Discrimination ability of central visual field testing using stimulus size I, II, and III and relationship between VF findings and macular ganglion cell thickness in chiasmal compression.

PURPOSE: To compare the relationship between macular ganglion cell layer (mGCL) thickness and 10-2 visual field (VF) sensitivity using different stimulus sizes in patients with temporal hemianopia from chiasmal compression. METHODS: A cross-sectional study was conducted involving 30 eyes from 25 patients with temporal VF loss on 24-2 SITA standard automated perimetry due to previous chiasmal compression and 30 healthy eyes (23 controls). Optical coherence tomography (OCT) of the macular area and 10-2 VF testing using Goldmann stimulus size I (GI), II (GII), and III (GIII) were performed in the Octopus 900 perimeter. For the sake of analysis, mGCL thickness and VF data were segregated into four quadrants (two temporal and two nasal) and two halves (temporal and nasal) centered on the fovea, in order to evaluate separately both the severely affected nasal hemi-retina corresponding to the temporal VF sectors and the subclinically affected temporal hemi-retina corresponding to the nasal VF sectors. Data from patients and controls were compared using generalized estimated equations. The discrimination ability of GI, GII, and GIII was evaluated, as was the correlation between mGCL and 10-2 VF sensitivity using GI, GII, and GIII. RESULTS: All mGCL parameters in the nasal and temporal halves of the retina were significantly reduced in patients compared to controls. 10-2 VF test sensitivity using GI, GII, and GIII was significantly lower in patients than in controls (p≤0.008) for all parameters, except the three nasal divisions when using GI (p = 0.41, 0.07 and 0.18) Significant correlations were found between temporal VF sectors (all stimulus sizes) and the corresponding nasal mGCL measurements, with similar discrimination ability. Significant correlations were also observed between all three nasal VF divisions and the corresponding temporal mGCL thickness when using stimulus sizes I and II, but not stimulus size III. CONCLUSIONS: On 10-2 VF testing, GII outperformed GI and GIII with regard to discrimination ability and structure-function correlation with mGCL thickness in the subclinically affected nasal part of the VF in patients with chiasmal compression. Our findings suggest that the use of GII can enhance the diagnostic power of 10-2 VF testing in early cases of chiasmal compression, although further studies are necessary to support this conclusion.

Metastatic and aggressive renal cell carcinoma mimicking a unilateral choroidal tuberculoma / Carcinoma de células renais metastático grave mimetizando tuberculoma de coroide unilateral

ABSTRACT Ocular metastases from systemic tumors are uncommon. The choroid is the most frequent target, with a preference for elderly individuals. Lung cancer is the predominant primary tumor that metastasizes to the eyes in males, although other ocular conditions such as uveitis and retinal lesions can mimic secondary tumor implants in ocular tissues. On fundoscopy, choroidal metastasis resembles other infectious processes, especially choroidal tuberculoma. Therefore, patients presenting with choroidal masses should undergo detailed clinical examinations, especially if the mass is the first manifestation of a systemic and severe disease. In this report, we describe a young man with a metastatic choroidal tumor secondary to papillary renal cell carcinoma mimicking a unilateral choroidal tuberculoma.

RESUMO A disseminação metastática ocular de tumores sistêmicos é incomum, ocorrendo principalmente na coroide e em pacientes idosos. O câncer de pulmão é considerado o principal tumor metastático ocular em homens, contudo, outras doenças oculares, como as uveítes e lesões retinianas, podem mimetizar os implantes secundários tumorais nos tecidos oculares. O aspecto fundoscópico das neoplasias da coroide pode apresentar similaridade com outros processos infecciosos, especialmente o tuberculoma de coroide. Dessa forma, a investigação clínica detalhada é de grande importância no diagnóstico de pacientes com massas coroideanas, especialmente quando configuram a primeira manifestação de uma doença sistêmica e grave. Relatamos um caso raro de metástase coroideana como primeira manifestação clínica do carcinoma de células renais em um homem jovem, mimetizando um tuberculoma de coroide.

Simultaneous Unilateral Abducens Nerve Palsy and Contralateral Anterior Ischaemic Optic Neuropathy as the Presenting Signs of Giant Cell Arteritis.

Ischaemic optic neuropathy is the most common, feared, and recognised ocular manifestation of giant cell arteritis (GCA), while extraocular muscle palsy rarely occurs in the disease. Overlooking the diagnosis of GCA in aged patients with acquired diplopia and strabismus is not only sight- but also life-threatening. Here, we present, for the first time, a case of unilateral abducens nerve palsy and contralateral anterior ischaemic optic neuropathy as the presenting signs of GCA in a 98-year-old woman. Prompt diagnosis and treatment prevented further visual loss and systemic complications and allowed for rapid resolution of the abducens nerve palsy. We also aim to discuss the possible pathophysiological mechanisms of diplopia in GCA and to emphasise that acquired cranial nerve palsy must raise suspicion of this severe disease in elderly patients, particularly in association with ischaemic optic neuropathy.

Visual Hallucinations as a Major Manifestation of Posterior Reversible Encephalopathy Syndrome: Case Report and Literature Review.

We evaluated a 48-year-old woman who had visual hallucinations (VHs) as a major presenting sign of posterior reversible encephalopathy syndrome (PRES). Despite her mild loss of vision, she described various hallucinations after awakening from a comatose state days after a motorcycle collision. VHs are usually accompanied by more severe loss of vision, yet our case and literature review indicate that sudden onset of formed VHs should suggest a possible diagnosis of PRES in patients who have large fluctuations in blood pressure, renal failure, or autoimmune dysfunction, as well as in patients taking cytotoxic agents.

A standardized method to quantitatively analyze optical coherence tomography angiography images of the macular and peripapillary vessels.

BACKGROUND: Optical coherence tomography angiography (OCTA) is a relatively new non-invasive imaging technique to evaluate retinal vascular complexes. However, there is still a lack of standardization and reproducibility of its quantitative evaluation. Furthermore, manual analysis of a large amount of OCTA images makes the process laborious, with greater data variability, and risk of bias. Therefore, the aim of this study is to describe a fast and reproducible quantitative analysis of the foveal avascular zone (FAZ), macular superficial and deep vascular complexes (mSVC and mDVC, respectively), and peripapillary superficial vascular complex (pSVC) in OCTA images. METHODS: We survey models and methods used for studying retinal microvasculature, and software packages used to quantify microvascular networks. These programs have provided researchers with invaluable tools, but we estimate that they have collectively achieved low adoption rates, possibly due to complexity for unfamiliar researchers and nonstandard sets of quantification metrics. To address these existing limitations, we discuss opportunities to improve effectiveness, affordability, and reproducibility of microvascular network quantification with the development of an automated method to analyze the vessels and better serve the current and future needs of microvascular research. OCTA images of the macula (10°x10°, 15°x15°, or 20°x20° centered on the fovea) and peripapillary area (15 × 15º centered on optic nerve head) were exported from the device and processed using the open-source software Fiji. The mSVC, mDVC, and pSVC were automatically analyzed regarding vascular density in the total area and four sectors (superior, inferior, nasal, and temporal). We also analyzed the FAZ regarding its area, perimeter, and circularity in the SVC and DVC images. RESULTS: We developed an automated model and discussed a step by step method to analyze vessel density and FAZ of the macular SVC and DVC, acquired with OCTA using different fields of view. We also developed an automated analysis of the peripapillary SVC. CONCLUSION: Our developed automated analysis of macular and peripapillary OCTA images will allow a fast, reproducible, and precise quantification of SVC, DVC, and FAZ. It would also allow more accurate comparisons between different studies and streamlines the processing of images from multiple patients with a single command.

Chorioretinal abnormalities in idiopathic intracranial hypertension: case reports.

BACKGROUND: Papilledema is the main ocular finding in patients with idiopathic intracranial hypertension (IIH) although several chorioretinal abnormalities may also occur and contribute to visual loss. The purpose of this paper is to describe two cases of chorioretinal abnormalities associated with idiopathic intracranial hypertension: one with choroidal folds and another with polypoidal choroidal vasculopathy, an extremely unusual ocular complication in the disease. CASE PRESENTATION: Case 1: A 47-year-old woman previous diagnosed with idiopathic intracranial hypertension treated with weight loss and acetazolamide that over the following 6 months had optic disc edema gradually resolved. The patient was follow-up for a period of 10 years and the papilledema disappeared, but choroidal folds remained unchanged. Case 2: A 61-year-old female patient was seen as a follow-up examination of a 5-year history of IIH that presented with papilledema. The patient was asymptomatic but fundoscopy evaluation revealed a yellowish white peripapillary subretinal nodular lesion temporally in OD. Multimodal imaging studies were made, and the patient was diagnosed with a rare and just recent described association of IIH and polypoidal choroidal vasculopathy. CONCLUSION: Papilledema, RNFL and retinal ganglion cell loss are the most common structural complications of IIH, but chorioretinal complications are important findings and should be carefully evaluated in such patients. Awareness of such occurrence and the use of appropriated clinical and multimodal imaging studies are of great importance for its early detection, leading to proper treatment and prevention of further visual loss.

Electroretinography reveals retinal dysfunction in Parkinson's disease despite normal high-resolution optical coherence tomography findings.

INTRODUCTION: Parkinson's disease (PD)-associated inner retinal abnormalities, particularly the retinal ganglion cells (RGC) layer, on optical coherence tomography (OCT) have recently gained importance as a biomarker of non-motor involvement of the disease but functional RGC evaluation using photopic negative response (PhNR) has not yet been determined. This study aims to compare structural and functional findings of the retina and optic nerve in PD with healthy controls (CT) including PhNR and OCT. METHODS: Forty-one eyes of 21 PD patients and 38 eyes of 19 CT underwent ophthalmic examination including visual contrast sensitivity test (CS), OCT, light-adapted full-field electroretinography (ffERG), and PhNR. OCT was used to measure the peripapillary retinal nerve fiber layer, the segmented macular layers, and the choroid. For functional parameters, CS, ffERG (oscillatory potentials, photopic response, 30 Hz-flicker), and PhNR waves were used. Measurements were compared using generalized estimating equation and significance was set at P ≤ 0.05. RESULTS: The PD group presented a significantly lower mono- and binocular CS, oscillatory potentials amplitude, b-wave amplitude on ffERG (152.3[45.4] vs 187.1[32.7]µV; P = 0.002), and PhNR amplitude (135.0[35.0] vs 156.3[34.1]µV; P = 0.025). There was no statistically significant difference in OCT measurements between groups. No correlation was found between statistically significant measurements and clinical data. CONCLUSIONS: Functional abnormalities on CS, ffERG, and PhNR can be detected in PD even when structural damages are not observed on OCT. PhNR represents a new potential biomarker in PD. Our findings indicate dysfunction of bipolar, amacrine, and retinal ganglion cells in PD, probably with a cellular dysfunction overcoming morphological damage.

Choroidal Thickness in Eyes with Band Atrophy of the Optic Nerve from Chiasmal Compression.

Background: The choroid is a vascular tissue that helps maintain retinal and prelaminar optic nerve head function. Choroidal thickness has been previously studied in diseases accompanied by retinal neural loss, but the relationship between the two sets of measurements is not clear. In eyes with temporal hemianopia as a result of chiasmal compression lesions (CCL), retinal neural loss tends to be greater in the nasal than the temporal hemiretina, a fact that may be useful in evaluating the effect of inner retinal layer loss on choroidal thickness. Purpose: To evaluate macular and peripapillary choroidal thickness on swept-source optical coherence tomography (SS-OCT) in eyes with temporal hemianopia as a result of chiasmal compression and in healthy controls. Methods: 33 eyes of 26 patients with band atrophy of the optic nerve and temporal visual field defects as a result of previously treated suprasellar tumors (CCL group) and 40 eyes of 21 healthy controls underwent SS-OCT scanning. The thickness of the peripapillary retinal nerve fiber layer (pRNFL), the peripapillary choroid (pChoroid), the macular RNFL (mRNFL), the macular ganglion cell layer (mGCL), and the macular choroid (mChoroid) was expressed globally and by sector (peripapillary quadrants and macular hemifield and quadrants). Ratios between macular nasal and temporal hemifield and quadrantic measurements were calculated using generalized estimated equation models, and the two groups were compared. Results: The pRNFL, mRNFL, and mGCC thicknesses were significantly smaller in the CCL group than in the control group (64.67 ± 10.53 µm, 29.68 ± 5.80 µm, and 80.60 ± 10.17 µm vs. 103.78 ± 12.23 µm, 39.89 ± 3.82 µm, and 105.51 ± 7.76 µm, respectively; p < 0.001). For the choroid, the only difference between the groups was increased macular nasal hemifield and superonasal quadrant thickness in CCL (222.47 ± 61.05 µm and 230.45 ± 58.59 µm in the CCL group, respectively vs. 190.68 ± 52.54 µm and 197.65 ± 54.80 µm in the control group, respectively; p < 0.05). The temporal/nasal ratios were significantly higher for the mRNFL and mGCC parameters and significantly lower for the mChoroid parameters in the CCL group, except for the superotemporal/superonasal quadrant ratio. Conclusions: The choroid does not thin after the inner retinal layer becomes damaged due to CCL and may even be thicker in some areas with corresponding severe retinal neural loss. While further studies are needed to interpret these findings, choroidal thinning is most likely not secondary to optic nerve disease-related inner retinal neural loss.

Bruch Membrane Opening Minimum Rim Width and Retinal Nerve Fiber Layer Helps Differentiate Compressive Optic Neuropathy From Glaucoma.

PURPOSE: To compare optical coherence tomography-measured Bruch membrane opening minimum rim width (MRW), peripapillary retinal nerve fiber layer (pRNFL) measurements, and MRW:pRNFL ratios in eyes with compressive optic neuropathy (CON) and glaucoma and controls, and evaluate the ability of these parameters to differentiate CON from glaucoma. DESIGN: Prospective, cross-sectional study. METHODS: Setting: Single-center tertiary hospital and outpatient clinic. PATIENT POPULATION: One hundred fifteen eyes of 77 participants, 34 with CON from chiasmal lesions, 21 with glaucoma, and 22 healthy controls. OBSERVATION PROCEDURES: Optical coherence tomography-measured MRW, pRNFL, and MRW:pRNFL ratios for each optic disc sector and global average. MAIN OUTCOME MEASURES: MRW, pRNFL, and MRW:pRNFL ratios compared using generalized estimated equations. Area under the receiver operating characteristic curve and positive and negative likelihood ratios were calculated. RESULTS: MRW and pRNFL measurements were significantly reduced in CON and glaucoma compared with controls. In glaucoma, MRW was thinner than in CON in the global, inferotemporal, superonasal, inferonasal, and vertical average measurements, but a significant overlap was observed in many parameters. MRW:pRNFL ratios increased the ability to discriminate between CON and glaucoma, as shown by the high area under the receiver operating characteristic curve, high positive likelihood ratios, and low negative likelihood ratios, especially in the nasal disc sector and the nasal and temporal average. CONCLUSIONS: MRW measurements alone cannot reliably distinguish CON from glaucoma, but the combination of MRW, pRNFL, and MRW:pRNFL ratios significantly improves accuracy. When comparing the 2 conditions, MRW:pRNFL ratios yielded higher area under the receiver operating characteristic curve and positive and negative likelihood ratios, suggesting this parameter may be helpful in clinical practice.

Unilateral papilledema and peripapillary polypoidal choroidal vasculopathy as the presenting manifestations of intracranial hypertension / Papiledema unilateral e vasculopatia polipoidal da coroide peripapilar como sinais de apresentação de hipertensão intracraniana

ABSTRACT We have reported here the case of a 54-year-old woman with intracranial hypertension that presented with the unique features of unilateral papilledema and peripapillary polypoidal choroidal vasculopathy. Our investigations lead to the diagnosis of idiopathic intracranial hypertension and an incidental small right frontal meningioma. The patient was accordingly treated with oral acetazolamide, followed by three consecutive monthly intravitreal injections of bevacizumab, which resulted in the inactivation of the polypoidal choroidal vasculopathy, marked reduction of lipid exudation, and complete absorption of the subretinal fluid. This case serves as the first documentation of polypoidal choroidal vasculopathy associated with papilledema. It also demonstrates that choroidal vascular abnormalities may occur even when optic disk edema is unilateral, which is an uncommon manifestation of increased intracranial pressure. Prompt recognition of such findings and its appropriate management are essential for adequate treatment and prevention of irreversible visual loss.

RESUMO Relatamos um caso de uma paciente de 54 anos com hipertensão intracraniana que apresentava achados atípicos de papiledema unilateral e vasculopatia polipoidal da coroide peripapilar. A investigação levou ao diagnóstico de hipertensão intracraniana idiopática e de um pequeno meningioma incidental. A paciente foi tratada com acetazolamida por via oral, seguida de três injeções intravítreas mensais de bevacizumabe, resultando em inatividade da vasculopatia polipoidal da coroide, redução da exsudação e completa absorção do líquido subretiniano. A apresentação deste caso serve para documentar pela primeira vez vasculopatia polipoidal da coroide associada a papiledema. Ele também demonstra que podem ocorrer anormalidades vasculares da coroide mesmo quando o edema do disco óptico é unilateral, uma manifestação incomum do aumento da pressão intracraniana. O reconhecimento imediato desses achados e seu manejo adequado são essenciais para o tratamento adequado e para prevenção da perda visual irreversível.

Sequence of focal choroidal excavation types in a patient with bilateral central serous chorioretinopathy / Sequência dos tipos de escavação focal de coroide em um paciente com coriorretinopatia serosa central bilateral

ABSTRACT A 39-year-old policeman complained of decreased bilateral central vision over the last two years. On examination, visual acuity was 20/40 and 20/400 in the right (OD) and left eye (OS), respectively, and fundoscopy revealed a bilateral hypopigmented macular lesion. Fluorescein and indocyanine green angiography demonstrated leakage and hyperintense spots, respectively, within the macular areas. At baseline, optical coherence tomography showed subretinal fluid in the OD and a conforming focal choroidal excavation in the OS. Focal choroidal excavation converted from conforming to nonconforming type at 4-month follow-up and then reversed to conforming type at 12-month follow-up, and was associated with incomplete retinal pigment epithelium and outer retina atrophy over the area of excavation. Pachyvessels were also evidenced in the choroid, without neovascularization. We report for the first time a case of focal choroidal excavation that progressed from conforming to nonconforming type and then reverted to its primary configuration (conforming type) in a patient with concurrent bilateral central serous chorioretinopathy.

RESUMO Um policial de 39 anos se queixava de diminuição bilateral da visão central nos últimos 2 anos. A acuidade visual era 20/40 e 20/400 no olho direito (OD) e esquerdo (OE) e a fundoscopia revelou lesão macular hipopigmentada bilateral. A angiografia fluoresceínica e com indocianina verde revelaram, respectivamente, vazamento do corante e áreas hiperintensas nas regiões maculares. A tomografia de coerência óptica evi denciou fluido sub-retiniano no OD e escavação focal de coroide do tipo conformacional no OE. Após 4 meses, a escavação focal de coroide mudou de conformacional para não conformacional e, aos 12 meses, reverteu para conformacional associado a atrofia incompleta do epitélio pigmentar da retina e da retina externa na região da escavação. Também foi evidenciado paquicoroide, sem neovascularização. Relatamos pela primeira vez uma escavação focal de coroide que evoluiu de conformacional para não conformacional e, em seguida, retornou à configuração primária (conformacional) em um paciente com coriorretinopatia serosa central bilateral.

Nodular anterior scleritis associated with Berger's disease.

A 45-year-old female patient presented with a complaint of right eye redness and pain for 7 days. She was under investigation for urinary abnormalities and reported a previous history of recurrent oral ulcers and ocular hyperemia in both eyes. Best-corrected visual acuity was 20/30 and 20/20 in the right and left eyes, respectively. Slit-lamp biomicroscopy of the ocular surface of the right eye revealed nasal scleral hyperemia that persisted after instillation of topical phenylephrine 10%, reinforcing the diagnosis of anterior scleritis. Renal biopsy showed immunoglobulin A immune complexes and confirmed the suspected diagnosis of Berger's disease. Maintenance immunosuppressive therapy with azathioprine following a 6-month induction of remission with cyclophosphamide was necessary after pulse therapy with methylprednisolone. Scleritis is usually related to systemic autoimmune diseases, such as rheumatoid arthritis, and polyangiitis. Herein, we describe a rare case of unilateral anterior scleritis associated with Berger's disease.

RESUMO Paciente de 45 anos, sexo feminino queixava-se de hiperemia e dor no olho direito há sete dias. Encontrava-se sob investigação de alterações urinárias e relatou história pregressa de úlceras orais e hiperemia ocular bilateral recorrentes. A acuidade visual corrigida era de 20/30 no olho direito e 20/20 no esquerdo. A biomicroscopia da superfície ocular do olho direito revelou intensa hiperemia escleral em região nasal que persistiu após a instilação de fenilefrina tópica a 10%, reforçando o diagnóstico clínico de esclerite anterior unilateral. A biópsia renal revelou a presença de imunocomplexos de IgA e confirmou a hipótese de doença de Berger. Uma terapia imunossupressora de manutenção com azatioprina após 6 meses de indução de remissão com ciclofosfamida foi necessária após pulsoterapia com metilprednisolona. A esclerite geralmente está relacionada a doenças autoimunes sistêmicas, como artrite reumatoide e poliangeite.

Angioid streaks and optic disc drusen in cherubism: a case report.

A 65-year-old female patient was referred to our hospital for evaluation for cataract surgery. Her past medical history included corrective jaw surgeries for facial deformities that developed during infancy and persisted through early adulthood. A complete ophthalmological examination revealed bilateral angioid streaks, drusen in both optic disc areas, and a subretinal neovascular membrane in the left macula. Genetic analysis revealed a mutation in the SH3BP2 gene compatible with the diagnosis of cherubism. Clinical and laboratory evaluation revealed no additional systemic disorders. Cherubism is a rare disease characterized by the development of painless fibro-osseous lesions in the jaws and the maxilla in early childhood. Ophthalmologic findings in this disease are primarily related to orbital bone involvement. This is the first report of AS and optic disc drusen in a patient diagnosed with cherubism. Our findings suggest that angioid streaks and optic disk drusen should be included in the differential diagnosis of ophthalmic disorders identified in patients with this genetic abnormality.

Unilateral acute posterior multifocal placoid pigment epitheliopathy in a patient with a strongly positive purified protein derivative test / Epiteliopatia pigmentar placóide multifocal posterior aguda unilateral na presença de reação forte positiva para o teste tuberculínico

ABSTRACT A 27-year-old man presented with a complaint of decreased visual acuity in the right eye. Best-corrected visual acuity was 20/60 in the right eye and 20/20 in the left eye. Right eye fundoscopy revealed mild vitritis, multifocal yellowish lesions, and macular serous retinal detachment. Left eye evaluation was normal. Acute posterior multifocal placoid pigment epitheliopathy was diagnosed in the right eye. Complementary exams revealed a strong reaction to the Mycobacterium tuberculosis purified protein derivative test, thus treatment for tuberculosis was initiated. Baseline fluorescein angiography of the right eye revealed early hypofluorescence and late staining of the lesions. Optical coherence tomography of the right eye demonstrated the accumulation of subretinal and intraretinal fluid associated with cystoid macular edema. During follow-up, the retinal fluid and cysts disappeared, which was followed by disorganization of foveal interdigitation and ellipsoid zones. This is the second described case of unilateral acute posterior multifocal placoid pigment epitheliopathy in a patient with a strong positive result to the M. tuberculosis purified protein derivative test.

RESUMO Um homem de 27 anos apresentou uma queixa de diminuição da acuidade visual no olho direito. A acuidade visual melhor corrigida foi 20/60 no olho direito e 20/20 no olho esquerdo. A fundoscopia do olho direito revelou vitreíte leve, lesões amareladas multifocais e descolamento seroso da retina em região macular. A avaliação do olho esquerdo foi normal. Epiteliopatia pigmentar placóide multifocal posterior aguda foi diagnosticada no olho direito. Os exames complementares revelaram forte reação ao teste do derivado proteico purificado Mycobacterium tuberculosis, iniciando terapia antibiótica contra tuberculose. A angiografia fluoresceínica basal do olho direito revelou hipofluorescência precoce e tardia das lesões. A tomografia de coerência óptica do olho direito demonstrou fluído sub- e intrarretiniano associado a edema macular cistóide. Durante o seguimento, os fluídos e cistos retinianos desapareceram, seguido da desorganização das zonas de interdigitação e elipsóide em região foveal. Este é o segundo caso descrito de epiteliopatia pigmentar placóide multifocal posterior aguda unilateral em um paciente com um forte resultado positivo para o teste tuberculínico.
