Evaluation of the functional effect of surgical treatment of rhegmatogenous detachment in the late postoperative period

Purpose: to identify the key factors determining the functional outcome of surgical treatment of rhegmatogenous retinal detachment. Material and Methods. The study group included 39 patients operated for rhegmatogenous retinal detachment, which 6 months after surgery were divided into 2 groups depending on visual acuity obtained. All patients underwent standard ophthalmologic examination and color computed perimetry, electrophysiological studies, electro-retinography and registration of visual evoked potentials, optical coherent tomography, color Doppler mapping of posterior pole vessels. Results. 6 months after the surgical treatment of retinal detachment in the 1st group, best corrected monocular visual acuity increased by 4 times in comparison with the 2nd group. When analyzing color-opponent perimetry results in patients of the frst group, a threefold improvement in medium sensitivity and reliability factor indices for both red and blue stimuli was detected in comparison with the 2nd group. Patients in the 2nd group showed an increase in the phosphene index. In patients of this group in late postoperative period there was an increase in peripheral resistance of vascular wall in both arterial and venous parts of the blood fow, which was probably one of important reasons for non-recovery of vision in patients of this group. Conclusion. Full restoration of regional blood fow and receptor channels of organ of vision, as well as restoration of local and general electrical sensitivity of retina and visual pathway conductivity, is a necessary component of successful restoration of visual functions.
