Caffeine produces a few physiological effects, including slightly raised blood pressure and increased heart rate. It is a vasoconstrictor (i.e. it affects blood vessels) and it also affects muscle contractility; these things, infact do make it possible for caffeine to have a slight effect on eye pressure. In a study of 63 adults, healthy young adults were given varying doses of caffeine, and in the high-dose group (taking 340mg caffeine) there was a statistically significant but relatively small rise of over 2mmHg after 90 minutes. Infact there was little change between groups when IOPs were measured only 30 minutes after drinking caffeine. Caffeine is in a number of products, including coffee, tea, coca cola, energy drinks and chocolate.
Here is a list of the approximate amounts of caffeine in various drinks and foods:
Coffee 140mg
Expresso (single shot) 106mg
Grande cup of coffee (16 oz) 300mg
Starbucks Tall coffee 260mg
Coke Zero 45mg
Diet coke 45mg
Fanta 0mg
Mountain Dew 54mg
Pepsi Max 69mg
Lipton iced tea 48mg
Green tea 25mg (typically there is less caffeine in green tea varieties)
Patients who have glaucoma or ocular hypertension, who are heavy coffee drinkers, or who have a high intake of caffeine, should be advised to limit their consumption.
Green tea has a relatively low caffeine content |

There is now evidence that magnesium is deficient in patients with glaucoma. In one Russian study, magnesium levels were found to be several fold lower. In normal subjects, levels were found to be about 180 mg/L whereas in glaucoma patients levels were around 18 mg/L. The role of magnesium supplementation is yet to be evaluated in detail; there is some concern about the toxicity of magnesium in patients with renal complaints. Magnesium deficiency may play a role in glaucoma by impairing mitochondrial function and activating NMDA receptors. One epidemiological study based on a dietary survey however has linked a higher intake of magnesium with an increased risk of glaucoma, so the data is quite hard to interpret really. http://www.ncbi.nlm.nih.gov/pubmed/22461101
Magnesium is found naturally in green vegetables including spinach, nuts and whole grains. It helps the release of energy from food, and is important in the development of healthy bones, nerves and muscles. A typical adult male requires about 400mg of magnesium a day, and an adult female around 300mg daily.
Severe magnesium deficiencies are infact rare. They are more likely in those who have Crohn's disease and kidney disease, also in those who abuse alcohol.

Discharge advice following glaucoma surgery (Mr Galloway patients)
The morning after surgery: wash your hands, remove shield, bathe eyelids with boiled, cooled water and cotton pads. Use new piece with each wipe. Wear eye shield for 7 nights. No heavy lifting for 2 weeks. A gritty or somewhat sharp feeling may be present in the days following surgery. This is normal, and can reflect a surface dryness or be due to some sutures. Sutures are often "dissolving", but can work their way loose. If, however, any significant eye ache develops, seek advice immediately.
DO NOT RUB YOUR EYE AT ANY STAGE FOLLOWING SURGERY
You may wear dark glasses if bright lights are uncomfortable.
