Dendritic Keratitis: Signs, Causes and Treatment
Dendritic keratitis is a viral infection that affects the cornea, the clear front part of the eye. This condition is commonly caused by the herpes simplex virus, the same virus responsible for cold sores. When the virus infects the cornea, it can lead to the formation of branching ulcerations called dendrites, hence the name "dendritic keratitis."
The virus can lie dormant in the body and reactivate during times of stress or illness, leading to the development of this eye condition. It is essential to seek medical attention if you suspect you have dendritic keratitis to prevent potential complications and protect your vision.
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 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.

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 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.
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
Risk Factors
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.

Book an AppointmentDiagnosis 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.
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.
Frequently Asked Questions
How can dendritic keratitis be identified through its signs?
Dendritic keratitis can be identified by its characteristic branching ulcer on the cornea, typically with accompanying eye pain and redness.
What are the recommended do's and don'ts for managing dendritic keratitis?
Do seek prompt medical attention. Don't wear contact lenses until cleared by a doctor. Avoid touching or rubbing your eyes to prevent further.
Are there any risks associated with untreated dendritic keratitis?
Yes, untreated dendritic keratitis can lead to vision loss and corneal scarring. It is important to seek timely medical treatment for this condition.
