ABSTRACT
There is limited understanding of the inter-compartmental progression and treatment outcomes of primary central nervous system lymphoma (PCNSL). In this multicenter retrospective cohort study on 234 patients with PCNSL (median age: 62.5 years [18-92]; median follow-up 35 months [0.1-237.0]) from 2000 till 2018 were divided into group 1 (ocular, 44 patients): 1A and 1B without and with CNS progression and group 2 (CNS, 190 patients): 2A and 2B without and with ocular progression, respectively. In group 1 (44 patients), 33 patients received local treatment, and 11 patients received systemic treatment. In group 2 (15 patients), six patients received combination treatment, while seven patients received only systemic treatment. A complete response was observed in 19 (43%) and 91 (48%) patients in groups 1 and 2, respectively. The 2-year progression-free survival (PFS) was 35% (95% CI: 0.23, 0.54) and 56% (95% CI: 0.49, 0.63) for groups 1 and 2, respectively (p < 0.0001). Age < 60 years was significantly associated with longer PFS (median PFS 48 vs. 24 months, p = 0.01). The overall survival (OS) at 2-year was similar among groups 1 and 2 (83% and 67%), respectively (p = 0.06). Thus, Initial compartment of involvement does not influence local response rate or OS.
ABSTRACT
PURPOSE: To determine predictive factors of proliferative vitreoretinopathy (PVR) formation after uncomplicated primary retinal detachment repair. METHODS: Retrospective, single-center, case-control study of 74 consecutive patients with (37 eyes) and without (37 eyes) PVR formation after undergoing uncomplicated primary surgery for retinal detachment repair. Logistic regression was used to assess factors associated with PVR formation. RESULTS: Retinal detachment involving the macula was 4.2 times (adjusted odds ratio; 95% confidence interval, 1.4-12.9; P = 0.0119) more likely to have PVR formation compared with those without. Patients who were current or former smokers were 3.6 times (adjusted odds ratio; 95% confidence interval, 1.1-11.7; P = 0.0352) more likely to have PVR formation compared with nonsmokers. Compared with 25-gauge (g) vitrectomy, larger gauge vitrectomy (20 g or 23 g) was 3.6 times (adjusted odds ratio; 95% confidence interval, 1.2-11.3; P = 0.0276) more likely to have PVR formation. Duration of retinal detachment symptoms, high myopia, lens status, lattice degeneration, location of retinal break, number of retinal breaks, and surgical technique (e.g., scleral buckle with or without vitrectomy versus vitrectomy alone) were not found to be predictive of PVR formation. CONCLUSION: Cigarette smoking and macular involvement are significant risk factors predictive of PVR formation after uncomplicated primary retinal detachment repair.

PURPOSE: To determine the outcomes in patients with rhegmatogenous retinal detachment (RRD) secondary to viral retinitis. PATIENTS AND METHODS: This was a retrospective, consecutive, noncomparative, interventional case series of 12 eyes in ten patients with RRD secondary to viral retinitis. Results of vitreous or aqueous biopsy, effect of antiviral therapeutics, time to retinal detachment, course of visual acuity, and anatomic and surgical outcomes were investigated. RESULTS: There were 1,259 cases of RRD during the study period, with 12 cases of RRD secondary to viral retinitis (prevalence of 0.95%). Follow-up was available for a mean period of 4.4 years. Varicella zoster virus was detected in six eyes, herpes simplex virus in two eyes, and cytomegalovirus in two eyes. Eight patients were treated with oral valacyclovir and two patients with intravenous acyclovir. Lack of optic nerve involvement correlated with improved final visual acuity of 20/100 or greater. Pars plana vitrectomy (n=12), silicone-oil tamponade (n=11), and scleral buckling (n=10) provided successful anatomic retinal reattachment in all cases, with no recurrent retinal detachment and no cases of hypotony during the follow-up period. CONCLUSION: Varicella zoster virus was the most frequent cause of viral retinitis, and lack of optic nerve involvement was predictive of a favorable visual acuity prognosis. Vitrectomy with silicone-oil tamponade and scleral buckle placement provided stable anatomical outcomes.
