Purpose:
To report the 5-year results of chorioretinal atrophy (CRA) progression in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC).
Methods:
A retrospective study included PIC/MFC patients with secondary CRA formation. The area of CRA was measured and the progression rate was calculated. Multiple regression analysis was performed to investigate risk factors associated with CRA progression.
Results:
Forty-five eyes of 36 patients were included. The mean CRA size significantly increased after an average of 4.83 years of follow-up with progression rate of 0.69 mm2/year. Moreover, we had identified the axial length and initial PIC lesion number as significant risk factors for CRA progression.
Conclusion:
Significant CRA enlargement is noted in PIC/MFC patients after 5 years of follow-up. The progression rate is associated with axial length and initial PIC numbers. Aggressive treatment is suggested for eyes with more initial lesion numbers and longer axial length to control the faster CRA progression.
