“…So far, it is not proved whether those watershed zones which were observed in monkey eyes also exist in human eyes, with the exception of a vertical line dividing the nasal and the temporal regions observed by several investigators [26][27][28][29][30][31], In the present study we have shown that there exists a hori zontal division, running through the fovea and the papilla, in the early filling phase of the choroid. Two angiograms of type II and eight angiograms of type III show this divi sion, which must be interpreted as a wa tershed zone between the short posterior cil iary arteries supplying the upper and lower half of the fovea.…”

“…[26] and Archer et al [27] initially reported that a patchy filling was seen in fluorescein angiograms. Evans et al [28], Oosterhuis et al [29], Shimizu et al [30] and cle Laey [31] observed the early cho roidal filling patterns in the eyes of normal human subjects with fluorescein angiogra phy, and concluded that the so-called defec tive dye filling of the choroid was a regular and physiological phenomenon.…”

Indocyanine green angiograms of the macular region in 40 human eyes were evaluated in order to demonstrate the characteristics of the circulatory patterns of the submacular choroid. During both the early and the late phases of choroidal fluorescence nonuniform fluorescence was found. This implies the existence of watershed zones between choroidal arteries and between choroidal veins. A horizontal line running through the fovea was found to form a boundary between arterial systems, and also, in the majority of cases, between venous system.

“…In contrast to other forms of choroidal atrophy described by these authors, an oedematous zone surrounding the lesion could be observed here, and familial occurrence could not be demonstrated. Maumenee (1970) and Hyvarinen et al (1969) postulated an inflammatory genesis, and they argued their view, among other things, with data obtained by fluorescence angiography. These authors list the following names for this pathological condition: geographic choroiditis and serpiginous (helicoid, geographic).choroidopathy.…”

“…5,6 Each method has limitations in its range of flow velocity or in its area of measurement, and none of them allows measurement in one selected vessel such as the feeder vessels of choroidal neovascularization (CNV). We have developed a system for measuring the blood flow velocity in the retinal artery using fluorescein videoangiography (v-FA) obtained by the use of a scanning laser ophthalmoscope (SLO) and dye dilution techniques.…”

Purpose:To measure the blood flow velocities in feeder vessels of patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration. Methods:We examined the early images of indocyanine green videoangiography (v-ICGA) in 29 patients (29 eyes) with CNV, in whom feeder vessels could be identified by v-ICGA. The v-ICGA images were installed in a personal computer. With original software, optical density measurements were performed for the determination of dye-dilution curves. The flow velocity in a CNV feeder vessel was obtained by analyzing the dye-dilution curves. Results:The mean flow velocity in feeder vessels was 33.8 Ϯ 32.5 mm/s. The flow velocity in feeder vessels of CNV with a diameter of 1.5 mm or larger was significantly higher than that in feeder vessels of CNV with a diameter smaller than 1.5 mm ( P Ͻ .05, unpaired t -test). Conclusions:The flow velocity in CNV feeder vessels can be measured with v-ICGA and a computer-based image analysis system. This system would be useful in the evaluation of choroidal circulation.
