Age-related cataracts are classified into three types: nuclear sclerotic, cortical, and posterior sub–capsular. As a person ages, any of these three types can develop over some time.
Nuclear Sclerotic Cataracts– this is the most common type of age-related cataract. It happens as a result of hardening and yellowing of the lens over some time
Cortical Cataracts– known as the white opacity, or the cloudy areas, that develop in the lens cortex, which is in the outside edge of the lens
Posterior Sub–capsular Cataracts– generally form a small opaque or cloudy area on the back surface of the lens. It is known as “sub-capsular” due to its form beneath the lens capsule, which is a tiny sac, that surrounds the lens which holds it in place.
The common symptoms of age related cataracts may include:
- Cloudy and blurry vision
- Difficulty seeing at night
- Colors seem to appear faded
- Hypersensitivity to glare
- Halos surrounding lights
- Experiencing double vision in the affected eye
- Often changes in prescription glasses
Other common types of leg ulcer include:
- Arterial leg ulcers
- Diabetic leg ulcers
- Malignant leg ulcers
- Traumatic leg ulcers
- Vasculitic leg ulcers
Ulcers in the foot are usually caused by diabetes.
Itching, pain, and swelling in the affected leg are characteristic symptoms of a venous leg ulcer.
Discoloration, hardening of the skin around the ulcer, and presence of a foul-smelling discharge may also be present when you have a venous leg ulcer.
If you have a venous leg ulcer, you may exhibit the following conditions:
- discoloration and darkening of the skin around the ulcer
- swollen ankles
- red, flaky, scaly and itchy skin on your legs
- swollen and enlarged veins on your legs
- hardened skin around the ulcer, which may make your leg feel hard
- a heavy feeling in your legs
- an unpleasant and foul-smelling discharge from the ulcer
- aching or swelling in your legs
Signs of an infection
Opportunistic pathogens could cause secondary bacterial infections due to the ulcer.
Symptoms of an infected leg ulcer may include:
- a green or unpleasant discharge coming from the ulcer
- redness and swelling of the skin around the ulcer
- worsening pain
- an unpleasant smell coming from the ulcer
