Inner nuclear layer cystoid spaces are a poor prognostic factor in typical age-related macular degeneration and polypoidal choroidal vasculopathy
We would like to address several challenges that have arisen from the study by Kang et al. , which are specifically summarized below.
Missing baseline data from the article by Kang et al. 
Anatomic lesions of neovascular maculopathy of the tAMD [choroidal neovascularization (occult/predominantly classic/minimally classic/mixed lesions), serous and/or hemorrhagic detachment of the neurosensory retina or RPE, cystic changes within neurosensory retina/inner nuclear layer, retinal hard exudates, subretinal and sub-RPE fibrovascular proliferation, disciform scar (subretinal fibrosis)]
Anatomic lesions of the PCV separately for the two subtypes of PCV (serosanguineous detachments of RPE and neurosensory retina, exudative changes, aneurismal polypoidal lesions with overlying atrophy of the pigment epithelium, abnormal branch vascular networks, vitreous hemorrhage, subretinal fibrosis, pigment...
