Purpose: To review long time treatment results in patients with small or medium sized choroidal melanoma who underwent surgical tumor endoresection as a primary treatment when plaque radiotherapy was unable and patients declined enucleation. Materials and methods: Patients were evaluated for best corrected visual acuity (BCVA), and underwent biomicroscopy, indirect ophthalmoscopy, retinography and ultrasound as well as the usual systemic workup. Study inclusion required the absence of scleral invasion or metastasis and an anterior margin not exceeding the pars plana or the ciliary body...

The advent of magnetic resonance imaging (MRI) enables noninvasive measurement of cerebrospinal fluid (CSF) motion, and new information about CSF motion has now been acquired. The driving force of the CSF has long been thought to be choroid plexus (CP) pulsation, but to investigate whether this phenomenon actually occurs, CSF motion was observed in the ventricular system and subarachnoid space using MRI. Eleven healthy volunteers, ranging in age from 23 to 58 years, participated in this study. The MRI sequences used were four-dimensional phase-contrast (4D-PC) and time-spatial labeling inversion pulse (t-SLIP)...

PURPOSE: The feasibility of steady-state sequences for (17)O imaging was evaluated based on a kinetic analysis of the brain parenchyma and cerebrospinal fluid (CSF). MATERIALS AND METHODS: The institutional review board approved this prospective study with written informed consent. Dynamic 2D or 3D steady-state sequences were performed in five and nine participants, respectively, with different parameters using a 3T scanner. During two consecutive dynamic scans, saline was intravenously administered for control purposes in the first scan, and 20% (17)O-labeled water (1 mL/Kg) was administered in the second scan...

Yousif Subhi, Torben L Sørensen
Purpose: To describe a case of Valsalva-related subretinal hemorrhage as a presenting symptom of polypoidal choroidal vasculopathy (PCV). The patient refrained from treatment against our best advice, and thus this is also a rare case of the natural course of an untreated PCV. Methods: Case report. Results: A 66-year-old female with a respiratory infection coughed intensely until exhaustion, after which she developed visual symptoms on the right eye...

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: Retinopathy of prematurity (ROP) is one of the major problems of surviving premature infants with several ophthalmic morbidities such as increased risk of refractive errors, strabismus, and cortical visual impairment. Use of propranolol hydrochloride (PH) for the prevention of ROP is a new promising treatment modality. However, long-term effects are still to be defined. In our study, we aimed to investigate the short-term refractive effects of PH used for ROP prophylaxis in very preterm newborns...

Purpose: We hypothesized that the elastic nature of the choroid leads to tissue contraction following a full-thickness, sharp incision. Furthermore, we sought to quantify, measure, and compare tissue contraction in ex vivo porcine globes and human globes of various ages using predetermined variables. Method: A full-thickness, ex vivo choroidal incision was performed in either pig (n = 97) or human (n = 30) specimens. Variables included trephine diameter (1.5, 2...

Purpose: To use a novel optical coherence tomography angiography (OCTA) algorithm termed variable interscan time analysis (VISTA) to evaluate relative blood flow speeds in polypoidal choroidal vasculopathy (PCV). Methods: Prospective cross-sectional study enrolling patients with confirmed diagnosis of PCV. OCTA of the retina and choroid was obtained with a prototype swept-source OCT system. The acquired OCT volumes were centered on the branching vascular network (BVN) and polyps as determined by indocyanine-green angiography (ICGA)...

This report demonstrates the blood flow pattern in a case of choroidal hemangioma (CH) using swept-source-optical coherence tomography angiography (SS-OCTA). Fluorescein angiography, SS-OCT, and SS-OCTA images of a patient with CH were obtained using a standard protocol. The internal vascular pattern of the tumor was identified on both OCT and OCTA. Dark areas were identified in the CH. These were interspersed between areas of visible blood flow, as imaged on SS-OCTA. Peripheral vascular arcades were also identified within the tumor...

PURPOSE: To evaluate the effect of extraretinal proliferative vitreoretinopathy (PVR) on retinal shortening in eyes with rhegmatogenous retinal detachment (RD) using ultrasound (USG) and objectively prove the presence of intraretinal PVR (iPVR). METHODS: This is a double-masked pilot prospective controlled case series. Patients with total RD planned for vitreoretinal surgery were included in the study. USG was used to determine retinal-to-choroidal length ratios (RCRs) in all the quadrants...

Purpose: To study the distribution of choroidal thickness (CT) in and outside of the vascular arcade, as well as at the fovea in healthy eyes using spectral-domain optical coherence tomography (OCT). Methods: Seventy healthy eyes were examined with OCT to obtain nine horizontal lines in and outside of the vascular arcade. Nine points including the central point of the line were chosen in 0.5-mm intervals to calculate CT. CT was measured at a total of 81 points in each patient to construct a map of CT distribution...

BACKGROUND: We aimed to determine the physiological symmetry, with spectral-domain optical coherence tomography, of choroidal measurements in a healthy population in all the areas defined in the Early Treatment Diabetic Retinopathy Study (ETDRS). METHODS: One hundred and fifty-four eyes of 77 healthy young adults between the ages of 19 and 32 years were enrolled. Differences in choroidal thickness (CT) and volume (CV) between the left and right eyes were calculated...

To assess predictors of treatment response in neovascular age-related macular degeneration (AMD) in an attempt to develop a patient-centric treatment algorithm. We conducted a systematic search using PubMed, EMBASE and Web of Science for prognostic indicators/predictive factors with the key words: 'age related macular degeneration', 'neovascular AMD', 'choroidal neovascular membrane (CNV)', 'anti-vascular endothelial growth factor (anti-VEGF)', 'aflibercept', 'ranibizumab', 'bevacizumab', 'randomized clinical trials', 'post-hoc', 'prognostic', 'predictive', 'response' 'injection frequency, 'treat and extend (TAE), 'pro re nata (PRN)', 'bi-monthly' and 'quarterly'...

Optical coherence tomography angiography (OCT-A) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in choroidal nevi is scarce. We report the OCT-A findings associated with two different variants. Subject one had decreased vascular flow signal in the choroidal, choriocapillaris, deep retinal, and superficial retinal layers. Subject two had decreased vascular flow signal in the choroidal, choriocapillaris, and deep retinal layers with a normal vascular flow signal in the superficial retinal layer...
