I hope that the drops do the trick for your OH and stop the blood vessel leak. I suppose that they put drops in both eyes as they can still tell then if anything untoward is happening in his right eye, pity that he ends up with a bad headache afterwards though. Good news that he will be referred to the Glaucoma dept, is that nearer to where you live?
My OH also is under the Glaucoma dept and has drops every night. I put them in for him though as he has to have one drop in each eye every night and a bottle containing a months supply is only 2.5ml (half a teaspoonful), if I left him to do it himself the bottle would be empty after the first week as he gets more down his face than in his eyes.
Good to hear that the MOT's went well though. The festive season can certainly play havoc with the "healthy eating" intentions
