Predominantly classic CNV has more high treatment density, then occult CNV. In cases of occult CNV are necessary more injections. The results of treatment are worse if patient non-observance recommendation. Absence of state support in respect to patient with exudative AMD is negative factor in functional results of treatment, especially in cases of occult CNV. Key words: choroid neovascularization, subretinal neovascular membrane, angiogenesis inhibitor, age-related macular degeneration, fibrovascular detachment of pigmental epithelium.
Fayzrakhmanov R.R., Bikbov M.M., Yarmukhametova A.L. RETINA CENTRAL PART CHANGE AT SPONGY DIABETIC MACULAR EDEMA ACCORDING TO OPTICAL COHERENT TOMOGRAPHY DATA There is a spongy retinal swelling of 48% in the whole diabetic macular edema. The study found that if patient has the spongy macular edema, there is pathological damage in the outer nuclear layer of the retina, the outer plexiform, retinal pigment epithelium, which determines the change in the total profile of the macular area.Key words: edema, diabetes, retina.
Khalimov A.R. OPHTHALMOLOGICAL SOLUTION FOR CORNEAL COLLAGEN CROSSLINKING WITH RIBOFLAVIN AND CHITOSAN The article provides information about the clinical use of ophthalmic solution for corneal collagen cross-linking by riboflavin and chitosan. Riboflavin and chitosan ophthalmic solution for cross-linking is accelerating regeneration of the cornea epithelium.Key words: cross-linking, keratoconus, chitosan.
Chashchin G. V., Ponomarev V. O., Nosov S. V., Barybin A.S. NEW INORGANIC FLUOROFOR AND PHOTOSENSITIVE RETINAL-CONTAINING PROTEINS AS A BASIS OF ELEMENT BASE FOR QUANTUM NANOSURGERY OF EYE RETINA Possibility of restoration of sight at dystrophic defeats of a retina by introduction of quantum dots and their interaction with visual proteins of photoreceptors is discussed.Key words: quantum dots, eye retina, photoreceptors
Shakirov R.F. CHANGES OF THE CORNEA THICKNESS IN KERATOCONUS FOLLOWING PERILIMBAL INJECTION OF DISPERSED ALLOPLANT BIOMATERIALIn the article there are presented the results of the measuring of cornea thickness in keratoconus of different stages before and after perilimbal injection of the dispersed alloplant biomaterial.Key words: dispersed alloplant biomaterial, keratoconus, keratopachimetry
Shunkevitch O.N., MelikhovaI.A., BoriskinaL.N., BalalinS.V. ROLE OF DESCEMETOGONIOPUNCTURE IN NORMALIZATION OF INTRAOCULAR PRESSURE IN CASES OF IOP ELEVATION IN THE EARLY POSTOPERATIVE PERIOD AFTER MICROINVASIVE NON-PENETRATING DEEP SCLERECTOMYThere were analyzed reasons, inducing elevation of intraocular pressure in 49 patients (49 eyes) with primary open-angle glaucoma in 1–3 months following microinvasive non-penetrating deep sclerectomy. A high thickness of trabecular Descemet membrane and presence of hypoechoic contents within the intrascleral space are the main factors leading to worsening of aqueous humor outflow and elevation of IOP in the early postoperative period. Normalization of IOP level basing on findings of ultrasound biometry was achieved in all the patients due to laser Descemetogoniopuncture. Key words: glaucoma, Descemetogoniopuncture.
Shcherbakov D.A., Nuraeva A.B., Musina L.M. INFERIOR ORBIT WALL RECOVERY USING CHONDRAL ALLOGRAFTSWe have proved experimentally what the feasibility of chondral allografts for reimbursement of various defects of the inferior orbit wall. In the clinical part of the study we have developed indications for plate chondral allograft for fractures of the inferior orbital wall type blow-out with prolapse of orbital contents into the maxillary sinus and the combination of connective biomaterials to reconstruct small defects of the inferior orbital wall.Key words: inferior orbit wall, chondral allograft
Shchuko A.G., Chesheyko Ye.Yu., Yuryeva T.N. CRITERIA FOR DIFFERENTIAL DIAGNOSTICS OF FUNCTIONAL ANGULAR BLOCK — LATENT STAGE OF CLOSED-ANGLE GLAUCOMA90 patients with suspected angle-closed glaucoma were examined. Control group consisted of 22 healthy patients without glaucoma, and no serious injuries of eyeball structures. Structural and functional changes in the visual system, characteristic for functional angular block, were revealed. They are significantly different from that of patients with functional angular block. UBM criteria of iridociliary zone structure in patients with functional angular block were determined. Functional angular block is an independent pathological status of visual system and is a latent stage of angle-closed glaucoma.Key words: functional angular block, closed-angle glaucoma, differential diagnostics
Ekgardt V.F. ORBITOTOMIYA IN COMPLEX TREATMENT OF ENDOCRINE OPHTHALMOPATHYThe paper considers different variants of orbitotomy in patients with endocrine ophthalmopathy, defines the indicators for their performance. There was evaluated orbitotomy efficiency from the position of cosmetic and functional result.Key words: endocrine ophthalmopathy, orbitotomy.
Yarmukhametova A.L., Fayzrakhmanov R.R., Valyamov R.L. LASER PHOTOCOAGULATION OF NEOVASCULAR MEMBRANE AT AGE-RELATED MACULAR DEGENERATION WET FORM CONSIDERING MICROPERIMETRY DATA The growth of classic neovascular membrane causes the reducing of light sensitivity up to 0 dB, this allows to determine the localization of neovascular membrane and make laser photocoagulation considering the visual fields loss.Key words: classic neovascular membrane, laser photocoagulation, light sensitivity.
