[Indications for retinal laser coagulation in the treatment of retinoschisis and rhegmatogenous retinal detachment].

Purpose: To determine the indications and assess the effectiveness of laser coagulation of the retina (RLC) after different types of surgeries for retinal detachment (RD), except vitrectomy.

Material And Methods: The study included 160 patients (165 eyes) with various types of retinal detachment and retinoschisis who remained under observation for 11 years.

Results: In case of retinal tear with a slight local RD (less than one quadrant), we recommend the use of RLC as monotherapy.

[Persistent hyaloid artery in an adult (a case report)].

The article presents a clinical case of a functioning hyaloid artery in a 69-year-old patient. The results of OCT-angiography made it possible to detect the presence of blood flow in the projection of the persistent hyaloid artery (PHA) on the cross-section and en-face images. The vascular bed of PHA spreading along the posterior surface of the lens in the form of separate branches was visualized by slit-lamp biomicroscopy.

[Results of laser confocal microscopy of the cornea in viral uveitis (a preliminary report)].

Unlabelled: Herpesviruses involve neurotropic activity (they affect nerve cells) and have the ability to induce an immune response (a special tropism for immune tissue), which provides a valid reason for studying the possibilities of visualizing nerve fibers of the cornea and Langerhans cells (LC) in viral uveitis (with prospective applications in early diagnosis).

Purpose: To evaluate the results of laser corneal confocal microscopy (CCM) in viral uveitis of varying localization.

Material And Methods: The main study group included 23 patients (23 eyes) diagnosed with unilateral herpesviral uveitis (chorioretinitis), the patients' age varied from 18 to 79 years.

[Ocular thrombotic microangiopathy in atypical hemolytic-uremic syndrome (a clinical case study)].

The article presents a clinical observation of ocular thrombotic microangiopathy in atypical hemolytic-uremic syndrome - a rare genetic disease characterized by systemic thrombosis caused by uncontrolled activation of alternative complement pathway. A typical manifestation of this ocular lesion in this disease is bilateral Purtscher-like retinopathy. Timely diagnostics of atypical hemolytic-uremic syndrome, including ophthalmologic examination, determines the early start of a highly effective pathogenetic therapy with complement inhibitor eculizumab.

[Electrophysiological studies of the retina in antiphospholipid syndrome].

Aim: to evaluate the functional state of the retina in patients with antiphospholipid syndrome (APS) through different types of electroretinography (ERG).

Material And Methods: The total ERG (t-ERG), local macular ERG (m-ERG), and oscillatory potentials (OP) were recorded in 56 patients with verified APS.

Results: In most patients with APS, ERG was of abnormal appearance, particularly, t-ERG was notable for reliably lower a- and b-wave amplitudes (70% of cases), m-ERG - for lower amplitudes and shorter latency (64% of cases).
