That's a fascinating case Walaa, and well-documented as far!
Both eye issues are cortex-related, and to me they seem to be driven by territorial conflicts of social position and autonomy.
According to ophtalmologist Dr Kwesi, the retina is connected to feelings of guilt and shame - this seems to fit her case. A tear in the retina may appear during stress phase (tissue minus) but also during regeneration A (swelling) or healing peak.
She has seen her daughter go down the "wrong way" of a bad relationship (just like her own), and divorce means a social downgrade to her. 
Her hypertension (sympathetic stress reaction) shows it put her into severe stress. The vertigo is often a sign of the fear of losing control ("to see someone fall" according to Dr Hamer, which I'd take figuratively here).
The cataract is a visual separation, similar to losing the color in life, and it develops in stress phase.

Insufficiency in blood supply to the brain is a function reduction and seems like chronic repair cycles of the blood vessels to me, reflecting her fight with life and marriage?

To focus on her (and also her daughter's) autonomy seems like a good direction, and to discard the doubts about right and wrong. What if we never make a fault, because it's the only thing that could happen?
Her beliefs "It’s important to be totally independent " and "How people see you and what they say about you is important and you have to keep a good image and make an effort for this." are a mismatch. How can one be both totally independent while being dependent on other people's opinion? This is something to review with her.

Can she imagine what maintains joy and contentedness in her life, apart from "normalty"? The META-meanings suit her perfectly, but she may need help to put them into practice...
