BACKGROUND This study presents magnetic resonance imaging (MRI) findings of both the anterior and posterior types of persistent hyperplastic primary vitreous (PHPV) to facilitate the differential diagnosis from other intraocular abnormalities. METHODS Seventeen patients with PHPV who were evaluated using non-contrast and contrast-enhanced T1- and T2-weighted images were retrospectively review...

CASE REPORT We present the clinical case of a 68 year-old woman who developed a pupillary block acute glaucoma due to vitreous hernia into anterior chamber following posterior dislocation of the intraocular lens one month after an Nd:YAG capsulotomy. DISCUSSION We should consider these symptoms in the differential diagnosis of pseudophakic acute glaucoma, especially when visualisation of the ...

INTRODUCTION Cysticercosis, a helminthic infestation caused by Taenia solium, can produce central nervous system, muscles, visceral, subcutaneous tissues and skin manifestations. Ophthalmological involvement can affect eyelids, conjunctiva, anterior chamber, uvea, vitreous, retina, extraocular muscles and optic nerve. Simultaneous co-occurrence of intracranial and intraocular cysticercosis is a...

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 ...

INTRODUCTION Vitreous or retinal hemorrhage occurring in association with subarachnoid hemorrhage is known as Terson's syndrome. In Terson's syndrome, intracranial hemorrhages are followed by intraocular hemorrhage, classically in the subhyaloid space, but may also include subretinal, retinal, preretinal, and vitreal collections. Vitreous hemorrhage recovery is usually spontaneous in six to 12 ...

Persistant hyperplastic primary vitreous (PHPV) was described in detail as a clinical entity by Reese1 in 1955 in his Jackson Memorial Lecture. Goldberg in his 1997 Jackson Memorial Lecture2 renamed PHPV as persistent fetal vasculature (PFV). PHPV is a pathologic entity resulting from abnormal persistence of the fetal fibrovascular primitive stroma (hyaloid system) of the eye3,4 which should di...

AIM To localise the recently discovered glycoprotein opticin in the adult human eye. METHODS Polyclonal rabbit antisera were raised against two different opticin peptides. Isolated human vitreous collagen fibrils were extracted with 8 M urea and the extract analysed by SDS-PAGE and western blotting. Paraffin embedded sections from two normal eyes were subjected to immunohistochemical analysis...

Although notoriously bothersome, floaters typically resolve within weeks or months of appearing. In some cases, however, they persist for much longer.2 When floaters persist or are present at disabling levels; removal of the vitreous humor (vitrectomy) is considered a viable treatment option. However, it is a highly invasive procedure that carries a significant risk of complications, such as in...
