39. Frosted branch angiitis following corneal tear repair.

Author

Abstract

We report a patient who developed frosted branch angiitis (FBA) and was diagnosed 1 month after the penetrating eye injury (PEI) repair. A 31-year-old male with no systemic comorbidities presented with defective vision following trauma to his left eye while cutting wood. His best-corrected visual acuity (BCVA) was 20/200. Anterior segment examinations showed a zone I full-thickness corneal tear with iris tissue incarceration. There was no clinical evidence of intraocular foreign body (IOFB) or endophthalmitis. He underwent PEI repair with iris abscission on the same day with intracameral moxifloxacin injection. His BCVA on postoperative day 45 was 20/200. Examination showed a resolving vitreous hemorrhage, venous tortuosity, and retinal perivascular infiltration affecting the venules from the posterior pole up to the periphery. He was treated with oral and topical steroids. The clinical signs resolved completely and BCVA improved to 20/20 after 1 month of treatment. FBA can complicate the recovery of eyes after PEI repair, even in the absence of endophthalmitis or sympathetic ophthalmia. A thorough search for IOFB or its tell-tale signs should be done in such eyes. [ABSTRACT FROM AUTHOR]

Abstract

In this paper we report for the first time synthesis of Eu3+-doped transparent glass-ceramics ( TGC) with BaBi2Ta2O9 ( BBT) as the major crystal phase using the glass system SiO2-K2O-BaO-Bi2O3-Ta2O5 by melt quenching technique followed by controlled crystallization through ceramming heat treatment. DSC studies were conducted in order to determine a novel heat-treatment protocol to attain transparent GCs by controlling crystal growth. The structural properties of the BBT GCs have been investigated using XRD, FE- SEM, TEM and FTIR reflectance spectroscopy. Optical band gap energies of the glass-ceramic samples were found to decrease with respect to the precursor glass. An increased intensity of emission along with increase in the average lifetime of Eu3+ was observed due to incorporation of Eu3+ ions into the low-phonon energy BBT crystal site. The local field asymmetric ratios of all the samples were observed greater than unity. The dielectric constant (εr), dielectric loss, and dissipation factor values of both the base glass and ceramized samples were found to decrease with increase in frequency. [ABSTRACT FROM AUTHOR]
