Abstract

Introduction: Toxic optic neuropathy is defined as the damage caused by a toxin to the optic nerve fibers. There is a vast list of toxins that may lead to optic neuropathies. One of the toxins among this list is tobacco. Gutka being an oral form of tobacco, however, has not been previously related to optic neuropathy. Case presentation: We present a case of a 22-year-old male who presented with decreased far vision and gradually increasing photophobia. He had a history of gutka usage, a form of smokeless tobacco. Investigations revealed a central scotoma on FOV, a swollen optic disc on OCT and deranged Liver function tests. A diagnosis of RIGHT + LEFT optic neuropathy secondary to a chemical toxic was made, which in this case, was gutka. Conclusion: Consumption of gutka can lead to irreversible toxic optic neuropathy.
