What is the likely cause of the loss in vision?

Age-related macular degeneration sees the atrophy of the macular leading to the loss of rods and cones. This occurs at the centre of the retina leaving the periphery unaffected.
Papilloedoma- This occurs when the optic disc protrudes outward due to raised inter-cranial pressure.
Glaucoma- Inward 'cupping' of optic disc due to raised intraocular pressure.
Malignant hypertension- Capillaries in the retina burst, optic disc bulges forward.
Cataract- Lens becomes cloudy.
