These results suggest that both scan options give good RNFL thickness measurement reproducibility; the use of the Nerve Head Circle option leads to less interindividual variability and can minimize the effect of differences in optic disc diameter on RNFL thickness measurements in normal subjects.
Both OCT and fundus microperimetry were useful tools for following the favorable course in a case of spontaneous closure of traumatic macular hole in a young patient. During follow-up OCT examinations were able to demonstrate the course of macular hole closure.
Purpose: Retinal photoreceptors layer integrity is considered essential to visual function. We report a case of acute zonal occult outer retinopathy (AZOOR) complex disease (namely AIBSE: acute idiopathic blind spot enlargement) in which apparently a full anatomic regeneration is not needed for a complete functional recovery. Methods: Case report with multimodal imaging. Reports: Visual field recovery in the presence of photoreceptors layer disruption studied by means of Optical Coherence Tomography. Choroid and photoreceptors layer thickness thinned progressively during recovery. Conclusion: This case suggests that anatomical retinal integrity as shown by OCT does not always correspond to visual function. Our case highlights that a complete visual recovery can occur even when structural abnormalities are still observable.
Acute idiopathic blind spot enlargement (AIBSE) is often caused by Acute Zonal Occult Outer Retinopathy (AZOOR), an outer retinal disease. We report two illustrative cases of AZOOR. The first one was a 21-year-old white female who presented with a scotoma and "shimmering lights" in her left eye. In the second case, a 73-year-old white female was referred for evaluation of a "bitemporal hemianopsia" that started years prior, with no clinical significant photopsias. To our knowledge, case two is the longest documented duration of bilateral, progressive, and chronic, idiopathic, enlargement of the blind spot (CIBSE) documented in the English language ophthalmic literature.
A 56-year-old lady was referred for complete binasal hemianopia noticed during routine glaucoma screening. On examination the patient was asymptomatic, there were no ophthalmic causes explaining her visual field defect and further neurologic investigation was normal. Binasal hemianopia is an uncommon finding that is usually associated to intraocular conditions, but may rarely be caused by neurologic diseases. The Authors also review the current ophthalmic literature about binasal hemianopia in patients with otherwise complete neurologic and ophthalmic investigation (idiopathic binasal hemianopia).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
