ABSTRACT
PURPOSE:
To compare the characteristics of optical coherence tomography in eyes with treatment-naïve typical neovascular age-related macular degeneration (typical nAMD), polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP).METHODS:
One hundred fifty-three eyes newly diagnosed with exudative AMD were retrospectively collected. All study eyes were classified into three subtypes typical nAMD, PCV, and RAP. Subfoveal choroidal thickness (SFCT) was measured using enhanced depth imaging optical coherence tomography (EDI-OCT). Central macular thickness (CMT) and other OCT features including intraretinal cystoid fluid and subretinal fluid were also evaluated in all eyes. SFCT, CMT and other OCT features were compared among the three subtypes of exudative AMD.RESULTS:
Seventy-four eyes with typical nAMD, 55 eyes with PCV, and 24 eyes with RAP were included. SFCT was significantly thickest in PCV and thinnest in RAP (p < 0.001). RAP showed the thickest CMT and the highest frequency of intraretinal cystoid fluid (p = 0.004, p < 0.001, respectively).CONCLUSIONS:
In patients with exudative AMD, different characteristics of OCT were observed according to the three subtypes. Identification of OCT characteristics could help differentiate the subtypes of exudative AMD.
