[Viral conjunctivitis as the first sign of COVID-19 infection (clinical observation)]. / Virusnyi kon"yunktivit kak pervyi priznak koronavirusnoi infektsii COVID-19 (klinicheskoe nablyudenie).

The article presents a case of complicated viral conjunctivitis. Conjunctivitis was the initial sign of the new coronavirus infection (COVID-19) in the patient. The disease had a fairly long course and led to symmetrical scarring in the form of partial external symblepharon and dry eye syndrome. Ophthalmologists should be aware about this disease and its complications. Early treatment with corticosteroids in combination with symptomatic therapy can contribute to prevention of the development of conjunctival scarring. In addition to conjunctival scarring, this disease can possibly potentiate the development of keratitis, optic neuritis, and uveitis.

[Use of macular lenses in patients with age-related macular degeneration]. / Primenenie «makulyarnykh¼ linz pri vozrastnykh degenerativnykh izmeneniyakh setchatki.

The review presents the characteristics and results of clinical studies on implantation of different types of macular lenses (IOL-VIP system, Lipschitz Macular Implant (LMI), Fresnel Prism Intraocular, IOL AMD) installed in the capsular bag after phacoemulsification in patients with age-related macular degeneration (AMD). The literature review shows that up to now, the data on implantation of these lenses was contradictory and generally based only on short-term results. There are quite strict criteria for the selection of patients to evaluate the maximum possible postoperative visual rehabilitation of patients using special programs, the effectiveness of which largely depends on their commitment to postoperative, sometimes long-term treatment. Additional independent clinical studies with longer follow-up periods for patients with AMD are required to determine the efficacy and safety of macular lenses in order to recommend their use in wide clinical practice.

[Results of fistulizing and Ahmed valve surgery for treatment of refractory glaucoma].

Surgical results of 76 patients (76 eyes) aged 25-79 years with secondary refractory glaucoma were analyzed. The best hypotensive effect and visual functions integrity were achieved with Ahmed valve implantation (86.7% and 83.3% of cases respectively); after conventional fistulizing surgery the hypotensive effect was observed in 45.5%, noncompromised vision--in 54.5% of cases. Tunnel trabeculectomy with iridocycloretraction led to normalization of intraocular pressure and stabilization of visual functions in 81.3% and 68.8% of cases respectively and thus can be considered as an alternative to fistulizing surgery in patients with secondary refractory glaucoma. Uveal glaucoma is a relative contraindication to Ahmed valve implantation, while neovascular glaucoma is that to tunnel trabeculectomy with iridocycloretraction.

[Anti-VEGF-agents in treatment of neovascular glaucoma].

Neovascular glaucoma (NVG) is one of the most severe form of refractory glaucoma. Vascular endothelial growth factor (VEGF) is one of the strongest promoters of angiogenesis and was found to be the main neovascularization regulator. The use of anti-VEGF-agents is a rational option because in the majority of cases it allows to reach disappearance or reduction of neovascularization, that significantly reduces the risk of complications in following surgery or laser treatment of NVG.

[Study of the effectiveness of ultraviolet irradiation of blood in the treatment of traumatic uveitis]. / Izuchenie éffektivnosti ul'trafioletovogo oblucheniia autokrovi v lechenii travmaticheskikh uveitov.

Sixty-five patients (65 eyes) with traumatic uveitis were treated. Ultraviolet irradiation of autoblood was included in therapeutic complexes of 28 patients. 37 patients received traditional therapy (corticosteroids, nonsteroid inflammatory agents, etc.). Addition of UV exposure of autoblood to combined therapy for traumatic uveitis more effectively (92.9 vs. 75.7%) and sooner liquidated posttraumatic inflammatory reaction (8.10 +/- 1.5 vs. 12.7 +/- 1.7 days), decreased the hospital stay (11.0 +/- 2.0 vs. 15.8 +/- 1.3 days), and eventually more often improved the visual acuity (in 42.9 vs. 24.3% patients). Hence, UV exposure of autoblood is an effective, safe, and virtually atraumatic method of treatment.
