Vernal eye disease in Northern Nigeria.
An analysis of 108 cases of vernal eye disease observed in Northern Nigeria. Although the bulbar and tarsal forms usually coexisted, the disease was predominantly bulbar in young children and predominantly palpebral in older patients. Chacteristic pigmentary conjunctival changes were particularly marked in young children. Corneal involvement occurred mostly in those patients with the palpebral form of the disease. The risk of permanent visual impairment in untreated cases appears to be slight.
