LIMITS OF THE OCT RETINAL MAPPING
The management of AMD is largely based upon OCT evaluation of the macula. The retinal-mapping program of Stratus OCT (Carl Zeiss Meditec, Dublin, CA, USA) calculates the retinal volume of the central region between the retinal surface and the retinal pigment epithelium (RPE). In this study, Krebs et al tested whether the lines indicating the retinal surface and the RPE were positioned correctly by the threshold algorithm. Overall, only in 57.1% of scans of 233 eyes (117 patients) were both lines positioned correctly. False-positioned lines were recorded in 9.0% due to low scan quality and in 33.9% due to a doubled or interrupted hyper-reflective band of the RPE. The authors suggest that a manual correction of false-positioned lines would be needed to improve accuracy.

TETRAPEPTIDE EYE-DROPS FOR NEUROTROPHIC KERATOPATHY
Combination of substance P-derived peptide (FGLM-amide) and insulin-like growth factor-1 (IGF-1)-derived peptide (SSSR) stimulates rabbit corneal epithelial migration. 26 eyes (25 patients) with persistent corneal epithelial defects associated with neurotrophic keratopathy were treated by administration …
