The sedative effects of intramuscular (IM) alfaxalone in 2-hydroxypropyl-beta-cyclodextrin (alfaxalone-HPCD) were evaluated in cats. The cats were treated with alfaxalone-HPCD in five occasions with a minimum 14-day interval between treatments: an IM injection of 1.0 mg/kg (IM1), 2.5 mg/kg (IM2.5), 5 mg/kg (IM5) or 10 mg/kg (IM10), or an intravenous injection of 5 mg/kg (IV5). The sedative effe...

Aims—To describe two phenotypic variations of autosomal recessive retinal dystrophy occurring in a consanguineous family in a pseudodominant pattern, resulting from mutations in the ATP binding cassette transporter (ABCR) gene. Methods—Patients of this family underwent an extensive ophthalmic evaluation, including fundus photography, fluorescein angiography, and electroretinography (ERG). Genet...

A systemically healthy 35-year-old female has complained of blurry vision the Right Eye (RE) over past week. The best corrected visual acuity was 6120 in both eyes. Mild conjunctival injection, fine keratic precipitates, and 1 cell anterior chamber without hypopyon detected RE.

The choroid is a highly pigmented and vascularized ocular tissue providing the vascular supply of the outer retinal layers. It may be affected by various retinal and choroidal diseases such as age-related macular degeneration (AMD), polypoidal choroidal vasculopathy (PCV), central serous chorioretinopathy (CSCR), age-related choroidal atrophy (ARCA), high/pathologic myopia, choroidal melanoma, ...

Two hereditary syndromes characterized by the association of retinal changes and erythrocytic anomalies have been described: (1) Retinopathy complicating haemoglobin anomalies, thalassaemia (Rudd, Evans, and Peeney, 1953), or sickle-cell anaemia (Lieb, Geeraets, and Guerry, 1959); (2) Atypical retinitis pigmentosa with thorny erythrocytes (acanthocytosis: Bassen and Kornzweig, 1950; Kornzweig a...

Neuroimaging studies for persons in the National Collaborative Chicago-Based Congenital Toxoplasmosis Study (NCCCTS) with symptoms and signs referable to the spinal cord were reviewed. Three infants had symptomatic spinal cord lesions, another infant a Chiari malformation, and another infant a symptomatic peri-spinal cord lipoma. One patient had an unusual history of prolonged spinal cord sympt...

The cone electroretinograms (ERGs) to different chromatic stimuli were recorded in myopic subjects. Ganzfeld color flashes under bright white background illumination were used to elicit short-wavelength-sensitive (S-), and mixed long-(L-) and middle-(M-) wavelength-sensitive cone ERGs. Nineteen subjects with mild myopia (between -3.0 and -6.0 D), 12 subjects with high myopia (greater than -6.25...
