Alkaline injuries to the eye are among the most severe ocular emergencies, requiring swift and effective intervention to minimize damage and preserve vision. Alkaline burns pose a significant risk due to their ability to deeply penetrate eye tissues, causing long-term complications. Here’s a guide on what to do in an emergency involving alkaline substances; however, it’s always crucial to see an eye doctor or medical professional as soon as possible after completing the initial eye flushing.
What to Do Immediately After Alkaline Contact with the Eye
Steps for Effective Eye Washing
- Begin irrigation immediately, using any clean liquid such as tap water, saline, or an isotonic solution. Don’t wait for a specific solution—act with what’s available.
- Continue flushing the affected eye for at least 20 to 30 minutes to dilute and remove the alkaline substance.
- Position the head upright and tilted toward the affected side, allowing the liquid to flow outward, away from the unaffected eye.
- Encourage the person to blink and move their eye in all directions during flushing to ensure all areas are irrigated.
- If the person wears contact lenses and they don’t come out naturally during irrigation, remove them gently after flushing has begun.
Common Mistakes to Avoid
- Do not delay irrigation while seeking medical attention—start flushing the eye immediately.
- Avoid attempting to neutralize the alkaline substance with acids or other chemicals, as this can worsen the injury.
- Do not prioritize transportation over on-site flushing—irrigation is the first and most critical step.
- Never stop irrigation prematurely to remove contact lenses; continue flushing while carefully removing them later.

Why Immediate Action Is Critical for Alkaline Eye Injuries
The Danger of Alkaline Eye Burns
Alkali ocular injuries are a significant concern due to their potential to cause severe damage to the eye. A study in Martinique found that 50% of these injuries were mild, 31% were moderate, and 19% were severe. In Australia, another study showed that 75% of alkali eye injuries were mild.
These findings suggest that while a significant proportion of alkali eye injuries are mild, a notable percentage are moderate to severe, underscoring the importance of quick and thorough washing or irrigation of the eye and seeing an eye doctor as soon as eye washing is done.
Alkaline burns are among the most severe chemical injuries to the eye due to their ability to penetrate tissues quickly, causing liquefative necrosis and extensive tissue destruction. These injuries can result in:
Why Alkaline Burns Are Especially Severe
How Alkali Burns Cause Damage
Alkaline substances, commonly found in household and industrial products, are lipophilic, meaning they dissolve fats, allowing them to:
- Penetrate cell membranes deeply, causing extensive damage.
- Break down fatty acids through saponification, enabling them to invade ocular tissues.
- Trigger ongoing tissue destruction by releasing proteolytic enzymes that worsen the injury over time.
- Sustain damage long after exposure, making immediate irrigation critical to halt progression.
Common Alkali Agents and Their Effects
Ammonia: Considered the most dangerous alkali chemical with regards to ocular burns, causing severe damage within 3 minutes.
Common examples of ammonia-based products include: Drain Cleaners
A study on U.S. poison control data identified these frequent sources of moderate to severe alkali injuries:
Both home and workplace environments pose significant risks, highlighting the need for prevention.
How Alkali Burns Compare to Acid Burns
- Alkaline Burns: Cause deeper tissue damage and are more likely to result in severe complications, including vision loss.
- Acidic Burns: Typically cause surface-level damage by coagulating proteins, which can form a barrier to deeper penetration. However, exceptions like hydrofluoric acid can mimic alkali burns.
The distinct nature of alkali burns underscores the importance of immediate intervention.
Preventing Alkaline Eye Injuries
Safety Tips for Handling Alkalis
- Always wear protective eyewear when using products with alkali ingredients.
- Keep hazardous chemicals securely stored, out of reach of children.
- Follow label instructions for safe use and disposal.
Emergency Preparedness
- Have an eye wash station or saline solution easily accessible at home or work.
- Educate yourself and others about the importance of immediate eye flushing after exposure.
Proactive steps can prevent serious injuries, and knowing how to respond quickly in emergencies is crucial to protecting eye health.
Symptoms and Early Signs of Alkali Eye Burns
Common Symptoms to Watch For
Recognizing the symptoms early can significantly positively impact the outcome for an alkali eye burn. Typical symptoms may include:
These symptoms often appear quickly and may escalate, but they don’t always correlate with the injury’s severity. It’s crucial to act swiftly and not delay treatment based solely on the presence or absence of these symptoms.
Why Pain Intensity May Not Reflect Damage
One of the challenging aspects of managing alkali eye burns is that nerve damage often occurs with these injuries, meaning severe damage can occur without corresponding pain. Alkali substances, such as those found in oven or drain cleaners, penetrate the eye tissue rapidly and can cause extensive harm without significant immediate discomfort. This rapid penetration allows hydroxyl ions to denature collagen in the cornea, exacerbating tissue damage without correlating pain levels. Hence, a lack of severe pain does not mean a lack of severe injury.

Management of Alkaline Eye Injuries
Standard Treatments and Medications for Alkaline Eye Injuries
Alkaline eye injuries require immediate attention to prevent severe damage and preserve vision. Here’s how these injuries are typically managed:
- Immediate Irrigation: The first and most crucial step is immediate and thorough flushing of the eye to remove the alkaline substance and minimize tissue damage.
- Antibiotics: To prevent infection, patients are prescribed topical antibiotic ointments such as erythromycin. In severe cases, stronger antibiotics like fluoroquinolones may be used.
- Artificial Tears: Preservative-free lubricating drops are essential to maintain comfort and moisture, aiding the healing process.
- Steroid Drops: In the initial phase, steroids like prednisolone are used cautiously to control inflammation and prevent further damage. Steroids are applied regularly during the first week and then tapered under medical supervision to avoid adverse effects.
- Cycloplegic Agents: These medications help alleviate pain by dilating the pupil and reducing muscle spasms in the eye.
- Ascorbic Acid: Vitamin C is important for collagen synthesis and is administered orally and sometimes topically to support tissue repair and strengthen the cornea.
- Doxycycline: An oral medication with anti-inflammatory properties that can inhibit enzymes that break down corneal tissue. Caution is needed for children and pregnant women when using this medication.
Recommended Protocols Based on Severity of Alkaline Burns
Treatment strategies depend on the severity of the burn, categorized using the Roper-Hall classification:
- Grade I: Typically managed with lubricating drops, antibiotic ointments, and careful monitoring. The prognosis is excellent.
- Grade II: Involves more intensive use of steroids and antibiotics, oral vitamin C, doxycycline, and possible removal of damaged tissue (debridement). Follow-up care is crucial to monitor healing.
- Grade III: Similar to Grade II but may include procedures like amniotic membrane transplantation (AMT) for additional protection and to facilitate healing. Regular assessments ensure long-term safety and recovery.
- Grade IV: Requires significant surgical intervention due to extensive damage. Treatments may include tenonplasty, AMT, or stem cell transplantation. Long-term management is critical for preserving remaining vision and overall eye health.
Each case of alkaline eye injury is unique, demanding comprehensive evaluation and customized treatment plans.
Preventive Measures and Safety Protocols for Alkaline Eye Injuries
Importance of Personal Protective Equipment
Alkaline burns to the eye can be sudden, painful, and potentially devastating, especially when they involve alkaline substances found in many household and industrial cleaning products. These injuries often occur in the workplace and can be particularly severe due to the lipophilic nature of alkali agents, which rapidly penetrate eye tissues. To prevent such injuries, wearing appropriate personal protective equipment (PPE) is crucial. Safety goggles or face shields should be worn whenever you’re handling alkaline substances that pose a risk to your eyes. These protective measures are mandated in workplace settings where hazardous chemicals are used, as stipulated by the Occupational Safety and Health Administration (OSHA). However, even the best equipment may not fully protect against high-pressure alkaline splashes, highlighting the need for comprehensive safety protocols.
Safe Storage of Alkaline Materials
Storing alkaline materials safely is as vital as using protective gear when handling them. Most alkaline eye injuries at home are preventable with correct storage practices. Household items like drain cleaners, ammonia, and oven cleaners—which often contain strong alkalis—should be kept out of reach of children to prevent accidental exposure. Proper labeling is equally important, ensuring that all family members are aware of the substances and their potential dangers. For both industrial and home settings, alkaline chemicals should be stored in a cool, dry place, ideally in a cabinet with restricted access. Clear labeling and easy-to-read hazard warnings can help individuals understand the risks involved with each alkaline substance, fostering a safer environment.
Planning and Emergency Preparedness for Alkaline Exposures at Home and Work
A critical component of minimizing the impact of alkaline eye injuries is effective planning and emergency preparedness, both at home and work. Developing a plan for immediate response to alkaline chemical exposure can significantly reduce injury severity. This could include having eye wash stations or access to clean water readily available and ensuring all individuals understand how to respond to an alkaline eye emergency. At work, regular safety drills and the installation of easily accessible eye wash stations can help ensure rapid intervention. At home, it is beneficial to have an action plan that includes flushing the eyes with water immediately in case of exposure and knowing the quickest route to an emergency department. Being prepared with the right knowledge and resources can greatly improve the response to alkaline exposures and prevent long-term damage.
