This report describes the SERCAA multiplatform, multisensor, multispectral cloud product analysis algorithms. These algorithms incorporate high-resolution sensor data from multiple military and...
Autofluorescence of the crystalline lens in early and late onset diabetes.
Sparrow, J M, Bron, A J, Brown, N A, Neil, H A
Blue/green autofluorescence (excitation around 420 to 430 nm, emission around 520 nm) of the crystalline lens has been studied by an in vivo photographic method in two populations of diabetics and...
Biometry of the crystalline lens in late onset diabetes: the importance of diabetic type.
Sparrow, J M, Bron, A J, Phelps Brown, N A, Neil, H A
Lenticular and anterior chamber biometry were studied in non-cataractous eyes by means of Scheimpflug photography and digital image analysis. The study population consisted of 91 late onset diabetic...
An estimate of the size and shape of the human lens fibre in vivo.
Brown, N A, Bron, A J, Sparrow, J M
The size and shape of the lens fibres were estimated by specular reflex photography. The fibres were measured in three separate regions. Peripheral fibres have a mean width of 10.2 micron, the...
Control of astigmatism in cataract surgery.
A study is reported on cataract surgery, with intraocular lens implant, with measurement of the preoperative astigmatism and of the postoperative astigmatism over 28 weeks. Nine interrupted 10/0...
Central compaction in the process of lens growth as indicated by lamellar cataract.
Brown, N A, Sparrow, J M, Bron, A J
The lens growth through life is the net result of surface accretion partially offset by central compaction. Compaction has previously been shown to affect the cortex. The present study examines...
Dynamic nature of posterior subcapsular cataract.
Brown, N P, Bron, A J, Sparrow, J M
Posterior subcapsular cataracts were studied in 10 patients (19 eyes) and were photographed at four to 12 weeks intervals by the Oxford Retroillumination Camera. Changes in the fine structure of PSC...
The lens after renal transplantation.
Shun-Shin, G. A., Ratcliffe, P., Bron, A. J., Brown, N. P., Sparrow, J. M.
A single masked observer examined 55 non-diabetic patients chosen randomly from a population of patients who had undergone renal transplant. The mean age was 41 years and mean time from transplant...
Biometry of the crystalline lens in early-onset diabetes.
Sparrow, J M, Bron, A J, Brown, N A, Neil, H A
Lenticular biometry on non-cataractous lenses has been studied by means of Scheimpflug photography and digital image analysis in 153 patients with early-onset insulin-dependent diabetes and 153...
Cullinane, A B, Waldock, A, Diamond, J P, Sparrow, J M
Aim: To evaluate the correlation between internal slope analysis of the optic nerve head and visual field changes in normal eyes and those with ocular hypertension (OHT) and early glaucoma (POAG).
Effect of a patient training video on visual field test reliability
Sherafat, H, Spry, P G D, Waldock, A, Sparrow, J M, Diamond, J P
Aims: To evaluate the effect of a visual field test educational video on the reliability of the first automated visual field test of new patients.
Williams, C, Northstone, K, Harrad, R A, Sparrow, J M, Harvey, I
Background/aims: Preschool screening for amblyopia has controversially been abandoned in some localities within the United Kingdom, on the basis that there is no clear evidence of benefit to support...
Spry, P G D, Hussin, H M, Sparrow, J M
Aims: To evaluate performance of frequency doubling technology (FDT) perimetry using the Humphrey Matrix 24-2 thresholding program in a hospital eye service (HES) glaucoma clinic.
The sight test fee: effect on ophthalmology referrals and rate of glaucoma detection.
Laidlaw, D. A., Bloom, P. A., Hughes, A. O., Sparrow, J. M., Marmion, V. J.
OBJECTIVE--To assess changes, if any, in the numbers of referrals and outcome of glaucoma referrals to the hospital eye service since the introduction of the sight test fee on 1 April 1989....
