OCT angiography and retinal vein occlusions
In this retrospective, observational case series, the authors set out to evaluate the morphology of the superficial and deep capillary plexa of eyes that suffered a retinal vein occlusion (RVO) on OCT angiography (OCTA) and compare the findings with fluorescein...
Intraoperative floppy iris syndrome and prevalence of intraoperative complications
Alpha-blockers (particularly of the selective type) are known to be associated with intraoperative floppy iris (IFIS) and poor dilation, which can present in various severities during cataract surgery and need to be recognised in order to avoid intraoperative complications. Methods...
RAPD in glaucoma screening
A study was conducted to investigate the relative afferent pupillary defect (RAPD) by swinging flashlight as a potentially useful screening test for glaucomatous optic neuropathy. The authors recruited 107 subjects with or without glaucoma from a clinic population. A medical...
Pupil abnormalities after orbital surgery
This is a retrospective review of 287 patients who underwent removal of an orbital cavernous haemangioma (cavernous venous malformation), to ascertain the incidence of surgically induced pupillary abnormalities. Forty-four patients had lesions removed from the anterior or extraconal orbit, none...
Use of RAPDx device with optic nerve disease
The authors have previously reported on use of the RAPDx device for evaluating relative afferent pupillary defects (RAPD). RAPDx objectively determines the magnitude of RAPD by presenting light stimuli alternately to pairs of eyes with laterality. The parameters of amplitude...
Does religious fasting affect intraocular pressure or retinal parameters?
Nearly one billion Muslims fast every year during the month of Ramadan. Due to the difference between the lunar and solar calendars, religious fasting time can range from 11 to 17 hours per day. This prolonged abstinence from food and...Feb/Mar 2015 Quiz 1
A 79-year-old male presented to the ophthalmic emergency department with a three week history of left eye pain. He also reported visual deterioration in the left eye over the same period. He suffered from degenerative myopia, with his spectacle prescription...
Air or SF6 in DMEK
This retrospective study compared descemet’s membrane endothelial keratoplasty (DMEK) outcomes in 136 consecutive eyes of 68 patients. All patients underwent DMEK for Fuch’s endothelial dystrophy, where consecutive eyes received 100% air bubble during first eye surgery and 20% sulphur hexafluoride...
Delayed angle closure in pseudophakia and repeated intravitreal therapy
The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...
Use of the RAPDx device to evaluate efficacy of treatment in patients with optic nerve disease
The RAPDx objectively determines the RAPD magnitude by alternately presenting light stimuli to each eye and deriving amplitude and latency scores. The authors of this paper evaluated the amplitude and latency scores from the RAPDx together with other ophthalmic investigations...
A case report of alternating anisocoria with associated nasal congestion
The authors have described a group of healthy individuals who show alternating anisocoria, in a previous paper. In these cases, the pupil asymmetry alternates between eyes every few hours, with no observed instances when both pupils are equal in size....
