Internal limiting membrane separation and posterior vitreous hyperreflective dots: novel OCT findings in Purtscher-like retinopathy

open access: yesBMC Ophthalmology
Background Purtscher or Purtscher-like retinopathy is diagnosed by retinal hemorrhages and areas of retinal whitening on fundus examination, as well as a reduction in visual acuity due to microvascular occlusion of the precapillary retinal arterioles. We

Retinal adaptation of Japanese common squid (Todarodes pacificus Steenstrup) to light changes [PDF]

open access: yes, 1985
The response of retinae of the Japanese common squid (Todarodes pacificus Steenstrup) was recorded in relation to various light intensities. In the light-adapted eye of common squid, the black pigment ascends to the external limiting membrance of the ...

RETRACTED ARTICLE: Verteporfin-induced formation of protein cross-linked oligomers and high molecular weight complexes is mediated by light and leads to cell toxicity

open access: yesScientific Reports, 2017
Verteporfin (VP) was first used in Photodynamic therapy, where a non-thermal laser light (689 nm) in the presence of oxygen activates the drug to produce highly reactive oxygen radicals, resulting in local cell and tissue damage.

Detailed Visual Cortical Responses Generated by Retinal Sheet Transplants in Rats with Severe Retinal Degeneration. [PDF]

open access: yes, 2018
To combat retinal degeneration, healthy fetal retinal sheets have been successfully transplanted into both rodent models and humans, with synaptic connectivity between transplant and degenerated host retina having been confirmed.

The function of photomechanical movements in the retina of the rainbow trout (Salmo gairdneri) [PDF]

open access: yes, 1982
1. The function of photomechanical movements in the retina of rainbow trout (Salmo gairdneri) was investigated by determining both the effect of light on the level of extractable visual pigment, and the electroretinographic b-wave sensitivity, during ...

Sunlight reflections from a solar power satellite on solar mirrors should not harm the eyes [PDF]

open access: yes, 1980
The potential hazard imposed by the reflection of the Sun's image by the solar power satellite (SPS) was examined. In the worst case, where the transmitter is assumed to be a perfect mirror reflecting the Sun's image normal to the atmosphere, the total ...

Retinal degeneration is rescued in transgenic rd mice by expression of the cGMP phosphodiesterase ß subunit [PDF]

open access: yes, 1992
The ß subunit of the cGMP phosphodiesterase (PDE) gene has been identified as the candidate gene for retinal degeneration in the rd mouse. To study the molecular mechanisms underlying degeneration and the potential for gene repair, we have expressed a ...
