متن کاملComparison of Convective Transport of Drug between Intravitreal Injection and Controlled Release Implant
It is important to know the drug distribution following administration of drug in order to properly treat with adequate dosage and thus, avoid damage to tissues due to excessive high concentrations. A computer model was developed to determine drug distribution by convective-diffusive transport processes in a rabbit eye. When compared with pure diffusion within vitreous, the ratio of the amount ...
متن کامل[Technique of intravitreal drug injection for therapy of vitreoretinal diseases].
Intravitreal injections are the standard technique applied in the treatment of some vitreoretinal diseases. In this paper the technique and complications of intravitreal injections are presented. In summary, the procedure involves various consecutive steps. Initially, days before the treatment topical antibiotics and acetazolamide may be prescribed for reduction of the ocular flora and intraocu...
متن کاملSuprachoroidal Air Injection for Detached Retina
INJECTION of air into the eye is considered by some authors to be useful in certain cases of detached retina (Spaeth, 1941). Where a considerable quantity of subretinal fluid has been evacuated, with consequent collapse of the globe, there are two ways in which the eye may regain its shape and tension. Either the subretinal fluid may re-form and reproduce the detachment, or aqueous may be forme...
متن کاملComparison of Suprachoroidal Drug Delivery with Subconjunctival and Intravitreal Routes Using Noninvasive Fluorophotometry
PURPOSE To determine whether exposure of sodium fluorescein (NaF) to the choroid-retina region in the posterior segment of the eye is greater with suprachoroidal injection when compared to intravitreal and transscleral routes. METHODS Suprachoroidal injection, a new approach for drug delivery to the posterior segment of the eye was validated using a 34 G needle and Indian ink injections in Sp...
