Tunnel vision [Gun barrel vision, tubular vision]:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient when he first noticed a loss of peripheral vision, and have him describe the progression of vision loss. Ask him to describe in detail exactly what and how far he can see peripherally. Explore the patient’s personal and family history for ocular problems, especially progressive blindness that began at an early age.
To rule out malingering, observe the patient as he walks. A patient with severely limited peripheral vision typically bumps into objects (and may even have bruises), whereas the malingerer manages to avoid them.
If your examination findings suggest tunnel vision, refer the patient to an ophthalmologist for further evaluation.

Carpal tunnel syndrome:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Physical examination reveals decreased sensation to light touch or pinpricks in the affected fingers. Thenar muscle atrophy occurs in about half of all cases of carpal tunnel syndrome, but it’s usually a late sign. The patient exhibits a positive Tinel’s sign (tingling over the median nerve on light percussion) and responds positively to Phalen’s wrist-flexion test (holding the forearms vertically and allowing both hands to drop into complete flexion at the wrists for 1 minute reproduces symptoms of carpal tunnel syndrome). A compression test supports this diagnosis: A blood pressure cuff inflated above systolic pressure on the forearm for 1 to 2 minutes provokes pain and paresthesia along the distribution of the median nerve.
Electromyography and nerve conduction velocity detect a median nerve motor conduction delay of more than 5 milliseconds. Other laboratory tests may identify the underlying disease.
