PURPOSE To evaluate photoreceptor inner/outer segment (IS/OS) defect parameters by using spectral domain-optical coherence tomography (SD-OCT) for correlation with visual outcomes in macular hole surgery (MHS). METHODS This study was an interventional, retrospective case series. Twenty-three eyes (23 patients) were examined by SD-OCT before and after(More)
Acute retinal necrosis (ARN), also known as Kirisawa-type uveitis, is an uncommon condition caused by infection of the retina by one of the herpes family of viruses, most typically varicella zoster virus or herpes simplex virus and less commonly cytomegalovirus. Clinical diagnosis can be challenging and is often aided by PCR-based analysis of ocular fluids.(More)
PURPOSE To measure drusen area and volume in eyes with nonexudative age-related macular degeneration (AMD) using spectral domain optical coherence tomography imaging (SD-OCT). DESIGN Evaluation of diagnostic technology. PARTICIPANTS One hundred three eyes from 74 patients with drusen. METHODS Patients with drusen secondary to nonexudative AMD were(More)
PURPOSE To report successful treatment of exogenous Fusarium and Aspergillus endophthalmitis with new antifungal agents. DESIGN Interventional case report. METHODS Treatment of two cases is reviewed. RESULTS A 64-year-old man developed post-cataract Fusarium moniliforme endophthalmitis. Infection persisted despite removal of the intraocular lens,(More)
PURPOSE To study cone photoreceptor structure and function in patients with inherited retinal degenerations treated with sustained-release ciliary neurotrophic factor (CNTF). METHODS Two patients with retinitis pigmentosa and one with Usher syndrome type 2 who participated in a phase 2 clinical trial received CNTF delivered by an encapsulated cell(More)
PURPOSE To correlate visual function with high-resolution images of retinal structure using adaptive optics scanning laser ophthalmoscopy (AOSLO) in 4 patients with acute zonal occult outer retinopathy (AZOOR). DESIGN Observational case series. METHODS Four women, aged 18 to 51, with acute focal loss of visual field or visual acuity, photopsia, and(More)
PURPOSE To establish adaptive optics scanning laser ophthalmoscopy as a method to detect and characterize microscopic signs of diabetic retinopathy in capillaries and cone photoreceptors in the parafovea. METHODS Recently, adaptive optics scanning laser ophthalmoscope (AOSLO) has enabled noninvasive assessment of photoreceptors, capillaries, and(More)
BACKGROUND AND PURPOSE Functional neuroimaging can distinguish components of the pain experience associated with anticipation to pain from those associated with the experience of pain itself. Anticipation to pain is thought to increase the suffering of chronic pain patients. Inappropriate anxiety, of which anticipation is a component, is also a cause of(More)
PURPOSE Spectral domain optical coherence tomography (SD-OCT) uses infrared light to visualize the reflectivity of structures of differing optical properties within the retina. Despite their presence on histologic studies, traditionally acquired SD-OCT images are unable to delineate the axons of photoreceptor nuclei, Henle's fiber layer (HFL). The authors(More)
PURPOSE To evaluate and characterize multiple evanescent white dot syndrome abnormalities with modern multimodal imaging modalities. METHODS This retrospective cohort study evaluated fundus photography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, enhanced depth imaging optical coherence tomography,(More)
