Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA prospective randomized trial of topical soluble 0.1% indomethacin versus 0.1% diclofenac versus placebo for the control of pain following excimer laser photorefractive keratectomy.
To compare the safety and efficacy of topical nonsteroidal antiinflammatory drugs (NSAIDs) for the control of pain after excimer laser photorefractive keratectomy (PRK). ⋯ Topical 0.1% indomethacin solution helps control the pain induced by excimer laser photoablation of the cornea without any detrimental effect to the corneal epithelial wound healing.

Case ReportsIsolated posterior capsule rupture in blunt trauma: pathogenesis and management.
Although blunt ocular trauma frequently-damages the crystalline lens, isolated rupture of the posterior capsule is an infrequently reported occurrence. The authors describe three patients with this unusual presentation. ⋯ All patients achieved good postoperative visual acuity with well-positioned posterior chamber IOLs (in-the-bag in two eyes, sulcus fixated in one eye). Isolated rupture of the posterior capsule in young patients can be safely managed using the limbal approach and implantation of posterior chamber IOLs, is possible.

Case ReportsPenetrating keratoplasty with a valved glaucoma drainage implant for congenital glaucoma and corneal scarring secondary to hydrops.
The simultaneous management of glaucoma and corneal opacification is sometimes required in infants with severe congenital glaucoma if timely visual rehabilitation is to be achieved. A 1-month-old female infant presented with an enlarged, protuberant, opaque cornea in each eye and elevated intraocular pressure. An intrastromal, fluid-filled cleft was noted in both corneas. ⋯ No postoperative overfiltration occurred. The authors conclude that the use of a valved implant should be considered in patients who require urgent simultaneous corneal and glaucoma surgery for severe congenital glaucoma. This combination may improve early postoperative control of aqueous outflow and positively affect long-term graft survival in these difficult cases.

Randomized Controlled Trial Clinical TrialOculocardiac reflex during retinal surgery using peribulbar block and nitrous narcotic anesthesia.
This study was designed to examine the effects of local and general anesthesia on the oculocardiac reflex (OCR) in adults during retinal detachment surgery, with an aim of determining the safest type of anesthesia and on which extraocular muscle traction causes a higher incidence of OCR. ⋯ This study showed that local anesthesia produces less bradycardia and ectopic arrhythmias and, therefore, may be safer and better than general anesthesia for surgeries in which traction of extraocular muscles is required.

Comparative StudyVisual outcome and ocular survival in patients with retinal detachments secondary to open- or closed-globe injuries.
A retrospective study was undertaken to establish predictive clinical features for final visual outcome and ocular survival for patients who have sustained traumatic retinal detachments (RDs). ⋯ The significant predictive factors for final visual outcome in patients with traumatic RD were the initial visual acuity, the location of the wound, the mechanism of injury, and the number of quadrants of RD.
