Abstract
PURPOSE Analyze the peripheral vitreoretinal interface with widefield optical coherence tomography. METHODS Retrospective chart analysis and widefield optical coherence tomography in 120 consecutive cases of rhegmatogenous pathology. RESULTS There were 166 lesions in 120 eyes, including 106 horseshoe tears, 22 operculated holes, 30 nonoperculated holes, six giant tears, and two peripheral lamellar defects followed for 6.1 ± 1.2 months. Posterior vitreous detachment was present in all eyes (101/101, 100%) with tears and operculated holes, but only in 5/19 eyes (26.3%) with nonoperculated holes ( P < 0.001). Axial vitreous traction was evident at the anterior edge of horseshoe tears (106/106, 100%), but not the posterior border (18/106, 17%, P < 0.001). Operculated holes located posterior to the vitreous base were free from vitreous traction, displaying a morphology similar to the macular hole. Nonoperculated holes were farther anterior with signs of tangential traction in 23/30 (76.7%) cases. Peripheral vitreoschisis was more often associated with nonoperculated holes (25/30, 83.3%), than horseshoe tears (17/106, 16%; P < 0.001). Horseshoe tears and nonoperculated holes were more often associated with retinal detachment (58/106 [54.7%] and 15/30 [50%], respectively) than operculated holes (5/22, 22.7%), P = 0.023. CONCLUSION Peripheral vitreoretinal interactions are similar to vitreomaculopathies, with axial and vitreoschisis-related tangential traction playing different roles in different rhegmatogenous pathologies. Peripheral optical coherence tomography improves understanding of pathophysiology and risks of retinal detachment.

The suprachoroidal space in patients affected by retinitis pigmentosa. ARCHIVOS DE LA SOCIEDAD ESPANOLA DE OFTALMOLOGIA 2024; 99:3-8. [PMID: 37813186 DOI: 10.1016/j.oftale.2023.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 08/28/2023] [Indexed: 10/11/2023]
Abstract
BACKGROUND AND OBJECTIVE The Suprachoroidal Space (SCS) is a theoretical structure which can be demonstrated between the inner border of the sclera and the outer boundary of the choroid. SCS is being studied for its potential uses as a route for drug delivery and innovative surgical techniques for the treatment of many retinal diseases. Retinitis pigmentosa (RP) is a group of inherited eye disorders characterized by a gradual loss of photoreceptors, resulting in vision impairment, which typically presents as night blindness and progressive visual field loss. The purpose of the study is to define the morphology of outer choroidal margins by means of SS-OCT in RP. MATERIAL AND METHOD This is a retrospective observational study designed to evaluate the presence of SCS in RP. We performed Swept Source optical coherence tomography (SS-OCT) in a group of 55 patients affected by RP (26 males and 29 females, 110 eyes) with a mean age of 51.8 ± 13.7 years. In the control group, we included 28 healthy subjects (6 males and 22 females, 56 eyes) with a mean age of 48,8 ± 16,6 years. RESULTS OCT scans allowed the outer choroidal margin and inner scleral margin to be delineated with certainty in all 110 eyes. In the RP group SCS was detected in 47 of 110 eyes (42,7%), in the control group SCS was detected in 11 eyes (19,6%). Subjects with SCS visible (RP group) had reduced retinal thickness (168.4 µm) compared to those with not visible SCL (211.2 µm, P = .007). CONCLUSIONS SS-OCT can be successfully applied to assess the presence of SCS in RP and the high rate of SCS found in the RP patients is encouraging when considering future innovative therapies.

Recovery of bacillary layer detachment associated with macula-off rhegmatogenous retinal detachment: Evidence of foveation mechanisms? Am J Ophthalmol Case Rep 2023; 32:101923. [PMID: 37693691 PMCID: PMC10482997 DOI: 10.1016/j.ajoc.2023.101923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 07/20/2023] [Accepted: 08/22/2023] [Indexed: 09/12/2023] Open
Abstract
Purpose To describe the mechanisms of postoperative foveal restoration in three patients with bacillary layer detachment (BALAD) associated with macula-off rhegmatogenous retinal detachment. Observations BALAD associated with macula-off rhegmatogenous retinal detachment presented with two different morphologies: with an intact foveal roof (case 1) and lamellar, with an open foveal roof (cases 2 and 3). In case 1 visual acuity significantly improved and foveal morphology completely restored at postoperative month 6, with a marked increase in foveal thickness. Case 2 presented with a lamellar BALAD in a long-standing retinal detachment, and it was treated with scleral buckling with an unfavourable evolution into a full-thickness hole in the early postoperative period. It was then addressed with internal limiting membrane peeling and inverted flap, which resulted in the resolution of the lesion, but with limited postoperative visual and anatomical recovery. Case 3 lamellar BALAD was directly addressed with pars plana vitrectomy, ILM peeling and inverted flap, with a remarkable foveal anatomical restoration and visual acuity improvement over the follow-up period. Conclusions and importance The process of foveation may play a key role in the healing process of BALAD associated with rhegmatogenous retinal detachment. Lamellar BALAD should be considered and treated as a FTMH associated with retinal detachment. The two BALAD subtypes may represent different clinical stages of the BALAD spectrum.

Risk of retinal vein occlusion following COVID-19 vaccination: a self-controlled case series. Eye (Lond) 2023; 37:3000-3003. [PMID: 36813998 PMCID: PMC9945824 DOI: 10.1038/s41433-023-02459-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 01/20/2023] [Accepted: 02/15/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND To evaluate the association between COVID-19 vaccination and retinal vein occlusion (RVO). METHODS This multicentre self-controlled case series included patients with RVO seen in five tertiary referral centres in Italy. All adults who received at least one dose of the BNT162b2, ChAdOx1 nCoV-19, mRNA-1273 or Ad26.COV2.S vaccine and had a first diagnosis of RVO between January 01, 2021, and December 31, 2021 were included. Incidence rate ratios (IRRs) of RVO were estimated using Poisson regression, comparing rates of events in a 28-day period following each dose of vaccination and in the unexposed control periods. RESULTS 210 patients were included in the study. No increased risk of RVO was observed after the first dose (1-14 days IRR: 0.87, 95% CI: 0.41-1.85; 15-28 days IRR: 1.01, 95% CI: 0.50-2.04; 1-28 days IRR: 0.94, 95% CI: 0.55-1.58) and second dose of vaccination (1-14 days IRR: 1.21, 95% CI: 0.62-2.37; 15-28 days IRR: 1.08, 95% CI: 0.53-2.20; 1-28 days IRR: 1.16, 95% CI: 0.70-1.90). No association between RVO and vaccination was found in subgroup analyses by type of vaccine, gender and age. CONCLUSIONS This self-controlled case series found no evidence of an association between RVO and COVID-19 vaccination.

Enhancing Intermediate Vision in Patients Affected by Epiretinal Membrane Treated by Phaco-Vitrectomy. J Clin Med 2023; 12:5016. [PMID: 37568418 PMCID: PMC10420151 DOI: 10.3390/jcm12155016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 07/25/2023] [Accepted: 07/28/2023] [Indexed: 08/13/2023] Open
Abstract
BACKGROUND The aim of this research was to see if a refractive enhanced monofocal IOL (Eyhance IOL, IOL Abbott Medical Optics, Inc., Santa Ana, CA, USA) can provide better intermediate vision in patients undergoing phaco-vitrectomy due to cataract and epiretinal macular membrane (ERM). METHODS A nonrandomized prospective observational comparative study enrolled patients affected by cataract and ERM undergoing phaco-vitrectomy. A follow up of 6 months was established. Corrected and uncorrected visual acuity of both monocular and binocular types were assessed regarding intermediate and far distances. The CATQUEST 9-SF questionnaire was administered preoperatively and at the last follow-up. RESULTS Twenty-three eyes of twenty-three patients were enrolled, with 11 in the enhanced monofocal group. The uncorrected and corrected distance visual acuity after 6 months was not statistically different. Both monocular and binocular uncorrected intermediate visual acuity after 6 months were higher in the enhanced monofocal group (p < 0.001). The corrected intermediate visual acuity after 6 months was higher in the enhanced monofocal group (p = 0.01). The CATQUEST-9SF questionnaire showed significant differences in the variation between the preoperative condition and six-month postoperative results (p < 0.001). CONCLUSIONS This refractive enhanced monofocal IOL can provide better intermediate vision compared to a standard monofocal IOL in patients undergoing phaco-vitrectomy due to cataracts and ERM. Further studies are necessary to confirm these results.

Three-Dimensional Visualization System for Vitreoretinal Surgery: Results from a Monocentric Experience and Comparison with Conventional Surgery. Life (Basel) 2023; 13:1289. [PMID: 37374072 DOI: 10.3390/life13061289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 05/11/2023] [Accepted: 05/24/2023] [Indexed: 06/29/2023] Open
Abstract
PURPOSE To describe the experience of our centre (Careggi University Hospital, Florence, Italy) in using a heads-up three-dimensional (3D) surgical viewing system in vitreoretinal surgery, making a comparison with the conventional microscope surgery. METHODS We retrospectively analyzed data taken from 240 patients (240 eyes) with surgical macular diseases (macular hole and epiretinal membrane), retinal detachment or vitreous hemorrhage who underwent vitreoretinal surgeries, by means of the NGENUITY 3D Visualization System (Alcon Laboratories Inc., Fort Worth, TX, USA), in comparison with 210 patients (210 eyes) who underwent vitreoretinal surgeries performed using a conventional microscope. All surgeries were performed with standardized procedures by the same surgeons. We analyzed data over a follow-up period of 6 months, comparing the surgical outcomes (best-corrected visual acuity, anatomical success rate and postoperative complication rate) between the two groups. RESULTS the 3D group included 74 patients with retinal detachment, 78 with epiretinal membrane, 64 with macular hole and 24 with vitreous hemorrhage. There were no significant differences in the demographic and clinical characteristics between the 3D group and the conventional group. We found no significant differences in outcome measures at three and six months follow-up between the two groups (p-value ≥ 0.05 for all comparisons). Surgery durations were similar between the two groups. CONCLUSIONS In our experience, a heads-up 3D surgical viewing system provided comparable functional and anatomical outcomes in comparison with conventional microscope surgery, proving to be a valuable tool for vitreoretinal surgery in the treatment of different retinal diseases.

Abstract
INTRODUCTION Non-infectious uveitis related to systemic inflammatory diseases represents a leading cause of blindness. Anti-TNFα agents are the first-line biologic therapy after traditional immunosuppressants, both for the control of ocular and systemic involvement. However, a subgroup of patients fails anti-TNFα agents, due to primary inefficacy, loss of efficacy or adverse events. AREAS COVERED This systematic review summarizes current evidence on the efficacy and safety of non-anti-TNFα biologics in adult patients with non-infectious uveitis associated with systemic inflammatory diseases. The systematic review of PubMed and Embase yielded 3663 records, from which 16 studies were included (13 non-controlled, 3 controlled trials). Most studies focused on Behçet's syndrome (BS) and juvenile idiopathic arthritis (JIA) and assessed the efficacy of tocilizumab (n=11), rituximab (n=3), secukinumab (n=1), or anakinra/canakinumab (n=1). A body of evidence supports the use of tocilizumab BS and JIA-associated uveitis, for improving visual acuity, reducing central macular thickness, inducing ocular remission, and sparing corticosteroids. Preliminary data suggest that rituximab may represent a valid alternative, particularly in JIA, while anakinra/canakinumab might play a role in BS-associated uveitis. Conversely, the role of secukinumab appears limited. EXPERT OPINION Current evidence encourages further investigations on the efficacy and safety of non-anti-TNFα agents in non-infectious non-idiopathic uveitis.

Surgical classification for large macular hole: based on different surgical techniques results: the CLOSE study group. Int J Retina Vitreous 2023; 9:4. [PMID: 36717928 PMCID: PMC9885593 DOI: 10.1186/s40942-022-00439-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 12/29/2022] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND The CLOSE study group proposes an updated surgical classification for large macular holes based on a systematic review of new treatments. Recently, many new techniques have been introduced to treat large full-thickness macular holes (FTMH); although the indications are not clear. An updated surgical classification is needed to help surgical decision-making. METHODS We gathered published series by the CLOSE Study Group members and from literature search until June 2021. Techniques included: internal limiting membrane peeling (ILM peeling), ILM flaps, macular hydrodissection (macular hydro), human amniotic membrane graft (hAM), and autologous retinal transplantation (ART). Within each technique, chi-square test assessed association between the minimal linear diameter (MLD) (in µm) and closure rate; the postoperative best-corrected visual acuity (BCVA) gains were compared among groups. RESULTS Data extraction included 31 published articles: total of 1135 eyes. Eyes were divided into the following groups: ILM peel (n: 683), ILM Flap (n: 233), macular hydrodissection (n: 64), hAM (n: 59), and ART (n: 96). The initial BCVA and size were heterogenous between the groups. ILM peel showed the best results in large FTMH ≤ 535 µm (closure rate 96.8%); adjusted mean BCVA: 0.49 (LogMAR) with a statistical difference among groups. Large FTMH between 535 and 799 µm: ILM flap technique showed better results (closure rate 99.0%); adjusted mean BCVA: 0.67(LogMAR); also with a statistical difference. For large FTMH ≥ 800 µm more invasive techniques are required. Use of hAM, macular hydrodissection and ART showed higher closure rates for this category (100%, 83.3% and 90.5% respectively), and adjusted mean BCVA varied from 0.76 to 0.89. Although there was no statistical difference between those techniques for this group due to the smaller number of cases. CONCLUSIONS The CLOSE study group demonstrated the potential usefulness of a new surgical classification for large FTMHs and propose OCT biomarkers for use in clinical practice and future research. This new classification demonstrated that Large (400-550 µm) and X-Large (550-800 µm) holes can be treated highly successfully with ILM peel and ILM flap techniques, respectively. Further studies are necessary for the larger FTMHs (XX-Large and Giant), using the CLOSE classification, in order to determine which technique is better suited for each hole size and characteristics.

Scanning Laser Ophthalmoscopy Retromode Imaging Compared to Fundus Autofluorescence in Detecting Outer Retinal Features in Central Serous Chorioretinopathy. Diagnostics (Basel) 2022; 12:2638. [PMID: 36359481 PMCID: PMC9689095 DOI: 10.3390/diagnostics12112638] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 10/19/2022] [Accepted: 10/24/2022] [Indexed: 07/24/2023] Open
Abstract
Central serous chorioretinopathy (CSCR) is a retinal disease characterized by a heterogeneous clinical phenotype, depending on the influence of different factors in its pathogenesis, including the presence of subretinal fluid (SRF), trophism of the retinal pigmented epithelium (RPE) and choroidal hyper-permeability. Our study has the purpose of assessing the ability of scanning laser ophthalmoscopy (SLO) retromode imaging, compared to fundus autofluorescence (FAF), to identify outer retinal features in a cohort of patients with a diagnosis of CSCR. A total of 27 eyes of 21 patients were enrolled in our study. All patients underwent full ophthalmological examination, including fundus retinography, fundus fluorescein angiography, optical coherence tomography (OCT), FAF and SLO retromode imaging. For each patient, the following features were evaluated: SRF, the presence of pigmented epithelium detachment (PED), RPE dystrophy, and RPE atrophy. RPE dystrophy was further characterized according to the appearance in FAF of iso-, hyper- and hypo-autofluorescent dystrophy. The ability to identify each feature was evaluated for FAF and SLO retromode alone, compared to a multimodal imaging approach. FAF identified SRF in 11/14 eyes (78%), PED in 14/19 (74%), RPE dystrophy with iso-autofluorescence in 0/13 (0%), hyper-autofluorescence in 18/19 (95%), hypo-autofluorescence in 20/20 (100%), and RPE atrophy in 7/7 (100%). SLO retromode imaging identified SRF in 13/14 eyes (93%), PED in 15/19 (79%), RPE dystrophy with iso-autofluorescence in 13/13 (100%), hyper-autofluorescence in 13/19 (68%), hypo-autofluorescent in 18/20 (90%), and RPE atrophy in 4/7 (57%). SLO retromode imaging is able to detect retinal and RPE changes in CSCR patients with a higher sensitivity than FAF, while it is not able to identify the depth of lesions or supply qualitative information about RPE cells' health status, meaning that it is less specific. SLO retromode imaging may have a promising role in the assessment of patients with CSCR, but always combined with other imaging modalities such as OCT and FAF.

Abstract
BACKGROUND AND OBJECTIVE Retromode scanning laser ophthalmoscopy (RM-SLO) is a new imaging modality displaying pseudo-3D retinal images. We assessed the correlation between the morphological features of full-thickness macular holes (FTMHs) when using spectral domain-optical coherence tomography (SD-OCT) and when using RM-SLO. MATERIALS AND METHODS This is a prospective observational case series in which patients were examined through SD-OCT and RM-SLO after informed consent was obtained. Intraclass correlation coefficient (ICC) and Pearson correlation coefficient (PCC) were used to assess interobserver agreement and the correlation between the diameters measured with the two techniques. RESULTS We enrolled 20 patients (20 eyes) with an average hole aperture size of 426 μm (140-890 μm) on SD-OCT and 56 pixels (19-102 pixels) on RM-SLO. ICC and PCC were 0.999 and 0.992, respectively. "Standard" and "double-ring" FTMH patterns were described on RM-SLO and related well with SD-OCT findings. CONCLUSIONS RM-SLO is a reliable method for FTMH-diameter evaluation and identifies unique pseudo-3D morphological features consistent with their B-scan counterparts.

Comparative analysis of macular microstructure in eyes treated with human amniotic membrane plug or internal limiting membrane transplant for Failed Macular Hole. Acta Ophthalmol 2022; 100:e1031-e1035.

Abstract
OBJECTIVE To document comparative analysis of macular microstructures of eyes treated with autologous internal limiting membrane (ILM) transplant and human Amniotic Membrane (hAM) plug transplant for failed macular holes (FMH). MATERIALS AND METHODS Six patients who underwent successful surgeries for FMH were evaluated. The first three patients had undergone autologous ILM transplant, the others had undergone hAM plug transplant. They were examined using Adaptive Optics (AO) at baseline and at 6 months after surgery; OCT and OCT-Angiography were performed at 6 months. All images were evaluated morphologically; AO images were also analysed using the internal software. RESULTS Regarding the AO analysis in ILM-patients, the average cone density inside the lesion was 7684.44 ± 362.96 and the total spacing was 10.86 ± 0.97. In hAM-patients, the average cone density inside the plug area was 10197.9 ± 326.62 and the total spacing was 10.6 ± 0.72. It was not possible to analyse cone density in the area outside the lesion on any patients. All patients were also evaluated morphologically. OCT analysis in ILM-patients showed a subverted anatomical situation, while in hAM-patients revealed the regrowth of tissue layers and a resumption of foveal depression. OCT-Angiography analysis revealed an enlargement of the FAZ in ILM-patients and a fairly normal appearance and size of the FAZ in hAM-patients, in comparison to the fellow eye. CONCLUSIONS Our findings require validation with a longer follow-up in a larger quantity of patients, but already suggest important differences in the cellular mechanism that underlies the tissue remodelling in these two techniques.

Abstract
Purpose: We investigated the chorioretinal microvascular changes in patients with retinitis pigmentosa (RP) by optical coherence tomography angiography (OCTA). Methods: Twenty-six patients (52 eyes) affected by RP were compared with 19 healthy controls (38 eyes). OCTA 3 mm × 3 mm macular scans were performed in all subjects. We evaluated the vessel density (VD) of the superficial capillary plexus (VD SCP), deep capillary plexus (VD DCP), choriocapillaris (VD CC), and choroid (VD choroid). We also evaluated the foveal avascular zone (FAZ) area, and the correlation between clinical and OCTA parameters. We also measured central retinal thickness (CRT) and subfoveal choroidal thickness (CT). Results: RP patients compared to healthy controls showed significantly lower VD SCP values (27.56% ± 15.37 vs. 49.39% ± 1.55; p-value < 0.0001), lower VD DCP values (38.43% ± 15.23 vs. 3.34% ± 0.26; p-value < 0.0001), lower VD CC values (46.02% ± 1.293 vs. 50.63% ± 0.4274; p-value = 0.0040), and lower VD choroid values (38.48% ± 15.23 vs. 3.34% ± 0.26; p-value < 0.0001). Even the FAZ area was significantly lower in RP patients (0.45 mm2 ± 0.35 vs. 0.26 mm2 ± 0.13; p-value < 0.0001). The FAZ area was larger with increasing age, both in control (r = 0.42; p = 0.012) and RP group (r = 0.46; p-value = 0.009). In RP patients, there was a statistically significant correlation between best-corrected visual acuity and VD SCP (r = 0.24, p-value = 0.04) and VD DCP (r = 0.52; p-value = 0.0004) and between subfoveal choroidal thickness and VD SCP (r = 0.43, p-value < 0.001) and VD DCP (r = 0.35, p-value < 0.001). Conclusions: In our study, OCTA reported relevant vascular alterations in RP patients in comparison with the healthy controls, in agreement with the published literature. These abnormalities were associated with choroidal atrophy and related to visual acuity loss. OCTA provided clinically significant information and may represent a reliable tool for the management of RP patients.

Abstract
PURPOSE To describe features of uveitis-glaucoma-hyphema (UGH) syndrome, using Anterior Segment-Optical Coherence Tomography (AS-OCT) and Ultrasound Biomicroscopy (UBM) and to evaluate the diagnostic role of AS-OCT as an imaging technique alternative to UBM. DESIGN Retrospective case series. METHODS Four eyes of 4 patients with UGH syndrome were analyzed. All patients reported previous uncomplicated cataract surgery with in-the-bag implantation of single-piece-intraocular lens (IOL). They underwent at presentation complete ophthalmological examination and imaging with slit-lamp anterior segment photographs, UBM and AS-OCT. RESULTS Although AS-OCT did not allow to visualize the structures behind the iris, it displayed a contact between IOL (plate and/or haptics) and iris and IOL tilting in 3 out of 4 eyes. AS-OCT directly detected the cause of UGH syndrome in one eye, 2 eyes required some expedients to display the iris chafing, like scans in mydriasis and/or patient's gaze direction change. AS-OCT did not allow to appreciate the IOL-iris contact (showed by UBM technique) only in one eye, probably due to the change of patient position from supine to sitting, and consequent anteriorization of iris diaphragm. Furthermore AS-OCT showed fine details, as capsular bag collapse and indirect signs of haptic malposition in 3 out of 4 eyes. CONCLUSION AS-OCT is a non-invasive technique that allows to determine IOL position and IOL-uveal contact in selected cases of UGH syndrome. Considering AS-OCT and UBM advantages and limitations, AS-OCT should be used as first imaging modality when clinical diagnosis is uncertain. When UGH diagnosis cannot be verified using AS-OCT, UBM should be performed.

Abstract
PURPOSE To assess the occurrence of peripheral vitreoschisis-induced vitreous cortex remnants (p-VCRs) in primary rhegmatogenous retinal detachment (RD) and investigate whether the presence of p-VCRs results in a greater risk of RD recurrence, secondary to Proliferative Vitreoretinopathy (PVR) development after pars plana vitrectomy (PPV). METHODS Patients who underwent PPV for primary rhegmatogenous RD between January 2016 and December 2018 were included. The presence of residual p-VCRs was confirmed intraoperatively using triamcinolone acetonide (TA). Patients with p-VCRs were divided into two groups: Group A comprised of patients who underwent PPV without p-VCR removal, while Group B included patients who underwent PPV with p-VCR removal. RESULTS Four hundred-thirteen eyes with evidence of p-VCR were analyzed. Two-hundred-twenty-three eyes underwent PPV without VCR removal (Group A), while 190 eyes underwent PPV with p-VCR removal (Group B). Primary anatomical success was 91.5% in the Group A and 95.4% in the group B. Retinal re-detachment due to PVR occurred in 17 (7.6%) eyes in Group A and in four (2.1%) eyes in Group B within the first 3 months (p = 0.01). Among group A, in 11 eyes, there was a diffuse posterior PVR grade C, while six eyes were focal PVR grade C. In Group B, we observed four retinal re-detachment due to focal PVR grade C. CONCLUSION The presence of p-VCRs seems to be associated with a higher incidence of PVR development and might also result in more complex RD recurrence, this suggests the need for more aggressive VCRs removal during the first surgery.

Choriocapillaris Vascular Density Changes: Healthy vs. Advanced Exudative Age-Related Macular Degeneration Previously Treated with Multiple Anti-VEGF Intravitreal Injections. Diagnostics (Basel) 2021; 11:diagnostics11111958. [PMID: 34829305 PMCID: PMC8621604 DOI: 10.3390/diagnostics11111958] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 09/30/2021] [Accepted: 10/01/2021] [Indexed: 11/28/2022] Open
Abstract
Purpose: To assess choriocapillaris vascular density (VD) in healthy and advanced exudative age-related macular degeneration (ae-AMD) patients by new full-range optical coherence tomography angiography (OCT-A). Method: In this observational, cross-sectional study, 21 healthy and 21 ae-AMD eyes, already treated with anti-VEGF, were enrolled. Angio-View retina patterns centered on fovea (6.4 × 6.4 mm) were acquired for all participants using Solix full-range OCT (Optovue Inc., Freemont, CA, USA). The main outcome was to compare choriocapillaris VD between healthy and ae-AMD eyes. Automated measurements of whole image choriocapillaris VD (%) and fovea grid-based (%) were collected for the analysis. Angio-View patterns were used to assess the flow area (mm2) of macular neovascularization (MNV) by contour flow measure algorithm. Best-corrected visual acuity (BCVA) of both groups was also used for the statistical analysis. Results: The mean age was 60.9 (±8.3) in healthy and 73.33 (±15.05) in ae-AMD eyes. The mean BCVA (ETDRS letters) was 98.47 (±1.50) in healthy and 7.04 (±5.96) in ae-AMD eyes. The Mann–Whitney test comparing choriocapillaries VD for whole and fovea healthy and ae-AMD eyes showed statistical significance (p < 0.0001 (t = 4.91; df = 40) and p < 0.0001 (t = 6.84; df = 40), respectively). Regarding, the correlation between MNV and VD of choriocapillaries, neither whole nor fovea areas were statistically significant (F = 0.38 (R2 = 0.01) and 1.68 (R2 = 0.08), respectively). Conclusions: Choriocapillaris VD showed a statistically significant reduction in comparison to healthy eyes in ae-AMD eyes. Choriocapillaris impairment can be seen in the early phase of MNV pathogenesis.

Management of submacular massive haemorrhage in age-related macular degeneration: comparison between subretinal transplant of human amniotic membrane and subretinal injection of tissue plasminogen activator. Acta Ophthalmol 2021; 100:e1143-e1152. [PMID: 34609787 DOI: 10.1111/aos.15045] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 09/08/2021] [Accepted: 09/22/2021] [Indexed: 11/29/2022]
Abstract
PURPOSE Macular neovascularization (MNV) can complicate age-related macular degeneration (AMD) and lead to severe visual acuity reduction. Massive submacular haemorrhage (SMH) is a sight-threatening complication of MNV and a challenge in the management of complications related to MNV in AMD since the effects of anti-vascular endothelial growth factor treatment alone are insufficient. Here, we evaluate the different postoperative outcomes of patients affected by MNV complicated by SMH that underwent subretinal implant of human amniotic membrane (hAM) or subretinal injection of tissue plasminogen activator (tPA). METHODS This is a retrospective, consecutive, comparative, non-randomized interventional study. We included 44 eyes of 44 patients affected by AMD complicated by MNV and SMH. Twenty-two eyes underwent a pars plana vitrectomy (PPV), SMH and neovascular membrane removal, with a subretinal implant of hAM and silicone oil, and 22 eyes underwent PPV, subretinal injection of tPA, and 20% sulphur hexafluoride. The primary study outcome was visual acuity improvement. Secondary outcomes were postoperative complications, and MNV recurrence and optical coherence tomography (OCT)-Angiography parameters correlated with best-corrected visual acuity (BCVA). RESULTS Mean preoperative BCVA was 1.9 logarithm of the minimal angle of resolution (logMAR) in the amniotic membrane-group and 2 logMAR in the tPA-group. The mean final BCVA values were 1.25 and 1.4 logMAR, respectively, with a statistically significant difference. Optical coherence tomography (OCT)-Angiography scan was be used to evaluate the retinal vascularization in the treated eye. CONCLUSION Both techniques report similar VA improvements and postoperative complications. However, transplantation of hAM seems to have a significant benefit in inhibiting MNV recurrence.

Abstract
Aims To compare the biometric data from partial coherence interferometry (PCI) and swept-source OCT (SS-OCT) in patients with age-related cataract and epiretinal membrane (ERM): ERM, ERM with foveoschisis and macular pseudohole. Methods 49 eyes of 49 subjects including 36 ERM, 9 ERM foveoschisis and 4 macular pseudohole were analysed to evaluate the axial length (AL) measurements and the presence of AL measurement errors, defined basing on the shape of the biometric output graphs and on the concordance of AL values between instruments. Eyes with ERM were divided in four stages according to OCT features (i.e. presence/absence of the foveal pit, presence of ectopic inner foveal layers, disrupted retinal layers). Results The devices provided similar mean AL measurements in all subgroups, with differences <0.1 mm in 41/49 cases (83.6%). AL measurement errors were observed in ERM stages 3 and 4, characterized by ectopic inner foveal layers, and were significantly more frequent with the PCI (8/17, 47%) as compared with the SS-OCT device (2/17, 12%), p = 0.02. The refractive prediction error in cases with AL measurement errors was significantly greater using the PCI compared to the SS-OCT device (p<0.05). Conclusion Both devices provide reliable biometric data in the majority of patients and can be used in the preoperative assessment of patients with age-related cataract and ERM. In eyes with ectopic inner foveal layers, attention should be paid as AL measurement and refractive prediction errors may occur, more frequently with the PCI device.

Abstract
PURPOSE To investigate the vascular remodeling of optical coherence tomography angiography in full-thickness macular hole surgery. METHODS This retrospective, observational case series included 33 eyes of 33 patients with a full-thickness macular hole who underwent epiretinal membrane removal. Data were collected on best-corrected visual acuity, structural B-scan optical coherence tomography, and optical coherence tomography angiography preoperatively and at 1, 3, and 6 months postoperatively. Optical coherence tomography angiography was used to assess the retinal vascular density (VD) of the superficial vascular plexus and deep vascular plexus (DVP). Vascular density was assessed using the Early Treatment Diabetic Retinopathy Study grid for the whole, inner, and outer grids. RESULTS A statistically significant correlation was found between the VD (whole, inner, and outer grids) of the superficial vascular plexus alone from baseline to 1-month postoperatively (P < 0.001). Similarly, VD was correlated from baseline to 1, 3, and 6 months postoperatively to the whole (P < 0.0005, F = 23.22), inner (P < 0.0005, F = 28.23), and outer Early Treatment Diabetic Retinopathy Study grids of DVP (P = 0.033, F = 3.49). The best-corrected visual acuity and VD were significantly correlated with the superficial vascular plexus and DVP at baseline and 6 months (P < 0.05, all correlations). The most significant correlation was observed at 6 months between best-corrected visual acuity and DVP in the whole, inner, and outer Early Treatment Diabetic Retinopathy Study grids (P < 0.001). CONCLUSION Superficial vascular plexus and DVP are affected by full-thickness macular holes, with the most significant effects being on the DVP. Full-thickness macular hole surgery leads to an improvement in the best-corrected visual acuity in many eyes and the restoration of the VD, especially of the DVP.

Abstract
The term amyloidosis describes a group of rare diseases caused by protein conformation abnormalities resulting in extracellular deposition and accumulation of insoluble fibrillar aggregates. So far, 36 amyloid precursor proteins have been identified, and each one is responsible for a specific disease entity. Transthyretin amyloidosis (ATTRv) is one of the most common forms of systemic and ocular amyloidosis, due to the deposition of transthyretin (TTR), which is a transport protein mainly synthesized in the liver but also in the retinal pigment epithelial cells. ATTRv amyloidosis may be misdiagnosed with several other conditions, resulting in a significant diagnostic delay. Gelsolin and keratoepithelin are other proteins that, when mutated, are responsible for a systemic amyloid disease with significant ocular manifestations that not infrequently appear before systemic involvement. The main signs of ocular amyloid deposition are in the cornea, irido-corneal angle and vitreous, causing complications related to vasculopathy and neuropathy at the local level. This review aims at describing the main biochemical, histopathological and clinical features of systemic amyloidosis associated with eye involvement, with particular emphasis on the inherited forms. We discuss currently available treatments, focusing on ocular involvement and specific ophthalmologic management and highlighting the importance of a prompt treatment for the potential sight-threatening complications derived from amyloid deposition in ocular tissues.

Optical Coherence Tomography Angiography for the Evaluation of Retinal Vasculature in Fabry Disease: Our Experience and Review of Current Knowledge. Front Neurol 2021; 12:640719. [PMID: 33767663 PMCID: PMC7985262 DOI: 10.3389/fneur.2021.640719] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 02/01/2021] [Indexed: 11/29/2022] Open
Abstract
Purpose: Optical coherence tomography angiography (OCTA) is a non-invasive and objective tool for the evaluation of the retinal microvascular changes in Fabry disease (FD). We investigated changes in retinal vasculature in FD patients, and the possible correlation with systemic parameters, by using OCTA, and reviewed the current status of literature. Methods: Thirteen FD patients (eight females, five males, mean age 49.85 ± 14.7 years) were compared with 13 age- and sex-matched healthy controls. OCTA 3 × 3 mm macular scans were performed in all subjects. We evaluated the vessel density and vessel perfusion in distinct macular areas (whole, inner, and outer) of both the superficial capillary plexus (SCP VD and SCP VP) and of the deep capillary plexus (DCP VD and DCP VP). We also evaluated the foveal avascular zone (FAZ) metrics (area, perimeter, and circularity), and correlation between systemic and OCTA parameters. A literature review on the current understanding of OCTA in FD is then presented. Results: FD patients showed significantly lower SCP VD values in the whole area (17.37 ± 2.08 mm−1 vs. 18.54 ± 1.21 mm−1; p-value 0.022), as well as in the outer area (17.46 ± 2.10 mm−1 vs. 19.08 ± 1.14 mm−1; p-value 0.002), but not in the inner. Even the DCP VD was significantly lower in all the imaged areas: whole (17.75 ± 3.93 mm−1 vs. 19.71 ± 1.20 mm−1; p-value 0.024), outer (18.25 ± 4.17 mm−1 vs. 20.33 ± 1.20 mm−1; p-value 0.023), and inner (19.54 ± 4.17 mm−1 vs. 21.96 ± 1.55 mm−1; p-value 0.011). There were no significant differences in vessel perfusion parameters (both SCP VP and DCP VP ones) and FAZ. No significant correlations were found between the OCTA parameters and systemic parameters (maximal left ventricular wall thickness and glomerular filtration rate) in FD patients. Conclusions: OCTA can be considered as a promising non-invasive tool, which enables a quantitative evaluation of retinal vascular involvement in FD, despite the varying data reported in literature. Our results support the use of OCTA as an objective tool to evaluate retinal vascular abnormalities in FD. The utility of OCTA in FD needs to be validated by longitudinal studies taking into account the overall progression of the disease.

Abstract
ABSTRACT Optical coherence tomography angiography is a relatively new noninvasive technique that is changing our approach in the management of several retinal diseases such as neovascular age-related macular degeneration, occlusive retinal diseases, or diabetic retinopathy, but it could also be useful in nonprimary vascular retinal pathologies such as vitreoretinal interface surgical disorders.In idiopathic vitreoretinal interface disorders and surgical retinal diseases, the study of vascular involvement, not commonly assessed by invasive methods, could be useful to reveal specific vascular abnormalities. Such information may be useful for a more detailed phenotyping of each clinical picture before and after surgical treatment, providing potential new prognostic biomarkers.The review discusses the current and potential utility of optical coherence tomography angiography to study vitreoretinal pathologies of surgical interest.

Abstract
Background: The aim of the study was to evaluate pre-operative and post-operative retinal vasculature using optical coherence tomography angiography (OCTA) in patients who underwent rhegmatogenous retinal detachment (RRD) surgery repair. Materials and Methods: A total of 33 eyes were included in this prospective consecutive observational study: 15 affected by macula-ON and 18 by macula-OFF RRD. Superficial (SCP), deep capillary plexus (DCP), and foveal avascular zone (FAZ) area variations were evaluated by OCTA and correlated with visual acuity (VA) during a six-month follow-up. Results: In the macula-ON group, the preoperative vascular density (VD) of the whole SCP (wSCP) on affected eyes was lower than that of the fellow eyes (p < 0.05); this difference disappeared at 6 months after surgery (p = 0.88). The wSCP VD and the parafoveal SCP (pfSCP) VD increased during follow-up (p < 0.05); moreover, the higher the preoperative wSCP and pfSCP VD, the better the baseline VA (p < 0.05). In the macula-OFF group, at the first and sixth months after surgery, the larger the FAZ, the lower the VA (p < 0.05). Conclusions: Macula-ON SCP VD affected preoperative VA, and it was lower than the fellow eye, but recovered over time. In the macula-OFF group, a larger FAZ area was related to a worse VA, as is the case in diabetes and in retinal vein occlusion (RVO).

Abstract
PURPOSE A case of bilateral choroidal metastasis from an adenoid cystic carcinoma of the submandibular gland is described. CASE DESCRIPTION A 45-years-old woman with a history of metastatic adenoid cystic carcinoma presented with visual impairment in both eyes. Fundus images showed bilateral creamy-white choroidal masses. Optical coherence tomography revealed subretinal fluid with high reflective speckles and a "lumpy bumpy" anterior contour of the lesions. Fluorescein angiography showed a hypofluorescent pattern of the lesions in early arterial phases, and progressive late hyperfluorescence. A diagnosis of bilateral choroidal metastasis from adenoid cystic carcinoma was made. The patient was advised to underwent palliative chemotherapy, but she expired a few weeks after the diagnosis. CONCLUSION Salivary gland carcinoma rarely metastasizes to the choroid, with few cases described in literature. In patients with a history of salivary glands tumor the possibility of choroidal metastatization should always be considered.

Abstract
PURPOSE We describe the characteristics of an isolated retinal cavernous hemangioma in a young female patient using multimodal imaging. CASE DESCRIPTION Fundus examination of the right eye showed a large vascular mass, composed by clusters of dark red and dilated saccular angiomatous formations with superficial whitish fibroglial tissue and hemorrhages, located in the inferonasal peripheral retina, along the vascular arcade. On green-light fundus autofluorescence the lesion appeared hypoautofluorescent, with moderately hyperautofluorescent areas. On multiColor imaging it showed mainly a green pseudocolor, with knobby surface and well-defined irregular margins. Fundus fluorescein angiography showed early hypofluorescence within the tumor mass and late incomplete staining, without leakage. Ocular ultrasonography documented an elevated well-defined hyperechogenic lesion, with high internal reflectivity, without choroidal excavation, retinal detachment, or acoustic shadowing. Swept source optical coherence tomography showed multilobulated cavernous formations, varying in size, containing for the greatest part hyperreflective material, within an interconnecting fibrous scaffold and with an overlying partially adherent epiretinal membrane. Optical coherence tomography angiography documented a few highly reflective, tortuous and abnormal branching veins extending into the tumor mass, with a root-like appearance, and surrounding nodular changes, corresponding to the angiomatous formations. CONCLUSIONS Different imaging modalities can be used in combination for a better evaluation of the pathological features of this rare vascular tumor.

Human amniotic membrane plug to promote failed macular hole closure. Sci Rep 2020; 10:18264.

Abstract
The failed macular hole is a full-thickness defect involving the fovea that fails to close despite 1 or more surgeries. While many surgical options have been proposed to manage it, none of these guarantee complete anatomical success and satisfactory visual recovery. We report postoperative outcomes on 36 patients affected by failed macular hole, treated with a human amniotic membrane plug transplant. Follow-ups were performed with a standard ophthalmological examination and with advanced multimodal diagnostic imaging. Anatomical closure was achieved at 3 months in all patients. Mean best-corrected visual acuity improved statistically significantly at 6 months (p < 0.05). Through microperimetric tests, we assessed a partial recovery of the macular sensitivity on the edges of the plug. Analyzing SD-OCT images, we reported a tissutal ingrowth above the plug, and its segmentation into layers, mimicking normal retinal architecture. OCT-Angiography images non invasively analysed the retinal parafoveal capillary microvasculature; the elaboration of Adaptive Optics images showed the presence of photoreceptors at the edges of the plug. This work demonstrates not only the complete anatomical success of our technique, but also remarkable functional results, and opens the door to a greater understanding of modifications induced by the presence of a human amniotic membrane plug.

Abstract
Drug delivery into the vitreous chamber remains a great challenge in the pharmaceutical industry due to the complex anatomy and physiology of the eye. Intravitreal injection is the mainstream route of drug administration to the posterior segment of the eye. The purpose of this review is to assess the current literature about the widening use of the intravitreal 0.7 mg dexamethasone (Dex) implant, and to provide a comprehensive collection of all the ocular disorders that benefit from Dex administration. Although anti-vascular endothelial growth-factors (VEGFs) have been largely indicated as a first-choice level, the Dex implant represents an important treatment option, especially in selected cases, such as vitrectomized eyes or patients in whom anti-VEGF failed or are contraindicated. In this article, the safety profile as well as the list of the possible complications related to intravitreal Dex injection are also discussed.

[PMID: 32344157 DOI: 10.1016/j.oret.2020.04.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Revised: 04/10/2020] [Accepted: 04/17/2020] [Indexed: 12/13/2022]
Abstract
PURPOSE Age-related macular degeneration (AMD) is the leading cause of legal blindness in adults 65 years of age and older. Choroidal neovascularization (CNV) can complicate AMD and lead to severe visual acuity reduction. Despite the several treatments available, if the retinal pigment epithelium is damaged, we have to cope with the impossibility of restoring acceptable visual acuity using only medical treatments. DESIGN Prospective, consecutive, interventional study. PARTICIPANTS Eleven patients affected by AMD, 6 patients affected by CNV, and 5 patients affected by geographic atrophy. METHODS All patients underwent a pars plana vitrectomy with subretinal implantation of human amniotic membrane (hAM) to induce photoreceptor regeneration and partial visual acuity restoration. MAIN OUTCOME MEASURES Primary study outcome was visual acuity improvement. Secondary outcomes were multimodal imaging results. RESULTS Mean preoperative best-corrected visual acuity (BCVA) was 20/2000 (2 logarithm of the minimum angle of resolution [logMAR]), and all the patients showed a BCVA of counting fingers or less. Mean final BCVA was 20/400 (1.31 logMAR), ranging from 20/2000 to 20/100 (2-0.7 logMAR). OCT angiography was used to measure retinal vascularization in the treated eye compared with the fellow eye. A high correlation between BCVA and deep vascular density was evidenced. Adaptive optics findings, obtained over the retinal area where the highest functionality was observed, were evaluated using microperimetry. The images showed possible photoreceptor presence over the hAM membrane. CONCLUSIONS This work supports the feasibility and safety of the hAM to promote partial retinal function restoration 6 months after surgery with visual acuity improvement. The advanced diagnostics help to understand the interaction between the hAM and photoreceptors and suggest that photoreceptor regeneration may occur.

Abstract
PURPOSE To assess the current role of fluorescein angiography after the introduction of optical coherence tomography angiography in real-life clinical practice. METHODS This was a multicentric retrospective observational study to evaluate the number of fluorescein angiography and optical coherence tomography angiography procedures performed by different devices from January 2013 to December 2018. The centers involved were Centro Italiano Macula (Rome), and ophthalmology departments of University "G. D'Annunzio" Chieti-Pescara (Chieti) and "Azienda Ospedaliero Universitaria Careggi" (Florence). RESULTS Out of 19,898 total fluorescein angiography procedures performed in the observation period, 3444 (17.3%) were in 2013, 3972 (19.9%) were in 2014, 3601 (18.1%) were in 2015, 3407 (17.2%) were in 2016, 3285 (16.5%) were in 2017, and 2189 (11%) were in 2018. Out of 7949 optical coherence tomography angiography procedures performed in the observation period, none were performed in 2013, 550 (6.9%) were in 2014, 908 (11.5%) were in 2015, 2098 (26.4%) were in 2016, 2090 (26.3%) were in 2017, and 2303 (28.9%) were in 2018. CONCLUSION Fluorescein angiography procedures were performed less often after the introduction of optical coherence tomography angiography technology. The ease, speed, and safety of the optical coherence tomography angiography procedure in everyday clinical practice have facilitated more optical coherence tomography angiography application compared to fluorescein angiography in recent years. In the future, we will probably evaluate the different pathologies that still need an evaluation by fluorescein angiography.

Adalimumab effectively controls both anterior and posterior noninfectious uveitis associated with systemic inflammatory diseases: focus on Behçet's syndrome. Inflammopharmacology 2020; 28:711-718. [PMID: 32157555 DOI: 10.1007/s10787-020-00697-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 02/27/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND To compare the efficacy of Adalimumab (ADA) in noninfectious anterior uveitis (AU) and posterior segment (PS) involvement, associated with different conditions, with a focus on Behçet's syndrome (BS). METHODS In this retrospective, multicenter post-hoc study, we evaluated the efficacy of ADA in terms of ocular control and relapses in 96 patients with AU and PS uveitis, either idiopathic (IU) or associated with BS or with other systemic disorders (OSD) (Juvenile Idiopathic Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, Vogt-Koyanagi-Harada, Inflammatory Bowel Disease), followed in three tertiary referral centers. RESULTS Ninety-six patients (45 AU; 51 PS uveitis) were included. Eleven had IU, 58 BS, and 27 OSD. All patients with AU achieved complete long-term ocular control. In PS uveitis, 89%, 67% and 100% of patients with BS, IU and OSD achieved ocular control at the last follow-up (> 12 months), respectively. The lowest ocular relapse rate occurred in patients with AU with BS (1/13) or IU (0/2). ADA accounted for long-term disease control, and no predictors of ocular control and relapse were identified; particularly, ocular relapses seemed not related to systemic ones. Macular edema resolved in 75% and 67% of PS uveitis with BS and IU, respectively. CONCLUSIONS ADA controls both anterior and posterior uveitis, with an efficacy similar in IU, BS and OSD patients. In BS, the efficacy of ADA seems to be independent of demographic and clinical characteristics, and ocular relapses mostly occurred independently from systemic ones. Based on our results, ADA may represent a valid alternative in anterior refractory uveitis.

Abstract
PURPOSE To compare visual outcome and postoperative complications of combined 25-gauge pars plana vitrectomy and phacoemulsification with vitrectomy alone surgery in patients with epiretinal membrane and macular hole. METHODS A total of 110 eyes (73 eyes with epiretinal membrane and 37 eyes with macular hole) were enrolled in this prospective study. The eyes were divided into two groups: Group A included 55 eyes which underwent phacovitrectomy at the same time and Group B included 55 eyes which underwent vitrectomy alone. Follow-up visits were at 1, 3, and 6 months. RESULTS The best-corrected visual acuity correlation by analysis of variance measurement showed statistically non-significant differences between the two groups (p = 0.32). The post hoc analysis from baseline, 1°, 2°, and 3° follow-ups was not statistically significant (p > 0.05). The most common postoperative complication was cystoid macular edema that has been detected in 11 patients (10%) (seven eyes in Group A and four eyes in Group B): 2 patients (1.8%) developed a chronic macular edema. Intraocular hypertension occurred in five eyes (4.5%) (three in Group A and two in Group B). Four eyes (3.6%) underwent another surgical procedure for a persistent macular hole (two in Group A and two in Group B). The intraocular lens repositioning was performed one day after surgery in three eyes (2.7%) (Group A). The mean preoperative visual acuity was not different between the two groups (p = 0.80). CONCLUSION No significative differences between combined surgery and vitrectomy alone have been detected, in terms of postoperative complications and visual outcome.

Morpho-Functional Evaluation of Full-Thickness Macular Holes by the Integration of Optical Coherence Tomography Angiography and Microperimetry. J Clin Med 2020; 9:jcm9010229. [PMID: 31952306 PMCID: PMC7019327 DOI: 10.3390/jcm9010229] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 12/30/2019] [Accepted: 01/12/2020] [Indexed: 01/19/2023] Open
Abstract
(1) Objective: To use optical coherence tomography angiography (OCTA) and microperimetry (MP) to evaluate the correlation between retinal structure and function in patients with idiopathic, full-thickness macular holes (FTMHs) (2) Methods: This prospective, observational study included 11 eyes of 10 patients with FTMHs evaluated before surgery using OCTA and MP. MP sensitivity maps were superimposed and registered on slabs corresponding to superficial capillary plexus (SCP) and deep capillary plexus (DCP) on OCTA, and on the outer plexiform layer (OPL) and the Henle fiber layer (HFL) complex in en face OCT. On these maps, mean retinal sensitivity was calculated at 2° and 4°, all centered on the FTMH. Cystic cavity extension was assessed on the slab corresponding to the OPL + HFL complex in en face OCT and DCP in OCTA using the Image J software (Version 1.49v; National Institutes of Health, Bethesda, MD, USA); (3) Results: Absolute scotomas were observed corresponding to the FTMH. Additionally, rings of relative scotoma in the perilesional area were detected and correlated to the cystic spaces on en face OCT and OCTA. There was a significant correlation between reduced retinal sensitivity at 2° and 4° diameters around the FTMH and the extension of cystic areas (p < 0.01). There was a significant correlation between the extension of cystic cavities and BCVA (p < 0.01). (4) Conclusions: Morpho-functional analysis of FTMH using OCTA and MP, and the correlation between vascular abnormalities and impaired retinal sensitivity, may provide new, useful information. This integrated evaluation of FTMH may be useful to determine the function–structure correlation before and after vitreoretinal surgery, in order to gain a better understanding of the functional consequences induced by the morphological alterations, assessing outcomes in a more objective way, and potentially adding new surgical prognostic factors.

IOL repositioning using iris sutures: a safe and effective technique. Int J Ophthalmol 2019; 12:1972-1977. [PMID: 31850184 DOI: 10.18240/ijo.2019.12.21] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2018] [Accepted: 12/04/2018] [Indexed: 11/23/2022] Open
Abstract
This retrospective non-comparative consecutive case series study was conducted at Azienda Ospedaliera Universitaria Careggi, Florence, Italy and describes a useful intraocular lens (IOL) repositioning technique using iris sutures. In our study, 41 consecutive cases of posteriorly dislocated IOLs were surgically treated between January 2015 and May 2017. Six of the cases were post-traumatic luxations, and 20 patients had pseudoexfoliation syndrome. All the patients underwent pars plana vitrectomy and same IOL repositioning using iris sutures. The mean follow-up was 12.2mo. The mean preoperative best corrected visual acuity (BCVA) was 0.10±0.15 logMAR, whereas the mean postoperative BCVA was 0.08±0.14 logMAR. The mean postoperative BCVA did not change significantly from the preoperative BCVA. The final mean spherical equivalent was -0.44±0.49 SD. Three lenses (7.31%) were found tilted during post-operative follow-up. Two eyes (4.87%) had postoperative cystoid macular edema. No eyes had endophthalmitis, hypotony, retinal or choroidal detachment. The iris fixation technique seems to be a safe and valid option for the management of dislocated IOLs.

Abstract
Objective Intraocular lens (IOL) repositioning using a closed-eye approach could be carried out in some selected cases. Our study focuses on the efficacy and safety of a IOL closed-eye repositioning technique using scleral suture, which is performed using a trocar as an intrastromal limbal guide. Methods and analysis Thirty-one eyes of 31 patients with late IOL dislocation operated on between January 2015 and May 2017 were included in this retrospective non-comparative consecutive case series study. The patients had a single-piece in-the-bag dislocation or a 3-pieces in-the-bag or out-of-the-bag dislocation. The patients underwent an anterior vitrectomy and a scleral refixation in a closed chamber using a 10/0 polypropylene suture passed through a 25 Gauge trocar inserted in the anterior chamber. Results The mean follow-up time was 19.54 months. Average preoperative best-corrected visual acuity (BCVA) was 0.73 LogMar (±0.21 SD); while average postoperative BCVA was 0.27 LogMar (±0.23 SD). Fifteen patients underwent anterior pars plana vitrectomy (PPV) while 16 patients did not; moreover, two patients underwent PPV. Six patients had an increase of postoperative intraocular pressure, two patients had postoperative decentration, two patients had postoperative cystoid macular oedema, none of the patients had major complications such as retinal detachment, choroidal detachment, malignant glaucoma, irreversible corneal decompensation and endophthalmitis. Conclusion We can affirm that our technique may be safe and useful in the case of 3-piece in-the bag or out-of the bag dislocated IOLs and also in the case of in-the-bag single-piece dislocated IOLs.

Abstract
BACKGROUND The complement system has been implicated in the pathogenesis of age-related macular degeneration (AMD) and the CFH Y402H polymorphism has been suggested as a major risk factor for AMD. Recent evidences supported the role of inflammation in the pathogenesis of some retinal dystrophies. Aim of this study was to evaluate the prevalence of CFHY402H polymorphism in a group of Italian patients affected by atrophic AMD, Stargardt disease (STGD), or retinitis pigmentosa(RP). MATERIALS AND METHODS Our case-control association study included 116 patients with atrophic AMD, 77 with RP, 86 with STGD, and 100 healthy controls. All the patients were evaluated by a standard ophthalmologic examination and OCT. ERG was performed on STGD and RP patients. All the subjects underwent a blood drawing for genetic testing and the CFHY402H polymorphism was genotyped with the TaqMan real-time polymerase chain reaction single nucleotide polymorphism assay. RESULTS The prevalence of the risk genotype C/C was higher in the AMD group than in controls (p < 0.001). The risk allele C was more frequent in the AMD group than in controls (p < 0.001). The prevalence of the risk genotype was higher in the RP patients than in controls (p < 0.001) and similarly the risk allele C was more frequent in the RP group (p = 0.008). The CFHY402H genotype distribution was not different between patients with STGD and the controls, for the biallelic (p = 0.531) and for the monoallelic (p = 0.318) evaluation. CONCLUSIONS In our series of Italian patients, the CFHY402H genotype is associated with atrophic AMD and RP, but not with STGD. This result may support the hypothesis of a complement system dysregulation in the pathogenesis of AMD and RP.

Evaluation of ocular perforation during retrobulbar block using high-resolution spectral domain–optical coherence tomography and optical coherence tomography angiography. Eur J Ophthalmol 2018; 28:NP7-NP10.

Abstract
Introduction: This article reports a case of ocular perforation during a retrobulbar block in a patient who underwent scleral buckle for retinal detachment. Methods: Sterile air was immediately injected into the vitreous cavity to restore intraocular pressure and the scleral buckle operation was quickly finished. One week later, a laser retinopexy was performed on the two retinal holes that were outside the foveal area. After 6 months, spectral domain–optical coherence tomography and optical coherence tomography angiography were performed on the perforated wall centered on the exit hole area. Results: The visual acuity was maintained 20/20 and the retina was totally attached. Spectral domain–optical coherence tomography showed a localized interruption of inner retina, retinal pigment epithelium, and choroid, with a higher posterior reflectivity in correspondence with the sclera. Optical coherence tomography angiography was able to detect atrophic alterations in the choroidal slab with a good visualization of large and rarefied choroidal vessels due to lack of retinal pigment epithelium and choriocapillaris. Conclusion: When ocular perforation by a needle is outside the foveal area and when there is an early awareness of the perforation, the complications may be avoided, and we could observe a good final visual acuity result. Furthermore, using spectral domain–optical coherence tomography and optical coherence tomography angiography, we could observe the perforated eyeball wall and study the effects of a 25-gauge needle perforation in the retinal and choroidal blood stream.

Abstract
Purpose Choroidal thickness (CT) evaluation with EDI-OCT in Stargardt Disease (STGD), considering its possible association with some clinical features of the disease. Methods CT was evaluated in 41 STGD patients and in 70 controls. Measurements were performed in the subfoveal position and at 1000 μm nasally and temporally. CT average values in STGD and in the control group were first compared by means of Student’s T test. Then, the possible association between CT and some clinical features was evaluated by means of linear regression analysis. Considered clinical parameters were: age, age on onset, duration of the disease, visual acuity, foveal thickness, Fishman clinical phenotype, visual field loss and ERG response. Results Average CT was not significantly different between controls and STGD patients. In the STGD group the correlation between CT and age (r = 0.22, p = 0.033) and age of onset (r = 0.05, p = 0.424) was modest, while that of CT with disease duration (r = 0.30, p<0.001) was moderate. CT and foveal thickness were also significantly but modestly correlated (r = 0.15, p = 0.033). Conclusion In our series average CT is not significantly changed in STGD in comparison with the controls. Nevertheless a choroidal thinning may be identified in the more advanced stages of the disease.

Abstract
PURPOSE To evaluate the 10-year drug retention rate of infliximab (IFX) in Behçet's disease (BD)-related uveitis, the effect of a concomitant use of disease modifying anti-rheumatic drugs (DMARDs) on drug survival and differences according to the lines of biologic treatment. METHODS Cumulative survival rates were studied using the Kaplan-Meier plot, while the Log-rank (Mantel-Cox) test was used to compare survival curves. RESULTS Forty patients (70 eyes) were eligible for analysis. The drug retention rates at 12-, 24-, 60- and 120-month follow-up were 89.03%, 86.16%, 75.66% and 47.11% respectively. No differences were identified according to the use of concomitant DMARDs (p = 0.20), while a statistically significant difference was observed in relation to the different lines of IFX treatment (p = 0.014). Visual acuity improved from baseline to the last follow-up visit (p = 0.047) and a corticosteroid-sparing effect was observed (p < 0.0001). CONCLUSIONS IFX retention rate in BD-uveitis is excellent and is not affected by concomitant DMARDs.

Abstract
Background/aimsAdalimumab (ADA) has been shown to be an effective treatment for Behçet’s disease (BD)-related uveitis. We aimed at evaluating the cumulative retention rate of ADA during a 48-month follow-up period in patients with BD-related uveitis, the impact of a concomitant use of disease modifying anti-rheumatic drugs (DMARDs) on ADA retention rate, and differences according to the various lines of biologic therapy (ie, first- vs second-line or more). Predictive factors of response to ADA were also investigated.MethodsWe enrolled patients diagnosed with BD-related uveitis and treated with ADA between January 2009 and December 2016. Cumulative survival rates were studied using the Kaplan-Meier plot, while the log-rank (Mantel-Cox) test was used to compare survival curves. Statistical analysis was performed to identify differences according to the response to ADA.Results54 consecutive patients (82 eyes) were eligible for analysis. The drug retention rate at 12- and 48-month follow-up was 76.9% and 63.5%, respectively. No statistically significant differences were identified according to the use of concomitant DMARDs (p=0.27) and to the different lines of ADA treatment (p=0.37). No significant differences were found between patients continuing and discontinuing ADA in terms of age (p=0.24), age at BD onset (p=0.81), age at uveitis onset (p=0.56), overall BD duration (p=0.055), uveitis duration (p=0.46), human leucocyte antigen-B51 positivity (p=0.51), and gender (p=0.47).ConclusionsADA retention rate in BD-related uveitis is excellent and is not affected by the concomitant use of DMARDs or by the different lines of biological therapy. Negative prognostic factors for BD uveitis do not impact ADA efficacy.

Abstract
BACKGROUND AND OBJECTIVE To compare the features of cystoid cavities associated with full-thickness macular hole (FTMH) imaged with optical coherence tomography angiography (OCTA) and en face OCT. PATIENTS AND METHODS Prospective, observational, cross-sectional study. Clinical practice and observation. Thirteen patients (13 eyes) with FTMH were evaluated before vitrectomy. All eyes underwent OCTA or en face OCT imaging. RESULTS There was a statistically significant positive correlation between groups for the total cavity area in both inner nuclear layer (P < .001; r2 = 0.82) and outer plexiform and Henle fiber layer complex (P < .001; r2 = 0.84). CONCLUSIONS OCTA and en face image of cystoid cavities show very similar features and are complementary for the evaluation of the disease. The OCTA images show "vascular sliding" at the border of the cystoid cavities in FTMH, suggesting preservation of microvasculature surrounding the cystoid spaces during the disease process.

Abstract
BACKGROUND The evidence on the use of dexamethasone implants in the treatment of Behçet's disease (BD)-related uveitis is limited to a few cases. OBJECTIVES To evaluate the efficacy of dexamethasone implants on ocular functional, morphological, and clinical parameters in BD patients with severe refractory uveitis. METHODS Five eyes from five BD patients were enrolled. A single intravitreal dexamethasone injection was applied to each eye. Best corrected visual acuity (BCVA), central macular thickness (CMT) assessed with optical coherence tomography, retinal vasculitis assessed by fluorescein angiography, vitreous haze score (Nussenblatt scale), intraocular pressure (IOP), and lens status (LOCS III, Lens Opacities Classification System III) were recorded at baseline and at 1, 3, and 6 month follow-up visits. RESULTS At baseline, all eyes showed marked macular edema and 4/5 had concomitant active retinal vasculitis. Mean BCVA was increased from baseline at each control visit with a mean improvement of 0.26 ± 0.18 lines at 6 months follow-up. Mean CMT decreased from baseline at each control visit with a mean improvement at 6 months follow-up of 198.80 ± 80.08 µm. At the end of the study, none of the eyes showed macular edema and the mean CMT was 276.80 ± 24.94 µm. Retinal vasculitis resolved in all eyes. One eye experienced an IOP spike during treatment that resolved spontaneously, and one eye developed a clinically significant lens opacity at 6 months follow-up. CONCLUSIONS Treatment with a dexamethasone implant in BD-uveitis and inflammatory macular edema was safe and effective as an additional treatment combined with systemic immunomodulatory drugs.

Abstract
PURPOSE To evaluate the effectiveness and the systemic corticosteroid sparing effect of a single intravitreal dexamethasone (DEX) implant in patients with chronic noninfectious uveitic macular edema (UME). METHODS Data from 22 eyes treated with DEX implant for UME related to systemic or ocular-confined noninfectious diseases were retrospectively analyzed. RESULTS The mean systemic prednisone (or equivalent) dosage significantly decreased at 3- and 6-month follow-up evaluations compared to baseline (P = 0.002 and P = 0.01, respectively). Compared to baseline, central macular thickness values significantly decreased at 1-, 3-, and 6-month evaluations after the implantation (P < 0.0001). The mean best corrected visual acuity (BCVA) value gradually improved at 1-, 3-, and 6-month visits compared to baseline (P = 0.009, P = 0.0004, and P = 0.0001, respectively). At fluorescein angiography, active retinal vasculitis was identified in 11 (50%) eyes at baseline, 3 (13.6%) eyes at 1- and 3-month follow-up, and in 2 (9.1%) eyes at the last visit. Regarding side effects, 3/22 (13.6%) eyes presented a newly recognized intraocular hypertension at 1-month follow-up; however, intraocular pressure reverted to normal values within the 6-month follow-up in all cases. CONCLUSIONS Treatment with intravitreal DEX implant in noninfectious uveitis allowed a significant corticosteroid sparing effect, a significant improvement in BCVA, and a prompt resolution of UME and vasculitis. No safety issues were observed.

Abstract
PURPOSE To report for the first time a case report of a Stargardt disease patient who developed a macular hole (MH) which was treated with a surgical approach. METHOD Case report. RESULTS After vitrectomy a complete closure of the MH was obtained and the best-corrected visual acuity remained stable. No complications were reported after one year of follow-up. An ultra-structural examination of the removed internal limiting membrane (ILM) and epiretinal membrane (ERM) was carried out under electron microscopy. CONCLUSION Vitreo-retinal surgery could represent a therapeutic option to treat vitreo-retinal interface abnormalities associated with inherited retinal diseases.

Efficacy and safety of adalimumab in Behçet's disease-related uveitis: a multicenter retrospective observational study. Clin Rheumatol 2016; 36:183-189. [PMID: 27853889 DOI: 10.1007/s10067-016-3480-x] [Citation(s) in RCA: 62] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2016] [Revised: 11/03/2016] [Accepted: 11/06/2016] [Indexed: 01/21/2023]
Abstract
The study aim was to evaluate the efficacy of adalimumab (ADA) in a large series of Behçet's disease (BD)-related uveitis. We performed a multicenter retrospective observational study including 40 selected patients (66 eyes) receiving ADA. Clinical data were retrospectively analyzed at baseline, at 3 and 12 months of treatment. Primary end point was reduction of ocular inflammatory flares. Secondary end points were improvement of best corrected visual acuity (BCVA), reduction of macular thickness measured by optical coherence tomography (OCT), reduction in the occurrence of vasculitis assessed by fluorescein angiography (FA), and evaluation of statistically significant differences between patients treated with ADA monotherapy and those undergoing ADA plus DMARDs and in patients firstly treated with ADA compared to patients previously administered with other biologics; ADA steroid sparing effect was also evaluated. During the first 12 months of ADA therapy, the number of flares significantly decreased from 200 flares/100 patients/year to 8.5 flares/100 patients/year (p < 0.0001). Similarly, BCVA improved if compared to baseline (7.4 ± 2.9 versus 8.5 ± 2.1, p = 0.03). OCT findings significantly improved showing a mean reduction of central macular thickness (CMT) of 27.27 ± 42.8 μm at the end of follow-up (p < 0.006). FA identified retinal vasculitis in 22 cases at baseline (55%), 8 (20%) cases after 3 months, and in only one (2.5%) case at 12-month follow-up. FA improvement was highly significant at 3- and 12-month follow-up if compared to baseline (p < 0.0001 and p = 0.006, respectively). ADA is highly effective and safe for the treatment of BD-related uveitis, providing a long-term control of ocular inflammation.
