No Light Perception Vision in Neuro-Ophthalmology Practice

Background: To determine differential diagnosis and visual outcomes of patients with no light perception (NLP) vision related to neuro-ophthalmic conditions. Methods: Retrospective case series of patients seen at tertiary neuro-ophthalmology practices. Patients were included if they had NLP vision any time during their clinical course. Outcome measures were final diagnosis, treatment, and visual outcome. Results: Seventy-two eyes of 65 patients were included. The average age was 57.6 (range 18-93) years, and 58% were women. The Most common diagnosis (21 patients) was compressive optic neuropathy (CON) with meningioma being the most common culprit (12). Other diagnoses included optic neuritis (ON) (11 patients), infiltrative optic neuropathies (8), posterior ischemic optic neuropathy (7), nonarteritic anterior ischemic optic neuropathy (4), arteritic anterior ischemic optic neuropathy (3), ophthalmic artery occlusion (3), nonorganic vision loss (3), radiation-induced optic neuropathy (2), cortical vision loss (1), retinitis pigmentosa with optic disc drusen (1), and infectious optic neuropathy (1). Ten patients recovered vision: 7 ON, 2 infiltrative optic neuropathy, and 1 CON. Corticosteroids accelerated vision recovery in 7 of the 11 patients with ON to mean 20/60 (0.48 logMAR) over 9.0 ± 8.6 follow-up months. Eleven patients deteriorated to NLP after presenting with at least LP; their diagnoses included CON (3), ophthalmic artery occlusion (2), infiltration (2), ON (1), posterior ischemic optic neuropathy (1), arteritic anterior ischemic optic neuropathy (1), and radiation-induced optic neuropathy (1). Conclusions: NLP vision may occur because of various diagnoses. Vision recovery was mainly seen in patients with ON. Serious systemic conditions may present or relapse with NLP vision, which clinicians should consider as an alarming sign in patients with known malignancies
