Randomized Controlled Trial Comparative Study Clinical Trial
Efficacy of diclofenac versus dexamethasone for treatment after strabismus surgery.
To compare the efficacy of topical diclofenac sodium 0.1% versus dexamethasone 0.1% on the conjunctival healing process and on intraocular pressure (IOP) after strabismus surgery. ⋯ Topical diclofenac is superior to dexamethasone for each of the five postoperative parameters examined. Its maximal effect occurred at 2 weeks after surgery, without an increase in IOP or in local subconjunctival hemorrhage.

Comparative Study
Management of alkali burns : an 11-year retrospective review.
To review the spectrum of patients with alkali burns admitted over an 11-year period and to assess the clinical outcomes after the introduction of a standard alkali burn treatment protocol. ⋯ On the basis of our findings, a number of recommendations can be made for the management of alkali injuries. Patients with a grade 1 or 2 injury do not require routine admission and do not benefit from the use of intensive treatment with ascorbate and citrate. A trend toward more rapid healing and a better final visual outcome were apparent in grade 3 burns, but our standard protocol made no difference in grade 4 burns.

Comparative Study
Portable pupillography of the swinging flashlight test to detect afferent pupillary defects.
To investigate the ability of a portable, personal computer-driven, pupillometer to record the pupillary response curve during the swinging flashlight test. Also, to determine whether these response curves can be used to identify and quantify relative asymmetry in the pupillary light reflex between eyes in healthy volunteers with simulated afferent pupil defects (APDs) and patients with optic neuropathies. ⋯ Portable, personal-computer driven, electronic, infrared pupillography can record the swinging flashlight test accurately and identify large afferent pupillary defects. An affordable, portable, reliable device for identifying relative APDs would be useful in the identification and follow-up of patients with neurogenic vision loss.
