Ocular cytology specimens are relatively uncommon, adding to the difficulty of their evaluation by cytopathologists. While melanomas account for a majority of primary intraocular pigmented lesions, other diagnostic considerations must be included in the differential. This brief report highlights a case of a pigmented ocular lesion in a 24-year-old man and key morphologic, immunohistochemical, and clinical differences between melanoma, melanocytoma, choroidal nevus, and retinal pigment epithelium (RPE) adenoma...

Koung Li Kim, Wonhee Suh
Purpose: Vascular endothelial growth factor (VEGF) signaling via VEGF receptor 2 (VEGFR2) plays a crucial role in pathologic ocular neovascularization. In this study, we investigated the antiangiogenic effect of apatinib, a pharmacologic inhibitor of VEGFR2 tyrosine kinase, against oxygen-induced retinopathy (OIR) and laser-induced choroidal neovascularization (CNV) in mice. Methods: Western blotting and in vitro angiogenesis assays were performed using human retinal microvascular endothelial cells (HRMECs)...

Purpose: The prevailing view is that the human retina is supplied by the central retinal artery (CRA), the short posterior ciliary arteries (SPCAs) support the choroid, and both the CRA and the SPCAs are so-called "end artery" systems. In this study, we investigate whether vascular connections among the retina, choroid, and the optic nerve head (ONH) exist, using selective cannulation and microperfusion-labeling techniques. Methods: The CRA and/or one or more of the SPCAs were selected for cannulation in 18 human donor eyes...

Purpose: Age-related macular degeneration (AMD) is a progressive disease with multifactorial etiology. There is a need to identify clinical features that are harbingers of advanced disease. We evaluated morphologic features of the retina and choroid on optical coherence tomography (OCT) to determine if they predict progression to advanced disease. Methods: Progressors transitioned from early or intermediate AMD to advanced disease (n = 40 eyes), and were matched on baseline AMD grade and follow-up interval to nonprogressors who did not develop advanced AMD (n = 40 eyes)...

The retinal and choroidal blood flow dynamics may provide insight into the pathophysiology and sequelae of various ocular diseases, such as glaucoma, diabetic retinopathy, age-related macular degeneration (AMD) and other ocular inflammatory conditions. It may also help to monitor the therapeutic responses in the eye. The proper labeling of the blood cells, coupled with live-cell imaging of the labeled cells, allows for the investigation of the flow dynamics in the retinal and choroidal circulation. Here, we describe the standardized protocols of 1...

PURPOSE: Age-related macular degeneration (AMD) is a frequent, complex disorder in elderly of European ancestry. Risk profiles and treatment options have changed considerably over the years, which may have affected disease prevalence and outcome. We determined the prevalence of early and late AMD in Europe from 1990 to 2013 using the European Eye Epidemiology (E3) consortium, and made projections for the future. DESIGN: Meta-analysis of prevalence data. PARTICIPANTS: A total of 42 080 individuals 40 years of age and older participating in 14 population-based cohorts from 10 countries in Europe...

BACKGROUND: cerebrospinal fluid (CSF) is sequestered from blood by the blood-brain barrier and directly communicates with brain parenchymal interstitial fluid, leading to contain specific biomarkers of neurological diseases. SCOPE OF REVIEW: CSF contains glycan isoforms of transferrin (Tf): one appears to be derived from the brain and the other from blood. MAJOR CONCLUSIONS: CSF contains two glycan-isoforms; brain-type Tf and serum-type Tf...

PURPOSE: Gyrate atrophy of the choroid and retina (GACR) is a rare chorioretinal dystrophy characterized by a deficiency of the enzyme ornithine aminotransferase, inherited in an autosomal recessive pattern. CASE REPORT: We report a case of a 17-year-old girl with GACR, for whom the level of serum ornithine had been reduced by an arginine-restricted diet. The patient was responsive to an association of topical nonsteroidal anti-inflammatory drugs (NSAIDs) and a carbonic anhydrase inhibitor (CAI) to reduce cystoid macular edema (CME)...

PurposeThe purpose of this study is to investigate the factors associated with reactivation of the lesion during the first year in patients with polypoidal choroidal vasculopathy (PCV) treated with intravitreal ranibizumab.Patients and methodsThis retrospective observational study included 84 eyes diagnosed with PCV and treated with 3-monthly ranibizumab injections. Only those patients who exhibited complete resolution of fluid after initial treatment and were followed up at least 12 months were included. The baseline characteristics of the patients, including their age and sex, location of the polyps, greatest linear dimensions of the lesions, largest polyp diameter, choroidal vascular hyperpermeability, submacular hemorrhages ≥1 disc area in size, presence of grape-like polyp clusters, central foveal thickness, and best-corrected visual acuity were compared between patients with and without reactivation of the lesion...

INTRODUCTION: The newly developed optical coherence tomography angiography (OCT-A) has provided new means to depict the vascular plexus in neovascular age-related macular degeneration (nAMD). If these images are to be used as a basis for therapeutic decisions, it is of vital importance to classify choroidal neovascularization (CNV) as either classical or occult. This study aimed at comparing the findings in OCT-A imaging of CNV with the traditional multimodal imaging through fluorescein angiography (FLA) and indocyanine green angiography (ICGA)...

PURPOSE: Kynurenine aminotransferases (KATs) catalyze the synthesis of kynurenic acid (KYNA), a compound of significant biological activity. The aim of this study is to investigate the presence and distribution of KAT immunoreactivity in the healthy human cornea. METHODS: Data on gene expression in human eye structures were extracted from public microarray experiments using Genevestigator software. Immunohistochemistry was conducted using polyclonal antibodies against KAT I, II, and III on sections of eight enucleated eyes from patients with choroidal melanoma...

A 54-year-old woman visited Gangnam Severance Hospital for left side flank pain. She had a history of total removal of malignant melanoma on the left eye ball 20 years prior. No evaluation had been performed since then. A paravertebral mass at thoracic ninth level (T9) was discovered on spinal magnetic resonance imaging, and pathology confirmed malignant melanoma. Following positron emission tomography-computed tomography, no other metastasis was discovered. After removal of the paravertebral mass, palliative chemotherapy (dacabarzine + tamoxifene) was administered in 3 cycles over 2 months...

PURPOSE: To evaluate the efficacy and safety of ranibizumab 0.5 mg in adult patients with choroidal neovascularization because of an uncommon cause enrolled in the 12-month MINERVA study. METHODS: In this Phase III, double-masked study, adult (≥18 years) patients (N = 178) were randomized 2:1 to receive either ranibizumab (n = 119) or sham (n = 59) at baseline and, if needed, at Month 1 and open-label individualized ranibizumab from Month 2. Best-corrected visual acuity change from baseline to Month 2 (primary endpoint) and Month 12, treatment exposure, and safety over 12 months were reported...

Collie eye anomaly (CEA) encompasses a spectrum of different ophthalmic phenotypes from clinically inconsequential choroidal hypoplasia to blindness from coloboma of the optic nerve head (ONH). A previous study found a 7.8-kb deletion in intron 4 of the NHEJ1 gene to be associated with CEA. A genetic test based on this association is recommended for many breeds, including the Nova Scotia Duck Tolling Retriever (NSDTR). Collection of ONH coloboma-affected NSDTR showed lack of concordance of the NHEJ1 intronic deletion with ONH coloboma...

PURPOSE: To test the significance of diurnal changes in choroidal, Haller's and Sattler's layer thickness in healthy subjects using spatial analysis of three-dimensional (3D) 1060-nm optical coherence tomography (OCT) scans. METHODS: Automatically generated choroidal, Haller's and Sattler's layer thickness maps were statistically analyzed for 19 healthy subjects at two time points (8 a.m. and 6 p.m.) that represent the currently proposed ChT peak and nadir. All subjects were imaged by high-speed 1060-nm OCT over a 36° × 36° field of view...
