MULTIPLE INTRAVITREAL INJECTIONS DO NOT CAUSE ANTERIOR SCLERAL THINNING: An Ultrasound Biomicroscopy Study.

PURPOSE: To evaluate possible changes in anterior scleral thickness and structure and changes in the anterior segment in eyes receiving multiple intravitreal injections using ultrasound biomicroscopy imaging. METHODS: Prospective, interventional, nonrandomized, cross-sectional study. Both eyes from 33 patients previously treated at least by 15 intravitreal injections in one eye only for retinal diseases were included. Intravitreal injections were performed by ophthalmologists using an aseptic standardized procedure. Ultrasound biomicroscopy examination was performed in all eyes, and scleral thickness was measured at the pars plana in four quadrants. Anterior chamber depth and ciliary body size were measured. Scleral thickness in the study eye was compared with the fellow eye. Secondary outcome measures were 1) anterior chamber depth; 2) ciliary body size; 3) scleral qualitative changes in the study eye compared with the fellow eye and 4) risk factors for scleral thinning. RESULTS: There was no statistically significant difference in scleral thickness between the study and fellow eyes when comparing each quadrant between the two eyes (P = 0.86 superotemporal; P = 0.76 superonasal; P = 0.72 inferonasal; P = 0.55 inferotemporal). Scleral thickness was neither related to the number of injections nor to the duration of treatment in the treated eye. CONCLUSION: Multiple intravitreal injections do not impact scleral thickness in a clinical practice using different injection sites.

OPTICAL DENSITY RATIO OF THE SUBRETINAL FLUID IN CHOROIDAL MELANOMA AND METASTASIS.

PURPOSE: To investigate the optical density (OD) characteristics and clinical relevance of subretinal fluid in choroidal melanoma and choroidal metastasis. METHODS: Medical records of patients with choroidal melanoma and choroidal metastasis who underwent optical coherence tomography examinations at diagnosis before any intervention and whose optical coherence tomography scans showed sufficient subretinal fluid for sampling were reviewed. The highest quality B-scan containing subretinal fluid was analyzed. Optical density measurements obtained using ImageJ and optical density ratios (ODRs) were calculated as subretinal fluid OD divided by vitreous OD. Patient details and diagnosis were masked during measurements. Nonparametric tests for independent samples were used to detect differences in ODR between groups. RESULTS: Of the 39 cases of choroidal tumors that met the inclusion criteria, 14 were diagnosed as metastases and 25 as malignant melanoma. There were no significant differences between the groups in age, optical coherence tomography acquisition and parameters of quality, and vitreous OD. Optical density ratio values were significantly lower in metastases cases (mean 0.68, SD ±0.18) than in melanoma cases (0.95 ± 0.33, P = 0.006). Receiver operating characteristic curve analysis yielded an optimal cutoff of ODR = 0.771 (sensitivity = 78.6%, specificity = 72.0%). CONCLUSION: Optical density ratio can serve as an additional test to differentiate between choroidal melanoma and choroidal metastases.

Subretinal Fluid Optical Density and Spectral-Domain Optical Coherence Tomography Characteristics for the Diagnosis of Circumscribed Choroidal Hemangioma.

PURPOSE: To investigate spectral domain-optical coherence tomography (SD-OCT) features of untreated circumscribed choroidal hemangioma (CCH), and the optical density (OD) of the associated subretinal fluid (SRF). PROCEDURES: This international retrospective multicenter study conducted at 5 tertiary retina referral centers included 34 patients with symptomatic CCH imaged on SD-OCT. CCH surface, size, and overlying retinal changes and OD ratio (ODR) were evaluated. RESULTS: The mean ODR of the SRF was 0.808 ± 0.287. Tumor base measured on ultrasound correlated significantly with the ODR (p = 0.012). ODR values in cases of CCH were similar to those of choroidal metastasis, but significantly lower than those of choroidal melanoma (p = 0.006). Thirty-two out of 34 cases (94%) presented with a regular smooth choroidal surface. OCT demonstrated SRF overlying the CCH in 29 eyes (85%). The presence of SRF correlated significantly with a larger basal tumor diameter (p = 0.035). OCT displayed sub- and intraretinal hyperreflective foci, correlating with both larger maximal retinal thickness overlying the tumor (p = 0.031) and the amount of SRF (p = 0.016) in 29 eyes (85%). CONCLUSION: CCH displays typical findings on SD-OCT. ODR is a new important tool in the differential diagnosis of choroidal tumors and should be considered for enhancing the accuracy of diagnosing CCH. This benefit is especially relevant for cases in which the presentation of CCH is atypical.

Retina and Nerve Fiber Layer Thickness in Eyes with Thyroid-Associated Ophthalmopathy.

BACKGROUND: Thyroid-associated ophthalmopathy (TAO) is an inflammatory disease that affects the thyroid gland and the eye orbit. Of patients with TAO, 3%-5% have severe sight-threatening disease due to optic neuropathy Optical coherence tomography (OCT), the non-invasive imaging technology that yields high-resolution cross-sectional images of the retina, provides qualitative and quantitative data on the retina. OBJECTIVES: To apply this technique to quantitatively assess retinal nerve fiber layer (RNFL) and macular ring thicknesses in healthy subjects and in patients with TAO to determine their relationship to the severity of the orbital disease. METHODS: All patients in the ophthalmology clinic who were diagnosed with TAO and underwent OCT imaging as part of their ocular examination comprised the study group, and healthy patients who volunteered to undergo OCT examination served as controls. Results of the complete ophthalmologic examination and OCT findings were collected from medical files, including the thickness of the RNFL and the macula. RESULTS: The study comprised 21 patients and 41 healthy controls. TAO patients exhibited RNFL thickening and inner macula thinning compared to healthy subjects. Mean RNFL thickness was correlated with the severity of the orbital disease. CONCLUSIONS: The OCT findings suggest that the retina is involved in TAO, probably as early as the subclinical stage. This highlights the ability of OCT to identify retinal changes earlier and far more accurately than is detected today, enabling earlier diagnosis and more timely treatment to prevent severe visual sequelae.

Bevacizumab treatment of macular edema in CRVO and BRVO: long-term follow-up. (BERVOLT study: Bevacizumab for RVO long-term follow-up).

PURPOSE: To assess the efficacy and safety of intraocular injections of bevacizumab in patients with macular edema (ME) following branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). METHODS: Retrospective, non-comparative case series. Patients ≥18 years of age with ME secondary to BRVO or CRVO who received a minimum of one intravitreal injection of bevacizumab with a follow-up >3 months were included. Primary endpoints were mean change in best corrected visual acuity (BCVA) from baseline to 12 and 24 months, and mean change in central macular thickness (CMT) after 3 injections. Secondary endpoints were mean change in BCVA and CMT from baseline to end of follow-up, number of injections, and ocular adverse events. RESULTS: Eighty-seven eyes with BRVO and 65 eyes with CRVO were included. Mean follow-up time was 24.4 and 26.1 months in the BRVO and CRVO groups, respectively. The mean change in BCVA was 0.25 LogMAR in the BRVO group and -0.118 LogMAR in the CRVO group. CONCLUSION: Visual acuity outcomes in the CRVO group were poorer, especially in patients with low baseline BCVA.

Comparison of retinal detachment surgery outcome among patients undergoing pars plana vitrectomy with and without relaxing retinotomy.

The purpose of this four year retrospective study was to compare the anatomical and functional outcomes of complicated retinal detachment (RD) surgery by pars plana vitrectomy (PPV) with and without retinotomy. The main outcome measures were primary anatomical success (defined as retinal re-attachment at the final follow-up after a single operation, with or without silicone in situ), final anatomical success, final best-corrected visual acuity (BCVA) and postoperative complications. Baseline characteristics did not differ between the groups, although there was a borderline significant trend for the retinotomy group to be associated with worse pre-surgical ocular pathology. With a mean follow-up of 18 (± 7.8) months, primary anatomical success was achieved in 76.7% (33 of 43) of the retinotomy group eyes vs. 67.8% (40 of 59) of the eyes in the group without retinotomy. Final anatomical success rates for the retinotomy group and no retinotomy group were 100 and 93.2% respectively. The final BCVA was 1.57 LogMAR with retinotomy and 1.38 without retinotomy, an improvement in both groups. The incidence of postoperative complications was similar in the two groups, while the frequency of macular holes was higher in the retinotomy group. A similar degree of improvement in BCVA following both surgeries indicates their similar efficacy and justifies their performance even in complicated eyes in order to improve the patients' quality of life. With neither approach superior to the other, the choice of method should be left to the surgeon.

The prevalence of retinal and optical coherence tomography findings in preeclamptic women.

PURPOSE: To evaluate retinal and optical coherence tomography findings and establish their prevalence in preeclamptic women. METHODS: Twenty-seven preeclamptic women who underwent clinical examinations with both slit-lamp biomicroscopy and optical coherence tomography were prospectively studied. RESULTS: Three of the 4 women (14.8%) identified by clinical examinations as having retinal findings related to preeclampsia had visual disturbances. Optical coherence tomography revealed retinal pathology in 2 women (7.4%) consisting of retinal edema, subretinal fluid, photoreceptors irregularities, and lesions at the retinal pigment epithelium level (Elschnig spots). The mean retinal nerve fiber layer thickness was significantly higher in women with pathologic funduscopic findings (P = 0.009) than in women with normal eye examinations. All women with ocular findings had severe preeclampsia and higher systolic blood pressure than women without ocular findings (P = 0.03). CONCLUSION: The prevalence of retinal involvement is high in severe preeclampsia and low in asymptomatic preeclampsia. Preeclamptic women diagnosed as having ocular involvement should be evaluated and monitored by optical coherence tomography, provided that their systemic condition allows it. Findings of retinal nerve fiber layer thickening in these women may indicate occult central nervous system involvement.

Visual acuity outcomes in eyes with flat corneas after PRK.

PURPOSE: To evaluate the impact of corneal curvatures less than 35 diopters (D) after photorefractive keratectomy (PRK) on visual acuity outcomes. METHODS: Visual acuity outcomes of 5,410 eyes that underwent PRK from January 2006 to November 2010 were retrospectively analyzed for the impact of postoperative corneal curvatures on visual outcomes. All procedures were performed on a single platform (Allegretto 200Hz excimer laser; Alcon Laboratories, Inc., Irvine, CA). Main outcome measures were postoperative corrected distance visual acuity (CDVA) and loss of CDVA. RESULTS: Corneas with a measured or a calculated postoperative flat meridian less than 35 D and those with a measured postoperative steep meridian less than 35 D had worse postoperative CDVA than corneas with meridians of either 35 D or more (P ≤ .021). However, the preoperative CDVA was worse in the flatter curvatures in all comparisons performed (P ≤ .024). Consequently, the measured or calculated meridian curvature had no effect on CDVA loss (P ≥ .074). CONCLUSION: Postoperative corneal keratometry values (flat and steep meridians) less than 35 D did not have a predictive effect on the risk of losing visual acuity following myopic PRK performed on the Allegretto 200Hz excimer laser.

Contribution of T cell subset analysis in induced sputum in diagnosing ocular sarcoidosis.

OBJECTIVE: The aim of this study was to establish a correlation between the diagnosis of ocular sarcoidosis and the presence of an elevated CD4/CD8 ratio in the induced sputum(IS) of patients with uveitis and no other systemic symptoms. METHODS: This retrospective chart review study included all newly diagnosed uveitis patients treated between 1998-2006. IS examinations and determination of angiotensin-converting enzyme (ACE) levels were carried out. A CD4/CD8 ratio > 2.5 and an ACE level > 145 Cd/ml/min were considered abnormal. The etiology of uveitis was retrieved from the medical records. RESULTS: Twenty males and 26 females (mean age 47 +/- 16.1 years) were enrolled. The CD4/CD8 ratio was elevated in 26 (56.5%) patients, and five (10.9%) were diagnosed as having sarcoidosis by the end of follow-up. The sensitivity and specificity of the T lymphocytes CD4/CD8 ratio in diagnosing sarcoidosis were 100% and 48.8%, respectively. CD4/CD8 ratios were not significantly different between the sarcoid and non-sarcoid groups (p > 0.05), but the former tended to have higher levels (p = 0.0991). The mean ACE level of the sarcoid patients was significantly higher than that of the non-sarcoid patients (p < 0.001). CONCLUSION: CD4/CD8 lymphocytes ratios obtained by IS were sensitive in uveitis patients with concomitant sarcoidosis, suggesting that analysis of T cells subsets in IS may rule out an etiology of sarcoidosis in newly diagnosed uveitis patients.

Color Doppler imaging of eyes with persistent fetal vasculature.

BACKGROUND: Eyes with persistent fetal vasculature (PFV) may be mistaken for retinoblastoma and provide a diagnostic challenge. OBJECTIVE: This study aimed to evaluate the role of color Doppler imaging (CDI) in children with persistent fetal vasculature. MATERIALS AND METHODS: Eyes with a diagnosis of PFV were evaluated by CDI. RESULTS: Twenty eyes of 17 children were included. All had a confirmed diagnosis of PFV based on one or more of the following: clinical findings on funduscopy, characteristic findings on imaging modalities (ophthalmic gray-scale US, CT and/or MRI), typical findings observed intraoperatively, and histopathological analysis (after enucleation in one case). Blood flow within the PFV was demonstrated in 19 eyes in this series. CONCLUSION: CDI is a noninvasive diagnostic tool that may add useful information on the presence of blood flow within the PFV and may substantiate the diagnosis of PFV in cases of uncertainty.

Optical coherence tomography characteristics of eyes with acute anterior uveitis.

BACKGROUND: Acute, as opposed to chronic, anterior uveitis is rarely associated with macular or optic nerve edema. Nevertheless, mild changes may not be visible on examination. OBJECTIVE: To implement non-invasive ocular coherence tomography (OCT) for obtaining quantitative and qualitative data in the assessment of changes in macular morphology and peripapillary retinal nerve fiber layers in eyes with acute anterior uveitis. METHODS: This retrospective case-control study was conducted in patients with unilateral acute anterior uveitis lasting for up to one month. Patients with evidence of other ocular disease or who had undergone intraocular surgery were excluded. We reviewed the charts of 14 consecutive patients who were diagnosed with acute unilateral anterior uveitis between 2007 and 2008 at the Tel Aviv Medical Center. Data on demographic details, ophthalmic examination, macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness (as demonstrated by OCT) were retrieved. Retinal and RNFL thickness was compared between the healthy fellow eye (control) and the uveitic eye in the central and four perifoveal quadrant regions, and RNFL thickness was compared in the mean and four quadrant values by Student's t-test. RESULTS: We evaluated 28 eyes of7 males and 7 females (mean age 37.7 years, range 20-65). The diagnoses were: idiopathic in five patients, ankylosing spondylitis in five, Crohn's disease in one patient and reactive arthritis in one. Nine patients were HLA-B27 positive. The retina and the peripapillary NFL in each area were thicker in the uveitic eyes compared to the controls. The difference was statistically significant. There was no correlation between the differences in OCT values and patients' demographic characteristics. CONCLUSIONS: OCT demonstrated that eyes with acute anterior uveitis had thicker maculae and thicker peripapillary RNFL than controls. This finding suggests that even milder anterior uveitis may be associated with some degree of posterior segment manifestations.

Peripapillary hyperreflective ovoid mass-like structures-a novel entity as frequent cause of pseudopapilloedema in children.

BACKGROUND: Optic nerve head drusen (ONHD) are considered the most common cause for pseudopapilloedema in children. We aimed to investigate and further characterize a new type of optic nerve head lesion on enhanced depth imaging optical coherence tomography (EDI-OCT) named peripapillary hyperreflective ovoid mass-like structures (PHOMS), and ONHD in asymptomatic children with pseudopapilloedema. METHODS: Retrospective cohort study including 64 eyes from 32 patients with pseudopapilloedema due to PHOMS and/or ONHD. Mean age was 9.0 ± 3.1 years. PHOMS and ONHD were identified and classified on EDI-OCT and infrared images. Ultrasound images were classified for the presence of hyperechogenic structures of the optic nerve head. RESULTS: On EDI-OCT, PHOMS were detected in 63 out of 64 eyes (98.4%). In 60 eyes (93.8%), small hyperreflective foci inside the PHOMS were present. In all cases, we identified a new ring sign visible on infrared images, corresponding clearly to the edge of the PHOMS as seen on EDI-OCT. On ultrasound, we describe a new feature of PHOMS appearing as small hyperechogenic structures without posterior shadowing. In 13 eyes (20.3%), ONHD were present on EDI-OCT and ultrasound. CONCLUSION: This is the first study showing that PHOMS are the most common cause for pseudopapilloedema in children. PHOMS is a new entity of optic nerve head lesions. It might be a precursor of buried optic nerve head drusen, which can lead to visual field defects, haemorrhages and CNV. This study offers new tools to identify and follow-up these lesions early in childhood using EDI-OCT.

Accuracy of the Ultrasound Biomicroscopy Bag/Balloon Technique in Locating Horizontal Extraocular Muscle Insertions Before and After Strabismus Surgery.

PURPOSE: To investigate the accuracy of high frequency ultrasound biomicroscopy using the bag/balloon technique to locate recti muscle insertions before and after strabismus surgery. METHODS: This was a prospective masked study. The distance from the limbus to horizontal recti muscle insertions was measured by caliper intraoperatively and ultrasound biomicroscopy preoperatively and during follow-up. Accuracy was defined as the difference between ultrasound biomicroscopy and caliper measurements. RESULTS: Thirty-nine muscles (19 medial rectus and 20 lateral rectus) of 22 patients were included. The mean age of the patients was 34.7 ± 15.5 years (range: 18 to 78 years). Follow-up measurements were available for 25 muscles: 12 muscles were recessed and 13 were resected/advanced. Twelve of the included muscles underwent prior surgery. There was a strong correlation between preoperative mean ultrasound biomicroscopy and caliper measurements (P < .001, rp = 0.872) without significant difference between the accuracy of identification of medial rectus and lateral rectus muscles (P = .116 and .377, respectively). On average, postoperative ultrasound biomicroscopy measurements of recessed muscles were 1.15 mm greater than caliper measurements at the end of surgery (P = .003), whereas the mean difference in the resected muscles was not statistically significant (-0.07 mm, P > .999). Overall, in 16 of 25 muscles (64%), the differences between the postoperative measurements and the end of surgery measurements were less than 1 mm. There was no correlation between the accuracy and the time of ultrasound biomicroscopy after surgery (P = .516). CONCLUSIONS: The ultrasound biomicroscopy bag/balloon technique is an accurate and reliable method of locating recti muscle insertions before and after strabismus surgery. Ultrasound biomicroscopy may assist strabismologists in planning repeated operations. [J Pediatr Ophthalmol Strabismus. 2020;57(1):12-20.].

Diagnosis of Peripheral Retinoschisis Using Ultrasound Biomicroscopy.

BACKGROUND AND OBJECTIVE: Retinal imaging can help differentiate retinoschisis (RS) from retinal detachment (RD). This study describes new sonographic features of RS using ultrasound biomicroscopy (UBM) and evaluates their diagnostic value. PATIENTS AND METHODS: Medical records of subjects diagnosed with RS and RD who underwent imaging prior to intervention were reviewed. Images were evaluated for detachment shape ultrasound (US) B-mode, as well as presence of intraretinal pillars, retinal layers split, and intraretinal cysts on UBM. RESULTS: Of 48 eyes from 48 patients in the study, 25 were diagnosed as RS and 23 as RD. "Retinal layers split" was the most common UBM finding in the RS group (72%), followed by intraretinal pillars (64%) and intraretinal cysts (36%). No RD case exhibited these findings (P < .001). CONCLUSIONS: UBM might assist in difficult cases to differentiate between RS and RD by detection of the unique sonographic features of RS described herein.

Aminobisphosphonate-associated orbital and ocular inflammatory disease.

PURPOSE: Aminobisphosphonates may cause orbital/ocular inflammation. Awareness of the clinical presentation and disease course is crucial. The purpose of this study was to analyse demographics, clinical presentation, disease course and treatment of aminobisphosphonate-associated orbital/ocular inflammation in a large series of patients. METHODS: A retrospective study of patients with aminobisphosphonate-associated orbital/ocular inflammation and a literature review to differentiate disease presentation and course between various aminobisphosphonates. RESULTS: Eight patients from our institution (6 women and 2 men, median age 62 years) were included. The used drugs were zoledronate, alendronate and risedronate. The most common clinical presentation was conjunctival hyperaemia/chemosis. Scleritis was the most common manifestation, followed by diffuse orbital inflammation and anterior uveitis. Ultrasound aided in diagnosis in all our patients. The aminobisphosphonate was halted in all patients, and some patients had anti-inflammatory treatment. Literature review included 68 patients (83 eyes), of them the most abundant drugs causing orbital/ocular inflammation were pamidronate (38 eyes) and zoledronate (35 eyes). Overall, among 76 patients, all drugs induced orbital disease, while uveitis was induced mostly by zoledronate and pamidronate, less by alendronate and not found among risedronate users. Time interval from drug administration to symptoms was hours to 28 days. Resolution was achieved in all patients, after 1-60 days from disease presentation, and the longer resolution period was found among alendronate users. CONCLUSION: Orbital/ocular inflammation was mostly caused by intravenous aminobisphosphonates. Uveitis was not induced by risedronate. The putative aminobisphosphonate should be halted at the onset of orbital/ocular involvement and prognosis is favourable.

The role of posterior vitreous detachment on the efficacy of anti-vascular endothelial growth factor intravitreal injection for treatment of neovascular age-related macular degeneration.

PURPOSE: A prospective cohort study investigating the effect of posterior vitreous detachment (PVD) on the efficacy of intravitreal bevacizumab for exudative age-related macular degeneration (AMD), in view of evidence that the vitreoretinal interface impacts the severity of the disease. METHODS: Treatment-naïve AMD eyes with (+) complete PVD and without (-) PVD on ultrasonography received three monthly and then pro re nata bevacizumab injections. Best-corrected visual acuity (BCVA) on Snellen charts and optical coherence tomography (OCT) findings were recorded for 12 months. Secondary analysis included PVD definition and group allocation according to OCT baseline scan. RESULTS: Forty-one eyes of 34 patients met the inclusion criteria. At 12 months, median BCVA improved by 0.12 logMAR in the PVD+ group [interquartile range (IQR) -0.52, 0.03, P = 0.140] and remained the same in the PVD- group (IQR -0.12, 0.15, P = 0.643). Median central retinal thickness improved by 43.5 µm and 43 µm in the PVD+ (IQR -143, 3, P = 0.016) and PVD- group (IQR -90, -14, P = 0.008), respectively. All parameters were similar in the two groups at final follow up (P > 0.05). The secondary analysis included 32 eyes of 26 patients and showed no significant differences between the groups at the 12 months endpoint (P > 0.05). CONCLUSION: Our findings show no significant impact of PVD as assessed by ultrasound or by OCT on visual and anatomical outcomes in exudative AMD treated with bevacizumab.

Adipose-Derived Mesenchymal Stem Cells Migrate and Rescue RPE in the Setting of Oxidative Stress.

Oxidative stress leads to the degeneration of retinal pigment epithelial (RPE) and photoreceptor cells. We evaluated the potential of adipose-derived mesenchymal stem cells (ASCs) as a therapeutic tool by studying the migration capacity of ASCs in vitro and their protective effect against RPE cell death under oxidative stress in vitro and in vivo. ASCs exhibited enhanced migration when exposed to conditioned medium of oxidative stressed RPE cells obtained by hydrogen peroxide. Migration-related axis SDF-1/CXCR4 was studied, and upregulation of SDF-1 in stressed RPE and of CXCR4 in ASCs was detected. Moreover, ASCs' conditioned medium prevented H2O2-induced cell death of RPE cells. Early passage ASCs had high expression level of HGF, low VEGF levels, and unmodulated IL-1ß levels, compared to late passage ASCs. Thus, early passage ASCs show the potential to migrate towards damaged RPE cells and protect them in a paracrine manner from cell death induced by oxidative stress. In vivo, mice received systemic injection of NaIO3, and 72 h later, ASCs were transplanted in the subretinal space. Seven days after ASC transplantation, the eyes were enucleated fixed and frozen for immunohistochemical analysis. Under such conditions, ASC-treated mice showed preservation of nuclear layers in the outer nuclear layer and stronger staining of RPE and photoreceptor layer, compared to PBS-treated mice. Taken together, our results indicate that ASCs are able to home in on damaged RPE cells and protect against damage to the RPE and PR layers caused by oxidative stress. These data imply the potential that ASCs have in regenerating RPE under oxidative stress, providing the basis for a therapeutic approach to retinal degeneration diseases related to oxidative stress that could help save the eyesight of millions of people worldwide.

CHOROIDAL EFFUSION AS AN OCULAR MANIFESTATION OF IMMUNOGLOBULIN G4-RELATED DISEASE.

PURPOSE: To report a unique ocular manifestation of immunoglobulin G4-related disease (IgG4-RD) as choroidal effusion. METHODS: Case report. RESULTS: An 81-year-old man presented with clinical manifestations of choroidal effusion, confirmed by fluorescein angiography, ophthalmic ultrasound (posterior segment), high-frequency ultrasound biomicroscopy, Heidelberg Spectralis spectral domain optical coherence tomography, and enhanced depth imaging spectral domain optical coherence tomography. Systemic multi-organ findings included chronic pancreatitis, irregularity of the intrahepatic bile ducts, lymphadenopathy, aortitis, fibrotic changes of the lungs, hypophysitis, and sialadenitis. Extensive workup revealed elevated IgG4 serum levels, and lymph nodes biopsy showed reactive pattern with polyclonal IgG4 positive plasma cells. These findings were compatible with IgG4-related disease. Treatment with oral corticosteroids resulted in complete resolution of the choroidal effusion. CONCLUSION: Choroidal effusion may be an ocular manifestation of IgG4-related disease. Oral corticosteroids is an effective treatment. Ophthalmologists should be aware of this possible finding.
