Purpose: To determine the clinical significance of retinal pigment epithelium (RPE) undulations in the acute stage of Vogt-Koyanagi-Harada disease.
Methods: Retinal pigment epithelium undulations were detected and classified into 3 grades: Grade 1, slight; Grade 2, moderate; and Grade 3, severe undulations, in the enhanced depth imaging optical coherence tomographic images. The relationship between the clinical characteristics and the presence of RPE undulations was investigated.
Purpose: To examine predictive factors for visual acuity in highly myopic eyes.
Methods: Consecutive patients with high myopia (≥6 diopters [D]) with no other pathology such as lacquer cracks in the fovea, choroidal neovascularization, or myopic macular schisis, were evaluated. The study was performed in 2 retina centers, one in the United States and the other in Japan.
Purpose: To investigate the fundus autofluorescence (FAF) abnormalities in central serous chorioretinopathy (CSC) and evaluate potential correlations with visual acuity.
Design: Retrospective, observational case series.
Participants: Four hundred seventy-five eyes of 238 patients with CSC.
Purpose: To evaluate the subfoveal choroidal thickness in Vogt-Koyanagi-Harada (VKH) disease using enhanced depth imaging optical coherence tomography.
Methods: Retrospective observational study. Subfoveal choroidal thickness was measured using enhanced depth imaging optical coherence tomography, in which the optical coherence tomography instrument was placed close enough to the eye to obtain an inverted image, which was averaged for 100 scans.
Purpose: To determine the intravitreal levels of vascular endothelial growth factor (VEGF) in eyes with anterior hyaloidal fibrovascular proliferation (AHFVP).
Methods: Three eyes of three patients who underwent vitrectomy for proliferative diabetic retinopathy (PDR) and subsequently developed an AHFVP (AHFVP group) were studied. We measured the level of VEGF in vitreous samples collected at the primary and following operations by enzyme-linked immunosorbent assay.
Purpose: To present the first findings in the set of monozygotic twins with polypoidal choroidopathy (PCV).
Methods: Sixty two-year old monozygotic twin sisters were studied. The concordances and discordances of the clinical features of the twins were determined.
Purpose: The purpose of this study was to investigate the fundus autofluorescence and optical coherence tomography findings in eyes with acute zonal occult outer retinopathy (AZOOR).
Methods: A retrospective observational case series of the fundus autofluorescence and spectral domain optical coherence tomography in a series of patients with AZOOR.
Results: There were 19 eyes of 11 patients (10 women), who had a mean age of 49.
Purpose: The purpose of this study was to characterize retinal manifestations of optic pit maculopathy using high-resolution optical coherence tomography.
Methods: Consecutive patients with optic pit maculopathy, diagnosed by their typical appearance by ophthalmoscopy, were imaged by color fundus photography and optical coherence tomography. The location and characteristics of any fluid within and under the retina were determined.
Purpose: To determine the prevalence and significance of subretinal drusenoid deposits (reticular pseudodrusen) among patients with age-related macular degeneration (AMD).
Design: A prospective study with a nested case-control study of consecutive patients with AMD seen in a referral retinal practice.
Participants: There were 153 patients with AMD, 131 of whom had > or =1 eye with late AMD, which was defined as either central geographic atrophy or choroidal neovascularization.
Purpose: To report a case of Vogt-Koyanagi-Harada (VKH) disease presenting mutton fat like subretinal precipitates.
Design: Observational case report.
Methods: A 52-year-old Japanese woman developed bilateral uvetis with serous retinal detachment and mutton fat like subretinal precipitates.
Purpose: The purpose of this study was to investigate the frequency of glaucoma and related conditions in patients with central serous chorioretinopathy (CSC), a condition associated with increased choroidal thickness.
Methods: A case-control study was conducted. Consecutive patients with CSC examined from January 1, 2006, through July 31, 2008, were compared with a sex- and age-matched control group from the same referral practice seen during the same period for the frequency of glaucoma and related conditions.
Purpose: The purpose of the study was to evaluate the choroidal thickness in patients with central serous chorioretinopathy, a disease attributed to increased choroidal vascular hyperpermeability.
Methods: Patients with central serous chorioretinopathy underwent enhanced depth imaging spectral-domain optical coherence tomography, which was obtained by positioning a spectral-domain optical coherence tomography device close enough to the eye to acquire an inverted image. Seven sections, each comprising 100 averaged scans, were obtained within a 5 degrees x 30 degrees rectangle to encompass the macula.
Purpose: To measure macular choroidal thickness (CT) in highly myopic eyes using enhanced depth imaging optical coherence tomography (OCT).
Design: Retrospective, observational case series.
Methods: Enhanced depth imaging OCT images were obtained in highly myopic eyes (> or =6 diopters [D]).
Background: We report a case of herpes simplex virus (HSV) epithelial keratitis that developed after a subtenon triamcinolone acetonide (TA) injection.
Method: A 78-year-old woman with a branch retinal vein occlusion and diffuse macular edema in her left eye received a subtenon injection of 20 mg of TA.
Results: Six days after the injection, the patient presented with a foreign body sensation, tearing, redness, and photophobia in the same eye.
Purpose: To report a case in which a macular hole (MH) associated with a ruptured retinal arteriolar aneurysm (RAM) closed without surgical intervention.
Patient And Results: A 65-year-old woman presented complaining of sudden visual loss due to vitreous hemorrhage in the left eye. Correctable visual acuity in the left eye was 2/100 at the initial visit.
Purpose: We describe four patients with idiopathic choroidal neovascularization (ICNV) who developed inflammatory chorioretinal diseases in the ipsilateral or contralateral eye.
Methods: The medical records of 58 eyes of 58 patients with an initial diagnosis of ICNV (age range, 19-49 years; mean, 34.9 years) were reviewed.
Unilateral cone dysfunction as a manifestation of acute zonal occult outer retinopathy.
Retin Cases Brief Rep
November 2014
Purpose: To report a patient with unilateral cone dysfunction (UCD) who later developed acute zonal occult outer retinopathy (AZOOR) in the contralateral eye.
Methods: A 19-year-old Japanese woman was referred complaining of decreased vision and photopsia of the left eye. Static perimetry, full-field electroretinography (ERG), and multifocal ERGs (mfERGs) were performed to evaluate her visual functions.
Purpose: To determine whether myopia is more prevalent in Japanese patients with idiopathic focal subretinal neovascularization (IFSN) than in normal control subjects.
Methods: Forty-seven eyes of 46 patients with an initial diagnosis of IFSN and 291 eyes of 291 controls were studied. Refractive errors were measured with an autorefractometer, and the spherical equivalent of the refractive error was used for the statistical analyses.
Purpose: To investigate how long indocyanine green (ICG) dye remains in the ocular fundus and how the remaining dye interferes with ICG angiographic findings after vitreoretinal surgery assisted by ICG.
Methods: Eight eyes with macular hole, three with epiretinal membrane, and one with an intraocular foreign body were included. Those patients underwent vitrectomy facilitated by an intraocular administration of ICG.
The recalling processes of associative memory proposed by Amari and Maginu are analyzed without any assumption on asymptotic distributions of noise using an integral representation of the sign function and by introducing extra variables. General procedures for calculating mean of direction cosine a(t) between a certain memory s(1) and the state x(t) at time t are developed and the exact formulas for E[a(t)] are obtained up to t = 3. It is shown explicitly that E[a(3)] involves non-Gaussian effects caused by some self-coherences.
