ABSTRACT
Pott's puffy tumor, a feature of osteomyelitis of the frontal bone, is a rare entity, especially in adults. Sir Percival Pott originally described this condition as a complication of trauma to the frontal bone. This is also a recognized complication of fronto-ethmoidal sinusitis. We present a rare case of Pott's puffy tumor caused by an insect bite presenting initially as a preseptal cellulitis and explore its pathogenesis and management.

a 24-years-old male Jamaican building worker developed cataracts four months after electrical injury from a high tension cable. His visual acuity fell to perception of hand movements at 1 metre. Extracapsular cataract extraction and intraocular lens implantation restored his visual acuity to 20/25(6/7.5). Mechanisms for this unusual complications of electrical injury are discussed

Ophthalmic assessment was performed on a random sample of 178 black Jamican diabetics. Retinopathy was present in 69%. Severe visual loss (V.A. < ou =**5/200 or < ou = **2/60) had occurred in 11% of eyes, and maculopathy was the commonest cause. Another 9% of eyes were at "high risk" of severe visual loss 2 years from proliferative disease. Diabetes mellitus of greater than 10 years duration was a strong risk factor for retinioathy, maculopathy, severe visual loss and "high risk" of severe visual loss
