A 64-year-old male complained of poor visual gain following vitrectomy with trans-scleral fixation of posterior chamber intraocular lens (PCIOL) in his right eye (RE). The surgery lasted two and a half hours and a xenon light source was used for endoillumination. RE had a best corrected visual acuity (BCVA) of 6/36, centered PCIOL, and an amoeboid area of pigmentary alteration at the fovea. Short-wave autofluorescence showed well-demarcated perifoveal hyperautofluorescent areas with spectral domain optical coherence tomography showing loss of photoreceptors and retinal pigment epithelium (RPE) thickening. Diagnosis of microscope and endoilluminator light-induced phototoxic maculopathy was made., Despite a 6-week course of oral steroids, he continued to worsen. At 1-year follow-up he had a hyperpigmented foveal scar with BCVA of 4/60 [Figure 1]a,[Figure 1]b,[Figure 1]c,[Figure 1]d,[Figure 1]e,[Figure 1]f,[Figure 1]g,[Figure 1]h,[Figure 1]i. Use of spectral filters and mechanical barriers over the cornea helps to reduce its incidence.,
