ABSTRACT
PURPOSE: To describe postoperative complications in a patient with a giant retinal tear and heavy silicone oil endotamponade. METHODS: Case report. RESULTS: A 16-year-old girl with a giant retinal tear underwent 20-gauge three-port pars plana vitrectomy with scleral buckling and heavy silicone oil endotamponade (Oxane HD; Bausch & Lomb, Toulouse, France). During follow-up, early emulsification of the silicone oil and severe secondary membrane proliferation within the silicone oil and retinal interface were detected. Exchange of silicone oil (5,000 centistokes) and membrane removal were performed. Histologic evaluation revealed fibrosis and a foreign body-type reaction. CONCLUSION: Secondary proliferations may become a provoked inflammatory response to heavy silicone oil; therefore, further controlled clinical trials should be performed to evaluate these potential side effects before heavy silicone oil is routinely used as a temporary vitreous substitute in eyes with complicated retinal detachments.
ABSTRACT
OBJECTIVE: To assess the effect of sildenafil citrate treatment on visual field analysis (VFA) in patients using sildenafil citrate for erectile dysfunction. MATERIALS AND METHODS: In this prospective study on 18 male volunteers with erectile dysfunction, bilateral VFA was performed using the Humphrey 30-2 central standard threshold test. White-on-white (W/W) and blue-on-yellow (B/Y) protocols were used prior to treatment (baseline VFA) and after treatment (repeat VFA) with sildenafil citrate. W/W and B/Y baseline VFA and repeat VFA mean deviations (MD) were compared. RESULTS: The baseline MD for W/W and B/Y protocols were -1.34 +/- 1.8 and -2.59 +/- 2.1 dB, respectively, whereas the mean repeat MD for W/W and B/Y protocols were -1.79 +/- 2.21 and -2.83 +/- 3.31 dB, respectively. There was no statistically significant difference between W/W and B/Y baseline and repeat VFA with respect to MD (p > 0.05). CONCLUSION: Sildenafil citrate causes no significant changes in Humphrey VFA in patients with erectile dysfunction.
