To present an ultrasonographic finding that simulated an intraocular foreign body after repair of a ruptured globe. ⋯ Although a highly reflective echo source in the presence of a ruptured globe may suggest a foreign body, the presence of orbital air should also be considered when interpreting ultrasonograms used in the preoperative and postoperative management of globe trauma.

To determine risk factors for secondary hemorrhage and poor visual outcome in children with traumatic hyphemas. ⋯ Sickle cell trait is a significant risk factor for secondary hemorrhage, increased intraocular pressure, and permanent visual impairment in children who have traumatic hyphemas following blunt trauma.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Cardiovascular effects of topical carteolol hydrochloride and timolol maleate in patients with ocular hypertension and primary open-angle glaucoma. Night Study Group.
To compare the effects of topical timolol maleate 0.5% and carteolol hydrochloride 1% on pulse rate and blood pressure. ⋯ Timolol causes significantly lower mean heart rate during the nighttime and more nocturnal bradycardia than carteolol does in patients with ocular hypertension and primary open-angle glaucoma. These differences may be because of the intrinsic sympathomimetic activity of carteolol.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparative study of the effects of timolol and latanoprost on blood flow velocity of the retrobulbar vessels.
To examine the effects of topical timolol and latanoprost on retrobulbar vessel blood velocity in patients with glaucoma or ocular hypertension. ⋯ Topical timolol and latanoprost significantly reduced the intraocular pressure in ocular hypertensive and glaucoma patients without creating substantial hemodynamic changes in the retrobulbar vessels.

Case Reports
Atlantoaxial dislocation related to instilling eyedrops in a patient with Down's syndrome.
To alert ophthalmologists of the risk of hyperextending the neck of patients with Down's syndrome while holding them to instill eyedrops. ⋯ Examination and clinical maneuvers in a child with Down's syndrome require gentleness and avoidance of hyperextension of the neck to prevent spinal cord injury.
