Background/purpose: To analyze the influence of a cilioretinal artery (CRA) on macular and peripapillary vessel density in healthy eyes as measured using optical coherence tomography angiography.
Methods: A total of 83 eyes of 83 patients were included in this study. Optical coherence tomography angiography was performed using the RTVue XR Avanti with AngioVue (Optovue Inc). The macula was imaged with a 3 × 3-mm scan, whereas for the optic nerve head a 4.5 × 4.5-mm scan was taken. Optical coherence tomography angiography images of the optic nerve head were screened for the presence of a CRA.
Results: In 31 eyes, a CRA was detected (37.3%). The vessel density in eyes with a CRA was significantly lower within the optic nerve head (P = 0.005) but higher in the peripapillary capillary network (P < 0.001) and (whole en face) macular superficial capillary plexus (P = 0.025), when compared with eyes with no CRA.
Conclusion: Our findings reveal that in eyes with a CRA, the vessel density in the peripapillary and macular superficial capillary plexus is increased, whereas the optic nerve head perfusion (as indicated by vessel density in the inside disk region) is decreased. This has to be considered when analyzing quantitative optical coherence tomography angiography parameters in scientific and clinical applications.
Introduction: Wolfram syndrome, a rare autosomal recessive disorder, is characterised by diabetes insipidus, juvenile diabetes mellitus, optic nerve atrophy and deafness (DIDMOAD).
Case Report: We present a case of a 21-year-old male diagnosed with Wolfram syndrome who underwent cochlear implantation due to progressive hearing loss. The patient first complained of bilateral hearing loss at the age of 8 years.

Purpose: To demonstrate the response of a juxtapapillary retinal hemangioblastoma (JRH) to belzutifan in a patient with Von-Hippel-Lindau syndrome (VHL).
Methods: This case report includes fundus photography and optical coherence tomography to compare a juxtapapillary retinal hemangioblastoma (JRH) before and 24 months after treatment with belzutifan.
Results: An 18-year-old woman with VHL was diagnosed with a juxtapapillary retinal hemangioblastoma (JRH) at age 13.
Background: The new optic neuritis (ON) classification leads to a change in how ON patients are grouped. Our aim is to appraise the clinical features and prognoses of patients with autoimmune ON not associated with MS.
Methods: Patients referred to our neuro-ophthalmology laboratory were enrolled to this retrospective study.
Purpose: To analyze patients with optic disc drusen (ODD), with emphasis on modern diagnostics.
Materials And Methods: Research of the literature was conducted, together with a retrospective statistical analysis of patients with ODD. The group included individuals with ODD diagnosed using at least one of the following (ultrasound - USG, optical coherence tomography - OCT, fundus autofluorescence - FAF).
