Acute zonal occult outer retinopathy in Japanese patients: clinical features, visual function, and factors affecting...

Area of Science:

• Ophthalmology
• Retinal Diseases
• Visual Function Research

Background:

• Acute zonal occult outer retinopathy (AZOOR) is an idiopathic retinal disorder.
• Understanding AZOOR's clinical course and visual outcomes is crucial for patient management.

Purpose of the Study:

• To evaluate clinical features of AZOOR in Japanese patients.
• To investigate the relationship between clinical features and visual function in AZOOR.

Main Methods:

• Retrospective analysis of 52 eyes from 38 Japanese AZOOR patients.
• Comparison of untreated eyes versus systemic corticosteroid-treated eyes.
• Multiple stepwise linear regression to identify factors affecting visual acuity (BCVA) and visual field (MD).

Main Results:

• Both untreated and treated AZOOR eyes showed significant visual improvement over time.
• Systemic corticosteroids improved best-corrected visual acuity (BCVA) and mean deviation (MD).
• Initial visual field defects, female sex, vitreous cells, and retinal atrophy impacted final visual function.

Conclusions:

• Japanese AZOOR patients demonstrate favorable visual outcomes.
• Spontaneous improvement and corticosteroid therapy contribute to visual recovery.
• Predictors of final visual function include initial visual field status, gender, and retinal changes.
