Randomized Controlled Trial Clinical Trial
A study of topical nonsteroidal anti-inflammatory drops and no pressure patching in the treatment of corneal abrasions. Corneal Abrasion Patching Study Group.
To evaluate the effectiveness of an ophthalmic nonsteroidal anti-inflammatory drug (NSAID) in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions and no pressure patch. ⋯ Ketorolac tromethamine 0.5% ophthalmic solution provides increased patient comfort without clinical adverse effects when used as adjunctive therapy in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions.

Randomized Controlled Trial Clinical Trial
Dilute topical proparacaine for pain relief after photorefractive keratectomy.
The purpose of the study is to determine whether there is a nonanesthetic and nontoxic concentration of topical proparacaine that can be applied repeatedly to the cornea to reduce pain after photorefractive keratectomy (PRK). ⋯ Dilute (0.05%) topical proparacaine is nonanesthetic and nontoxic, and can be used safely for at least 1 week to reduce pain after PRK.

This study describes the magnetic resonance imaging (MRI) anatomy of the blood vessels and nerves of the orbit to provide a morphological basis for the interpretation of clinical findings. ⋯ High-resolution MRI is capable of delineating the orbital arteries, veins, and nerves. This is mainly based on two principles. First, blood vessels appear mostly dark on magnetic resonance images because of the signal void of flowing blood. Second, the bright background of the orbital fat on T1-weighted magnetic resonance images accounts for the good soft-tissue contrast in the orbit. With improved MRI technology and reduced imaging time, high-resolution-MRI may be applied routinely for diagnostic purposes.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of postoperative emesis, recovery profile, and analgesia in pediatric strabismus repair. Rectal acetaminophen versus intravenous fentanyl-droperidol.
Postoperative nausea and vomiting comprise significant morbidity in pediatric patients undergoing strabismus repair and can prolong hospitalization. Many authors recommend routine intraoperative opiate analgesia and prophylactic antiemetics. ⋯ Prophylactic fentanyl-droperidol prolongs the length-to-stay and recovery time and provides no discrete identifiable benefit over acetaminophen alone in this population. Cost-effectiveness analysis strongly favors use of acetaminophen over fentanyl-droperidol prophylaxis in children undergoing primary strabismus surgery.

The efficacy and safety of parabulbar anesthesia was investigated prospectively in 100 patients undergoing primary vitreoretinal surgery. ⋯ Parabulbar anesthesia is a safe and effective technique of local anesthesia in patients undergoing primary vitreoretinal surgery.
