Proparacaine effects on corneal reepithelialization in vivo. Fluorescein staining images show the comparative reepithelialization process in rabbit cornea after addition of regular (0.5%) and diluted (0.05%) proparacaine at day 3. Scale bar = 3.0 mm. Rabbit cornea showing the epithelialization baseline in the groups of regular proparacaine (A), diluted proparacaine (B), regular proparacaine without antibiotics (C), diluted proparacaine without antibiotics (D), regular proparacaine with antibiotics (E), and diluted proparacaine with antibiotics (F). Scale bar = 100 μm. Color images are available online.
