Ocular signs and symptoms provide clinical clues to many of the more common metabolic and nutritional disorders seen in older adults. Diabetes mellitus can affect all parts of the eye and orbit. Complications include refractive visual loss, macular edema, retinopathy, increased risk of fungal infection, and diplopia. In patients with gout, urate crystals may precipitate in the eye and cause conjunctivitis, uveitis, or scleritis. Other problems are seen with Wilson's disease, hyperlipidemia, and albinism. Nutritional disorders usually arise from malabsorption, gastrointestinal surgery, and alcohol abuse. Deficiencies in vitamins A, B1 (thiamine), B12, and C may be manifest in the eye.
