Treatment options will vary depending on the individual and their needs.
Camouflage with makeup is often considered as a treatment for NOO and NOI, but achieving cosmetically acceptable skin colour matching can be difficult.
Laser is often the main treatment used for both these conditions. Quality(Q)-switched lasers (Nd:YAG (1064nm and/or 532nm), Ruby (694nm) or Alexandrite (755nm)) are usually used to lighten pigmentation, but several treatment courses are required. Newer picosecond lasers (755nm and 1064nm) may also be used.
If the eye is affected with pigmentation, a referral to an ophthalmologist may be necessary.
