ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. often times, all ewing's sarcoma of bone have radiographic abnormalities. diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. bone to bone metastasis occurs, but soft tissue retro bulbar metastasis is rare. this...

PURPOSE We present spontaneous retrobulbar hemorrhage in a 52-year-old woman with history of breast cancer and tamoxifen intake which was first thought to be an orbital metastasis. CASE REPORT A 52-year-old woman with history of breast cancer and tamoxifen intake was referred due to severe proptosis and visual loss. Orbital imaging showed an intra-conal mass. After exploration, multiple fragm...

BACKGROUND/AIM It is known that glaucoma is associated with elevated intraocular pressure and obesity, yet the precise etiology remains unclear. The aim of this study was to determine whether there is a potential causality between the volume of retrobulbar adipose tissue and the level of intraocular pressure in obese subjects compared with non-obese. METHODS A total of 100 subjects were divid...

CASE SUMMARY An 18-month-old male neutered Ragdoll cat presented with an 8 week history of progressive unilateral right-sided mucopurulent nasal discharge and exophthalmos. Magnetic resonance imaging revealed a heterogeneous right retrobulbar mass and bilateral nasal cavity disease. Filamentous structures seen on cytology of retrobulbar and nasal biopsies were mistakenly identified as filamento...

Demyelinating optic neuritis is the commonest cause of optic neuropathy in young adults. Retrobulbar optic neuritis is one of the frequent clinical forms of demyelinating optic neuritis. We report a case of a 28-year-old lady who presented with blurring of vision in the right eye for one month and pain on eye movement. Fundi examinations were normal. Initial suspicion was that of retrobulbar op...

A dog presented with a retrobulbar mass, diagnosed histopathologically as malignant spindle cell neoplasia. Emergence of analogous findings in the contralateral orbit prompted extended immunohistochemistry of the original mass and reassignment to idiopathic sclerosing orbital inflammation. Early incisional biopsy with extended immunohistochemical analysis should be considered for canine orbital...

Hille DM, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-223003 Description This report of a mass in the upper eyelid resulting from long-term complications of heavy liquid tamponade therapy of retinal detachment is a good example of learning from rare cases. Retinal detachments may be repaired by scleral buckling, vitrectomy surgery or by a combination of both techniques. Retinal detachments r...

BACKGROUND/AIM Retrobulbar (optic) neuritis is inflammation of the optic nerve that may cause a complete or partial loss of vision. This inflammation can affect a part of the nerve within the eyeball (neuropapillitis) or a part of the nerve behind the eyeball (retrobulbar neuritis). The aim of this study was to establish whether there is a correlation between the diameter of a retrobulbar part ...

AIM To investigate the effect of retrobulbar and subconjunctival anaesthesia on retrobulbar haemodynamics by colour Doppler imaging. METHOD 39 patients (mean age 71 (SD 9) years; 19 females, 20 males) undergoing planned cataract surgery were included in the prospective study. Colour Doppler imaging (Siemens Sonoline Sienna, Germany) was performed before, directly after either subconjunctival ...

Day-case cataract surgery and the need for local anaesthesia are likely to increase. Retrobulbar (and peribulbar) anaesthetic injection is a common technique in cataract surgery, but serious complications are persistently reported. Subconjunctival injection is an alternative that avoids these risks. This retrospective study compares two groups of patients that underwent extracapsular cataract s...
