Topical and systemic FFP treatment and conjunctival membrane excision may help rapid rehabilitation and prevent recurrence in cases with ligneous conjunctivitis.
ABSTRACT.Purpose: To determine the haemodynamics of the ciliary choroidal system in diabetics with or without systemic hypertension. Methods: 90 eyes of 45 diabetic patients were included into the study. Patients were divided into two groups based on the presence of systemic hypertension. The pulsatile component of the total ocular blood flow in diabetics with or without hypertension was analyzed using ocular blood flow tonograph (OBF Labs, UK). The control group was comprised of 40 age-matched eyes of 20 volunteers with no ocular or systemic disease. Results were compared with the control group. Results: Pulse amplitude (PA), pulse volume (PV) and pulsatile ocular blood flow (POBF) were significantly lower (p∞0.05) in diabetics without systemic hypertension than the controls. In diabetics with hypertension, although the systolic and diastolic blood pressures were significantly higher than the control group, there was not any statistically significant difference (pϾ0.05) between PA, PV and POBF results. Conclusion: POBF was found to be lower in diabetics without hypertension compared to the controls. Such a presence of systemic hypertension may increase the choroidal blood flow in diabetics.
The 11.2 version of the OBF tonograph is more accurate than the 8.2 version and measures IOP in a manner that corresponds well to the Goldmann applanation tonometer in the 8-10 mm Hg and 21-29 mm Hg intervals. It corresponds fairly well in the 11-20 mm Hg interval.
ABSTRACT.Purpose: The purpose of this study was to evaluate the ocular pulse amplitude changes in patients with Graves' disease. Methods: The pulse amplitudes of 31 patients with Graves' disease were measured with the OBF-Tonograph (OBF Labs UK). All patients were in the euthyroid phase of the disease. 17 patients (Group I) had no ocular involvement or only mild lid retraction. 14 patients (Group II) had either proptosis and/or extraocular muscle involvement. Only the worst involved eye of each patient was included into the study. Results: There was no statistically significant difference between the two groups among the parameters which might influence the pulse amplitude measurement. The pulse amplitude was statistically significantly lower in Group II than in Group I (2.34∫0.79 and 3.22∫0.94 mmHg respectively, p∞0.013). Conclusion: Pulse amplitude measurements may be an important discrimination and classification parameter for patients with ophthalmic Graves' disease.
In the differential diagnosis of a proptosis with an exudative retinal detachment, although rare, the diagnosis of an orbital echinococcis should be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
