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.

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.
