Foveal cone loss in tamoxifen maculopathy: a case report

Journal of Medical Case Reports, 2023
Background Tamoxifen is used in low dose concentrations (20–40 mg per day) as a therapy for breast cancer but is known to have ocular side effects. In this case report, the foveal cone integrity in a tamoxifen-treated patient who complained of a small ...

Dysflective cones: Visual function and cone reflectivity in long-term follow-up of acute bilateral foveolitis. [PDF]

, 2017
PURPOSE:Confocal adaptive optics scanning laser ophthalmoscope (AOSLO) images provide a sensitive measure of cone structure. However, the relationship between structural findings of diminished cone reflectivity and visual function is unclear.

Microscopic Inner Retinal Hyper-reflective Phenotypes in Retinal and Neurologic Disease [PDF]

, 2014
Purpose. We surveyed inner retinal microscopic features in retinal and neurologic disease using a reflectance confocal adaptive optics scanning light ophthalmoscope (AOSLO). Methods. Inner retinal images from 101 subjects affected by one of 38 retinal or

Adaptive optics scanning laser ophthalmoscopy

Optics Express, 2002
We present the first scanning laser ophthalmoscope that uses adaptive optics to measure and correct the high order aberrations of the human eye. Adaptive optics increases both lateral and axial resolution, permitting axial sectioning of retinal tissue in vivo.

High resolution adaptive optics imaging complements standard spectral domain optical coherent tomography in retinal diseases with micro-structural details: a case series

Vision Pan-America, 2015
Purpose: To evaluate if high resolution adaptive optics confocal scanning laser ophthalmoscopy (AO-SLO) can be used as an adjunct complementary diagnostic tool to spectral domain optical coherent tomography (SD-OCT) in characterizing three macular ...

Image stabilization for scanning laser ophthalmoscopy

Optics Express, 2002
A scanning laser ophthalmoscope with an integrated retinal tracker (TSLO) was designed, constructed, and tested in human subjects without mydriasis. The TSLO collected infrared images at a wavelength of780 nm while compensating for all transverse eye movements.

Differential amplitude scanning for retinal imaging: a theoretical study [PDF]

, 2010
A differential amplitude scanning system for ophthalmoscopy is described theoretically. The differential scanning ophthalmoscope (DSO) samples the retina with two laterally displaced spots.

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

, 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 ...

Intravitreal Administration of Human Bone Marrow CD34+ Stem Cells in a Murine Model of Retinal Degeneration. [PDF]

, 2016
PurposeIntravitreal murine lineage-negative bone marrow (BM) hematopoietic cells slow down retinal degeneration. Because human BM CD34+ hematopoietic cells are not precisely comparable to murine cells, this study examined the effect of intravitreal human

Assembly and proving of a wave front sensing confocal Scanning Laser Ophthalmoscope [PDF]

, 2007
Confocal Scanning Laser Ophthalmoscopy is used to image the fundus of the living eye. In theory, this technique can be used to observe single cells of the retina. Unfortunately, vision of most eyes is decreased by higher-order aberrations, that cannot be
