Keratitis Caused by Rhinitis and Pharyngitis

Introduction

Keratitis is an inflammation of the cornea, the clear outermost layer of the eye. It can be caused by a variety of factors, including bacteria, viruses, fungi, and parasites. In some cases, keratitis can also be caused by allergic reactions or autoimmune disorders.

Rhinitis is an inflammation of the nasal passages, while pharyngitis is an inflammation of the pharynx, or throat. Both rhinitis and pharyngitis are common upper respiratory tract infections that are often caused by viruses. In some cases, however, these infections can also be caused by bacteria.

How Rhinitis and Pharyngitis Can Cause Keratitis

Rhinitis and pharyngitis can cause keratitis in a number of ways. First, the inflammation associated with these infections can lead to the production of tears that contain inflammatory mediators. These mediators can damage the cornea and cause keratitis.

Second, the viruses or bacteria that cause rhinitis and pharyngitis can also directly infect the cornea. This can lead to the development of a corneal ulcer, which is a serious infection that can lead to vision loss.

Third, rhinitis and pharyngitis can also cause keratitis by blocking the tear ducts. This can lead to a build-up of tears on the surface of the eye, which can create a favorable environment for the growth of bacteria and fungi.

Symptoms of Keratitis Caused by Rhinitis and Pharyngitis

The symptoms of keratitis caused by rhinitis and pharyngitis can include:

Eye pain

Redness of the eye

Blurred vision

Tearing

Sensitivity to light

Discharge from the eye

Diagnosis of Keratitis Caused by Rhinitis and Pharyngitis

The diagnosis of keratitis caused by rhinitis and pharyngitis is based on a combination of the patient's symptoms and a physical examination of the eye. The doctor will also likely ask the patient about their medical history, including any recent cases of rhinitis or pharyngitis.

In some cases, the doctor may also order tests to confirm the diagnosis. These tests may include:

A corneal scraping: This test involves scraping a small sample of cells from the surface of the cornea. The cells are then examined under a microscope to look for signs of infection.

A culture: This test involves growing a sample of bacteria or fungi from the cornea in order to identify the organism causing the infection.

Treatment of Keratitis Caused by Rhinitis and Pharyngitis

The treatment of keratitis caused by rhinitis and pharyngitis depends on the underlying cause of the infection. If the infection is caused by bacteria, the doctor will prescribe antibiotic eye drops or ointments. If the infection is caused by a virus, the doctor may prescribe antiviral eye drops or ointments.

In some cases, the doctor may also prescribe other medications to help relieve the symptoms of keratitis. These medications may include pain relievers, anti-inflammatory drugs, and artificial tears.

Prevention of Keratitis Caused by Rhinitis and Pharyngitis

There are a number of things that can be done to prevent keratitis caused by rhinitis and pharyngitis. These include:

Washing your hands frequently with soap and water
