RESUMO

PURPOSE: To evaluate and compare the long-term outcomes of canaloplasty and phaco-canaloplasty in the treatment of open angle glaucoma and assess the prognostic factors associated with surgical outcome. METHODS: A 48-month retrospective analysis was performed on n = 133 open angle glaucoma eyes treated with canaloplasty and n = 57 open angle glaucoma eyes treated with phaco-canaloplasty by a single surgeon. Surgical success was defined according to six criteria, achieving a target intraocular pressure (IOP) ≤ 21, 18 or 15 mmHg on glaucoma medications (qualified success) or without any further treatment (complete success), including laser therapy or surgery. Kaplan-Meier survival analysis and Cox regression analysis were performed to evaluate surgical success and preoperative factors associated with surgical outcome. Surgical complications in the early postoperative period were compared between canaloplasty and phaco-canaloplasty. RESULTS: Canaloplasty and phaco-canaloplasty significantly reduced postoperative IOP and number of glaucoma medications (p = 0.001 for both). Phaco-canaloplasty showed higher rates of cumulative surgical success over canaloplasty, but only for target IOP ≤ 21 and ≤ 18 (p = 0.018 and p = 0.011, respectively). A preoperative number of > 4 glaucoma medications predicted surgical failure. Phaco-canaloplasty was associated with a higher rate of IOP peaks in the first month compared with canaloplasty (40.4% vs 12.7%, p = 0.000). CONCLUSION: Canaloplasty and phaco-canaloplasty demonstrated long-term efficacy in the treatment of open angle glaucoma, with phaco-canaloplasty showing higher rates of surgical success compared to canaloplasty, but not for target IOPs lower than 16 mmHg. Patients on more than 4 preoperative glaucoma medications may not be good candidates for canaloplasty and may benefit from other surgical options.

RESUMO

PURPOSE: To evaluate and compare the visual outcomes of an enhanced monofocal intraocular lens (IOL) with two different monofocal IOLs. SETTING: Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy. DESIGN: Prospective, single-center, single-masked, randomized controlled clinical study. METHODS: The study included patients undergoing phacoemulsification and IOL implantation. Patients were consecutively randomized by block randomization and assigned in a 1:1:1 allocation ratio to three study arms to bilaterally receive Tecnis Eyhance™ (model ICB00) or Tecnis® monofocal 1-piece (model PCB00) or Clareon® monofocal (model CNA0T0), respectively. Monocular and binocular (both corrected and uncorrected) visual acuities for far, intermediate and near were registered and compared among groups at 3 months. To track changes in patient quality of life, the Catquest-9SF questionnaire was administered to each patient before and after cataract extraction. RESULTS: Ninety patients (30 for each group) were enrolled. At 3 months follow-up, statistically significant differences for intermediate visual acuities were found between the three groups. Nonstatistically significant differences were observed for distance visual acuities and the changes in Catquest-9SF scores. CONCLUSION: Tecnis Eyhance™ provided better results in intermediate visual outcomes without adverse effects on patients' quality of life.

RESUMO

PURPOSE: To evaluate and compare the long-term results after bilateral implantation of different multifocal intraocular lenses (MIOLs). METHODS: This retrospective comparative study included 42 patients who underwent cataract surgery with bilateral MIOL implantation. Patients were divided into 5 groups: Group 1 received a refractive ReZoom NGX1 IOL (AMO), Group 2 a diffractive Acrysof ReSTOR SA60D3 IOL (Alcon), and Group 3 a diffractive Tecnis ZM900 IOL (AMO). Group 4 and Group 5 were implanted using the mix and match approach with refractive ReZoom-diffractive ReSTOR IOL and refractive ReZoom-diffractive Tecnis ZM900 IOL, respectively. Primary outcome measures were distance, near, and intermediate distance visual acuity measured 6 months (T0) and 10 years (T1) after surgery. Secondary outcomes were defocus curves, contrast sensitivity, patients' satisfaction, and spectacle independence. RESULTS: All patients achieved best-corrected distance visual acuity (BCDVA) greater than 0.11 logMAR and uncorrected distance visual acuity (UCDVA) greater than 0.14 logMAR at both time points. A decrease in contrast sensitivity was evident, particularly at high spatial frequencies; at T1, Group 4 reported statistically higher values than Group 2 at 12 cycles/degree and 18 cycles/degree and statistically higher values than Group 3 at 18 cycles/degree. Great overall satisfaction was reported even in the presence of dysphotopsia. Tecnis ZM900 IOL showed the lowest incidence of posterior capsular opacification. CONCLUSION: MIOLs could provide adequate functional vision and patient satisfaction, despite the incidence of side effects, in carefully selected patients desiring spectacle independence.

RESUMO

BACKGROUND: It is known that cataract extraction is associated with a significant reduction in intraocular pressure, especially in narrow angled eyes; however, the modifications of anterior segment parameters associated with this phenomenon have still not been completely defined. The purpose of this study was to evaluate changes in anterior segment anatomy and intraocular pressure after cataract surgery in non-glaucomatous eyes. METHODS AND MATERIAL: This retrospective case series study included 64 eyes of 64 consecutive patients who underwent phacoemulsification with intraocular lens implantation. Anterior segment parameters and intraocular pressure were assessed and compared before and 6 months after surgery. Anterior segment imaging was performed using Casia SS-1000 anterior segment optical coherence tomography (Tomey, Nagoya, Japan). Anterior segment measurements included anterior chamber depth, anterior chamber width, anterior chamber volume, angle opening distance at 500 µm anterior to the scleral spur, angle recess area 750 µm from the scleral spur, lens vault, trabecular iris space area at 500 µm from the scleral spur, and trabecular iris angle at 500 µm from the scleral spur. Intraocular pressure was measured using the Goldmann applanation tonometer (Model AT 900 C/M, Haag-Streit, Bern, Switzerland). Anterior segment parameters and the relationship of changes in intraocular pressure were also evaluated. RESULTS: All anterior segment parameters increased significantly after surgery (p < 0.05). Both angle opening distance at 500 µm anterior to the scleral spur and anterior chamber depth changes were positively correlated with the preoperative lens vault. The mean intraocular pressure significantly decreased from 14.91 mmHg (± 2.8 SD) to 12.91 mmHg (± 3.13 SD) (p < 0.001). Changes in intraocular pressure correlated negatively with values for the width of the preoperative anterior chamber (r = - 0.533; p = 0.001). CONCLUSION: Cataract surgery led to significant widening of the anterior chamber angle and lowering of intraocular pressure. Further investigations are needed to better understand whether anterior chamber width may be a new independent predictive factor for reduction in postoperative intraocular pressure.

RESUMO

PURPOSE: In the era of antibiotic resistance, there is an increased interest in antiseptic solutions that might represent a reliable option for ocular surface disinfection. The objective of this study is to compare for the first time three different antiseptic ophthalmic preparations to assess their in vitro antimicrobial activity. METHODS: The antiseptic activity of three commercial ophthalmic solutions, IODIM (povidone-iodine 0.6% in hyaluronic acid vehicle-Medivis, Catania, Italy), OZODROP (nanoemulsion with ozonated oil-concentration not specified-FBVision, Ophthalmic Pharmaceuticals, Rome, Italy), and DROPSEPT (chlorhexidine 0.02% and vitamin E 0.5% Tocopherol Polyethylene Glycol 1000 Succinate-TPGS, Sooft Italia, Montegiorgio, Italy), was tested in vitro on six reference strains by time-killing assays. Viable cells were evaluated after 1, 15, 30 min; 2, 6, and 24 h exposure by seeding 100 µl of the suspension (or appropriate dilutions) on LB agar or Sabouraud-dextrose agar. All plates were incubated at 37 °C for 24 h and evaluated by manually counting the colonies. RESULTS: IODIM solution showed a very rapid microbicidal activity: the number of viable cells for all the tested strains was under the detection limit (less than 10 CFU/ml) already after 1 min exposure, and this result was maintained at every incubation time. The rapid antimicrobial activity of povidone-iodine was not replicated when testing the other two antiseptics. CONCLUSIONS: The study reports the great efficacy in reducing bacterial load in a very short time of povidone-iodine 0.6% compared with other antiseptic preparations.

RESUMO

PURPOSE: To evaluate the surface profile of a new-generation extended range-of-vision intraocular lens (IOL) and to compare it with that obtained for a monofocal IOL based on the same platform. METHODS: Prospective, experimental, laboratory study comparing the surface profile of the DFT015 (AcrySof IQ Vivity; Alcon Laboratories, Inc.), a new-generation presbyopia-correcting IOL, with the profile of the SN60WF (AcrySof IQ; Alcon Laboratories, Inc.), an aspheric monofocal IOL based on the same platform. Raw profiles were obtained using contact profilometry. The best-fit form was then subtracted from each raw profile to highlight potential differences. RESULTS: No significant differences were appreciated in raw profiles. On the contrary, after form removal, the new extended range-of-vision IOL showed a peculiar profile characterized by the presence of two altitudinal symmetrical changes in the order of 1 µm, localized in the central portion of the optic. CONCLUSIONS: The new-generation extended range-of-vision IOL evaluated showed a smooth change of its surface compared to the same platform monofocal IOL. The altitudinal changes blended in the central design of the new presbyopia-correcting IOL, although micrometric, might play a crucial role in creating a continuous focal range while minimizing visual disturbances.

RESUMO

PURPOSE: To evaluate in a large sample of patients from 10 different European centers the results of cataract surgery, characterizing the relationship between patient-reported outcomes (PROMs) and clinician-reported outcome measures (CROMs). METHODS: Prospective non-interventional multicenter observational descriptive study analyzing the clinical outcomes of a total of 3799 cases undergoing cataract surgery (mean age: 72.7 years). In all cases, the cataract surgery standard developed by the International Consortium for Health Outcomes Measurements (ICHOM) was used to register the clinical data. Three-month postoperative visual acuity and refraction data were considered CROMs, whereas Rasch-calibrated item 2 (RCCQ2) and total Catquest-9SF score (CQ) were considered PROMs. RESULTS: Postoperative corrected distance visual acuity (CDVA) was 0.3 logMAR or better in 88.7% (2505/2823) of eyes. Mean differences between preoperative and postoperative RCCQ2 and CQ scores were -3.09 and -2.39, respectively. Visual function improvement with surgery was reported by 91.5% (2163/2364) of patients. Statistically significant, although weak, correlations of postoperative CDVA with postoperative refraction, PROMs, and complications were found (0.133 ≤ r ≤0.289, p < 0.001). A predictive model (R2: 0.254) of postoperative CDVA considering 10 variables was obtained, including preoperative CDVA, different ocular comorbidities, age, gender and intraoperative complications. Likewise, another predictive model (R2: 0.148) of postoperative CQ considering a total of 14 variables was obtained, including additionally preoperative CQ, target refraction and previous surgeries. CONCLUSIONS: Cataract surgery provides an improved functional vision in most of patients although this improvement can be limited by ocular comorbidities and complications. The relationship between PROMs and CROMs is multifactorial and complex.

RESUMO

PURPOSE: To evaluate the vitreous concentration of different nonsteroidal anti-inflammatory drugs (NSAIDs) after topical administration and the related prostaglandin E2 (PGE2) levels in patients undergoing pars plana vitrectomy. METHODS: A prospective, randomized, investigator-masked study was performed. One hundred four patients scheduled for a pars plana vitrectomy for an epiretinal membrane or a macular hole were randomized to receive topical diclofenac 0.1%, indomethacin 0.5%, nepafenac 0.3%, bromfenac 0.09%, or placebo 3 days before surgery. At the beginning of surgery, a sample of undiluted vitreous was collected in each patient to assess NSAIDs concentration and PGE2 levels. RESULTS: The median vitreous concentrations were 203.35 (interquartile range 146.54-264.18) pg/mL for diclofenac, 243.45 (interquartile range 156.96-365.37) pg/mL for nepafenac, 438.21 pg/mL (interquartile range, 282.52-645.87) for its active metabolite amfenac, 350.14 (interquartile range, 290.88-481.95) pg/mL for indomethacin, and 274.59 (245.43-358.25) pg/mL for bromfenac. Vitreous PGE2 levels were significantly lower for all the NSAIDs groups compared with the control group (P < 0.001). A statistically significant higher vitreous PGE2 level was found in the diclofenac group compared with the other NSAIDs groups (P < 0.05). CONCLUSION: Topical NSAIDs achieve sufficient vitreous concentration to decrease vitreous PGE2 levels compared with the control group. The different efficacy in reducing PGE2 concentration may affect the management of posterior segment inflammation.

RESUMO

PURPOSE: To evaluate possible surface alterations of different models of one-piece foldable acrylic intraocular lenses (IOLs) after folding and ejecting process through 2.2-mm microincisional cataract surgery (MICS) cartridges. METHODS: In this experimental laboratory study, the following IOLs were studied: Johnson&Johnson PCB00, HOYA iSert 251, Alcon AcrySof IQ SN60WF, Bausch&Lomb enVISTA MX-60. A total of 80 IOLs were analyzed. Twenty intraocular lenses of each type were studied: ten with a power of + 21 D ± 1 and ten with a power of + 28 D ± 1. IOLs were injected through a dedicated 2.2-mm MICS cartridge into a 50-mL vial containing 10 mL of deionized water. After rinsing and metallization process, scanning electron microscopy images were acquired. RESULTS: All IOLs presented high-quality construction biomaterials. Some IOLs showed superficial scratches and tears on the optic surface, mainly positioned according to the direction of the stress induced by the folding process. In other cases, small superficial tears were seen in a more peripheral position. CONCLUSIONS: All lenses showed excellent surface quality. After folding and injection process some superficial scratches and tears of the IOL optic were detected in some models. Further studies are needed to assess the possible effects of those superficial damages on the optical quality of the IOLs.

RESUMO

PURPOSE: To investigate long-term intraocular pressure trends after uncomplicated pars plana vitrectomy for idiopathic epiretinal membrane. METHODS: Three hundred and sixty-eight eyes of 368 consecutive patients were enrolled. Changes in intraocular pressure 1, 3, 6, and 12 months after surgery and during the final follow-up visit were evaluated in vitrectomized eyes and nonvitrectomized fellow eyes. RESULTS: The median follow-up period was 36 months (range 12-92 months). Longitudinal data analysis evidenced a 2.5-mmHg (2.2 mmHg; 2.7 mmHg, 95% confidence interval) statistically significant difference in intraocular pressure 30 days after surgery between treated and fellow untreated eyes, gradually recovering to a not significant 0.2-mmHg (-0.1 mmHg; 0.4 mmHg, 95% confidence interval) difference within 26 months. The incidence of late-onset ocular hypertension was 5.7% (21 over 347, 2%; 12%, 95% confidence interval) without difference between the treated eyes and the group control. No significant difference in the incidence of late-onset ocular hypertension and sex, lens status, or gauge of vitrectomy instruments was detected. Only patient's age was significantly higher (mean difference 4.2 years; 0.1-8.0 years, Monte Carlo, 95% confidence interval) in those who developed late-onset ocular hypertension in the vitrectomized eye. CONCLUSION: Uncomplicated pars plana vitrectomy for idiopathic epiretinal membrane seems not to increase the risk of late-onset ocular hypertension or open-angle glaucoma development.

RESUMO

BACKGROUND: Digital retinal imaging is the gold standard technique for diabetic retinopathy (DR) and diabetic macular oedema (DME) assessment during DR screening. OBJECTIVES: To evaluate the diagnostic accuracy of digital retinal fundus image (DRFI) analysis in detecting DME using three manual grading systems (MGS) and comparing it with optical coherence tomography (OCT) findings. METHOD: A total of 287 DRFI of 287 eyes were analysed. Non-stereoscopic 45° images were acquired using a Kowa VX-20 camera and were graded according to three MGS: Early Treatment Diabetic Retinopathy Study (ETDRS), International Clinical Diabetic Retinopathy (ICDR), and United Kingdom National Screening Committee (UKNSC). The two graders were masked to the patient's clinical DR status. DME characteristics were analysed using OCTs. RESULTS: A very good agreement in detecting DME was found with Cohen's κ = 0.83 (ICDR vs. ETDRS), κ = 0.83 (ICDR vs. UKNSC), and κ = 0.82 (ETDRS vs. UKNSC). Sensitivity and specificity of DRFI analysis in DME assessment were 70.0 and 69.6% for UKNSC, 71.9 and 67.4% for ETDRS, and 70.9 and 65.2% for ICDR, respectively. Positive and negative predictive values were 91.7 and 32.7% for UKNSC, 91.4 and 33.3% for ETDRS, and 90.7 and 31.9% for ICDR, respectively. On OCT scans, micro-architectural damages of both inner and outer retinal layers and mean ganglion cell layer thickness showed a significant association with the presence of DME detected with DRFI analysis. CONCLUSIONS: Despite the low negative predictive value, the good specificity and sensitivity of DRFI in detecting DME make it a useful tool in a routine clinical setting, and its potential in diabetic eye screening is yet to be realized.

RESUMO

PURPOSE: To evaluate anatomical and functional outcomes after autologous neurosensory retinal free patch (ANRFP) transplantation for persistent idiopathic full-thickness macular hole (iFTMH). METHODS: A 65-year-old woman with persistent macular hole in her right eye after previous 27-gauge pars plana vitrectomy with internal limiting membrane peeling and long-acting gas tamponade underwent ANRFP transplantation. Before surgery, best corrected visual acuity in her right eye was 20/800. Optical coherence tomography (OCT) showed a 715-micron-diameter FTMH. To treat the persistent FTMH, a small autologous neurosensory retinal patch was transplanted and placed inside the macular hole under perfluorocarbon liquids (PFCL). PFCL-air exchange was performed, and long-acting gas tamponade was carried out. Clinical features of the macular area, visual acuity (VA), fundus autofluorescence, microperimetry and OCT were recorded during the 10-month follow-up. RESULTS: The macular hole appeared successfully closed with retinal patch stable and well plugged into the hole during the whole follow-up. VA improved to 20/100 and microperimetry revealed an increase in mean retinal sensitivity from 14.7 dB at 1 month to 15.6 dB at 10 months postoperatively. OCT showed a well-distinguishable retinal patch into the hole 1 month after surgery and a completely integrated retinal patch between the retinal layers 10 months postoperatively. No intra- and postoperative complications were noticed. CONCLUSIONS: ANRFP transplantation may represent an innovative technique for persistent iFTMH treatment.

RESUMO

PURPOSE: To describe the macroscopic characteristics of the subretinal fluid (SRF) and its spilling modality during evacuative puncture in scleral buckling (SB) surgery for rhegmatogenous retinal detachment. METHODS: We retrospective reviewed all the SB surgeries performed over a period of 26 months at the University Eye Clinic of Trieste, Italy. We selected a cohort of 102 patients in which SRF drainage by means of evacuative puncture was performed. A high-definition video was recorded during the whole duration of the procedures, and the macroscopic characteristics of the SRF leakage were assessed. RESULTS: Pigmented dark-brownish deposits spilling in the fluid outcoming from the evacuative puncture was observed during the surgeries. In all cases, this macroscopic feature was detected during the late phases of the drainage. Moreover, indirect ophthalmoscopic evaluation showed the almost complete SRF drainage and a flattened retina at that moment. CONCLUSIONS: The pigment stream sign, easily detectable by the surgeon, allows to understand, during the evacuative puncture, when the SRF has been drained almost completely and that the drainage procedure is therefore close to the end.

RESUMO

PURPOSE: To report on the combined use of trypan blue (TB) and brilliant blue G (BBG) for staining the epiretinal membrane (ERM) and internal limiting membrane (ILM) during vitrectomy and to describe the histopathological findings. METHODS: 10 surgical specimens were removed from 10 eyes with macular pucker during vitrectomy using a commercially available combination of TB and BBG for ERM and ILM staining and peeling. Specimens were evaluated using light and transmission electron microscopy. RESULTS: In all cases the combination of TB and BBG was useful for identifying and delineating ERM and ILM. No complications related to the use of the dye were observed during or after surgery. Glial cells were present in all specimens. Hyalocytes were observed in 6 cases and myofibroblasts in 3 of them. In 7 cases native vitreous collagen fibrils were found on the ILM, while in 5 specimens newly formed collagen was present. No clinical evidence of toxicity was observed during the 3-month follow-up. CONCLUSION: The combined use of TB and BBG appeared to be very useful intraoperatively to improve the visualization of ERM and ILM, thus facilitating their complete removal. Anatomical and histopathological findings demonstrated the safety and the efficacy of this vital dye.

RESUMO

PURPOSE: The aim of this study was to evaluate the 9-year outcome of ranibizumab monotherapy for myopic choroidal neovascularization (mCNV). METHODS: This was a retrospective, nonrandomized, multicentric study to evaluate the long-term outcomes of mCNV treated with ranibizumab monotherapy for at least 9 years according to a strict pro re nata regimen. RESULTS: Seventeen eyes of 17 patients (12 women, mean age 57.9 ± 7.7 years) were included. The mean follow-up period was 112.4 ± 3.9 months (range 108-120). The mean difference in best-corrected visual acuity (BCVA) from baseline to the last follow-up was +1.2 ± 15.6 ETDRS letters (p = 0.004, between initial vs. 12 and 24 months). The mean total number of intravitreal injections for each patient was 1.24 ± 1.70 per year (range 2-25). No systemic adverse reactions related to the drug treatment were detected during the 9-year follow-up period. CONCLUSIONS: Long-term ranibizumab monotherapy treatment induces unchanged or better BCVA compared to baseline after a 9-year treatment in almost all eyes.

RESUMO

PURPOSE: To compare the intraoperative parameters and postoperative outcomes using two different phaco handpieces with different energy delivery systems of the same phacoemulsification machine. METHODS: One hundred and sixty eyes of 160 cataract patients were randomly assigned to 2.40 mm phacoemulsification using the AMO WhiteStar Signature® phaco system with the standard phaco handpiece (Group 1) or the Ellips FX phaco handpiece (Group 2). According to the lens opacities classification system III, each group was divided into four subgroups of 20 patients each. U/S total time (UST), total phaco time (TPT), mean effective phaco time, cumulative dissipated energy (CDE) and balanced salt solution (BSS) consumption were studied. Visual acuity, corneal endothelium cell count and corneal pachymetry were evaluated before surgery and 1, 7 and 30 days after surgery. RESULTS: No statistically significant difference in terms of visual acuity was observed between the two groups. The postoperative endothelial cell loss and corneal pachymetry were similar between the two groups. In higher density cataracts, Ellips FX showed the lower CDE and the lowest UST. TPT and BSS consumption were significantly lower in the Ellips FX handpiece group. CONCLUSIONS: The two phaco handpieces appeared to be safe. AMO Ellips FX handpiece showed better performances and may be safer in lens removal, especially in hard cataract patients.

RESUMO

The aim of this study was to investigate retinal and choriocapillaris vessel changes in diabetic macular edema (DME) after the intravitreal dexamethasone implant (IDI) using optical coherence tomography angiography (OCTA). Moreover, a comparison between morphological and functional parameters of DME and healthy patients was performed. Twenty-five eyes of 25 type 2 diabetic retinopathy patients complicated by macular edema (DME group) and 25 healthy subjects (control group) were enrolled. Superficial capillary plexus density (SCPD) and deep capillary plexus density (DCPD) in the foveal and parafoveal areas, choricapillary density (CCD) and optic disc vessel density (ODVD) were detected using OCTA at baseline and after 7, 30, 60, 90 and 120 days post injection. Best corrected visual acuity (BCVA), retinal sensitivity, and central retinal thickness (CMT) were also evaluated in both groups of patients. A statistically significant difference between the two groups (DME and controls) was found in terms of functional (MP, p < 0.001 and BCVA, p < 0.001) and morphological (CMT, p < 0.001; SCPD in the parafoveal area, p < 0.001; DCPD in the foveal area, p < 0.05 and parafoveal area, p < 0.001; CCD, p < 0.001) parameters. After the treatment, SCPD and DCPD in the foveal and parafoveal areas did not modify significantly during the follow up.

RESUMO

AIM: To investigate the association of diet and other modifiable risk factors with the prevalence of age-related macular degeneration (ARMD) in rural and urban communities of a Mediterranean population in the northeast of Italy. METHODS: A cross-sectional population-based study was conducted among subjects aged over 60 years. A food frequency questionnaire (FFQ) was used to assess the consumption of different food categories, i.e., protective (P), risky (R), lutein-rich (L) and neutral (N). Smoking habit and alcohol intake were also examined. Macular pigment was measured by Raman spectroscopy. RESULTS: P food intake reduced the risk of large drusen (ARM2; OR 0.93; 95% CI 0.89-0.96) within the rural community. In this sub-group, R foods resulted in a slight association with large drusen, though the R/P food ratio was highly correlated with ARM2 (OR 1.21; 95% CI 1.12-1.31). Raman measures showed an age-dependent decrease but did not correlate with lutein intake. Smoking habit showed a positive association with ARM2 among women (OR 2.40; 95% CI 1.54-3.75), whereas alcohol consumption resulted in protective odds (OR 0.72; 95% CI 0.60-0.86). CONCLUSION: FFQ analysis confirmed the role of P and R foods and the benefit of a Mediterranean diet in ARMD. Moderate alcohol consumption showed a beneficial effect, whereas the deleterious role of a smoking habit was more evident in females.

RESUMO

To report long-term outcomes of brolucizumab in neovascular age-related macular degeneration (nAMD) treatment. Records from 74 patients were retrospectively reviewed. Both naïve eyes and those previously treated with other antiVEGF agents were included. Primary outcomes included variation in best corrected visual acuity (BCVA), central subfield thickness (CST), intraretinal fluid (IRF), subretinal fluid (SRF), and pigment epithelial detachment (PED) dimensions. Outcomes were reviewed after the loading phase, at week 24, and at last follow-up. IOI occurrence represented the secondary outcome. BCVA improved significantly in both groups. In switched eyes, IRF and SRF were significantly reduced at every timepoint, with CST reduction from week 24 (p = 0.005). In naïve group, CST decreased from the loading phase (p = 0.006) and all patients showed dry macula from week 24. A significant reduction in PED maximum high was demonstrated in both groups. In seven naïve eyes, PED completely reabsorbed; a slight increase in PED horizontal maximal diameter was also observed from week 24. IOI occurred in 5.4% of cases. In conclusion, brolucizumab showed a strong drying effect, permitting functional improvement together with fluid reabsorption and an encouraging modification of PED dimension, especially on naïve patients. These results together with the extension of treatment intervals make brolucizumab an efficient therapeutic strategy for nAMD.
