The influence of concomitant glaucoma on iol power calculation accuracy
Belov D.F., Nikolaenko V.P.
Abstract

Aim. To estimate the influence of concomitant glaucoma (including that after surgery) on IOL power calculation accuracy before phacoemulsification.

Materials and methods. 413 patients were included in the study divided in 4 groups: 1st – patients with cataract and no concomitant glaucoma (251 cases); 2nd – patients with cataract and primary open-angle glaucoma (POAG) on medical therapy (103 cases); 3rd – patients with cataract and prior trabeculectomy (42 cases); 4th – patients with cataract and primary angle-closure glaucoma (PACG) on medical therapy (17 cases). In all patients, the IOL power calculation was performed using optical biometry (IOL-Master 500). 1 month after surgery, desired refraction according to Barrett Universal II Formula and real obtained refraction estimated by automatic refractometry (Topcon-8800) were compared.

Results. There was no significant difference between study groups 1–3 in IOL power calculation accuracy (the calculation error was –0.09 ± 0.39 D, –0.08 ± 0.45 D, –0.03 ± 0.49 D, for each group respectively). However, we found a higher myopic shift (–0.47 ± 0.48 D, p = 0.095) in the 4th group.

Conclusion. The presence of concomitant POAG on medical therapy, same as earlier trabeculectomy, does not demand any modification of the IOL calculation algorithm. However, in PACG patients we recommend taking –0.5 D lower optical power IOLs to avoid excessive myopic refraction after phacoemulsification.

Estimation of lacrimal dysfunction indices in patients with recurrent pterygium
Bilalov E.N., Yusupov A.F., Nozimov A.E., Oripov O.I.
Abstract

The rationale of the research is driven by the severity of dry eye syndrome (DES) in the pterygium recurrencies development as well as by the necessity to investigate tear dysfunction and methods for its optimal correction in this patient population.

Purpose of the study. To assess the impact of tear dysfunction indices on the development of recurrent pterygium.

Materials and methods. We observed 60 patients (67 eyes) with recurrent pterygium. Patients were divided into four observation groups depending on the number of recurrencies. In order to study the dynamics of the DES manifestations during the postoperative period, pathogenetic therapy was used, which included a tear fluid substitute. All patients underwent a comprehensive assessment of subjective and objective DES indices before and after surgery.

Results. A positive dynamics of subjective manifestations and objective indices of DES under the action of a tear substitute after surgery was reliably confirmed. A decrease in the number of patients with type III and IV crystallization after surgery was confirmed. Conclusion. The obtained data indicate an increase in the mucin content in the tear fluid composition, which leads to a stabilization of the tear film and to a decrease in the DES intensity.

A comparative study of bowman layer transplantation results without and after ultraviolet crosslinking in advanced keratoconus
Oganesyan O.G., Getadaryan V.R., Makarov P.V., Ashikova P.M., Ignatieva N.Y.
Abstract

Aim. A comparative study of Bowman layer transplantation (BLT) after its ultraviolet (UV) crosslinking and BLT without preliminary UV crosslinking in patients with advanced keratoconus (KC) stages III to IV.

Materials and methods. There were 30 patients aged 14 to 37 years with KC III–IV stages. The first group included 15 patients who underwent BLT without prior UV crosslinking. The second group included 15 patients who underwent BLT after UV crosslinking. The criteria for inclusion of patients in the study were: progressive KC, with corneal thinnest point (CTP) without epithelium of 400 μm or less, a maximum keratometric index (Kmax) of 58 D and more, with patient satisfied by his visual acuity in a scleral contact lens (SCL) and refusing keratoplasty.

Results. In comparison with preoperative data in both groups, Kmax decreased by an average 0.6 ± 0.5 D, and CTP increased in the first group by an average of 41.5 ± 16.3 µm, and in the second group by an average of 31,9 ± 9.2 μm. Best corrected visual acuity (BCVA) did not change.

Conclusion. During the follow-up of 26.6 ± 6.2 (from 6 to 36) months, CTP and Kmax indices remained stable in operated patients, which indicates the arrest of KC progression after BLT with crosslinking and without it. The preservation of endothelial cell density and BCVA values indicates the safety of both methods.

Dynamics of vitreoretinal interface changes in diabetic macular edema during regular antiangiogenic therapy
Oskanov D.H., Sosnovskii S.V., Boiko E.V., Berezin R.D., Kotsur T.V.
Abstract

In the study, the state of the vitreoretinal interface (VRI) was investigated in diabetic macular edema (DME) at primary diagnosis and during regular antiangiogenic ranibizumab therapy. At primary diagnosis, pathological VRI changes were detected in 49.3% of cases. During regular antiangiogenic therapy, the transformation of initially normal VRI into pathological one occurs in 6% of cases, the transformation of initially pathological VRI into normal or other pathological one – in 15.8%. Initially pathological VRI is not an absolute indication for vitrectomy, since in no fewer than 7.9% of cases its transformation into normal VRI is possible.

Cataract surgery in pseudoexfoliation syndrome
Potyomkin V.V., Goltsman E.V.
Abstract

Phacoemulsification is a main method of cataract surgery. The presence of pseudoexfoliation syndrome (PEX) may involve the procedure in difficulty and contribute to development of intra- and postoperative complications.

Purpose. To assess the effect of PEX on phacoemulsification.

Materials and methods. 1010 patients (580 with PEX and 430 without PEX) admitted for cataract surgery, underwent phacoemulsification with implantation of various IOL types. An analysis of main phacoemulsification parameters was carried out: cumulative dissipated energy (CDE), aspirated BSS amount, time of surgery. The prevalence of some possible intraoperative complications was assessed: descemet membrane detachment, posterior capsule rupture, retrolental lens material, and zonular dialysis.

Results. In patients with PEХ, local descemet membrane detachment and retrolental lens material were significantly more common, at the same time CDE was higher.

Conclusion. When planning phacoemulsification, patients with PEX require more thorough preoperative examination, higher alertness during surgery and longer follow-up in the postoperative period.

Telemedicine in ophthalmology. Part 1. “Common teleophthalmology”
Astakhov Y.S., Turgel V.A.
Abstract

Telemedicine (TM) is one of the fastest growing segments of healthcare and medical business in the world. In a broad sense, TM means the use of the most modern data technologies in distant medical care practice. Teleophthalmology (TO) is an important area of TM, it includes several priorities, main of which being remote diagnosis, treatment and management of patients with ophthalmic diseases, in particular, diabetic retinopathy, glaucoma and age-related macular degeneration. The development of TO is conditioned by the need for high-tech specialized medical care for people in remote regions. On the path of introducing TO worldwide and in Russia, a huge number of obstacles exists: obtaining high-quality fundus images, training specialists to work in the TM area , creation of standards for image analysis and transmission, TM implementation into the legal field, ensuring of stable financing, creating positive patients and doctors attitude towards TO. In this part, we provide an overview of TO development trends, as well as ways to solve the problems standing in its way.

Characterization of toxic effects in acute poisoning with methanol and ethanol
Samoylov A.N., Barieva A.M.
Abstract

Toxic damage to the optic nerve is one of the causes of the development of degenerative processes in the fibers of the optic nerve, leading to its atrophy. Exposure to methanol and ethanol is associated with the damaging effects of metabolites, which lead to ATP deficiency. Knowledge and understanding of pathogenetic processes can help the doctor to make a timely diagnosis, which will allow the start of etiopathogenetic therapy as early as possible. The prognosis for acute poisoning with methanol and ethanol depends not only on the degree of intoxication, but also on the timeliness and accuracy of diagnostic and therapeutic tactics.

Optic neuropathy and exophthalmos edematous: symptom or complication?
Brovkina A.F.
Abstract

The article is concentrated on the mechanism of the development of optic neuropathy in patients with edematous proptosis – one of the clinical forms of endocrine ophthalmopathy. All probable options for the pathogenesis of optic neuropathy are reviewed in detail: increased intraorbital pressure, compression of the optic nerve by enlarged extraocular muscles, the formation of the apical syndrome with compression of the optic nerve in the zone of the Zinn’s ring, an increase in the volume of orbital fat, tension of the optic nerve by an anteriorly shifted eye (exophthalmos), and arterial blood flow impairment in the ophthalmic artery, impaired venous blood flow in the orbit. Based on 103 follow-ups of patients with edematous proptosis and optic neuropathy (68 of them had initial optical neuropathy), the author offers her concept of the pathogenesis of optic neuropathy in patients with sub- and decompensated edematous proptosis, considering optic neuropathy as a complication of endocrine ophthalmopathy. The signs of optical neuropathy in the initial stage of its development are conceived.

The influence of the locomotor stump’s form on the ocular prosthetics result with different methods of eye removal
Baranova N.A., Senina I.A., Nikolaenko V.P.
Abstract

Aim. To determine the optimal shape of the locomotor stump and the configuration of the corresponding ocular prosthesis, ensuring their maximum motility in patients with anophthalmia with different methods of eye removal.

Materials and methods. The study group consisted of 132 patients aged 18–80 years after enucleation or evisceration. Examination methods included medical history; examination of eyelids, measurement of length and width of the palpebral fissure, as well as of the depth of conjunctival fornices on both sides; assessment of the volume, shape, surface topography, position and excursions of the locomotor stump, of the protrusion of the ocular prosthesis compared to the contralateral eye; photo registration of the studied parameters.

Results. During the study, there were 3 types of locomotor stump identified: moderate with retraction in the upper third; voluminous flattened; voluminous hemispherical. The locomotor stump after enucleation was voluminous flattened or moderate with retraction in the upper third. The best motility of the locomotor stump was noted nasally and downward. The motility of the ocular prosthesis was 47.4% compared to the contralateral eye. The locomotor stump after evisceration with keratectomy was voluminous hemispherical or voluminous flattened. Its motility in all four directions was about the same. The motility of the ocular prosthesis in comparison to the contralateral eye was 55.9%. The locomotor stump after evisceration without keratectomy was voluminous hemispherical, uniform, smooth. The motility of the locomotor stump was maximal in comparison to other groups and relatively equal in all four directions. The motility of the ocular prosthesis in comparison to the contralateral eye was 68.2%.

Conclusion. The optimal shape of the locomotor stump, providing the greatest motility of the ocular prosthesis is voluminous hemispherical. The same protrusion of the eyeball and that of the cosmetic prosthesis relatively to the frontal plane after enucleation is achieved by increasing the thickness of the prosthesis itself, which reduces its motility. Evisceration with implantation of the orbital prosthesis involves the use of a thin-walled ocular prosthesis, the back surface of which ideally repeats the locomotor stump surface and does not prevent its maximum motility. When removing a squinting eyeball with preserved corneal diameter, a smaller implant should be used to prevent excessive opening of the palpebral fissure, or to prefer evisceration with keratectomy.

Von Hippel–Lindau disease with concomitant Hodgkin’s disease and congenital hypertrophy of the retinal pigment epithelium
Rakitsky A.V., Shakhnazarova A.A., Shcherba M.A.
Abstract

The article presents a rare case of combination of von Hippel–Lindau disease and Hodgkin’s disease. The disease began with neurological symptoms with gradual progression over the next 3 years. The diagnosis of von Hippel–Lindau disease was made after MRI of brain and spinal cord, abdominal MICTs, and detection of brain stem and spinal cord tumors, multiple pancreatic cysts. We performed resection trepanation of the posterior cranial fossa and microsurgical total removal of hemangioblastoma of the medulla oblongata. After 1.5 years the patient is diagnosed with Hodgkin’s disease and several courses of chemotherapy are carried out, reaching full remission, confirmed by PET with CT. 14 months later, the patient consulted an ophthalmologist due to visual impairment and floating opacities in her left eye. The ophthalmologic examination for the first time revealed multiple bilateral retinal hemangiomas and vitreal hemorrhages from tractional retinal tears caused by posterior hyaloid detachment and unrelated to hemangiomas in the left eye. The barrier laser coagulation of the left eye retinal tears was performed, and the observation tactics was adopted.

Choroid melanoma, developed from nevus
Stoyukhina A.S., Lerner M.Y.
Abstract

It is known that 25% of choroidal nevus are suspicious, and the risk of their malignanisation is 2-13% with a tendency to increase during follow-up me elongation. It is known that 5.8% undergoes malignancy within 5 years, and 13.9% of suspicious choroidal nevi undergoes malignancy within 10 years. In the article, a clinical case of choroidal melanoma development 5.5 years after the detection of suspicious nevus in a patient who refused to follow up is described. In the presented case, there was a combination of two risk factors of nevus malignisation, which significantly increases the likelihood of such an outcome. Long-term follow-up of patients is required from the first day of diagnosis “nevus of the choroid with signs of progression”.
