Diabetic Retinopathy: Causes, Screening and Treatment
Diabetic retinopathy is the most common cause of new blindness in working-age adults in developed countries, caused by chronic hyperglycaemia damaging retinal blood vessels. This guide covers the progression from non-proliferative to proliferative retinopathy and macular oedema, how retinal screening saves sight, and treatment with laser, anti-VEGF injections, and vitrectomy surgery.
Age-Related Macular Degeneration (AMD): Causes and Treatment
Age-related macular degeneration is the leading cause of severe vision loss in adults over 50 in developed countries, destroying central vision through drusen accumulation, geographic atrophy, or choroidal neovascularisation. This guide covers dry and wet AMD, how anti-VEGF injections have transformed wet AMD treatment, and monitoring with OCT and Amsler grid.
Glaucoma: The Silent Thief of Sight
Glaucoma is a group of eye diseases in which elevated intraocular pressure progressively damages the optic nerve, causing irreversible visual field loss. It is the leading cause of irreversible blindness worldwide. This guide covers open-angle and angle-closure glaucoma, how elevated IOP damages the optic nerve, diagnostic tests, eye drop therapy, laser, and surgery.
Cataract: Causes, Symptoms and Surgery
A cataract is a clouding of the eye's natural lens, causing progressive blurring of vision and the leading cause of reversible blindness worldwide.
