Aim: To observe the short term effects of coffee consumption on IOP and BP.

Methodology: In total 44 healthy subjects were included in the study that are based on inclusion and exclusion criteria. Baseline measurements of parameters like Intraocular pressure, Blood pressure, Central corneal thickness, Anterior chamber depth, Axial Length, Lens Thickness, Pupil Diameter were recorded in morning, after which subjects received one cup of coffee (200ml) which contain 2.29 gm of coffee powder (72.5 mg of caffeine). Post coffee consumption, the following parameters were measured after a same definite interval in all subjects and recorded.

Results: Mean Intraocular pressure and Blood pressure values were increased after coffee consumption, however not statistically significant when compared to before coffee consumption (p value>0.05). Anterior chamber depth was significantly increased at 1st hour and 2nd hour from the baseline (p value< 0.05) however, Lens Thickness was reduced significantly when compared from the baseline, at 1st hour and 2nd hour (p value< 0.05). Pupil Diameter, Central corneal thickness and Axial Length were not significant pre and post coffee consumption and there was no significant changes in Ocular pulse Amplitude and Ocular perfusion pressure values, pre and post coffee consumption (p value>0.05).

Conclusion: From above data, we can conclude that there was a significant increase in Anterior chamber depth and a significant decrease in Lens thickness after 1-2 hours of one cup of coffee consumption although Intraocular pressure and BP was not significantly affected by ingestion of a single cup of coffee in normal individual.

Intraocular pressure and BP was not significantly effected by ingestion of a single cup of coffee in normal individual although, we found a significant increase in ACD and significant decrease in LT after 1-2 hours of coffee consumption.
