Purpose: To identify the patterns of ocular injury and to determine ocular morbidity resulting from the use of firecrackers.Methods: A prospective observational study of all patients presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in South India over a one-month period around the autumn festival of Diwali. We also reviewed the published literature from around the world reporting ocular injuries due to firecrackers.Result: 49 patients were included in the study, out of which the vast majority (40/81%) were males. The mean age was 17 years. Almost an equal number of bystanders (24/48.9%) was affected as compared to people handling the fireworks (25/51%). 13 (26.53%) patients had open-globe injury whereas 33 (67.34%) patients had closed-globe injury. Twenty-two (44.8%) patients underwent surgical intervention. Eighteen (36.7%) patients had final vision less then 20/40 (range = 20/50 to No Perception of Light) with eight patients having no perception of light in the affected eye.Conclusion: Unregulated use of firecrackers can lead to significant ocular morbidity, mainly involving children, young males, and even innocent bystanders. A combination of public awareness and appropriate legislative laws should be formulated regarding the use of fireworks to decrease the load of needless blindness on society. [ABSTRACT FROM AUTHOR]

Purpose: To report a case of mesenchymal chondrosarcoma of the orbit and describe its clinical features, radiological findings and management. Method: Interventional case report. Result: A 50 year old man presented with right sided proptosis of 3 months duration. CT scan showed well circumscribed lobulated extraconal mass lesion in the inferotemporal qaudrant with specked calcification within. Patient underwent excisional biospsy with excision of mass lesion in toto. Histopathological examination was suggestive of mesenchymal chondrosarcoma of orbit. Post operatively patient was advised radiotherapy. Conclusion: Orbital mesenchymal chondrosarcoma is a rare tumor characterized by undifferentiated mesenchymal cells with islands of mature hyaline cartilage. Multimodality treatment (surgery, chemotherapy, and radiotherapy) may lead to long-term survival. [ABSTRACT FROM AUTHOR]
