Atropine-induced lens extrusion in an open eye surgery

PEDIATRIC ANESTHESIA, Issue 1 2006
ANJOLIE CHHABRA MD
Summary A 2-month-old male baby undergoing penetrating keratoplasty (PKP) under general anesthesia developed bradycardia and a decrease in heart rate to 53 b·min,1 when stay sutures were taken through the superior and inferior rectii. A bolus of 0.1 mg intravenous atropine resulted in tachycardia of up to 180,220 b·min,1, which persisted for 35 min. After corneal trephination was performed the eyeball seemed to pulsate with the heartbeat. Spontaneous extrusion of the lens and vitreous occurred, which necessitated a lensectomy and vitrectomy in addition to PKP. The role of atropine in corneal transplant surgery is discussed here.

Photographic documentation of spontaneous extrusion of a subconjunctival cysticercus cyst

CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 5 2002
Usha Kaul Raina FRCOphth
Abstract Spontaneous extrusion of a subconjunctival cysticercus cyst is a rare occurrence. The case reported is of a 20-year-old man who presented with a subconjunctival cysticercus cyst that was suspected to be undergoing spontaneous extrusion. The eye was photographed as the parasite extruded through the conjunctival opening with undulating movements over 3,4 min. [source]

Effects of Ciprofloxacin-Dexamethasone on Myringotomy Wound Healing,

THE LARYNGOSCOPE, Issue 3 2007
Patricia A. Hebda PhD
Abstract Objective: To evaluate the effects of the ciprofloxacin-dexamethasone (CDX) combination ototopical treatment after myringotomy on tympanic membrane (TM) healing in ears with eustachian tube obstruction (ETO) and unobstructed ears. Study Design: Prospective, randomized, masked, controlled. Methods: ETO was created in the left ear of 30 rats to induce a model of otitis media with effusion (OME). After 3 weeks, bilateral myringotomy was performed (day 0). Animals were randomized into three groups to receive no treatment or bilateral once daily ototopical treatment with balanced salt solution (BSS, vehicle) or CDX for 13 days. Bilateral otomicroscopy was performed on days 7, 14, and 28. On day 14, five randomly selected animals per group were humanely euthanized and the TM harvested for histology. Three additional rats provided normal negative control ears for histologic comparisons. Results: On day 14, TM perforation healing rates were 100% in all ears of untreated and BSS-treated animals, 89% (8/9) in CDX-treated obstructed ears, and 30% (3/10) in CDX-treated unobstructed ears (P < .05 vs. BSS). On day 28, 100% (5/5) of the CDX-treated unobstructed ears and 80% (4/5) of the CDX-treated obstructed ears were healed. Histology showed initial TM thickening postmyringotomy in all ears but no significant qualitative differences between groups on day 28. Conclusion: Myringotomy healing was transiently modulated by treatment with CDX but proceeded normally after CDX discontinuation. This early modulation might enhance middle ear drainage and middle ear concentrations of CDX when tympanostomy tube surgery is performed in patients with active OME and ETO, thus potentially reducing otorrhea and preventing or treating infection. It would not be expected to increase the risk of premature tube extrusion or adversely affect normal healing of the TM after usual spontaneous extrusion. [source]
