The worsening foggy vision and night blindness are likely due to the natural progression of Retinitis Pigmentosa, rather than your past cataract surgery. To help manage these symptoms, options include:- Slowing progression: High-dose Vitamin A palmitate, lutein, or omega-3 supplements can sometimes slow the disease, under medical supervision.- Treating swelling: Carbonic anhydrase inhibitors (like dorzolamide drops or acetazolamide tablets) can treat swelling in the retina that causes fogginess.- Gene therapy: Treatments like voretigene neparvovec may be suitable for specific genetic types.- Low-vision aids: Specialised lenses can help manage frequent prescription changes. Please discuss these tailored options with your ophthalmologist.
