How do you distinguish between nuclear and cortical cataracts?

Nuclear sclerotic cataract (NS) – Cloudiness of the nucleus, the central portion of the lens. Cortical spoking cataract (CS) – Swelling of the cortex causing spoke/wedge-like peripheral cloudiness.

Is nuclear cataract serious?

If the nuclear sclerosis is severe enough, it’s called a nuclear cataract. The proteins in the lens start to clump, scattering light instead of allowing it to pass through. Cataracts cause about half of all blindness in the world, and nuclear cataracts are the most common type.

What does vision look like with cataracts?

Cataract Symptom: Blurry Vision

Blurry vision at any distance is the most common symptom of cataracts. Your view may look foggy, filmy, or cloudy. Over time, as the cataracts get worse, less light reaches the retina. People with cataracts may have an especially hard time seeing and driving at night.

What is an age related nuclear cataract?

Nuclear cataracts are a clouding and hardening of the lens center, resulting in blur, glare and other changes in vision. They are the most common type of cataract. In a study of people aged 75 years and older, the occurrence of nuclear cataract in at least one eye was 40%.

Can cataracts move around in the eye?

Some may stop progressing altogether after a certain point, but cataracts never go away on their own, and if they continue to grow they can cause blindness if left untreated. Although cataracts are not reversible, there are some things you can do that may help slow down the progression of cataracts.

What do early stage cataracts look like?

The symptoms of early-stage cataracts include mild eye blurriness and cloudiness, early sensitivity to light and glare, and an ever-increasing eye strain. Sudden headaches, seeing flashes of lights, sudden vision changes, and double vision could also be symptoms of early to immature stages of cataracts.

What is the rarest cataract?

Hyperferritinemia-cataract syndrome is an extremely rare genetic disorder characterized by the early onset of cataracts associated with persistently elevated levels of ferritin in the blood plasma. Ferritin is a protein that binds to iron and is used as an indicator of the body’s iron stores.

What is seeing halos around lights?
