Pupillary Block Glaucoma Secondary to Phacodonesis in Pseudoexfoliation
Summary
Pseudoexfoliation (PXF) can cause unilateral narrow angle glaucoma due to lens instability. Early detection via gonioscopy and anterior chamber assessment is crucial for preventing angle closure glaucoma in PXF patients.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Anterior Segment Imaging
Background:
- Pseudoexfoliation (PXF) is a common condition associated with various ocular pathologies.
- Angle closure glaucoma is a serious condition that can lead to vision loss.
- The specific mechanism of angle closure in PXF is not well-characterized.
Purpose of the Study:
- To present a clinical case of unilateral narrow angle glaucoma in a patient with pseudoexfoliation (PXF).
- To review the literature on pseudoexfoliation-related angle closure.
- To characterize the mechanism of angle closure in this specific case.
Main Methods:
- Clinical case presentation.
- Slit lamp examination.
- Anterior segment ultrasound biomicroscopy (UBM).
- Literature review.
Main Results:
- A case of unilateral narrow angle glaucoma secondary to pseudoexfoliation (PXF) was documented.
- The mechanism involved pupillary block due to anterior lens subluxation caused by zonular weakness.
- UBM confirmed the anterior segment changes.
Conclusions:
- Pseudoexfoliation can lead to narrow angles and angle closure glaucoma through specific mechanisms.
- Periodic gonioscopy and anterior chamber depth evaluation are recommended for PXF patients.
- Prophylactic laser peripheral iridotomy may be considered to prevent angle closure glaucoma.

01:25Glaucoma: 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...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:27Open 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.

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
