摘要:
Background.Juxtapapillary capillary hemangioblastomas are vascular lesions that occur on the optic nerve head or immediately adjacent to the optic disc. Although juxtapapillary capillary hemangioblastomas may appear as an isolated clinical finding, they are more likely to be a precursor to the diagnosis of von Hippel-Lindau (VHL) disease. When associated with VHL, the ocular complications from hemangioblastoma are generally greater, and subsequently the prognosis is poorer than for isolated entities.Case Report.A 67-year-old white male presented to our clinic complaining of decreased vision in both eyes at distance and near. A dilated fundus examination revealed a swollen left optic nerve. Visual field testing revealed an inferior arcuate defect in the left eye. Laboratory and radiological testing were normal. Fluorescein angiography showed filling during the retinal arterial phase with late diffuse leakage. Based on these results, a diagnosis of juxtapapillary capillary hemangioblastoma was made. This was later confirmed when fundus photographs taken 7 years earlier were obtained, revealing a stable appearance to the nerve.Conclusion.Potential ocular complications of juxtapapillary capillary hemangioblastomas include vision loss secondary to subretinal and intraretinal fluid, as well as epi-retinal membrane formation and, rarely, exudative retinal detachment. Management ranges from observation to surgical intervention, although definitive treatment guidelines have yet to be established. In addition, it is important for the eye care practitioner to be aware of the association with VHL disease, so that patients may be appropriately referred and managed for other possible systemic complications of the disease.

摘要:
Background.Optometrists often encounter patients with ocular signs and/or symptoms suggestive of carotid artery disease, but criteria for eye care practitioners concerning when to order carotid studies are not well established. A retrospective study in an optometry clinic was performed to determine if certain ocular findings and associated systemic risk factors were associated with hemodynamically significant carotid artery stenosis (HSCAS).Methods.A retrospective analysis was performed on all patients examined in the optometry clinic at the Sepulveda Ambulatory Care Center from January 1, 1998 through December 31, 1999 to identify all patients who had carotid studies ordered. Charts were then reviewed to determine the ocular finding that prompted the carotid study. Statistical analysis using an odds-ratio was performed to determine whether any ocular sign/symptom or systemic risk factor was associated with HSCAS.Results.Of 3822 patients, 48 (1.26%) had carotid studies ordered. Eight (17%) had HSCAS of >50% and symptomatic patients were 1.6 times more likely to have HSCAS than asymptomatic patients. Patients with HSCAS were 1.8 times more likely to have retinal vascular occlusions, 1.9 times more likely to have normotensive glaucoma, 2.4 times more likely to have peripheral retinal hemorrhages, and 2.6 times more likely to be smokers, although none of these factors were found to be a statistically significant indicator of HSCAS. However, the number of systemic diseases tended to be greater for the HSCAS patients compared with the non-HSCAS patients (HSCAS median = 3.5 and the non-HSCAS median = 2, p = 0.049).Conclusion.Although no single ocular or systemic risk factor was found to be a statistically significant indicator of HSCAS, the number of systemic disease risk factors tended to be greater for the HSCAS patients compared with the non-HSCAS patients (p = 0.049). An extensive literature review was also performed to help establish guidelines for when to order carotid studies on the basis of ocular signs and/or symptoms as well as the presence of additive associated systemic risk factors.

摘要:
Purpose.The purpose of this study was to compare the agreement within and between examiners when evaluating real-time and digital photographs of TearScope Plus tear film interference patterns. We also evaluated between-examiner agreement of noninvasive digital tear break-up time (NITBUT) using the TearScope, the relation between NITBUT and tear film interference patterns, and the relation between NITBUT and tear break-up time (TBUT).Methods.Forty nondry eye patients were seen for digital imaging of the tear film using the TearScope Plus mounted on a slit-lamp with the EyeCap Ophthalmic Image Capture System. Two independent examiners first assessed the tear interference pattern in real-time and then captured the patterns and NITBUT digitally for a period of approximately 60 s. Each image series was later graded for interference pattern and NITBUT by the two independent, masked examiners.Results.Within-examiner comparisons of real-time and digital tear pattern photograph grading showed moderate to substantial agreement for experienced examiners (kappa for examiner 1 = 0.76 and kappa for examiner 2 = 0.55). Between-examiner agreement when grading tear patterns was also substantial in real-time (kappa = 0.72) and moderate when using digital photography (kappa = 0.59). The between-examiner mean NITBUT was 11.2 ± 6.8 s and the 95% limits of agreement between examiners were −19.2 to +9.2 s. The mean TBUT was 7.6 ± 10.4 s, and it was on average 3.7 ± 12.0 s shorter than NITBUT (p = 0.06). Thicker tear film interference patterns graded photographically were associated with longer NITBUTs for both examiners (p = 0.001).Conclusions.There is moderate to substantial within- and between-examiner agreement when comparing real-time and digital tear interference patterns photographs when using the TearScope. Although there is considerable between-examiner variability with the NITBUT test, the thicker lipid layer tear patterns tend to be associated with longer NITBUTs.

摘要:
Purpose.The Howell phoria card, a new modification of the Prentice design, has no previously published validity or reliability data. The purpose of this study was to compare the interexaminer repeatability of the Howell phoria card with established tests.Method.Experienced optometrists measured the near heterophoria of 72 subjects. Heterophoria was measured in a pseudo-random order using five standardized procedures: (1) Howell phoria card continuous presentation, (2) Howell phoria card flashed presentation, (3) free-space von Graefe method, 4) Bernell Muscle Imbalance Measure (MIM) card continuous presentation, and (5) MIM card flashed presentation.Results.The von Graefe method and the Howell phoria card flashed presentation found significantly less exophoric results than the MIM card. There was no consistent tendency for different examiners to find more exo- or more esophoric results with the phoria measurement techniques used in this study (p = 0.28). Both the Howell phoria card continuous presentation and the MIM card had significantly less variability in interexaminer differences than the Howell phoria card flashed presentation and the von Graefe method (p < 0.05).Conclusions.Results from this study suggest that the Howell phoria card used in a continuous presentation method has an interexaminer repeatability that is not significantly different from the MIM card but greater than the von Graefe method.
