A comprehensive evaluation of 181 reported variants in patients with macular corneal dystrophy.

Aging (Albany NY) 2019 Feb;11(3):1019-1029

Department of Ophthalmology and Visual Science, Eye Institute, Eye and ENT Hospital, Shanghai Medical College of Fudan University, NHC Key Laboratory of myopia (Fudan University), Shanghai Key Laboratory of Visual Impairment and Restoration, Shanghai, China.

Macular corneal dystrophy (MCD) is an autosomal recessive disease featured by bilateral progressive stromal clouding and loss of vision, consequently necessitating corneal transplantation. Variants in gene have been recognized as the most critical genetic components in MCD. Although many variants have been described until now, the detailed mechanisms underlying MCD are still far from understood. Read More

a Department of Ophthalmology , Moorfields Eye Hospital , London , UK.

Background: Age-related macular degeneration (AMD) is a common sight threatening condition. However, there are a number of monogenic macular dystrophies that are clinically similar to AMD, which can potentially provide pathogenetic insights.

[Progressive loss of vision in cone dystrophy. Search for evidence with macular OCT and multifocal ERG].

Ophthalmologe 2018 Nov 13. Epub 2018 Nov 13.

Klinik für Augenheilkunde, Universitätsklinikum Freiburg, Freiburg, Deutschland.

A 53-year-old patient consulted our practice clinic complaining of progressive visual loss, increased glare sensitivity and color sense disorder. Extensive diagnostic investigation, including multifocal ERG (mfERG) and macular thickness map with the help of optical coherence tomography (OCT), supported the suspected diagnosis of a cone dystrophy. There are, however, no established therapeutic options. Read More

Morphological and functional findings in Alström syndrome: a study of two families.

Arq Bras Oftalmol 2018 Nov./Dec.;81(6):524-528. Epub 2018 Oct 11.

Centro Brasileiro da Visão, Brasília, DF, Brazil.

Alström syndrome is a rare disorder characterized by mutations to the ALMS1 gene and clinical findings of childhood obesity, diabetes mellitus, dilated cardiomyopathy, sensorineural hearing loss, and progressive cone-rod dystrophy, which may result in blindness. Ocular manifestations occur in the first decade of life with nystagmus, blepharospasm, and photophobia leading to progressive and severe reductions in visual acuity. This study describes the retinal structure and functional aspects of four patients (8 eyes) from two different families as determined by optical coherence tomography (OCT), fundus autofluorescence, and full-field electroretinography.

The Stephen A. Wynn Institute for Vision Research, Department of Ophthalmology and Visual Science, Carver College of Medicine, University of Iowa, Iowa City, Iowa.

Purpose: To investigate the macular changes over time in eyes containing subretinal drusenoid deposits (also known as pseudodrusen) with no drusen >63 µm.

Methods: A consecutive series of patients were examined with color fundus photography, optical coherence tomography, and autofluorescence imaging with fluorescein angiography used as necessary.

Reticular pseudodrusen: current understanding.

Clin Exp Optom 2018 Oct 8. Epub 2018 Oct 8.

Centre for Eye Research Australia, Melbourne, Victoria, Australia.

Reticular pseudodrusen (RPD), also known as subretinal drusenoid deposits, represent a morphological change to the retina distinct from other subtypes of drusen by being located above the level of the retinal pigment epithelium. Although they can infrequently appear in individuals with no other apparent pathology, their highest rates of occurrence are in association with age-related macular degeneration (AMD), for which they hold clinical significance by being highly correlated with end-stage disease sub-types, choroidal neovascularisation and geographic atrophy. Reticular pseudodrusen are also found in other diseases, most notably Sorsby's fundus dystrophy, pseudoxanthoma elasticum and acquired vitelliform lesions. Read More

Swept source optical coherence tomography and optical coherence tomography angiography in pediatric enhanced S-cone syndrome: a case report.

J Med Case Rep 2018 Oct 3;12(1):287. Epub 2018 Oct 3.

Institute of Ophthalmology, Università Cattolica del Sacro Cuore - Fondazione Policlinico Universitario A. Gemelli-IRCCS, Rome, Italy.

Background: Enhanced S-cone syndrome is an autosomal recessive retinal dystrophy related to a defect in a nuclear receptor gene (NR2E3) that leads to alteration in cells development from rod to S-cone. This retinal dystrophy may be associated with retinal schisis. The aim of this report is to describe structural optical coherence tomography and optical coherence tomography angiography features in a case of enhanced S-cone syndrome associated with macular schisis.

Novel in-frame deletion in MFSD8 gene revealed by trio whole exome sequencing in an Iranian affected with neuronal ceroid lipofuscinosis type 7: a case report.

J Med Case Rep 2018 Sep 25;12(1):281. Epub 2018 Sep 25.

Department of Medical Genetics, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran.

Background: The neuronal ceroid lipofuscinoses are a group of neurodegenerative, lysosomal storage disorders. They are inherited as an autosomal recessive pattern with the exception of adult neuronal ceroid lipofuscinosis, which can be inherited in either an autosomal recessive or an autosomal dominant manner. The neuronal ceroid lipofuscinoses are characterized by accumulation of autofluorescent lipopigments in the cells and one of the most important pathological manifestations is ceroid accumulation in the lysosomes.

The small GTPase RAB28 is required for phagocytosis of cone outer segments by the murine retinal pigmented epithelium.

J Biol Chem 2018 Nov 18;293(45):17546-17558. Epub 2018 Sep 18.

From the Department of Ophthalmology and Visual Sciences, University of Utah Health Science Center, Salt Lake City, Utah 84132,

RAB28, a member of the RAS oncogene family, is a ubiquitous, farnesylated, small GTPase of unknown function present in photoreceptors and the retinal pigmented epithelium (RPE). Nonsense mutations of the human gene cause recessive cone-rod dystrophy 18 (CRD18), characterized by macular hyperpigmentation, progressive loss of visual acuity, RPE atrophy, and severely attenuated cone and rod electroretinography (ERG) responses. In an attempt to elucidate the disease-causing mechanism, we generated mice by deleting exon 3 and truncating RAB28 after exon 2. Read More
