Inflammatory myofibroblastic tumor of the orbit: A clinico-pathological study of 25 cases
Conclusion IMT is a distinct entity which may occur in the orbit primarily. It should be considered in differential diagnosis in all orbital masses, particularly with onset of acute or subcronic inflammation. Surgical biopsy associated to a partial debulcking of the tumor, avoiding to damage adjacent vital structure may contribute to improve the outcome. Steroid therapy, seems to be the suitable as first line medical therapy, although, as reported in literature, not all cases respond to this treatment regimen. Radiotherapy, may be considered as an alternative therapy. Recurrences occurred in 24% of patients and may be trea...

Spontaneous breakage of intracorneal ring segments (ICRS) 8 years after implantation
We present a case of spontaneous in situ breakage of intracorneal ring segments (ICRSs) 8 years after their implantation in a patient with keratoconus. The patient presented to our clinic with a red and painful right eye that had not improved despite topical steroids and antibiotics. The decision was made to explant the broken ICRSs from the cornea and send them for laboratory analyses, by which manufacturer defects were excluded. It is noteworthy that corneal curvature re-steepening was observed 4 months after ICRS removal despite the performance of crosslinking (CXL) 1 year prior to ICRS implantation. (Source: Saudi Jour...

Primary mesenchymal chondrosarcoma of the orbit: Histopathological report of 3 pediatric cases
We describe 3 additional pediatric cases with primary orbital MCS and they were all males. Our cases presented with proptosis and calcific orbital masses on imaging studies. Histopathological examination of the excised masses shared the typical presence of undifferentiated mesenchymal cells and immature areas of cartilage. The diagnosis of MCS was further confirmed by immunohistochemical staining. Brief review of the literature in relation to this diagnosis in the orbit is also presented.

Customized 3D Printing: A novel approach to migrated orbital implant
Publication date: Available online 15 March 2018 Source:Saudi Journal of Ophthalmology Author(s): Tarjani V. Dave, Gayatri Gaur, Nikhil Chowdary, Dhruv Joshi This paper describes a novel approach to treat migrated orbital implants post socket surgery. Implant migration may hinder the final aesthetic outcome of a custom ocular prosthesis. Once an implant migrates within the orbit there tends to be fibrosis around the implant. This fibrosis does not allow for centeration of the implant during repeat surgery. Hence treatment of a migrated implant traditionally involves implant removal with dermis fat grafting. Dermis fa...
