“…This injury has been reported in individuals who have fixedly stared at the sun (solar retinitis) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] or a welding arc [20][21][22][23][24][25][26][27], usually for more than a few minutes. Photoretinitis is ophthalmoscopically observed as retinal changes such as edema, white spots, or holes, and is accompanied by symptoms such as decreased visual acuity, blurred vision and scotoma.…”

Visible light of short wavelength (blue light) may cause a photochemical injury to the retina, called photoretinitis or blue-light hazard. In this study, various light sources were evaluated for blue-light hazard. These sources include the sun, the arc associated with arc welding and plasma cutting, molten steel, iron and glass, the interior of furnaces, the arc or envelope of discharge lamps, the filament or envelope of incandescent lamps, the envelope of fluorescent lamps and light-emitting diodes. The spectral radiance of each light source was measured, and blue-light effective radiance and the corresponding permissible exposure time per day were calculated in accordance with the ACGIH (American Conference of Governmental Industrial Hygienists) standard. The sun, arc welding, plasma cutting and the arc of discharge lamps were found to have extremely high effective radiances with corresponding permissible exposure times of only 0.6-40 s, suggesting that viewing these light sources is very hazardous to the retina. Other light sources were found to have low effective radiances under the study conditions and would pose no hazard, at least for short exposure times.

It also demonstrates the efficiency of radiotherapy as a palliative treatment for subcutaneous eyelid leukaemic infiltration. References

“…In the largest series, half the eyes recovered 6/6 visual acuity, and about 10% were left with visual acuity less than 6/12 and persistent scotomata 1. This central visual impairment does not equate to blindness but may restrict choice of occupation in younger patients.…”

“…A partial eclipse may be visible from the north of Scotland to the north of Spain and from northern Poland to southern Italy. The eclipse will occur at the height of summer, as the sun nears its zenith, over some of the most densely populated regions of the world, and thus may be followed by an even greater incidence of retinal injury than reported after other recent eclipses 1 – 5…”
