Background And Objective: Difficulty exists in the follow-up of proliferative macular telangiectasia type 2 (MacTel 2) cases after anti-vascular endothelial growth factor (VEGF) treatment due to staining in fluorescein angiography (FA) and alteration in retinal layers by optical coherence tomography (OCT). Herein, the authors report three cases in which OCT angiography (OCTA) could resolve this issue.
Patients And Methods: In this retrospective, observational case series, diagnosis of MacTel 2 was made based on clinical examination, FA, OCT, and OCTA at presentation. Regression of neovessels was monitored by OCT and OCTA.
Results: OCTA could delineate neovessels before treatment in all cases and facilitate differentiation between active and regressed lesions after treatment. Simultaneous OCT images were less easily appreciated due to altered retinal structure secondary to degenerative nature of the disease.
Conclusion: OCTA could be the tool of choice to monitor neovascular response to anti-VEGF treatment in proliferative MacTel 2. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:485-491.].

Analysis of macular retinal thickness in polyarteritis nodosa using spectral domain optical coherence tomography.
J Ophthalmic Inflamm Infect
January 2025
School of Medicine, National Taiwan University, Taipei, Taiwan.
Purpose: To identify the macular retinal layer thickness changes in polyarteritis nodosa (PAN) patients without pathological findings appearing in color fundus photography (CFP), and to investigate the correlations with disease durations.
Methods: A total of 24 PAN patients who had been for 3 years or more and underwent SD-OCT were recruited from the UK Biobank, with exclusions for diabetes, eye disease, or abnormal CFP findings. Only the right eyes were included, with each PAN patient paired one-to-one with a control matched for age, sex, and ethnicity.
New Directions for Ophthalmic OCT - Handhelds, Surgery, and Robotics.
Transl Vis Sci Technol
January 2025
Department of Biomedical Engineering, Duke University, Durham, NC, USA.
The introduction of optical coherence tomography (OCT) in the 1990s revolutionized diagnostic ophthalmic imaging. Initially, OCT's role was primarily in the adult ambulatory ophthalmic clinics. Subsequent advances in handheld form factors, integration into surgical microscopes, and robotic assistance have expanded OCT's utility and impact outside of its initial environment in the adult outpatient ophthalmic clinic.

NIHR Biomedical Research Centre, Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology, London, United Kingdom.
Purpose: To investigate the effect of average intraocular pressure (IOP) on the true rate of glaucoma progression (RoP) in the United Kingdom Glaucoma Treatment Study (UKGTS).
Methods: UKGTS participants were randomized to placebo or Latanoprost drops and monitored for up to two years with visual field tests (VF, 24-2 SITA standard), IOP measurements, and optic nerve imaging. We included eyes with at least three structural or functional assessments (VF with <15% false-positive errors).

January 2025
Department of Ophthalmology, Massachusetts Eye and Ear, Harvard Medical School, Boston, MA.
Purpose: To report on optical coherence tomography angiography (OCTA) in patients with a type 1 Boston keratoprosthesis (KPro) and determine its feasibility through assessment of imaging artifacts.
Methods: KPro and non-KPro subjects were matched for age, gender, and glaucoma diagnosis. OCTA images of the peripapillary optic nerve were obtained, reviewed by 2 readers masked to the diagnosis for artifacts and usability, and used for microvascular measurements.
