Blurred Disc Margins

We describe a case of a young patient referred to the neuro-ophthalmology clinic with 'blurred disc margins bilaterally' and 'RNFL thickening.' The case focuses on pitfalls associated with workup for this presentation, before revealing the patient's ultimate diagnosis and ongoing management.

Eye Swelling and Decreased Vision in a Patient With Autism O ur UPFRONT case describes an 8-year-old girl with severe autism spectrum disorder who presents with worsening eyelid swelling, decreased vision, and new exotropia for 1–2 months. Examination in the clinic, significantly limited by cooperation, revealed dry eye, and topical cyclosporine was started. Subsequent examination was notable for difficulty walking, needing to feel the area around her feet, and a complete relative afferent pupillary defect (rAPD) on the right. Sedated MRI showed no compressive lesions, but abnormal bone marrow signal was noted. Examination under anesthesia (EUA) revealed conjunctival keratinization, temporal optic nerve pallor, and attenuated retinal vessels with a salt and pepper fundus. Laboratory testing confirmed the final diagnosis of vitamin A and B12 deficiencies (both undetectable in serum; among other deficiencies) secondary to very restrictive eating habits (exclusively chicken nuggets, Cheerios, and fries), which were revealed by more detailed history obtained immediately after the EUA. The patient underwent admission, urgent gastrointestinal (GI) and nutrition consults, and parenteral repletion.

Movie-like episodes of previously seen visual stimuli would play out in his left visual field long after the stimuli were removed. UPFRONT Case: J Neuro-Ophthalmol 2023; 43: e63-64 John O. T.

These episodes were consistent with kinetic hallucinatory palinopsia, believed to be secondary to a right anterior occipital lobe infarct causing partial seizures.
