EYE PAIN:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
The primary care specialist may want to treat cases of obvious conjunctivitis without a culture and sensitivity. However, a smear and culture is useful especially if
Neisseria
is suspected. A smear may also reveal eosinophils suggesting allergic conjunctivitis. The primary care specialist may also use fluorescein dye to diagnose a foreign body. Most primary care physicians feel competent to use tonometry to diagnose glaucoma and may feel competent to use a slit lamp. However, when there is any doubt about the diagnosis, the most cost-effective approach is to refer the patient to an ophthalmologist.

Eye pain:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient's eye pain doesn't result from a chemical burn, take a complete history. Have the patient describe the pain fully. Is it an ache or a sharp pain? How long does it last? Is it accompanied by burning, itching, or discharge? Find out when it began. Is it worse in the morning or late in the evening? Ask about recent trauma or surgery, especially if the patient complains of sudden, severe pain. Does he have headaches? If so, find out how often and at what time of day they occur.

Conjunctival injection:
History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
When you take the patient’s history, always ask if he has associated pain. If so, when did the pain begin, and where is it located? Is it constant or intermittent? Also, ask about itching, burning, photophobia, blurred vision, halo vision, excessive tearing, or a foreign body sensation in his eye. Does the patient have a history of eye disease or trauma? If he has suffered ocular trauma, avoid touching the affected eye. Test his visual acuity and intraocular pressure (IOP) only if his eyelids can be opened without applying pressure. Place a metal shield over the affected eye to protect it, if necessary.
If the patient’s condition permits, examine the affected eye. First, determine the location and severity of conjunctival injection. Is it circumcorneal or localized? Peripheral or diffuse? Note any conjunctival or lid edema, ocular deviation, conjunctival follicles, ptosis, or exophthalmos. Also note the type and amount of any discharge.
Test the patient’s visual acuity to establish a baseline. Note if the patient has had vision changes: Is his vision blurred or his visual acuity markedly decreased? Next, test pupillary reaction to light.
Perform IOP measurements. To gauge increased IOP without a tonometer, gently place your index finger over the closed eyelid; if the globe feels rock-hard, IOP is elevated.

Eye pain [Ophthalmalgia]:
History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
If the patient’s eye pain doesn’t result from a chemical burn or from acute angle-closure glaucoma, take a complete history. Have the patient describe the pain fully. Is it an ache or a sharp pain? How long does it last? Is it accompanied by burning, itching, or a discharge? Find out when it began. Is it worse in the morning or late in the evening? Ask about recent trauma or surgery, especially if the patient complains of severe pain that developed suddenly. Does he have headaches? If so, find out how often and at what time of day they occur.
During the physical examination, don’t manipulate the eye if you suspect trauma. Carefully assess the eyelids and conjunctivae for redness, inflammation, and swelling. Then examine the eyes for ptosis or exophthalmos. Finally, test visual acuity with and without correction, and assess extraocular movements. Characterize any discharge. (See Examining the external eye, page 322.)

Eye Pain:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
A foreign body sensation occurs with a foreign body, corneal abrasion, or keratoconjunctivitis sicca. Itching is associated with allergic and vernal conjunctivitis. Photophobia occurs with iritis and herpes simplex keratitis. Deep pain suggests acute glaucoma or posterior scleritis. Pain on eye movement is found with optic neuritis, sinusitis, and influenza.

Conjunctival injection:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
When you take the patient's history, always ask if he has associated pain. If so, when did the pain begin, and where is it located? Is it constant or intermittent? Also, ask about itching, burning, photophobia, blurred vision, halo vision, excessive tearing, or a foreign body sensation in his eye. Does the patient have a history of eye disease or trauma? If he has suffered ocular trauma, avoid touching the affected eye. Does he wear contact lenses? If so, ask how often they're removed or changed if they're disposable. Test his visual acuity and intraocular pressure (IOP) only if his eyelids can be opened without applying pressure. Place a metal shield over the affected eye to protect it if needed.
If the patient's condition permits, examine the affected eye. First, determine the location and severity of conjunctival injection. Is it circumcorneal or localized? Peripheral or diffuse? Note any conjunctival or lid edema, ocular deviation, conjunctival follicles, ptosis, or exophthalmos. Also note the type and amount of any discharge.
