Comments and Conclusions
- SD OCT in infants, toddlers and patients confined to wheel chairs is possible with the iVue when used as a hand held portable instrument.
- Integrity of the photoreceptors, both rods and cones, can be confirmed or denied based upon the appearance of the PIL.
- Similarly, integrity or lack thereof of the optic nerve can be assessed by analyzing the retinal nerve fiber layer by OCT.
- Based upon the exemplary cases here, congenital medullation of the RNFL appears to be associated with photoreceptor abnormalities.
- Eyes without a PIL will unlikely improve with patching and vision training and hence represent a poor prognosis.
- The iVue, the least expensive of the SD OCTs available to date, is capable of capturing clinically useful OCT images in typical patients with myriad retinal and optic nerve disorders but also in those patients in whom a hand held OCT is required.
