Screening for hydroxychloroquine retinopathy

The American Academy of Ophthalmology has updated the recommendations for screening for hydroxychloroquine retinopathy based on new scientific evidence that toxicity is not rare when hydroxychloroquine is used long-term, and that risk is dependent on the daily dose by weight....

DALK as an early therapeutic option for Acanthamoeba keratitis

Eleven patients with Acanthamoeba keratitis (AK) were treated by early therapeutic deep anterior lamellar keratoplasty (DALK). All surgeries were performed in patients who had no response to standard medical therapy of chlorhexidine gluconate, propamidine isethionate and neomycin sulphate, within 10-15...

How to achieve 1% solution of Lissamine green

Lissamine green (LG) concentration of 1% is clinically effective in the diagnosis of ocular surface disease. LG is now commercially available only in a form of dye-impregnated strips, whose concentration is insufficient. This study examined how to achieve 1% concentration...

Diabetic polyneuropathy and risk of developing diabetic retinopathy

Diabetic polyneuropathy (DPN), diabetic retinopathy (DR) and diabetic nephropathy are widely classified as microvascular complications of diabetes. DPN, which may cause complete sensation loss, is another common complication of DM. The DPN-related diminished sensation presents a significant risk factor for...

Outcomes of Hughes flap in lower eyelid reconstruction

One hundred and 22 consecutive patients who underwent tarsoconjunctival advancement flap surgery for lower eyelid defects were part of this study. Ninety percent of them had lesion excision using Mohs micrographic surgery. Eighty percent of these were for basal cell...

Neuro-ophthalmological symptoms in patients with cerebral venous sinus thrombosis

The authors of this article have evaluated the neuro-ophthalmological symptoms of 49 patients with cerebral venous sinus thrombosis. They have evaluated the onset of the disease as well as the symptoms reported. The authors present extensive clinical information for individual...

Structural effects of migraine on the retina

Migraine is a common, chronic, multifactorial neuro-vascular disorder typically characterised by recurrent attacks of disabling headache and autonomic nervous system dysfunction (migraine without aura). Up to one third of patients also have neurological aura symptoms (migraine with aura). The objective...

Wide variation in the volume of the sphenoid trigone

This is a radiological study of the volume of the sphenoid trigone in normal subjects. The authors were interested to see how much volume could be gained by removal of the trigone during an orbital decompression for thyroid eye disease....

Is an increased homocysteine level associated with greater risk of AMD?

Basic research studies have implicated homocysteine in causing vascular endothelial dysfunction and inflammation, and this has been borne out in large observational studies which suggested that elevated homocysteine is associated with increased risk of cardiovascular disease. In order to determine...

OCT imaging of occluded puncta

This is a description of the use of enhanced depth optical coherence tomography (OCT) to see whether a patent ampulla or canaliculus is detectable in patients with absent or occluded puncta. Nine occluded puncta of six patients with epiphora were...

ABCA1 mediates lipid efflux in the retina

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...

Risk factors for NTG in a young Korean population

Previously known ocular and systemic risk factors for normal tension glaucoma (NTG) include myopia, peripapillary atrophy, disc haemorrhage, migraine, obstructive sleep apnoea, thyroid disease and cerebral infarction. However, most NTG risk factor studies have examined patients aged 40 years and...
