Long-Term Outcome After Bilateral Descemet Membrane Endothelial Keratoplasty for Fuchs Endothelial Corneal Dystrophy. Cornea 2024; 43:726-733. [PMID: 37702586 DOI: 10.1097/ico.0000000000003379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Accepted: 08/05/2023] [Indexed: 09/14/2023]
Abstract
PURPOSE The aim of this study was to assess the long-term clinical outcome, complications, and graft survival of bilateral Descemet membrane endothelial keratoplasty (DMEK) in patients with Fuchs endothelial corneal dystrophy. METHODS This was a retrospective cohort study of 181 patients (362 eyes) with sequential bilateral DMEK for Fuchs endothelial corneal dystrophy. Clinical outcomes were assessed up to 5 years postoperatively. Outcome measures were best-corrected visual acuity, pachymetry, endothelial cell density, graft survival, and complication rates. RESULTS Contralateral DMEK was performed on average 15 ± 11 months (range: 2-60 months) after the first eye. From 1 until 5 years after DMEK, best-corrected visual acuity, pachymetry, endothelial cell density, and graft survival did not differ between the first and second eyes (all P > 0.05). Graft detachment occurred in 67 eyes (19% [18% first eyes, 19% second eyes], 6% bilateral), graft rejection in 9 eyes (3% [3% first eyes, 2% second eyes], 1% bilateral), glaucoma in 25 eyes (7% [8% first eyes, 6% second eyes], 2% bilateral), and graft failure in 22 eyes (6% [4% first eye, 8% second eye], 2% bilateral). All differences were not significant (all P > 0.05). Five-year graft survival rates were comparable for first and second eyes (0.95 and 0.92, respectively; P = 0.15). CONCLUSIONS Clinical outcomes after bilateral DMEK are similar in both eyes and sustainable in the longer term. Within the first 5 years, the same complication may rarely occur in the contralateral eye.

Investigation of subclinical ocular inflammation in the aqueous humor of patients with myopia following bilateral sequential collamer lens implantation. Transpl Immunol 2024; 85:102052. [PMID: 38750973 DOI: 10.1016/j.trim.2024.102052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 05/08/2024] [Accepted: 05/11/2024] [Indexed: 05/27/2024]
Abstract
BACKGROUND The aqueous humor, a transparent fluid secreted by the ciliary body, supports the lens of the eyeball. In this study, we analyzed the cytokine and chemokine profiles within the aqueous humor of the contralateral eye post-implantation of an implantable collamer lens (ICL) to evaluate potential subclinical inflammation in the second eye subsequent to ICL implantation in the first eye. METHODS Aqueous humor samples were procured from both eyes of 40 patients (totaling 80 eyes) prior to bilateral ICL insertion. Subsequently, a comprehensive statistical analysis was conducted using the Luminex assay to quantify 30 different cytokines in these samples. RESULTS Compared to the first eye, the aqueous humor of the second eye demonstrated decreased concentrations of IFN-γ (P = 0.038), IL-13 (P = 0.027), IL-17/IL-17 A (P = 0.012), and IL-4 (P = 0.025). No significant differences were observed in other cytokine levels between the two groups. Patients were then categorized based on the postoperative rise in intraocular pressure (IOP) in the first eye. The group with elevated IOP displayed elevated levels of EGF in the aqueous humor of the first eye (P = 0.013) and higher levels of PDGF-AB/BB in the aqueous humor of the second eye (P = 0.032) compared to the group with normal IOP. Within the elevated IOP group, the levels of EGF (P = 0.013) and IL-17/IL-17 A (P = 0.016) in the aqueous humor were lower in the second eye than in the first eye. In the normal IOP group, cytokine levels did not differ notably between eyes. CONCLUSION Following sequential ICL implantation, it appears that a protective response may be activated to mitigate subclinical inflammation in the second eye induced by the initial implantation in the first eye. Additionally, the increase in IOP subsequent to surgery in the first eye may correlate with the presence of inflammatory mediators in the aqueous humor.

Abstract
PURPOSE The purpose of this study was to compare the preoperative anxiety, aqueous humor monocyte chemoattractant protein-1 (MCP-1) concentration, intraoperative pain, and degree of cooperation of the first eye implantable collamer lens (ICL) surgery with the second eye surgery, of the 1-day interval group with the 1-week interval group, and to investigate the possible causes of these differences, as well as to determine the appropriate interval between bilateral eye ICL surgeries. METHOD The study was a prospective observational study. A total of 120 patients who underwent bilateral ICL surgery at the Department of Ophthalmology, West China Fourth Hospital, Sichuan University, from July to September 2023, were enrolled. The patients were divided into a 1-day interval group and a 1-week interval group. The ICL surgery was performed on both eyes according to the schedule. Anxiety levels, aqueous humor MCP1, cooperativeness, surgical time, pain and satisfaction, and patients' estimations of the time spent in the operation were recorded for each eye. The patients were instructed to recall the intraoperative pain of the first eye surgery after the operation of the second eye. Statistical analyses (two independent samples t-test,two paired samples t-test, the rank-sum test, the chi-square test, non-parametric test with multiple independent samples) were performed to compare the differences between each score in both eyes and two groups. Furthermore, we examined the relationship between pain levels and the reproductive history of the patients. RESULTS In the 1-day interval group, male/female is 22/52, average age is 25.24±5.00. In the 1-week interval group, male/female is 17/29, average age is 25.39±5.57. There was no statistically significant difference between the two groups. In both groups, patients were less nervous, had significantly more pain, had less surgical satisfaction, had a longer estimated operative time, and had elevated preoperative MCP1 during the second eye operation. In the second eye surgery, the patient's cooperation worsened, but it did not lead to an increase in surgical time. A significant proportion of patients, particularly in the 1-week interval group, recalled experiencing reduced pain during the first eye surgery. The 1-week interval group had a higher difference in all indicators between the bilateral surgeries. In the second eye surgery, patients in the 1-week interval group experienced more severe pain, less cooperation, longer estimated operation duration, and a greater MCP1 than those in the 1-day interval group. CONCLUSION Patients undergoing second eye ICL surgery had decreased nervousness, increased pain, decreased cooperation, and satisfaction, and increased MCP1 compared to the first eye surgery. It is recommended that an interval of about one week should be avoided between bilateral surgeries when developing a surgical schedule to improve patients' cooperation, satisfaction, and comfort.

Abstract
BACKGROUND To explore the changes of cytokines expression in aqueous humor (AH) of eyes of patients with congenital cataract (CC) who underwent delayed sequential bilateral cataract surgery (DSBCS). METHODS 28 patients with CC underwent DSBCS. AH samples were collected from each eye before surgery. The contents of cytokines in AH were detected by Luminex xMAP Technology. RESULTS There was no significant difference in the expression of IL-8, IP-10, MCP-1 and PDGFAA in the AH of the first and second eyes (P = 0.35, 0.39, 0.17, respectively). The level of IL-8 in the first-eye AH was negatively correlated with age (ρ=- 0.519, P = 0.008). IP-10 and MCP-1 in the second-eye AH were negatively correlated with age (ρ=- 0.483, P = 0.009; ρ=- 0.445, P = 0.018,respectively). CONCLUSION The first-eye surgery in patients with CC may not cause the change of cytokines in the contralateral eye. The expression of IL-8, IP-10 and MCP-1 in the AH was negatively correlated with the age of patients. TRIAL REGISTRATION The study was registered at www.chictr.org.cn on March 22, 2022 and the clinical trial number is ChiCTR2200057927.

Abstract
Transforming growth factor-β (TGF-β) is the critical regulator of physiological and pathological conditions in lens. The TGF-β signaling pathway is closely associated with high myopia patients. Thirty eyes from fifteen patients with high myopia who received sequential cataract surgery were enrolled in this prospective study. Ten cataract patients with non-myopia were chosen as a control group. Aqueous humor (AH) samples were used to detect the levels of TGF-β1, TGF-β2, and TGF-β3 in both groups. Compared with the non-myopic cataracts patient group, the highly myopic cataracts group had a significantly higher TGF-β2 (P = 0.019). Besides, the level of TGF-β2 of the second eye was significantly higher than that in the first eye in high myopia cataract patients group (P = 0.037). And TGF-β1 showed significant differences with age and axial length of high myopia cataract patients. Therefore, TGF-β2 may contribute to the development of high myopia and cataract surgery increased the expression of TGF-β2.

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.

Predictability of success and open conjunctival revision rates in the subsequent eye after XEN45 Gel Stent implantation according to lens status. Graefes Arch Clin Exp Ophthalmol 2022; 260:2639-2647. [PMID: 35113249 PMCID: PMC9325854 DOI: 10.1007/s00417-022-05569-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 12/10/2021] [Accepted: 01/14/2022] [Indexed: 11/04/2022] Open
Abstract
PURPOSE To determine the predictability of success and the risk of open conjunctival revision in the subsequent eye after XEN45 Gel Stent implantation according to lens status. METHODS This was a retrospective single-centre study involving 132 eyes of 66 participants who had undergone intraocular pressure (IOP)-lowering XEN45 Gel Stent implantation, either as a standalone procedure in phakic and pseudophakic eyes or in combination with phacoemulsification. Successful surgery was defined by three scores: IOP at follow-up < 21 mmHg (score A) or < 18 mmHg (score B) and an IOP reduction > 20% or IOP ≤ 15 mmHg and an IOP reduction ≥ 40% (score C). In all scores, one open conjunctival revision was allowed, and additional repeat surgery was considered a failure. The predictability of success and revision rate depending on the outcome of the first eye were calculated using Bayes' theorem. RESULTS IOP-lowering did not differ significantly between the first and second eyes. Success rates of standalone surgery in the second eye after successful surgery in the first eye significantly exceed rates after prior failure. For the combined procedure, the rates did not differ significantly. For score A, we determined a 76.6% chance of success following a prior success and a 57.9% chance, if prior surgery failed. The corresponding probabilities were 75% and 59.1% for score B, while 66.7% and 15.7% for score C, respectively. We calculated a 60% risk for revision surgery in the standalone phakic group. If the first eye was not revised, the risk of revision in the subsequent eye was 20%. The corresponding risks were 72.7% and 5% for the standalone procedure in pseudophakic patients and 38.4% and 41.7% for the combined procedure, respectively. CONCLUSION The results of our study offer a tool to predict the outcome of subsequent eye surgeries based on either the outcome in the initial eye and the type of surgery performed, owing to the high predictive potential.

Abstract
BACKGROUND/AIM The aim of this study was to assess the difference in outcome between the first-operated and the second-operated eyes after nonpenetrating deep sclerectomy (DS), and to identify potential success predictors for the second eye. METHODS This single-surgeon, retrospective study analyzed the outcomes of all bilateral nonsimultaneous DS with at least 24 months of follow-up. Its main outcome measure was surgical success, defined as unmedicated intraocular pressure (IOP) ≤15 mm Hg associated with a relative reduction ≥20%. RESULTS In all, 104 eyes of 52 patients who underwent bilateral (standalone or combined) DS, within a mean of 344.3±526.3 days of each other, were analyzed. Postoperatively, the mean medicated IOP decreased from 20.7±7.9 (first-operated eyes) and 19.3±6.6 mm Hg (second-operated eyes) at baseline (P=0.107) to 13.8±4.8 [(-33.3%; P<0.001) first-operated eyes) and 12.7±3.8 mm Hg [(-34.2%; P<0.001) second-operated eyes] after 2 years (P=0.619). Postoperative IOP and treatment reduction, respectively, showed fair (r=0.53) and good (r=0.71) levels of correlation between fellow eyes. The rates of complete success were comparable between first-operated and second-operated eyes (32.7% and 40.4%, respectively; P=0.364). At 2 years, among patients whose first-operated eyes were considered a success, 82.4% of surgeries in second eyes were successful (P=0.001). The odds ratio of a second-operated eye experiencing complete success were 6.32 (P=0.011) if the first-operated eye experienced complete success. CONCLUSIONS The present study demonstrated a strong association between first-operated and second-operated eyes after DS, in terms of surgical outcomes and IOP reduction. In effect, surgical success in the first-operated eye increases the odds of success in the second eye by 6-fold.

Karakahya RH. Do Consecutive Phacoemulsification Surgeries Under Topical Anesthesia Differ in Terms of Pain Perception and Cooperation? Cureus 2021; 13:e19915. [PMID: 34966612 PMCID: PMC8710248 DOI: 10.7759/cureus.19915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/26/2021] [Indexed: 12/02/2022] Open
Abstract
Background Although intraoperative ocular pain has been investigated extensively in the literature, few studies have evaluated the pain perception between consecutive surgeries. Determining the facts about pain perception during phacoemulsification will allow surgeons to decide the type of anesthesia that best fits the patient when planning the contralateral cataract surgery. The aim of this study was to determine the level of pain perception, factors affecting pain perception, level of patient cooperation, and perception of operation time during consecutive phacoemulsification surgeries. Methodology This study included 314 eyes of 157 patients with bilateral senile cataracts who underwent phacoemulsification surgery under topical anesthesia with an interval of no more than six months. All patients underwent complete ophthalmic examination. Operation time, phaco time, surgeon’s comfort, and patient’s cooperation were recorded. Immediately after the operation, the patients graded the pain they experienced via the Visual Analogue Scale (VAS) from 0 to 10 and estimated the operation time. Results The mean VAS score was 0.88 ± 0.97 for the first eye and 1.50 ± 1.27 for the second eye (p < 0.011) surgery. The perception of the mean operation time was significantly lower in the first eye surgery (p < 0.001), even though the real objective operation time and phaco time were lower in the second eye surgery. The surgeon reported significantly more comfort during the first eye surgery. VAS was found to be positively correlated with nonsteroidal anti-inflammatory drug use, intraocular pressure, axial length, anterior chamber depth, central corneal thickness, phaco time, and operation time perception, and inversely correlated with best-corrected visual acuity and mature cataract morphology. Conclusions Consecutive phacoemulsification surgeries appear to differ not only in terms of pain perception but also operation time perception, patient cooperation, and surgeons’ comfort. Determining and controlling the factors that can influence patients’ pain perception and comfort will increase the safety of the contralateral surgery.

Abstract
After the unilateral inflammation or nerve lesion of the ocular surface, the ipsilateral corneal sensory nerve activity is activated and sensitized, evoking ocular discomfort, irritation, and pain referred to the affected eye. Nonetheless, some patients with unilateral ocular inflammation, infection, or surgery also reported discomfort and pain in the contralateral eye. We explored the possibility that such altered sensations in the non-affected eye are due to the changes in their corneal sensory nerve activity in the contralateral, not directly affected eye. To test that hypothesis, we recorded the impulse activity of the corneal mechano- and polymodal nociceptor and cold thermoreceptor nerve terminals in both eyes of guinea pigs, subjected unilaterally to three different experimental conditions (UV-induced photokeratitis, microkeratome corneal surgery, and chronic tear deficiency caused by removal of the main lacrimal gland), and in eyes of naïve animals ex vivo. Overall, after unilateral eye damage, the corneal sensory nerve activity appeared to be also altered in the contralateral eye. Compared with the naïve guinea pigs, animals with unilateral UV-induced mild corneal inflammation, showed on both eyes an inhibition of the spontaneous and stimulus-evoked activity of cold thermoreceptors, and increased activity in nociceptors affecting both the ipsilateral and the contralateral eye. Unilateral microkeratome surgery affected the activity of nociceptors mostly, inducing sensitization in both eyes. The removal of the main lacrimal gland reduced tear volume and increased the cold thermoreceptor activity in both eyes. This is the first direct demonstration that unilateral corneal nerve lesion, especially ocular surface inflammation, functionally affects the activity of the different types of corneal sensory nerves in both the ipsilateral and contralateral eyes. The mechanisms underlying the contralateral affectation of sensory nerves remain to be determined, although available data support the involvement of neuroimmune interactions. The parallel alteration of nerve activity in contralateral eyes has two main implications: a) in the experimental design of both preclinical and clinical studies, where the contralateral eyes cannot be considered as a control; and, b) in the clinical practice, where clinicians must consider the convenience of treating both eyes of patients with unilateral ocular conditions to avoid pain and secondary undesirable effects in the fellow eye.

Correlation between Hyperalgesia and Upregulation of TNF- α and IL-1 β in Aqueous Humor and Blood in Second Eye Phacoemulsification: Clinical and Experimental Investigation. J Immunol Res 2021; 2021:7377685. [PMID: 34485537 PMCID: PMC8413024 DOI: 10.1155/2021/7377685] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 07/12/2021] [Accepted: 08/03/2021] [Indexed: 11/27/2022] Open
Abstract
The aim of this study was to explore the correlation between intraoperative hyperalgesia of the second eye and the dynamic changes of tumor necrosis factor (TNF)-α and interleukin (IL)-1β levels in aqueous humor (AH) of the second eye and whole blood after the first eye cataract surgery. A rabbit model of monocular phacoemulsification was established by administration of 0.3% levofloxacin. Whole blood and AH samples from non-surgical eyes in the experimental group (n =25) and second eye in the blank control group (n =15) were obtained and corneal sensitivity was examined after surgery (1, 3, 7, 14, and 21 days postoperatively). TNF-α and IL-1β levels in AH and TNF-α mRNA and IL-1β mRNA levels in whole blood were measured. In a clinical study, 30 patients who underwent bilateral phacoemulsification within 1 month were divided into six groups in accordance with the operation intervals (1, 3, 7, 10, 14, and 21days). TNF-α and IL-1β levels in AH were measured at the beginning of surgery and intraoperative pain was assessed immediately after surgery. Corneal sensitivity (F =244.910, P <0.05), TNF-α and IL-1β levels in AH (F =184.200, 82.900, P <0.05) of non-surgical eyes and in whole blood (F =272.800, 193.530, P <0.05) in the experimental group were significantly higher than the baseline levels after phacoemulsification. In the clinical study, NRS scores of second eye surgery were higher than those of the first eye(P =0.0025) and 19 (63.3%) patients reported more pain during the second eye surgery. TNF-α and IL-1β concentrations in AH of the second eye were significantly higher than those of the first eye (F =123.60, P <0.05; F =59.60, P <0.05). In conclusion, within 1 month after the first eye phacoemulsification, higher pain sensitivity (hyperalgesia) exists in the second eye, which may be related to dynamic changes in TNF-α, IL-1β levels in AH or whole blood.

Abstract
Purpose We aimed to evaluate activation of conjunctiva-associated lymphoid tissue (CALT) in patients with keratitis using in vivo confocal microscopy (IVCM) and conjunctival impression cytology (CIC). Methods In addition to anterior segment photography and corneal fluorescein staining, IVCM revealed the palpebral conjunctiva in all subjects, and CIC and immunofluorescence staining were performed. Results Diffuse lymphoid tissue cell density in the eyes of patients with keratitis was significantly greater compared with healthy volunteers (P < 0.001). Similar trends were found in perifollicular lymphocyte density (P < 0.001), follicular density (P = 0.029), follicular center reflection intensity (P = 0.011), and follicular area (P < 0.001). Immunofluorescence staining showed that the proportions of CD4+ (61.7% ± 8.0% vs. 17.3% ± 10.2%, respectively, P < 0.001) and CD8+ (46.9% ± 10.0% vs. 19.6% ± 11.5%, respectively, P < 0.001) cells in patients with keratitis was greater compared with healthy volunteers. Interestingly, we also observed changes in the contralateral eye in subjects with keratitis. Conclusions Our research suggests that CALT, as an ocular immune structure, is activated and plays an important role in the pathogenesis of keratitis. This has been overlooked previously. CALT is also active in the contralateral eye of subjects with keratitis.

Abstract
Corneal transparency relies on the precise arrangement and orientation of collagen fibrils, made of mostly Type I and V collagen fibrils and proteoglycans (PGs). PGs are essential for correct collagen fibrillogenesis and maintaining corneal homeostasis. We investigated the spatial and temporal distribution of glycosaminoglycans (GAGs) and PGs after a chemical injury. The chemical composition of chondroitin sulfate (CS)/dermatan sulfate (DS) and heparan sulfate (HS) were characterized in mouse corneas 5 and 14 days after alkali burn (AB), and compared to uninjured corneas. The expression profile and corneal distribution of CS/DSPGs and keratan sulfate (KS) PGs were also analyzed. We found a significant overall increase in CS after AB, with an increase in sulfated forms of CS and a decrease in lesser sulfated forms of CS. Expression of the CSPGs biglycan and versican was increased after AB, while decorin expression was decreased. We also found an increase in KS expression 14 days after AB, with an increase in lumican and mimecan expression, and a decrease in keratocan expression. No significant changes in HS composition were noted after AB. Taken together, our study reveals significant changes in the composition of the extracellular matrix following a corneal chemical injury.

Graefes Arch Clin Exp Ophthalmol 2021; 259:3209-3219. [PMID: 33914156 DOI: 10.1007/s00417-021-05189-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 03/19/2021] [Accepted: 04/07/2021] [Indexed: 11/28/2022] Open
Abstract
PURPOSE The XEN45 Gel Stent is currently the only FDA-approved sub-conjunctival minimally invasive glaucoma surgery (MIGS) procedure. It has been used worldwide either as a standalone implantation procedure or in combination with phacoemulsification surgery. Concomitant phacoemulsification is understood to influence outcomes of traditional subconjunctival filtering surgery. However, the comparative efficacy between standalone XEN45 Gel Sent implantation ("Standalone XEN45") and combined XEN-phacoemulsification surgery ("XEN45-Phaco") remains unclear. This study aims to appraise current literature to compare the efficacy of Standalone XEN45 and XEN45-Phaco in open-angle glaucoma. METHODS A comprehensive search of PubMed, CINAHL, CENTRAL databases was performed with the terms "Xen surgery" followed by selective vetting. Pilot, cohort, observational studies and randomised controlled trials that included at least 10 patients undergoing either Standalone XEN45 or XEN45-Phaco surgeries for the treatment of open-angle glaucoma were deemed eligible for inclusion after independent assessment by 2 authors. The search workflow was reported according to the PRISMA guidelines. Data was pooled using random-effects model. A meta-analysis of continuous outcome and proportions was performed using the meta routine in R v3.2.1. RESULTS Ten studies were included. There was a statistically significant difference in IOP reduction favouring Standalone XEN45 at post-operative day 1, week 1, months 1, 3 and 6. There was a statistically significant difference in decrease in IOP-lowering medications favouring Standalone XEN45 at post-operative week 1 and month 1. CONCLUSION Standalone XEN45 has superior IOP-lowering outcomes compared to XEN45-Phaco in the early post-operative period, up to 6 months after surgery.

Abstract
BACKGROUND Perceived pain during local anesthesia injections can be effected by the injection sequence. OBJECTIVE We sought to compare pain levels during local anesthesia injections during upper lid blepharoplasty (ULB) using 2 surgical sequences. MATERIALS AND METHODS We conducted a prospective, randomized clinical trial. Patients with ULB were randomized to either have local anesthesia injection followed by ULB in the right eyelid and then in the left (Group A) or to have local anesthesia injection to both eyelids followed by ULB on both eyelids (Group B). Pain was assessed using a visual analog scale (VAS) for pain score of 0 to 10. RESULTS Forty patients were included and randomized. The mean VAS score in Group A was 2.60 ± 1.84 and 3.30 ± 1.62 (right and left, respectively, p value = .035). The mean VAS score in Group B was 2.55 ± 1.63 and 2.80 ± 1.67 (right and left eyelids, respectively, p value = .258). No intergroup difference in pain was found. CONCLUSION Patients having sequential anesthesia during ULB perceived more pain on injection to the second eyelid, whereas patients having local anesthesia followed by ULB perceived the same amount of pain in both eyes. Pain levels in both groups were similar. Local anesthesia injections in both groups were well tolerated.

Abstract
Background The purpose of the study was to investigate whether dynamic monocyte chemoattractant protein-1 (MCP-1) level might be as predictors of perceived pain during the first and second phacoemulsification eye surgeries in patients with bilateral cataract. Methods Consecutive bilateral cataract patients undergoing bilateral sequential phacoemulsification were retrospectively enrolled. Patients’ preoperative anxiety score and intraoperative pain score were registered. Aqueous humor samples were obtained during surgery. MCP-1 level in the aqueous humor was measured by enzyme linked immunosorbent assay (Elisa). Patients were assigned to seven subgroups based on the interval between first-eye and second-eye cataract surgery. Comparisons were performed for a subjective sensation and MCP-1 levels among different subgroups. Results pain score during second-eye surgery was significantly higher than during first-eye surgery. Whereas there was no statistical difference in anxiety score between both surgeries. Result from subgroups comparison showed that the visual analog scale (VAS) pain score was statistically greater in 1-group and 6-group during the second eye surgery. Anxiety score did not statistically differ in subgroups. Additionally, the second-eye MCP-1 level was significantly higher at week 1and 6 intervals. Preoperative MCP-1 level was positively correlated with perceiving pain score during both surgeries. Conclusions MCP-1 level in aqueous humor significantly correlated with perceived pain during cataract surgery. Dynamic MCP-1 level could function as predictors of perceived pain during the first and second phacoemulsification eye surgeries in patients with bilateral cataract, which might support clinicians in treatment optimization and clinical decision-making.

Abstract
BACKGROUND To determine whether the outcome of the first eye may serve as a predictor for intraocular pressure (IOP)-lowering effectiveness in the second eye following bilateral ab interno trabeculectomy. METHODS This retrospective single-centre study included 168 eyes from 84 participants, who underwent combined Trabectome surgery with phacoemulsification cataract surgery in a hospital setting. The clinical endpoint was defined as either 'success' or 'failure' based on four separate scores at the longest follow-up time point: IOP at follow-up <21 mm Hg (Score A) or IOP < 18 mm Hg (Score B), without re-surgery and IOP reduction >20%; IOP ≤15 mm Hg without re-surgery and IOP reduction ≥40% (Score C); and the sole absence of re-surgery according to the discretion of the surgeon (Score D). RESULTS No significant difference was observed between the outcomes of first and second eyes. The frequency of success in the second eye after effective surgery in the first eye significantly exceeded that after prior failure. Within our analysis, the probability calculations determined a 75% chance of success following prior success for Score A. If surgery in the first eye failed, the chance of success in the subsequent eye was 37%. The corresponding probabilities were 79% and 32% for Score B, 56% and 9% for Score C, and 99% and 50% for Score D. CONCLUSION The results of our study offer a useful tool to assess the success of subsequent eye surgeries based on the outcome in the initial eye, owing to the high predictive potential.

Abstract
Inherited photoreceptor degenerations are not treatable diseases and a frequent cause of blindness in working ages. In this study we investigate the safety, integration and possible rescue effects of intravitreal and subretinal transplantation of adult human bone-marrow-derived mononuclear stem cells (hBM-MSCs) in two animal models of inherited photoreceptor degeneration, the P23H-1 and the Royal College of Surgeons (RCS) rat. Immunosuppression was started one day before the injection and continued through the study. The hBM-MSCs were injected in the left eyes and the animals were processed 7, 15, 30 or 60 days later. The retinas were cross-sectioned, and L- and S- cones, microglia, astrocytes and Müller cells were immunodetected. Transplantations had no local adverse effects and the CD45+ cells remained for up to 15 days forming clusters in the vitreous and/or a 2–3-cells-thick layer in the subretinal space after intravitreal or subretinal injections, respectively. We did not observe increased photoreceptor survival nor decreased microglial cell numbers in the injected left eyes. However, the injected eyes showed decreased GFAP immunoreactivity. We conclude that intravitreal or subretinal injection of hBM-MSCs in dystrophic P23H-1 and RCS rats causes a decrease in retinal gliosis but does not have photoreceptor neuroprotective effects, at least in the short term. However, this treatment may have a potential therapeutic effect that merits further investigation.

Abstract
Purpose To investigate the change in cytokine microenvironment of the aqueous humor (AH) after surgery in children with congenital or developmental cataracts. Methods AH samples were obtained from 59 eyes diagnosed with a congenital or developmental cataract. Thirty-three of these eyes were aphakic following previous cataract surgery and were scheduled for secondary intraocular lens (IOL) implantation. Additionally, AH samples from 26 eyes that had not undergone surgery were taken. AH samples were then analyzed for 16 different inflammatory immune mediators using multiplex bead immunoassays and enzyme-linked immunosorbent assay (ELISA). Results The mean interval between secondary IOL implantation and original cataract surgery was 24.85 months (range, 9–60 months). Levels of IL-6, IP-10 (CXCL10), MCP-1 (CCL2), and IL-2 were significantly elevated in the AH of eyes after surgery compared to eyes that did not undergo surgery (P < 0.001, P = 0.047, P = 0.006, P = 0.012, respectively). There was significant correlation between the levels of TGF-β2 and intraocular pressure (IOP) in postsurgical and nonsurgical eyes (r = 0.532, P = 0.006; r = 0.57, P = 0.001). Postsurgical outcomes, such as iris adhesions, capsular fibrosis, and capsular contraction, were found not to be significantly associated with cytokine levels in the AH after surgery; however, IL-6 levels in capsular exposure eyes were significantly higher than those in cortical closure eyes (P = 0.023). Conclusions To our knowledge, this is the first study to report significantly increased proinflammatory cytokine levels in the AH after congenital cataract extraction in children. Our study also suggests that this proinflammatory state may be maintained for a prolonged period of time. Overall, these results give us insight into the relationship between the inflammatory cytokine microenvironment of the aqueous humor and potential long-term complications following congenital cataract surgery. Translational Relevance The inflammatory cytokine microenvironment of the aqueous humor might help explain potential long-term complications after surgery in patients with congenital or developmental cataracts.

Gong X, Ren Y, Fang X, Cai J, Song E. Substance P induces sympathetic immune response in the contralateral eye after the first eye cataract surgery in type 2 diabetic patients. BMC Ophthalmol 2020; 20:339. [PMID: 32811461 PMCID: PMC7437040 DOI: 10.1186/s12886-020-01598-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Accepted: 08/05/2020] [Indexed: 12/20/2022] Open
Abstract
Background Substance P (SP) is a nociceptive tachykinin which regulates the immune inflammatory reactions including monocyte chemoattractant protein 1 (MCP-1) production. Sequential second-eye cataract surgery patients often suffer more pain than the first one partly because of the MCP-1 increase in aqueous humor (AH). This study aims to illustrate whether SP is involved in sympathetic inflammatory responses in the contralateral eye in patients with or without type 2 diabetes. Methods This prospective randomized clinical study included 51 cataract patients (22 with diabetes and 29 without). Bilateral sequential cataract surgeries were conducted with 1-day or 1-week interval randomly. More than 100 μl of AH were obtained before surgery and stored for later analysis using magnetic Luminex assays to detect interleukin (IL)-1β, IL-1ra,IL-6, IL-8, IL-10, MCP-1, vascular endothelial growth factor, spinal macrophage inflammatory protein (MIP-1a), interferon-inducible protein 10 (IP-10), regulated on activation, normal T expressed and secreted (RANTES), as well as the enzyme-linked immunosorbent assay for SP. Results Among the 4 groups, no significant differences were found in age, sex distribution, the R/L ration of the first surgery eye, or the lens nucleus hardness (P ≥ 0.802). Over 100 μl of AH samples were collected safely in all cases without intraoperative complications. SP and MCP-1 levels were both increased significantly in the second eye of the diabetic patients with 1-day and 1-week interval (P ≤ 0.040). The SP increase in the second eye of the diabetic patients were significantly higher than that of the patients without diabetes (P ≤ 0.030) both in the groups with 1-day and 1-week interval. Similarly, the MCP-1 increase was significantly higher in the diabetic patients in the group with 1-week interval (P = 0.042). Conclusions Substance P and MCP-1 productions elevated in the AH of the contralateral eye after the first-eye cataract surgery in diabetic patients, indicating that SP and MCP-1 were involved in the sympathetic inflammatory responses. Diabetic patients are susceptible to noninfectious inflammation after cataract surgery, and perceive more pain in the second-eye phacoemulsification.

Abstract
In cataract surgery, it is often found that patients infected hepatitis B virus (HBV) are likely to suffer from more pain than other patients. In order to assess the inflammation status of the aqueous humor in the eyes of cataract patients infected with HBV. RayBio Human Inflammation Array was used to assay aqueous humor samples collected from 14 eyes of patients infected with HBV and 14 eyes of cataract patients without HBV infection (the controls) during the cataract surgery. RayBio Human Quantibody Cutom Array was adopted for the validation of the screened cytokines, with aqueous humor samples collected from 40 eyes of patients infected with HBV and 40 eyes of the controls. A pain questionnaire survey about the surgery was conducted in all patients after operation. The results of questionnaire showed that patients infected with HBV were more likely to have pain during operation. The Human Inflammation Array revealed that the expression levels of monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor α (TNF-α) and tumor necrosis factor β (TNF-β) were very high in HBV infected patients and IL-1ra was much lower in patients infected with HBV (all, P < 0.05). In validation, the Human Quantibody Cutom Array revealed that the expression levels of MCP-1 and TNF-α were high in HBV infected patients with significant difference (all P < 0.05). These results revealed that pain-related inflammatory factors MCP-1 and TNF-α were increased in aqueous humor of cataract patients infected with HBV, which indicates that patients infected with HBV may be more prone to intraoperative pain.

Abstract
Purpose: To assess the differences in cytokine levels in the aqueous humor (AH) of bilateral eyes receiving sequential phacoemulsification and intraocular lens implantation.Methods: The levels of 33 cytokines in AH samples collected from separate single-eye operations of 26 age-related cataract patients who experiencing sequential cataract surgery were compared between the first-eye and second-eye groups.Results: The AH level of transforming growth factor beta 2 (TGF-β2), an immunosuppression regulator, in the second-eye group was significantly higher than that in the first-eye group (p = 0.002). No differences in the concentrations or detection rates of other cytokines were observed between the first- and second-eye groups.Conclusion: During bilateral sequential cataract surgery, the AH of the second eye had a higher level of TGF-β2 but not of proinflammatory cytokines or chemokines compared with those in the first eye, implying a protective mechanism preventing the sympathetic immune reaction induced by the first-eye cataract surgery.

Abstract
Patients with Sturge-Weber syndrome (SWS) are susceptible to ocular complications, and among them, glaucoma is one of the most frequent forms. In current study, we utilized multiplex human cytokine antibody array to simultaneously measure the concentration of 40 cytokines in aqueous humor (AH) of patients with SWS-induced glaucoma (SG), or from patients with senile cataract as controls. Compared with the control group, levels of interleukin (IL)-12p40, macrophage inflammatory protein (MIP)-1d, tumor necrosis factor-alpha (TNF-a), IL-5, IL-7, interleukin-6 receptor (IL-6R), and B lymphocyte chemoattractant (BLC) in AH were significantly higher in SG group. Samples from SG patients displayed significantly lower levels of MIP-1b, IL-6, MIP-1a, and monocyte chemoattractant protein (MCP)-1 than controls. Further analysis showed that IL-7, MIP-1a, TNF-a were positively correlated with intraocular pressure (IOP) in patients with early-onset SG. Moreover, IL-12p40 was negatively correlated with age in patients with SG. These cytokines may make contributions to the immunopathogenesis or progression of glaucoma in patients with SWS.

Abstract
PURPOSE To compare the perceived pain and estimated operative duration among patients undergoing bilateral cataract surgery and to demonstrate correlations with the surgical interval and the demographic and medical characteristics of the patients. METHODS A total of 466 patients with cataract who underwent ocular surgery were included. The patients estimated the perceived operative duration and pain they felt during the operation at two times, immediately after surgery and on the first postoperative day; pain was scored using a visual analog scale ranging from 0 (no pain) to 10 (unbearable pain). Patients undergoing bilateral surgeries were divided into four subgroups based on the interval between the two operations (1, 2, 4, or 6 weeks). The perceived pain score and the estimated operative duration were the primary outcomes. RESULTS The pain scores were higher for the second surgery than for the first surgery both immediately after surgery (P = 0.043) and on the first postoperative day (P = 0.002). The estimated operative duration was longer for the second surgery (P = 0.001). Only patients who underwent the second surgery at an interval of 2 weeks perceived more pain both immediately and 1 day postoperatively (P = 0.002, P = 0.022) and a longer operative duration (P < 0.001). Gender, age, and education level might also influence the pain score. CONCLUSIONS Female patients, patients with a younger age, and patients with higher education level are likely to report more pain. Patients who require bilateral cataract surgery should not undergo the second surgery before an interval of 2 weeks.

Abstract
Purpose: To investigate the aqueous humor growth factor profile in high myopic eyes and analyze the interaction of differentially expressed cytokines.Methods: A case-control study including aqueous humor samples from 36 high myopic patients and 32 controls was conducted. Quantibody® Human Growth Factor Array was used to screen the presence of 40 growth factors in aqueous humor. Expressions of differential growth factors were validated by Bio-Plex ProTM multiplex bead-based immunoassay. Protein-protein interaction (PPI) and gene ontology (GO) analyses were performed.Results: Growth differentiation factor 15 (GDF-15), hepatocyte growth factor (HGF), and platelet-derived growth factor (PDGF)-AA were found to be significantly higher and vascular endothelial growth factor (VEGF) was detected to be lower in high myopic eyes (all P = .03). Multi-plex bead-based assay further validated the differential expressions of four growth factors and all of them were significantly correlated with axial length (P < .001). Twenty-six proteins were mapped into PPI network and positive regulation of cell migration, cellular component movement, and cell motility were the most enriched biological processes based on GO analysis.Conclusions: Differential expressed cytokines that indicates a distinctive intraocular microenvironment in high myopic eyes might provide clues for pathological changes within high myopic eyes after anti-VEGF injections.

Abstract
PURPOSE To investigate the influence of unilateral ultraviolet radiation (UVR) exposure on the unexposed, partner eye in vivo. To characterize the immunological cross-talk between the eyes and verify a sympathizing reaction of the partner eye via a neurokinin-dependent signaling pathway of substance P and its neurokinin-1 receptor (NKR-1) and/or monocyte chemoattractant protein-1 (MCP-1). METHODS C57BL/6 mice were unilaterally exposed in vivo to UVR-B to a 5-fold cataract threshold equivalent dose of 14.5 kJ/m2 with a UV irradiation Bio-Spectra system. The unexposed contralateral eye was completely shielded during irradiation. After 3 and 7 days post exposure, eyes were stained with fluorescence-coupled antibody for substance P NKR-1. The same was performed in control animals receiving only anesthesia but no UVR-B exposure. NKR-1 and MCP-1 levels in ocular tissue lysates were quantified by enzyme-linked immunosorbent assay. RESULTS UVR-B induces NKR-1 upregulation after 3 and 7 days in the exposed and in the unexposed, contralateral mouse eye. NKR-1 protein level was upregulated in the exposed and contralateral iris/ciliary body complex, choroidea and in the contralateral retina as well as in the exposed cornea. MCP-1 levels were elevated in the exposed cornea, iris/ciliary body complex, and aqueous humor but not in contralateral ocular tissues. CONCLUSIONS UVR-B exposure triggers NKR-1 upregulation not only in the exposed but also in the unexposed, partner eye in various ocular tissues. Following UVR-B exposure, MCP-1 protein levels are upregulated in the exposed eye, but the contralateral side remains unaffected.

Pain Perception of the First Eye versus the Second Eye during Phacoemulsification under Local Anesthesia for Patients Going through Cataract Surgery: A Systematic Review and Meta-Analysis. J Ophthalmol 2019; 2019:4106893. [PMID: 31341651 PMCID: PMC6612398 DOI: 10.1155/2019/4106893] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Accepted: 04/21/2019] [Indexed: 01/11/2023] Open
Abstract
Background Phacoemulsification under local anesthesia is regarded as the major surgery for cataract treatment. Recent research has compared the pain perception between the first eye and the second eye during phacoemulsification. However, these studies have also yielded controversial findings. Consequently, we performed a systematic review and a meta-analysis to investigate the difference in the pain perception between the first and second eyes during phacoemulsification. Method We searched the PubMed, EMBASE, and Cochrane CENTRAL databases for the studies published up to October 5, 2018. Prospective observational studies were included. The meta-analysis was conducted by means of random-effects model and fixed-effects model according to the heterogeneity. Evaluation of the methodological quality of studies was based on Newcastle-Ottawa Scale (NOS). Results Overall, eight studies were included in the meta-analysis. The analysis of pooled data showed that the pain scores of the first eye shortly after surgery under local anesthesia were significantly lower as compared to the second eye (WMD: 0.69; 95% CI: 0.40, 0.98; P < 0.00001). The average pain scores of the first eye shortly after surgery under the topical anesthesia were also lower than those of the second eye (WMD: 1.08; 95% CI: 0.79, 1.36; P < 0.00001). Conversely, anxiety scores in the first eye surgery were significantly higher than those in the second eye surgery (SMD: −0.40; 95% CI: −0.64, −0.16; P=0.001). However, the difference of the pain scores accessed on the first postoperative day between the first and second eye surgeries (WMD: −0.05; 95% CI −0.40, 0.31; P=0.79) as well as cooperation grades of patients between the first and second eye surgeries (WMD: 0.35; 95% CI −0.07, 0.76; P=0.10) was not statistically significant. Conclusion Patients experienced more pain in the surgery of the second eye than that of the first eye, which probably related to lower anxiety before the second surgery. It suggests that we should consider preoperative intervention to reduce the perceived pain during second eye cataract surgery.

Abstract
OBJECTIVE To describe clinical features of dogs with lipemic uveitis (LU). ANIMALS STUDIED Seventy-five dogs (114 eyes) with LU. PROCEDURES Medical records of dogs examined by the Cornell University ophthalmology service with a clinical diagnosis of LU between 2008 and 2017 were analyzed. Signalment and clinical case aspects, including concurrent ocular disease, systemic disease, and previous ophthalmic surgery, were recorded. RESULTS Lipemic uveitis was diagnosed in 114 eyes of 75 dogs. The mean (±standard deviation) age of dogs was 9.0 years (±2.7 years). Miniature Schnauzers and Yorkshire Terriers were statistically overrepresented compared to the ophthalmology canine referral population. Lipemic flare varied in severity with loss of menace response due to markedly opaque flare seen in 15/114 eyes (13%). Two dogs developed LU after dietary indiscretion. Forty-nine eyes (43%) had concurrent ocular disease, most commonly keratoconjunctivitis sicca, ulcerative keratitis, and cataracts. Pseudophakia was present in 75/114 eyes (66%) and LU developed within 30 days of an intraocular surgical procedure in 63/114 eyes (55%). Hypertriglyceridemia was noted in 52 dogs of the 55 dogs tested (95%). Systemic disease affected 54/75 dogs (72%), of which diabetes mellitus, hyperadrenocorticism, and hypothyroidism were overrepresented compared to the referral population. Primary hyperlipidemia was identified in 12 dogs. Lipemic uveitis resolved at first reevaluation in 92/110 eyes (84%) and recurred in 6/114 eyes (5%) after complete resolution. CONCLUSIONS Development of lipemic uveitis in dogs appears to require the combination of hyperlipidemia and uveitis. Systemic disease is commonly associated with LU in dogs.

Abstract
PURPOSE To investigate the serial choroidal volume change following orbital blow-out fracture (BOF) repair. METHODS The choroidal volume was measured by optical coherence tomography in patients who underwent BOF repair, preoperatively and postoperatively at 1, 4, 12 and 24 weeks. The orbital volume ratio (OVR) was obtained by dividing the orbital volume of the traumatized orbit by that of the contralateral side using three-dimensional computed tomography imaging. The choroidal volume change was compared between both eyes using a linear mixed model. RESULTS We analyzed the choroidal volume of 11 patients. Choroidal volume showed a trend of slight increase during the immediate postoperative period, and then, choroidal volume decreased abruptly between postoperative 1 to 4 weeks (β-coefficient - 0.22, P < 0.001). Choroidal volume also showed gradual decrease between postoperative 4 to 24 weeks (β-coefficient - 0.02, P < 0.001). During the study period, there were no significant differences in choroidal volume change between BOF and contralateral unaffected eyes (β-coefficient - 0.20, P = 0.711). The hyperopic refractive errors (β-coefficient 0.27, P = 0.028) and the larger preoperative OVR (β-coefficient 10.37, P = 0.013) were associated with larger choroidal volume. CONCLUSIONS Choroidal volume showed a similar decreasing change following BOF repair between the BOF and the contralateral unaffected eyes. Moreover, choroidal volume of both eyes was associated with the degree of orbital volume expansion due to BOF, suggesting that choroidal volume change after BOF repair was affected not only by trauma-associated local hemodynamic changes but also by systemic influences such as inflammatory response.

Curr Eye Res 2018; 43:1445-1453. [PMID: 30009640 DOI: 10.1080/02713683.2018.1501489] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/28/2022]
Abstract
PURPOSE To compare the efficacy and tolerability of diclofenac and bromfenac ophthalmic solutions as adjunctive therapy after cataract surgery. MATERIALS AND METHODS This prospective randomized controlled study included 130 patients who underwent cataract surgery. One hundred patients were randomized to receive postoperatively diclofenac 0.1% (four times daily for 28 days, Group 1) or bromfenac 0.09% (twice daily for 14 days, Group 2) ophthalmic solutions in addition to steroid-antibiotic combination. Thirty patients instilled only steroid-antibiotic combination (Control Group 3). Laser flare-cell photometry and optical coherence tomography scans with central foveal thickness (CFT) measurement were performed before (V0) and 7 (V1), 14 (V2) and 28 days (V3) after surgery. Treatment tolerability was scored using the Ocular Comfort Grading Assessment. RESULTS Laser flare-cell photometry values were significantly higher at V1, V2 and V3 compared to V0 in all the groups (respectively 13.3 ± 1.0, 12.7 ± 0.9 and 9.6 ± 0.9 vs 8.4 ± 0.6 ph/ms for Group 1; 13.4 ± 1.0, 12.7 ± 0.9 and 12.7 ± 1.0 vs 8.1 ± 0.6 for Group 2; 15.9 ± 0.8, 15.4 ± 0.7 and 14.5 ± 0.7 vs 7.5 ± 0.5 for Group 3) (p < 0.001); flare increase was significantly lower in Group 1 compared to Groups 2 and 3 (p < 0.001). CFT values were higher after surgery in all the three groups; the increase was significantly lower in Group 1 compared to Groups 2 and 3 (p < 0.0002). The percentage of symptoms-free patients after study treatment was significantly higher in Group 2 compared to Group 1 (respectively 74% vs 14% of the total; p < 0.001). CONCLUSION The addition of diclofenac or bromfenac ophthalmic solutions contributed to further reduce both inflammation and cystoid macular edema after cataract surgery compared to steroid-antibiotic combination alone. Diclofenac appeared to be more effective in reducing postoperative intraocular inflammation with a more intense and prolonged regimen, while bromfenac more tolerated with lower daily dose and treatment duration.

Abstract
The aim of our present study is to evaluate the efficacy of pranoprofen eye drops as pain relief during sequential second-eye cataract surgery and to investigate the possible mechanism. Seventy-six patients scheduled for bilateral sequential cataract surgery were randomly assigned to two groups: (1) treatment group (administered pranoprofen eye drops), or (2) control group (administered artificial tears). Preoperative anxiety and intraoperative pain were assessed. Monocyte chemoattractant protein 1 (MCP-1) in the aqueous humor was measured with a suspension cytokine array. An extracapsular lens extraction model was established in the Wistar rat and the MCP-1 concentrations were measured with an enzyme-linked immunosorbent assay. We found that in the control group, the pain scores were significantly higher during second-eye surgery than during first-eye surgery (both scores P < 0.001). In the treatment group, there was no significant difference in the pain scores during first-eye and second-eye surgery (both scores P > 0.1). The pain during second-eye surgery was significantly lower in the treatment group than in the control group (both scores P < 0.01). And in the 1-week and 6-week interval subgroups, the pain scores during second-eye surgery were significantly lower in the treatment group than the control group (P = 0.047 and P = 0.035, respectively). While the second-eye MCP-1 level was significantly lower after a 1-week interval in the treatment group than in the control group (P = 0.012), but did not differ significantly after a 6-week interval (P > 0.1). A parallel trend in the MCP-1 concentration was detected in the rat model. In conclusion, the preoperative administration of pranoprofen eye drops reduced the perceived pain during second-eye cataract surgery, especially when performed after 1-week and 6-week intervals between the first-eye and second-eye surgery. MCP-1, a pain-related cytokine, was associated with the pain-relief mechanism of pranoprofen when second-eye surgery was performed 1 week after second-eye surgery.

Abstract
PURPOSE To evaluate bilateral tear function and corneal sensitivity in patients with unilateral quiescent herpes simplex keratitis (HSK) and determine the correlation between corneal sensitivity and tear secretion in both eyes. METHODS Thirty-five patients diagnosed with unilateral quiescent HSK and 35 heathy controls were included in this study. Bilateral tear osmolarity, Schirmer's test, the tear break-up time (TBUT) and corneal sensitivity were measured in all participants. RESULTS In the HSK group, both eyes demonstrated a significant increase in tear osmolarity, and a decrease in Schirmer's test and the TBUT compared with healthy controls (All p < 0.001). The bilateral tear osmolarity and Schirmer's test were similar, but the TBUT (4.9 ± 2.1 versus 7.4 ± 2.0 second; p < 0.001) and corneal sensitivity (35.1 ± 1.9 versus 54.3 ± 0.8 mm; p < 0.001) were significantly lower in the affected eyes. The bilateral tear osmolarity, Schirmer's test and the TBUT were significantly correlated with corneal sensitivity of the affected eye (All p < 0.001). When corneal sensitivity of the unaffected eye was treated as a control variable, tear osmolarity (R = -0.626, p < 0.001), Schirmer's test (R = 0.739, p < 0.001) and the TBUT (R = 0.691, p < 0.001) of the unaffected eyes were still significantly correlated with the corneal sensitivity of the affected eyes. CONCLUSIONS Unilateral quiescent HSK causes bilateral tear impairment, which depends on the loss of corneal sensitivity in the affected eye. In the affected eye with severe corneal sensitivity loss, bilateral dry eye occurred.

Abstract
OBJECTIVE Herbal extract compositions are largely used to manage vein diseases. We prepared a new composition of herbs, named FLEBO OK™, that, when administered as a nutraceutical to patients affected by peripheral vascular diseases, was able to improve their health conditions. We analyzed the effects of this nutraceutical composition on in vitro cultured cells with the aim to obtain information about its mechanisms of action. METHODS A culture of human osteoblast cell line Saos-2 was stimulated with tumor necrosis factor (TNF)-α or interleukin (IL)-1β to induce the expression of some chemokines and matrix metalloproteases (MMPs). This cell culture was then exposed to the prepared composition and the amount of expression of the genes coding for the monocyte chemotactic protein (MCP)-1, IL-8, IL-1β, MMP-2, MMP-3, MMP-9 proteins was measured by real-time polymerase chain reaction (RT-PCR). The experiments were repeated exposing the cells to the same amount of the well-known micronized purified flavonoid fraction. Moreover, we describe the effects of the administration of nutraceutical composition to 20 patients affected by peripheral vascular diseases and 20 healthy individuals. RESULTS The RT-PCR analyses showed that the new composition induces the expression of MMP-3 and MMP-9 and downregulates MMP-2 in cell cultures stimulated with IL-1β, whereas it induces the expression of IL-8 and represses the expression of IL-1β and MCP-1 in cell cultures stimulated with TNF-α. The induction of the expression of MMP-3 and the downregulation of MCP-1 might result in an antiplatelet activity that was not observed for the micronized purified flavonoid fraction. Interviewed patients reported an improvement in their conditions after 1 month of FLEBO OK treatment. CONCLUSION These findings could provide a hypothesis for the high efficiency of the identified nutraceutical composition to management of peripheral vascular diseases.

Comparing Trabeculectomy Outcomes between First and Second Operated Eyes: A Multicenter Study. PLoS One 2016; 11:e0162569.

Abstract
Objective To compare surgical outcomes between the first and second operated eyes in patients who underwent trabeculectomy in both eyes. Methods This retrospective clinical cohort study at five clinical centers in Japan included 84 patients with open-angle glaucoma who underwent primary trabeculectomy in both eyes. The primary outcome was surgical success or failure, with failure being defined according to three criteria: <20% reduction of the preoperative intraocular pressure (IOP), or Criterion A, IOP >21 mmHg; Criterion B, IOP >18 mmHg; or Criterion C, IOP >15 mmHg. Cases of reoperation, a loss of light perception vision, or hypotony were also considered as “failures”. Results There were no significant differences in success rate for any of the three criteria between the first and second operated eyes. For patients whose first trabeculectomy was successful, when the second trabeculectomy was performed ≥2 months after the first, the survival curves for all three criteria for the second trabeculectomy were significantly worse than those for patients waiting a shorter interval between trabeculectomies (Criterion A, 52.0% vs 83.6%, P = 0.0031; Criterion B, 51.5% vs 80.4%, P = 0.026; Criterion C, 51.1% vs 80.4%, P = 0.048). In multivariable analyses, a longer interval between trabeculectomies was a significant prognostic factor for surgical failure (Criterion A, P = 0.0055; Criterion B, P = 0.0023; Criterion C, P = 0.027). However, no dependency on the interval between trabeculectomies was found among patients whose first trabeculectomy failed. Conclusions If the first trabeculectomy is successful, a long interval before the second trabeculectomy increases the risk of surgical failure in the second eye. This result has clinical implications for developing surgical strategies for patients with bilateral glaucoma.

Comparison between Subjective Sensations during First and Second Phacoemulsification Eye Surgeries in Patients with Bilateral Cataract. J Ophthalmol 2016; 2016:6521567. [PMID: 27239336 PMCID: PMC4863115 DOI: 10.1155/2016/6521567] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2016] [Revised: 04/08/2016] [Accepted: 04/17/2016] [Indexed: 11/17/2022] Open
Abstract
Purpose. To evaluate and compare the subjective sensations reported by patients during first and second cataract extractions. Methods. Consecutive patients undergoing bilateral sequential cataract extraction using phacoemulsification were recruited. Following cataract surgery, patients completed questionnaires designed to evaluate subjective sensations, including anxiety, eye bulges, pain, and light sensitivity. Changes in painful sensations experienced by patients between the two surgeries were also recorded. Comparisons were also performed for each subjective sensation between different age groups (<50, 50-59, 60-69, 70-79, and >79 years). Results. A total of 127 patients were included in the final evaluation. Statistical comparison of the results showed that there were significant differences in perception of anxiety, eye bulges, and pain scores between the first and second cataract surgeries (P < 0.05). However, there was no statistically significant difference for light sensitivity scores between the two surgeries (P = 0.555). The differences in anxiety, perception of eye bulges, pain, and light sensitivity scores between both the surgeries showed no correlation with age (P > 0.05 for all). Conclusions. Our research confirms the common observation that patients with bilateral cataracts often report more ocular discomfort during the second surgery. There are, therefore, additional factors that should be considered upon treating patients with bilateral cataracts, and the provision of preoperative counseling could play an important role in providing adequate patient care.
