Dendritic Keratitis: Signs, Causes and Treatment

Written by Medicover Team and Medically Reviewed by Dr Manaswini Priya Varanasi , Ophthalmologists



Dendritic keratitis is a viral infection of the cornea most commonly caused by the herpes simplex virus (HSV). It leads to characteristic branching ulcers on the cornea and can cause eye pain, redness, blurred vision, tearing, and sensitivity to light.


What Are the Symptoms of Dendritic Keratitis?

Dendritic keratitis, a viral infection of the eye caused by the herpes simplex virus, can present with symptoms such as eye pain, redness, light sensitivity, and blurry vision. Patients may also experience a sensation of something in the eye and excessive tearing.

If left untreated, dendritic keratitis can lead to corneal scarring and vision problems. It is essential to seek prompt medical attention if you suspect you have symptoms of dendritic keratitis to prevent complications and receive appropriate treatment.

  • Eye redness and irritation are common symptoms of dendritic keratitis, often accompanied by sensitivity to light.
  • Patients may experience blurred vision, especially in the affected eye, due to the corneal damage caused by the virus.
  • Foreign body sensation or a gritty feeling in the eye can be a presenting complaint in individuals with dendritic keratitis.
  • Excessive tearing or watery eyes may occur as a result of the eye's natural response to the viral infection.
  • Some individuals with dendritic keratitis report experiencing pain or discomfort in the affected eye, varying in intensity.

What are the Causes of Dendritic Keratitis?

This viral infection can occur due to a compromised immune system, previous exposure to the virus, or contact with contaminated ocular fluids. Factors like stress, fatigue, and UV exposure can trigger HSV reactivation, leading to dendritic keratitis.

Additionally, poor hygiene practices, such as sharing towels or eye makeup, can facilitate the transmission of the virus. Prompt diagnosis and treatment are crucial in managing dendritic keratitis to prevent complications and preserve ocular health.

  • Infection with the herpes simplex virus is a common cause of dendritic keratitis, leading to corneal inflammation and potential vision impairment.
  • Exposure to ultraviolet (UV) light can trigger dendritic keratitis in individuals with a history of eye sensitivity to sunlight.
  • Certain autoimmune conditions, such as rheumatoid arthritis or lupus, may increase the risk of developing dendritic keratitis.
  • Extended contact lens wear without proper hygiene practices can introduce pathogens to the eye, contributing to dendritic keratitis development.
  • Environmental factors like dry or dusty conditions can irritate the cornea, making it more susceptible to dendritic keratitis infections.

When Should You See a Doctor for Dendritic Keratitis?

Immediate consultation with an ophthalmologist or eye specialist is important to prevent corneal damage and vision complications.

  • Persistent eye pain or redness
  • Sudden blurred vision
  • Increased sensitivity to light
  • Excessive tearing or eye discharge
  • Feeling like something is stuck in the eye

What are the Types Of Dendritic Keratitis?

Dendritic keratitis, a type of corneal infection caused by the herpes simplex virus, presents in various forms based on its severity and clinical presentation. The types of dendritic keratitis include typical dendritic ulcers characterized by branching lesions on the cornea, geographic ulcers with irregular borders, and pseudo-dendrites that resemble the typical pattern but lack true branching.

These variations in dendritic keratitis help ophthalmologists determine the appropriate treatment and management strategies for each patient, aiming to prevent complications and preserve vision.

  • Dendritic keratitis is a type of corneal infection caused by the herpes simplex virus.
  • The two main types of dendritic keratitis are epithelial and stromal.
  • Epithelial dendritic keratitis affects the outer layer of the cornea and presents as branching ulcers.
  • Stromal dendritic keratitis involves deeper layers of the cornea and can lead to scarring.
  • Both types of dendritic keratitis can cause pain, redness, blurred vision, and light sensitivity.
  • Proper diagnosis and prompt treatment are essential to prevent complications and preserve vision.
  • Treatment may include antiviral medications, corticosteroids, and lubricating eye drops.
  • In severe cases, surgical intervention may be necessary

What are the Risk Factors of Dendritic Keratitis?

Dendritic keratitis, a viral infection of the cornea typically caused by herpes simplex virus, can be influenced by various risk factors. People with a history of cold sores or ocular herpes are at a higher risk of developing dendritic keratitis.

Other factors include a weakened immune system, use of contact lenses, eye trauma, and prolonged sun exposure. Additionally, stress and fatigue can also increase susceptibility to this condition. Understanding these risk factors can help individuals take preventive measures to reduce the likelihood of developing dendritic keratitis.

  • Contact lens wear, especially improper hygiene or extended wear, increases the risk of dendritic keratitis.
  • Previous history of herpes simplex virus (HSV) infection, particularly ocular herpes, is a significant risk factor for dendritic keratitis.
  • Immunosuppression, such as from medications or underlying conditions, predisposes individuals to developing dendritic keratitis.
  • Eye trauma or injury, including scratches or abrasions to the cornea, can increase the likelihood of dendritic keratitis.
  • Ultraviolet (UV) light exposure, without proper eye protection, is a potential risk factor for the development of dendritic keratitis.

How is the diagnosis of Dendritic Keratitis?

This may involve using a slit lamp to inspect the cornea for characteristic branching lesions. To confirm the diagnosis, a fluorescein dye test can be performed, where the dye highlights any erosions on the cornea caused by the herpes simplex virus.

Additionally, collecting a sample of the eye's surface cells for microscopic analysis can help identify the presence of viral particles. These various methods collectively contribute to a thorough diagnostic process for dendritic keratitis.

  • Diagnosis of dendritic keratitis typically involves a thorough eye examination by an ophthalmologist.
  • Fluorescein staining may be used to visualize the characteristic dendritic pattern on the cornea.
  • In some cases, a scraping of the corneal lesion for laboratory testing, such as viral culture or polymerase chain reaction (PCR), may be necessary.
  • Visual acuity testing and assessment of symptoms help in confirming the diagnosis of dendritic keratitis.
  • Slit-lamp examination aids in the detailed evaluation of the corneal lesions and associated eye structures.

What is the Treatment for Dendritic Keratitis?

Dendritic keratitis, a viral infection affecting the cornea, can be effectively treated through various approaches. Antiviral eye drops or ointments are commonly prescribed to combat the herpes simplex virus responsible for this condition. In some cases, oral antiviral medications may be recommended for systemic treatment.

Additionally, supportive measures such as lubricating eye drops can help alleviate symptoms and promote healing. In severe or recurrent cases, a healthcare provider might consider procedures like corneal debridement or even a corneal transplant. Early detection and prompt treatment are crucial in managing dendritic keratitis to prevent complications and preserve vision.
