Loss of Vision	Partial or total vision loss	Severe	2, 4, 5

Table 1: Key Symptoms

Common Presentations

Eye injury symptoms often overlap, but certain signs are more indicative of serious trauma:

• Redness and Pain: Nearly all eye injuries present with some degree of redness and discomfort. Corneal abrasions, chemical injuries, and blunt trauma frequently cause acute pain 1, 2, 8.
• Tearing and Watering: The eye’s natural response to injury includes increased tear production—commonly seen in both minor and major injuries 2.
• Blurred or Reduced Vision: Any decrease in visual acuity should be taken seriously, as it often signals more severe underlying damage, such as open-globe injuries or retinal involvement 2, 4, 5.
• Photophobia: Sensitivity to light is commonly associated with corneal involvement, chemical injuries, or intraocular inflammation 1, 12.
• Swelling and Edema: Trauma may cause swelling of the eyelids or periorbital tissues, especially with blunt injuries 2.
• Foreign Body Sensation: A common complaint, especially with superficial injuries or corneal abrasions 2, 8.
• Loss of Vision: Sudden or progressive vision loss, particularly if accompanied by pain, is a red flag for serious injury such as globe rupture, retinal detachment, or optic neuropathy 2, 4, 5.

Symptom Progression

Not all symptoms appear immediately. For example, pain can be transiently enhanced after corneal abrasion, while dry eye symptoms may develop later as nerve endings recover or are altered 1.

When to Seek Help

• Any vision loss
• Persistent pain or redness
• Obvious eye deformity or bleeding
• Chemical exposure

Prompt evaluation by an eye care professional is critical to prevent permanent damage.

Types of Eye Injury

Eye injuries are diverse and can be classified based on the anatomical structures involved, the nature of the trauma, and the severity. Understanding these types helps guide appropriate management.

Type	Definition/Features	Risk Level	Source(s)
Open Globe	Full-thickness wound of the eye wall	High	2, 4, 5, 7
Closed Globe	Blunt force, eye wall remains intact	Moderate-High	4, 5, 7
Chemical Injury	Damage from acids, alkalis, or irritants	High	12, 14, 15
Burns	Thermal or electrical injury to ocular structures	High	2, 15
Corneal Abrasion	Superficial scratch of corneal epithelium	Low-Moderate	1, 8, 16
Hyphema	Blood in the anterior chamber	Moderate-High	2, 4, 10
Foreign Body	Object lodged superficially or intraocularly	Variable	5, 7, 11
Lid/Adnexal	Eyelid or surrounding tissue trauma	Low	2, 7

Table 2: Major Eye Injury Types

Open Globe Injuries

Open globe injuries are among the most severe, involving a full-thickness wound to the eye wall (cornea or sclera). They can result from sharp objects, explosions, or high-velocity trauma. These injuries carry a high risk of infection, retinal detachment, and permanent vision loss 2, 4, 5, 7.

Closed Globe Injuries

Closed globe (contusion) injuries occur when the eye wall remains intact despite significant blunt force. They can cause internal damage, such as hyphema (bleeding in the anterior chamber), lens dislocation, retinal edema, or even traumatic cataract 4, 5, 7.

Chemical and Thermal Burns

Chemical injuries, especially with alkali substances, can cause extensive and rapid damage to the ocular surface, potentially resulting in permanent visual impairment if not promptly treated. Thermal injuries (from fireworks, explosions, or hot objects) can similarly devastate ocular tissues 12, 14, 15.

Corneal Abrasion and Superficial Injuries

Corneal abrasions are among the most common eye injuries, often resulting from minor trauma, foreign bodies, or contact lens misuse. While painful, they usually heal well with appropriate care 1, 8, 16.

Hyphema

Hyphema—bleeding into the front chamber of the eye—is commonly caused by blunt trauma. It poses risks for increased intraocular pressure and secondary glaucoma 2, 4, 10.

Foreign Bodies

Foreign bodies may be superficial (on the conjunctiva or cornea) or intraocular (penetrating the eye). Intraocular foreign bodies significantly increase the risk of infection and vision loss 5, 7, 11.

Eyelid and Adnexal Injuries

These involve trauma to the eyelids or tissues around the eye. While less likely to threaten vision, they can be associated with deeper injuries 2, 7.

Causes of Eye Injury

Eye injuries have diverse causes, varying by age group, setting, and geography. Knowing the common causes can help with targeted prevention strategies.

Cause	Typical Scenario	Common Victims	Source(s)
Blunt Trauma	Falls, sports, accidents	Children, adults	4, 9, 10
Sharp Objects	Tools, glass, sticks	Children, workers	4, 6, 11
Explosions/Fireworks	Festivals, mishandling	Children, workers	2, 5, 6
Chemical Exposure	Industrial, household chemicals	Workers, children	12, 14, 15
Contact Lens	Improper use, hygiene issues	Contact lens users	3
Assault	Physical violence	Adults	3, 11
Sports Injuries	Balls, rackets, projectiles	Children, teens	3, 9, 10
Occupational	Industrial accidents	Workers	3, 11, 7

Table 3: Common Causes of Eye Injuries

Blunt and Sharp Trauma

• Blunt trauma is the leading cause of pediatric and adult eye injuries, often from sports, falls, or accidents at home or work 4, 9, 10.
• Sharp object injuries are frequent in both domestic and occupational settings. In children, scissors, toys, and tools are common culprits; in adults, workplace tools and glass are responsible 4, 6, 11.

Explosions and Fireworks

Firework-related injuries tend to spike during festivals and holidays. They are a serious concern for children and bystanders, with a higher risk of open-globe injuries and permanent vision loss 2, 5, 6.

Chemical and Burn Injuries

Chemical injuries, especially in industrial or household settings, can lead to rapid, severe ocular damage if not irrigated immediately. Alkali burns are particularly dangerous due to their deeper penetration 12, 14, 15.

Contact Lens and Iatrogenic Injuries

Improper use of contact lenses or complications during anesthesia and non-ocular surgeries can also result in eye injury, such as corneal abrasion 3, 8.

Assaults and Violence

A significant percentage of severe eye injuries in adults are due to assaults, including blunt trauma and penetrating wounds 3, 11.

Sports and Recreational Activities

Sports-related injuries are prevalent, especially among children and adolescents. They account for a large share of nonpenetrating injuries and are often preventable with the use of protective eyewear 3, 9, 10.

Occupational Injuries

The workplace remains a high-risk setting for eye injuries, especially in industrial jobs involving hazardous materials or machinery. Use of safety goggles is still inadequate in many cases 3, 7, 11.

Treatment of Eye Injury

Timely and appropriate treatment can mean the difference between full recovery and permanent vision loss. Management strategies depend on the type and severity of injury but generally follow key principles.

Treatment	Purpose/Approach	Indication	Source(s)
Irrigation	Remove chemicals/foreign substances	Chemical, burns	12, 14, 15
Surgical Repair	Restore anatomical integrity	Open globe, severe	2, 5, 7, 14
Protective Shield	Prevent further trauma	All severe injuries	16
Medications	Control pain/inflammation, prevent infection	Most injuries	1, 16
Amniotic Membrane	Promote healing, reduce scarring	Chemical, burns	14, 16
Blood-Based Therapies	Enhance healing	Recalcitrant cases	16
Bandage Contact Lens	Protect cornea	Abrasions, burns	16
Limbal Stem Cell Transplant	Restore surface integrity	Severe burns	12, 16

Table 4: Main Treatment Approaches

Immediate First Aid

• Chemical Injuries: Immediate and copious irrigation with saline or clean water is critical. Delays can worsen prognosis 12, 14, 15.
• Penetrating/Severe Blunt Injuries: Apply a protective shield (not pressure patch) and seek urgent ophthalmic care 16.
• Foreign Bodies: Do not attempt to remove deeply embedded objects. Seek medical attention.

Medical Management

• Pain and Inflammation: Cycloplegic agents (atropine, cyclopentolate) provide comfort. Steroidal and non-steroidal anti-inflammatory drugs are used judiciously to control inflammation, with careful monitoring for side effects 1, 16.
• Antibiotics: Used to prevent or treat secondary infection, especially in open-globe injuries or when foreign bodies are involved 16.
• Amniotic Membrane Therapies: These promote rapid healing and reduce scarring, especially after chemical injuries or severe burns 14, 16.
• Blood-based Therapies: Autologous serum tears or plasma-enriched drops can be helpful in stubborn cases 16.

Surgical Interventions

• Primary Repair: Open-globe injuries require surgical closure to restore globe integrity and prevent infection or extrusion of ocular contents 2, 5, 7, 14.
• Limbal Stem Cell Transplantation: For severe chemical burns with limbal stem cell loss, transplantation helps restore the ocular surface 12, 16.
• Amniotic Membrane or Tissue Grafts: Used when conventional healing is insufficient or for severe ocular surface reconstruction 14, 16.

Advanced and Supportive Therapies

• Bandage Contact Lenses: Serve to protect the healing cornea in abrasions and burns 16.
• Glue Therapies: Biologic or synthetic glues can be used in cases of corneal perforation risk 16.
• Neurotrophic Agents: In cases of severe nerve damage or persistent defects, topical nerve growth factors or insulin may aid recovery 1, 16.

Innovations in Drug Delivery

Recent advances include minimally invasive drug delivery systems such as microneedle-equipped eye patches that offer sustained and controlled medication release for optimal healing 13.

Rehabilitation and Follow-Up

Visual rehabilitation may involve additional surgeries (e.g., cataract extraction, retinal repair), optical correction, and long-term monitoring for complications like glaucoma or retinal detachment 4, 5, 12.

Conclusion

Eye injuries are complex, varied, and can have serious consequences if not managed promptly and properly. Understanding the key symptoms, injury types, causes, and evolving treatment options can empower individuals and healthcare professionals to act swiftly and effectively.

Key Takeaways:

• Eye injuries can present with pain, redness, tearing, blurred vision, and even vision loss; prompt recognition is vital 1, 2, 4, 5.
• Major types include open and closed globe injuries, chemical/thermal burns, corneal abrasions, hyphema, and foreign bodies 2, 4, 5, 7, 12.
• Common causes span blunt and sharp trauma, fireworks, chemicals, sports, workplace accidents, and assaults 3, 4, 5, 6, 9, 11.
• Immediate irrigation, protective measures, and timely medical or surgical intervention are key to preserving vision 12, 14, 16.
• Advanced therapies such as amniotic membrane transplantation, limbal stem cell grafts, and novel drug delivery techniques are improving outcomes for severe eye injuries 12, 13, 14, 16.

By increasing awareness and implementing preventive strategies, many eye injuries—and their potentially devastating consequences—can be avoided. If an eye injury occurs, prompt action and professional care offer the best chance for recovery.
