ABSTRACT
PURPOSE: The cataract surgery dissatisfaction rate is 20% to 35% due to ocular surface discomfort. We investigate the ocular surface discomfort after surgical failure as a consequence of age-related parainflammation. We also aim to prevent it by immune-modulating prophylactic management. METHODS: Monocentric clinical trial realized in a teaching hospital. Prospective, randomized, open-label, unmasked clinical trial. One hundred patients diagnosed with cataracts underwent phacoemulsification surgery. Groups A (<65 years; n = 25) and B (>75 years; n = 25) received surgery only. Groups C and D (both >75 years and both n = 25) used cyclosporine A 0.1% cationic emulsion (CE) eye drops or CE lubricating eye drops (both twice daily), respectively, for 30 days before surgery. Patients were followed up 90 days after surgery. The primary outcome was postoperative ocular surface failure; secondary outcomes examined the influence of prophylactic cyclosporine A 0.1% CE therapy on ocular surface outcomes. RESULTS: Group B demonstrated greater severity regarding ocular surface signs and symptoms throughout the study period, versus all other groups. Signs/symptoms were typically lower in Group A. Group C achieved significant reductions in conjunctival Symptom Assessment in Dry Eye values ( P < 0.05), conjunctival hyperemia severity ( P < 0.01), and meibomian gland dysfunction ( P < 0.001) at Day 45, versus Group B, and tear break-up time was increased ( P < 0.001). Ocular surface inflammatory marker transcription (HLADR, intercellular adhesion molecule 1 [ICAM-1], and interleukin 6 [IL-6]) was significantly downregulated in Group C, versus Group B, at 90 days ( P < 0.05). CONCLUSIONS: Cataract surgery induced ocular surface system failure with a clinically significant persistent inflammatory status (InflammAging) in patients older than 75 years. Prophylactic cyclosporine A 0.1% CE eye drops were associated with improved ocular surface homeostasis and reductions in inflammatory markers.
ABSTRACT
PURPOSE: To investigate the influence of vitreous cortex remnants (VCRs) removal on normal retinal anatomy in eyes with rhegmatogenous retinal detachment (RRD). DESIGN: Prospective cohort study. SUBJECTS: Patients with primary RRD operated with pars plana vitrectomy (PPV). METHODS: Blue fundus autofluorescence and spectral-domain OCT were obtained preoperatively, and at 1 and 6 months after operation. MAIN OUTCOME MEASURES: Primary outcomes: rate of retinal displacement and outer retinal folds (ORFs) at 1 month after operation. SECONDARY OUTCOMES: continuity of the external limiting membrane (ELM) and ellipsoid zone (EZ), and the logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) at 6 months after operation. RESULTS: One hundred three eyes were included. Intraoperatively, peripheral VCRs (pVCRs) were found in 42 eyes (40.8%) and successfully peeled off from ≥2 quadrants in 37 eyes. Macular VCRs (mVCRs) were detected in 37 (35.9%) and successfully peeled off in 29 eyes. At the end of operation 44.7% and 55.3% of the eyes were tamponaded with 20% sulfur hexafluoride gas and silicone oil 1000 centistokes, respectively. The only variable significantly associated with displacement was the use of gas tamponade versus silicone oil (P = 0.001), whereas no significant association was found between retinal displacement and pVCRs (P = 0.58) or number of quadrants from which pVCRs were peeled off (P = 0.39). At 1 month postoperatively, ORFs were globally detected in 24 eyes (23.3%). Regression analysis showed a direct correlation between ORFs and the intraoperative detection of mVCRs (P = 0.02) and an indirect correlation between ORFs and mVCRs peeling (P = 0.004). Macular VCRs peeling did not influence the continuity of ELM and EZ at the 6-month follow-up (FU). Intraoperative absence of mVCRs (P = 0.0016) and peeling of mVCRs (P = 0.003) were associated with logMAR BCVA ≤0.3 at the 6-month FU. CONCLUSIONS: Peeling of pVCRs did not seem to influence the rate of retinal displacement, whereas peeling of mVCRs was associated with a reduced risk of developing ORFs without detrimental effect on the continuity of ELM/EZ at 6-month FU. The patients without mVCRs detected intraoperatively, or who underwent mVCRs peeling during operation, showed a significantly better visual acuity at the 6-month FU.

ABSTRACT
Purpose: To evaluate the anatomical and functional outcomes of intravitreal brolucizumab in eyes with chronic central serous chorioretinopathy complicated by pachychoroid neovasculopathy. Methods: Retrospective analysis of 34 eyes treated with intravitreal brolucizumab. Twenty-five eyes (73.5%) had been treated with other anti-vascular endothelial growth factor agents before switching to brolucizumab, whereas nine eyes were naïve. Outcome measures included the change of central foveal thickness and subfoveal choroidal thickness, evaluation of sub/intraretinal fluid on optical coherence tomography, and change in best-corrected visual acuity. Results: Before starting brolucizumab, 23 eyes showed subretinal fluid, 8 both subretinal and intraretinal fluid, and 3 intraretinal fluid only. At the last visit, 22 eyes (64.7%) showed complete reabsorption of both intraretinal and subretinal fluid, whereas subretinal fluid was still present in 8 eyes (23.5%), and both intraretinal and subretinal fluid in 4 eyes (11.8%). The mean number of brolucizumab injections required to achieve complete fluid reabsorption was 2.8 ± 1.8. central foveal thickness decreased from 317.8 ± 109.3 µm to 239.8 ± 74.8 µm (P = 0.0005) and subfoveal choroidal thickness decreased from 399.3 ± 86.2 µm to 355.5 ± 92.7 µm at the end of the follow-up period (P = 0.0008). The mean logarithm of the minimum angle of resolution best-corrected visual acuity improved from 0.4 ± 0.2 to 0.3 ± 0.2 at 1 month after the first injection and remained stable at the same values at the end of the follow-up period (P = 0.04). Conclusions: Intravitreal brolucizumab is effective for the treatment of naïve and recalcitrant pachychoroid neovasculopathy. Translational Relevance: Intravitreal brolucizumab may represent an option in patients with pachychoroid neovasculopathy complicating chronic central serous chorioretinopathy.

Purpose: The purpose of this study was to identify pre-operative biomarkers of vitreous cortex remnants (VCRs) in eyes with rhegmatogenous retinal detachment (RRD). Methods: Prospective case series of 103 eyes treated with pars plana vitrectomy (PPV) to repair RRD. Pre-operatively, optical coherence tomography (OCT) and B-scan ultrasonography (US) were used to study the vitreo-retinal interface and vitreous cortex status. If detected during PPV, VCRs were removed. Images acquired pre-operatively were compared with intra-operative findings and with postoperative OCT images taken at 1, 3, and 6 months of follow-up. Multivariate regression analyses were performed to determine associations between VCRs and pre-operative variables. Results: The presence of VCRs at the macula (mVCRs) and at the periphery (pVCRs), was ascertained intra-operatively in 57.3% and 53.4% of the eyes, respectively. Pre-operatively, a preretinal hyper-reflective layer (PHL) and a saw-toothed aspect of the retinal surface (SRS) were identified with OCT in 73.8% and 66% of the eyes, respectively. US sections showed a vitreous cortex running close and parallel to the detached retina upon static and kinetic examination (the "lining sign") in 52.4% of the cases. Multivariate regression analyses showed an association between PHL and SRS and intra-operative evidence of mVCRs (P = 0.003 and < 0.0001, respectively) and between SRS and "lining sign" and pVCRs (P = 0.0006 and 0.04, respectively). Conclusions: PHL and SRS on OCT and the "lining sign" on US appear to be useful pre-operative biomarkers of the intra-operative presence of VCRs. Translational Relevance: Preoperative identification of VCRs biomarkers may help to plan the operating strategy in eyes with RRD.
