“…Our results confirmed the findings of Guthoff et al (1987) that in healthy persons the thickness of the ocular wall is very closely dependent on the axial length of the eye, and that the volume of the wall of the eye is nearly constant (ca. 1.65 cm3).…”

“…The axial length of the eye and the ocular wall thickness were measured on Ultrascan Digital B System IV equipment (Guthoff et al 1987;NCmeth 1989NCmeth , 1990b. On the basis of these data, the volume of the posterior half of the ocular wall was calculated (Guthoff et al 1987;Nemeth 1989). Exact ultrasonographic biometric measurements were performed on 92 eyes of 92 patients.…”

“…The localized alteration in the thickness of the ocular coats is a wellknown ultrasonographic finding (Guthoff 1988;Nover & Grote 1965;Oksala & Varonen 1965;Ossoinig & Cody 1987), but the ophthalmic literature has paid little attention to diffuse-type alterations in the ocular wall. Guthoff et al (1987) demonstrated that the thickness of the coats of the eye is very closely dependent on the axial length of the eye, while the volume of the coats of the eye was thought to be nearly constant.…”

The ocular wall dimensions (thickness and volume) were measured by means of ultrasonography in 61 eyes of 61 patients with different eye diseases and 31 eyes of 31 healthy subjects with or without refractive error. The results confirmed, that in spite of the great variance in the ocular wall thickness, depending on the axial eye length, the volume of the ocular coats is constant in healthy eyes (ca. 1.65 cm3). In patients with ocular hypotony (eyes after intraocular surgery or trauma, and eyes with uveitis or with phthisis bulbi) and in patients with exophthalmus, the ocular wall was thicker and larger in volume than in the healthy control groups. In contrast, the ocular wall dimensions (thickness and volume) were smaller in patients with glaucoma. The results of the study showed that an alteration in the volume of the ocular wall implies a pathological condition of the eye, and thus ultrasound examination of the ocular wall dimensions might play a role in the diagnosis and in the follow-up of the patient.
