Optic nerve avulsion associated with central retinal artery occlusion following rotational globe injury

Avulsion of the optic nerve head is a rare and severe complication of ocular blunt trauma. Herein, we describe a case of 16-year-old boy, who presented with a rare combination of optic nerve avulsion associated with central retinal artery occlusion, following blunt trauma with a leather ball. This report highlights the potential blinding complication following rotational injury.

A clinical study of effect of oral atenolol on normal intraocular pressure and systemic blood pressure.

Atenolol is a newer betablocker, widely used as an antihypertensive drug. It cause a large and rapid fall in IOP when used orally and topically. A total of 33 patients both having normal and raised IOP were included in the study. The drug was given in a dose of 50 mg. tab. orally once a day for 7 days at 8 A.M. and IOP recorded after 24 hours, 72 hours and on 7th day. It produces significant and sustained fall in IOP in both normal and raised IOP patients besides lowering of systematic B.P. and pulse rate. The IOP on patients with systemic hypertension with Atenolol will be reduced and stoppage of therapy may cause glaucoma damage.
