Thirty normal subjects were tested with the Titmus stereotest varying the binocular Snellen's visual acuity from 20/20 to 20/200. From the 36 possible combinations, a nomogram describing the relationship of binocular variations of Snellen's visual acuity and stereoacuity was constructed. The nomogram provides a useful reference for comparing expected and… (More)
Paraneoplastic retinopathy appears to represent a nonmetastatic remote effect of carcinoma and is characterized by rapid visual deterioration accompanied by narrow arterioles seen on ophthalmoscopic examination and an extinguished electroretinogram. This syndrome has been described in postmenopausal women, and it is possible that it represents an autoimmune… (More)
A 56-year-old immunocompromised man had an acute decrease in vision that led to the detection of Actinobacillus actinomycetemcomitans endocarditis complicated by septic emboli to his eye and other organs. This case demonstrates that bacterial sepsis can mimic a fungal infection. To our knowledge, this is the first report of endophthalmitis resulting from… (More)
A four-instrument system of 20-gauge, rustproof intraocular forceps can be used in conjunction with pars plana vitrectomy to (1) extract intraocular foreign bodies, (2) manipulate intraocular tissue and a dislocated pseudophakos, and (3) obtain biopsy specimens of vitreous gel and abnormal preretinal and epiretinal membranes. The forceps can also be used as… (More)
The authors designed an intraocular needleholder to grasp the needle of 8-0 or 9-0 sutures during transvitreal procedures to suture the edge of certain giant retinal tears to the eyewall. The instrument uses a guillotine action and has a barrel handle design. There is 135 degrees of angulation between the jaws and the long axis of the instrument. With this… (More)
A new lightweight, low flow infusion/aspiration coaxial cannulated handpiece incorporates novel features which facilitate extracapsular techniques. It functions well when used with either manual or mechanized systems.
The development of a new manual 20-gauge intraocular scissors provides several distinct advantages over prior models. They are compatible with standard vitrectomy systems and useful in applications in both the anterior and posterior segments of the eye particularly for resection of epiretinal and pupillary membranes.
