Purpose: To evaluate the utility of surface rendering of 3D ultrasound images in selected cases of ophthalmic disease using the OTI–Scan 1000 Ultrasound Tomography System. Methods: With the patient supine and topical anesthetic drops administered, 3D B–scan was performed through the lids or directly on the eye using a 12 MHz B–scan probe attached to the OTI–Scan 1000 Ultrasound Tomography System (Ophthalmic Technologies Inc. [OTI], Toronto, Ontario, Canada). Each resulting interactive 3D volume block was surface rendered using the manufacturer’s integrated software. Results: A variety of ophthalmic pathologies were included in the study e.g. retinal and choroidal detachments, retinoblastomas, retinoschisis, myopic globes, lens dislocations, intraocular foreign bodies, choroidal tumors with or without radioactive plaque implantation, ruptured globes. Some adjustment in threshold, depth and texture settings was needed to intensify depth and emphasize fine detail of structures within the 3D volume block. Each surface rendered 3D ultrasound image presented a virtual picture of structures within the scanned area in most cases, revealing details not usually observed with regular 3D ultrasound images. However, 3D ultrasound recordings should be obtained without motion artifacts as these have deleterious effects on the surface rendered image. Conclusions: Surface rendering of 3D ultrasound images using the OTI–Scan 1000 Ultrasound Tomography System is a novel way of imaging ophthalmic pathologies in vivo. It reveals topographic information masked by regular 3D B–scans.
