Retinal Burns Occurring at Cataract Extraction

Retinal light toxicity

“…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.…”

Operating Microscope-Induced Retinal Phototoxicity During Pars Plana Vitrectomy

“…He under¬ went a pars plana vitrectomy using a Zeiss operating microscope with tungsten fila¬ ment internal illumination and an ultravi¬ olet filter on April 4,1987. The time esti¬ mated for sclerotomy closure was not longer than 15 minutes.…”

Three cases with light-induced retinopathy

“…In such a situation with direct involvement of the fovea, vision was ameliorated nonetheless from 0,3 finally to 0,5 (7), whereas it remained at the level of 0,1 in one of 12 cases of Bordrey et al (9) wherein the lesions were situated near the fovea. Visual prognosis of phototraumatic lesions due to light from operating microscope depends entirely upon their localizations as to the fovea.…”

“…Localization of phototraumatic lesions was, in the majority of cases reported in the literature, superior, inferior or temporal to the fovea [6,7,8,9]. Their ophthalmoscopic appearance was, in overwhelming number of cases [5,6,7], usually discrete, isolated, of oval shape, 1 to 1,5 disc diameter in size.…”
