Palpebral Fissure Response to Phenylephrine Indicates Autonomic Dysfunction in Patients With Type 1 Diabetes and Polyneuropathy.

Purpose: The superior and inferior tarsal muscles are sympathetically innervated smooth muscles. Long-term diabetes often leads to microvascular complications, such as, retinopathy and autonomic neuropathy. We hypothesized that diabetes induces (1) sympathetic paresis in the superior and inferior tarsal muscles and that this measure is associated with (2) the severity of diabetic retinopathy, (3) the duration of diabetes, and (4) autonomic function.

Liraglutide Treatment Does Not Induce Changes in the Peripapillary Retinal Nerve Fiber Layer Thickness in Patients with Diabetic Retinopathy.

Liraglutide treatment has shown promising anti-inflammatory and nerve regenerative results in preclinical and clinical trials. We sought to assess if liraglutide treatment would induce nerve regeneration through its anti-inflammatory and neurotrophic mechanisms by increasing peripapillary retinal nerve fiber layer (RNFL) thickness in individuals with long-term type 1 diabetes. Secondary analyses were performed on a prospective, double-blinded, randomized, placebo-controlled trial on adults with type 1 diabetes, distal symmetric polyneuropathy (DSPN), and confirmed diabetic retinopathy, who were randomized 1:1 to either 26 weeks placebo or liraglutide treatment.

Intravitreal bevacizumab treatment for exudative choroidal neovascularisation in best vitelliform macular dystrophy.

Purpose: To describe results of intravitreal bevacizumab treatment of the secondary choroidal neovascularisation in Best vitelliform macular dystrophy in an adult and paediatric patient, and present the management of three asymptomatic patients with confirmed BEST1 gene mutation.

Case Series Description: Five patients from the same family with the Best vitelliform macular dystrophy are presented. In two patients (aged 63 and 4 years) secondary choroidal neovascularisation caused a rapid decline in visual acuity.
