The subjective symptom which most urgently leads a patient to seek medical assistance is pain. In nearly every case, this predominates in the mind and demands immediate relief. The pain may be so intense as to distract attention from other symptoms, even when they would otherwise cause great anxiety. For instance, in acute glaucoma, severe pain can overshadow vision loss until revealed during examination. Yet, pain is an unreliable guide for diagnosis, especially concerning headaches. When confined to a single organ, it is called toothache, earache, eyeache, etc., indicating local trouble but occasionally being reflexive and caused by issues elsewhere in the body. A headache may be slight or severe, acute or chronic, superficial or deep seated, transitory or constant. It can depend on functional or organic disorders of almost every organ in the body, abnormal blood conditions, toxic states, and more. Although headaches often accompany eye diseases and form a conspicuous symptom of eyestrain, their cause is rarely found in the eye. Certain forms are known by distinctive names such as hemicrania, migraine, megrim, or sick headache, which may be associated with ocular symptoms like pareses of extrinsic muscles or optic nerve affection. Facial neuralgia involves paroxysmal pain confined to areas supplied by the trigeminus nerve branches and is easy to recognize but requires further investigation for its cause. Eyestrain presents indefinite yet annoying symptoms such as headache, dizziness, sickness at the stomach, eye fatigue, grittiness, burning sensations, or transient blurring of vision. These symptoms may be due to refractive or muscular conditions of the eyes or other bodily issues.

Facial neuralgia, involving any or all branches of the trigeminus nerve, may be caused by catching cold, injury, general diseases, toxic conditions, eye affections, orbit issues, syphilis, malaria, chronic alcoholism, gout, diabetes, brain lesions, nasal problems, frontal sinus issues, middle ear infections, and herpes zoster. Yet in many ocular diseases, it forms a prominent symptom, potentially overshadowing other signs of trouble.

Eyestrain is characterized by symptoms such as headache, dizziness, sickness at the stomach, eye fatigue, grittiness, burning sensations, transient blurring of vision, and more. These may be due to refractive or muscular conditions of the eyes but can also originate from other bodily issues.

Key Takeaways
- Pain, while urgent and distressing, is an unreliable guide for diagnosis.
- Headaches can be caused by a wide range of conditions beyond the eye.
- Facial neuralgia requires thorough investigation to determine its cause.
Practical Tips
- Always test for tension in the eye when diagnosing facial neuralgia.
- Consider systemic causes before attributing symptoms solely to ocular issues.
Warnings & Risks
- Severe pain can overshadow other critical symptoms, leading to misdiagnosis.
- Facial neuralgia may be a symptom of deeper issues unrelated to the face.
Modern Application
While this chapter's diagnostic methods are outdated, understanding historical approaches provides valuable context for recognizing and addressing complex symptoms. Modern medical advancements have refined diagnosis techniques but the foundational importance of thorough investigation remains crucial.
