hopefully its just an eye poke injury as opposed to an abcess, but you need to get Marjorie to a vet ASAP, she needs checking. the eye has probably been damaged & started to ulcerate, there is the possibility of a foreign body lodged under her eyelid/in her eye. the weeping is the bodies reaction to try & flush the eye & rid it of unwanted debris (be it dust or grass seed etc).
a vet will be able to remove anything causing damage to the eye & give her painkilling eyedrops to do it. She will probably need either Tiacil or fucalthmic? spelling? eyedrops.
usually an orange die is put into the eye & a light shone into it to see if it has been damaged.
Ask the vet to give you painkillers as it is probably very painful- i know what its like to have an eyelash or a grain of sand in my eye ... hurts like hell!
try boiling about an egg cup full of water & add a pinch of salt to it, then let it cool. drip some of it into marjories eye if you can, if you have a new/clean syringe use that, if not have a strip of kitchen roll dipped into the saltwater & drip in that way. it should help to soothe &clean it, until you get to a vets.
if its an eye poke or foreign body any local vet should be able to treat it, although it may have emergency hours as its a saturday or only open in the morning as mine is.
if it is an abcess causing the eye to bulge, the vet will be able to tell you this & maybe refer you to a specialist or as helen says get him to the cat & rabbit clinic. (piggy trains can sometimes be arranged for transport where members kindly drive the guineas to vets/new homes if the owners dont have transport.. contact stewybus if needed)
one of mine had a bulging eye years ago & i was warned it may rupture & she may lose the eye, it turned out to be a very fine grass seed strand lodged round her eyeball, this was removed & it took about 7-10 days to go back to normal when being treated with drops.
please get her treated as a matter of urgency if the eye is bulging though, complications & serious implications (even eye removal) can result if not treated quick enough.
good luck with an appointment, healing vibes & keep us updated.
