Introduction: The various orbital lesions range from a cyst which might be due to trauma, vascular or congenital, to tumors which are of benign or malignant cause, which are considered as a challenging problem commonly faced by ophthalmologist.
Aim: To study the prevalence, etiopathogenesis and the treatment modalities for the various cystic lesions of the orbit.
Materials and Methods: A prospective longitudinal study was conducted for a period of one year between June 2015 and May 2016 in the department of ophthalmology of Government Mohan Kumaramangalam Medical College Salem. A total of 130 patients with the sign of proptosis were reported during that said period. Out of the 130 patients 37 patients who are diagnosed to be having cystic lesions were taken up for study analysis. Cystic lesions which were confined to conjunctiva, eyelid and intraocular structures were excluded, but lesions involving the anterior compartment along with conjunctiva involvement were included in the study. A semi-structured questionnaire was prepared to collect the history related to demographic details, history regarding the onset, duration, progression and the past history. It was followed by a complete general and ocular examination including visual acuity, examination of anterior and posterior segments, examination of the mass, hertelsexophthalmometry, field charting, colour vision, refraction, IOP measurement and forced duction test.
Results: Among the various type of cystic lesions reported in our study subjects parasitic lesions were found to be the most common type which was present in more than 30% of the patients and it was followed by dermoid cyst in 24.3% of the patients and the other lesions reported were mucocele (21.6%), hemagioma (10.8%) and lymphangioma (8.1%). Only one patients had a cancerous lesion namely adenoid cystic carcinoma. The mean age for the most of the cystic lesions like parasitic, dermoid cyst, vascular lesions like hemangioma and lymphangioma was found to be less than 15 years, whereas for mucocele and adenoid cystic carcinoma the mean age was found to be more than 30 years.
Conclusion: Every orbital lesion which comes into notice because of symptoms should be evaluated thoroughly to rule out malignant potential and also to assess the mass effect in it. As most of the lesions occur in children, it is of utmost importance to intervene early as it may be vision threatening.
