Innate immunity mediated by microglia appears to play a crucial role in initiating and propagating seizure-induced inflammatory responses. To address the role of activated microglia in the pathogenesis of childhood epilepsy, we first examined the time course of microglia activation following kainic acid-induced status epilepticus (KA-SE) in Cx3cr1(GFP/+)(More)
The prevalence, incidence, and risk factors associated with proliferative sickle retinopathy (PSR) were investigated in 786 patients with homozygous sickle cell (SS) disease and 533 patients with sickle cell haemoglobin C (SC) disease. PSR was more common in SC disease, in which there was a significant predominance of males, and it increased with age in(More)
Six cases of chronic endophthalmitis following extracapsular cataract extraction and lens implantation are reviewed. All were referred for tertiary management by one surgeon over a period of just over 2 years. In two of the cases coagulase negative staphylococci were isolated and in three Propionibacterium spp were retrieved. In the remaining case a mixed(More)
Homozygous alpha+ thalassaemia (alpha-/alpha-) ameliorates some of the clinical manifestations of homozygous sickle cell (SS) disease but its effect on retinal complications remains unknown. This has been assessed by visual examination and fluorescein angiography in 39 subjects with SS disease and homozygous alpha+ thalassaemia and in 39 age/sex matched(More)
A sensitive enzyme linked immunosorbent assay (ELISA) was developed to evaluate the potential of herpes simplex virus (HSV) specific antibodies in the diagnosis of herpetic eye infection. The presence of HSV specific secretory IgA (sIgA) in tears was found to be diagnostic of infection. However, serum and tear HSV specific IgG and IgA were not considered(More)
The natural history of untreated proliferative sickle retinopathy (PSR) has been observed in 35 patients (40 eyes) with homozygous sickle cell (SS) disease and in 112 patients (114 eyes) with sickle cell-haemoglobin C (SC) disease over a mean follow-up period of 4.5 years (range 0.5-14.0 years). In both genotypes progression of PSR was most frequent between(More)
A randomized prospective clinical trial of argon laser scatter photocoagulation therapy for proliferative sickle cell retinopathy was performed on 116 patients (174 eyes) in Kingston, Jamaica. Ninety-nine eyes were treated with scatter photocoagulation and 75 eyes served as controls. The average length of follow-up was 42 months for the control eyes and 47(More)
The effect of sectoral, scatter laser photocoagulation on proliferative sickle retinopathy (PSR) was investigated by reviewing fluorescein angiograms of 88 sickle cell-haemoglobin C patients enrolled in a controlled, randomised trial. Follow-up was for a median period of 2.9 years. Complete infarction of all PSR in an eye occurred in 7 of 74 treated eyes(More)
Choroidal neovascularisation developed in 62/66 (94%) eyes followed up for a mean period of 11.2 years after treatment with xenon arc feeder vessel coagulation for proliferative sickle retinopathy (PSR). In 27 eyes the neovascularisation was chorioretinal alone and in 35 eyes choriovitreal. Chorioretinal neovascularisation (CRN) was a benign complication(More)
We present a case of acute suprachoroidal hemorrhage that developed during routine phacoemulsification in an 85-year-old patient after uneventful administration of periocular anesthesia. Pre-existing risk factors included advanced age, glaucoma, myopia, and hypertension. The scleral tunnel prevented major expulsion of intraocular contents; however, raised(More)
