Figure 1. Case referred for normal-tension glaucoma. 1A: Optic nerve head showing slight blurring at the nasal margin (green arrow) and temporal peripapillary atrophy (black arrow). 1B: Corresponding visual field showing an inferior defect. 1C and 1D: Reverse of the glaucomatous sequence of OCT profile curves (in black) showing a minimal rim width (1C) within the normal green band, while the nasal section of the retinal nerve fiber layer (RNFL) is located within the abnormal red band (1D). The RNFL also exhibits a wavy appearance related to its alteration. Radial OCT slices revealed optic nerve drusen buried in the superior and nasal portion of the optic nerve head delineated by the dotted white arrows. Figure 1: Courtesy of Nana Wandji Brenda.

OCT: A practical tool for diagnosing buried optic disc drusen

Dr Adèle Ehongo addresses the diagnosis of buried optic disc drusen (BODD) using Optical Coherence Tomography (OCT) and the importance of correlating visual field abnormalities and OCT data, especially in normal tension glaucoma, to distinguish it from Optic Disc Drusen (ODD).

Peripapillary intrachoroidal cavitation and myopic peripapillary changes

Peripapillary intrachoroidal cavitation and myopic peripapillary changes: Optical Coherence Tomography analysis.
Figure 1. Peripapillary intrachoroidal cavitation (PICC) with a full-thickness defect within the myopic conus. (A). Fundus image showing a circumscribed yellow-orange lesion (black star) at the outer and inferior border of the myopic conus, corresponding to a peripapillary intrachoroidal cavitation. A full-thickness defect (red star) is located within the myopic conus. (B) Section along the green arrow of the infrared image, through the full-thickness defect (red star). The remnant of nerve fibers (yellow arrow) herniate into the PICC cavity. ONH = optic nerve head. Note: Reprinted from Peripapillary Intrachoroidal Cavitation. Adèle Ehongo et al. ‘J. Clin.

Peripapillary Intrachoroidal Cavitation, a masquerade of normal-tension glaucoma

Dr Adèle Ehongo discusses peripapillary intrachoroidal cavitation (PICC), a masquerade of normal-tension glaucoma.
Figure 1. Landmarks of the peripapillary intrachoroidal cavitation (PICC). LC = lamina cribrosa. BM = Bruch’s membrane (dashed red arrow). SF = scleral flange, the sclera between the dura and the pia mater. D = dura mater. PICC (red star) is in front of the subarachnoid space (yellow star). It is a suprachoroidal detachment. It is suggested to be promoted by a direct traction force (blue arrow) of the dura mater during eye movements. A tangential component of this traction force squeezes the choroid at the end of the posterior outpouching (red arrowheads). The device used is the Spectral Domain OCT Spectralis® HRA-OCT, model S3300 (Heidelberg Engineering GmbH, Heidelberg Germany). Note: Reprinted from Peripapillary Intrachoroidal Cavitation.

Understanding the link between PICC and myopic complications

Dr Adèle Ehongo discusses the pathogenesis of peripapillary intra-choroidal cavitation and its implications for myopic complications.

Glaucoma clinic within the ophthalmology department

Professor Adèle Ehongo discusses her work in context of the ophthalmology department at Brussels University Hospital.
Figure 1. photo of a peripapillary intrachoroidal cavitation. The crescent-shaped atrophic area (red star), at the border of the optic nerve head (black star), called myopic conus, is alone in (A). It presents a circumscribed, yellow-orange lesion (white star) at its outer border in (B), corresponding to the peripapillary intrachoroidal cavitation. Note: Figures 1 and 2 are reprinted from Peripapillary Intrachoroidal Cavitation. Adèle Ehongo et al. ‘J. Clin. Med. 2023, 12, 4712’ Originally published by and used with permission from MDPI.
