Isolation of a bioactive Ca(2+)-mobilizing complex lipid from bovine vitreous body.

Vitreous body extracts show a potent Ca(2+)-mobilizing activity on fibroblast cells. This Ca2+ signal is complex, and due to the presence of two different bioactive substances. The first one was identified as acid FGF. The second one was shown to be a low molecular weight substance identified as a complex lipid by a combination of chromatographic and biochemical data. This finding raises the possibility that non-classical substances with growth factor-like activity might play a role in the regulation of proliferative processes in the eye.

[Primary pars plana vitrectomy in the treatment of penetrating eye injuries involving intraocular foreign bodies in the vitreous body ].

The method of choice in the treatment of penetrating eye injuries affecting the vitreous body with an intraocular foreign body is in the majority of patients primary pars plana vitrectomy with transvitreal extraction of the foreign body (FB). During the period from April 1999 till September 2000 the authors treated thus at the Ophthalmological Clinic of the General Faculty Hospital and 1st Medical Faculty Charles University Prague 26 eyes of 26 young men with an average age of 34 years. The mean interval between the injury and primary PPV was 8.5 days. The patients were followed up on average for 23.5 months. The entrance of the penetrating injury was in 17 eyes in the cornea or limbus, in 9 eyes in the sclera. In two eyes posttraumatic endophthalmitis developed. The intraocular FB was 6 mm2 in size in 16 eyes and 6-20 mm2 in 10 eyes. In primary PPV we indicated in 14 eyes internal tamponade with gas or silicone oil. On account of late retinal complications which developed as a result of proliferative vitreoretinopathy we indicated in eight eyes PPV reoperation. At the end of the investigation period in 3 eyes inoperable detachment of the retina developed. As the main negative prognostic factor for final visual acuity the authors evaluated a size of the FB greater than 6 mm2, other negative prognostic factors are the scleral entrance injury, complications of the entrance injury (prolapse of the iris, vitreous body, haemophthalmus) and the development of posttraumatic exogenous endophthalmitis.

[Case study of a solitary vitreous body cyst].

Vitreous cysts are rare and their origin unclear. We present a case of a 47-year-old woman who, after undergoing retinal detachment surgery on several occasions, developed disturbing vitreous opacities with which she presented for possible vitrectomy. Besides the typical postoperative vitreous condensations and opacifications, a solitary spherical cystic structure was present in the anterior vitreous cavity. The cystic structure was attached at its posterior aspect onto a vitreous membrane and was otherwise floating within a vitreous body lacuna. The vitreous opacities and the cyst were removed by performing a pars plana vitrectomy. The patient's visual acuity improved from 0.5 to 0.7. We presume that the cyst was acquired in association with the retinal detachment or the operations.
