[Scanning electron microscopy results of the vitreous body in asteroid hyalosis].

Purpose: To evaluate the structure of vitreous body in asteroid hyalosis by low vacuum scanning electron microscopy.

Material And Methods: The material of the study was samples of the vitreous body obtained from 7 patients aged from 62 to 72 years with vitreomacular traction syndrome during vitrectomy. In all cases, clinical manifestations of asteroid hyalosis (the presence of multiple point-like echo-positive inclusions) were identified during the preoperative examination.

[Current approach and the role of laser photocoagulation in the treatment of retinal vein occlusions].

Despite the emergence of new approaches in the treatment of retinal vein thrombosis and post-thrombotic complications, namely, intravitreal pharmacotherapy and surgical treatment, laser photocoagulation continues to play a significant role in the management of patients with this pathology. Although the method of laser photocoagulation has been used for quite a long time, different views exist on its indications and execution in specific clinical situations. At that, not all opinions regarding the use of laser photocoagulation in thrombosis are based on convincing clinical studies.

[Biometric parameters of vitrectomized eyes].

Aim: To analyze changes in various biometric parameters after vitrectomy.

Material And Methods: A total of 50 patients (50 eyes) were followed up. All of them underwent vitrectomy for idiopathic epiretinal fibrosis and macular hole.

[Combined transscleral and transpupillary thermotherapy in large vasoproliferative retinal tumors].

Three cases (two patients) of large vasoproliferative retinal tumor treatment by an original method, which includes intraoperative non-contact transscleral thermotherapy and subsequent transpupillary thermotherapy, are described. Positive anatomical results were achieved in all three cases.

[Visual fixation features after treatment of exudative age macular degeneration].

Changes of visual fixation in patients with choroidal neovascularitation (CNV) associated with age macular degeneration (AMD) after bevacizumab are studied. 45 patients (45 eyes) with active CNV treated with intravitreal bevacizumab were enrolled into the study. Visual fixation was studied before and 3-6 months after treatment using original method that included fundus foto and fluorescein angiography.

[Surgical treatment policy using recombinant prourokinase for submacular hemorrhages].

An immunofluorescence technique was used to study the transretinal penetration of intravitreal fibrinolytic agent Hemase (a recombinant urokinase) in an experiment on 4 rabbit eyes. Hemase (54 kD) was proved to be able to penetrate across all retinal layers 2 hours after intravitreal administration. The efficacy of Hemase was tested in the treatment of submacular hemorrhages (SMH) of various etiology.

Management of submacular hemorrhage with intravitreal versus subretinal injection of recombinant tissue plasminogen activator.

Aim: To compare the efficacy of pars plana vitrectomy (ppV) with intravitreal injection of recombinant tissue plasminogen activator (rtPA) and gas versus ppV with subretinal injection of rtPA and intravitreal injection of gas.

Methods: Nonrandomized, retrospective, interventional, comparative consecutive series including 47 patients with submacular hemorrhage. Eighteen patients were treated with ppV, intravitreal injection of rtPA and 20% SF6 gas [group A: mean age 78 years, mean duration of symptoms 6.

Optical coherence tomography findings in idiopathic juxtafoveal retinal telangiectasis.

Purpose: To describe optical coherence tomography (OCT) findings in patients with juxtafoveal retinal telangiectasis (JRT).

Methods: Fourteen consecutive patients (28 eyes) with JRT (12 patients with JRT type II, one with JRT type I and one with JRT type III) were examined using fluorescein angiography (FA) and OCT.

Results: Despite prominent leakage in FA, macular oedema was absent in all 26 eyes with type II JRT.
