In Brief Purpose: This study was designed to examine choroidal thickness in patients with diabetes using spectral-domain optical coherence tomography. Methods: Forty-nine (49 eyes) and 24 age-matched normal subjects underwent high-definition raster scanning tomography frame enhancement software. Patients were classified into 3 groups: 11 mild or moderate nonproliferative diabetic retinopathy no macular edema, 18 20 treated proliferative edema (treated retinopathy). Choroidal measured from the posterior edge of retinal pigment epithelium choroid/sclera junction at 500-μm intervals up 2,500 μm temporal nasal fovea. Results: Reliable measurements obtainable 75.3% eyes examined. Mean showed a pattern thinnest choroid nasally, thickening subfoveal region, thinning again temporally diabetes. thinner (63.3 μm, 27.2%, P < 0.05) (69.6 30.0%, 0.01), compared subjects. There difference between Conclusion: is altered may be related severity retinopathy. Presence associated significant decrease thickness. A retrospective by demonstrates that subjects, clinically edema.
