Perilimbal Anesthesia for Pars Plana Vitrectomy
American Journal of Ophthalmology, 1994We attempted to determine the efficacy of perilimbal anesthesia with Monitored Anesthesia Care (intravenous sedation with monitoring of the patients' vital signs by anesthesia) in patients undergoing pars plana vitrectomy. We selected 15 patients who were screened for any physical condition that would preclude them from lying supine and motionless for ...

WOUND COMPLICATIONS IN PARS PLANA VITRECTOMY
RETINA, 1993Eighteen eyes with examples of clinically important wound-related complications are reported. These include hemorrhage, fibrous ingrowth, and tractional or mechanical problems. Wound hemorrhages may occur early or late and can be the cause of substantial morbidity. Furthermore, intraocular blood is undesirable because it may provoke cataract formation,

Temperature control during pars plana vitrectomy
Graefe's Archive for Clinical and Experimental OphthalmologyTo evaluate the impact of temperature-controlled pars plana vitrectomy (PPV) on structural and functional outcomes in a rabbit eye model in vivo.Ten healthy New Zealand White rabbits underwent temperature-controlled PPV in the right eye (group A), using a device specifically designed to heat the infusion fluid/air and integrated into the vitrectomy ...

PARS PLANA VITRECTOMY FOR ASTEROID HYALOSIS
Retina, 1981Asteroid hyalosis is a common, usually asymptomatic, benign vitreous disease affecting older individuals. A case report of an aphakic patient who developed anterior segment complications with no visualization of the fundus is presented.

Pars plana vitrectomy. Microsurgical pars plana lensectomy.
Transactions. Section on Ophthalmology. American Academy of Ophthalmology and Otolaryngology, 1976Pars plana lensectomy, wherein the entire lens within the pupillary area (the anterior capsule, anterior cortex, nucleus, posterior cortex, and posterior capsule) is removed, is now a well-established technique. It is to be considered as a method of choice for the removal of presenile cataracts in patients under the age of 40, developmental cataracts ...

Pars plana vitrectomy. Vitrectomy in diabetic retinopathy.
Transactions. Section on Ophthalmology. American Academy of Ophthalmology and Otolaryngology, 1976In spite of the rather high rate of complications, it is clear that in selected cases of proliferative diabetic retinopathy with massive long-standing vitreous hemorrhage, significant improvement can be accomplished by pars plana vitrectomy. However, the number of eyes recovering 20/40 vision or better remains small (7% in our series at 9 to 15 months ...

Pars plana vitrectomy entry sites.
Transactions of the ophthalmological societies of the United Kingdom, 1983The histological features of vitrectomy entry sites were studied in a group of monkeys following pars plana vitrectomy for experimental posterior penetrating injury. The extent of fibrocellular proliferation and vitreo-retinal complications arising from the vitrectomy wounds were compared to the proliferation from a much larger penetrating trauma site ...
