Introduction:

orbital tumors, in spite of not being so frequent, represent a challenge for the Ophthalmology Specialist in their diagnosis and management. Malignant lesions are more frequent, as well as primary lesions of the orbit, in which non-Hodgkin's lymphoma represents the highest number of cases.

Objective:

to deepen the current knowledge on the diagnostic and therapeutic approach to this disease.

Methods:

theoretical and empirical methods were used to analyze the updated knowledge on this disease, a bibliographic review was carried out in different databases, both in English and Spanish, and a series of principles on clinical presentation, diagnosis of certainty and adequate treatment were presented.

Conclusions:

orbital lymphoma is very rare, but should be considered in a patient with proptosis or ocular symptoms and an orbital mass, especially unilateral. Imaging studies and biopsy should be performed for diagnosis and staging. Treatment should be administered as soon as possible and usually consists of radiotherapy. The prognosis is usually favorable.
