  • Clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma

    Objective To observe the clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma. Methods Thirty-six uveal metastatic carcinoma patients (43 eyes) were enrolled in this study. The patients included 21 males and 15 females. The patientsprime; ages ranged from 28 to 71 years, with a mean age of (47.3plusmn;10.2) years. Seven patients had bilateral carcinoma and 29 patients had unilateral carcinoma. There were 30 patients with lung cancer, three patients with breast cancer, one patient with gastric cancer and two patients without primary tumors. There were 20 patients with known primary cancer, 16 patients visited the Department of Ophthalmology first. All the patients were examined documenting visual acuity, intraocular pressure, slit-lamp microscopy and mydriatic fundus examination. Meanwhile, 22 patients (26 eyes) were examined using B-type ultrasound and/or color Doppler flow imaging (CDFI). Twelve patients (12 eyes) were examined using fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA). Seventeen patients (22 eyes) were examined using MRI and/or CT. The clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma patients were observed. Results Among 43 eyes, four lesions were in the iris, three lesions in the ciliary body and 32 lesions were in the choroid. Fundus examination showed an isolated mass in 26 eyes and more than two masses in nine eyes. Metastatic tumors of the iris and ciliary body often showed irregular cauliflower-like mass with gray-white or meat-red color and abundant vessels. The choroidal metastasis usually demonstrated flat rounded or irregular intraocular masses with gray-yellow or gray-white color in the posterior pole. B-type ultrasound showed ill-defined, flat, and irregular-shaped masses with uneven internal reflectivity. CDFI showed rich blood flow within the tumor. FFA and (or) ICGA showed pinpoint and mottled leaks against hyperfluorescence background. MRI revealed low or middle signal using T1WI and low signal intensity using T2WI. Conclusions The uveal metastatic carcinoma usually occurs in one eye with an isolated mass. Most of them show a flat gray-yellow mass in posterior choroids and have the primary cancer sites of the lung. FFA and/or ICGA show pinpoint and mottled leaks against hyperfluorescence background. B-type ultrasound and (or) CDFI show ill-defined, flat, and irregular-shaped mass with rich blood flow within the tumor. MRI reveals low signal intensity on T2WI.

  • The ocular features and misdiagnosis of intraocular non-Hodgkin's lymphoma

    Objective To observe the ocular features and analyze the cause of misdiagnosis of intraocular nonHodgkin's lymphoma (IONHL). Methods A retrospective study was performed in 6 patients and related literatures were reviewed. The age of those patients was 46 to 68 yrs with an average of 562 yrs. Four cases were female, two cases were male. Five patients were unilateral and one case was bilateral case. All patients were investigated by Goldmann tonometer, fundus fluorescein angiography (FFA) and ophthalmic Bscan. Pathological samples come from enucleation and vitrectomy, and were analyzed histologically and immunohistochemically. Results Ophthalmological signs of IONHL included decrease visual acuity, red eye, aqueous flare; keratic precipitates (Kp), vitreous opacity, retinal detachment and multiple whiteyellow retinal lesions of different sizes and fuzzy boundaries. IONHL patients were always misdiagnosed as diverse and nonspecific symptoms and signs, two cases were misdiagnosed as retinitis or chorioiditis, one case as intermediate uveitis, one case as secondary glaucoma in uveitis. The duration from onset of symptom and sign to a final diagnosis was from 6 months to 24 months with an average of 13.3 months. Conclusions The clinical manifestation of IONHL was diverse and non-specific,and this disease was unknown to lots of doctors and easily be misdiagnosed.

  • Analysis of multiple factors affecting the prognosis of local excision for uveal melanoma

    Objective To observe the therapeutic effects and security of the local resection for uveal melanoma, and to detect the factors which affect the prognosis. Methods The clinical data of 45 patients with uveal melanoma who had undergone local resection after examined by histopathology were retrospectively analyzed, including the age,sex,the longest diameter, the location of the tumor,with or without retinal detachment, intraocular pressure (IOP) and visual acuities before and after the operation, and the visual acuity. The relationship between the therapeutic method and the survival prognosis was analyzed. COX regression model was set up with knubbly metastasis relapse prognosis and the multiple factors which was the assistive variables. Results Among these factors, the metastasis and relapse had obvious relation to the longest diameter and height of the tumor(P=0.04), the IOP after operation(P=0.03), pathologic classification (P=0.04)、with or without scleral infiltration (P=0.03)、the location of the tumor (P=0.01) and complete or incomplete resection (P=0.00). The period when the metastasis and relapse of tumor were most likely to happen was 20 to 40 months. Conclusion Local resection is one of the effective methods for uveal melanoma. These patients should be followed up closely from 20 to 40 months after operation, and if necessary, should be treated combined with other treatments. (Chin J Ocul Fundus Dis, 2006, 22: 154-156)

  • Preliminary study on the application of 18-Fluorine-labelled 2-deoxy-2-fluoro-D-glucose positron emission tomography/computed tomography in uveal melanoma

    ObjectiveTo assess the use of 18-Fluorine-labelled 2-deoxy-2-fluoro-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) in the diagnosis of uveal melanoma. MethodsTwenty-three patients with uveal melanoma confirmed by histopathologic examination or imaging examination were enrolled. There were 16 male, 7 female, and the mean age was (49.8±12.3) years. All the lesions were unilateral, with 11 cases in OD, 12 cases in OS. Diagnosis was confirmed by histopathological examination of enucleated eyeballs in 15 cases, by ophthalmoscope, fundus fluorescein angiography, ocular B-mode ultrasound and magnetic resonance imaging and other imaging technology in 8 cases. 15 patients diagnosed by histopathologic examination of enucleated eyeballs were divided into three types including mixed (7 patients), spindle cell (6 patients) and epithelioid cell (2 patients) types. The mixed cell type and epithelioid cell type are considered as high-risk; spindle cell type is low-risk. All the patients were evaluated by whole body PET/CT. The location, size, shape, boundary of the lesions, and the relationship with adjacent structures were observed in CT images. 18F-FDG uptake was quantitative expression by standardized uptake value (SUV) in PET image; positive diagnosis should be made when the maximum standardized uptake value (SUVmax) was not less than 2.5. The correlation between SUVmax and maximum diameter of tumor base, tumor height was analyzed by Spearman rank correlation test. The detection rate of high-risk and low-risk patients between 18F-FDG PET and CT methods was comparative analyzed. ResultsAll the CT images showed abnormal high density ocular lesions. The shape of the lesions included 8 patients of semi sphere-like, 7 patients of flat-like, 4 patients of mushroom-like, 3 patients of round-like and 1 patient of diffuse lesions. The tumors were located in the posterior pole (9 patients), temporal equator (5 patients), nasal equator (4 patients), superior equator (1 patient), temporal ciliary body (1 patient), inferior ciliary body (1 patient), temporal iris (1 patient), and nasal iris and ciliary body (1 patient). SUVmax≥2.5 were found in 9 patients (39.13%), the largest basal diameter and height were (17.53±3.48), (11.37±3.85) mm respectively. SUVmax < 2.5 were found in 14 patients (60.87%), the largest basal diameter and height were (10.66±3.25), (5.33±2.23) mm respectively. The former's largest basal diameter and height were greater than the latter's and the difference was statistically significant (t=4.815, 4.786; P < 0.01). SUVmax was positively correlated with the largest basal diameter and height respectively (r=0.881, 0.809; P < 0.01). 15 patients (39.13%) were diagnosed by histopathological diagnosis after enucleation, of which SUVmax≥2.5 were found in 8 patients which included 6 patients of mixed type, 1 patient of epithelioid cell type, and 1 patient of spindle cell type. The detection rate of high-risk type (77.78%, 7/9) was higher than that of low-risk type (16.67%, 1/6), the difference was statistically significant (χ2=5.402, P < 0.05). Conclusions18F-FDG PET-CT examination can show large uveal melanoma tumor from cell metabolism, and may help to evaluate the prognosis of the preoperative patients. But, for small tumor, it has little value. We don't recommend 18F-FDG PET-CT is used as a routine examination for uveal melanoma.

  • The clinical features of primary uveal lymphoma of four cases

    ObjectiveTo investigate the clinical, ophthalmological and pathological features of primary uveal lymphoma.MethodsRetrospective clinical study. From 2012 to 2018 in Beijing Tongren Eye Cener, 4 cases and 4 eyes of patients with primary uveal lymphoma were included in the study. Among them, 3 cases were male and 1 case was female. The average age was (54 ± 13.58) years old. The average time from initial diagnosis to pathological diagnosis was (18.50 ± 9.29) months. 3 cases were enucleated and 1 case was biopsied. Extranodal marginal zone lymphoma (EMZL) of the mucosa associated lymphoid tissue (MALT) was confirmed by pathological examination. BCVA, fundus color photography, color Doppler ultrasound and orbital MRI were performed in all eyes. UBM, OCT, FFA and ICGA were performed in 2 eyes, 3 eyes, 3 eyes and 2 eyes respectively. The clinical, imaging and pathological changes were observed. Following up time was ≥ 6 months.ResultsAt the initial diagnosis, BCVA was 0.6, 0.02 and 0.01 in 1, 2 and 1 eye respectively. Choroid, ciliary body and iris were involved in 3 eyes, choroid in 1 eye. The fundus of the eyes showed infiltration of choroid in yellow and white color, and the lesions were beyond the vascular arch to the equator and peripheral areas. Color Doppler ultrasonography showed that choroidal diffuse thickening and extrascleral extension (ESE) which was the corresponding hypoechoic areas behind the sclera. Among them, ESE showed crescent thickening in 1 eye and nodular thickening in 3 eyes. UBM showed that the echo of ciliary body was thicken and the internal echo was decreased with the iris involved. OCT showed that RPE was wavy and local retinal neuroepithelial layer detached. FFA showed that the early lesions were mottled with strong and weak fluorescence, and the late fluorescence leakage. The posterior wall of the eyeball was thickened and enhanced in MRI.ConclusionThe clinical manifestations of uveal lymphoma are various, color Doppler ultrasound has characteristic manifestations and ESE of crescent or nodular thickening is valuable in diagnosis.
