Introduction: The close relationship between diseases of the paranasal sinuses system and the orbit is based on their anatomical relationship. About 60% to 80% of the osseous eye socket is made up by sinus walls. Objective: To describe evaluation of orbital complications in patient with paranasal sinuses diseases at Dr. M. Djamil Hospital Padang for 2005-2014. Method: Descriptive study we obtained from medical record of patients during January 2005- December 2014. Data collected including age, sex, diagnosis of paranasal sinuses diseases, involved sinuses, orbital involvement and ocular presentations. Results: There were fifty five patients came to Ophthalmology Department Dr. M. Djamil Hospital Padang during period 2005-2014, either directly came or consulted from ENT Department, with suspicion of orbital involvement resulted from prior paranasal sinuses diseases, 34 ( 61.8%) male and 21 (38.2%) female. The age of patients range between 4 y.o. to 83 y.o., with the most common range of age was between 51 to 60 y.o. Orbital involvelment occurred in 45 patients (81.8%) while 10 patients (18.2%) had no orbital involvement. Orbital infiltration was caused by sinonasal tumor in 35 patients (77.7%), by sinus infection in 8 patients (17.7%), and by mucocele in 2 patients (4.6%). Sinonasal tumor was the most common paranasal sinuses disease which diagnosed in 43 patients (78.2%) and maxillary sinus (58.1%) was the most common involved sinus. Majority of the patients (67.7%) had presented with proptosis followed by ophthalmoplegia (54.8%) and visual acuity reduction (43.5%). Conclusion: The most common affected person were men and more frequently found in range of age between 51 to 60 y.o. Sinonasal tumor was the most etiology of orbital abnormalities in the the present of paranasal sinuses disease with maxillary sinus was the most common involved sinus. Proptosis was the major ocular presentation which found in orbital complications caused by paranasal sinuses diseases.
