“…In our case, however, OCT images demonstrated that the foveal defect did not change in size or shape even at month 6 compared to day 10. Another case of solar maculopathy has been presented in the atlas by Aznabaev et al [17]. The OCT scans crossing the central fovea displayed a dot-shaped destruction of the IS/OS and photoreceptor outer segment layer with insubstantial deformation of adjacent retinal layers caused by detritus, which is close to our findings [17].…”

Background: Radiation damage to the eye is most commonly caused by sunlight. Solar retinopathy is a form of retinal damage that occurs after exposure to solar radiation, with the most common symptoms being reduced vision and central scotoma. Purpose: To report a case of retinal damage following exposure to reflected sunlight with a favorable outcome. Materials and Methods: The patient underwent visual acuity, tonometry, ophthalmoscopy, optical coherence tomography (OCT), fundus photography and fluorescein angiography. Results: At six months after initiation of treatment, the patient reported that the white spot before his left eye decreased in size, and became transparent and practically unnoticeable to him. In solar retinopathy, the OCT appearance of retinal defect may vary, depending on the severity of damage, but provides evidence of destruction of the outer retinal layers. Conclusion: We reported a case of retinal damage following exposure to reflected sunlight with a favorable outcome. Follow-up OCT showed complete restoration of the affected retinal structures in one eye and the residual changes in the outer photoreceptor layer and RPE in the fellow eye. Therefore, solar retinopathy can occur with OCT evidence of retinal destruction following retinal damage from direct and/or reflected sunlight.

“…Актуальным является поиск новых высокоэнергетических технологий, направленных на уменьшение травматизации, повышение безопасности и эффективности хирургического лечения. Тремя группами ученых было предложено использование низкочастотного ультразвука для превращения стекловидного тела в легкоудаляемую эмульсию [6][7][8][9]. Благодаря увеличению скорости удаления стекловидного тела, достигаемое при помощи увеличения частоты резов, происходит уменьшение времени хирургического вмешательства, также преимуществом является снижение тракционного воздействия и риска ятрогенных осложнение [10]…”

Currently, three groups of scientists are developing the introduction and use of lowfrequency ultrasound in retinal and vitreous surgery. There is not enough data and work to study the effects of this type of energy on the functional activity and structural state of the retina. In this regard, we conducted experimental and diagnostic studies using modern and objective methods. The main purpose of this article is analyzing the parameters of the electroretinogram of the rabbit retina and compare it with histological data after removal of the vitreous body using low-frequency ultrasound and mechanical action. Experiments were conducted on Chinchilla rabbits (n=40). In the experimental group (n=20), vitreous removal was performed using low-frequency ultrasound, in the control group (n=20) using a guillotine mechanism. On the 1st, 7th, 14th and 14th days, the parameters of the a- and b-waves of the electroretinogram were recorded. The structural state of the retina was also evaluated on histological sections. On the 1st day after surgery in both study groups there was a decrease in all parameters of the electroretinogram, the evaluation of histological data showed the presence of edema in most layers of the retina. On days 7 and 14, the parameters of the a- and b-waves were restored, but did not return to normal in both groups, a decrease in edema in all layers of the retina was observed on histological preparations. On day 30, the a- and b-wave indicators returned to normal, which indicates the restoration of the functional properties of photoreceptor cells, bipolar and Muller cells in both groups, the retinal layers were clearly visualized on histological sections without signs of edema. Analysis of electroretinogram parameters and histological data showed that the use of low-frequency ultrasound for vitreous removal can be considered safe and promising for further development.
