Imaging Studies VII: Vascular Imaging

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Summary

Morning glory disc anomaly (MGDA) can lead to vision loss and retinal issues. This case study explores potential causes of retinoschisis in MGDA, suggesting inner retina traction and cerebrospinal fluid pressure fluctuations are key factors.

Background:

Morning glory disc anomaly (MGDA) is a rare congenital condition affecting the optic nerve head.
MGDA is associated with vision impairment and an increased risk of developing maculopathy or retinal detachment later in life.
The underlying mechanisms of MGDA-associated maculopathy remain poorly understood.

Observation:

A case of a 31-year-old Black woman presenting with progressive vision reduction in the right eye due to MGDA-associated maculopathy.
Detailed morphological analysis of the optic disc and macula was performed using multicolour imaging and optical coherence tomography.
The patient's presentation highlights MGDA-associated maculopathy in an underrepresented demographic and age group.

Findings:

The study identified specific morphological characteristics of the optic disc and macula in the observed case.
Speculation on the role of centripetal inner retina traction in fluid accumulation within the inner retina.
Hypothesis regarding the influence of cerebrospinal fluid pressure fluctuations on the development of retinoschisis in MGDA.

Implications:

The findings suggest novel potential mechanisms contributing to retinoschisis in Morning glory disc anomaly.
Highlights the need for further research into the cause-and-effect relationship between MGDA and retinoschisis.
Contributes to a broader understanding of MGDA-associated maculopathy beyond typical demographics.
