Metamorphopsia in idiopathic epiretinal membranes
The Amsler grid is commonly used for self-monitoring, but is qualitative and has low sensitivity. The M-chart reduces the amount of spatial redundancy (‘filling in’) in the Amsler grid. The Orientation Discrimination (OD) test studied in this paper consists of...Silmo Academy by the IOA hailed a great success

Two bifocals and a trifocal
The authors compare the optical outcomes of two bifocal intraocular lenses (AcrySof ReSTOR +2.50 Diopter [D] add +3.0D add) with a trifocal lens (AT LISA tri 839MP). The optical qualities of the lenses were quantified by measuring the modulation transfer...
Biometry measure after cycloplegia
The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...
Visual fields and OCT in hydroxychloroquine retinopathy
It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...Demyelinating optic neuropathy
Introduction Optic neuritis (ON) is an inflammatory process affecting the optic nerve. After glaucoma, it is the most common optic neuropathy affecting patients under the age of 50. The usual presentation of typical ON is unilateral subacute loss of vision...
OCT-A imaging in Grave’s orbitopathy and orbital decompression
In this case series of 12 patients and 24 orbits, the authors describe the changes in the optic nerve and peripapillary blood vessel density in patients with moderate to severe Grave’s Orbitopathy (GO) undergoing orbital decompression. The patients undergoing orbital...Ocular manifestations of multiple sclerosis: an overview
Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS), in which there is dissemination of lesions in time (two or more clinical events) and space (multiple lesions seen on brain and spinal imaging). The pathophysiology...New SEE Summit speaker announced
ABDO has announced that Andrew Clark, BSc (Hons), MSc, AIEMA, will be speaking at the SEE Summit 2023.
OCT in peripheral corneal thinning
This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...
