Comparison of pain, motility, and preoperative sedation in cataract phacoemulsification patients receiving peribulbar or sub-Tenon's anesthesia.

BACKGROUND AND OBJECTIVES: The authors hoped to reduce the need for preoperative sedation and intravenous pain medication during cataract surgery by converting from peribulbar anesthesia to sub-Tenon's anesthesia. PATIENTS AND METHODS: A consecutive series of 2453 cataract patients' charts were reviewed. Each patient had previously watched a videotape explaining the anesthetic method to be used. Requests for preoperative sedation were compared between patients who received peribulbar or sub-Tenon's anesthesia. A sample of 200 charts of nonsedated patients were reviewed to compare intraoperative pain and motility. RESULTS: Intraoperative freedom from pain was reported by 91% of the peribulbar patients and 99% of the sub-Tenon's patients. Preoperative sedation was reduced from 26% of the peribulbar patients to 6.7% of the sub-Tenon's patients. CONCLUSIONS: Sub-Tenon's anesthesia provided excellent intraoperative pain relief and reduced the need for preoperative sedation, making it a satisfactory anesthetic technique for patients undergoing cataract phacoemulsification in an ambulatory surgery facility.

Chromograms of color normals and multiple sclerosis patients.

The Gunkel chromograph was tested on 81 volunteers with normal color vision as indicated by screening with Ishihara plates and the panel D-15. Most of these color normals located their neutral area superior to the geometric center of the chromogram. A minority located their neutral area at the geometric center. Recognition of this variation may prevent misdiagnosis of chromographs of patients suspected of having color vision defects. All 29 eyes with history and VEP findings consistent with optic nerve demyelinization had enlargement of the neutral area, even though visual acuity could be corrected to 20/20.

Use of 14C-antipyrine for estimation of rhesus monkey eye blood flow.

The 14C-antipyrine content of rhesus monkey ocular and brain tissues are demonstrated to be stable between 10 and 60 seconds following infection of this diffusible compound, permitting the estimation of blood flow by the indicator-fractionation technique. Blood flow values for central nervous system (CNS) gray and white matter, optic nerve, and retina were similar to values previously obtained for primates by other blood flow techniques.

The pupil dark response in normal volunteers.

A new semi-automatic videopupillometer with a two-channel video integrator uses prismatic displacement of pupil images for binocular recording with a single infrared-sensitive video camera. The video integrator graphically records pupil area or diameter during testing and can reanalyze and plot information from videotape recordings of pupil responses. This new pupillometer was used to evaluate the pupil dark response in 178 eyes of 89 normal human volunteers (ages 18-75 years). The time course of pupil dilation was similar in volunteers of all ages, even though the average pupil area became progressively smaller with increasing age.

The pupil dark response in narcolepsy.

The pupil dark response and maintenance of pupil area in darkness were compared in seven narcoleptic patients and 14 age-matched normal volunteers. Onset and degree of miosis after maximal pupil dilation in darkness were similar in the two groups, although three narcoleptic patients and no normal volunteers fell asleep during the experiment. The results of this study contradict earlier suggestions that pupillography can be used to distinguish normal individuals in family studies of narcoleptic patients.
