The effect of fish consumption on macula structure and function of healthy individuals: an OCT and mfERG study

OBJECTIVE: The study was designed to investigate the potential effect of fish consumption on macular structure and function of healthy individuals. PATIENTS AND METHODS: The participants were Greek, who used to consume less than one portion of fish per week since their childhood. All participants underwent body mass index (BMI) measurements and ophthalmological examination. At their first examination, they were asked to consume at least 2 portions of fish per week over a period of 8 weeks, after which all the measurements were repeated. RESULTS: Eighteen healthy individuals (36 eyes) participated in this study. The central macular thickness was reduced, while the amplitudes in the foveal and parafoveal area were increased after the fish consumption. However, all measurements remained within the normal range at both visits. CONCLUSIONS: Regular fish consumption could enhance the structural and functional status of the macula.
