PURPOSE Intraocular pressure (IOP) measurements vary with different tonometers in irregular corneas. The purpose of our study was to determine the comparability of the ocular blood flow tonometer (OBF) and Tonopen with the Goldmann applanation tonometer (GAT) in measuring IOP in post-keratoplasty eyes. METHODS The IOP was measured using the OBF tonometer,(More)
BACKGROUND The clinical management of intermittent exotropia has been discussed extensively in the literature, yet there remains a lack of clarity regarding indications for intervention, the most effective form of treatment and whether or not there is an optimal time in the evolution of the disease at which any treatment should be carried out.

Orbital teratomas are rare embryonic tumors composed of a wide diversity of tissues derived from the three germinal layers. The presenting features include, a healthy newborn with extreme unilateral proptosis; marked stretching of the eyelids over a tense, fluctuating mass, with elongation of the palpebral fissure; enlargement of the bony orbit (two to(More)
BACKGROUND Accidental needle stick injuries (NSIs) are an occupational hazard for healthcare workers (HCWs). A recent increase in NSIs in a tertiary care hospital lead to a 1-year review of the pattern of injuries, with a view to determine risk factors for injury and potential interventions for prevention. METHODS We reviewed 1-year (July 2006-June 2007)(More)
Vesical varices in portal hypertension are rare. We report a patient with portal hypertension who developed recurrent painless hematuria. Cystoscopy was normal. Doppler ultrasound and MR angiography showed a dilated paraumbilical vein within the falciform ligament coursing down to the urinary bladder wall and draining into the right internal iliac vein. He(More)
PURPOSE Autosomal dominant optic atrophy (DOA) is a major cause of visual impairment in young adults that is characterized by selective retinal ganglion cell loss. To define the prevalence and natural history of this optic nerve disorder, we performed a population-based epidemiologic and molecular study of presumed DOA cases in the north of England. (More)
BACKGROUND The clinical management of intermittent distance exotropia has been discussed frequently in the literature but there is a lack of clarity regarding the indications for intervention, the most effective type and the optimum age at which it should be carried out. OBJECTIVES The objective of this review is to assess intervention criteria, the(More)
OBJECTIVE To determine the long-term outcome of treatment for threshold retinopathy of prematurity (ROP) in one UK unit. METHODS A total of 35 infants diagnosed with threshold ROP were treated by a single ophthalmologist (DGC) between 1987 and 1998. The parents of the 29 surviving patients were contacted; 21 brought their child for special review of(More)
