Abstract
PURPOSE Periodontitis causes low-grade systemic inflammation and has been associated with elevated active-matrix metalloproteinase (aMMP-8) levels, blood-ocular barrier breakdown and a risk of wet age-related macular degeneration. To assess the association between aMMP-8 levels and macular status among patients with wet age-related macular degeneration (AMD). METHODS Patients on anti-VEGF treatment for wet AMD were enrolled for oral aMMP-8 rinse test in Mehiläinen Private Hospital, Helsinki, Finland. Macular status was examined from spectral-domain optical coherence tomography (SD-OCT) scans by a medical retina specialist and aMMP-8 levels were analyzed with chairside point-of-care oral rinse (PerioSafe®) test and real-time quantitated by a dentist using the ORALyzer®- reader with a 10 ng/ml cut-off for aMMP-8 activity. RESULTS Elevated aMMP-8 levels were found in 10 out of 32 patients. Age, gender, anti-VEGF (bevacizumab or aflibercept) distribution, cumulative number of anti-VEGF injections and treatment interval were comparable between patients with aMMP-8 levels below and above the point-of-care level. Macular status differed in regard to aMMP-8 activity; among patients with aMMP-8 levels below the point-of-care subretinal fibrosis was found in 6 out of 22 eyes, whereas among patients with aMMP-8 levels above the point-of-care subretinal fibrosis was found in 8 out of 10 eyes (p = 0.005). Respectively, the mean thickness of subretinal fibrosis at fovea was 19.5 ± 44.1 and 92.3 ± 78.3 µm (p = 0.018). No differences were found in the presence and in the area of geographic atrophy, or fluid distribution, whereas thicknesses of serous pigment epithelial detachment (65.5 ± 99.5 and 12.9 ± 27.9 µm, p = 0.038) and neuroretina (204.2 ± 57.8 µm and 143.0 ± 43.7 µm, p = 0.006) were greater in the eyes of patients with physiological aMMP-8 levels compared to those with elevated aMMP-8 levels. CONCLUSION Elevated aMMP-8 levels may account for subretinal fibrosis formation in wet AMD.

Baseline characteristics associated with the incidence of intraocular inflammation after the intravitreous injection of brolucizumab. Int Ophthalmol 2023; 43:4701-4709. [PMID: 38044420 DOI: 10.1007/s10792-023-02870-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 08/20/2023] [Indexed: 12/05/2023]
Abstract
PURPOSE To investigate baseline characteristics associated with the incidence of intraocular inflammation (IOI) after the intravitreal injection of brolucizumab (IVBr) for the treatment of neovascular age-related macular degeneration (nAMD). METHODS This retrospective study included 66 eyes of 62 consecutive patients with nAMD who received IVBr (18 eyes were treatment naïve and 48 eyes had switched from other anti-vascular endothelial growth factor [VEGF] therapy). Baseline clinical characteristics were compared in non-IOI and IOI groups. RESULTS Although a dry macula was achieved at a high rate even 6 months after IVBr, IOI occurred in 8 of 66 eyes (12.1%; all had switched therapy) during the study period. Baseline characteristics including age, sex, nAMD type, lens status, visual acuity, central macular thickness, and a history of diabetes did not differ between the groups. The number of previous anti-VEGF injections before IVBr was greater in the IOI group (P = 0.004), and the ratio of patients with a laser flare-cell photometry (LFCP) value over 15 photon count per millisecond (pc/ms) was higher in the IOI group (P = 0.017). Multivariate logistic regression analysis showed that a greater number of previous anti-VEGF injections (odds ratio [OR]: 1.12, P = 0.006; area under the curve: 0.82, cut-off score: 14.0) and an LFCP value over 15 pc/ms (OR: 81.6, P = 0.031) were significantly associated with the incidence of IOI after IVBr. CONCLUSION A number of previous anti-VEGF injections greater than 14 and an LFCP value more than 15 pc/ms might be useful predictors of the incidence of IOI after IVBr in eyes with nAMD.

Abstract
Purpose Periodontitis causes low-grade systemic inflammation e.g., through circulatory periodontal endotoxins, and it has been associated with cardiovascular morbidity and wet age-related macular degeneration. Methods To assess the association between clinical severity of periodontitis and aqueous flare levels in the eyes. Patients with periodontitis (N = 15) who underwent periodontal treatment by a specialized dentist between the years 2020 and 2021 at the Chin and Mouth Disease Unit, Kymenlaakso Central Hospital, Kotka, Finland were enrolled. Aqueous flare levels, a surrogate marker for blood-aqueous and blood-retinal-barrier disruption, were measured using Laser Flare Meter (FM-600, Kowa Company, Ltd., Nagoya, Japan) before and right after the periodontal treatment and at 3 months. The number of teeth, periodontal probing depth (PPD), periodontal pathogens and antimicrobial treatment were recorded. Results At baseline, aqueous flare levels correlated with the number of clinically-relevant PPD (>5 mm) pockets (R = 0.789, P < 0.001) and inversely correlated with the number of teeth (R = −0.587, P = 0.035). At baseline, aqueous flare levels were 15.39 ± 13.24 photon units (pu)/ms among patients with periodontal pathogens, compared with 3.29 ± 1.67 pu/ms among those without any peridontal pathogens in PCR ( P = 0.018). At 3 months compared to baseline values, aqueous flare levels were reduced to <50% from baseline among 6 patients (40%), whereas the levels increased to >200% from baseline in 1 patient (7%) (repeated measures ANOVA, P < 0.026). Conclusions Poor periodontal status was associated with blood-ocular-barrier breakdown. These findings could expand our understanding of the potential mechanisms and therapeutic targets against retinal vascular diseases and systemic comorbidities in patients with periodontitis.

Abstract
Purpose To assess whether aqueous flare is related to an increased risk of pseudophakic cystoid macular edema (PCME) following uneventful cataract surgery in nondiabetic and diabetic patients. Methods A post hoc analysis of five consecutive randomized clinical trials in the Department of Ophthalmology, Kymenlaakso Central Hospital, Finland. Aqueous flare levels were recorded in 448 eyes of 448 patients before surgery, and after the course of topical anti-inflammatory treatment 28 days and three months after cataract surgery. Results Aqueous flare increase of <50%, ≥50%, ≥100%, and ≥200% associated in central subfield macular thickness (CSMT) increase across the groups at 28 days and three months after surgery. Increase of aqueous flare ≥100% compared to those with <100% was associated with increased CSMT (P = 0.022 at 28 days, and P = 0.027 at three months). At three months, macular thickening (at least 10% CSMT increase) was observed in 12.7% compared to 4.6% of eyes when using a cutoff value of 100% increase in aqueous flare (P = 0.033). Although diabetic patients presented higher aqueous flare levels at baseline compared to nondiabetic patients (12.9 ± 11.8 vs. 9.8 ± 8.2 photon units/ms P < 0.001), the postoperative levels illustrated a similar profile in aqueous flare increase between the two groups. Conclusions At 28 days, aqueous flare increase was associated with macular thickening. A 100% cutoff value could potentially be used when studying anti-inflammatory efficacy of different treatment protocols. Flare values exceeding this cutoff value could be considered as an indication for extending anti-inflammatory therapy. Translational Relevance A 100% increase in aqueous flare at 28 days after cataract surgery from baseline predicted macular thickening up to three months postoperatively. Identifying a correlation between increased aqueous flare levels and pseudophakic cystoid macular edema may allow recognition of the most vulnerable patients, development of prophylactic treatment strategies and reduction of the number and severity of postoperative complications.

Abstract
PURPOSE Novel pupil expansion devices are widely recognized for their intraoperative feasibility in safe small pupil cataract surgeries. To assess whether the use of pupil expansion devices affects recovery from cataract surgery. METHODS A post hoc analysis of five consecutive prospective randomized clinical trials. 536 eyes of 536 patients undergoing routine cataract surgery were analysed according to the use of pupil expansion device. Thirty-four eyes were operated with pupil expansion device and 502 eyes without. Clinical outcome parameters were recorded at 28 days and 3 months. RESULTS Patient age and gender distribution, and baseline clinical outcome parameters were comparable between study groups. Pseudoexfoliation syndrome, glaucoma and medication for benign prostatic hyperplasia were more frequently present; phacoemulsification energy was higher and operation time longer in eyes with pupil expansion device. At 28 days, aqueous flare increased by 12.0 ± 25.1 pu/mseconds and mean central subfield macular thickness by 16.2 ± 24.4 μm in eyes with pupil expansion device, when compared to 4.6 ± 14.8 pu/mseconds (p = 0.015) and 7.0 ± 33.9 μm (p = 0.064) in eyes without the device. At 3-month follow-up, clinically significant pseudophakic cystoid macular edema (PCME) was reported in 12% of eyes with pupil expansion device and in 2% of eyes without (p = 0.006). After adjusting for the presence of confounding factors, hazard for clinically significant PCME was greater in eyes with pupil expansion device than in those without (HR 5.41, 95% CI 1.35-21.71, p = 0.017). CONCLUSIONS The use of pupil expansion device may predispose eyes to increased risk of clinically significant PCME. Effective anti-inflammatory treatment and follow-up are warranted in eyes with pupil expansion device.
