A 7-year-old Afghani girl was referred to the retina clinic of Massachusetts Eye and Ear for a chronic-appearing, macula-off retinal detachment in the left eye. On examination, best-corrected visual acuity was 20/400 in the right eye and 20/800 in the left eye. She had bilateral horizontal nystagmus. Ophthalmoscopy revealed prominent choroidal vessels, chorioretinal atrophy in the macular area, attenuated retinal vasculature, and pale optic discs bilaterally. Spectral domain optical coherence tomography demonstrated atrophy of the choriocapillaris and the retinal pigment epithelium, retinal thinning, and abnormal foveal contour...

Deferoxamine is a commonly used chelating agent for secondary hemochromatosis. We report a rare retinal manifestation of deferoxamine toxicity in a 68-year-old man and provide supporting multimodal imaging and electrophysiology. The patient had iron overload related to transfusion-dependent myelodysplastic syndrome and developed a pseudovitelliform macular lesion related to deferoxamine toxicity. We also describe for the first time the worsening of this maculopathy on deferasirox, an alternative chelating agent...

The polymorphism rs10490924 (A69S) in the age-related maculopathy susceptibility 2 (ARMS2) gene is highly associated with age-related macular degeneration, which is the leading cause of blindness among the elderly population. The ARMS2 gene encodes a putative small (11kDa) protein, which the function and localization of the ARMS2 protein remain under debate. For a better understanding of functional impacts of the A69S mutation, we performed a detailed analysis of the ARMS2 sequence with a broad set of bioinformatics tools...

AIMS/HYPOTHESIS: Diabetic retinopathy is characterised by morphological lesions related to disturbances in retinal blood flow. It has previously been shown that the early development of retinal lesions temporal to the fovea may predict the development of treatment-requiring diabetic maculopathy. The aim of this study was to map accurately the area where lesions could predict progression to vision-threatening retinopathy. METHODS: The predictive value of the location of the earliest red lesions representing haemorrhages and/or microaneurysms was studied by comparing their occurrence in a group of individuals later developing vision-threatening diabetic retinopathy with that in a group matched with respect to diabetes type, age, sex and age of onset of diabetes mellitus who did not develop vision-threatening diabetic retinopathy during a similar observation period...

Age-related macular degeneration (AMD) and related macular dystrophies (MDs) are a major cause of vision loss. However, the mechanisms underlying their progression remain ill-defined. This is partly due to the lack of disease models recapitulating the human pathology. Furthermore, in vivo studies have yielded limited understanding of the role of specific cell types in the eye vs. systemic influences (e.g., serum) on the disease pathology. Here, we use human induced pluripotent stem cell-retinal pigment epithelium (hiPSC-RPE) derived from patients with three dominant MDs, Sorsby's fundus dystrophy (SFD), Doyne honeycomb retinal dystrophy/malattia Leventinese (DHRD), and autosomal dominant radial drusen (ADRD), and demonstrate that dysfunction of RPE cells alone is sufficient for the initiation of sub-RPE lipoproteinaceous deposit (drusen) formation and extracellular matrix (ECM) alteration in these diseases...

PURPOSE: External beam radiation therapy (RT) is an effective palliative treatment for patients with choroidal metastases and is aimed at preserving vision and obtaining local tumor control. Delivery of 30 to 40 Gy in 2-Gy daily fractions is a standard approach at many centers. This study reports the outcomes of a hypofractionated schedule of 20 Gy in 5 fractions in this palliative setting. METHODS AND MATERIALS: We conducted a retrospective review of patients who were treated with RT (20 Gy in 5 fractions) for choroidal metastases between January 1999 and November 2012...

Sustained-release intravitreal 0.7 mg dexamethasone (DEX) implant is approved in Europe for the treatment of macular edema related to diabetic retinopathy, branch retinal vein occlusion, central retinal vein occlusion, and non-infectious uveitis. The implant is formulated in a biodegradable copolymer to release the active ingredient within the vitreous chamber for up to 6 months after an intravitreal injection, allowing a prolonged interval of efficacy between injections with a good safety profile. Various other ocular pathologies with inflammatory etiopathogeneses associated with macular edema have been treated by DEX implant, including neovascular age-related macular degeneration, Irvine-Gass syndrome, vasoproliferative retinal tumors, retinal telangiectasia, Coats' disease, radiation maculopathy, retinitis pigmentosa, and macular edema secondary to scleral buckling and pars plana vitrectomy...

Deafness, kidney disease and diabetes are not a usual association, neither is a family history of these diseases. We present the case of a 47-year-old woman with non-nephrotic proteinuria, no haematuria, normal renal function, sensorineural hearing loss, recently diagnosed diabetes and maculopathy. There was a maternal family history of deafness, diabetes and renal disease. Renal biopsy revealed focal and segmental glomerulosclerosis (FSGS), leading to the pursuit of an m.3243A > G mitochondrial mutation and diagnosis of maternally inherited diabetes and deafness...

Transplantation of rod photoreceptors, derived either from neonatal retinae or pluripotent stem cells (PSCs), can restore rod-mediated visual function in murine models of inherited blindness. However, humans depend more upon cone photoreceptors that are required for daylight, color, and high-acuity vision. Indeed, macular retinopathies involving loss of cones are leading causes of blindness. An essential step for developing stem cell-based therapies for maculopathies is the ability to generate transplantable human cones from renewable sources...

A 6-month-old male infant presented for routine ophthalmologic examination. Indirect ophthalmoscopy revealed a flat, oval, hypopigmented lesion located in the temporal macula in the right eye with the tip pointing toward the fovea, which was compatible with torpedo maculopathy. Optical coherence tomography (OCT) was performed at the time of diagnosis. OCT scans of the lesion revealed slight retinal pigment epithelium hyperreflectivity. This case serves as the earliest OCT finding of the youngest patient diagnosed as having torpedo maculopathy in the literature...
