PURPOSE:The purpose of this study is to evaluate patients with uveal metastasis based on primary tumor site.METHODS:Retrospective analysis from Wills Eye Hospital, Philadelphia, PA, USA, for uveal metastasis clinical features and outcomes based on the primary tumor site.RESULTS:There were 2214 uveal metastases diagnosed in 1111 consecutive patients. The demographics included mean age of 60 years (median 61 years), Caucasian race (88%), and female gender (64%). The tumor was unilateral (82%) and primary site was established before uveal metastasis (67%). The primary tumor originated in the breast (37%), lung (26%), kidney (4%), gastrointestinal (GI) tract (4%), cutaneous melanoma (2%), lung carcinoid (2%), prostate (2%), thyroid (1%), pancreas (1%), other sites (3%), and unknown (16%). Comparative analysis of the 5 most common primary sites (breast, lung, kidney, GI tract, and cutaneous melanoma), revealed metastasis at mean age (57, 62, 66, 61, 59 years), as unilateral tumor (74%, 86%, 85%, 93%, 85%), with mean number of metastasis/eye (1.9, 1.7, 1.0, 1.1, 2.0), and in females (99%, 46%, 26%, 25%, 30%). Choroidal metastases measured mean base (9.3, 10.2, 9.1, 11.0, 7.3 mm), mean thickness (2.4, 3.6, 4.4, 4.0, 2.9 mm), and demonstrated predominant color yellow (94%, 91%, 56%, 97%, 36%). Of the 769 patients with documented follow-up, mean patient survival was poor (22.2, 11.5, 8.6, 12.4, 11.4 months) and Kaplan–Meier analysis revealed 3-year survival (33%, 19%, 0%, 14%, 21%) and 5-year survival (24%, 13%, 0%, 14%, 21%). The worst survival was found in patients with pancreatic metastasis (mean 4.2 months) and best survival with lung carcinoid (92% at 5 years).CONCLUSION:In a tertiary referral service, uveal metastasis originates from cancer in the breast, lung, kidney, GI tract, cutaneous melanoma, or others. Overall prognosis is poor with 5-year survival at 23% and worst survival with pancreatic metastasis whereas best survival with lung carcinoid metastasis.

Purpose of reviewDiabetic retinopathy (DR) is one of the leading causes of preventable vision loss in the world and its prevalence continues to increase worldwide. One of the ultimate and visually impairing complications of DR is proliferative diabetic retinopathy (PDR) and subsequent tractional retinal detachment. Treatment modalities, surgical techniques, and a better understanding of the pathophysiology of DR and PDR continue to change the way we approach the disease. The goal of this review is to provide an update on recent treatment modalities and outcomes of proliferative diabetic retinopathy and its complications including tractional retinal detachment. Recent findingsPanretinal photocoagulation (PRP), anti-vascular endothelial growth factor (anti-VEGF), and pars plana vitrectomy are the mainstay of PDR treatment. However, PRP and anti-VEGF are associated with significant treatment burden and multiple subsequent treatments. Early vitrectomy is associated with vision preservation, less treatment burden, and less subsequent treatments than therapy with PRP and anti-VEGF. SummaryConcerning costs, high rates of noncompliance in the diabetic population and significant rates of subsequent treatments with initial PRP and anti-VEGF, early vitrectomy for diabetic retinopathy in patients at risk of PDR is a cost-effective long-term stabilizing treatment for diabetics with advanced disease.

PurposeTo investigate demographics and clinical features of patients with amelanotic choroidal tumours.DesignRetrospective analysis.MethodsComparison of demographic and clinical features of various amelanotic choroidal tumours based on stratification by patient age, sex and tumour diameter. Included were all patients with amelanotic choroidal tumours evaluated on the Ocular Oncology Service, Wills Eye Hospital, Philadelphia, Pennsylvania, USA, over a 45-year time period.ResultsA total of 5586 amelanotic choroidal tumours in 4638 eyes of 4441 patients were included with a mean age at presentation of 58 years (median 60, range 0.1–100 years). Most patients were white (95%), female (56%) and with unilateral lesion (96%). By comparison, amelanotic melanoma presented at a younger mean age (57 years) compared with metastasis (60 years, p<0.001), nevus (61 years, p<0.001), lymphoma (65 years, p<0.001), sclerochoroidal calcification (70 years, p<0.001) and peripheral exudative haemorrhagic chorioretinopathy (80 years, p<0.001). Melanoma presented at an older mean age compared with osteoma (30 years, p<0.001), granuloma (42 years, p<0.001), haemangioma (49 years, p<0.001) and inflammatory choroidal lesions (49 years, p<0.001). Differences in race and sex were also seen between the various amelanotic choroidal lesions. With few exceptions, amelanotic melanoma had significantly larger basal diameter, greater thickness, more frequent association with subretinal fluid and more often ultrasonographically hollow, compared with other amelanotic choroidal lesions.ConclusionUnderstanding the demographic and clinical features of amelanotic choroidal melanoma and other amelanotic lesions could lead to an earlier and more accurate diagnosis.

PurposeTo evaluate interval between primary cancer diagnosis and uveal metastasis and assess survival outcomes based on whether the primary cancer was diagnosed before or after uveal metastasis.MethodsIn this retrospective analysis, all patients with uveal metastasis evaluated on the Ocular Oncology Service, Wills Eye Hospital, Philadelphia, PA, USA between February 1, 1974 and June 1, 2017 were included. Features and outcomes based on timing of primary cancer diagnosis, whether before or after diagnosis of uveal metastasis, were assessed.ResultsA total of 2214 uveal metastases were diagnosed in 1310 eyes of 1111 consecutive patients. Primary cancer was known prior to uveal metastasis in 742 patients (67%) and not known in 369 (33%). Of those not known, the primary cancer was later found in 192 patients (17%) and never found in 177 patients (16%). For those with known primary cancer, mean interval from primary cancer diagnosis to uveal metastasis was 5.2 years with differences in primary sites of gastrointestinal (2.1 years, p = 0.003), lung (2.2 years, p < 0.001), breast (6.5 years, p < 0.001), and thyroid (13 years, p < 0.001). By Kaplan-Meier analysis, the 5-year overall survival showed no difference between patients with primary cancer found before (28%) vs after (20%) vs never found (33%), relative to uveal metastasis.ConclusionOf 1111 patients with uveal metastasis, early-onset uveal metastases were found with lung and gastrointestinal tract cancers, whereas late-onset metastases were found with breast and thyroid cancers. Overall survival did not vary on whether the primary tumor was diagnosed before, after, or never found, relative to uveal metastasis.

Purpose: To evaluate clinical features and survival outcomes of uveal metastasis based on patient age. Methods: Retrospective analysis of all patients with uveal metastasis evaluated on the Ocular Oncology Service, Wills Eye Hospital, Philadelphia, PA, USA between February 1, 1974 and June 1, 2017. The features and outcomes were analyzed based on patient age classified as children (0–20 years), young adults (21–40 years), middle [aged] adults (41–60 years), older adults (61–80 years) and senior adults (81–100 years). Results: There were 1111 consecutive patients, including children (n = 3, <1%), young adults (n = 77, 7%), middle adults (n = 472, 42%), older adults (n = 509, 46%), and senior adults (n = 50, 4%). At uveal metastasis diagnosis, demographics included mean patient age of 60 years, Caucasian race (88%), and female gender (64%). Compared to the largest cohort (older adults), there were significant differences (age group versus [vs.] older adults) in Caucasian race (senior adult 98% vs. 89%, p = 0.042), male sex (young adults: 22% vs. 43%, p < 0.001) (middle adults: 29% vs. 43%, p < 0.001), unilateral tumor (young adult: 70% vs. 86%, p < 0.001) (middle adult: 79% vs. 86%, p = 0.003) (senior adults: 96% vs. 86%, p = 0.045), and cancer origin in breast (young adults: 51% vs. 32%, p = 0.002) (middle adults: 44% vs 32%, p < 0.001), lung (young adults: 14% vs. 30%, p = 0.004), kidney (young adults: 0% vs. 5%, p = 0.043), prostate (middle adults: 1% vs. 4%, p = 0.001), gastrointestinal tract (senior adults: 8% vs. 2%, p = 0.028), and others (children: 100% vs. 4%, p < 0.001) (young adults: 10% vs. 4%, p = 0.044). Kaplan-Meier survival (children, young, middle, older, and senior adults) at 1 year was 33%, 48%, 60%, 62%, and 76% and at 5 years was 0%, 22%, 29%, 25%, and 40%, respectively, with no difference per age category. The mean overall survival was 17.2 months and children demonstrated hazard ratio (HR) for death at 1 year of 2.1 relative to older adults. Conclusion: Uveal metastasis is found in all age groups. Compared to older adults, primary cancer site was more often breast and less likely lung in young and middle adults. Other rare sites were more often seen in children. Survival outcomes at 1 and 5 years were most favorable for senior adults and least favorable for children.
