What are the complications of retinitis pigmentosa?
Possible Complications Peripheral and central loss of vision will occur over time. People with retinitis pigmentosa often develop cataracts at an early age. They may also develop swelling of the retina (macular edema). Cataracts can be removed if they contribute to vision loss.
What does retinitis pigmentosa cause?
Retinitis pigmentosa is a group of related eye disorders that cause progressive vision loss. These disorders affect the retina, which is the layer of light-sensitive tissue at the back of the eye . In people with retinitis pigmentosa, vision loss occurs as the light-sensing cells of the retina gradually deteriorate.
What causes PSC cataracts?
Posterior subcapsular cataracts are associated with aging, steroids, trauma, ionizing radiation, intraocular inflammation, diabetes, high myopia, retinitis pigmentosa, Refsum’s disease, and atopic dermatitis.
What causes fast growing cataracts?
Trauma-related cataracts are typically the most fast-growing type of cataracts. Radiation: Radiation-related cataracts, sometimes listed under trauma-related cataracts, occur after the lens has been exposed to radiation. Exposure to high levels of radiation can result in clouded vision in as little as two years.
Can stress cause cataracts?
Because emotional or psychological stress is associated with increased oxidant production and oxidative damage, long-term exposure to emotional or psychological stressors may enhance the risk of many diseases associated with oxidative stress, including cataracts.
How do you slow down retinitis pigmentosa?
A few options can slow your vision loss and may even restore some sight:
- Acetazolamide: In the later stages, the tiny area at the center of your retina can swell.
- Vitamin A palmitate: High doses of this compound may slow retinitis pigmentosa a little each year.
How do you slow down Retinitis Pigmentosa?
Is retinitis pigmentosa an autoimmune disease?
We conclude that although retinitis pigmentosa is genetically determined, patients develop autoimmunity against retinal tissue due to suppression of cell-mediated immunity. Association of rheumatoid factor in 8% of the cases further confirms the loss of homeostatic control owing to suppressed cell-mediated immunity.
What are the grades of cataracts?
Grading cataracts
| Cataract type | Grade 1 | Grade 3 |
|---|---|---|
| Nuclear | Mild | Pronounced |
| Cortical (by degree of intrapupillary space obscured) | 10% | 50%-90% |
| Posterior subcapsular (by degree of posterior capsule obscured) | 3% | 50% |
