[The special problems of lymphangioma perioculare and hemifaciale (author's transl)].

The authors describe two cases of the rare disease lymphangioma hemifaciale. Every ophthalmologist should know this disease in view of the complications such as hemorrhage or erysipelas. Treatment methods are discussed. Furthermore, lymphangioma must be taken into consideration in the differential diagnosis of ptosis, protrusio bulbi, protrusio conjunctivae and congenital hemifacial hypertrophy.
