AIMS To compare iridotomy outcomes in dark irides by 1064 nm pulsed Nd:YAG laser with and without 532 nm continuous-wave Nd:YAG (frequency-doubled) green laser pretreatment. METHODS 30 patients with occludable anterior chamber angles underwent bilateral standard pulsed 1064 nm Nd:YAG laser iridotomy with one eye randomly assigned to sequential(More)
PURPOSE Few studies have assessed optic disk and retinal morphology in infants. Here the optic disk and optic disk-to-fovea distance were measured in preterm and full-term infants in vivo. METHODS Optic disk (OD) dimensions and the center-to-center distance between the OD and the macula were measured using digital imaging in infants undergoing routine(More)
PURPOSE To compare the preoperative evaluation of secondary intraocular lens (IOL) implantation in aphakic adults following cataract extraction in childhood using slitlamp examination and high-frequency ultrasound (HFU). METHODS In a prospective case series, patients who had had lensectomies for congenital cataracts without primary implantation IOL were(More)
PURPOSE To determine the preretinal distribution of oxygen in advanced proliferative diabetic retinopathy, and to investigate the relationship between intraocular oxygen tensions and vitreous cytokine concentrations. DESIGN Comparative cross-sectional study. METHODS Oxygen levels were measured at sites in the vitreous and at the inner retinal surface(More)
AIM To evaluate outcome following retinectomy surgery and to identify factors that predict visual outcome. METHODS This was a retrospective uncontrolled interventional case-series of patients who underwent retinectomy surgery at Moorfields Eye Hospital (London, UK) during a 2-year period. We recorded peri-operative factors with the potential to influence(More)
Metastatic squamous cell carcinoma (SCC) of the conjunctiva is uncommon in Western countries. A Nigerian patient who presented with right lower lid swelling treated as a chalazion is described here. She re-presented 5 months later with widespread metastatic conjunctival SCC and positive HIV serology. Conjunctival SCC may be difficult to distinguish on(More)
Sputum viscosity: correlation with chemical and clinical features in chronic bronchitis. A series of outpatient chronic bronchitics with severe airways obstruction was studied monthly over a five-viral antibodies were measured. Mucoid sputum showed a highly significant correlation between pourability grade and viscosity. The mean coefficient of variation(More)
AIM Silicone oil is a useful tamponading material used in complex vitroretinal surgery. However, the use of silicone oil is associated with emulsification which can lead to vision threatening complications. The authors developed an experimental model to study the effect of encircling band on silicone oil emulsification. METHODS Two identical artificial(More)
Rosai-Dorfman disease is a rare condition characterised by massive lymphadenopathy involving the orbit in 11% of cases. Immunohistochemical analysis remains key to the diagnosis with characteristic immunohistochemical S100 staining of histiocytes and lymphocyte phagocytosis. We report the case of a 43-year-old female with recurrence of bilateral orbital(More)
PURPOSE To evaluate the efficacy and rotational stability of the MicroSil 6116TU foldable 3-piece silicone toric intraocular lens (IOL) (HumanOptics). SETTING Department of Ophthalmology, Hillingdon Hospital, Uxbridge, Middlesex, United Kingdom. METHODS This prospective observational study included 21 eyes of 14 consecutive patients with more than 1.50(More)
