Abstract:
AIM: To observe the manifestations and distribution patterns of visual field in non-arteritic anterior ischemic optic neuropathy(NAION).METHODS: Retrospective observational study. The investigation encompassed 183 patients(246 eyes)diagnosed with NAION who were evaluated at the Neuro-Ophthalmology/Acupuncture Department within the Eye Hospital, China Academy of Chinese Medical Sciences from June 2018 to December 2023. Recorded clinical data covered demographic details, incidence, disease duration, presence of systemic diseases, and histories of tobacco and alcohol use, along with best-corrected visual acuity(BCVA), visual field index(VFI), type of visual field defect, and thickness of the peripapillary retinal nerve fiber layer(pRNFL).RESULTS: A total of 183 patients(246 eyes)were enrolled. The cohort consisted of 101 males and 82 females; 120 exhibited unilateral symptoms, while 63 showed bilateral symptoms, with a mean age of 56.20±9.78 years(range 29-81 years). The types of visual field defects observed were varied: 90 eyes(36.6%)had diffuse loss, 63 eyes(25.6%)experienced inferior hemifield loss, 32 eyes(13.0%)displayed ring scotomas, 22 eyes(8.9%)had arcuate scotomas, 11 eyes(4.5%)presented with quadrant defects, 15 eyes(6.1%)had sectorial or wedge defects, and 13 eyes(5.3%)showed superior hemifield loss. The BCVA(LogMAR)and VFI of patients with diffuse visual field loss were poorer than patients with other types of visual defects(all P<0.05). There were statistically significant differences in visual field defects among patients of different genders and ages(all P<0.05). However, history of hypertension, diabetes, hyperlipidemia, sleep apnea and other systemic diseases, history of smoking and alcohol, and course of disease did not show specificity in the NAION visual field(all P>0.05).CONCLUSION:NAION manifests with a broad spectrum of visual field impairments across different genders, age, and levels of visual functionality. Extensive future research is necessary to identify additional reasons influencing the types of visual field damage in NAION.
