Antiacne Medications Pseudotumor Cerebri

Optic Disc Swelling

The exact incidence of optic disc swelling and idiopathic intracranial hypertension in patients using antiacne medication is not known so far. The investigators hypothesize that swelling of retinal nerve fibre layer measured by optical coherence tomography is more frequent then assumed so far.

aICP in Glaucoma and Papilledema

Open-angle GlaucomaPapilledema

Glaucoma remains a disease with an unclear and complex underlying pathophysiology. Recently, researchers have emphasized not only intraocular pressure (IOP) or vascular dysregulation, but also translaminar pressure's (TPG) role in glaucoma (TPG=IOP-ICP). A higher TPG may lead to abnormal function and optic nerve damage due to changes in axonal transportation, deformation of the lamina cribrosa, altered blood flow, or a combination thereof leading to glaucomatous damage. However only invasive ICP measurements are available within the contemporary medicine. The ideas for non-invasive ICP measurement have been approached since about 1980. Most of the proposed technologies were based on ultrasound and were capable of monitoring blood flow in intracranial or intraocular vessels, cranium diameter, or acoustic properties of the cranium. Broad research has extended into sonography of optic nerve sheath and its relation with elevated ICP. However, most of these correlation-based methods had the same problem-the need of individual patient specific calibration. Seeking to measure absolute ICP values, researchers from Kaunas University of Technology created a non-invasive method, which does not need a patient specific calibration. The method is based on direct comparison of ICP value with the value of pressure Pe that is externally applied to the tissues surrounding the eyeball. Intracranial segment of ophthalmic artery (OA) is used as a natural sensor of ICP and extracranial segment of OA is used as a sensor of Pe. The special two depth transcranial Doppler (TCD) device is used as a pressure balance indicator when ICP = Pe. The aim of our study is to assess TPG in patients with primary open open-angle glaucoma (POAG). In addition the investigators want to measure ICP in patients with papilledema (PE) in order to compare them with glaucoma patients.

Effectiveness of Multimodal Imaging for the Evaluation of Retinal Oedema And New vesseLs in Diabetic...

Proliferative Diabetic RetinopathyDiabetic Macular Edema

Given the high number of people with DMO and PDR, the need for patients to be seen at short follow-up intervals, the need for frequent treatments and the requirement for long-term follow-up, there is a very large workload in Hospital Eye Services related to DMO/PDR which is making it difficult for the NHS to cope with the demand, in particular, due to shortage of ophthalmologists. This is only expected to get worse given the increasing prevalence of DM. Identifying new ways of increasing the NHS capacity and efficiency without compromising the quality of care would greatly benefit the NHS. The purpose of this study is to determine whether successfully treated patients with DMO and PDR could be followed up without a face-to-face examination by an ophthalmologist. EMERALD will evaluate a new care pathway which will include multimodal retinal imaging and separate image assessment by trained ophthalmic graders. This new pathway will be compared to the current standard care pathway: for DMO: ophthalmologist evaluating patients in clinic by slit-lamp biomicroscopy and with access to OCT images; for PDR ophthalmologists evaluating patients in clinic by slit-lamp biomicroscopy. EMERALD will compare how accurate the new pathway is at determining which patients have active or inactive disease. The costs and acceptability of current and new models of care will also be compared.

Ocular Point of Care Ultrasound (POCUS) to Detect Optic Disc Swelling in Comparison to Ophthalmologic...

Papilledema Associated With Increased Intracranial Pressure

Pediatric emergency department (PED) physicians frequently encounter children with symptoms that warrant evaluation of the optic disc for suspected increased intracranial pressure (ICP) such as headache, blurred vision, recurrent vomiting etc. Fundoscopic examination, by the PED physician, is considered an essential modality for assessment of the optic disc and the diagnosis of papilledema. Obtaining good visualization of the optic disc requires patient compliance, the ability to open the eyelids, the absence of opacities in the ocular media and a sufficiently large pupillary aperture. Hence, different levels of PED physician training, lack of cooperation, significant ocular or periorbital trauma, contraindications to mydriasis and severe photophobia may hinder direct fundoscopic evaluation. In the investigators' PED, children requiring fundoscopy are sent to a formal ophthalmologic examination. The investigators aim to evaluate the yield of optic disc height as measured with ocular point of care ultrasound to detect optic disc swelling in comparison to ophthalmologic examination as the gold standard.
