Here are the commons types of visual impairment
Thick film covers the eyes, sensitive to glare
The body is unable to produce enough insulin to convert sugar to energy, leading to a buildup of sugar in the blood. Diabetic retinopathy happens when blood vessels in the eye rupture and causes patches of blurry vision.
Glaucoma is a result of damaged optic nerves caused by the buildup of eye fluid and increased eye pressure. Glaucoma affects your side vision and can eventually cause tunnel vision.
Early Stage Glaucoma
Late Stage Glaucoma
Age-Related Macular Degeneration (AMD)
Above 50 yrs old, black spots appearing in central vision or straight lines looking wavy. Difficulties in reading or recognising faces. These are some common signs of age-related macular degeneration (AMD). AMD is an eye condition affecting your central vision.
There are two types of AMD – wet and dry. Wet AMD is caused by an abnormal growth of blood vessels in the eye, leading to the leakage of blood and proteins into the sensitive cells in the macula. This causes damage and vision loss. There is no exact cause of dry AMD but the condition occurs as the eye ages.
Retinitis Pigmentosa (RP)
‘Retinitis Pigmentosa (RP) is a group of inherited, degenerative eye conditions that affects the retina. People with RP may experience gradual loss of side vision and poor night vision, commonly starting from their teenage years.
Early Stage RP
Late Stage RP
Night Blindness in RP
