What is a Pseudodendrite?

What is a Pseudodendrite?

There are many other “dendritic” lesions of the corneal epithelium that are not due to HSV and have been referred to as “pseudodendrites.” It is very common to see patients with healing epithelial defects or neurotrophic epitheliopathy present with a “dendrite” or a branching epithelial lesion.

What is Pseudodendritic keratitis?

Pseudodendritic keratitis was defined as raised, branching, epithelial lesions with/or without associated punctate epithelial staining.

What causes corneal dendrites?

cause. In dendritic (branching) keratitis, or dendritic ulcer, the cornea is inflamed by infection with the herpes simplex (cold sore) virus or herpes zoster (shingles) virus. The lesions, as the name suggests, follow branching lines, along which minute blisters may form and break, leaving raw areas.

How do you treat Pseudodendrites?

Conclusions: Topical 0.15% ganciclovir gel, 5 times a day until pseudodendritic lesion healing and tapering to bid for 2 to 4 weeks thereafter, is an effective treatment for pseudodendrites in HZO-affected cases that are often a challenge to manage with other oral or topical antivirals.

What is Ramsay Hunt Syndrome?

Ramsay Hunt syndrome is a painful rash around the ear, on the face, or on the mouth. It occurs when the varicella-zoster virus infects a nerve in the head.

What is Hutchinson’s?

Hutchinson’s sign is a herpes zoster vesicle present on the tip or side of the nose. 1. It reflects zoster involvement of the 1st branch of the trigeminal nerve, and is concerning for herpes zoster ophthalmicus. 1. Herpes zoster vesicles may present as papular lesions or macular vesicles on an erythematous base.

What is radial Keratoneuritis?

BACKGROUND: Radial keratoneuritis is an inflammatory response of the corneal nerves associated with a perineural infiltrative process. Clinically it appears as thickened corneal nerves with ragged borders located in the anterior or mid-stroma and distributed in a linear radial pattern.

What is a dendritic eye ulcer?

In some people the virus becomes active again and travels along the nerve until it finds a way out, either on the surface of the skin causing a cold sore or the eye causing an ulcer. What is a Dendrite Ulcer? A dendritic ulcer occurs when the virus affects the cornea, which is the clear window at the front of your eye.

Can you get Ramsay Hunt twice?

Ramsay Hunt syndrome is caused by the same virus that causes chickenpox. After chickenpox clears up, the virus still lives in your nerves. Years later, it may reactivate. When it does, it can affect your facial nerves.
