Aim Comparing outcomes after combined phacoemulsification, two iStents insertion and endocyclophotocoagulation (ECP) versus phacoemulsification-iStents alone. Methods This is a longitudinal retrospective 12 months study in eyes with ocular hypertension or early-to-moderate open angle glaucoma. Level of disease, intraocular pressure (IOP) and tolerance of glaucoma medication were considered before planning surgery. Best-corrected visual acuity (BCVA-logMAR), IOP (mm Hg), number of medications were assessed at baseline, week 1, week 5, month 3, 6, 12 postop. Main outcome: percentage (%) in IOP reduction at 12 months vs medicated baseline. Secondary outcomes: absolute values of IOP/medication reduction, BCVA and postop complications. Results The ICE2 (two iStents-cataract extraction-ECP) group included 63 eyes and Phaco-iStent group included 46 eyes. Baseline IOP was higher in the ICE2 than phaco-iStent group (19.97±4.31 mm Hg vs 17.63±3.86 mm Hg, p=0.004) and mean deviation was lower (−7.20±2.58 dB vs −4.94±4.51 dB, p=0.037). Number of medications were comparable at baseline: 2.22±1.06 (ICE2) vs 2.07±1.02 (phaco-iStent), p=0.442. At month 12 postop, IOP in the ICE2 group decreased 35% from baseline vs 21% in the phaco-iStent group (p=0.03); absolute IOP reduction was significantly lower than baseline in each group (p<0.001), yet final IOP was lower in the ICE2 group than phaco-iStent group (13.05±2.18 mm Hg vs 14.09±1.86 mm Hg, p=0.01). Similar results were found for glaucoma medication (1.24±1.05 in ICE2 group vs 1.39±1.03 in phaco-iStent group, p=0.01). Final BCVA was 0.11±0.18 (phaco-iStent group) vs 0.08±0.08 (ICE2 group), p=0.309. Safety outcomes were comparable between groups. Conclusion ICE2 procedure offers better results in IOP/medication reduction at 12 months than phacoemulsification-iStents alone.

Aim: The study assesed trabeculectomy survival in advanced open angle glaucoma (OAG). Methods: This is a retrospective longitudinal study in advanced OAG undergoing primary trabeculectomy. Clinical and demographic parameters were recorded. Surgical survival (qualified/complete) was calculated by Kaplan–Meier analysis for multiple upper limits of intraocular pressure (IOP) with/without medication (≤ 21 mmHg, ≤ 18 mmHg, ≤ 15 mmHg, ≤ 12 mmHg); Cox hazard ratio analysis identified parameters influencing survival. Results: We included 165 eyes from 165 OAG patients: primary forms (POAG) – 86 eyes and secondary (pseudoexfoliative, SOAG) – 79 eyes; mean follow-up interval was 36.21 ± 13.49 months. Clinical parameters were comparable between sub-groups at baseline, except a higher IOP in SOAG vs POAG (36.6 ± 13.2 vs 32.7 ± 11.1 mmHg, p = 0.04); IOP reduction was similar (SOAG vs POAG) 53.93% vs 56.19%, p = 0.45, yet longer hospitalization (8.47 ± 4.39 (SOAG) vs 6.69 ± 3.01 days (POAG), p=0.03) and more medications (0.65 ± 0.24 vs 0.36 ± 0.16, p = 0.05) were needed to achieve comparable final IOP (16.0 ± 9.1 vs 15.1 ± 7.8 mmHg, p = 0.45). Kaplan Meier survival analysis applied for IOP ≤ 21 mmHg, ≤ 18 mmHg, ≤ 15 mmHg and ≤ 12 mmHg, revealed complete success in 26.2%, 27.3%, 34.5% and 54.6% eyes, respectively; qualified success was found in 45.7%, 48.6%, 77% and 88.6% eyes, respectively. Multiple medications at baseline diminished survival in all tested models (hazard ratio HR > 1, p< 0.05), while 5FU+needling improved survival, mostly if combined with lower IOP regime: HR = 0.15, 95% CI = [0.07 − 1.12], p = 0.06, if IOP ≤ 15 mmHg and HR = 0.09, 95% CI = [0.02– 1.25], p = 0.06, if IOP ≤ 12 mmHg. Conclusion: Trabeculectomy in advanced OAG reached very good survival rates (77% and 88.6%) at 36 months postoperative, if IOP could be maintained ≤ 15 mmHg, respectively ≤ 12 mmHg with medication and additional needling+5FU maneuvers. Specific factors influencing survival were identified for each success definition.

Background and Objectives: Cytokines are cell-signaling proteins whose identification may serve as inflammatory markers or early indicators for progressive disease. The aim of our study was to quantify several cytokines in aqueous humor (AH) and their correlations with biochemical parameters in diabetic eyes with non-proliferative diabetic retinopathy (NPDR). Materials and Methods: A total of 62 eyes from 62 patients were included in the study: 37 eyes from nondiabetic patients (group 1), 13 diabetic eyes with no retinopathy changes (group 2) and 12 diabetic eyes with early and moderate NPDR (group 3). AH samples were collected during uneventful cataract surgery. The cytokines IL-1β, IL-6, IL-8, IL-10, IL-12, IP-10, MCP-1, TNF-α and VEGF were quantified using multiplex bead-based immunoassay. Due to unreliable results, IL-1β, TNF-α, IL-10 and IL-12 were excluded. Concentrations were compared between groups. Biochemical parameters (fasting blood sugar, glycated hemoglobin, C-reactive protein) and the duration of diabetes were recorded. Results: VEGF levels were significantly different between groups (p = 0.001), while levels of IL-6, IL-8, IP-10 and MCP-1 were comparable across all groups (p > 0.05). IL-6 concentration correlated with VEGF in group 1 (rho = 0.651, p = 0.003) and group 3 (rho = 0.857, p = 0.007); no correlation could be proved between IL-6, IL-8, IP-10, MCP-1 or VEGF and biochemical parameters. Duration of diabetes was not correlated with the cytokine levels in groups 2 and 3. The receiver operating characteristic (ROC) curve revealed that VEGF concentrations could discriminate early and moderate NPDR from diabetes, with an area under the curve (AUC) of 0.897 (p = 0.001, 95% CI = 0.74–1.0). Conclusions: Diabetes mellitus induces significant intraocular changes in the VEGF expression in diabetic patients vs. normal subjects, even before proliferative complications appear. VEGF was increasingly expressed once the diabetes progressed from no retinopathy to early or moderate retinopathy.

Juvenile xanthogranuloma (JXG) is a benign histiocytic skin disorder mainly encountered during infancy and childhood. Although with multiple potential localizations, less than 1% of the cases exhibit ocular manifestations. Some of these might lead to serious complications, specifically, secondary glaucoma that can result in severe and blinding eye disease. The aim of the present case report was to demonstrate typical clinical features, emphasize the difficulties attributed when managing these patients and literature review. We present the case of 4 months old female baby with spontaneous hyphema and secondary unilateral glaucoma due to ocular JXG. The natural history and treatment of the condition were extremely difficult to handle due to multiple opinions in histopathology related to other severe conditions that resembled with the lesions detected in this case: myelomonocytic leukemia and Langerhans cell histiocytosis. Although a minority of patients with JXG have ocular involvement, recognition of this condition is important because a treatment delay can lead to serious complications, such as glaucoma and spontaneous hyphema, as in our case. A thorough differential diagnosis represents the key to a proper management plan in these patients, both on short and long term. "Triple disease" defined as JXG plus neurofibromatosis type 1 (NF-1) and juvenile chronic myelogenous leukemia (JCML) has been reported, but it was not confirmed in our patient.

AIM: To assess the inflammatory cytokines expression in aqueous humor in diabetic primary open angle glaucoma (POAG) patients. METHODS: A cross-sectional study on 87 eyes, distributed as following: 26 eyes from diabetic patients, 16 eyes with POAG and 21 eyes from diabetic POAG patients; healthy controls (24 eyes) were recruited from patients undergoing conventional cataract surgery. A volume of 100 mu L of aqueous humor (AH) was collected during phacoemulsification and 21 inflammatory markers were quantified using a Luminex (R) cytometric bead assay: IL-1Ra, IL-1 alpha, IL-1 beta, IL-5, IL-6, IL-10, IL-17, GM-CSF, IFNy, CCL2, CCL3, CCL4, CXCL5, CXCL8, bFGF, VEGF, TNF alpha. Main changes in cytokine profile were analyzed and compared between groups. Data on demographics, duration of glaucoma, intraocular pressure (IOP), number of anti-glaucoma substances were recorded for correlation analysis and prediction models. RESULTS: Significant differences in cytokine expression between groups were detected for CXCL5 (P<0.001), CXCL8 (P=0.004), IL-1 alpha (P<0.001), IL-2 (P<0.001), CCL4 (P=0.003), CCL5 (P<0.001) and TNF alpha (P=0.05). Post-hoc analysis identified IL-2 (P=1009) and CXCL5 (P<0.001) as "separation markers" between POAG and diabetic POAG eyes. In POAG patients, the "separation markers" could highly predict the TNF alpha levels F(1, 16)=14.639, P<0.001, whereas in diabetic patients F(1, 24)=4.844, P=0.006 and diabetic POAG patients F(1, 19)=2.358, F=0.05 the level of prediction was inferior. CONCLUSION: Our results reveal an inflammatory model based on increased TNF alpha levels in POAG eyes. Simultaneous co-stimulatory molecules and additional inflammatory pathways need to be further explored in diabetic POAG cases, since the prediction model could only partially explain the increased TNF alpha level in this category of patients.

Purpose: To employ ultrahigh‐resolution (UHR) optical coherence tomography (OCT) for investigation of the early wound healing process in corneal epithelium.Methods: A custom‐built UHR‐OCT system assessed epithelial healing in human keratoconic cornea after epi‐off crosslinking (CXL) procedure and a wound healing model in rabbits with iatrogenic corneal injury. 3D OCT data sets enhanced obtaining epithelial thickness maps and evaluation of reepithelization stage. Accompanying changes in deeper corneal microarchitecture were analysed.Results: The mean central corneal thickness in 40 eyes with keratoconus at baseline was 482.7 ± 38.2 μm, while mean central epithelial thickness (CET) was 43.8 ± 6.4 μm. At the final visit 20 ± 5 days post‐CXL procedure, CET was 35.0 ± 5.8 μm, significantly thinner after reepithelization (p < 0.001). Surgical success was assessed at the final visit through the demarcation line (DL), identified at 43.7 ± 13.5% stromal depth. In rabbits, the mean CET in 20 eyes at baseline was 35.9 ± 2.6 μm. In rabbits that revealed complete wound closure (10/20 eyes) at the last study day at 72 hr, CET was significantly thinner compared to baseline (30.4 ± 2.8 μm versus 35.4 ± 2.9 μm, p = 0.005). An intra‐stromal landmark indicating early keratocyte apoptosis was measured at 30.0 ± 5.1% stromal depth. Epithelial thickness maps showed the time–course of corneal healing.Conclusion: Ultrahigh‐resolution (UHR)‐OCT provided precise assessment of epithelial wound and its healing by 3D‐mapping. In addition, microarchitectural changes in the cornea in early phases of epithelial healing were revealed.
