Purpose: To investigate the role of some blood count–derived inflammation biomarkers in age-related macular degeneration (AMD). Methods: Seventy-nine men with late-stage AMD and 79 male age-matched cataract controls without AMD were recruited in March–December, 2016. A blood sample was taken. The following blood cell count–derived indexes were evaluated: neutrophil/lymphocyte ratio (NLR), derived NLR [dNLR = neutrophils/(white blood cells ‒ neutrophils)], platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), (neutrophils × monocytes)/lymphocyte ratio (SIRI), and (neutrophils × monocytes × platelets)/lymphocyte ratio (AISI). Results: AMD patients had significantly lower median values of white blood cells, monocytes, neutrophils, platelets, and mean platelet volume (MPV). Regarding the combined indexes, only AISI was significantly lower in AMD patients than in controls. Receiver operating characteristics curve analysis revealed that the ability of AISI and MPV to predict AMD is poor. Conclusion: Results suggests that NLR, dNLR, PLR, MLR, SIRI, and AISI are unreliable disease biomarkers in men with AMD. Larger scale studies are necessary to confirm these findings.

Purpose: To evaluate the efficacy and safety of topical bromfenac in patients with newly diagnosed diabetic macular edema (DME). Methods: In this pilot study including 17 patients with monocular, newly diagnosed DME, diagnosis of DME was established by the detection of retinal thickening at or within 500 μm of the center of the macula on ophthalmoscopic examination, according to the Early Treatment Diabetic Retinopathy Study classification. Central macular thickness (CMT) was determined by optical coherence tomography. Bromfenac sodium hydrate 0.9 mg/mL eyedrops were administered in the affected eye twice daily for 30 days. Primary endpoints were changes in best-corrected visual acuity (BCVA) and CMT at the end of therapy. Results: Topical bromfenac significantly reduced mean CMT, from 465.41 ± 118.47 μm at baseline to 388.88 ± 152.63 μm posttreatment (p = 0.02). There was no significant change in BCVA and differences in mean macular volume fell just short of statistical significance (p = 0.06). Treatment was well-tolerated, and there were no topical or systemic side effects. Conclusions: Topical bromfenac twice daily may play a role in the reduction of DME. These preliminary results warrant further larger multicenter studies to confirm our findings and establish whether topical bromfenac may be of long-term benefit in the treatment of DME.

Purpose. To investigate the effectiveness and safety of combined phacoemulsification and dexamethasone intravitreal implant in patients with cataract and diabetic macular edema. Methods. In this two-center, retrospective, single-group study, the charts of 16 consecutive patients who underwent combined phacoemulsification and intravitreal dexamethasone implant were retrospectively reviewed. These 16 patients, 7 men and 9 women, were observed at least 3 months of follow-up. Primary outcome was the change of the central retinal thickness (CRT); secondary outcome was the change of best-corrected visual acuity (BCVA). Any ocular complications were recorded. Results. Mean CRT decreased significantly from 486 ± 152.4 μm at baseline to 365.5 ± 91 μm at 30 days (p=.005), to 326 ± 80 μm at 60 days (p=.0004), and to 362 ± 134 μm at 90 days (p=.001). Mean BCVA was 20/105 (logMAR, 0.72 ± 0.34) at baseline and improved significantly (p≤.007) at all postsurgery time points. One case of ocular hypertension was observed and successfully managed with topical therapy. No endophthalmitis or other ocular complications were observed. Conclusion. Intravitreal slow-release dexamethasone implant combined with cataract surgery may be an effective approach on morphologic and functional outcomes for patients with cataract and diabetic macular edema for at least three months after surgery.
