A client complains that sometimes there appears to be gnats in his field of vision. The nurse realizes the client is talking about:
1. Floaters.
2. Conjunctivitis.
3. Nystagmus.
4. Strabismus.
Floaters.
Rationale: The vitreous gel is made up mainly of water with a collagen framework. The collagen network can be aggregated by vitreous collapse due to aging and form opacities, which cast shadows on the retina. These shadows are referred to as floaters. The client often describes this as seeing gnats or a fine filament floating in the line of sight. Conjunctivitis is an inflammation of the conjunctiva. The main symptom is a discharge from the eyes. Nystagmus is an involuntary tremor or jerky movement of the eyeball. Strabismus is a functional misalignment of the extraocular muscles that causes the eyes not to focus together.
