Unintentional Staining of the Anterior Vitreous with Trypan Blue During Cataract Surgery

Letter to the Editor re: “Unintentional Staining of the Anterior Vitreous with Trypan Blue During Cataract Surgery”

“… 3 These toxic effects may not cause any fundus abnormalities but can be detected by an electrophysiological examination such as electroretinogram. In their study, Kayıkçıoğlu et al 1 reported that retinal toxicity was not observed in these patients. It seems that an electrophysiological test was not performed to detect possible retinal toxicity in their study, which may have caused the retinal toxicity to be overlooked.…”

“…We have read with great interest the article by Kayıkçıoğlu et al 1 ‘‘Unintentional Staining of the Anterior Vitreous With Trypan Blue During Cataract Surgery’’.The article describes a rare complication of phacoemulsification surgery: staining of the posterior capsule and anterior vitreous with trypan blue during phacoemulsification surgery. We thank the authors for their work and would like to make some contributions with respect to trypan blue toxicity of the retina, which can also be seen after vitrectomy with many vital dyes including trypan blue.…”
