Title: Outcomes of congenital cataract surgery with intra-operative intra-cameral triamcinolone injection versus postoperative oral prednisolone
Biography: Marcelo C Ventura
Congenital cataract is an important cause of reversible blindness in childhood. Early diagnosis and surgery, adequate refractive error correction and aggressive amblyopia management improve these patients’ visual prognosis. However, early cataract surgery is associated with greater risk of complications, possibly due to the enhanced inflammatory response and the more reactive vitreous face in children. The use of corticosteroids for modulating postoperative ocular inflammation was established decades ago. Topical and systemic corticosteroid administration results in effective intraocular concentrations. However, they do not maintain long adequate concentrations of the drug in the aqueous humor, which is compensated by frequent doses in the postoperative period. This, in turn, increases the risk of adverse events. Moreover, caregivers do not always adhere to the instructions for administering drugs postoperatively, a scenario favoring complications that may compromise the visual prognosis. In contrast, intraocular injection of corticosteroid delivers an adequate and sustained quantity of the drug to the target tissue. Triamcinolone acetonide is a deposit corticosteroid with low water solubility, which contributes to its prolonged action. It has been increasingly used in ophthalmology as a vitreous dye in children and adults, as well as to modulate intraocular inflammation after phacoemulsification in adults. However, its use is not exempt of risks. Thus, we conducted a series of studies to investigate and compare the use of intracameral triamcinolone at the end of the procedure versus the conventional use of postoperative oral prednisolone for modulating intraocular inflammation in children that undergo congenital cataract surgery younger than 2 years of age.
