PURPOSE To describe the morphologic alterations in ultrasound biomicroscopy (UBM) present in peripheral vitreoretinal toxocariasis. METHODS An observational prospective study of case series. Fifteen eyes of 15 patients with clinical and laboratory diagnosis of peripheral vitreoretinal toxocariasis were enrolled. The patients were submitted to UBM examination of the region corresponding to the...

Since the first vitrectomy surgery was used for treatment of vitreoretinal diseases, surgical techniques and instrumentation have been rapidly improved in the past decades. However, there are complicated vitreoretinal diseases that cannot be successfully treated, even with state-of-the-art surgeries. The outcomes of some complicated cases are still poor due to different reasons and debates stil...

A Vitreoretinal Surgery System Fluidics Failure Modes and Effects Analysis Jennifer Grega Eyesight is something that is vital to all human beings. The concept of vitreoretinal surgery is an amazing achievement of modem medicine to help treat patients that might otherwise be blind. Vitreoretinal surgery has enhanced and restored vision in numerous individuals due to the forefront of new instrume...

SUMMARY We have developed two novel methods for Singular Value Decomposition analysis (SVD) of microarray data. The first is a threshold-based method for obtaining gene groups, and the second is a method for obtaining a measure of confidence in SVD analysis. Gene groups are obtained by identifying elements of the left singular vectors, or gene coefficient vectors, that are greater in magnitude ...

A variety of stock (Matthiola ilzcana R. Br.) known as Snowflake has been shown by FROST (1919) to produce frequent mutants of at least eight distinct kinds. These mutant forms are genetically inconstant, part of the progeny always being normals. These forms have been determined (FROST and MANN 1924, and papers in preparation) to be trisomic. Within, the variety Snowflake, all plants cytologic...

In cases with persistent primary vitreous in full-term infants there were vitreoretinal reactions including vitreoretinal anastomoses of blood vessels, vitreoretinal strands, traction folds of the retina, avascular retinal areas, hypoplasia of retinal blood vessels, rarefaction of retinal ganglion cells, and ischaemic structural changes of the retina. New vessel formation on the surface of avas...

Vitreomacular traction (VMT) syndrome and macular hole (MH) are disease processes that are caused by anomalous separation of the vitreous from the macula. Until now, management of these conditions has involved vitreoretinal surgery. Clinical trials have shown that a single intravitreal microplasmin (ocriplasmin) injection can induce separation of the vitreous from the macular surface and thereb...

The vitreoretinal interface is involved in a wide range of vitreoretinal disorders and separation of the posterior vitreous face from the retinal surface is an essential part of vitrectomy surgeries. A diverse range of enzymatic and non-enzymatic agents are being studied as an adjunct before or during vitrectomy to facilitate the induction of posterior vitreous detachment. There is a significan...

type transthyretin as well as other fibrillar proteins. To our knowledge, this is the first case report of vitreoretinal amyloidosis in the absence of transthyretin mutations. In addition, no signs of systemic amyloidosis suggestive of FAP were evident 7 years after the patient’s initial presentation, although we cannot exclude the possibility of a subclinical level of amyloid deposition in oth...
