Ophthalmia nodosa
Ophthalmia Nodosa
Ophthalmia nodosa (pronunciation: /ɒfˈθælmiə nɒˈdoʊsə/) is a specific type of eye disease that is caused by the irritation from the hairs or bristles of certain types of insects or plants.
Etymology
The term "ophthalmia nodosa" is derived from the Greek words "ophthalmos" meaning "eye" and "nodosa" meaning "knotty". This refers to the nodular inflammation that characterizes this condition.
Symptoms
The symptoms of ophthalmia nodosa can vary depending on the severity of the condition. Common symptoms include redness of the eye, pain, itching, and blurred vision. In severe cases, it can lead to blindness.
Causes
Ophthalmia nodosa is caused by the irritation from the hairs or bristles of certain types of insects or plants. These hairs or bristles can become embedded in the eye, causing inflammation and irritation. Common sources include caterpillars, moths, and certain types of plants.
Treatment
Treatment for ophthalmia nodosa typically involves the removal of the offending hairs or bristles from the eye. This is usually done under a microscope by an ophthalmologist. In some cases, steroid eye drops may also be prescribed to reduce inflammation.
