High-pass resolution perimetry, or the "ring test," is a recently developed type of acuity perimetry. To determine its test-retest variability, we studied 10 normals and 10 patients with idiopathic intracranial hypertension (IIH) by testing both eyes four separate times. There was no increase in variability from the center out to 21 degrees of visual field(More)
PURPOSE To report the preliminary results of oscillatory photodynamic therapy (OPDT) for choroidal neovascularization (CNV) and central serous retinopathy (CSR). METHODS This study included 7 eyes of 6 patients with CSR (2 eyes), idiopathic CNV (2 eyes), CNV due to age-related macular degeneration (AMD) (2 eyes), and peripapillary CNV secondary to(More)
To determine the sensitivity and specificity of high-pass resolution perimetry ("ring test"), 18 patients with pseudotumor cerebri (PTC) and 18 age-matched controls were examined with the Humphrey program 24-2 and the ring test. Goldmann perimetry also was done to determine if defects found with the ring test were present with another method. Testing with(More)
We used a CW-YAG endolaser to photocoagulate the fundus of the rabbit and monkey. We varied the power settings, exposure durations, and probe-retina distances to establish the parameters for threshold and bursting (choroidal hemorrhage) lesions. We found that the amount of energy needed to create a retinal lesion increased proportionally with the distance(More)
Alzheimer's disease (AD) is an increasingly common disease with massive personal and economic costs. While it has long been known that AD impacts the visual system, there has recently been an increased focus on understanding both pathophysiological mechanisms that may be shared between the eye and brain and how related biomarkers could be useful for AD(More)
OBJECTIVE We investigated the effect of scleral reinforcement on ocular elongation in the rapidly growing eyes of juvenile cats. METHODS Bands made from donor sclera or expanded polytetrafluoroethylene were used to reinforce one eye of each animal; contralateral eyes underwent sham surgery. RESULTS During 5 months of follow-up, normal intraocular(More)
