This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

Ophthalmic carbonic anhydrase inhibitors have been shown to improve retinal and optic nerve blood flow. However, the relative tissue distributions of commercially available carbonic anhydrase inhibitors to the optic nerve are not known. The objective of this study was to compare the ocular pharmacokinetics and tissue distribution profiles of dorzolamide and brinzolamide after single and multipl...

Measurements of interleukin (IL)-6 and -10 concentrations in the vitreous can be used to differentiate intraocular lymphoma (IOL) from uveitis. This is the first study reporting the IL-6 and -10 concentrations in the undiluted vitreous fluid and vitreous infusion fluid, which were simultaneously examined in the patients. A total of 2 females presented with intraocular inflammation, and underwen...

Our work describes the management of young patients who presents with vitreous haemorrhage. It is important to note that the causes differ significantly from adults with vitreous haemorrhage.A 16-year old patient presented with vitreous haemorrhage. B-scan ultrasonography showed hypodense elements in the retina. A vascularized gelatinous mass was revealed after vitrectomy. Later the patient dev...

An 80-year-old man had intraoperative loss of an intraocular lens (IOL) in the vitreous and simultaneous implantation of an anterior chamber lens. For the first 3 years his course was uncomplicated, but after this time he noted monocular double vision. The IOL in the vitreous had moved into the optic axis of the eye. The case presented here underlines the possibility of complications occurring ...

Here we report a case of a congenital, free-floating pigmented vitreous cyst in a child. A 12-year-old male was referred to the Ophthalmology Clinic for amblyopia on his left eye. Ophthalmologic examination revealed that the visual acuity was 20/20 in the right eye and 20/35 in the left eye. Findings of the anterior segment examination were normal. On dilated fundus examination, a free-floating...

Giant retinal tear (GRT) is defined as peripheral break extending through 900 or more of the retinal circumference in which the vitreous gel is attached essentially to the anterior flap thereby allowing independent mobility of the posterior edge of tear. GRT needs to be differentiated from Giant dialysis, which is retinal disinsertion from the ora serrata with 90 degrees or more of circumferent...

PURPOSE To describe the relationship of refractive errors and axial ocular dimensions and age-related cataract. METHODS Population-based, cross-sectional survey of ocular diseases among Chinese men and women aged 40 to 81 years (n = 1232) living in the Tanjong Pagar district in Singapore. As part of the examination, refraction and corneal curvature were determined with an autorefractor, with ...

INTRODUCTION Rabbits' eyes were exposed to vitreous humor liquefaction with Q - switched (sometimes called " giant pulses") Neodymium-Doped Yttrium Aluminium Garnet (Nd:YAG) laser using two different energy protocols (5 mJ X 100 pulse and 10 mJ X 50 pulse)with and without vitamin C administration. The histological changes in the retina were investigated to evaluate the protective role of vitami...
