Management of Perifoveal Exudative Vascular Anomalous Complex.

PURPOSE: To report a case of a patient with perifoveal exudative vascular anomalous complex (PEVAC) and to analyze morphological and vascular changes by OCT and OCTA before and after treatment. MATERIALS AND METHODS: In this case we reported a case which received multiple treatment for unresponsive effect to Repeated Aflibercept intravitreal injections, subthreshold micropulse laser therapy (SMPL) duty cycle 5%. At last the focal fully dose yellow laser was performed. RESULTS: A 57-year-old male patient presented with best corrected visual acuity (BCVA) of 20/50 in his right eye (RE) The fundoscopic evaluation, structural optical coherence tomography (OCT) and OCT angiography (OCTA) deposed for a diagnosis of PEVAC. The patient underwent three Aflibercept intravitreal injections in the RE. Since no changes were detected, we opted for multiple sessions of yellow subthreshold micropulse laser therapy (SMPL) duty cycle 5%, however no signs of regression were registered. Only after a fully dose yellow laser, signs of edema regression were observed. Stuctural OCT B-scan showed complete restitutio of retinal profile, in absence of any intraretinal or subretinal fluid and PEVAC lesion, while the OCTA showed a slight flow deficit at the previous lesion site. CONCLUSIONS: and Importance: The PEVAC treatment is still unknown. In our experience, we reported a case of multiple treatments for unresponsive effect to: Aflibercept intravitreal injections, subthreshold micropulse laser therapy (SMPL) duty cycle 5%. At list the focal fully dose yellow laser was the only effective in our patient. We proposed our management to share the heterogeneous response at PEVAC entity.

Safety Results for Geographic Atrophy Associated with Age-Related Macular Degeneration Using Subretinal Cord Blood Platelet-Rich Plasma.

Purpose: To evaluate the safety of subretinal injection of cord blood platelet-rich plasma (CB-PRP) and its possible effect in eyes affected by geographic atrophy (GA) associated with dry age-related macular degeneration (d-AMD). Design: Interventional, open-label study started in January 2021 with follow-up at 12 months (the Si.Cord Study). This study was a single-center, nonrandomized, sequential-assigned clinical trial conducted in Rome, Italy, at Fondazione Policlinico Universitario Agostino Gemelli IRCCS (ClinicalTrials.gov NCT04636853). Participants: Thirteen patients (26 eyes) with bilateral d-AMD-related GA were enrolled. One eye from each patient (with more advanced GA) underwent CB-PRP treatment, and the fellow eye was considered the control. All patients participated in follow-up at 12 months. Intervention: All 13 eyes received 23-gauge (G) vitrectomy and subretinal injection of CB-PRP using a 41-gauge needle. Main Outcomes and Measures: Best-corrected visual acuity (BCVA) with ETDRS letters, central macular thickness using OCT, and atrophic area measured on en face OCT images were assessed at baseline, 1, 3, 6, and 12 months. Results: The BCVA in the treated group was 34.46 ± 20.8 ETDRS at baseline, 40.84 ± 20.52 at 1 month, 40.07 ± 20.34 at 3 months, 39.38 ± 19.84 at 6 months, and 35.84 ± 18.38 at 12 months. In the untreated group, the BCVA was 53 ± 21.1 ETDRS letters at baseline, 51.54 ± 20.99 at 1 month, 46.62 ± 19.47 at 3 months, 46.85 ± 18.58 at 6 months, and 43.92 ± 17.97 at 12 months (2-way analysis of variance: interaction of treatment by eye or time, P = 0.084). Central macular thickness did not show a significant intereye difference at 12 months (P = 0.97). The atrophic geographic areas tended to increase in both treated and fellow eyes at 12 months (P < 0.0001). No inflammatory reaction, endophthalmitis, retinal detachment, uveitis, or other complications due to the subretinal injection of CB-PRP were observed during the follow-up. Conclusions: Subretinal injection of CB-PRP could be safely used for d-AMD in its GA form. Despite its safety, a larger cohort of patients, and probably a new way of administration, will be needed to understand whether the CB-PRP could have a role in the GA treatment.

Long Term Follow Up of a Family with A3243G Mitochondrial Syndrome.

PURPOSE: To describe the clinical and multimodal imaging (MMI) features of a family (proband, sister and mother) with A3243G mitochondrial retinopathy and long-term follow up. METHODS: Medical and imaging records were retrospectively evaluated. Multimodal imaging included ultra-widefield color fundus photography, fundus autofluorescence, and spectral-domain optical coherence tomography. Long-term MMI follow up ranged from 6 to 15 years and was available for each member. RESULTS: The proband (Case 1) exhibited rapidly progressive bilateral macular atrophy, corneal endothelial polymegathism, and an A3243G mutation in the mitochondrial DNA. The proband also endorsed a history of early-onset myocardial infarction (MI) ten years prior at the age of 42. The proband's sister (Case 2) only exhibited unilateral focal macular atrophy but admitted to a history of severe multiorgan systemic disease, including multiple sclerosis and major depression disorder. The proband's mother (Case 3), the only one with diabetes mellitus and hearing loss, originally presented with branch retinal vein occlusion in the right eye and pattern dystrophy in the left eye which evolved to geographic atrophy, OD > OS, 15 years later. CONCLUSION: A3243G mitochondrial syndrome can exhibit heterogenous ocular and systemic features, even within members of the same family. The development of the characteristic maculopathy with early-onset MI warrants genetic testing. Early cardiac and systemic screening may be recommended in individuals with characteristic retinal findings and genetic confirmation.

Retinal Pigment Epithelium and Outer Retinal Atrophy (RORA) in Retinitis Pigmentosa: Functional, Structural, and Genetic Evaluation.

Purpose: To examine whether the extension of retinal pigment epithelium (RPE) and outer retinal atrophy (RORA) and various other morphofunctional parameters correlate with the genetic assessment and severity of retinitis pigmentosa (RP). Methods: Thirty-eight patients (76 eyes) with RP were prospectively enrolled and underwent full ophthalmic examination, including visual field testing, full-field electroretinography (ERG), and optical coherence tomography angiography. The severity of the disease was calculated using the RP stage scoring system, and the area of RORA was assessed using the automatically calculated area of sub-RPE illumination. Blood or saliva samples were collected from subjects, and DNA extraction was performed to evaluate genetic mutations and nucleotide and amino acid variations. Results: There was a statistically significant correlation between the extent of RORA and patient age, best-corrected visual acuity, ellipsoid zone extension, and disease severity in both eyes (each, P < 0.05). In contrast, RORA did not correlate with either the visual field or the ERG amplitude. Cumulative score and grade severity were both significantly correlated with superficial and deep capillary plexus density (both, P < 0.001) in both eyes. Evaluating RORA, we found genes with an overall less severe phenotype, such as EYS, PCDH15, and PRPF31, and those with a worse phenotype, such as RPGR. Conclusions: The correlation of RORA with structural, functional, and genetic assessment in RP disease leads us to consider RORA as a potential biomarker for prediction of disease stage. Multicenter studies are needed to confirm our findings. Translational Relevance: The morphofunctional and genetic correlations suggest a role for RORA in RP diagnosis and follow-up.

Optical Coherence Tomography Advanced Parameters in Patients With Multiple Sclerosis: Ophthalmological and Neurological Assessments.

PURPOSE: To evaluate ophthalmological, neurological, radiological, and laboratory data in patients with multiple sclerosis (MS) and to identify new ophthalmological factors that could be helpful as biomarkers of the disease, potentially leading to an earlier prediction of disease course and disability progression. DESIGN: Retrospective, cross-sectional-study. METHODS: Best-corrected visual acuity (BCVA), ophthalmological biomicroscopy of the anterior segment and fundus, structural optical coherence tomography (OCT) with retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC), and OCT angiography (OCTA) with vascular density (VD) were performed. The following clinical and neuro-radiological features were assessed: MS phenotype, disease duration, clinical severity, type of treatment, and T2-weighted lesion and T1-weighted Gd+ enhancing lesion number on the brain and spinal cord MRI. RESULTS: One hundred and six patients (212 eyes) were analyzed. Sixty-six of them (62.2%) had MS and 40 (37.8%) were matched healthy controls (HCs). patients with MS showed lower RNFL, GCC, and VD in the radial peripapillary capillary plexus than controls in both eyes (P < .05). By Performing a logistic regression with a distinct MS outcome for both eyes, we were able to demonstrate that the value that was most predictive of MS was the average GCC thickness (P = .009). Regression analysis demonstrated that patients with a higher T2-weighted lesions showed a lower RNFL thickness value and reduced GCC and VD values than those with a low lesion load (P < .01 and P < .05, respectively). Similarly, relapsing MS patients showed lower RNFL values (P < .05). CONCLUSIONS: Several OCT and OCTA-optic nerve parameters could be useful prognostic biomarkers for the MS disease course in clinical practice. However, it is necessary to do additional research with larger sample sizes in order to validate these findings.

Pathogenesis of Central Serous Chorioretinopathy and the Link Between Choroidal Hyperpermeability and Retinal Pigment Epithelium Pump Reversal.

PURPOSE: To describe 6 cases of acute central serous chorioretinopathy (CSCR) and the response to laser treatment, focusing on the underlying pathogenic mechanism. METHODS: Multimodal imaging from 6 eyes of 6 patients with acute and recurrent CSCR were reviewed, including fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT) at baseline and after laser therapy. RESULTS: In 3 of the 6 cases with acute CSCR, the hyporeflective lucency sign was identified with cross-sectional and en face OCT and co-localized with an intense active inkblot retinal pigment epithelium (RPE) leak on FA. The development of this sign was suggestive of active leakage into the subretinal space displacing overlying subretinal hyperreflective material (SHRM) and suggestive of a reversal of RPE pump function. All 6 cases were treated with focal laser to directly target the intense leakage points with remarkable resolution of the fluid due to destruction of the RPE cells mediating reversal of pump function. CONCLUSIONS: Unlike chronic CSCR in which degenerative changes of the RPE lead to oozing of fluid into the subretinal space, in acute forms of CSCR including bullous CSCR, there are focal leaks of the RPE that actively drive fluid into the subretinal space suggestive of RPE pump reversal. We propose that pachychoroid disease causes increased hydrostatic pressure and increased resistance to the RPE pump, thereby triggering a reversal in pump function. Understanding this concept can have therapeutic implications.

OCT analysis of preoperative foveal microstructure in recent-onset macula-off rhegmatogenous retinal detachment: visual acuity prognostic factors.

BACKGROUND: To evaluate, in patients undergoing macula-off rhegmatogenous retinal detachment surgery (RRD), the correlation between preoperative optical coherence tomography (OCT) morphological features and postoperative visual acuity. METHODS: Retrospective interventional non-randomised clinical trial on 89 eyes of 89 patients undergoing pars plana vitrectomy for macula-off primary RRD at Policlinico Universitario Agostino Gemelli from 2020 to 2023. Preoperative 6×6 mm OCT B scans with Nidek Mirante (Nidek, Gamagori, Japan) were performed, collecting the following features: foveal involvement (fovea-on vs fovea-off), subretinal hyper-reflective points (HRPs), outer retinal corrugations (ORCs) and intraretinal cystic spaces (ICS) in the outer nuclear layer. The patients were followed in a 6-month follow-up to evaluate best-corrected visual acuity (BCVA) outcomes. RESULTS: Preoperative mean BCVA was 0.15±0.22 and improved to 0.29±0.3 decimals at 6 months (p<0.001). The presence of subretinal HRPs showed a significant negative impact on BCVA improvement in the univariate regression analysis (r=-0.264, p=0.024), as well as the presence of foveal detachment (r=-0.355, p=0.012). The other OCT features did not show a significant correlation with BCVA improvement: ORCs (r=0.072, p=0.257) and ICS (r=-0.020, p=0.734). In the multivariate regression analysis, the negative impact of foveal detachment was confirmed (r=-0.199, p=0.05) while the statistical significance of subretinal HRPs was lost (r=-0.135, p=0.105). CONCLUSIONS: The negative impact of foveal involvement in a macula-off RRD was confirmed. Moreover, the presence of subretinal HRPs, as a possible indirect marker of inflammatory response extent, may act as a negative predictor for postoperative visual recover. TRIAL REGISTRATION NUMBER: NCT05747144.

Infantile nystagmus syndrome: An observational, retrospective, multicenter study.

SIGNIFICANCE: This multicenter study assessed clinical and psychological aspects of infantile nystagmus syndrome (INS) focusing on its management and nonsurgical treatment. PURPOSE: This study aimed to assess clinical features, management, relationship life, and psychological impact in a group of patients with nystagmus onset in pediatric age. METHODS: This observational study included patients diagnosed with INS referred to two Italian centers from January 1, 2017, to December 31, 2020. Ophthalmologic and orthoptic features and impact of visual function on quality of life, according to nystagmus-specific nystagmus quality of life questionnaire, were analyzed within the overall sample and in any of INS subgroups. RESULTS: Forty-three patients were included; 65.1% of them had idiopathic INS (IINS), and 34.9% had INS associated with ocular diseases (INSOD). The median age was 15.4 years (interquartile range [IQR], 10.4 to 17.3 years), significantly different between groups (median, 15.8 years among those with IINS vs. 12.3 years among those with INSOD; p<0.001). In the INSOD subgroup, strabismus was significantly more prevalent (93.3 vs. 57.1%; p=0.017). Binocular distance best-corrected visual acuity in primary position was significantly higher in the IINS subsample (p<0.001). Such behavior was further confirmed at anomalous head position evaluation (p<0.001). At near best-corrected visual acuity assessment, differences between groups were more remarkable in primary position (p<0.001) than in anomalous head position. Contrast sensitivity showed significantly higher values in the IINS subgroup (p<0.001). The nystagmus quality of life questionnaire disclosed a significantly lower score in IINS as compared with INSOD (median total score, 90.5 [IQR, 84 to 97] vs. 94 [IQR, 83.0 to 96.5]; p<0.001). CONCLUSIONS: The IINS group showed significantly better ophthalmologic and orthoptic outcomes than the INSOD group. The psychological and quality-of-life impact was instead significantly greater in the IINS group. To the best of our knowledge, this is the first multicenter study investigating the clinical features of IIN and comparing the two main subgroups, IINS and INSOD.

Chorioretinal biomarkers in hypothalamic amenorrhea.

PURPOSE: The aim of our study was to evaluate changes in the retinal and choriocapillaris circulations in patients with hypothalamic amenorrhea. METHODS: Prospective, cross-sectional observational study on 25 patients (50 eyes) diagnosed with hypothalamic amenorrhea and 25 age-matched healthy women. Optical coherence tomography angiography (OCTA) was used to evaluate the vessel density (VD) of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris VD layers in whole 6.4 × 6.4-mm image and in fovea grid-based image. In patients' group, systemic parameters were collected: body mass index (BMI), endometrial rhyme thickness, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, insulin, and cortisol. RESULTS: SCP and DCP did not show any statistical difference when comparing patients and controls (all p > 0.05). Differently, choriocapillaris VD in the whole region showed a non-significant tendency toward higher values in the patients group in both eyes (p = 0.038 for right eye [RE], p = 0.044 for left eye [LE]). Foveal choriocapillaris VD was higher in hypothalamic amenorrhea women vs. healthy controls (66.0 ± 2.4 vs. 63.7 ± 6.6%, p = 0.136 for RE; 65.0 ± 2.4 vs. 61.6 ± 7.0%, p = 0.005 for LE). Focusing on correlation with systemic parameters, SCP and DCP foveal density had a medium/high effect size with endometrial rhyme, along with DCP in the fovea area vs. cortisol and SCP in the whole area vs. FSH. CONCLUSION: When comparing hypothalamic amenorrhea patients to healthy subjects, OCTA detected changes in the choriocapillaris layer, showing increased VD in the early stage of the systemic pathology, suggesting that microvascular "compaction" could be a first phase of hypoestrogenism adaptation.

En Face Optical Coherence Tomography Illustrates the Trizonal Distribution of Drusen and Subretinal Drusenoid Deposits in the Macula.

PURPOSE: To analyze the topographic distribution of macular drusen and subretinal drusenoid deposits (SDDs) using single-capture en face spectral domain optical coherence tomography (SD-OCT) imaging. DESIGN: Retrospective case series. METHODS: Analysis of 33 eyes of 20 patients with evidence of SDDs. Structural en face OCT images were reconstructed using a 40-µm-thick slab positioned from 48 to 88 µm above the Bruch membrane. The Early Treatment of Diabetic Retinopathy Study (ETDRS) grid and a rod/cone density map were overlaid on the en face OCT images, and the distribution of different subtypes of SDDs and macular drusen were assessed. RESULTS: A total of 31 eyes (94%) showed a trizonal distribution pattern of drusen and SDDs. Whereas small to large drusen tended to aggregate in the central circle, dot SDDs predominated in the inner ring and the inner portion of the outer ring of the ETDRS grid and ribbon SDDs localized to the outer ring and outside the ETDRS grid. Of note, drusen colocalized to the region of greatest cone density, whereas ribbon SDDs colocalized to the area of greatest rod density. The dot SDDs mapped to the intermediate region with mixed rod and cone representation. CONCLUSION: Dot and ribbon subtypes of SDDs and macular drusen show a characteristic trizonal distribution. The locations of these lesions colocalize according to the different densities of the cones and rods in the retina and may reflect varying pathophysiological activities of these photoreceptor subtypes.

A case of cilioretinal artery occlusion: Diagnostic procedures.

Purpose: To evaluate characteristic imaging findings and functional outcomes of Cilioretinal Artery Occlusion (CLRAO) associated with giant cell arteritis (GCA). Observations: We report the case of a 70-year-old woman presenting with sudden vision loss caused by a GCA-associated-CLRAO in her left eye (LE). A thorough ophthalmologic examination together with optical coherence tomography (OCT), OCT-Angiography (OCT-A), fluorescein angiography and fundus autofluorescence were performed. At presentation, the best corrected visual acuity in the LE was 20/200 and funduscopic examination revealed optic disc edema associated with retinal whitening along the area perfused by the CLRA. After 1 month, OCT and OCT-A revealed an improvement of the retinal edema and a partial reduction of the non-perfused areas in the superficial and deep capillary plexuses, as well as in the outer retina and in the choriocapillaris. Fluorescein angiography showed a reduction in the perfusion of the affected area, a delayed perfusion of the temporal sector of the optic disc, as well as areas of choroidal hypoperfusion in the peripheral temporal retina. The patient's visual acuity did not change during the follow up. Conclusion and importance: Despite a partial recanalization of the occluded vasculature being possible after GCA-associated-CLRAO, the patient's visual prognosis remains poor.

Spontaneous closure of full-thickness macular hole after pars plana vitrectomy for retinal detachment: evidence of ellipsoid zone restoration.

PURPOSE: To describe a case of full-thickness macular hole (FTMH) occurred after pars plana vitrectomy (PPV) for a macula-sparing rhegmatogenous retinal detachment (RRD), which showed a spontaneous closure associated with outer retinal layers restoration. METHODS: Case report. RESULTS: A pseudophakic 69-year-old man underwent PPV for a macula-sparing superior RRD in the right eye (RE). Best corrected visual acuity (BCVA) was 20/20 before surgery. Three weeks after treatment the patient complained about visual impairment, and a FTMH was detected at fundus examination as well as confirmed by optical coherence tomography (OCT) scan. The patient was scheduled for a repeated surgery, but FTMH spontaneously closed eighteen days after its occurrence as demonstrated at OCT showing only a point break of the ellipsoid zone (EZ) and Verhoeff membrane. The subsequent macular OCT scan showed a point-like irregularity at the Verhoeff membrane and regeneration of EZ, associated with a progressive improvement in BCVA. Forty-days after the FTMH occurrence, all the retinal layers were completely restored with a complete clinical recovery. CONCLUSION: FTMH formation and closure after macula-sparing RRD repair is a rare event that could be characterized by spontaneous and gradual anatomical restoration of the EZ associated with visual acuity improvement, underlying the retinal physiology recovery.

Central Serous Chorioretinopathy by Autofluorescence, Enface and SLO-Retromode Imaging.

The aim of our study was to investigate the clinical features of central serous chorioretinopathy (CSC) with autofluorescence (AF), retromode (RM), and enface imaging. This retrospective study was conducted at Fondazione Policlinico Universitario A. Gemelli, IRCCS, Rome (Italy), between September and December 2022. Each patient underwent a complete ophthalmological examination, which included optical coherence tomography (OCT), enface image analysis, AF, and RM imaging. We further evaluated the presence and area of extension of serous retinal detachment and retinal pigment epithelium (RPE) atrophy through AF, RM, and enface imaging. We included 32 eyes from 27 patients (mean age: 52.7 ± 13.3 years). The median AF area was 19.5 mm2 (IQR 6.1-29.3), while the median RM area was 12.3 mm2 (IQR 8.1-30.8), and the median enface area was 9.3 mm2 (IQR 4.8-18.6). RPE atrophy was diagnosed in 26 cases (81.3%) with RM imaging and in 75% of cases with AF. No difference emerged between AF and RM analysis in the detection of central serous detachment in CSC. However, RM imaging showed a high specificity (91.7%) and negative predictive value (84.6%) to detect RPE changes when compared to the AF standard-of-care technique. Thus, RM imaging could be considered an adjunctive imaging method in CSC.

3D Da Vinci robotic surgery: is it a risk to the surgeon's eye health?

Da Vinci three-dimensional (3D) system has been increasingly used in customary surgical settings, gaining fundamental relevance for abdominal, urological, and gynecological laparoscopic surgery. The aim of this research is to evaluate the degree of discomfort and potential changes in the binocular vision and ocular motility of surgical operators, who employ 3D vision systems during Da Vinci robotic surgery. Twenty-four surgeons were enrolled in the study, including twelve who typically use the 3D Da Vinci system and twelve who routinely employ 2D system. Routine general ophthalmological and orthoptic examinations were conducted at baseline (T0), the day before surgery, and 30 min after the 3D or 2D surgery (T1). In addition, surgeons were interviewed using a questionnaire of 18 symptoms, with each item containing three questions regarding the frequency, severity, and bothersomeness of the symptoms, in order to evaluate the degree of discomfort. Mean age at evaluation was 45.28 ± 8.71 years (range 33-63 years). Cover test, uncover test, and fusional amplitude showed no statistically significant difference. After surgery, no statistical difference was observed in the Da Vinci group on the TNO stereotest (p > 0.9999). However, the difference in the 2D group resulted statistically significant (p = 0.0156). Comparing participants (p 0.0001) and time (T0-T1; p = 0.0137), the difference between the two groups was statistically significant. Surgeons using 2D systems reported more discomfort than those using 3D systems. The absence of short-term consequences following surgery with the Da Vinci 3D system is a promising conclusion, considering the numerous advantages of this technology. Nonetheless, multicenter investigations and more studies are required to verify and interpret our findings.

Brolucizumab for Wet Age-Related Macular Degeneration: One-Year Real-World Experience from a Tertiary Center.

INTRODUCTION: The aim of this study was to explore the early efficacy and safety of treatment with intravitreal injections (IVIs) of brolucizumab in patients presenting with neovascular age-related macular degeneration (nAMD) in a real-world setting. METHODS: This retrospective study included 194 eyes of 180 patients with nAMD treated with standard 6-mg IVIs of brolucizumab in our clinic between March 11, 2021, and June 15, 2022. Both treatment-naive (33 eyes) and switch therapy patients (161 eyes) were included in the study. Best corrected visual acuity (BCVA), central subfield thickness (CST), retinal fluid distribution (classified as intraretinal, subretinal, under the pigmented epithelium), treatment intervals, and adverse event rates were collected for analysis. RESULTS: Average follow-up time was 37.2 ± 16.6 weeks. Mean baseline BCVAs were 38.1 ± 4.5 and 41.9 ± 6.7 letters in the treatment-naive and switch therapy groups, with a final gain of 16.0 ± 4.9 (p < 0.0001) and 10.7 ± 5.9 (p < 0.0001) letters in the two groups, respectively. Throughout the study period, CST significantly decreased in both treatment naïve (from 352.0 ± 129.4 to 284.2 ± 93.8 µm; p = 0.0015) and switch therapy (from 369.9 ± 140.5 to 307.4 ± 123.5 µm; p < 0.0001). Significant fluid control rates were achieved at the end of the study period (45% and 27% eyes were completely free of fluid in naïve and switch groups, respectively). Five eyes (2.6%) developed adverse events with different grades of intraocular inflammation and visual outcomes. CONCLUSION: Brolucizumab IVI showed very good anatomical and functional outcomes in both naive and switch patients in this real-world experience. Nevertheless, even showing a favorable risk/benefit profile, clinicians and patients should be aware of the possibility of a small rate of severe complications.

Orbital myositis and scleritis after anti-SARS-CoV-2 mRNA vaccines: A report of three cases.

PURPOSE: To report three cases of ocular myositis and scleritis, bilateral scleritis and unilateral single muscle myositis after mRNA COVID-19 vaccination. METHODS: Case series of three patients who presented to the Orbit Outpatient Service of Fondazione Policlinico Universitario A. Gemelli with a history of unilateral proptosis, diplopia and pain, bilateral red eye and pain during eye movements and unilateral proptosis and inconstant diplopia respectively with onset 5-10 days after m-RNA COVID-19 vaccine. A thorough hematologic work up and orbital contrast enhanced magnetic resonance imaging (MRI) in patients with proptosis was performed. RESULTS: Patients were females, 64, 58 and 45 years old respectively. MRI showed enlargement of all right rectus muscles, with both muscle belly and insertion involvement in the first case associated to right scleritis. A bilateral scleritis was diagnosed in the second patient and a single muscle myositis in the third patient. Serological tests excluded thyroid diseases. The first and second patient were treated respectively with oral and topical glucorticoids with a complete clinical response. Two 2 cycles of oral non-steroidal anti-inflammatory drugs were administered to the third patient with a partial response. CONCLUSION: As far as we know these are the first report of orbital myositis and scleritis presenting after mRNA BNT162b2 vaccine (Pfizer/BioNTech) and mRNA-1273-(Moderna) vaccine, an uncommon effect of a likely autoimmune reaction triggered by the virus antigen.

Bilateral papilledema associated with retinal hemorrhagic appearance as earliest sign of spinal cord tumor.

INTRODUCTION: To report a case of a 57-years-old female patient who presented with prominent bilateral proptosis and swollen disks. CASE DESCRIPTION: A 57-year-old obese patient admitted to our ophthalmic department complaining of bilateral sense of eye swelling and mild blurring vision. The anterior segment and pupillary reflex were normal on ophthalmological testing. Likewise, eye movements were preserved and she did not report diplopia in any position of gaze. Dilated fundus examination revealed bilateral hemorrhagic papilledema, pre-retinal hemorrhages in both eyes, dot and blot hemorrhages in the peripheral retina. Visual acuity was 20/20 in both eyes. Routine hematological investigations revealed increased both Von Willebrand factor and ristocetin factor and LAC positivity. The lumbar puncture (LP) showed elevated cerebrospinal fluid (CSF) proteins. Magnetic resonance imaging (MRI) with contrast of brain and spinal cord showed signs of intracranial hypertension and the presence of two lesions in continuity with each other respectively located at T12-L1 and L1-L2. Radiologic features were compatible with the diagnosis of ependymoma. A surgical procedure was conducted and confirmed the diagnosis after anatomical pathology analysis. CONCLUSION: Although rare, bilateral hemorrhagic swollen disks could be an early sign of spinal cord tumors, in particular ependymomas.

Long-term follow-up of surgical treatment of thyroid-associated orbitopathy restrictive strabismus.

Objective: Thyroid-associated orbitopathy (TAO) is the most frequent cause of extraocular muscle enlargement, with consecutive restrictive strabismus. The main muscles involved are inferior and medial rectus, resulting in horizontal esotropia and/or vertical strabismus. Surgery may either establish or improve binocular single vision. The aim of the present study is to describe long-term follow-up of patients who underwent horizontal or vertical TAO strabismus surgery. Methods: This observational retrospective study included 29 patients suffering from either vertical or horizontal TAO strabismus and diplopia, of whom 11 underwent bilateral medial recti muscle recession (Group A) and 18 underwent unilateral inferior rectus muscle recession (Group B). The endpoint of the study was the assessment of changes in deviation angle and diplopia across four time points (baseline, 7 days, 6 months, and 24 months) in each group. Results: In Group A, the horizontal deviation angle significantly decreased 7 days after intervention (p < 0.001), without modifications overtime. In Group B, both deviation angles in primary and down-gaze position significantly decreased from baseline, both 7 days after surgery (p < 0.001) and at 6 months (p = 0.040). An overcorrection, with an inversion of vertical deviation angle, was observed across the different time points. Conclusions: Horizontal TAO strabismus correction leads to significant improvements of deviation angle and diplopia, with a stable undercorrection overtime. Inferior rectus recession leads to more unstable results, with a trend towards overcorrection limited to the first 6 months after surgery.
