Answer:

Explanation:

LHON (Leber Hereditary Optic Neuropathy): Is a disease that is characterized by loss of vision in young adults.

Sickle cell anemia: Is a disease characterized by production of abnormally shaped red blood cells, that is, not round in shape as normal but are 'sickle' shaped or elongated/crescent shaped.
