Bacterial Conjunctivitis

Bacterial conjunctivitis, commonly known as “pink eye,” is an inflammation of the transparent membrane (conjunctiva) that lines the white part of the eye and the inner surface of the eyelids. In this condition, bacteria invade the conjunctival tissues, triggering an immune response that leads to redness, swelling, and discharge. Unlike viral conjunctivitis, which often produces a watery discharge, bacterial conjunctivitis typically yields a thicker, purulent (pus-like) secretion. Prompt recognition and appropriate treatment are essential, as untreated bacterial conjunctivitis can lead to discomfort, spread to others, and, in rare cases, serious corneal complications.

Bacterial conjunctivitis arises when pathogenic bacteria—most commonly Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, or Neisseria gonorrhoeae—colonize or infect the conjunctival surface. The bacteria multiply on the conjunctiva, releasing toxins and triggering an inflammatory response. Immune cells migrate into the tissue, causing blood vessels to dilate (red eye), epithelial cells to swell (chemosis), and goblet cells to produce excess mucus and pus. While uncomfortable, bacterial conjunctivitis is rarely sight-threatening when treated timely.

Types of Bacterial Conjunctivitis

1. Hyperacute Bacterial Conjunctivitis

Hyperacute bacterial conjunctivitis develops rapidly—often within hours—and is characterized by intense redness, severe swelling, and a profuse, thick, greenish discharge. It is most commonly caused by Neisseria gonorrhoeae. Without immediate antibiotic therapy, hyperacute conjunctivitis can rapidly invade the cornea, leading to ulceration and scarring.

2. Acute Bacterial Conjunctivitis

Acute bacterial conjunctivitis is the most frequent form. Symptoms evolve over one to three days and include redness, a yellow or white purulent discharge, and eyelid crusting. Typical pathogens include Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. This form often resolves within one to two weeks, especially with topical antibiotic treatment.

3. Chronic Bacterial Conjunctivitis

Chronic bacterial conjunctivitis persists for more than four weeks and may wax and wane. It often stems from underlying eyelid or tear-drainage abnormalities, chronic blepharitis, or repeated inadequate antibiotic courses, allowing bacteria such as Moraxella or atypical mycobacteria to flourish. Patients experience mild, persistent redness, intermittent discharge, and foreign-body sensation.

Causes of Bacterial Conjunctivitis

1. Direct Bacterial Infection
   Bacteria gain direct entry into the conjunctival sac, often via contaminated hands, towels, or cosmetics. Pathogens multiply on the moist conjunctival surface, producing toxins that damage epithelial cells and trigger inflammation.

2. Spread from Upper Respiratory Infection
   Bacteria from sinusitis, otitis media, or common colds can travel through the nasolacrimal duct into the conjunctiva, leading to secondary conjunctivitis.

3. Contact Lens Use
   Improper lens hygiene—such as extended wear, inadequate cleaning solutions, or swimming with lenses—can introduce bacteria onto the eye, resulting in conjunctival infection.

4. Trauma or Foreign Body
   Scratches, abrasions, or foreign materials (e.g., dust, metal shards) disrupt the conjunctival barrier, allowing bacteria to infiltrate and cause localized infection.

5. Eyelid Margin Disease (Blepharitis)
   Chronic inflammation of the eyelid margins encourages bacterial overgrowth, which can spread to the conjunctiva, producing conjunctival redness and discharge.

6. Blocked Tear Drainage (Nasolacrimal Duct Obstruction)
   Obstruction in tear drainage leads to tear stagnation, which fosters bacterial growth and retrograde infection of the conjunctiva.

7. Ocular Surgery or Procedures
   Postoperative contamination—during cataract surgery, Lasik, or intravitreal injections—can introduce bacteria to the eye, resulting in conjunctival infection.

8. Neonatal Exposure During Birth
   Newborns passing through an infected birth canal may acquire Neisseria gonorrhoeae or Chlamydia trachomatis, causing hyperacute or inclusion conjunctivitis, respectively.

9. Immunosuppression
   Conditions such as HIV/AIDS or immunosuppressive therapy reduce the body’s ability to control bacterial colonization, increasing risk of conjunctival infection.

10. Poor Hygiene Practices
    Sharing towels, pillows, or eye makeup spreads bacteria among individuals, facilitating outbreaks in families, schools, or dormitories.

11. Environmental Irritants
    Airborne pollutants—smoke, chemical fumes, dust—can irritate the conjunctiva, compromising its defenses and allowing bacteria to invade.

12. Allergic Conjunctivitis with Secondary Infection
    Severe allergic inflammation damages the conjunctival epithelium, creating entry points for opportunistic bacteria.

13. Exposure to Contaminated Water
    Swimming or bathing in polluted pools, hot tubs, or natural bodies of water exposes the eye to diverse bacteria capable of causing conjunctivitis.

14. Chronic Systemic Diseases
    Conditions such as diabetes mellitus impair immune response and wound healing, predisposing to recurrent or persistent conjunctival infections.

15. Hospital-Acquired Infections
    Patients in intensive care units or with indwelling devices (e.g., ventilators) may experience healthcare-associated bacterial conjunctivitis due to resistant organisms.

Symptoms of Bacterial Conjunctivitis

1. Eye Redness (Hyperemia)
   Dilated blood vessels in the conjunctiva cause a pink or deep-red appearance, often described as “bloodshot” eyes.

2. Purulent Discharge
   Thick yellow, green, or white pus accumulates, especially after sleep, leading to eyelid crusting and matting.

3. Eyelid Swelling (Edema)
   Inflammation of the conjunctiva and eyelid margins results in puffiness, making it difficult to fully open the eye.

4. Burning or Stinging Sensation
   Toxin-induced irritation of the conjunctival nerves creates a constant sensation of burning, akin to acid on the eye.

5. Itching
   Mild to moderate itching arises from inflammatory mediators, though itching is often more prominent in allergic conjunctivitis.

6. Foreign-Body Sensation
   Patients frequently describe a gritty feeling, as though sand or a small object is trapped under the eyelid.

7. Tearing (Epiphora)
   Excess tearing occurs as the lacrimal glands produce additional fluid to flush out bacteria and debris.

8. Photophobia (Light Sensitivity)
   Inflammation of the conjunctiva can extend to the cornea, causing discomfort in bright light.

9. Blurred Vision
   Purulent discharge and tear film instability temporarily reduce visual clarity; vision typically returns once secretions are cleared.

10. Crusting of Eyelashes
    Overnight accumulation of discharge cements eyelashes together, often requiring gentle cleaning in the morning.

Diagnostic Tests for Bacterial Conjunctivitis

Physical Examination

1. External Eye Inspection
   The clinician observes eyelid position, conjunctival redness, and swelling. Abnormal findings—such as asymmetry, chemosis (conjunctival swelling), or pseudomembranes—guide further testing.

2. Visual Acuity Test
   Measuring visual sharpness with a Snellen chart assesses whether the infection has impacted vision. A sudden drop may suggest corneal involvement.

3. Pupillary Reaction Assessment
   Evaluating pupil size and response to light helps rule out intraocular inflammation (iritis) or neurologic causes of red eye.

4. Slit-Lamp Examination
   A magnified, illuminated microscope (slit lamp) allows detailed inspection of the conjunctiva, cornea, anterior chamber, and lids, identifying discharge, epithelial defects, or early corneal ulcers.

5. Fluorescein Staining
   Applying fluorescein dye reveals epithelial defects on the cornea or conjunctiva under cobalt-blue light, highlighting abrasions or ulcers that may accompany infection.

Manual Tests

6. Eyelid Eversion
   Manually flipping the upper eyelid exposes the tarsal conjunctiva, allowing detection of follicles, papillae, or retained foreign bodies lodged in the fornix.

7. Conjunctival Blanching Test
   Gentle pressure from a cotton-tipped applicator temporarily compresses conjunctival vessels; rapid return of redness confirms vascular integrity and distinguishes from deeper inflammation.

8. Lymph Node Palpation
   Palpating preauricular and submandibular lymph nodes checks for tenderness or enlargement, indicating regional immune activation common in bacterial and viral conjunctivitis.

9. Punctal Occlusion Test
   Manually occluding the lacrimal puncta assesses tear drainage efficiency; poor drainage suggests risk for chronic infection due to tear stasis.

Laboratory and Pathological Tests

10. Gram Staining
    A direct smear of conjunctival discharge is stained and examined microscopically to visualize bacteria’s shape and Gram reaction (positive or negative), guiding empirical therapy.

11. Culture and Sensitivity
    Conjunctival swabs are inoculated onto bacterial culture media; isolated pathogens undergo antibiotic susceptibility testing to identify the most effective drug.

12. Polymerase Chain Reaction (PCR)
    Highly sensitive nucleic acid amplification detects specific bacterial DNA—useful for fastidious organisms like Chlamydia trachomatis.

13. Enzyme-Linked Immunosorbent Assay (ELISA)
    Detects bacterial toxins or antigens in tear fluid, providing rapid confirmation of certain pathogens.

14. Complete Blood Count (CBC)
    Elevated white blood cell count supports systemic bacterial infection; a left shift (increased immature neutrophils) indicates acute bacterial response.

15. C-Reactive Protein (CRP) Level
    Elevated CRP, an acute-phase reactant, corroborates inflammatory activity and helps differentiate bacterial from viral or allergic conjunctivitis.

16. Procalcitonin Test
    Higher procalcitonin levels are more specific for bacterial infections versus viral causes, aiding diagnostic clarity.

Electrodiagnostic Tests

17. Ocular Surface Potential Difference (OSPD)
    Measures electrical potential across the conjunctival epithelium; altered values indicate epithelial damage and inflammation severity.

18. Electro-oculography (EOG)
    Records corneo-retinal standing potential; while primarily used for retinal disorders, EOG can detect subtle ocular surface changes in severe conjunctival inflammation.

19. Tear Film Interferometry
    Assesses tear film stability by measuring interference patterns; unstable or disrupted tear films often accompany conjunctival infections.

Imaging Tests

20. Slit-Lamp Photography
    High-resolution images document conjunctival vascular changes, chemosis, and discharge distribution for monitoring treatment response over time.

21. Anterior Segment Optical Coherence Tomography (AS-OCT)
    Noninvasive, cross-sectional imaging visualizes conjunctival thickness, subepithelial fluid, and early membrane formation, aiding diagnosis of severe or chronic cases.
