Sympathetic Nerve-Mediated Fellow Eye Pain During Sequential Cataract Surgery by Regulating Granulocyte Colony Stimulating Factor CSF3. Front Cell Neurosci 2022; 16:841733.

Abstract
Patients were found to experience more pain during their second eye cataract surgery compared with their first eye surgery. This study aimed to explore the inflammatory alterations along time in the fellow eye after the first eye surgery and to reveal the underlying mechanism. Eighty patients with bilateral cataracts were recruited and were divided into four groups based on the time of having the second eye surgery. The second eye aqueous humor samples were collected just before surgery and analyzed by mass spectrometry and PCR array. Cytokine activity was enriched in the aqueous humor of the contralateral eye with granulocyte colony-stimulating factor CSF3 significantly upregulated at both gene and protein levels. Rabbits with or without superior cervical ganglionectomy (SCGx) were subjected to lensectomy to mimic human situations. In both human and rabbit models, the fellow eye CSF3 peaked at 1 week post the first eye surgery. Consistently, more neutrophils were recruited to the contralateral eye aqueous humor. Corneal sensitivity and trigeminal electrophysiology were recorded to imply the pain severity in rats receiving capsulorrhexis with or without SCGx. A more intense pulse was detected in the contralateral trigeminal ganglion after the rat received one eye surgery. SCGx could effectively reduce the fellow corneal sensitivity and trigeminal nerve pain. These alterations were under direct regulation of the sympathetic nerves on the surgical eye side. Our results suggest that CSF3 and sympathetic activity could serve as potential analgesic targets during ocular surgeries.

Feelings, preoperative anxiety, and need for information in patients undergoing intravitreal injections. Graefes Arch Clin Exp Ophthalmol 2020; 258:1395-1403. [PMID: 32346786 DOI: 10.1007/s00417-020-04699-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/04/2020] [Accepted: 04/09/2020] [Indexed: 10/24/2022] Open
Abstract
PURPOSE To assess feelings, preoperative anxiety, and need for information in patients undergoing intravitreal injections (IVI). METHODS An observational cross-sectional study was conducted in our tertiary university care center between December 2017 and December 2018. Consecutive patients undergoing IVI were included. A paper survey was completed before and after IVI to assess patient experience. Preoperative anxiety and need for information were assessed using the Amsterdam Preoperative Anxiety Information Scale (APAIS) score. RESULTS Hundred patients with a median age of 76.5 years (42-95, SD = 10.1) were included. Median best-corrected visual acuity (BCVA) in both eyes was 0.4 logMAR. Main IVI indications were wet age-related macular degeneration (n = 58), diabetic macular edema (n = 19), and venous occlusion (n = 16). The IVI most unpleasant steps were as follows: using an eyelid retractor, needle entry, changing of physician from one IVI to another, the pre-IVI waiting time, and the high number of IVI required for disease control. Preoperative anxiety (APAIS score ≥ 11) was correlated in the multivariate analysis with the need for information (p = 0.004), changing of ophthalmologist between different IVI sessions (p = 0.006), and pain expected before the IVI (p = 0.010). The need for information (APAIS score ≥ 5) was only associated with the preoperative anxiety in the multivariate analysis (p = 0.001). CONCLUSION Preoperative anxiety and need for information are common in patients undergoing IVI even after many IVI. Being injected by different practitioners was strongly correlated with preoperative anxiety and should be avoided as much as possible. Better educational and information programs are needed.

Pain Perception and Acceptance of Illness in Patients Undergoing Phacoemulsification Cataract Surgery under Drip Anesthesia. J Clin Med 2019; 8:jcm8101575. [PMID: 31581551 PMCID: PMC6832406 DOI: 10.3390/jcm8101575] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2019] [Revised: 09/17/2019] [Accepted: 09/26/2019] [Indexed: 02/06/2023] Open
Abstract
For many years, cataracts have been the main cause of vision loss and vision impairments in the world (43% and 33%, respectively). Currently, the most common surgical method for treating cataracts is phacoemulsification. The aim of this study was to assess the pain perception and acceptance of illness connected with awaiting phacoemulsification cataract surgery under intravenous drip anesthesia, as well as to determine the effect of selected sociodemographic factors on the above. Methods: The study was conducted in a group of patients of the Department of Ophthalmology, University Clinical Hospital in Białystok, Poland suffering from cataracts, who underwent phacoemulsification surgery under intravenous drip anesthesia. The study group consisted of 151 people. The study used an original short questionnaire and three standardized psychometric scales: The acceptance of illness scale (AIS), the Beliefs about Pain Control Questionnaire (BPCQ), and the Coping Strategies Questionnaire (CSQ). Results: The median overall AIS point value was 24 points, which is considered an average score in terms of disease acceptance. Respondents assessed the influence of individual factors on the level of perceived pain and the impact of individual strategies for coping with pain similarly. The level of perceived pain decreased with the patient’s age. People with a higher education level experienced a greater level of pain; however, this relationship was not statistically significant. The place of residence did not affect the level of pain experienced during the procedure. Women had a greater level of acceptance of illness. The respondents’ education level negligibly differentiated the approach to the disease. The place of residence also did not affect the assessment of illness acceptance as measured by the AIS. Whether the surgery pertained to the first or second eye did not significantly affect the approach to the disease. Conclusions: The level of acceptance of illness and pain perception were at a moderate level among the patients. The acceptance of illness was significantly influenced by the age of patients and the waiting period for phacoemulsification, and this level of acceptance decreased significantly with the increasing age of patients. The longer the waiting period for surgery, the lower the acceptance of illness. Sex significantly differentiated the level of pain experienced during the procedure. Education and place of residence did not significantly affect the acceptance of illness and the feeling of pain.
