    Researchers compared IOP, basal tear secretion (BTS), reflex tear secretion (RTS) and corneal and anterior chamber parameters of 31 healthy volunteers during and one-month after Ramadan fasting. They found that fluid loading at the pre-dawn meal during Ramadan significantly increased IOP, BTS and RTS measurements. These values decrease remarkably at the end of 12 hours of fasting due to dehydration. IOP showed a diurnal variation of 2.45 mmHg (P<0.001) and BTS showed a 3.06 mm decrease (P=0.04) during the fasting period. No significant differences could be found in the corneal and anterior chamber parameters during fasting and non-fasting periods.
