Frequency of vitreoretinal adhesion in retinal vessels in patients with axial myopia of different age groups

Abstract

Purpose. Finding out the frequency and structures posterior vitreous detachment (PVD), the proportion of local vitreoretinal adhesion in topographical zones of large retinal vessels of posterior pole of the eye in patients of different age groups with axial myopia.Material and methods. Clinical material was 82 eyes (41 patients). The age of patients ranged from 18 to 70 years. According to the age category, which is determined by the WHO classification, all patients were divided into 3 groups. The 1st group (18-44 years old) included 12 people (24 eyes); the 2nd group (45–59 years old) included 14 people (28 eyes); the 3rd group (60–74 years old) included 15 people (30 eyes).Results. In the 1st group PVD was not detected in 11 eyes (45.8%); in 13 eyes there were various variants of PVD (54.2%). In the 2nd group PVD was not detected in 9 eyes (32.1%); in 19 eyes there were various variants of PVD (67.9%). In the 3rd group PVD was not detected in 5 eyes (16.7%); in 25 eyes (83.3%) there were various variants of PVD. In this group, there was statistically significant predominance of partial PVD with fixation of the posterior hyaloid membrane to inner limiting membrane (PHM to ILM).Conclusion. In the group of elderly patients with axial myopia (60– 75 years), statistically significant increase in incidence of local adhesion of PHM to ILM in the projection of large retinal vessels was revealed in comparison with young and middle-aged groups (10 cases versus 1 and 2, respectively, p<0.05). This feature must be taken in examination and subsequent management of these patients.
