Xerophthalmia and keratomalacia are public health problems of great magnitude which are usually associated with multiple vitamin and protein deficiencies. The authors report the case of a 27-year-old commune member who subjected herself to a bizarre protein and vitamin deficient diet for many months. This ultimately produced nyctalopia, xerophthalmia and keratomalacia with bilateral corneal perforation. Despite therapy, she remained comatose and expired shortly after admission. Ocular pathological changes included bilateral corneal melting with prolapse of intraocular contents, conjunctival epidermidalization, goblet cell atrophy and thinning of the outer nuclear layer of the retina. It is noted that ocular findings in pure avitaminosis A produced experimentalyy include epithelial atrophy followed by keratinization.

A 45-year-old man presented with longstanding poor vision in both eyes. His medical history was significant for a remote overdose of quinine. After the ingestion, he fell into a coma and on awakening was not able to see light out of both eyes. Several days later, his central vision began to gradually recover and continued to improve over the span of several months. Presently, he had 20/20 visual acuity in both eyes with severely constricted peripheral visual fields. There were bilateral iris transillumination defects, and both optic nerves were diffusely pale with attenuated vasculature and inner retinal thinning on ocular coherence tomography. We present a patient with the stereotypical findings and natural history of quinine toxicity, a rare and not widely known cause of toxic optic neuropathy and retinopathy.
