Muscle insertion measurement by ultrasound biomicroscopy

The aim of this study was to evaluate the accuracy of ultrasound biomicroscopy (UBM) preoperatively and postoperatively in patients having primary horizontal muscle surgery. Sixteen eyes of 15 patients with concomitant horizontal strabismus were evaluated; mean age 21.1 ±3.3 years,...

Modified technique in place of ultrasound biomicroscopy

The authors describe a modified immersion B-scan ultrasonography that includes a standard B scan probe of 10MHz, a surgical glove and sterile saline to fill a finger of the surgical glove – tied off to create the desired immersion standoff...

Ultrasound biomicroscopy (part 2): primary angle closure

Patients with primary angle closure or primary angle closure glaucoma [PAC(G)] comprise a significant subgroup affecting around 10% of glaucoma patients amongst Caucasians. Assessment of the patient with angle closure, or narrow angles, requires gonioscopy. However, whilst identifying the presence...

The interpretation and use of ultrasound biomicroscopy (part 1)

Ultrasound Biomicroscopy (UBM) has become increasingly important for the diagnosis of a variety of anterior segment pathologies. Most ophthalmologists are familiar with conventional B-scan ultrasonography techniques, which operate at lower sound frequencies (7.5 to 20MHz). UBM is an ultrasound technique...

Smartphone ophthalmoscopy vs. slit-lamp biomicroscopy in diabetic retinopathy

In this prospective, comparative, clinical study the authors’ aim was to assess the reliability and accuracy of smartphone ophthalmoscopy as compared with standard slit-lamp biomicroscopy in the grading of diabetic retinopathy. One hundred and twenty consecutive, new, diabetic patients underwent...

The prevalence of macular cysts in patients with clinical cone-rod dystrophy determined by spectral domain optical coherence tomography

Cone-rod dystrophy is a progressive photoreceptor disorder which has multiple inheritance patterns. It is rare, with a prevalence of 1 in 40,000. Macular cysts are well recognised in other photoreceptor conditions such as retinitis pigments and choroideraemia, while they are...

Detecting muscle insertion position by ultrasound

The purpose of this study was to investigate the accuracy to locate muscle insertion positions before and after strabismus surgery using wide-field ultrasound biomicroscopy with the bag / balloon technique. Thirty-nine muscles of 22 adult patients aged 34.7 ±15.5 years...

A ciliary body tumour

The authors describe a case report of a 60-year-old woman found to have advanced angle closure glaucoma in her right eye and appositional closure of half of the left eye and no glaucoma. The patient had previously undergone two trabeculectomies...

Rotational stability of angle supported phakic IOL

The authors evaluate 50 eyes of 28 patients that underwent an angle fixated phakic intraocular lens (IOL) implantation (Acrysof Cachet). All eyes had moderate to high myopia (-5.25 to-19.63 dioptres) and IOL sizing was performed as per the manufacturer’s recommendation....

Lens surgery in patients with lens subluxation misdiagnosed as primary angle-closure glaucoma

Lens subluxation can be caused by many conditions including Marfan syndrome and other hereditary conditions, and blunt trauma. Lens displacement can cause pupillary block and angle closure. This is commonly misdiagnosed as primary angle closure glaucoma (PACG), which can lead...
