Multidimensional en-face OCT imaging of the retina. [PDF]

open access: yes, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...

Holographic laser Doppler ophthalmoscopy [PDF]

open access: yesOptics Letters, 2010
We report laser Doppler ophthalmoscopic fundus imaging in the rat eye with near-IR heterodyne holography. Sequential sampling of the beat of the reflected radiation against a frequency-shifted optical local oscillator is made onto an array detector. Wide-field maps of fluctuation spectra in the 10 Hz to 25 kHz band exhibit angiographic contrasts in the

Cost–benefit analysis of screening programme for diabetic retinopathy in Bulgaria

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Late‐diagnosed diabetic retinopathy (DR) is difficult and expensive to treat. Screening programmes can identify the disease early and reduce the costs of its future treatment. This study aims to analyse the cost–benefit of screening programmes for DR.

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

open access: yesActa Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated

Retinal Architecture in ​\u3cem\u3eRGS9-\u3c/em\u3e and ​\u3cem\u3eR9AP\u3c/em\u3e-Associated Retinal Dysfunction (Bradyopsia) [PDF]

open access: yes, 2015
Purpose To characterize photoreceptor structure and mosaic integrity in subjects with RGS9- and R9AP-associated retinal dysfunction (bradyopsia) and compare to previous observations in other cone dysfunction disorders such as oligocone trichromacy ...

Noninvasive imaging of the thirteen-lined ground squirrel photoreceptor mosaic. [PDF]

open access: yes, 2016
Ground squirrels are an increasingly important model for studying visual processing, retinal circuitry, and cone photoreceptor function. Here, we demonstrate that the photoreceptor mosaic can be longitudinally imaged noninvasively in the 13-lined ground ...

Characterising PRPF31‐associated retinal dystrophy: Clinical insights from baseline data in a natural history study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To characterise the baseline clinical features and genotypes of adults with pre‐mRNA processing factor 31 (PRPF31)‐associated retinal dystrophy (RD) enrolled in a prospective, multicentre 4‐year natural history study, and to explore correlations between selected baseline parameters.

Unilateral conjunctival ulcer due to Stenotrophomonas maltophilia infection

open access: yesIndian Journal of Ophthalmology, 2012
We report a case of unilateral conjunctival ulcer due to Stenotrophomonas maltophilia infection in an immunocompetent individual. A 44-year-old male presented with complaints of pain and yellowish discharge in the right eye for one week.

Neovascular age‐related macular degeneration without drusen

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To describe the clinical characteristics and 1‐year follow‐up of patients with neovascular AMD (nAMD) without drusen in either eye. Methods This is a multicentre retrospective cohort study in three tertiary referral centres in The Netherlands. We included patients of 55 years or older with nAMD in one or both eyes, without the presence
