After four hours in Ipswich hospital, we have learned that Mum does not have a problem with her retina. She merely has Posterior Vitreous Detachment, which means the jelly that makes up her eye is shrinking. The problems she’s been getting are the result of the shrinking jelly tugging on the retina and optic nerve. All should be well again in six to eight weeks. Back to London this afternoon, but for now it’s off to the pub for lunch!
