Article Synopsis
  • Inherited retinal diseases (IRDs) are diverse eye disorders leading to vision loss due to retinal degeneration, with retinitis pigmentosa (RP) being the most common type.
  • A study involving 1210 IRD families in Japan identified 67 causal genes in 37% of these cases, primarily focusing on genetic mutations in EYS and RP1 genes.
  • The research highlighted a frequent missense variant in the EYS gene and identified two known mutations linked to autosomal recessive RP, along with a notable RP1 variant linked to autosomal recessive macular dystrophy/cone-rod dystrophy.

Purpose: Macular degeneration is the leading cause of blindness worldwide. In this study, we aimed to define a new subtype of macular-retinal dystrophy and its genetic predisposition in 5 families.

Methods: Exome sequencing was performed to determine the putative disease-causing genes in patients with inherited macular disorders confirmed through comprehensive ophthalmic examinations.

Purpose: To compare the efficacy and safety of a combination therapy of prednisolone and cyclosporine and corticosteroid pulse therapy in Vogt-Koyanagi-Harada (VKH) disease.

Study Design: A prospective, multicenter, randomized, non-inferiority trial.

Methods: Patients of new-onset acute VKH disease at 11 centers in Japan between 2014 and 2018 were randomized to a combination (oral prednisolone 60 mg daily with gradual taper-off to 35 mg/day and cyclosporine 3 mg/kg/day) and corticosteroid (methylprednisolone 1000 mg for 3 days followed by oral prednisolone) groups, and were followed for 1 year.

Purpose: Progressive addition lenses (PAL) are effective, particularly for middle-aged and elderly people who require reading spectacles. However, with PALs, peripheral vision may be distorted and blurred because of both the lateral bending of the surface and the effect of unequal bending of the light coming from an off-axis location in the tangential and sagittal directions, which may lead to a decrease in the quality of vision. Till date, no evaluation of PALs has been reported with regard to peripheral and binocular vision.
