“…5 Additional reports have added to our knowledge of phototoxicity by showing retinal damage secondary to the experimental application of light using slit lamp ophthalmoscopy or indirect ophthalmoscopy. Retinal damage secondary to the use of the operating microscope for cataract surgery [6][7][8][9][10][11][12][13][14][15] or endoillumination during vitreoretinal surgery [16][17][18][19] has served as further evidence of phototoxicity. The application of light in the form of lasers has been used therapeutically to induce injury to the retina for the treatment of such disease processes as diabetic retinopathy, choroidal neovascularization, and the treatment of various intraocular neoplasms.…”

The ability of light to enact damage on the neurosensory retina and underlying structures has been well understood for hundreds of years. While the eye has adapted several mechanisms to protect itself from such damage, certain exposures to light can still result in temporal or permanent damage. Both clinical observations and laboratory studies have enabled us to understand the various ways by which the eye can protect itself from such damage. Light or electromagnetic radiation can result in damage through photothermal, photomechanical, and photochemical mechanisms. The following review seeks to describe these various processes of injury and many of the variables, which can mitigate these modes of injury.

“…Harada and coworkers [9] described three patients with 'light-induced retinopathy' when a video recording device was used in connection with an operating microscope. Robertson and Feldman [10] demonstrated a cause-and-effect relationship between the light of an operating microscope and macular lesions in human eyes. They observed a photic retinopathy in the eyes of two patients after 60 minutes of exposure to the light of an operating microscope.…”

Intraoperative retinal light damage reflected in electrophysiologic data

et al. 1991

In a series of 30 unilaterally pseudophakic patients, electroretinograms and electrooculograms were recorded 6 months postoperatively. The unoperated on fellow eyes served as controls. High intraoperative retinal light exposure (3.4-7.3 mW/cm2, Zeiss OPMI6 operating microscope) caused a substantial reduction of electrophysiologic potentials. Light protection prevented deterioration of electroretinogram and electro-oculogram potentials; reducing the bulb voltage, tilting the axis of illumination, filtering short wavelengths and the use of light shields resulted in 4-log-unit lower intensities (0.8-3.7 microW/cm2).

“…However, the light from the microscope can induce retinal pathology, so-called phototoxic retinopathy. [5][6][7][8][9][10][11][12][13][14] The risk for developing phototoxic retinopathy increases with wavelengths between 400 nm and 500 nm, and the most hazardous wavelength ranges from 435 to 440 nm. 15,16 The surgical microscope emits light in the electromagnetic range between 400 nm and 500 nm.…”
