“…The rapid recovery was also demonstrated via serial OCT tests, a useful quantitative tool for the determination and follow-up of papilledema throughout its whole clinical course. 1,13 Through the illustration of our extremely rare case and the related literature review, we have clearly shown OSAS as an independent etiological factor in IIH, which should be considered, particularly in patients with malignant IIH. An interesting point in our patient was the prominent finding of papilledema, which did not have an overwhelming response to shunt surgery (even in the immediate postoperative period).…”

The association between idiopathic intracranial hypertension (IIH) and obstructive sleep apnea syndrome (OSAS) constitutes an interesting point of discussion regarding clinical approaches as well as the underlying pathophysiological mechanisms. Here, the case of a 42-year-old female with malignant IIH and OSAS is illustrated. Initially, the patient was treated with lumboperitoneal shunt surgery. However, OSAS surgery provided total recovery from the recurrent symptoms developing secondary to lumboperitoneal shunt malfunction. The authors point out the importance of identifying OSAS as a crucial causative agent in some IIH subtypes. Future studies are warranted to clarify this underestimated association.

“…The correlation between OCT and Frisen grading for papilledema has been demonstrated in several studies [62][63][64]. One study found a positive correlation between Frisen grading and RNFL thickness with r = 0.7952 [63]. Taking it one step further, Vartin et al looked at both RNFL thickness and peripapillary total retinal thickness (TRT) and concluded that TRT is a more sensitive indicator for mild papilledema [62].…”

The detection of elevated intracranial pressure (ICP) is of paramount importance in the diagnosis and management of a number of neurologic pathologies. The current gold standard is the use of intraventricular or intraparenchymal catheters; however, this is invasive, expensive, and requires anesthesia. On the other hand, diagnosing intracranial hypertension based on clinical symptoms such as headaches, vomiting, and visual changes lacks sensitivity. As such, there exists a need for a noninvasive yet accurate and reliable method for detecting elevated ICP. In this review, we aim to cover both structural modalities such as computed tomography (CT), magnetic resonance imaging (MRI), ocular ultrasound, fundoscopy, and optical coherence tomography (OCT) as well as functional modalities such as transcranial Doppler ultrasound (TCD), visual evoked potentials (VEPs), and near-infrared spectroscopy (NIRS).

Evaluation des modifications structurelles de la tête du nerf optique et de la rétine péri-papillaire par tomographie en cohérence optique dans l'hypertension intracrânienne idiopathique Introduction. Une détection fiable de l'oedème papillaire est une considération essentielle pour établir le diagnostic de l'hypertension intracrânienne idiopathique (HTIC), mais l'examen ophtalmoscopique du fond d'oeil de la tête du nerf optique (ONH) est une mesure subjective limitée par l'expérience de l'examinateur, le degré de la collaboration et l'optique de l'ophtalmoscope, le rendant souvent peu fiable pour détecter un oedème précoce et pour évaluer les améliorations ou aggravations initiales. Le but de l'étude était d'évaluer le rôle de la tomographie par cohérence optique (OCT) dans le diagnostic et la surveillance de l'oedème papillaire produit par IIH.
