Abstract

Aims To evaluate the long-term progression of quiescent type 1 choroidal neovascularisation (CNV) associated with age-related macular degeneration (AMD) or with pachychoroid disease. Methods All cases of quiescent type 1 CNV with a minimum follow-up of 12 months seen at the Department of Ophthalmology of University Paris Est, Creteil and at the Centre Ophtalmologique de l'Odeon, Paris, between June 2009 and December 2018 were retrospectively reviewed. Optical coherence tomography angiography (OCT-A) of eyes not showing CNV activation during 24 months was evaluated for quantitative analyses of CNV status biomarkers (fractal dimension, lacunarity, vessel density, aspect ratio, CNV area). Results A total of 67 eyes (65 patients, 43 females, mean age 76.63±9.7 years) with quiescent CNV and a mean follow-up of 49.56±27.3 (12-112) months were included. Of 28 eyes showing activation of quiescent CNV, 12 eyes with pachychoroid-associated CNV showed reduced visual loss (-3.28 ETDRS letters, p=0.7 vs -13.03 ETDRS letters, p=0.02), greater choroidal thinning (-59.5 μm, p=0.03 vs - 16.36 μm, p=0.3) and needed less antivascular endothelial growth factor intravitreal injections (IVI) (0.09 vs 0.21, p=0.01) than 16 eyes with AMD-associated CNV. CNV area was the only OCT-A biomarker to significantly change during 24 months in inactive quiescent CNV (+29.5%, p=0.01, in pachychoroid group and +27.1%, p=0.03, in the AMD group). Conclusion In the long-term follow-up, inactive quiescent CNV showed an increase of CNV area without significant changes of the other OCT-A biomarkers. Quiescent type 1 CNV undergoing activation showed greater response to IVI when associated to pachychoroid.
