RESUMO
PURPOSE: To determine changes in choroidal volume (CV) and choroidal vascularity index (CVI) in patients on hydroxychloroquine (HCQ) therapy. METHODS: Retrospective analysis of patients on HCQ therapy. CV and CVI were assessed below the central foveal region on spectral-domain optical coherence tomography using an automatic denoising and localization algorithm. CV and CVI were compared with age-matched controls. Regression analyses were performed to generate associations between CV and CVI with demographics and HCQ treatment parameters. Associations were assessed using a generalized estimating equation model adjusted for intra-subject inter-eye correlations. RESULTS: A total of 137 adult patients (23 males and 114 females) were included. Mean age was 45.6 ± 13.7 years and most patients identified as Caucasian (79%). Total duration of HCQ therapy ranged from 3 months to 20 years. Daily HCQ intake varied from 150-600 mg (mean = 304 mg), while cumulative doses ranged from 18-2,800 g. At presentation, the median CV was 0.51 (IQR:0.356-0.747) mm, and median CVI was 0.559 (IQR:0.528-0.578). Increased cumulative HCQ dose was associated with decreased CV (p = 0.006). Compared to age-matched controls, CV, CVI, and luminal area were significantly lower in the study group (p = 0.0003, 0.0001, and 0.0002). CONCLUSION: In this study, we present a novel analysis of key biomarkers which predate the occurrence of HCQ retinopathy. Choroidal volume and vascularity index are significantly reduced in patients on HCQ therapy, especially at higher cumulative doses. These findings suggest new tools to guide medical decision-making for patients receiving HCQ therapy for rheumatologic diseases.

AIMS OF THE STUDY: Vitamin A deficiency retinopathy is a potentially blinding disease. In developed countries, vitamin A deficiency due to malnutrition is rare. However, vitamin A deficiency can be caused by malabsorption resulting from bowel resection or medication. In this retrospective study, we present five cases of vitamin A deficiency retinopathy related to malabsorption secondary to medical interventions. METHODS: Electronic charts over a ten-year period (2012-2022) were screened for vitamin A deficiency retinopathy. Only patients with vitamin A deficiency confirmed by laboratory tests were included. Symptoms, medical history, visual acuity, optical coherence tomography, fundus autofluorescence, electrophysiological examination, and vitamin A levels were reviewed. RESULTS: Five eligible cases were identified. Median age was 44.7 years (range 22.2-88.9), median duration of ocular symptoms prior to diagnosis was 14 months, and median visual acuity was 1.0 (range 0.5-1.0, Snellen, decimal). Three patients had a history of bariatric surgery, one patient had a small bowel resection and was on octreotide treatment, and one patient suffered from cystic fibrosis and had a history of small bowel resection and severe hepatopathy. Optical coherence tomography showed various abnormalities, including a reduced interdigitation zone, subretinal drusenoid deposits, and a thinned outer nuclear layer. Electroretinogram findings ranged from abnormal oscillatory potentials to non-recordable rod responses. CONCLUSIONS: Vitamin A deficiency retinopathy can occur following medical interventions associated with malabsorption. In cases of night blindness, vitamin A levels should be measured.

PURPOSE: To evaluate the impact of drusen-like deposits (DLD) on retinal layer integrity and retinal function by optical coherence tomography (OCT) and multifocal electroretinography (mfERG) in patients with systemic lupus erythematosus (SLE). METHODS: We identified 66 eyes of 33 SLE patients treated with hydroxychloroquine (HCQ) that were categorized into two groups according to whether DLDs were present (34 eyes, Group One) or absent (32 eyes, Group Two). The groups were matched for age, sex, HCQ treatment duration, daily, and cumulative dosage. OCT (retinal layer thicknesses, central retinal thickness, CRT) and mfERG concentric ring analysis were analyzed and compared. RESULTS: CRT was significantly thicker in Group One compared to Group Two (273.21 ± 3.96 vs. 254.5 ± 7.62) (p = 0.023). Group One also demonstrated an overall thicker retinal pigment epithelium compared to Group Two; however, the other outer retinal layers, outer nuclear layer, and photoreceptor layer were found to be significantly thinner in Group One compared to Group Two. We found no differences in mfERG parameters between the two groups. CONCLUSIONS: DLDs in SLE patients lead to abnormal central retinal layer thickness, which has no measurable impact on cone-mediated retinal function assessed by mfERG.
RESUMO
PURPOSE: To analyze the features of myopic macular schisis (MMS) in different retinal layers and to explore the role of Müller cells in the pathophysiology of such condition. METHODS: Spectral-domain optical coherence tomography (SD-OCT) images of myopic eyes with staphyloma and macular schisis were reviewed. The morphological features of MMS were analyzed and correlated with their geographical location in the parafoveal and perifoveal region. A biomechanical model was adopted to explain MMS morphological differences. The effect of the different schisis subtypes with best corrected visual acuity (BCVA) was also explored. RESULTS: A total of 36 eyes from 26 patients were included in this study. MMS was classified into inner, middle and outer retinal subtypes. The prevalence of middle retinal schisis was significantly lower in the parafovea, within a central 3 mm-diameter circle (p < 0.001) centered at the fovea . The prevalence of inner retinal schisis was significantly higher outside the central 3-mm diameter circle, in the perifoveal region (p < 0.001). No significant differences were noted in the prevalence of outer retinal schisis for these two locations (p = 0.475). The presence of middle retinal schisis within the central 3-mm diameter circle showed a weak association with lower BCVA (p = 0.058). The presence of outer retinal schisis within the central 3-mm diameter circle was significantly related with lower BCVA (p = 0.024). CONCLUSION: Three major forms of MMS are distinguished: inner, middle and outer retinal schisis. This classification may have clinical importance as only the outer grade of schisis was associated with vision loss.
RESUMO
BACKGROUND: Fabry disease (FD) is a potentially lethal lysosomal disorder with systemic vascular changes. Previous studies demonstrated retinal vascular involvement using optical coherence tomography angiography (OCTA) in affected patients; Aim: To analyze and quantify the retinal vasculature measuring vessel density (VD), vessel length density (VLD), and the ratio of VD to VLD (VD/VLD) in superficial capillary plexuses (SCP) and deep capillary plexuses (DCP) using OCTA in patients with FD and to show whether they differ from healthy controls (HC); Patients and methods: Single-center, retrospective, consecutive cohort study of patients with genetically proven FD. Patients underwent an ophthalmological examination including OCTA. VD, VLD, foveal avascular zone (FAZ), and the VD/VLD were compared to an HC group using a linear mixed model; Results: A statistically significant difference in the VLD and VD/VLD of DCP was observed between the two groups (p < 0.001). Using ROC curves with AUC and Youden's Index, a cut-off value for differentiating both groups using VD/VLD in DCP FD with high specificity and high sensitivity was established; Conclusions: FD and HC groups seem to be separable using the VD/VLD ratio in DCP. This new biomarker might differentiate changes in the retinal microvasculature that are not detectable by VD or VLD alone.
RESUMO
PURPOSE: Hydroxychloroquine (HCQ) can cause irreversible damage to the retina, especially when taken over longer periods. The American Academy of Ophthalmology recommends a regimen for dosing, screening and monitoring of patients treated with HCQ. We present an unusual case of a rapid development of severe HCQ-associated-retinopathy already after 2 years after commencing HCQ treatment. METHODS: Observational case report. Clinical examination, optical coherence tomography (OCT), fundus autofluorescence imaging (FAF), perimetry, full-field & multifocal electroretinography (ERG) were performed. Ancillary tests included neoplastic and paraneoplastic work-up, vitamin levels and whole exome sequencing, in order to rule out other potential causes of a panretinal degeneration. RESULTS: We report on a 58-year-old woman with rheumatoid arthritis, treated initially with 200mg HCQ daily for 1 year (daily dose 3.6mg/kg), then 400mg daily for 1 year (daily dose 7.2mg/kg), and a cumulative dose of 216 g. Her medical history was otherwise unremarkable. No family history for inherited retinal conditions. She was referred due to a rapid and sudden progressive and severe concentric visual field constriction, two years after commencing HCQ treatment. CONCLUSION: This case of a rapid-onset, severe panretinal degeneration shortly after start of HCQ treatment suggests underlying mechanisms and risk factors for HCQ toxicity in addition to those previously reported, and a potential need for supplementary screening tests to prevent HCQ toxicity. AAO dosing guidelines of 5 MG/KG should be strictly adhered to in patients receiving HCQ therapy.
RESUMO
PURPOSE: To document a peculiar case of optic disk pit-associated maculopathy with extensive nasal retinoschisis with lamellar outer retinal hole. METHODS: A 41-year-old woman presented to the eye clinic complaining of new photopsias and enlargement of the blind spot in the left eye. Uncorrected visual acuity was 20/20 in both eyes. Fundus examination of the left eye revealed an anomalous appearing optic nerve with a gray oval depression at the temporal margin of the disk consistent with an optic disk pit. RESULTS: Optical coherence tomography confirmed the presence of the pit and demonstrated outer plexiform layer schisis superonasal to the fovea and extensive inner and outer retinal schisis nasal to the nerve extending to the equator. A large lamellar outer retinal hole was noted nasal to the disk without associated retinal detachment. The vitreous appeared to be attached over the nasal retina. CONCLUSION: Multimodal imaging revealed an unusual optic disk pit-associated retinopathy with dramatically more extensive retinoschisis and a lamellar outer retinal hole nasal to the nerve despite the temporal location of the pit. Although the precise pathophysiologic mechanisms are not fully understood, forces associated with the vitreo-retinal adhesion may have contributed to the distribution of the schisis in this case.

Background: The relevance of drusen-like deposits (DLD) in patients with systemic lupus erythematosus (SLE) is to a large extent uncertain. Their genesis is proposed to be correlated to immune-complex and complement depositions in the framework of SLE. The intention of this study was to determine potential morphological differences in the choroid and retina as well as potential microvascular changes comparing two cohorts of SLE patients divergent in the presence or absence of DLD using multimodal imaging. Methods: Both eyes of 16 SLE patients with DLD were compared to an age- and sex-matched control-group consisting of 16 SLE patients without detectable DLD. Both cohorts were treated with hydroxychloroquine (HCQ) and did not differ in the treatment duration or dosage. Using spectral-domain optical coherence tomography (SD-OCT) choroidal volume measures, choroidal vascularity indices (CVI) and retinal layer segmentation was performed and compared. In addition, by the exploitation of optical coherence tomography angiography vascular density, perfusion density of superficial and deep retinal capillary plexuses and the choriocapillaris were analyzed. For the choroidal OCT-scans, a subset of 51 healthy individuals served as a reference-group. Results: CVI measures revealed a significant reduction in eyes with DLD compared to healthy controls (0.56 (0.54−0.59) versus 0.58 (0.57−0.59) (p = 0.018) and 0.56 (0.54−0.58) versus 0.58 (0.57−0.60) (p < 0.001)). The photoreceptor cell layer presented significant thinning in both eyes of subjects with DLD compared to control subjects without DLD (68.8 ± 7.7 µm vs. 77.1 ± 7.3 µm for right eyes, p = 0.008, and 66.5 ± 10.5 µm vs. 76.1 ± 6.3 µm for left eyes, p = 0.011). OCTA scans revealed no significant changes, yet there could be observed numerically lower values in the capillary plexuses of the retina in eyes with DLD than in eyes without DLD. Conclusions: Our results illustrated significant alterations in the choroidal and retinal analyzes, suggesting a correlation between DLD and the progression of inflammatory processes in the course of SLE leading to retinal degeneration. For this reason, DLD could serve as a biomarker for a more active state of disease.
RESUMO
PURPOSE: To determine prevalence of probable polypoidal choroidal vasculopathy (PCV) among White patients with neovascular age-related macular degeneration (nAMD) using non-indocyanine green angiography (ICGA) criteria DESIGN: Multicenter, multinational, retrospective, cross-sectional study. METHODS: A total of 208 treatment-naive eyes from Hispanic and non-Hispanic White individuals diagnosed with nAMD were included. All underwent color fundus photography (CFP), optical coherence tomography (OCT), and fluorescein angiography (FFA). De-identified images of study eyes were sent to 2 groups of graders. Group 1 reviewed CFP, OCT, and FFA to confirm nAMD diagnosis. Group 2 reviewed CFP and OCT to determine highly suggestive features for PCV. Probable PCV diagnosis defined as the presence of ≥2 of 4 highly suggestive features for PCV: notched or fibrovascular pigment epithelial detachment (PED) on CFP, sharply-peaked PED, notched PED, and hyperreflective ring on OCT. RESULTS: Eleven eyes were excluded because of poor image quality (6) or non-nAMD diagnosis (5). Of 197 eligible eyes (197 patients), the mean age (SD) was 78.8 years (8.9), 44.2% were men, 26.4% were Hispanic, and 73.6% were non-Hispanic White individuals; 41.1%, 23.4%, 9.1%, and 2.5% had ≥1, ≥2, ≥3, and 4 highly suggestive features. Results showed that 23.4% (95% CI, 17.6%-29.9%) had probable PCV diagnosis. Predominantly occult CNV was more frequently found in probable PCV than nAMD subgroup (84.8% vs 64.9%, P = .01). Hispanic White individuals had a lower prevalence of probable PCV than non-Hispanic White individuals (9.6% vs 28.2%, P = .006) CONCLUSIONS: These findings suggest that probable PCV occurs between 17.6% and 29.9% in White individuals with nAMD, and more commonly in non-Hispanic than in Hispanic White individuals.

BACKGROUND: To describe cases of retinal vascular events shortly after administration of mRNA or adenoviral-vectored COVID-19 vaccines. DESIGN: Retrospective, multicenter case series. METHODS: Six cases of retinal vascular events shortly after receiving COVID-19 vaccines. RESULTS: A 38-year-old, otherwise healthy male patient presented with branch retinal arterial occlusion four days after receiving his second dose of SARS-CoV-2 vaccination with Comirnaty® (BioNTech®, Mainz, Germany; Pfizer®, New York City, NY, USA). An 81-year-old female patient developed visual symptoms twelve days after the second dose of SARS-CoV-2 vaccination with Comirnaty® and was diagnosed with a combined arterial and venous occlusion in her right eye. A 40-year-old male patient noticed blurry vision five days after his first dose of SARS-CoV-2 vaccination with Comirnaty® and was diagnosed with venous stasis retinopathy in his left eye. A 67-year-old male was diagnosed with non-arteritic anterior ischemic optic neuropathy in his right eye four days after receiving the first dose of Vaxzevria® (AstraZeneca®, Cambridge, UK). A 32-year-old man presented with a sudden onset of a scotoma two days after receiving the second dose of SARS-CoV-2 vaccination with Spikevax® (Moderna, Cambridge, UK) and was diagnosed with a circumscribed nerve fiber infarction. A 21-year-old female patient developed an acute bilateral acute macular neuroretinopathy three days after receiving the first dose of SARS-CoV2-vaccine Vaxzevria® (AstraZeneca®, Cambridge, UK). CONCLUSION: This case series describes six cases of retinal vascular events shortly after receiving mRNA or adenoviral-vectored COVID-19 vaccines. The short time span between received vaccination and occurrence of the observed retinal vascular events raises the question of a direct correlation. Our case series adds to further reports of possible side effects with potential serious post-immunization complications of COVID-19 vaccinations.
RESUMO
PURPOSE: This study aims to describe vessel density differences in tractional versus exudative macular oedema with the aid of novel custom imaging analysis techniques. METHODS: In this retrospective study, patients with exudative and tractional macular oedema were imaged with optical coherence tomography (OCT), en-face OCT, OCT-angiography and fluorescein angiography. A novel image processing algorithm was developed to extrapolate data from the vessel density maps. RESULTS: Forty-one eyes of 36 patients were included. A total of 30 control eyes comprised the control group. At the deep capillary plexus (DCP), exudative eyes presented with a vessel density of 62.12 ± 5.7, significantly higher if compared to both tractional lamellar macular hole (57.6 ± 4.6, p = 0.004) and controls (52.07 ± 2.3, p < 0.001). At the superficial capillary plexus (SCP), there were no differences in vessel density between exudative eyes (51.9 ± 4.4) and both the tractional lamellar hole (54.9 ± 3.1, p = 0.083) and the control (51.72 ± 2.2, p = 0.083) groups. In the exudative subgroup, there was a direct correlation between areas of low flow and those of high flow at both the DCP and SCP (p = 0.001 and p = 0.042, respectively). CONCLUSIONS: Intraretinal expansion of fluid may cause the displacement of the surrounding retinal parenchyma and capillaries.

BACKGROUND: To date, there are no studies associating the dried blood spot (DBS) levels of globotrioasylsphingosine (lysoGb3) with quantitative optical coherence tomography angiography (OCTA) parameters in Fabry disease (FD) patients. Here, we aimed to investigate the association between OCTA vessel density (VD), vessel length density (VLD) with DBS lysoGb3. METHODS: A retrospective, single center analysis of all consecutive FD patients enrolled at the Department of Ophthalmology of the University Hospital of Zurich from 1 December 2017 to 9 September 2020. An association between VD and VLD detected by OCTA and lysoGb3 was investigated using a linear mixed model. RESULTS: A total of 57 FD patients (23 male, 34 female; 109 eyes) were included. Forty-one patients suffered from the classic phenotype and 16 from the later-onset phenotype. LysoGb3 inversely correlated with VD and VLD in both the superficial (VD: p = 0.034; VLD: p = 0.02) and deep capillary plexus (VD: p = 0.017; VLD: p = 0.018) in the overall FD cohort. CONCLUSIONS: Our study shows an association between lysoGb3 and OCTA VD and VLD. This supports the hypothesis that quantitative OCTA parameters might be useful as diagnostic biomarkers for evaluating systemic involvement in FD, and possibly other diseases.
RESUMO
Inherited retinal diseases, which results from mutations in over 260 identified genes, affect more than 2 million people globally. The diseases mostly cause severe vision loss in young working population and have severe impact on social economic status of the population. Advances in retinal imaging techniques along with developments in gene identification and cell biology techniques have yielded to a better understanding of the genetic and biochemical mechanisms causing these diseases. Retinal imaging along with through ophthalmological examination is essential to make an accurate diagnosis, to decrease the burden of unneccessary anciliary tests and to select the potential patients that can get benefit from the gene treatment. The purpose of the review is to yield an update on inherited retinal diseases by highlighting microstructural changes in retina and to summarize the retinal changes detected by currently available multimodal imaging techniques.

PURPOSE: To report the characteristics of non-proliferative fellow eyes in patients with unilateral proliferative macular telangiectasia type 2 (MacTel). METHODS: This was a multicenter, retrospective study and included fellow eyes of eyes with subretinal neovascular membrane (SRNVM). Multimodal imaging including fundus photography, optical coherence tomography (OCT), and OCT angiography (OCTA) was performed. OCT and OCTA measurements included central macular thickness (CMT), subfoveal choroidal thickness (SFCT), foveal avascular zone (FAZ) area and qualitative parameters such as distortion or enlargement of FAZ, increased inter-vascular spacing, dilated, tortuous vessel at margin of FAZ, crowding of vessel, and loss of choriocapillaris (CC). RESULTS: Thirteen fellow eyes of 13 patients with mean age of 63.6 ± 12.0 years were included. Fellow eyes had various stages of the diseases - stage 2 (four eyes), 3 (six eyes), and 4 (three eyes). OCTA showed increased intervascular spacing (8; 61.5%), dilated (11; 84.6%), and elongated vessels (8; 61.5%) at the margin of the FAZ, crowding of vessels (6; 46.2%), capillary non-perfusion areas outside the FAZ (4; 30.8%), and areas of CC loss (4; 30.8%). Mean follow-up was 9.1 ± 12.9 months. Out of six eyes with follow-up of ⩾12 months, two developed SRNVM at 18 and 33 months with OCTA showing crowding and entanglement of dilated retinal vessels in deep capillary plexus at baseline which corresponded to the area affected by SRNVM. CONCLUSION: Fellow eyes of proliferative MacTel showed established disease stages on OCTA with progressive capillary crowding and entanglement of vessels likely corresponding to the future site of SRNVM.

PURPOSE: The spectrum of intraocular and systemic findings in patients with ocular syphilis is described. Persistent visual dysfunction and structural abnormality, in spite of targeted antibiotic therapy, were identified and analysed. METHODS: Patients with ocular syphilis who were treated at University Hospital Zurich (USZ) between 2010 and 2018 were included in this study. General characteristics, ocular manifestation and visual function (best-corrected visual acuity [BCVA], visual field) before and after treatment were analysed retrospectively. RESULTS: Ocular syphilis was diagnosed in one female and 16 male patients (median age 42 years, range 22 to 53 years). A bilateral infection was present in 11 cases, and 28 of 34 eyes were affected (82%). Manifestations included anterior (n = 3), intermediate (n = 4), posterior (n = 10) uveitis, as well as panuveitis (n = 5) and papillitis (n = 6). Abnormal liquor findings were present in 8 patients (47%). Six patients were human immunodeficiency virus (HIV) positive. In all patients, intravenous benzyl penicillin was initiated and led to inactivation of intraocular inflammation. Before the initial intravenous treatment, all patients received one dose of steroids orally (Prednisone [PDN] 50 to 70 mg). Seven patients had systemic steroids added over the course of the antibiotic treatment being gradually decreased during and after the antibiotic treatment. The initial median BCVA of all affected eyes (n = 28) of 17 patients was 0.1 logMAR (0.8 decimal), range 2.8 to - 0.1 logMAR (light perception to 1.25 decimal). At the last visit, the median BCVA was 0 logMAR, range 0.4 to - 0.1 logMAR (0.4 to 1.25 decimal). Median follow-up time was 11 months (range 3 to 60 months). At the last visit, BCVA of 4 eyes (3 patients) was ≤ 0.6. Six eyes of 5 patients had a persisting scotoma with central visual field defects. Morphologically, disintegration and irregularities of outer retinal layers after central retinitis (5 eyes) and atrophy of the peripapillary retinal nerve fibre layer (4 eyes) after papillitis correlated with abnormal vision. CONCLUSIONS: The spectrum of ocular manifestations in syphilis is broad. Despite targeted antibiotic therapy, more than a third of affected eyes had lasting abnormal vision. Patients with papillitis and retinitis were at an increased risk for persistent visual dysfunction.

PURPOSE: To explore morphologic characteristics of choroidal lesions in patients with disseminated Mycobacterium chimaera infection subsequent to open-heart surgery. METHODS: Nine patients (18 eyes) with systemic M. chimaera infection were reviewed. Activity of choroidal lesions were evaluated using biomicroscopy, fundus autofluorescence, enhanced depth imaging optical coherence tomography, fluorescein angiography/indocyanine green angiography, and optical coherence tomography angiography. Relationships of choroidal findings to systemic disease activity were sought. RESULTS: All 9 male patients, aged between 49 and 66 years, were diagnosed with endocarditis and/or aortic graft infection. Mean follow-up was 17.6 months. Four patients had only inactive lesions (mild disease). In all five patients (10 eyes) with progressive ocular disease, indocyanine green angiography was superior to other tests for revealing new lesions and active lesions correlated with hyporeflective choroidal areas on enhanced depth imaging optical coherence tomography. One eye with a large choroidal granuloma developed choroidal neovascularization. Optical coherence tomography angiography showed areas with reduced perfusion at the inner choroid. All 5 patients with progressive ocular disease had evidence of systemic disease activity within ±6 weeks' duration. CONCLUSION: Choroidal manifestation of disseminated M. chimaera infection indicates systemic disease activity. Multimodal imaging is suitable to recognize progressive ocular disease. We propose ophthalmologic screening examinations for patients with M. chimaera infection.
