RESUMO
Background Retinal vasculitis is an inflammatory condition that affects the retinal blood vessels. Summary It can manifest as an idiopathic disorder or be secondary to various infectious or non-infectious diseases, mimicking syndromes, isolated ocular disorders, or drug-induced reactions. Recognizing its distinctive features is crucial for early diagnosis and accurate treatment. This review aims to demonstrate the variety of tools available to detect disease activity, assess complications, measure the extent of retinal damage, and guide therapy effectively. Key Message This review article highlights the use of multimodal imaging in the comprehensive evaluation of retinal vasculitis.
RESUMO
BACKGROUND: Retinal vasculitis (RV) signifies the inflammation of various retinal vessels. Noninfectious RV differs from infectious RV with regard to its pathogenesis and treatment. It can have varied clinical presentations and may be associated with systemic vasculitic diseases. SUMMARY: Noninfectious RV can be caused due to type-III hypersensitivity reactions, increased expression of intracellular adhesion molecules, and genetic susceptibility. Noninfectious RV is primarily classified on the basis of the type of retinal vessels involved. It can be further classified as an occlusive or nonocclusive. RV can be a major association of systemic diseases like Behcet's disease, sarcoidosis and systemic lupus erythematosus. Newer modalities, like ultra-widefield fundus fluorescein angiography, can help in the management of RV. Effective treatment of noninfectious RV requires anti-inflammatory and immunosuppressive therapy. The patients may require treatment with high-dose corticosteroids and biological agents. Anti-vascular endothelial growth factor injections and laser photocoagulation may be indicated to treat the occlusive disease. Prompt treatment may prevent complications like vitreous hemorrhage, neovascular glaucoma, and tractional retinal detachment. The treatment more often requires a multidisciplinary approach. KEY MESSAGES: This review provides a comprehensive update on the various causes of noninfectious RV, including both systemic and isolated ocular conditions. It also details various complications and management strategies for this condition.
RESUMO
PURPOSE: To assess the effectiveness of a switch to faricimab in individuals affected by DME and previously treated with aflibercept. METHODS: In this retrospective, single-center study, DME patients previously treated with at least 3 injections of aflibercept then switched to faricimab were enrolled. Best corrected visual acuity (BCVA) and central subfield thickness (CST) were recorded at baseline, at the time of the switch and at 6 months follow-up. At transition to faricimab, patients were categorized as "good visual responders" (≥ 5 letters from baseline) or "poor visual responders" (< 5 letters), and as "good anatomical responders" (any reduction in edema compared to baseline) or "poor anatomical responders" (no reduction or worsening of edema). Changes in BCVA and CST were recorded at 6 months after the switch to faricimab. RESULTS: 100 eyes of 100 patients (61 female, 61%) were switched to faricimab after a mean of 6.8 ± 3.3 aflibercept injections. At the 6 months follow-up, only "poor visual responders" (N = 62) demonstrated a meaningful increase in BCVA (Δswitch-6M = + 5 letters; P = 0.007), coupled with a reduction in CST (Δswitch-6M = - 67.9 µm; P = 0.004); participants with "poor anatomical response" upon transitioning exhibited a significant functional gain (Δswitch-6M = + 4.5 letters; p = 0.05) but limited CST enhancements (Δswitch-6M = - 95.1 µm; p = 0.05). CONCLUSIONS: Faricimab shows a positive impact on anatomical and functional metrics in DME cases refractory to aflibercept.

As optical coherence tomography angiography is revolutionizing the ophthalmology world, the uveitis community is learning to understand where and how this new powerful imaging tool fits into the management of the panorama of ocular inflammations and infections. A non-invasive method of studying the retinal and choroidal vasculature, OCTA allows for the assessment of vessel density changes during active and inactive uveitis making it the natural imaging application of choice in uveitis clinical trials. However, these data and results are of limited utility to the ophthalmologists who are looking to apply OCTA in their everyday uveitis clinic. If employed strategically, OCTA can be a powerful tool for the uveitis specialist to evaluate iris involvement in viral uveitis; to assess the integrity of the vascular layers in the settings of white dot syndromes; to distinguish inflammatory choroidal neovascularization from outer retinal avascular inflammatory material; and to diagnose and follow infectious choroidal granulomas and satellite foci of chorioretinal inflammation without the need to administer dyes. The present review will analyze all the recent publications that apply OCTA in uveitis to offer the reader a guide on how to maximize the utility of this imaging modality in a clinical practice.

PURPOSE: To describe the clinical and multimodal imaging features of stellate multiform amelanotic choroidopathy (SMACH; also known as serous maculopathy due to aspecific choroidopathy). METHODS: Retrospective observational case series of eyes presenting with SMACH. Multimodal imaging including fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), and indocyanine green angiography (ICGA) was analyzed. RESULTS: Eighteen eyes from 18 patients (mean age: 28 ± 19 years) were included. The mean follow-up duration was 9 years. Ophthalmoscopy showed a yellowish orange, dendriform choroidal lesion. At presentation, subretinal fluid (SRF) was seen in 10 of 18 cases (56%). Eight patients (44%) showed no evidence of SRF during a mean follow-up of 6 years. Cross-sectional OCT showed hyperreflective fibrous-like changes within the inner choroid with choriocapillaris flow preservation on OCTA. En face OCT showed a hyperreflective choroidal lesion with finger-like projections oriented in a stellate configuration. On ICGA, SMACH showed early and late hypofluorescence. None of the cases showed lesion growth. CONCLUSION: SMACH seems to be a unilateral choroidopathy characterized by distinctive multimodal imaging features. As SRF was absent in some cases, while a dendriform pattern was a consistent finding in all eyes, the authors propose renaming this entity "stellate multiform amelanotic choroidopathy," a name that retains its previous abbreviation "SMACH."

BACKGROUND: Evaluation of ocular inflammation via common imaging modalities like optical coherence tomography (OCT) has emphasised cell visualisation, but automated detection of uveitic keratic precipitates (KPs) remains unexplored. METHODS: Anterior segment (AS)-OCT dense volumes of the corneas of patients with uveitic KPs were collected at three timepoints: with active (T0), clinically improving (T1), and resolved (T2) inflammation. At each visit, visual acuity and clinical grading of the anterior chamber cells were assessed. A bespoke algorithm was used to create an en face rendering of the KPs and to calculate their volume and a ratio of the volume of precipitates over the analysed area. The variation of AS-OCT-derived measurements over time was assessed, and compared with clinical grading. RESULTS: Twenty eyes from 20 patients (13 females, mean age 39 years) were studied. At T0, the mean volume of the corneal KPs was 0.1727 mm3 , and it significantly reduced to 0.1111 mm3 (p = 0.03) only at T2. The ratio between the volume of the KPs and the corneal area decreased from T0 (0.007) to T1 (0.006; p = 0.2) and T2 (0.004; p = 0.009). There was a statistically significant correlation between the AC cell count and the AS-OCT volume measurements of the KPs at the three time points. CONCLUSIONS: AS-OCT can image uveitic KPs and through a bespoke algorithm we were able to create an en face rendering allowing us to extrapolate their volume. We found that objective quantification of KPs correlated with inflammatory cell counts in the anterior chamber.

BACKGROUND: To demonstrate the safety and efficacy of the intracameral use of tropicamide 0.02%/phenylephrine 0.31%/lidocaine 1% in pediatric cataract surgery, a combination widely used in adult patients but still off-label in children. METHODS: Design: two-center, prospective, observational study. SETTING: San Giuseppe Hospital, Milan and Meyer Children's Hospital, Florence. STUDY POPULATION: children from 0 to 4 years of age undergoing cataract surgery with or without intraocular IOL implantation, in the absence of clinically significant systemic conditions, history of ocular surgery, concurrent ocular medication, hypersensitivity to any of the substances and post-traumatic cataracts. During the surgery, patients received the combination drug after the primary access to the anterior chamber. Efficacy was evaluated by achieving an adequate mydriasis in order to perform capsulorhexis, while safety was assessed by recording vital signs (heart rate, blood pressure, respiratory rate, temperature) pre- and post-administration of the substance. RESULTS: This study included 53 surgical procedures of 36 patients: 41 eyes were left aphakic, while 12 eyes received primary IOL implantation. The pupil size was adequate to safely perform capsulorhexis in 52 procedures of 53. The difference in pupil enlargement was significant (6.0 ± 1.14 mm, P = < 0.001). There were no notable changes in vital parameters. CONCLUSIONS: The administration of intracameral tropicamide 0.02%/phenylephrine 0.31%/lidocaine 1% in pediatric cataract surgery is effective for obtaining an adequate mydriasis without any vital parameters changes throughout the procedure.

PURPOSE: To investigate choroidal granulomas visualized by indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCTA) in response to treatment. METHODS: Ten eyes of eight patients with tubercular, sarcoid, or Vogt-Koyanagi-Harada-associated choroidal granulomas were evaluated in this multicentric study. All patients underwent ICGA and OCTA at baseline, 1, and 3 months after treatment onset. Granulomas were identified as hypofluorescent lesions on intermediate ICGA phases. Late ICGA behavior and OCTA visualization were assessed. RESULTS: On baseline intermediate ICGA, 222 choroidal granulomas were detected. Overall, 174/222 granulomas were detected on baseline OCTA images. At 1 month, 28% of lesions were healed and 48 late ICGA hyperfluorescent lesions were identified. At 3 months, 63% of baseline lesions were healed, with 33 persistent late hyperfluorescent lesions. Optical coherence tomography angiography sensitivity was reduced at 1 and 3 months compared with baseline. Some flow-voids detected on OCTA at 1 and 3 months did not correspond to any visible lesion on ICGA. CONCLUSION: Different healing behaviors of choroidal granulomas were identified combining ICGA and OCTA analysis. Late ICGA hyper-fluorescent lesions may be the consequence of a possible fibrotic shift. Structural changes in the choroid may persist after active granulomas resolution resulting in persistent flow voids on OCTA.

PURPOSE: To assess the visualization of choroidal granulomas with swept-source optical coherence tomography angiography (OCTA). METHODS: Consecutive patients with granulomatous choroiditis due to tuberculosis, sarcoidosis, or Vogt-Koyanagi-Harada disease underwent baseline OCTA images using a 12 × 12-mm field of view, and the choroidal slabs were analyzed by two independent examiners who counted the oval areas of flow void. Simultaneously, indocyanine green angiography (ICGA) and enhanced-depth imaging OCT were performed to mark visible choroidal changes corresponding to granulomatous lesions. The lesion areas on OCTA and ICGA were assessed using the in-built caliper tool. RESULTS: Three hundred and one round-shaped areas of flow void on OCTA, 209 hypofluorescent round lesions on ICGA, and 42 hyporeflective choroidal lesions on enhanced-depth imaging OCT were identified in 23 eyes from 14 patients. Of the 209 ICGA granulomas, 197 (94.3%) had a corresponding round area of flow void on OCTA that was interpreted as a granuloma. One hundred and four additional round flow voids were identified on OCTA that did not correspond to any hypofluorescent lesion on ICGA. The mean area of the 197 granulomas detected with both imaging modalities was significantly larger on ICGA (mean 0.33 mm2) than that on OCTA (mean 0.28 mm2). CONCLUSION: Optical coherence tomography angiography seems to be an optimal imaging method for the visualization of choroidal granulomas.

PURPOSE: To compare the ability of wide-field optical coherence tomography angiography (WF-OCTA) to that of ultra-wide field fluorescein angiography (UWF-FA) and ultra-wide-field color fundus photography (UWF-CP) to detect retinal neovascularization (NV) in eyes with proliferative diabetic retinopathy (PDR). METHODS: In this cross-sectional study, naïve patients with active PDR underwent UWF-FA and UWF-CP using the Optos 200Tx and WF-OCTA with 12 × 12 mm fields of five visual fixations using the PLEX Elite 9000. NV was defined on OCTA when the co-registered B-scan with flow overlay of the vitreoretinal interface (VRI) segmentation showed extraretinal proliferation. Three masked readers examined the UWF-FA, UWF-CP, and WF-OCTA independently for the presence of NV. Statistical analysis was performed to compare the diagnostic accuracy of the 3 wide-field imaging modalities using OCT B-scan as the reference standard. RESULTS: In 82 eyes with PDR, neovascularization of the disc (NVD) was detected in 13 eyes by UWF-CP, 35 eyes with UWF-FA, and 37 eyes with OCTA using the VRI slab. Upon review of the 2500 OCT B-scans with superimposed flow overlay of each eye, NVD was confirmed in 37 eyes. The sensitivity and specificity of NVD detection were 35.1% and 97.8%, respectively for UWF-CP; 94.6% and 100%, respectively, for UWF-FA; and 100% and 100% for WF-OCTA. One hundred ninety-six foci of neovascularization elsewhere (NVE) were identified with the OCT B-scan with superimposed flow overlay. UWF-CP analysis was able to detect 62 foci of NVE of the 196 confirmed by B-scan (31.6% detection rate). An additional 11 foci of NVE seen on UWF-CP were not confirmed by B-Scan (15% false positive rate). There were 182 foci of NVE identified by UWF-FA (detection rate 91.3%), while WF-OCTA detected 196 retinal NVEs (detection rate 100%). The rate of false positives for both UWF-FA and WF-OCTA was low (< 2%). CONCLUSION: WF-OCTA can identify NV that is not evident in UWF-CP and represents a faster and safer alternative to UWF-FA for surveillance of PDR with comparable diagnostic accuracy.

PURPOSE: To describe patients with intermediate uveitis complicated by vasoproliferative tumors (VPTs). METHODS: Data were collected at seven Uveitis/Ocular Oncology centers on demographic, ophthalmic findings at baseline and at follow-up, and on imaging. The therapeutic intervention, final visual acuity, and duration of follow-up were recorded. RESULTS: A total of 36 eyes from 34 patients (12 men, 22 women; mean age 35.3 ± 14.2 years) were included in this study. Visual acuity at presentation ranged from 20/40 to counting fingers. At the time of VPT diagnosis, intermediate uveitis was active in all eyes. The mean VPT thickness was 3.06 ± 0.86 mm. Local treatment to the VPT was provide in 22 eyes (61.1%) and no local treatment to the VPT in 14 eyes (38.9%). After the VPT was detected, systemic or local treatment for the inflammation was initiated and on follow-up FAs 94.4% of the eyes showed resolution of the vascular leakage. During follow-up of 35.8 months, the 22 VPTs treated locally had a reduction in the tumor thickness to 1.25 mm, whereas the 14 VPTs untreated remained stable (final mean tumor thickness 2.65 mm). CONCLUSION: The presence of active intermediate uveitis accompanied by VPTs suggests the need for an aggressive uveitis treatment.

PURPOSE: To review the multimodal imaging patterns of posterior syphilitic uveitis. METHODS: A systematic review. RESULTS: The percentage of syphilis has started to increase again: The World Health Organization has reported 12 million new cases of syphilis each year. In addition, syphilis was responsible for 0.3% of deaths globally in 2002. Eye manifestations happen prevalently in secondary and tertiary stages of syphilis, even though ocular involvement can occur in all stages. Syphilis has the nickname: "the great imitator" since it has no unique clinical presentation, even though posterior uveitis is considered the most common form. Syphilis is known as "the great imitator," making its diagnosis in the presence of posterior uveitis particularly challenging as it presents similarly to other ocular conditions such as acute retinal necrosis. However, with the advent of multimodal imaging some particular patterns of pre-retinal, retinal, retinochoroidal and optic nerve involvement from syphilis can be identified to guide the diagnosis and the laboratory workup. CONCLUSION: This review highlights the various patterns of pre-retinal precipitates, multifocal retinitis, retinochoroiditis (confluent and placoid) and optic neuritis caused by syphilis, the appropriate laboratory work to be obtained and the treatment to be initiated.

PURPOSE: Cases of sudden loss of central vision in eyes with silicone oil in situ and after oil removal have been described. The aim of this review is to present current data on silicone oil toxicity to the neuronal aspects of the retina as well as the Cleveland Clinic Abu Dhabi experience with this retinopathy (maculopathy). METHODS: A PubMed review using the terms "silicon oil" and/or "toxicity" and/or "ganglion cell" and/or "nerve fiber" was conducted to identify case reports, case series, and original articles presenting toxicity from silicon oil. Timing of visual loss, as well as SD-OCT data and RNFL/GCC analysis, was collected. Selected cases were pooled from Cleveland Clinic Abu Dhabi Vitreoretinal database to further reinforce the findings. RESULTS: Twenty-four papers were identified (case/series/articles). The earliest papers that met our criteria seemed to report vision loss at the time of or after silicone oil removal; however, more recent studies have described such toxicity from 1 to 6 months after tamponade with silicone oil in situ. Since the first description of central visual loss from silicone oil, all researchers describe a thinning of perifoveal ganglion cells measured with SD-OCT, while there is no concordance as far as RNFL changes, with some authors describing a thinning and others a thickening, but neither was ever clearly associated with visual loss. The correlation between SD-OCT hyperreflective goblets in the inner retina and histological description of intraretinal oil droplets migration seems to suggest instances of silicone oil penetration in the retinal layers. CONCLUSION: In a small percentage of cases who underwent retinal tamponade with silicone oil, ganglion cells can suffer a direct damage either from particles of oil that migrate in the retina or from direct contact with it. Indirect damage may be caused by phototoxicity due to the transparent nature of silicon oil or by inflammatory damage from cytokines sandwiched between oil and retina.

PURPOSE: Retinal manifestations are present in 10% of patients with systemic lupus erythematosus (SLE) and consist of vascular changes that can be sight-threatening. Optical coherence tomography angiography (OCTA) is a novel imaging modality that detects movement inside the blood vessels without dye injection and transforms this movement into an angiographic map. The aim of this study is to describe subclinical vessels changes in the eyes of patients with SLE but no retinal manifestations. METHODS: In this cross-sectional study, 15 patients with SLE but no clinical ophthalmic manifestations were scanned through OCTA of the iris and at the level of the macula. Qualitative aspects of the iris vessels, and measure of the foveal avascular zone (FAZ) and vessel density were compared to a cohort of 15 normal controls. RESULTS: Patients with SLE, even in the absence of ophthalmic manifestations, present a qualitative increase in the iris vessels flow, and enlargement of the FAZ (0.22 ± 0.12 mm2) and a decrease in the vascular density (11.221 ± 1.933 mm-1) of the superficial capillary plexus on OCTA that cannot be highlighted clinically. DISCUSSION: OCTA can be used in a noninvasive way to detect subclinical vascular changes in patients with SLE. How this information will influence the follow-up and management of these cases will require further prospective studies with a collaborative effort between ophthalmologists and rheumatologists.

PURPOSE: To describe disorders that can masquerade as multiple evanescent white dot syndrome (MEWDS). DESIGN: Retrospective, multicenter case series. PARTICIPANTS: Patients who presented with clinical findings compatible with a diagnosis of MEWDS but were ultimately diagnosed with an alternative inflammatory, infectious, or neoplastic disorder. METHODS: Clinical records and multimodal imaging findings including fundus photography, fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA), optical coherence tomography (OCT), and OCT angiography (OCTA) were analyzed. MAIN OUTCOME MEASURES: Inclusion criteria to be defined as a masquerade syndrome for MEWDS included the presence of disseminated grayish-white outer retinal spots that were hyperautofluorescent on FAF and associated with ellipsoid zone (EZ) disruption on OCT. RESULTS: Twenty-two eyes of 13 patients were identified. All patients presented with the classic findings of MEWDS listed above. A MEWDS-like presentation was bilateral in nine of 13 patients (69%). Final diagnosis was determined on the basis of additional investigations including serologies and biopsy. These diagnoses included syphilis (three patients), lymphoma (three patients), idiopathic multifocal choroiditis (two patients), idiopathic retinal phlebitis (one patient), idiopathic acute zonal occult outer retinopathy (one patient), sarcoidosis (one patient), tuberculosis (one patient), and cancer-associated retinopathy (one patient). The outer retinal lesions and imaging findings resolved with treatment for the associated systemic disorders. CONCLUSIONS: Widespread grayish-white outer retinal spots associated with hyperautofluorescence on FAF and disruption of the EZ on OCT are not pathognomonic for MEWDS. A high index of suspicion must be maintained for masqueraders of MEWDS, which can include serious inflammatory, infectious, and neoplastic disorders.

Transsynaptic retrograde degeneration (TSRD) of the visual pathways is the loss of retinal ganglion cells occurring upstream from a posterior visual pathway lesion. We present a case of a 54-year-old woman with an epidermoid cyst at the right temporo-occipital junction, in whom retinal optical coherence tomography angiography showed a reduction of the superficial retinal capillary density consistent with TSRD. While this reduction has been described in chronic optic neuropathies and pregeniculate lesions, to our knowledge, this is the first case report showing how a reduction in the superficial retinal capillary density occurs also for a postgeniculate lesion.
RESUMO
PURPOSE: Editorial to De Giacinto et al case report on free autologous neurosensory retina patch. METHODS: Literature review and experts' opinion RESULTS: In the present issue, De Giacinto et al describe a free autologous neurosensory retina patch to close a chronic macular hole. This new technique was made necessary by an extended internal limiting membrane peeling during the first surgery, that prevented grafting a patch of internal limiting membrane when the hole did not close. We hereby review pros and cons of patching a chronic macular hole with an internal limiting membrane patch, as well as the importance of not over-enlarging a peeling. DISCUSSION: Internal limiting membrane patch can be considered in chronic macular holes. It may not be an option in cases of over-enlargement of a previous peel; free autologous neurosensory retina patch may be a valid alternative in such cases.

PURPOSE: To compare the efficacy of a modified PRN treatment regimen ("treat and monitor") of aflibercept and ranibizumab in macular edema secondary to non-ischemic branch retinal vein occlusion. METHODS: Seventy eyes of 70 patients with treatment naïve branch retinal vein occlusion were enrolled. All patients underwent a comprehensive ophthalmic examination, spectral-domain optical coherence tomography, and fluorescein angiography. Patients were randomized 1:1 to receive intravitreal aflibercept (34 eyes) and ranibizumab (36 eyes) with a "treat and monitor" treatment regimen with monthly follow-up for 12 months. Primary outcome measures included mean change in best corrected visual acuity (BCVA) and central foveal thickness (CFT) at month 12 compared to baseline. RESULTS: At 12 months follow-up, the mean BCVA improved from 0.58 ± 0.13 to 0.20 ± 0.15 logMAR (P = 0.0003) in the aflibercept group (mean injections 2.6 ± 1.51) and from 0.52 ± 0.11 to 0.21 ± 0.1 logMAR (P = 0.0002) in the ranibizumab group (mean injections 2.8 ± 1.78). No statistical difference between the two groups in terms of the visual acuity gains in eyes with macular edema secondary to non-ischemic BRVO treated with either aflibercept or ranibizumab was observed. Mean CFT reduced from 498 ± 46 to 204 ± 23 µm (P < 0.0001) in the aflibercept group and from 488 ± 31 to 212 ± 29 µm (P < 0.0001) in the ranibizumab group. CONCLUSION: "Treat and monitor" regimen is a real-life effective strategy in improving visual acuity after macular edema from branch vein occlusion and in reducing the number of injections.
