ABSTRACT
Takayasu's arteritis is a chronic inflammatory disease of the large and medium-sized arteries. It commonly involves the aorta with its branches and the pulmonary arteries. The retinal hemodynamics suggest that the carotid artery involvement causes diminished retinal blood flow. This is the pathogenetic mechanism of Takayasu's retinopathy with characteristic features of microaneurysms, arterio-venous anastomosis and non-perfused retinal areas. Our case presented as branch retinal artery occlusion with collaterals and iris neovascularization. The branch retinal artery, a small retinal artery occlusion in our case is an unusual presenting feature of Takayasu's aorto-arteritis.

A case of Klippel-Feil syndrome in a 12-year-old boy presentingwith the features of low set posterior hairline, short webbed neck, scoliosis and Sprengel's deformity associated with upper eyelid coloboma and pre-auricular appendages is described. Radiologically there was evidence of maldeveloped cervical and upper thoracic vertebrae associated with elevated scapula. The association of the eyelid defect and pre-auricular appendages has not been documented in the past. The current literatures based on the recent advances in understanding of molecular genetic control over embryonic development of the cervical spines were reviewed.

Rhinospordiosis, a chronic granulomatous disease of the mucocutaneous tissue, is endemic in India and other parts of South East Asia. It commonly affects the upper respiratory tract, but involvement of other sites has also been reported. A 27-year-old male patient reported with features simulating severe obital cellulitis underwent emergency managemt for his systemic problems. Subsequent CT scan and histopathological examination confirmed the diagnosis of rhinoporidiois. Definitive surgical treatment was done to remove the suspected papillomatous mass which led to marked improvement of the patient.

Iris cysts are rare clinical occurrences. They are more commonly seen secondary to trauma, medications, or parasitic infestations; or may herald the onset of an intra-ocular malignancy. Primary iris cysts without any clinically detectable aetiology are rare ophthalmic curiosities. The cyst presented here is atypical in its size, shape and location.
