Chemical Burns to the Eye - Vision-Threatening Emergency Management

Oct 10, 2026

A 35-year-old woman develops a vision-threatening ocular chemical burn after bleach splashes into her left eye. Despite immediate washing with tap water, she has gritty sensation, blepharospasm, and conjunctival erythema. Chemical burns from acids and alkalis differ in tissue injury depth, but management priorities remain the same: rapidly restore neutral ocular pH by copious irrigation, using continuous flushing when possible and rechecking pH after irrigation.

A 35-year-old,previously healthy woman comes to the emergency department due to eye injury.She was cleaning her bathroom with industrial-strength bleach 30 minutes ago when some of the chemical splashed into her left eye.The patient immediately washed the eye with tap water forseveral minutes.She now has a gritty sensation in the eye and difficulty opening it.Physical examination reveals blepharospasm andconjunctival erythema of the left eye.Urgent ophthalmology consultation is requested.Which of the following is the best immediate step inmanagement of this patient? ○ A.Application of cycloplegics for symptom relief○ B.Continuous irrigation with normal saline○ C.Instillation of prophylactic topical antibiotics○ D.Patch application to keep the eye closed○ E.Topical application of acetic acid Submit Settings This patient has a vision-threatening ocular chemical burn.Typical symptoms include eye pain,blepharospasm(eg,inability to open theeyelid),a gritty sensation,and eye erythema;severe cases may lead to ischemia of the conjunctiva,and the eye may appear white.As in otherparts of the body,chemical burns are categorized as follows: ·Acid burns:cause coagulation necrosis (eg,protein denaturation)that results in an eschar,thereby preventing further acid penetration andinjury ·Alkali burns(eg,bleach):cause liquefactive necrosis (eg,cell membrane dissolution),which leads to deeper penetration of tissues andtherefore more severe injuries In either case,the most important (and urgent)step in management is to restore a neutral pH by flushing the eye copiously with water or saline.Normalization of pH typically takes 30-60 minutes but may take greater than >2 hours for alkali burns.In ideal circumstances,a providercontinuously flushes the eye,but eye-wash devices(eg,Morgan lens)can be used.Topical anesthesia can be administered to improve patientcomfort and tolerance of irrigation.After cessation of irrigation,the eye's pH should be remeasured with litmus paper to confirm that it remainsneutral. (Choice A)Cycloplegics(parasympatholytic agents thatt prevent light-induced miosis)may be prescribed for long-term management of paincaused by photophobia resulting from large corneal abrasions.They are not indicated for acute ocular burns. eyelid),a gritty sensation,and eye erythema;severe cases may lead to ischemia of the conjunctiva,and the eye may appear white.As in otherparts of the body,chemical burns are categorized as follows: ·Acid burns:cause coagulation necrosis (eg,protein denaturation)that results in an eschar,thereby preventing further acid penetration andinjury ·Alkali burns(eg,bleach):cause liquefactive necrosis(eg,cell membrane dissolution),which leads to deeper penetration of tissues andtherefore more severe injuries In either case,the most important (and urgent)step in management is to restore a neutral pH by flushing the eye copiously with water or saline.Normalization of pH typically takes 30-60 minutes but may take greater than>2 hours for alkali burns.In ideal circumstances,a providercontinuously flushes the eye,but eye-wash devices (eg,Morgan lens)can be used.Topical anesthesia can be administered to improve patientcomfort and tolerance of irrigation.After cessation of irrigation,the eye's pH should be remeasured with litmus paper to confirm that it remainsneutral.

(Choice C)Topical antibiotics may be used in the management of ocular chemical burns but not before normalization of the eye's pH is achievedthrough copious irrigation. (Choice D)Eye patch application was once a commonly used treatment for corneal abrasions because it was thought to promote epithelialproliferation and encourage healing.It is used much less frequently now because it does not seem to

FAQs

What is the best immediate step for an ocular chemical burn?

Restore a neutral ocular pH by flushing the eye copiously with water or saline as the most urgent step.

How do acid and alkali chemical burns differ in injury pattern?

Acids cause coagulation necrosis with eschar formation that limits penetration, while alkalis cause liquefactive necrosis leading to deeper tissue penetration and more severe injury.

When should pH be rechecked after irrigation?

After cessation of irrigation, the eye’s pH should be remeasured with litmus paper to confirm it remains neutral.
