Adaptive optics retinal imaging reveals S-cone dystrophy in tritan color-vision deficiency.
Tritan color-vision deficiency is an autosomal dominant disorder associated with mutations in the short-wavelength-sensitive- (S-) cone-pigment gene. An unexplained feature of the disorder is that individuals with the same mutation manifest different degrees of deficiency. To date, it has not been possible to examine whether any loss of S-cone function is accompanied by physical disruption in t...
متن کاملCone photoreceptor definition on adaptive optics retinal imaging
AIMS To quantitatively analyse cone photoreceptor matrices on images captured on an adaptive optics (AO) camera and assess their correlation to well-established parameters in the retinal histology literature. METHODS High resolution retinal images were acquired from 10 healthy subjects, aged 20-35 years old, using an AO camera (rtx1, Imagine Eyes, France). Left eye images were captured at 5° ...
متن کاملAdaptive-optics imaging of human cone photoreceptor distribution.
We have used an adaptive-optics scanning laser ophthalmoscope to image the cone photoreceptor mosaic throughout the central 10 degrees -12 degrees of the retina for four normal subjects. We then constructed montages of the images and processed the montages to determine cone locations. Cone densities range from approximately 10,000 cones/mm2 at 7 degrees to 40,000 cones/mm2 at 1 degrees . The sm...
متن کاملAdaptive optics imaging shows rescue of macula cone photoreceptors.
Advanced age-related macular degeneration and inherited macular diseases remain largely untreatable. Clinical trials using stem cell transplantation have recently commenced and mark a further step in introducing cellular therapy for these diseases. Earlier techniques such as macular translocation and autologous retinal pigment epithelium (RPE), namely, choroidal transplantation demonstrated res...
متن کاملSupernormal vision and high-resolution retinal imaging through adaptive optics.
Even when corrected with the best spectacles or contact lenses, normal human eyes still suffer from monochromatic aberrations that blur vision when the pupil is large. We have successfully corrected these aberrations using adaptive optics, providing normal eyes with supernormal optical quality. Contrast sensitivity to fine spatial patterns was increased when observers viewed stimuli through ada...
