Homonymous Hemianopia with Macular Sparing: Clinical and Radiological Correlation - case presentation

A classical case of homonymous hemianopia with macular sparing secondary to stroke involving the occipital cortex is presented. The lesion was localized more anteriorly where anatomically the peripheral vision function in the cerebral cortex is located. Sparing of the occipital pole was responsible for macular sparing in the patient. In this case there was good co-relation between clinical symptoms and radiological findings. This case highlights that well conducted visual field testing and careful evaluation of the visual field defect pattern can localize the lesion site approximately along the optic pathway that can be confirmed by modern imaging modalities.Key words: brain, magnetic resonance imaging, macula, occipital lobe, vision, homonymous hemianopia, strok

Traumatic Retrobulbar Haemorrhage: Aetio-pathology and management

Retrobulbar haematoma following blunt orbital trauma is a rare,but potentially serious complication, since it can evolve rapidly from visual impairment to permanent loss of vision. This sight-threatening situation most commonly arises from orbital bleeding accompanying undisplaced fractures of the orbital walls, an event that increases the pressure inside theorbit and results in vascular damage to the optic nerve. The clinical presentation includes pain, exophthalmos with proptosis, and internal ophthalmoplegia, with impairment or loss of the pupillary reXex. A thin-layer orbital CT scan is an essential diagnostic aid. Therapy is based on orbitaldecompression, via different surgical approaches, with the intention of reducing the pressure on the nerve and vascular structures inside the orbit. Emergent management is of utmost importance as any delay between the onset of symptoms and treatment can have a significant effect onrecovery

Large cerebello-pontine epidermoid tumor in a child

Cerebellopontine angle lesions are more commonly found in adults; however, they are uncommon in children. 13 year female child presented with progressive cerebellar signs and decreased hearing in left ear. Magnetic resonance imaging was suggestive of left cerebello-pontine angle epidermoid tumor that was treated surgically. In this rare case we discuss the imaging findings and review the relevant literature

A rare complication of Nd-YAG capsulotomy: Propionibacterium acnes endopthalmitis

Abstract Posterior capsular opacification, also known as after cataract develops in 33 % of patients after uneventful cataract surgery. Nd-YAG Laser capsulotomy is the treatment of choice for PCO and is routinely performed by the general ophthalmologist on an OPD basis. Endophthalmitis, although a rare complication after Nd-YAG Laser capsulotomy, has been reported in the literature. We report a case of Propionibacterium acnes endophthalmitis following laser capsulotomy and the possible mechanism of its occurrence

Unusual Sites of Epidermoid Cyst

Epidermoid cyst is usually due to infection of pilosebaceous gland or due to traumatic migration of epidermis to the deeper structure of skin. They may present in any place of body which is lined by squamous epithelium. They are rarely present in head neck and in oral cavity. We are presenting rare cases of epidermoid cyst presenting in post aural region and floor of mouth
