microperimetry

Modern view on the problem of optic neuritis (systematic review)

Summary:

The review discusses modern concepts of etiopathogenesis, clinic, diagnosis, treatment and preventive measures for optical neuritis, as well as the position of modern ophthalmology on the principles of management of patients with optical neuritis of various etiologies. The review includes 14 sources over the past 25 years from Russian (Elibrary CyberLeninka) and international (PubMed) databases.

Dynamics of changes of microperimetry parameters of retina by closure of macular hole with preservation of internal limiting membrane

Organization: National Medical and Surgical Center n. a. N. I. Pirogov
Summary:

Objective: To evaluate the medical effectiveness of the macular hole closure (MH) technique, which is based on the limiting of the internal limiting membrane (ILM) peeling. Material and Methods: The results of surgical treatment of 80 patients (80 eyes) diagnosed with MH were analyzed. Patients are divided into two groups: group 1-patients who had a standard peeling; group 2-patients who were operated on using the original method with partial peeling of the macular area. All patients underwent visometry, biomicroscopy, ophthalmoscopy, and OCT-examination. Results: By the 30th day after surgical treatment, a statistically significant excess of light sensitivity parameters was detected in the nasal part of the pattern used: the upper-nasal and lower-nasal quadrants, where peeling was not performed (p=0.032) and (p=0.034), respectively. In the 1st observation group, the recovery of the fixation point was observed during the early and late operating period and at 12 months was 58.3% (p=0.041). In group 2 patients, by the time of 1 month after surgery, the recovery of the fixation point occurred in 88.7%. Conclusion: When conducting the method of limited peeling, the ILM is preserved, which reduces the risk of intraoperative damage to the retina layers. A higher functional result was obtained in comparison with the group where the standard method was used.

Informativity of microperimetry in retinal pathology diagnosis

Year: 2020, volume 16 Issue: №1 Pages: 249-253
Heading: Ophtalmology Article type: Original article

Organization: S. Fyodorov Eye Microsurgery Federal State Institution, Tambov State University n. a. G.R. Derzhavin
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.
