NA-AION Risk Factors: New Perspectives
Recruiting
Trial ID: NCT05305079
Purpose
The purpose of the study is to use new diagnostic methods (OCT and OCT-A) to shed light on
risk factors for the development of NA-AION. The risk factors we are focusing on are
comorbidities along with anatomical and vascular characteristics of the optic nerve.

Eligibility
Inclusion Criteria:
1. Diagnosis of first episode of NA-AION in study eye with symptom onset within 14 days
prior
2. Subject age: Age >10
3. NA-AION diagnosis requires:
- disc edema seen and documented by site PI
- visual field defect in the study eye consistent with NA-AION and mean deviation
worse than 3.0 dB using the study visual field examination protocol
- relative afferent pupillary defect (unless the fellow eye had previous NA-AION or
other optic nerve or retinal disease that is not exclusionary)
Exclusion Criteria:
1. Previous episode of NA-AION in the study eye only
2. Intraocular pressure of >21 mm Hg in the study eye
3. Clinical or pathological evidence of giant cell arteritis
4. Diseases that may affect the optic nerve: glaucoma, multiple sclerosis, Alzheimer
disease, and Parkinson disease. Evidence of optic disc drusen and optic nerve
hypoplasia are not exclusion criteria given they are important parts of the study. We
will not exclude significant retinal diseases, since they may be related to underlying
etiologies giving rise to ODD, such as macular degeneration, retinal dystrophies, but
eyes with significant retinal diseases will be analyzed separately.
