Humphrey Field Analyzer

Visual field testing is an important tool in the diagnosis and management of glaucoma.
It is used to confirm that:

• Glaucoma has affected the visual function
• To evaluate the severity of the disease 
• Monitor progression of the disease

The Humphrey Field Analyzer is a wheelchair accessible, diagnostic tool used to examine a patient's visual field. It is the recognized standard of care for early diagnosis and management of ocular diseases resulting in visual field loss.

Why we use the Humphrey Field Analyzer:

• The Humphrey Field Analyzer has been shown to be extremely accurate
• Early Glaucoma Detection: this technology has been shown to provide earlier detection of vision loss due to glaucoma 
• The Humphrey Field Analyzer measures visual fields in as little as two minutes

PeriData

This specialized software allows us to statistically interpret data from the visual field analyzer.

Visual field testing (VFT) and analysis with PeriData software allows Dr. Benjamin to utilize unique statistical methods for analyzing the visual field performance in patients with glaucoma.

Why we use PeriData:

• Transmission of data from the perimeter to the program PeriData
• Visualization by informative graphics and analysis, which helps patients understanding of their diagnosis, treatment and outcome 
• Integration into our electronic medical records
• Colored maps help with defect recognition
• Intelligent statistical analysis helps us to distinguish normal and pathological visual fields, stable courses, and negative trends

The Ocular Blood Flow Analyzer

Ocular blood flow analysis records valuable information about the dynamics of the eye's vascular network.  With this data, we can detect new cases earlier and improve our ability to monitor and manage our current glaucoma patients.

Why we use Ocular Flow Analyzer:

• The OBFA assists in the management and detection of other circulatory abnormalities involving diabetes, retinal and carotid disorders.
• Measures ocular blow flow, as well as intraocular pressure, giving a measurable indication of the vascular health of the eye and is helpful with fitting contact lenses and calculating intraocular lens power for cataract surgery.
• Allows us to evaluate your ocular blood flow and thus predict your lifetime risk of developing glaucoma.
• Fast and comprehensive, the Ocular Blood Flow Analyzer provides highly accurate and sensitive measurements

The Heidelberg Retina Tomograph (HRT)

The Heidelberg Retina Tomograph is an advanced diagnostic tool that can detect glaucoma at its earliest stages: up to 8 years earlier than visual fields or photos.

Why we use the Heidelberg Retina Tomograph:

• Study results have confirmed the HRT provides consistent data leading to precise diagnosis of glaucoma
• HRT not only identifies those patients at high risk for developing glaucoma; it can also identify those at low risk with a greater than 90% accuracy at initial assessment. 
• The HRT can accurately differentiate between normal eyes and early glaucoma indication, before any vision loss has occurred
• The three-dimensional analysis by laser scanning tomography has been shown to be superior to all other imaging technologies
• Because of its advantages, this technology is now generally accepted and used to provide the best service possible for glaucoma patients and patients at risk
• The HRT uses a special laser to take three-dimensional photographs of the optic nerve and the surrounding retina

This laser, which is not powerful enough to harm the eye, is first focused on the surface of the optic nerve and captures the image.  It is then focused on the layer just below the surface and captures that image.  The HRT continues to take images of deeper and deeper layers until the desired depth has been reached.  Finally, the instrument takes all these pictures of the layers and puts them together to form a three-dimensional image of the entire optic nerve.
