In a study of 103 eyes, the measurement of intraocular pressure (IOP) was compared between the Perkins hand-held tonometer and the Goldmann slit lamp mounted tonometer. IOP readings from the two instruments were highly correlated (+0.91). Advantages inherent to the Perkins design are also discussed.
The proper diagnosis of ocular emergencies is usually straightforward since the patient generally can communicate the nature and circumstances of the injury. However, the mental status of the patient occasionally may seriously complicate obtaining an accurate history of the trauma. This may be particularly important when the patient has been physically… (More)
Biomicroscopy is an indispensable part of the ocular health examination performed on every patient. The purpose of this paper is to briefly review the basic illumination technique so that the examiner thoroughly understands their uses and develops for himself a specific investigative procedure. This testing may progress from the lids and lashes to the… (More)
Waldenström's macroglobulinemia is a progressive neoplastic syndrome of the reticuloendothelial system and is characterized by the presence of monoclonal IgM paraproteins. The ocular manifestations of macroglobulinemia can include mid-peripheral hemorrhages, sludging of blood in the conjunctival vessels, blurred disc margins, exudates in the fundus and… (More)
This review paper discusses potential relationships between Cholesterol levels, the therapeutic use of Statins and the risk of Alzheimer s Disease. Comparisons have also been made between the Western populations and Oriental populations. Epidemiological studies have shown that statins, which reduce the levels of plasma cholesterol by inhibiting the enzyme 3… (More)
Hemangiomas are benign vascular hamartomas which occur more commonly in women between the ages of 30 and 50 years. These tumors are among the most common lesions found in the adult orbit. The purpose of this report is to describe the usefulness of delayed blood pool scans for diagnosing unusually located hemangiomas as highlighted in our report of a… (More)
Chalazia are commonly encountered lesions of the eyelids. They often resolve spontaneously or respond to a conservative therapeutic regimen. Chalazia not responding to this type of treatment are often referred for surgical extirpation. This article presents an alternative to surgery, namely intralesional injection of a synthetic glucocorticoid. Reports show… (More)
Recurrent, bilateral, and severe conjunctival hemorrhages mandate the search for an underlying etiology, such as a blood dyscrasia, blood clotting disorder, or recurrent increased intrathoracic pressure caused by repetitive vomiting or coughing spells. Medical and ophthalmic management is discussed in a case of subconjunctival and external hemorrhage from… (More)
A patient presenting with a left pupil-sparing oculomotor palsy and periorbital pain was subsequently found to have a giant saccular aneurysm of the right internal carotid artery within the cavernous sinus. The aneurysm was of the contralateral artery compared to the side of all presenting neuro-ophthalmic signs and symptoms. Diagnosis was achieved by… (More)
The measurement of blood pressure, sphygmomanometry, can provide much significant information for the optometrist's evaluation of his patient's ocular and related systemic conditions when the principles involved are understood and skill in its measurement is achieved. This paper will discuss the procedural details of blood pressure measurement.
