Treatment of endophthalmitis after cataract extraction.

Background: A series of 34 patients was prospectively treated for postoperative endophthalmitis according to a specific protocol. The data are from the pilot study performed before initiation of the Endophthalmitis Vitrectomy Study (EVS).

Methods: Patients with bacterial endophthalmitis that developed within 6 weeks of cataract extraction received intravitreal amikacin and vancomycin, subconjunctival and topical antimicrobials and corticosteroids, and systemic corticosteroids.

Relative letter and position difficulty on visual acuity charts from the Early Treatment Diabetic Retinopathy Study.

Ten Sloan letters were used in the visual acuity charts developed for use in the Early Treatment Diabetic Retinopathy Study. We used the data from the 3,710 Early Treatment Diabetic Retinopathy Study subjects to investigate the relative difficulty of the ten Sloan letters and to evaluate whether the position of a letter on a line affected its relative difficulty. In general, our findings were consistent with those of the previous study.

Care of diabetic patients by optometrists in New York State.

Objective: This study was undertaken to learn about the involvement of optometrists in the eye care of diabetic patients in New York and to collect baseline data for planning intervention programs in diabetic eye disease.

Research Design And Methods: This study was conducted by a mail survey being sent to all optometrists in New York whom we could identify through state sources (n = 2270). Three follow-up mailings were conducted.

The care of diabetic patients by ophthalmologists in New York State.

All ophthalmologists in New York State whom the authors could identify through state sources and professional societies (n = 1655) were surveyed about eye care of diabetic patients. Over 90% recommended at least annual retinal examinations for the presented hypothetical patients. Ninety-four percent said they "usually" (31%) or "almost always" (63%) recommend laser treatment for proliferative retinopathy, while 6% said they "occasionally" or "almost never" recommend such treatment.

Vitreous hemorrhage and the Valsalva maneuver in proliferative diabetic retinopathy.

A 59-year-old man with bilateral proliferative diabetic retinopathy underwent fluorescein angiography as a baseline study. Soon after intravenous injection of fluorescein, the patient had an extended episode of vomiting resulting in bilateral vitreous hemorrhages. Photographic evidence is presented that confirms the clinical impression that vitreous hemorrhage may be precipitated by a Valsalva maneuver.
