Time domain vs. spectral domain in the measurement of the optic nerve head

The authors describe a prospective study of 40 participants (20 healthy and 20 with glaucoma) enrolled to compare the measurements of the optic nerve head (ONH) parameters given by time domain (TD) and spectral domain (SD) optical coherence tomography (OCT)....

Molecular genetics of achromatopsia

Achromatopsia is a rare autosomal recessive disorder of the cone photoreceptors. Typical characteristics of affected patients include the inability to distinguish colours, impaired visual acuity, photophobia and nystagmus. The condition is said to be more frequent in the Pingelapese population...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

Radiation maculopathy

This is a retrospective non-randomised study of 13 consecutive eyes of 13 patients affected by radiation maculopathy secondary to eye irradiation for primary uveal melanoma (Iodine-125 brachytherapy). All patients were treated with a single intravitreal 0.7mg dexamethasone implant and full...

CMV assessment

This is a retrospective, cross-sectional review of medical records from a consecutive series of patients with AIDS-related cytomegalovirus (CMV) retinitis who were examined at five HIV disease clinics in Yangon, Myanmar, in November 2006. All patients with CD4+ T lymphocytes...

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...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

Screening for amblyopia

The purpose was to determine the validity of the OPTEC 5500 vision screener in detecting visual acuity and amblyopia in paediatric patients aged 3-17 years with comparison to the Lea and Snellen tests. This was a cross-section study of 64...

Control of bleeding with diabetic vitrectomy under air

The authors describe a modified diabetic vitrectomy using continuous air infusion in diabetic eyes with severe fibrovascular proliferation. In their case series of 25 eyes (20 patients), intravitreal bevacizumab (1.25mg) was used one week prior to surgery. Fifteen eyes had...

IOP in children with uveitis

This is a retrospective study of paediatric uveitis (<16-years-old) between July 2002 to June 2016 of a total of 320 children from a single centre: 17.2 % (55/320 patients) developed raised IOP requiring therapy; 11.5% of eyes required glaucoma surgery...

Persistent anterior uveitis after cataract surgery

This retrospective cohort study was completed to help identify potential risk factors for developing persistent anterior uveitis (PAU) following uncomplicated cataract surgery in patients with no prior history of uveitis or autoimmune disease. A total of 3013 eyes (2019 patients)...

Radiotherapy for orbital apex cavernous haemangiomas

This is a review of six patients with cavernous venous malformations (haemangiomas) involving the orbital apex who were treated with fractionated stereotactic radiotherapy. Patients were diagnosed on MRI imaging with only one having had previous surgery to debulk the lesion....
