To report the association between bilateral posterior ischemic optic neuropathy and spinal surgery. ⋯ Severe selective hypoperfusion of the retrobulbar optic nerves may occur after spinal surgery. Pressure to the periorbital region may be a contributing factor.

Case Reports
Cataracts, bilateral macular holes, and rhegmatogenous retinal detachment induced by lightning.
To report ocular injuries, including a unilateral rhegmatogenous retinal detachment, induced by lightning. ⋯ This is a case of bilateral cataracts, posterior vitreous detachments, macular holes, and a unilateral retinal detachment associated with lightning. We postulate that the heating of the retinal surface, the concussive forces on the eye, and a sudden lateral contraction of the attached vitreous resulted in bilateral posterior vitreous detachments and a unilateral peripheral retinal break.

To determine whether routine office techniques used to disinfect tonometer prisms and trial contact lenses are sufficient to prevent transmission of ocular infections. ⋯ A safe office environment can be maintained by following current CDC recommendations for disinfection, as well as instituting some additional procedures.

Clinical Trial
Doppler ultrasound of blood flow velocities in ophthalmic and central retinal arteries during the early neonatal period.
To obtain standard values of blood flow velocity in the ophthalmic artery and central retinal artery in the neonatal period and to compare blood flow velocity of orbital vessels with that of the anterior cerebral artery and middle cerebral artery. ⋯ We report blood flow data of the ophthalmic artery and central retinal artery in healthy neonates and suggest that a delay of arterial blood flow changes occurs for the ophthalmic artery and central retinal artery with respect to the anterior cerebral artery and middle cerebral artery in the early prenatal period.
