Bottom Line: Peripheral OCT imaging helped elucidate clinically ambiguous situations such as retinal breaks, subclinical retinal detachment, retinoschisis, choroidal nevus, and metastasis.Limitations of such scanning included end-gaze nystagmus and far peripheral lesions.This first of its kind study demonstrates the feasibility of peripheral retinal OCT imaging and expands the spectrum of indications for which OCT scanning may be clinically useful.

ABSTRACT
Optical coherence tomography (OCT) has transformed macular disease practices. This report describes the use of conventional OCT systems for peripheral retinal imaging. Thirty-six eyes with peripheral retinal pathology underwent imaging with conventional OCT systems. In vivo sectional imaging of lattice degeneration, snail-track degeneration, and paving-stone degeneration was performed. Differences were noted between phenotypes of lattice degeneration. Several findings previously unreported in histopathology studies were encountered. Certain anatomic features were seen that could conceivably explain clinical and intraoperative behavior of peripheral lesions. Peripheral OCT imaging helped elucidate clinically ambiguous situations such as retinal breaks, subclinical retinal detachment, retinoschisis, choroidal nevus, and metastasis. Limitations of such scanning included end-gaze nystagmus and far peripheral lesions. This first of its kind study demonstrates the feasibility of peripheral retinal OCT imaging and expands the spectrum of indications for which OCT scanning may be clinically useful.

Figure 4: Optical coherence tomography image of snail-track degeneration demonstrating thinning with markedly wrinkled inner retinal surface and no vitreoretinal abnormalities

Mentions: Snail-track degeneration (2 eyes) demonstrated irregular thinning with a wrinkled curvilinear inner retinal surface [Fig. 4]. No changes (traction, condensation) were seen in the overlying vitreous. Paving-stone degeneration (2 eyes) demonstrated uniform marked thinning of the retina over the lesion with choroidal hyperreflectivity.
