| Purpose | To investigate epidemiological findings and clinical outcomes of patients diagnosed with Acute Retinal Necrosis (ARN), emphasizing the need for early diagnosis and effective treatment. |
| Methods | This retrospective study analyzed medical records of patients diagnosed with ARN at reference hospitals in São Paulo, Brazil, from 2017 to 2024. The American Uveitis Society’s criteria guided the diagnoses, focusing on clinical features like retinal necrosis with rapid progression and occlusive vasculopathy. |
| Results | The study involved 18 patients, predominantly female, with a mean age of 51.44 years. About 27.8% showed improvement in visual acuity, while 61.1% experienced a deterioration, and 11.1% maintained their initial visual acuity. The most common complication was retinal detachment, affecting 50% of the patients. Other complications included vitreous haze, retinal ischemia, and phthisis bulbi. |
| Conclusion | ARN poses significant risks of severe visual impairment, predominantly due to delayed diagnosis and treatment. Despite some patients showing improvement, the majority suffered from decreased visual acuity, with retinal detachment being notably prevalent. This study underscores the critical importance of prompt referral and management to improve visual outcomes. Further multicentric or long-term studies are needed to refine treatment protocols and enhance patient prognosis. |
