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.
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)
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)
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 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)
Morgagnian cataract is a hypermature lens in which the cortex liquifies and the dense nucleus sinks inferiorly. Aside from the total reduction of vision, serious sequelae may result. This report is of a unilateral Morgagnian cataract of unknown etiology for which a dilated pupil facilitated the differential diagnosis between cataract types.
Gonioscopy is the ocular health examination technique which offers to the practitioner the means to directly study the anterior chamber angle. Its uses are numerous and include glaucoma classification, predilation angle evaluation, and the presence of iris tumors, foreign bodies and anterior synechiae. Since a meaningful gonioscopic examination depends upon… (More)
Spontaneous hyphema refers to a nontraumatic hemorrhage in the anterior chamber. It is uncommon and may result from such conditions as rubeosis iridis, intraocular neoplasms, blood dyscrasias, severe iritis, fibrovascular membranes in the retrolental or zonular area, and vascular anomalies of the iris. A case is presented describing a spontaneous hyphema… (More)
The carbonic anhydrase inhibitors that are used most frequently in ophthalmic practice are acetazolamide and methazolamide. They both are weak systemic diuretics and lower intraocular pressure ultimately by decreasing aqueous production. Unfortunately, they have a number of important side effects including the potentiation or exacerbation of metabolic… (More)
