Intravitreal Carboplatin for the Treatment of Participants With Recurrent or Refractory Intraocular Retinoblastoma
Retinoblastoma (RB) is the most common intraocular tumor of childhood. Recurrent or refractory disease following therapy most often occurs due to persistence of vitreous disease and/or retinal reactivation of the main tumor mass. With this treatment protocol, investigators seek to identify a less invasive method of local drug delivery that does not disrupt the eye's integrity. PRIMARY OBJECTIVE: To determine the safety and toxicity profile associated with intravitreal carboplatin for the treatment of recurrent or progressive intraocular retinoblastoma with vitreous seeding. SECONDARY OBJECTIVES: To estimate the ocular salvage rate after treatment with intravitreal carboplatin in patients with recurrent or progressive intraocular retinoblastoma with vitreous seeding. To evaluate the effects of intravitreal carboplatin therapy on the histopathology of eyes enucleated for progressive or recalcitrant disease while on therapy.
A Modified 48 Hour Patch Test of Neo-Synalar Cream, Sodium Lauryl Sulfate (Positive Control) and Saline (Negative Control)
A 48 hour patch test performed in healthy volunteers to determine the presensitization (pre-existing allergy) of Neo-Synalar (neomycin sulfate 0.5%(0.35% neomycin base), fluocinolone acetonide 0.025%) Cream . Subjects also receive a positive control (Sodium Lauryl Sulfate) and a negative control (Saline). The primary objective of this study is to determine if any subjects exhibit an allergic reaction which may be indicative of a pre-existing sensitization.
