OCT in Age Related Macular Degeneration (ARMD) and Polypoidal Choroidal Vasculopathy (PCV)
Optical Coherence tomography (OCT) has revolutionized the way we look at retinal disorders. The earliest version of OCT was the time domain OCT following which spectral domain OCT arrived. Advances such as enhanced depth imaging and swept source OCT have furthered our understanding of retinal disorders. Beginning from the early 90s , OCT has vastly improved the way we diagnose, prognosticate , treat and follow-up retinal disorders.(1) Why OCT? OCT has established itself as one the main imaging modalities in retinal conditions or macular disorders to be more specific. OCT is the most précised method measuring retinal thickness in-vivo.(1) Let us take age related macular degeneration (ARMD) as an example. Understanding the location of the neovascular membrane and its consequences such as intra/subretinal fluid can be clearly understood with the help of an OCT.(2) Prognostic factors such as integrity of the outer retinal layer , RPE alterations such as thickening or fragmentation and the
