[The state of ocular neurosensory apparatus in diabetes mellitus].

Diabetes mellitus is one of the most common chronic diseases in the world. Among its late complications that can lead to disability is diabetic neuropathy (DN). Patients diagnosed with DN often also have diabetic retinopathy (DR).

[Dynamics of electrophysiological parameters of the retina after surgical treatment of idiopathic macular hole].

Aim: to study the dynamics of recovery of electrophysiological parameters of the retina after surgical treatment of idiopathic macular hole (IMH) and to assess their relevance to functional prognosis of the operation.

Material And Methods: The study included 118 patients (120 eyes) examined before and after successful IMH surgery. The patients underwent electroretinography (Ganzfeld and multifocal), static computed perimetry, and optical coherence tomography.

[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.

[Electrophysiological parameters of the retina in idiopathic macular hole].

Aim: To investigate the nature and range of electrophysiological disturbances in idiopathic macular hole (IMH) and establish their relationship with structural parameters of the retina.

Material And Methods: The study included 249 patients (280 eyes) with IMH. All of them underwent ganzfeld and multifocal electroretinography (ERG), optical coherence tomography, and evaluation of retinal electrical sensitivity and analyzer lability.

[Intraocular lens power calculation in silicone-filled eyes].

Aim: to evaluate the accuracy of different modified methods for axial length (AL) measurement in silicone-filled eyes.

Material And Methods: The study was conducted in a group of 60 patients (60 eyes) with silicone oil tamponade (Oxane 1300 cst). Axial length measurements were taken using IOL Master optical coherence biometry ('silicone-filled eye' mode) and modified A-scan ultrasound biometry (velocity of ultrasound passing through the vitreous body set at 980 m/s and 1000 m/s).
