    Retinal arterial occlusions may be primarily or secondarily associated with low retinal arterial pressure. Based on previous ophthalmodynamometric studies1–6 the purpose of the present study is to estimate the retinal vessel pressure in patients with central retinal artery or branch retinal artery occlusions and patients with amaurosis fugax.

    Case report

    This prospective clinical non-interventional comparative study included nine eyes of seven patients (mean age 68.8 (SD 13.7) years) with central retinal artery occlusion (n = 1 eye), branch retinal artery occlusion (n = 2), ischaemic ophthalmopathy (n = 2), or amaurosis fugax (n = 4). An age matched control group consisted of 27 eyes of 21 subjects attending the hospital because of cataract or refractive problems. After medical pupil dilatation, a conventional Goldmann contact lens fitted with a pressure sensor mounted into the holding ring was put onto the cornea. By slightly pressing the …
