PURPOSE: To determine whether improvements in microperimetry testing are associated with anatomic resolution after ocriplasmin treatment in patients with symptomatic vitreomacular adhesion (VMA)/vitreomacular traction and relatively preserved baseline best-corrected visual acuity (BCVA). METHODS: Patients with vitreomacular traction received a single 125-μg intravitreal ocriplasmin injection and were followed longitudinally for 6 months with optical coherence tomography, BCVA testing, and microperimetry...

PURPOSE: To describe the utility of microperimetry testing in the diagnosis of a bilateral occipital stroke. METHODS: Retrospective case report. RESULTS: A 57-year-old male with hypertension presented with complaints of bilateral blurred central vision and bilateral hypertensive retinopathy with cotton-wool spots. Automated perimetry demonstrated a central scotoma in both eyes that did not respect the vertical midline; however, microperimetry testing revealed a bilateral homonymous hemianopia that suggested cerebrovascular disease which was subsequently confirmed with magnetic resonance imaging...

PURPOSE: To report visualization of a case of retinal deep capillary plexus ischemia with antiphospholipid syndrome. METHODS: A 53-year-old woman was referred with a 1-week history of sudden onset of decreased vision in the right eye. Her symptoms were evaluated by clinical examination, infrared reflectance, fundus autofluorescence, fluorescein angiography, spectral-domain optical coherence tomography, microperimetry, and multifocal electroretinography. RESULTS: The patient's visual acuity on presentation was 0...

BACKGROUND: MAIA microperimetry assesses macular sensitivity to projected point light sources and maps eye movements to assess fixation stability. While microperimetry is gaining prominence as an assessment tool in clinical and research settings, there is no consensus on whether it should be performed before or after pupil dilation. No studies to date have examined the effect of pupil dilation on results. The aim of this project was to elucidate the effect of pupil dilation on microperimetry outcomes...

PURPOSE: To investigate the parafoveal perfusion status of the superficial and deep capillary layer in eyes with resolved branch retinal vein occlusion, and to study its effects on retinal sensitivity. METHODS: In 27 enrolled eyes (27 patients) with resolved branch retinal vein occlusion, superficial and deep capillaries in the macular area (3- × 3-mm, centered on the fovea) were examined with optical coherence tomography angiography. Retinal sensitivity was examined with fundus-monitored microperimetry...

PurposeThe purpose of the study was to study the effect of an organic light-emitting diode sleep mask on daytime alertness, wellbeing, and retinal structure/function in healthy volunteers and in diabetic macular oedema (DMO).Patients and methodsHealthy volunteers in two groups, 18-30 yrs (A), 50-70 yrs (B) and people with DMO (C) wore masks (504 nm wavelength; 80 cd/m(2) luminance; ≤8 h) nightly for 3 months followed by a 1-month recovery period. Changes from baseline were measured for (means): psychomotor vigilance task (PVT) (number of lapses (NL), response time (RT)), sleep, depression, psychological wellbeing (PW), visual acuity, contrast sensitivity, colour, electrophysiology, microperimetry, and retinal thickness on OCT...

PURPOSE: To present en face optical coherence tomography (OCT) images generated by graph-search theory algorithm-based custom software and examine correlation with other imaging modalities. METHODS: En face OCT images derived from high density OCT volumetric scans of 3 healthy subjects and 4 patients using a custom algorithm (graph-search theory) and commercial software (Heidelberg Eye Explorer software (Heidelberg Engineering)) were compared and correlated with near infrared reflectance, fundus autofluorescence, adaptive optics flood-illumination ophthalmoscopy (AO-FIO) and microperimetry...

BACKGROUND: Previous studies of neuromyelitis optica spectrum disorder (NMOSD) using spectral domain optical coherence tomography (SD-OCT) showed that the outer nuclear layer (ONL) in eyes without a history of optic neuritis (ON) was thinner than that of healthy controls. It remains unclear whether the ONL thinning is caused by a direct attack on the retina by an autoantibody or a retrograde degeneration. OBJECTIVE: To determine the mechanisms involved in the retinal damage in eyes with NMOSD without ON...

AIM: To improve the approach to pathogenetic treatment of diabetic retinopathy (DR) through early diagnosis and a new method for predicting disease progression. MATERIAL AND METHODS: The study enrolled 330 type 2 diabetes patients with DR (660 eyes), of whom women constituted 64.6%, men - 35.4%. The mean patient age was 62.3±2.3 years. Three groups were formed: the controls - 30 healthy volunteers (60 eyes) and 30 type 2 diabetes patients without ocular involvement (DR 0, 60 eyes); group 1 - 30 type 2 diabetes patients with DR I but no diabetic macular edema (DR I without DME, 60 eyes) that were treated with calcium dobesilate; group 2 - 240 type 2 diabetes patients, who had diabetic retinopathy of different stages (DR I, II, or III with DME, 480 eyes) and received laser retinal photocoagulation (LRP)...

PURPOSE: To assess the epi- and intra-retinal morphology changes of the tangential tractions following vitreoretinal surgery for epiretinal membranes and to investigate the correlation between the depth of retinal changes and functional macular sensitivity (MS). METHODS: This is a prospective cross-sectional interventional study, in which 73 eyes of 73 patients with diagnosis of idiopathic epiretinal membrane (iERM) were evaluated. All patients received complete ophthalmic evaluation, including axial and en-face scanning spectral domain-optical coherence tomography (SD-OCT) analysis and microperimetry...

Purpose: To assess the feasibility of macular integrity assessment (MAIA) microperimetry (MP) in children. Also to establish representative outcome measures (differential light sensitivity, fixation stability, test-retest reliability) for children without visual impairment. Methods: Thirty-three adults and 33 children (9-12 years) were asked to perform three monocular MAIA examinations within a single session (dominant eye only). Results: Children exhibited poorer test-retest reliability than adults for measures of both mean sensitivity (95% coefficient of repeatability [CoR95] = 2...

Occult macular dystrophy is an inherited macular dystrophy characterized by a progressive decline of bilateral visual acuity with normal fundus appearance, fluorescein angiogram and full-field electroretinogram. This case report presents a 20-year-old female patient with bilateral progressive decline of visual acuity for six years. Her visual acuity was 3-4/10 in both eyes. Anterior segment and fundus examination, fluorescein angiogram and full-field electroretinogram were normal. She could read all Ishihara pseudoisochromatic plates...

Microperimetry, also referred to as fundus perimetry or fundus-driven perimetry, enables simultaneous acquisition of visual sensitivity and eye movement data. We present sensitivity data collected from 60 participants with normal vision using gaze-contingent perimetry. A custom designed spatially dense test grid was used to collect data across the visual field within 13° of fixation. These data are supplemental to a study in which we demonstrated a spatial interpolation method that facilitates comparison of acquired data from any set of spatial locations to normative data and thus screening of individuals with both normal and non-foveal fixation (Denniss and Astle, 2016) [1]...

BACKGROUND: Intrachoroidal cavitation (ICC) in the temporal peripapillary area is a relatively frequent finding in high myopia. However, ICC associated with a full thickness retinal defect rarely observed. We report an unusual case of ICC combined with a full thickness retinal defect in the papillo-macular bundle, in which the spatially corresponding visual field sensitivity was preserved. CASE PRESENTATION: A high myopic and pseudophakic left eye of a 79-year-old Japanese woman was evaluated with swept source optical coherence tomography (SS-OCT) and Humphrey 30-2 visual field testing for moderate glaucoma...

PURPOSE: To evaluate changes of specific retinal imaging biomarkers [intraretinal hyper-reflective retinal spots: HRS ; subfoveal neuroretinal detachment: SND; and increased foveal autofluorescence: IFAF after intravitreal steroid or anti-vascular endothelial growth factor treatment in diabetic macular oedema (DME)] as possible indicators of retinal inflammatory condition. METHODS: Retrospective analysis of images and clinical charts of 49 eyes (49 patients) with DME treated with intravitreal dexamethasone (dexamethasone, 23 eyes) or intravitreal ranibizumab (ranibizumab, 26 eyes)...
