Comparison of SS-OCT and SD-OCT in polypoidal choroidal vasculopathy

Swept source OCT (SS-OCT) is known to have a longer wavelength than spectral domain OCT (SD-OCT), allowing deeper penetration into retinal and choroidal layers. The aim of this study was to investigate whether SS-OCT is superior to SD-OCT in imaging...

Retinal morphology after PASCAL PRP treatment

The authors of this prospective cohort study set out to report the changes on Spectral Domain-OCT of PASCAL panretinal laser photocoagulation (PRP) treatment for proliferative diabetic retinopathy (PDR) or severe nonproliferative DR (NPDR) and the retinal morphology, from one hour...

OCTA in geographic atrophy

In this article the authors aim to give an overview of the current literature concerning the application of OCT-A in geographic atrophy (GA). GA is a disease characterised by loss of outer retinal layers including photoreceptors, degeneration of the retinal...
