In small animals such as the rabbit the ratio of eye size to body size is much larger than it is in humans. Accordingly, periocular injection of antibodies in this animal model results in significantly higher serum concentrations than does a comparable does in a human. To assess the effect of the systemic drug component on ocular penetration, we compared the levels of gentamicin in ocular tissu...

Day-case cataract surgery and the need for local anaesthesia are likely to increase. Retrobulbar (and peribulbar) anaesthetic injection is a common technique in cataract surgery, but serious complications are persistently reported. Subconjunctival injection is an alternative that avoids these risks. This retrospective study compares two groups of patients that underwent extracapsular cataract s...

Vascular endothelial growth factor inhibitor is an emerging therapeutic modality for various ocular diseases with neovascularization (NV). However, for corneal NV, controversy remains regarding whether bevacizumab or ranibizumab is superior. A 32-year-old female diagnosed with herpetic keratoconjunctivitis with refractory corneal NV despite two previous subconjunctival and intrastromal bevacizu...

Scleritis commonly is a recurrent disease that requires long term immunosuppressive treatment that can be associated with significant adverse effects. Although topical and periorbital steroids are accepted therapeutic options for treatment of scleritis, subconjunctival administration of depot corticosteroids has been considered unsafe owing to the risk of scleral thinning and perforation. Recen...

Ocular penetration of 5-fluorocytosine (5FC) was studied in uninfected rabbits after subconjunctival and oral administration. With oral administration, 5FC achieved therapeutic levels in both the vitreous and aqueous humors. The use of a pharmacokinetic model permitted objective comparison of kinetic events within the eye chambers and the serum. The rates of entry and elimination in the vitreou...

We report the first case of ocular benign lymphoid hyperplasia (BLH) treated with subconjunctival injection of bevacizumab (Avastin). A 27-year-old man presented to our clinic with conjunctival masses and limbal neovascularization. An incisional biopsy yielded the diagnosis of BLH. The patient was subsequently given a subconjunctival injection of bevacizumab (1.25 mg / 0.1 mL). The patient did ...

THE properties of polymyxin in relation to ocular therapeutics have recently been discussed at some length ; the penetration of this antibiotic into the eye of the rabbit after subconjunctival injection was estimated and the results obtained in the treatment of corneal infection experimentally produced with Ps. pyocyanea have been reported (Ainslie and Smith, 1951). It is well known that this t...

PURPOSE To quantify fibrin degradation products after topical and subconjunctival administration of recombinant tissue plasminogen activator in rabbits. METHODS Fibrin formation was induced in the anterior chamber in 25 rabbits. Subsequently, five rabbits received an injection of r-TPA (positive control) in the anterior chamber, another 10 received a subconjunctival injection of r-TPA, and th...
