Abstract Details

Purpose:

The purpose of this project is to study the clinical features and functional outcomes of toxic-allergic keratouveitis under self overdosing of local anesthetics.

Setting:

Kazakh Eye Research Institute, Almaty, Kazakhstan

Methods:

In the clinical observation there have been participated 12 patients with the diagnosis of toxic-allergic keratouveitis. The ages of the patients varied from 21 to 68 years. The patients used until 1 bottle (15 mL) of the local anesthetic per day to relieve pain, including the night time. 11 patients independently used local anesthetic Alkain (active ingredient - 0.5% Proparacaine Hydrochloride), 1 patient is instilled into the eyes local anesthetic Innokain (active ingredient - 0.4% Oxybuprocaine).

Results:

Clinical features after instillation of the local anesthetics are moderate chemosis and limb ischemia. In addition, the presence of the annular infiltrate in the deep layers of the stroma has been revealed in all patients. In 2 cases, there was hypopyon until the middle of the pupil.

Conclusions:

Due to the wide availability of local anesthetics (Alkain and Innokain in these cases) there were observed symptoms of toxic-allergic keratouveitis in patients with a possible further complication of the disease. Such cases often occur in developing countries and they are threatening public health.
