Novel device addresses limitations of gonioscopy

Automated gonioscopy is a useful new imaging technique for topographic analysis of the iridocorneal angle, according to Jean-Paul Renard, MD. Speaking at the ESCRS/EGS Glaucoma Day meeting, Dr Renard described the technology, its operation, applications, and limitations. The instrument incorporates a Goldmann goniolens with 16 faceted mirrors. The tip of the lens makes indirect contact with the ocular surface, and the examination is completed in approximately one minute. Dr Renard discussed the use of automated gonioscopy for examining eyes with various forms of secondary glaucoma and as an aid for more precise analysis of angular surgeries. Although it has limitations, which include a necessary learning curve and the impossibility of being used to perform a dynamic examination, automated gonioscopy has many advantages and exciting potential. “This automated device gives us rapid access to data of the angle with precise topographic analysis and allows longitudinal follow-up of all angular illnesses,” said Dr Renard, Paris, France. “We know that more precise and detailed analysis of the angle and the possibility of magnification offer the exciting possibility to study the relationships between angle closure and. More precise analysis of the angular surgery also allows better understanding of its results and adverse events.”
