Depth measurement with the slit-lamp microscope.
نویسنده
چکیده
The sagittal distance of ocular structures can be obtained with a slit-lamp microscope providing the movement of the slit-lamp can be measured. A simple device consisting of a pointer attached by a spring clip to the axle of a Haag-Streit 900 slit-lamp is described. The pointer rides over a scale which slides with the slit-lamp. Comparisons of anterior chamber depth and lens thickness showed a high correlation between this optical method and ultrasound measurements.

Slit-lamp measurement of the anterior chamber depth.
A technique is proposed which allows assessment of the anterior chamber depth with a standard table slit-lamp without any extra attachments. A final approximation is made which suggests that a 1 degree change in the angle between the observation and illumination systems of the slit lamp when the end point is reached indicates a change in anterior chamber depth of 0.1 mm.
متن کاملUse of Fourier-Domain Optical Coherence Tomography to Evaluate Anterior Stromal Opacities in Donor Corneas
Purpose. To evaluate Fourier-domain optical coherence tomography (FD-OCT) as an adjunct to traditional slit lamp examination of donor corneas with suspected Anterior Stromal Opacities. Methods. Seven corneas suspected of having anterior stromal opacities by slit lamp examination were evaluated with FD-OCT. Each cornea was evaluated to confirm the presence of opacity and, if present, the depth o...
متن کاملUse of a slit-lamp microscope for treating impacted facial foreign bodies in the emergency department
Identifying, locating, diagnosing, and treating small foreign bodies (FBs) in soft tissues is a challenge for emergency physicians in the emergency department. Additionally, potential complications owing to the remnant FBs are medico-legally significant. The efficacy of conventional imaging methods such as radiography, computed tomography, and ultrasonography are largely limited in visualizing ...
متن کاملTwo-position measurement of intraocular pressure by PT100 noncontact tonometry in comparison with Goldmann tonometry
BACKGROUND The purpose of this study was to evaluate the precision of intraocular pressure measurements obtained by PT100 noncontact tonometry in a handheld and slit lamp-mounted position in comparison with that of Goldmann applanation tonometry in healthy young adults. METHODS Sixty eyes from 60 subjects (30 men and 30 women) aged 22 ± 1 (range 20-24) years participated in this study. Tripli...
متن کاملA new method of estimating the depth of the anterior chamber.
A new method of estimating the depth of the anterior chamber with an accuracy of approximately 0-1 mm is described. The estimate is made with a conventional Haag-Streit 900 slit lamp without any extra attachments.
