What is the complications of glaucoma surgery?
Main body. Common retinal complications after glaucoma surgeries include choroidal detachment; ocular decompression retinopathy; haemorrhagic choroidal detachment; hypotony maculopathy; malignant glaucoma; vitreous haemorrhage; bleb endophthalmitis; retinal detachment.
How do you detect scleral spur in UBM?
The scleral spur in UBM images is identified based on the differential tissue density between the collagen fibers of the scleral spur and the longitudinal muscle of the ciliary body.
What is the function of Biomicroscopes?

What is UBM Ophthalmology?
Ultrasound Biomicroscopy (UBM) is a technique primarily used for imaging of the anterior segment (AS) of the eye. It was first introduced in the early 1990’s by Foster and Pavlin as a way to obtain cross-sections of the eye at microscopic resolution.
How is UBM done?
During a UBM exam, the patient receives anaesthetic eye drops to numb the eyes. The UBM probe is filled with sterile, distilled water and placed upon the eye. This probe emits high-frequency sound waves that are reflected through the eye to create an image of the eye’s interior.
What is the best surgery for glaucoma?
The most common go-to surgical option for many doctors when it comes to glaucoma is laser surgery. Laser surgery is a treatment that you can choose to have at a clinic or your doctor’s office. Its advantage is that it is a procedure that does not require overnight admission afterward.
What is the success rate of glaucoma surgery?
The surgical success rates were 97.1%, 76.5%, and 44.0% at 3 months (90 days), 6 months (180 days), and 12 months (365 days), respectively….Patient demographics.

How can you tell if you have a scleral spur on OCT?
Scleral spur location was assessed in AS-OCT images by 2 examiners with glaucoma subspecialty training and was defined as the point where there was an inward protrusion of the sclera with a change in curvature of its inner surface. Results Scleral spur location could be determined in 72% of the images of the right eye.
Where is the scleral spur located?
The scleral spur is a fibrous ring that, on meridional section, appears as a wedge projecting from the inner aspect of the anterior sclera (Figs 3-1 and 3-2). The spur is attached anteriorly to the trabecular meshwork and posteriorly to the sclera and the longitudinal portion of the ciliary muscle.
What is B-scan in ophthalmology?
B-scan ultrasonography (USG) is a simple, noninvasive tool for diagnosing lesions of the posterior segment of the eyeball. Common conditions such as cataract, vitreous degeneration, retinal detachment, ocular trauma, choroidal melanoma, and retinoblastoma can be accurately evaluated with this modality.
What does a Pachymeter do?
A pachymeter is a medical device used to measure the thickness of the eye’s cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, Cataract, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.
What is the new surgery for glaucoma?
MIGS, or minimally invasive glaucoma surgery, is a relatively new approach to glaucoma treatment. Referring to a group of minimally invasive procedures, MIGS offers alternative surgical treatment options for glaucoma that pose fewer risks than traditional glaucoma surgeries.
What is a scleral spur?
The scleral spur is a shelf-like structure formed from a projection of the sclera, bordered anteriorly by the corneoscleral portion of the TM and posteriorly by the longitudinal fibers of the ciliary muscle.
