“…With the help of fundus-controlled perimetry, targets can be presented via a scanning laser ophthalmoscope or fundus camera directly onto the retina under observation of the examiner. [30][31][32] However, the examination area is comparatively small (Ͻ20°radius), especially with a scanning laser ophthalmoscope, and thus this technique is not able to detect changes within the nasal step region. Glaucomatous alteration of the retinal nerve fiber layer does not exclusively affect just the morphologically visible area but predominantly affects more peripheral regions, corresponding to the course of the nerve fibers.…”

To compare detection rates of glaucomatous visual field defects (VFDs) between the conventional 6°ϫ 6°stimulus grid and locally condensed target arrangements in morphologically suspicious regions. Methods: A total of 66 eyes of 66 patients with glaucoma or patients suspected of having glaucoma (34 females and 32 males; age range, 14-85 years) were enrolled in this study. Individual, local target condensation was realized by fundus-oriented perimetry (FOP) using a campimeter and compared with the results of conventional automated perimetry (CAP), obtained with the Humphrey Field Analyzer (30-2 grid). Results: Twenty-three of the 66 patients showed normal findings with both methods; 27 had concordantly pathological results. In 15 patients we obtained normal findings with CAP, whereas FOP revealed early glaucomatous VFDs. Only one patient showed VFDs with CAP, whereas FOP results were normal. Scotoma detection rates significantly differed between the 2 methods (PϽ.001, sign test). Test duration with FOP was more than doubled compared with CAP. When considering only FOP points coinciding with the 6°spacing of the 30-2 grid, there was no longer a significant difference between FOP and CAP (PϾ.25, sign test). This indicated that the target pattern, rather than the perimetric device, was most relevant for detecting glaucomatous VFDs. Follow-up throughout a series of 3 subsequent sessions at 6-month intervals revealed repeatable results in more than two thirds of all eyes for both FOP and CAP. Conclusions: Fundus-oriented perimetry that uses individually condensed test grids significantly increases the detection rate of glaucomatous VFDs in morphologically conspicuous areas compared with CAP using equidistant (6°ϫ6°) target arrangements. Repeatability is comparable between both methods.

“…Early approaches based on direct ophthalmoscopy or direct slit-lamp ophthalmoscopy were highly examiner dependent and allowed only photopic testing due to high levels of light necessary for retinal illumination [1][2][3][4][5] . Today, using infrared light and scanning laser ophthalmoscopy (SLO), it has become possible to reduce the background illumination for FCP to a degree which has opened the door for a topographic point-by-point assessment of scotopic function [6][7][8] .…”

Purpose: To assess the intrasession test-retest reliability of scotopic cyan and scotopic red fundus-controlled perimetry (FCP) in normal subjects using a modified MAIA “microperimeter” (macular integrity assessment) device. Methods: Forty-seven normal eyes of 30 subjects (aged 33.8 years) underwent duplicate mesopic (achromatic stimuli, 400-800 nm), scotopic cyan (505 nm), and scotopic red (627 nm) FCP, using a grid of 49 stimuli over 14° of the central retina. Test-retest reliability for pointwise sensitivity (PWS), stability of fixation, reaction time and test duration were analyzed using mixed-effects models. Results: PWS test-retest reliability was good among all 3 types of retinal sensitivity assessments (coefficient of repeatability of 4.75 dB for mesopic, 5.26 dB for scotopic cyan, and 4.06 dB for scotopic red testing). While the mean sensitivity decreased with eccentricity for both mesopic and scotopic red testing, it was highest at 7° eccentricity for the scotopic cyan assessment (p < 0.001). Conclusions: The modified MAIA device allows for reliable scotopic FCP in normal subjects. Our findings suggest that testing of scotopic cyan sensitivity largely reflects rod function.

“…More recently, activity was spurred by a paper by Awaya in 1972. Others, all Japanese, participated in early development (Inatomi, 1977;1979;Isayama and Tagami, 1977;Kani and Ogita, 1979;Kani et al, 1977;Ohta et al, 1979Ohta et al, , 1981. Kani and Ohta and their co-workers are among the leaders in this area of endeavor.…”

Perimetry is clearly in an explosive stage of development. Here, an attempt is made to bring together major developments and put them into an orderly perspective. The projection-bowl-perimeters of Bern and Tübingen set the stage. Standardization provides the base for future development and data exchange. Automation and inclusion of computational procedures enhance the possibility of broad utilization for better screening and advanced testing. New test procedures make possible extremely fine localization of functions and allow superior definition of areas of involvement in pathology. New fundus perimeters make possible instantaneous fine correlations between functional changes and observed retinal anatomic lesions.
