In 2004, the prevalence was estimated at 1.6 million US citizens by Friedman (2011) and the number only continues to rise. Ocular coherence tomography (OCT) has been a major diagnostic tool in the identification and management of ARMD since its inception. As spectral domain OCT has replaced time-domain OCT, more in-depth imaging has continued to help redfine this disease. This entity has been invaluable since the emergence of antivascular endothelial growth factor (VEGF) therapy for exudative disease although now it has also shown a more significant role in nonexudative disease. Parafoveal telangiectasia (PFT) is a similar appearing entity to ARMD leading to the two occasionally being confused with one another especially when PFT leads to choroidal neovascular membrane. This entity was originally described by Gass in 1982 and was previously detected by clinical exam and fluorescence angiography, but with spectral domain OCT (SD-OCT) it is more easily recognizable with less invasive testing. It shows OCT triad of thinning, loss of the IS/OS junction, and cystoids. Overall, SD-OCT has revolutionized the detection and the evaluation of progression/regression of ARMD and parafoveal telangiectasia. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
