Conjunctival Keratotic Plaques

Conjunctival keratotic plaques—commonly known as Bitot’s spots—are superficial accumulations of keratinized epithelial cells on the bulbar conjunctiva that appear as triangular, oval, or irregular, foamy, whitish patches just outside the corneal edge WikipediaAll About Vision. These lesions result from metaplastic transformation of conjunctival epithelium and impaired mucin secretion, leading to surface dryness and keratin build‑up that often harbors gas‑forming bacteria like Corynebacterium xerosis EyeWiki.

Conjunctival keratotic plaques, commonly known as Bitot’s spots, are triangular or irregular foamy-white patches that form on the bulbar conjunctiva—most often temporally, near the limbus. Histologically, these lesions consist of keratinized epithelial cells, fatty debris, and corynebacterial colonies embedded in an edematous stroma. They arise when chronic vitamin A deficiency induces squamous metaplasia of mucin-secreting goblet cells, preventing adequate tear film and mucin production, and leading to local xerosis and keratin buildup on the ocular surface CDC Stacks.

Vitamin A is essential for maintaining the specialized, non-keratinized epithelium of the conjunctiva and cornea. In deficiency states, retinol-dependent pathways fail to support normal epithelial turnover, prompting metaplastic transformation and inadequate mucin secretion. The resulting keratotic plaque not only signals systemic malnutrition but also predisposes to secondary infection, progressive xerosis, and, if untreated, corneal ulceration or keratomalacia AAOAll About Vision.

Types

1. Classic Nutritional Keratotic Plaque
   The prototypical Bitot’s spot arises from dietary vitamin A deficiency, which disrupts goblet cell function and mucin production, causing conjunctival dryness and keratinization WikipediaWikipedia.

2. Infectious Keratotic Plaque
   In some cases, keratinized cells mix with gas‑forming bacteria (notably Corynebacterium xerosis), producing the characteristic foamy surface overlying the keratin accumulation EyeWiki.

3. Environmental Keratotic Plaque
   Prolonged exposure of the exposed bulbar conjunctiva to UV light, wind, dust, or smoke can provoke keratin deposition even in the absence of frank vitamin A deficiency All About Vision.

4. Drug‑Induced Keratotic Plaque
   Certain medications—especially bile acid sequestrants like colestyramine—impair fat‑soluble vitamin absorption and may precipitate Bitot‑like spots by reducing vitamin A uptake Wikipedia.

What to Do & What to Avoid

Do:

• Maintain a diet rich in vitamin A (leafy greens, liver, dairy).

• Practice blinking and palming exercises daily.

• Use prescribed ocular lubricants as directed.

• Attend regular follow‑up visits.

• Protect eyes from wind, dust, and UV exposure.

Avoid:

• Rubbing or scratching the eyes.

• Prolonged screen time without breaks.

• Smoking and secondhand smoke exposure.

• Environments with excessive dust or pollutants.

• Overuse of topical steroids without supervision.

Frequently Asked Questions

1. What causes conjunctival keratotic plaques?
   Chronic vitamin A deficiency leads to squamous metaplasia of conjunctival epithelium, blocking mucin secretion and causing keratin buildup.

2. Can Bitot’s spots be reversed?
   Yes—early lesions often resolve within weeks of vitamin A repletion and ocular lubricants.

3. Are these plaques contagious?
   No, they result from nutritional deficiency and epithelial change, not infection.

5. How long does treatment take?
   Systemic vitamin A correction can show improvement in 2–4 weeks; complete resolution may take several months.

6. Can children get these plaques?
   Yes—young children in areas with poor nutrition are especially at risk.

7. Is surgery always needed?
   No—most cases respond to nutritional and ocular surface therapies unless lesions are fibrotic.

8. Will vision be affected?
   Isolated plaques rarely impair vision, but progression to keratomalacia can threaten sight.
