  SIGNIFICANCE Nonarteritic ischemic optic neuropathy (NAION) has been linked with vascular insufficiency, although the pathophysiology remains elusive. Optical coherence tomography angiography (OCTA) is a promising technology that noninvasively evaluates optic disc perfusion and that may help to characterize peripapillary vascular changes in NAION. PURPOSE This study aimed to evaluate peripapillary vascularity in NAION eyes and to compare it with fellow unaffected eyes and healthy control eyes using OCTA. METHODS In this cross-sectional study, OCTA of the optic nerve head was obtained in 10 nonacute unilateral NAION and 12 healthy age-matched controls using ZEISS Angioplex. Quantitative analysis of peripapillary retinal and ...

  Purpose: To evaluate the superficial retinal vascular plexus density using optical coherence tomography angiography (OCTA) in cases of strabismic amblyopia. Methods: Ten eyes of 10 patients with purely strabismic amblyopia underwent detailed ocular evaluation followed by the assessment of the superficial retinal plexus vascular density using OCTA (Topcon DRI OCT Triton, Swept Source OCT, Topcon, Japan). Ten contralateral normal eyes of the same patients were considered as control. All these 20 eyes underwent a 4.5 × 4.5 mm cube scan OCTA centered at the fovea. Using the Topcon propriety software all 20 eyes were assessed for the capillary plexus ...

3. Intraoperative optical coherence tomography-guided scleral suture passage while performing surgery on extraocular muscles

  Sir, Microscope-integrated intraoperative optical coherence tomography (iOCT, 2 mm depth penetration) helps in achieving the optimal results by providing the real-time images of tissue manipulation during the surgery. The iOCT is of great value while performing lamellar corneal surgeries, cataract surgeries, and intraocular lens implantation surgery. [1] , [2] It has also been noted to provide an advantage during placement of the glaucoma drainage devices in cadaveric eyes and needling of the blebs. [3] , [4] Pasricha et al . described the four-dimensional visualizations of the muscle and the scleral wound while passing the scleral sutures. [5] A 45-year-old male patient with alternate ...

4. Retinal nerve fiber layer and ganglion cell layer changes on optical coherence tomography in early multiple sclerosis and optic neuritis cases
  
  Explore Indian Journal of Ophthalmology (IJO) Dec 28 2017 Ophthalmology
  
  Purpose: To study the retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) changes on optical coherence tomography in early multiple sclerosis (MS) patients. Methods: A prospective cohort study was conducted at a tertiary care center. Patients of early MS (expanded disability status scale <3) with or without optic neuritis (ON) and idiopathic ON were included. Twenty age-matched individuals were taken as controls. Changes in RNFL and GCL thickness were evaluated along with the correlation with visual function parameters such as visual acuity, contrast sensitivity, and visual evoked response at first visit and again at six months. Results: Forty-four ...
