Current Trends in Treating Acanthamoeba Keratitis: A Brief Narrative Review
The author, after examining the historical evolution of scientific knowledge and treatment of severe Acanthamoebic keratitis, presents this brief review on the treatment of this serious eye disease, relatively frequent in patients with corneal contact lenses. Therapy of Acanthamoeba keratitis is always very long and demanding. Its management requires adequate experience because it is not always easy to evaluate the response to treatment and complications can be very serious and difficult to manage. Resistance to therapy can also occur during treatment and must be distinguished from drug-induced toxicity. In cases where no improvement is obtained with maximum medical therapy, it is advisable to repeat the corneal sampling and proceed to new laboratory tests for Acanthamoeba, bacteria and fungi. Prevention, which always remains of fundamental importance, is practically based on avoiding contact of the corneal lens with contaminated water, since this Acanthamoeba has a ubiquitous diffusion. It is therefore recommended to always avoid the use of corneal contact lenses in the pool or in the shower, not to wash them under running tap water and to frequently replace the relative container of these lenses
Optical coherence tomography angiography versus fluorescein or indocyanine green angiography: legal implications for ophthalmologists
Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique able to show real-time volumetric data on chorioretinal vasculature. The
most commonly used angiographic techniques in visualizing vascular changes are fluorescein (FA) or indocyanine green angiography (ICGA). Dye-based techniques
require intravenous dye injection which can cause side effects. The physician has the responsibility to decide which diagnostic instrument is more appropriate. Legal
implications are due to the side effects of dye injection. OCTA test can be performed without side effect
Ropivacaine vs tetracaine in topical anesthesia for intravitreal injection
Aim: The object of the study was to evaluate the long term efficacy and safety of ropivacaine 0,5% vs tetracaine 0,5% for topical
anesthesia in intravitreal injection
of dexamethasone in patients with diabetic macular edema (DME) and anti-vascular endothelial growth factor (VEGF) therapy.
Methods: Thirty-seven patients were enrolled in the study. Intravitreal anti-vascular endothelial growth factor (VEGF) and
Dexamethasone were placed in DME patients.
Intravitreal administration determines appropriate and long-lasting drug's concentration without systemic side effects. Topical
anesthesia under ropivacaine 0,5% vs tetracaine 0,5% was performed.
Results: Intravitreal injection without any supplemental anesthesia and sedation was realized. Patients reported mild pain
(recorded by a 0 to 10 scale) during the procedure with optimal operative result.
Conclusions: Topical anesthesia with ropivacaine and tetracaine is safe and effective in intravitreal injection. The long-lasting
anesthesia secured low pain during this limited but unpleasant procedure
