ObjectiveTo detect the level of serum melanoma-inbibiting activity (MIA) in patients with uveal melanomas, and investigate the value of MIA in diagnosing and inspecting uveal melanomas.MethodsEnzyme-linked immunosorbent assay (ELISA) was used to detect the concentrations of MIA in peripheral serum of 27 patients with uveal melanoma, 6 with melanocyte tumor, 7 with other ocular tumors and 16 healthy individuals, respectively.ResultsThe concentration of MIA in patients with uveal melanoma was significantly higher than that in the healthy ones (16 individuals) and the patients with adenoma of non pigmented ciliary epithelium (4 patients), retinoblastoma (2 patients), and retinal angioma 91 patient). The concnetration of MIA in patients with uveal melanoma without scleral infiltration or remote metastasis was obviously lower than that in the patients with scleral infiltration or remote metastasis, but didn′t differ much from which in the patients with melanocyte tumor. In the patients with uveal melanoma without infiltration or remote metastasis, there was no significant difference of MIA level between patients with spindle cell and mixed and epithelioid cell.ConclusionThe level of serum MIA may be an effective index in diagnosing uveal melanoma, which can monitor the metastasis of uveal melanoma.(Chin J Ocul Fundus Dis, 2005,21:153-155)
ObjectiveTo observe the clinical features of uveal effusion syndrome (UES) and the efficacy of sclerectomy in the treatment of UES.MethodsA retrospective case series. Twenty patients (36 eyes) of UES with sclerectomy were enrolled in this study from June 2012 to December 2016 in Beijing Tongren Hospital. Among them, there were 12 males (22 eyes) and 8 females (14 eyes), with an average age of 37.8 years. All patients suffered from bilateral diseases, including 4 patients in single eye group and 16 patients in double eye group. Visual acuity, intraocular pressure, indirect ophthalmoscope, UBM, FFA combined with ICGA, A/B ultrasonography, axial length (AL) and scleral thickness were measured. All patients underwent lamellar sclerectomy, and those with exudative retinal detachment underwent four quadrant lamellar sclerectomy, followed by four quadrant full-thickness sclerectomy with the size of 1 mm × 2 mm in the center of the scleral bed. The follow-up time after operation was more than 6 months.Visual acuity, intraocular pressure and fundus examination were performed 1, 3 and 6 months after operation with the same equipment and methods before operation.ResultsThere was no obvious inflammation in the anterior chamber of all eyes, and intraocular pressure was 24-28 mmHg (1 mmHg = 0.133 kPa) in 4 eyes (11.1%). Axial length of 8 eyes (22.2%) were 16-18 mm (true microphthalmia). 12 eyes (33.3%) had scleral thickness＞1.0-1.8 mm. Visual acuity ranged from hand movement to 0.05 in 20 eyes, 0.1 to 0.3 in 10 eyes and＞0.3 in 6 eyes. Fundus examination showed peripheral choroidal and ciliary detachment; UBM examination showed annular peripheral ciliary and choroidal detachment. 32 eyes (88.9%) were complicated with exudative retinal detachment. FFA examination showed that 14 eyes (38.9%) had leopard spot changes. Compared with preoperative vision, the visual acuity improved in 28 eyes (77.8%) and remained unchanged in 8 eyes (22.2%) after surgery. Thirty-two eyes with different degrees of retinal detachment were found before surgery. After surgery, ciliary body detachment, choroidal detachment and retinal detachment were restored. Six eyes (16.7%) recurred and underwent sclerectomy again.ConclusionsThe mild symptoms and recurrent attack are the characteristics of UES. Sclerectomy is an effective method to treat UES.
