Summary:

The purpose of the study is to analyze clinical and functional treatment outcomes and usefulness of visual rehabilitation in patients implanted with IOL Lentis Comfort. Material and Methods. 64 patients were examined. Patients of group one underwent cataract phacoemulsification with IOL Lentis Comfort implantation, patients of group two were implanted with IOL Acrysof Restor. Non-corrected and corrected distance visual acuity, for intermediate distance (70 sm) and near visual acuity (30-40 sm) were examined on the 2nd day, in a month and in 6 months postoperatively. In 6 months after surgery subjective assessment of patients' satisfaction with the quality of vision was conducted using a questionnaire. Results. High distance visual acuity was revealed in both groups, visual acuity for intermediate distance was significantly higher in patients of group one, near visual acuity was higher in patients of group two. According to the questionnaire results patients of both groups did not experience difficulties in working and driving during the day, at night, patients of group two were much more likely to report difficulties in driving a car and undesirable light phenomena. Conclusion. Implantation of IOL with low-addition power and asymmetric optics provides high quality vision at various distances. The low level of undesirable light phenomena contributes to rapid adaptation of patients in the postoperative period.

Retina and optic nerve characteristics in fellow eyes of patients with epiretinal fibrosis after retinal detachment

Heading: Ophtalmology Article type: Original article

Summary:

The purpose of the study was to examine the relation between the state of macular area and optic disc in fellow eyes of patients after rhegmatogenous retinal detachment (RRD) and the development of epiretinal fibrosis in association with silicone tamponade. Material and Methods. The study included 18 patients operated on for RRD using vitreous cavity tamponade by silicone oil. The examination was performed by means of optical coherence tomography-angiography for fellow eyes of patients. Results. Analysis of retinal thickness and volume revealed that the indices were lower in the group with epiretinal fibrosis. When assessing relative vascular density, area and perimeter of foveal avascular zone (FAZ) the indices were prevailed in the group with epiretinal fibrosis. Conclusion. The study revealed a significant decrease in retinal thickness in the fovea of fellow eyes in patients with epiretinal macular fibrosis. A statistically significant decrease in the thickness of the reticular membranes is revealed in patients with epiretinal macular fibrosis. A statistically significant enlargement of the area and an increase in the perimeter of FAZ, an increase in the relative vascular density in the foveal and deep plexuses in the fellow eyes of patients with epiretinal macular fibrosis were revealed as well.

Informativity of microperimetry in retinal pathology diagnosis

Year: 2020, volume 16 Issue: №1 Pages: 249-253

Summary:

The purpose of the study is to estimate the functional status of central retinal zone with microperimetry method in patients with retinal pathology. Material and Methods. Microperimetry was performed on 16 patients (18 eyes) with different kinds of retinal pathology including thrombosis of central retinal vein branches, age-related macular degeneration, myopic maculopathy, lamellar macular hole, tapetoretinal degeneration, ocular albinism, central serous chorireti-nopathy, proliferative diabetic retinopathy. Mean age was 52.4 years old; male — 8, female — 8. Results. The average light sensitivity of central retinal zone was reduced in the majority of patients. The decrease in the index of retinal light sensitivity in the pattern point corresponding to fixation point did not correspond to the decrease in the best-corrected visual acuity in all cases. Central defects and depression zones topographically corresponded to pathological alterations on the eye fundus. In a patient with ocular albinism fixation was characterized as unstable, in the rest of cases we observed stable fixation. The analysis of fixation allowed receiving additional information about visual quality and the degree of visuomotor coordination in patients with retinal pathology. Conclusion. As a result of the study we showed high informativity of microperimetry for assessing central retinal zone's functional status in retinal pathology.
