PURPOSE Anterior proliferative vitreoretinopathy (PVR) is an important cause of persistent or recurrent retinal detachment (RD). Endoscopy provides 360° panoramic viewing of the vitreous cavity and high-magnification viewing of the anterior vitreous base (AVB). This study describes the 'in vivo' anatomy and pathoanatomy of the AVB using an ocular endoscope in RD and anterior PVR. METHODS An i...

PURPOSE To explore the attachments of the posterior zonule and vitreous in relation to accommodation and presbyopia in monkeys and humans. METHODS Novel scanning electron microscopy (SEM) and ultrasound biomicroscopy (UBM) techniques were used to visualize the anterior, intermediate, and posterior vitreous zonule and their connections to the ciliary body, vitreous membrane, lens capsule, and ...

The occurrence of haemolytic glaucoma in phakic eyes due to ghost cells has not previously been reported. Three cases of haemolytic glaucoma occurring over two years after massive vitreous haemorrhage in patients with an intact lens iris diaphragm are described. In one case there was histological confirmation of the presence of ghost cells in the anterior chamber. The mechanism proposed for the...

BACKGROUND Ocular biometric parameters can be influenced by race, ethnicity, and genetics; their differences across different populations can probably explain differences in refractive errors in these populations. The aim of this study is to determine the normal range of axial length, anterior chamber depth, lens thickness, and vitreous chamber depth in the population of Shahroud in the north o...

PURPOSE To determine the incidence of and risk factors for posterior capsule rupture and vitreous loss during phacoemulsification performed by ophthalmology residents. SETTING Academic ophthalmology resident training center, Tehran, Iran. DESIGN Cross-sectional study. METHODS This study included patients who had phacoemulsification by ophthalmology residents from August 2010 to August 201...

Vitreous hemorrhages are important clinical manifestations of proliferative diabetic retinopathy. Non-cleared vitreous hemorrhages could lead to hemosiderosis bulbi and glaucoma. Here, we describe the case of a type 2 diabetic patient presenting anterior segment and vitreous hemorrhages that resolved three days after treatment with a single intravitreal injection of dobesilate.

INTRODUCTION Posterior capsule rupture causes instant vitreous contamination, resulting in endophthalmitis. However, transfer of intracameral moxifloxacin (MFLX) to the vitreous has not been examined in detail. We investigated vitreous antibiotic concentrations following intracameral MFLX in both ruptured and intact posterior capsular eyes. METHODS Experiment 1: Intraocular lenses were insert...

The human vitreous contains primarily water, but also contains proteins which have yet to be fully characterized. To gain insight into the four vitreous substructures and their potential functions, we isolated and analyzed the vitreous protein profiles of three non-diseased human eyes. The four analyzed substructures were the anterior hyaloid, the vitreous cortex, the vitreous core, and the vit...
