“…Спустя 1 месяц в группе с панретинальной фотокоагуляцией наблюдалось значительное увеличение размера зрачка, а в группе с фокусной фотокоагуляцией значительного изменения не зафиксировано. С помощью автоматизированной инфракрасной пупиллометрии удалось продемонстрировать, что панретинальная фотокоагуляция сетчатки может значительно влиять на изменение размера зрачка, в то время как фокусная фотокоагуляция сетчатки особого влияния не оказывает [9].

Nowadays medicine has great opportunities for a detailed study of organs and systems, quick and accurate diagnosis of norm or pathology. Many diagnostic procedures are universal and are used by doctors of different specialties. Pupillography is a method of studying pupillary reactions, which is based on registering changes in its magnitude by photographing or filming. This study has found wide application in many areas of medicine, such as ophthalmology, neurology, narcology, general medical practice, for the diagnosis of different pathological conditions.Currently, in all areas of medicine, preference is given to objective diagnostic methods. In our country, much attention is paid to the development and introduction into medical practice of new technologies and minimally invasive research methods which purpose is timely accurate diagnosis and effective treatment of various diseases. The visual analyzer transmits visual information to the center of the parasympathetic division of the autonomic nervous system, which is responsible for the work of the sphincter of the pupil and to the center of the sympathetic division, which is responsible for the work of the dilatator. In the pathology of the visual organ, there is a violation of the correctness of information transmission, which can be used for basic research not only in ophthalmology but also in other specialties. Science and technology provides opportunities for ultra-thin, specific diagnostics and monitoring of various physiological and pathological states of organs and systems, the results of which are taken into account in many analyzing programs of the latest devices. Therefore, the importance of studying pupillary reactions is of great interest for many areas of medicine, and more specific studies can improve the accuracy of the diagnosis. This article describes the history of the development of pupillometric and pupillographic methods of research from the middle of the XVIII century and till modern devices. The importance of the study of pupillary reflexes for assessing the state of the visual analyzer and the possibility of using chromatic pupillometry is discussed, the main indicators of the pupillomotor system and their norms are given. Pupillometry provides the ability to accurately quantify changes in pupil size for clinical and research purposes.

“…They concluded that conventional laser treatment caused more intense laser burns compared to the PASCAL laser and caused more damage to the ciliary nerves. In another study by Yilmaz et al, 21 in which patients with diabetic retinopathy who underwent panretinal photocoagulation and focal laser photocoagulation were assessed with automated infrared pupillometry; it was reported that the panretinal photocoagulation group had significantly increased basal measurements of pupil diameters in all lighting conditions, while there was no significant change in the focal laser photocoagulation group. Although there are studies in the literature which examine the effects of laser photocoagulation on pupil diameter, there is lack of evidence on dynamic pupil responses in eyes with retinal vein occlusion that underwent retinal laser photocoagulation.…”

Purpose: This study aims to evaluate the pupillary light reflex measured with dynamic pupillometry in patients who underwent retinal laser photocoagulation due to unilateral retinal vein occlusion (RVO). Methods: A total of 48 patients with unilateral RVO were included in the study. Thirty-four patients had undergone retinal laser photocoagulation while the remaining 14 patients that did not undergo laser treatment were observed for control purposes. Of the laser-treated eyes, 14 eyes (41.2%) had central RVO (CRVO) and 20 eyes (58.8%) had branch RVO (BRVO). Among the 14 patients with RVO without laser treatment, nine eyes (64.3%) had CRVO and five eyes (35.7%) had BRVO. Pupillary light reflexes were assessed with dynamic pupillometry (MonPackOne®; Metrovision, France). The parameters of the eyes with RVO were compared with that of fellow healthy eyes. Results: Mean patient age was 65.8 ± 10.4 years and median time after photocoagulation was 25.5 months. Eyes that received laser photocoagulation had lower pupil contraction amplitude ( p = 0.037), prolonged contraction latency ( p = 0.027), slower contraction velocity ( p = 0.043), and slower dilation velocity ( p < 0.001) compared to healthy fellow eyes. Subgroup analysis revealed that eyes with CRVO had lower contraction amplitude ( p = 0.013) and slower dilation velocity ( p = 0.003), and eyes with BRVO had slower dilation velocity ( p = 0.003). Non-laser-treated eyes with RVO revealed no significant difference in any of the pupillary light reflex parameters compared to fellow eyes. Conclusion: Laser-treated eyes with RVO demonstrated changes in pupillary light reflex parameters including reduced contraction amplitude, prolonged contraction latency, and slower contraction and dilation velocities measured with dynamic pupillometry.

Changes in Pupil Size Following Panretinal and Focal/Grid Retinal Photocoagulation: Automatic Infrared Pupillometry Study

Abstract: We have demonstrated through automated infrared pupillary measurements that panretinal laser photocoagulation may significantly influence pupil size and focal/grid laser photocoagulation may not.
