Novel KRIT1/CCM1 mutation in a patient with retinal cavernous hemangioma and cerebral cavernous malformation

Retinal cavernous hemangiomas are rare vascular anomalies, and can be associated with cerebral cavernous malformations (CCM). Distinct mutations have been reported in patients who have both CCMs and retinal cavernous hemangiomas. Fluorescein angiography, spectral domain optical coherence tomography, and genetic testing were performed on a patient with a retinal cavernous hemangioma and a CCM. Our patient was heterozygous in the KRIT1/CCM1 gene for a frameshift mutation, c.1088delC. This would be predicted to result in premature protein termination. We have identified a novel mutation in the KRIT1/CCM1 gene in a patient with both CCM and retinal cavernous hemangioma. We hypothesize that the occurrence of retinal cavernous hemangiomas and CCMs is underlaid by a common mechanism present in the KRIT1/CCM1 gene

Jules Stein, MD Ophthalmologist, Entertainment Magnate, and Advocate for Vision

PurposeTo report the lifetime activities and accomplishments of Jules Stein, MD.DesignRetrospective review.MethodsAssessment of published and unpublished biographical material.ResultsJules Stein combined his love of music and medicine with organizational skills to achieve successive careers as a musician, an ophthalmologist, an entertainment magnate, and an advocate for vision. To preserve vision, he founded Research to Prevent Blindness, founded the Jules Stein Eye Institute at the University of California, Los Angeles, and led a multiyear campaign to establish the National Eye Institute.ConclusionsWith successive careers and extraordinary achievements, Jules Stein created an enduring legacy of benefits to ophthalmology, vision research, and the prevention of blindness

Bilateral Acquired Progressive Retinal Nerve Fiber Layer Myelination

The authors present the multimodal imaging findings of an unusual case of bilateral acquired progressive myelination of the optic disc during a 10-year follow-up period in a hyperopic adolescent patient in the absence of an underlying ocular or systemic abnormality. Myelination of the left optic disc was noted at age 7 and of the right optic disc at age 13, but no other ocular or systemic abnormalities were identified. Cross-sectional optical coherence tomography (OCT) and en face OCT angiography confirmed the presence of myelination of the retinal nerve fiber layer and excluded other etiologic possibilities including an astrocytic hamartoma.

Pilot Study Using Mobile Health to Coordinate the Diabetic Patient, Diabetologist, and Ophthalmologist

In the United States, more than 25 million adults have diabetes, 40% of diabetics have diabetic retinopathy, and diabetes is the leading cause of blindness in people 20 to 74 years of age. Clinical trials have shown that strict control of blood glucose level and other risk factors delays diabetic retinopathy onset, progression, and vision loss. Patients with Type 1 or Type 2 diabetes mellitus, access to an Apple iPhone or iPad, and no psychological or medical condition that would interfere with the study participated in a nonrandomized clinical trial using SightBook™, a free mobile app that enables self-measurement of visual function and creates a password-protected web account for each patient. Sixty patients enrolled in the clinical trial over a 6 month period. Twenty-six participants were men and 34 were women, with ages from 23 to 72 years (mean 45 ± 15) and diabetes duration of 1.5 to 50 years (mean 15.5 ± 11.5). Thirty-nine (65%) patients reported Type 1 diabetes and 21 (35%) patients reported Type 2 diabetes. Every patient established a personal web account on SightBook and invited participation of treating physicians; 51 (85%) patients completed the validated self-reported outcome assessments. Diabetologist examinations of 49 (82%) patients demonstrated systolic hypertension (≥140 mgHg) in 20% and hemoglobin A1c ≥ 7.0% in 56%. Ophthalmology examinations of 45 patients showed visual acuity in the worse-seeing eye of < 20/40 in 18% and diabetic retinopathy in 42% of patients. This clinical trial used a mobile health app to incorporate diabetic patient self-measurement of vision and coordinate the diabetic patient, diabetologist, and ophthalmologist for control of diabetes and diabetic retinopathy risk factors
