RESUMO

Atopic dermatitis is usually associated with various ocular complications. We report a 21-year-old Chinese male who presented to our ophthalmology clinic with bilateral retinal detachment and cataracts. The patient had a clear medical history of atopic dermatitis, which had been diagnosed eight years earlier and had been treated with loratadine and pimecrolimus. Cataract surgery was performed for both eyes, combined with scleral buckling for the right eye and pars plana vitrectomy for the left eye. During postoperative follow-up, fundus fluorescein angiography showed retinal vasculitis in both eyes and macular edema in the left eye, which coincided with an exacerbation of atopic dermatitis. Macular edema improved after four months of regular dupilumab treatment in the dermatology department. The ocular condition remained stable three years postoperatively.

RESUMO

PURPOSE: To evaluate the relationship of serum vascular endothelial growth factor (VEGF) levels and ocular manifestations in Chinese patients with POEMS syndrome. METHODS: This is a prospective study. Forty-one treatment-naive patients were enrolled from April 2014 to November 2014. Among the 41 patients, 40 had complete ocular examination, spectral domain optical coherence tomography scan, and serum VEGF measurement before treatment and every 3-month interval after lenalidomide and dexamethasone treatment. RESULTS: Twenty-seven (67.5%) patients had optic disk edema (ODE) at baseline. Retinal manifestations included retinal hemorrhage, subretinal fluid, macular edema, and cotton wool spot. The difference in mean serum VEGF concentrations between patients with and without ODE was significant (P = 0.017). Among patients with ODE, there was a significant positive correlation between mean serum VEGF levels and the binocular mean retinal nerve fiber layer thickness (P = 0.008), as well as mean peripapillary retinal thickness (P = 0.020) before treatment. After 3 months to 17 months treatment, mean serum VEGF concentrations decreased significantly (P < 0.001). Mean retinal nerve fiber layer thickness and mean peripapillary retinal thickness decreased significantly (P < 0.001). The remission rate of ODE was 87.5%, and complete remission rate was 58.3%. CONCLUSION: The ODE is a common manifestation in POEMS syndrome, and raised VEGF might explain the development and mechanism. Systemic treatment could lead to decrease in serum VEGF levels accompanied by regression of ODE.

RESUMO

Making accurate and timely diagnosis is often challenging when patients with a systemic disease first present with ocular manifestations. The possibility that vasculitis associated with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) can be misdiagnosed as cysticercosis has not been discussed in the literatures.

RESUMO

PURPOSE: To develop diagnostic recommendations for diffuse large B-cell vitreoretinal lymphoma (VRL) in Chinese patients. METHODS: Retrospective observational case series. Seventy-three eyes of 40 VRL patients and 8 control patients were analyzed. Eighteen patients from Beijing Tongren Hospital and 46 patients from literature were involved as validations. RESULTS: Diagnostic methods included (1) typical clinical manifestations; (2) vitreous cytology; (3) immunohistochemical examination of vitreous or choroid/retina; (4) aqueous humor or vitreous cytokine; (5) vitreous cell gene rearrangement; (6) vitreous flow cytometry. If patients meet (1)+(2)+(3), or if they meet (1), and two of (4), (5), (6) are positive, they can be diagnosed as VRL. The sensitivity and specificity values for accurate diagnosis were 0.975 and 1.00. One hundred percent eyes from Beijing Tongren Hospital and 92.7% eyes from literature can be diagnosed. CONCLUSION: We developed diagnostic recommendations for diffuse large B-cell VRL through vitreous cytology combined with multiple auxiliary examinations.

RESUMO

OBJECTIVE: To provide novel spectral domain optical coherence tomography (SD OCT) findings of Vogt-Koyanagi-Harada (VKH) disease as well as new insights into the pathogenesis of this disease. METHODS: Detailed SD OCT and fluorescein angiography (FA) findings of 18 consecutive VKH patients (11 women and 7 men) from December 2007 to April 2009 who were in acute uveitic stage at presentation were reviewed. All the patients had been followed up for at least 6 months with reevaluation(s) of SD OCT performed in 10 patients. RESULTS: Intraretinal cysts were found to be located in various layers of the outer retina. In addition to the photoreceptor layer, they could also be found between the outer plexiform layer and the outer nuclear layer, or spanning the external limiting membrane. On FA, intraretinal cysts could be hypofluorescent, normofluorescent, or hyperfluorescent. Some intraretinal cysts had a characteristic FA pattern, in which a small round hypofluorescent area was surrounded by a ring of hyperfluorescence (donut-shaped dye pooling). Subretinal fibrinoid deposit appeared in acute uveitic stage in two severe VKH patients and seemed to develop from subretinal exudates and evolved into typical subretinal fibrosis. Gradual transfiguration/migration and progressive proliferation/pigmentation of the subretinal fibrinoid deposit/subretinal fibrosis was observed in one patient. CONCLUSIONS: Intraretinal cysts could form in various layers of the outer retina and may result from extension of choroidal inflammation. Subretinal fibrosis may develop from subretinal exudates in VKH patients and may cause substantial visual impairment.

RESUMO

OBJECTIVE: To evaluate the fundus manifestation and treatment of Takayasu's arteritis. METHODS: Retrospective case series was taken to study the clinical data of 15 patients (30 eyes) diagnosed with Takayasu's arteritis at Peking Union Medical College Hospital from 1992 to 2010. Examinations included visual acuity, slit-lamp, fundus, fundus fluorescein angiography (FFA), large vascular ultrasound, digital subtraction angiography (DSA), erythrocyte sedimentation rate (ESR) and reactive protein C (CRP). All patients were given systemic corticosteroids, immunosuppressive agents and anticoagulants. Three patients (4 eyes) received retinal photocoagulation, and 1 patient (1 eye) received vitrectomy combined with silicone oil tamponade. RESULTS: Fifteen cases aged 13 - 49 years [mean (33.6 ± 11.1) years] were enrolled, including 2 male and 13 female patients. Two patients recognized by initial presentation of impaired vision prior to the diagnosis of Takayasu's arteritis. Visual acuity: light perception -0.05, 6 eyes; 0.1 - 0.5, 4 eyes; 0.6 - 1.0, 5 eyes; and above 1.0, 15 eyes. The fundus examination revealed chronic ischemic retinopathy in 16 eyes characterized by microaneurysms, cotton-wool spots and peripapillary arteriovenous anastomosis, and complicated by vitreous hemorrhage, retinal detachment and proliferative retinopathy at the late stage. There was hypertensive retinopathy in 14 eyes with features of narrow retinal artery, arteriovenous crossing signs and retinal hemorrhage. FFA showed prolonged arm-to-retina circulation time and retinal circulation time, microaneurysms and neovasculature. Six cases were classified as brachiocephalic arteritis, and 9 patients belonged to extensive arteritis. ESR increased in 9 patients and CRP elevated in 5 patients. Capillary non-perfusion areas in 4 eyes subsided after retinal photocoagulation, and retina reattached in 1 eye after vitrectomy with visual acuity improved from light perception to count finger. CONCLUSIONS: Fundus manifestation of Takayasu's arteritis is usually characterized by chronic ischemic retinopathy and hypertensive retinopathy, and complications such as vitreous hemorrhage, retinal detachment and proliferative retinopathy occur at advanced stage. The first symptom in some patients can be impaired vision. The prognosis could be improved if ophthalmologists know fundus characteristics of Takayasu's arteritis and give timely and correct diagnosis and treatment.

RESUMO

BACKGROUND: Apnea caused by retrobulbar anesthesia is a very rare but severe complication during ophthalmic surgery. CASE SUMMARY: We report a rare case of apnea caused by retrobulbar anesthesia, and emergency resuscitation was used. A 74-year-old female patient was diagnosed with rhegmatogenous retinal detachment in the right eye and planned to undergo vitrectomy under retrobulbar anesthesia. After the retrobulbar anesthesia in her right eye, she became unconscious and apneic. It was suggested that she had developed brainstem anesthesia. Assisted ventilation was initiated. Atropine 0.5 mg, epinephrine 1 mg, ephedrine 30 mg, and lipid emulsion were given. Five minutes later, her consciousness and breathing gradually returned, but with uncertain light perception in her right eye. Alprostadil 20 µg was given, and after 2 h her visual acuity resumed to the preoperative level. CONCLUSION: Brainstem anesthesia is a serious complication secondary to retrobulbar anesthesia. Medical staff should pay attention to the identification of brainstem anesthesia and be familiar with the emergency treatment for this complication.

RESUMO

Mammalian target of rapamycin (mTOR) inhibitors (sirolimus or everolimus) have been demonstrated effective in reducing the size of tuberous sclerosis complex (TSC)-associated retinal astrocytic hamartoma (RAH) in short term. To investigate the long-term efficacy and safety of sirolimus on TSC-associated RAH, 13 TSC-associated RAH patients (59 RAH lesions) who received sirolimus therapy for at least 2 years were retrospectively enrolled in this study. Changes in the maximal thickness (MT) of RAH on optical coherence tomography and the longest base diameter (LBD) of RAH on color fundus photography were assessed. The results showed that for a mean follow-up of 39 months, sirolimus was associated with a mean reduction of 14.6% in MT and 6.8% in LBD of RAHs. The main impacts of sirolimus occurred within the first 6-12 months, with 14.8% reduction in MT and 4.7% reduction in LBD. Mouth ulceration (10 [76.9%]) and acne (9 [69.2%]) were the most common adverse events. These follow-up data support the long-term use of sirolimus in TSC-associated RAH patients, and persistent use of sirolimus possibly prevents tumor regrowth.

RESUMO

OBJECTIVE: To determine the prevalence and risk factors of atherosclerotic lesions in retinal arteries of an urban population undergoing routine physical examinations. METHODS: Demographic and clinical information of subjects participating in annual routine physical examinations at Peking Union Medical Center from January to October of 2010 were collected and summarized. Univariate and multivariate Logistic regression analyses were conducted to evaluate the demographic and clinical factors associated with retinal arterial atherosclerosis. RESULTS: Among a total of 17 886 non-diabetic adults evaluated during the study period, retinal arterial atherosclerosis was diagnosed in 1721 (9.6%). There were predominantly grade 1 (88%) and grade 2 (11%) lesions. Prevalence of retinal arterial atherosclerosis increased with age. And traditional risk factors for cardiovascular diseases included overweight or obesity, hypertension, dyslipidemia and elevated fasting serum glucose. In a multivariate Logistic regression model, advanced age, male gender, obesity or overweight, hypertension and dyslipidemia were independently associated with a higher risk of retinal arterial atherosclerosis. Hypertension was prevalent in subjects above 40 years old while overweight or obesity had a high prevalence in all age groups. CONCLUSION: Retinal arterial atherosclerosis is common in this urban population. And aging, overweight/obesity and hypertension are the dominant risk factors. Routine physical examination is valuable for both the prevention and an early diagnosis of this disease.

RESUMO

OBJECTIVE: To evaluate the correlation between retinal artery atherosclerosis and renal dysfunction and compare their risk factors in an urban population of Beijing. METHODS: The non-diabetic adults > 40 years old undergoing annual physical examinations during June 2010 and February 2011 at one medical center were evaluated. Pearson correlation coefficient was calculated between retinal artery atherosclerosis and renal dysfunction. The analyses of multivariate Logistic regression were performed to compare the risk factors of these two diseases. RESULTS: Among 10 191 subjects included, retinal artery atherosclerosis was diagnosed in 1287 (12.6%) and renal dysfunction in 434 (4.3%). And 1.0% of subjects had both two diseases versus 12.2% with retinal artery atherosclerosis alone and 3.3% with renal dysfunction alone. Correlation coefficient was low between two diseases (r = 0.21; P < 0.01). According to the analyses of multivariate Logistic regression, the strongest predictors of retinal artery atherosclerosis were obesity (OR = 2.5, 95%CI 2.0 - 3.2) and hypertension (OR = 2.2, 95%CI 2.0 - 2.6) while advanced age (OR = 3.1, 95%CI 2.8 - 3.5 per 10 year increment) was the strongest factor for renal dysfunction. CONCLUSION: The low-level correlation and different risk factor profiles between retinal artery atherosclerosis and renal dysfunction indicate different pathogenic mechanisms of two diseases and suggest different preventive strategies.

RESUMO

OBJECTIVE: To evaluate the findings of spectral domain optical coherence tomography (SD-OCT) in patients with idiopathic macular hole (IMH). METHODS: It was a retrospective case series study. Pre- and post-operative data from patients with IMH during 14 months were analyzed retrospectively. The main outcome data included logarithm of the minimal angle of resolution (logMAR) and SD-OCT findings, including the size of the IMH and the disruption of the boundary line between inner segments (IS) and outer segments (OS) of the photoreceptors. The data were analyzed using the statistical software SPSS14.0. The correlation among various data was analyzed by Bivariate correlation. The pre-and post-operative data were compared by paired-samples t-tests. RESULTS: Thirty two eyes of 32 patients were studied. The mean logMAR was 1.16 ± 0.46 (ranged from 0.40 to 2.00), the mean diameter of macular hole was (859.7 ± 292.0) µm (ranged from 332 to 1568 µm). The mean diameter of IS/OS disruption was (1965.1 ± 584.1) µm (ranged from 867 to 3444 µm). In eyes after surgery, the mean logMAR was 0.89 ± 0.46 (ranged from 0.30 to 2.00), the mean diameter of the IS/OS disruption was (1350.4 ± 642.6) µm (ranged from 153 to 2546 µm), both were decreased significantly as compare with the preoperative data (t = 3.384, 6.360; P < 0.05). Preoperative diameter of macular hole (r = 0.583) and IS/OS disruption (r = 0.416) were correlated significantly with postoperative logMAR (P < 0.05). CONCLUSIONS: Preoperative diameter of macular hole and IS/OS disruption play the main role in vision prognosis. The IS/OS disruption is decreased significantly after the operation.

RESUMO

OBJECTIVE: To analyze the tomographic features of branching vascular networks and polypoidal lesions in patients with polypoidal choroidal vasculopathy (PCV) by spectral domain optical coherence tomography (SD-OCT). METHODS: It was a retrospective case series study. Retrospective review of 63 eyes of 54 patients with PCV identified with indocyanine green angiography (ICGA). Tomographic features of branching vascular networks and polypoidal lesions on SD OCT, ICGA and fluorescein angiography were analyzed. RESULTS: Both branching vascular network and polypoidal lesions were found in 45 eyes on ICGA, branching vascular network only was found in 8 eyes and polypoidal lesions only in 10 eyes. Retinal pigment epithelial detachment (RPED) was found in all 53 eyes with branching vascular networks on SDOCT. Thirty-eight eyes had areas of moderate reflectivity of branching vascular network between the fluctuating retinal pigment epithelium and Bruch membrane. Fifteen eyes had moderate reflectivity of branching vascular network and/or hemorrhage between high doom-like RPED and incomplete Bruch membrane. Solitary polypoidal lesions in 28 patients showed local moderate reflectivity between the RPE and Bruch membrane on SDOCT. Other aggregate polypoidal lesions in 27 patients showed moderate reflectivity between high doom-like RPED and incomplete Bruch membrane. CONCLUSION: The vascular abnormalities of PCV identified with ICGA were visualized on SD-OCT images as areas of moderate reflectivity between RPE and Bruch membrane.

RESUMO

OBJECTIVE: To assess the relationship between central visual acuity and retinal volume of macular fovea in patients with Stargardt disease by spectral-domain optical coherence tomography (SD OCT). METHODS: It was a retrospective case series study. Twenty eyes of 10 patients with Stargardt disease were investigated by three-dimensional spectral-domain optical coherence tomography. SD OCT images were obtained and retrospectively analyzed. The retinal volumes of macular fovea were measured by SD OCT, whose diameters were set as 3 mm and 1 mm separately (volume 3 and volume 1). The retinal thickness of macular fovea (macular thickness) and the width of IS/OS conjunction loss of macular fovea (IS/OS loss) were also measured by SD OCT. We correlated the logMAR BCVA with IS/OS loss, macular thickness, volume 3 and volume 1 by linear regression analysis. RESULTS: LogMAR BCVA was from 0.3 to 1.22. IS/OS loss was from 847 µm to 5306 µm. Macular thickness was from 20 µm to 126 µm. Volume 3 and volume 1 was from 1.06 to 1.76 mm(3) and 0.06 to 0.13 mm(3). LogMAR BCVA correlated with the IS/OS loss (r = 0.695, P < 0.05), macular thickness (r = -0.601, P < 0.05), and volume 3(r = -0.725, P < 0.05). LogMAR BCVA did not correlate with volume 1(r = -0.364, P > 0.05). CONCLUSIONS: SD OCT could demonstrate the retinal structure of Stargardt disease clearly. The retinal volume of macular fovea accessed by SD OCT correlated with the visual acuity of Stargardt disease.

RESUMO

OBJECTIVE: To study the correlation of visual acuity and photoreceptor in eyes with persistent cystoid macular edema associated with branch retinal vein occlusion (BRVO). METHODS: It was a retrospective case series study.Medical records of 41 patients (41 eyes) with persistent cystoid macular edema secondary to BRVO diagnosed in Department of Ophthalmology, Peking Union Medical College Hospital from January 2008 to January 2010 were studied retrospectively. On the images obtained by spectral-domain OCT, the thickness of foveal neurosensory retina and photoreceptor layer that was beneath the foveal cystoid spaces, and the transverse length and height of foveal cystoid spaces were measured. The status of the junction between inner and outer segments of the photoreceptors (IS-OS) in the fovea was also assessed. The correlations between the parameters above and visual acuity were analyzed. RESULTS: The average foveal neurosensory thickness was (484.71 ± 131.86) µm, the photoreceptor layer thickness was (92.04 ± 45.53) µm and the size of foveal cavity was 772.59 µm × 362.17 µm. By the Spearman's rank correlation analysis, among the parameters above, only photoreceptor layer thickness showed correlation with logMAR visual acuity (r = -0.373, P = 0.016), while other parameters showed no correlation with logMAR visual acuity. Cases were classified as three groups according to the status of IS-OS layer: continuous group (8 cases), discontinuous group (19 cases) and interrupted group (14 cases). LogMAR visual acuity in these eyes with an interrupted IS-OS line in the fovea was significantly worse than that in eyes with a continuous or discontinuous IS-OS line (P = 0.030 and 0.003, respectively). There was no statistical difference between continuous and discontinuous group (P = 0.750). CONCLUSIONS: In patients with persistent cystoid macular edema associated with BRVO, the thickness of the foveal photoreceptor layer are positively associated with visual acuity, and the eyes without IS-OS layer have worse visual acuity than eyes with IS-OS layer.

RESUMO

OBJECTIVE: To describe features of vitreomacular traction syndrome (VMT) on three-dimensional (3D) spectral-domain optical coherence tomography (SD OCT). METHODS: Eighteen eyes of 18 patients with VMT were diagnosed by SD OCT. SD OCT images were obtained and retrospectively analyzed. These VMT cases were defined as focal type or broad type by the region of the vitreous attachment to the macula. The relationship between the logMAR best corrected visual acuity (BCVA) and the retinal thickness of macular fovea was evaluated by linear regression analysis. RESULTS: SD OCT provided detailed 3D images of VMT and revealed information about the extent of vitreomacular traction. Focal VMT was seen in 14 eyes. Broad VMT was seen in four eyes. Eight cases had concurrent epiretinal membrane in the areas surrounding the fovea. Two cases had concurrent full thickness macular hole and two cases had concurrent lamellar macular hole. LogMAR BCVA correlated with the retinal thickness of macular fovea (r = 0.616, P = 0.007, linear regression analysis). CONCLUSIONS: SD OCT allows good visualization of the architectural morphology of the vitreous and retina in vitreomacular traction syndrome. It is useful and irreplaceable for the diagnosis and follow-up of VMT.

RESUMO

AIM: To analyze changes in amplitude of low-frequency fluctuations (ALFFs) and default mode network (DMN) connectivity in the brain, using resting-state functional magnetic resonance imaging (rs-fMRI), in high myopia (HM) patients. METHODS: Eleven patients with HM (HM group) and 15 age- and sex-matched non-HM controls (non-HM group) were recruited. ALFFs were calculated and compared between HM group and non-HM group. Independent component analysis (ICA) was conducted to identify DMN, and comparisons between DMNs of two groups were performed. Region-of-interest (ROI)-based analysis was performed to explore functional connectivity (FC) between DMN regions. RESULTS: Significantly increased ALFFs in left inferior temporal gyrus (ITG), bilateral rectus gyrus (REC), bilateral middle temporal gyrus (MTG), left superior temporal gyrus (STG), and left angular gyrus (ANG) were detected in HM group compared with non-HM group (all P<0.01). HM group showed increased FC in the posterior cingulate gyrus (PCC)/precuneus (preCUN) and decreased FC in the left medial prefrontal cortex (mPFG) within DMN compared with non-HM group (all P<0.01). Compared with non-HM group, HM group showed higher FC between mPFG and bilateral middle frontal gyrus (MFG), ANG, and MTG (all P<0.01). In addition, HM patients showed higher FC between PCC/(preCUN) and the right cerebellum, superior frontal gyrus (SFG), left preCUN, superior frontal gyrus (SFG), and medial orbital of the superior frontal gyrus (ORB supmed; all P<0.01). CONCLUSION: HM patients show different ALFFs and DMNs compared with non-HM subjects, which may imply the cognitive alterations related to HM.
