Recently, our group found that levels of FABP4, FABP5 and FAs in vitreous fluid surgically obtained from patients with various retinal vascular diseases (RVDs), which are ocular complications associated with DM, HT and HL [7,8,9,10], were significantly increased compared with the levels in vitreous fluid obtained from patients with epiretinal membrane (non-RVD) [11]. The gene discussed is FABP5; the disease is diabetes mellitus.
