Secondary Glaucoma Flashcards
What are the types of Secondary glaucoma
- Uveitis
- Lens luxations
- Intumescent cataract
- Phakolytic/phacoclastic uveitis
- Hyphema
- Intraocular neoplasia
- Aphakic
- Malignant/ciliary block
- Melanocytic/pigment cell proliferation
- Pigment cell exfoliation/anterior uveal cysts
- Giant retinal tears (Schwartz–Matsuno syndrome)
- Anterior chamber silicone oil
- Postoperative ocular hypertension
What Glaucoma is the Cairn Terrier predisposed to?
Ocular melanosis
What are the types of Primary glaucoma?
- Open/normal-angle/cleft: Acute/chronic
- Narrow/closed-angle/cleft: Acute/chronic
- Narrow/closed-angle cleft and pectinate ligament abnormalities: Acute/chronic
What are the congenital glaucomas?
- Pectinate ligament dysplasia
2. Goniodysgenesis
What can be viewed using gonioscopy?
The anterior opening of the ciliary cleft, pectinate ligaments and part of the uveal trabeculae
How can you view the whole of the ciliary cleft?
Ultrasound 20 MHz or higher
Describe the pathway of AH?
- Formation by the nonpigmented ciliary body epitheliae 2. Transport through the posterior chamber, pupil and into the anterior chamber
- Exit from the eye through the conventional (trabecular mesh- work) and unconventional (uveoscleral) pathways.
How can you view the ciliary cleft?
Gonioscopy
High-resolution ultrasonography (HRUS)
Ultrasound biomicroscopy (UBM)
Optical coherence tomography (OCT)
What does goniodysgenesis mean and what is a better term?
The failure to form discrete pectinate ligaments. The status of the deeper trabecular meshwork and extracellular matrix is unknown.
PLD is a better term
Define pectinate dyspasia?
Pectinate ligament dysplasia (PLD) is the consolidation of adjacent pectinate ligaments into broad sheets (initially termed mesodermal dysgenesis) with flow holes is often described in PACG
