This paper presents a review of a dog, with a retrobulbar chondrosarcoma, which was admitted for surgery for visible changes in his eye during inspection. Orbital neoplasia in dogs may be primary and secondary. Sixty percent of orbital neoplasia in dogs are primary, ninety percent of which are malignant. Retrobulbar neoplasms are rare and in their early stage represent a diagnostic challenge. C...

The effect of the local anaesthetic agent, etidocaine, on the optic nerve function was examined at regional ophthalmic anaesthesia. Visual evoked potential (VEP) was recorded before and 15 minutes after injection of the anaesthetic agent in 19 patients scheduled for elective cataract surgery (seven retrobulbar and 12 periocular). Both the anaesthetised--that is, the eye to be operated on--and t...

Aim: To assess efficacy and complications of trans-Tenon’s retrobulbar infusion of triamcinolone acetonide for posterior uveitic inflammation. Methods: Non-randomised, uncontrolled, retrospective study of 51 eyes of 37 patients who underwent triamcinolone infusion for vitritis, cystoid macular oedema (CMO), or posterior retinal vasculitis using a long blunt cannula via an incision made through ...

This prospective double-blind study compared the effectiveness of EMLA with alfentanil and placebo in reducing the overall pain during ophthalmic nerve blocks. Seventy-five patients scheduled for cataract surgery were divided into three groups. Patients in the EMLA group had EMLA cream applied over skin areas corresponding to injection sites for retrobulbar and facial nerve blocks one hour befo...

Advances in cross sectional imaging methods such as ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) have greatly contributed to the understanding and diagnosis of intraocular and retrobulbar diseases. While ultrasound is an excellent method for assessing the intraocular structure it is less capable to fully assess the retrobulbar space due to the osseous boundaries tha...

Giant cell arteritis (GCA) is a chronic vasculitis involving medium and large sized arteries. A 73-year-old male presented with right eye visual loss and jaw claudication associated with photosensitivity, supraorbital and retrobulbar pain. Evaluation demonstrated bitemporal tenderness, elevated ESR, CRP, leukocytosis and positive PANCA. Stranding and abnormal enhancement of right retrobulbar fa...

Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy the right eye, wide retrobulbar anatomy exposure, dissection structures, identification and distal section optic nerve followed by anastomosis either vicryl (group 1) or fibrin glue 2). Electroretinography recording was performed bef...

BACKGROUND We present a case of a patient initially presenting with multifocal choroiditis (MFC) in one eye. She subsequently developed lesions most consistent with punctate inner choroidopathy (PIC) in the contralateral eye, followed by acute vision loss from retrobulbar optic neuropathy. Optic neuropathy has been well described in the setting of MFC. There is, however, only one report of its ...

OPTIC neuritis is a rare sequel of cataract extraction. Reese and Carroll (1958) described seventeen cases, of which nine were their own. Three of the patients, who had both eyes operated on, suffered the same complication in the second eye, but seven other patients had no complications in the second eye. They had found no other definite cases in the literature, and we have found only two furth...
