve compartment syndrome, Leber's hereditary optic neuropathy, arterial or venous occlusions in the retina, and choroid and optic nerve head, despite the absence of classical vascular risk factors...
