Localized, central optic snowflake degeneration of a polymethyl methacrylate intraocular lens: clinical report with pathological correlation.
tral retinal vein occlusion, and retinal detachment. Although data in the literature regarding the presence of VEGF in uveal melanoma are conflicting, our report shows the presence of VEGF in an iris melanoma. Kvanta and colleagues demonstrated the presence of VEGF protein in retinoblastoma but not in posterior uveal melanomas. Similarly, in a study of VEGF expression in central retinal vein oc...
متن کاملComparison of decentration and tilt between one piece and three piece polymethyl methacrylate intraocular lenses.
BACKGROUND The extent of the decentration and tilt was prospectively compared between one piece polymethyl methacrylate (PMMA) and three piece PMMA intraocular lenses (IOLs) which were implanted in the capsular bag after performing continuous curvilinear capsulorhexis. METHODS 91 patients underwent a one piece PMMA IOL implantation in one eye as well as the implantation of the three piece PMM...
متن کاملSynthesis and thermal characterization of polymethyl methacrylate
PMMA with molecular mass (PMMA Mw: 1.2×105) was synthesized through AIBN initiated free radical polymerization methyl methacrylate at 100 ± 1°C.The synthesized polymer was characterized through GPC coupled with RI detector in presence of THF as mobile phase at 1.0 mL/ min and simultaneous TG-DTA-DTG in nitrogen. TG data were used to investigate the non-isothermal kinetics of solid-state decompo...
متن کاملSalvage of Infected Nasal Reconstruction with a Polymethyl Methacrylate Spacer
Total nasal reconstruction is a challenging multistage procedure. Infections can destroy the cartilage framework and seriously compromise the result. The use of polymethyl methacrylate with antibiotics as a spacer has been described in the treatment of skeletal infections. Using this same principle, the use of a polymethyl methacrylate with antibiotics spacer for an infected nasal reconstructio...
متن کاملA comparison of 141 polymacon (Iogel) and 140 poly(methyl methacrylate) intraocular lens implants.
In a prospective controlled trial 290 consecutive patients were randomly allocated a polymacon or a poly(methyl methacrylate) (PMMA) intraocular lens. Early Treatment of Diabetic Retinopathy Study (ETDRS) acuity charts gave similar results with both lenses. However Pelli-Robson contrast sensitivity charts gave a better result with PMMA lenses. Polymacon lenses appeared to remain free of any adh...
