We present a patient with chronic myeloid leukaemia (CML) who had marked bilateral disc swelling as part of his initial presentation. This occurred in the setting of raised intracranial pressure (ICP), with normal cerebrospinal fluid (CSF) composition and cell content, and normal neuroimaging. We discuss the possible mechanisms which could lead to disc swelling in CML and conclude that the raised ICP and subsequent papilledema in our patient were the result of poor absorption of CSF into the dural venous sinuses. We propose that the very high white cell count (WCC) led to a hyperviscosity state which resulted in poor absorption of CSF and in so doing, created a clinical picture of benign intracranial hypertension (BIH).

The technique of endocapsular cataract extraction and intraocular lens implantation surgery provides optimal surgical conditions and more reliable intraocular lens positioning in the capsular bag. Several capsulectomy techniques are in use to remove anterior capsule from the central zone. The Koch endocapsular punch provides a new technique for creating a continuous anterior capsulectomy.In this study the Koch punch was used in 96 eyes consecutively undergoing intended endocapsular cataract extraction and intraocular lens implantation. Ninety‐five eyes had appropriate lens centration at six months. There were no cases of vitreous loss. Ninety‐nine per cent of cases had visual acuity of 6/6 or better at six months.This data demonstrates the Koch endocapsular punch to be an effective and safe means for anterior capsulectomy.

We describe a case of topical exposure to a commercial solution of paraquat. Chronic, severe ocular surface destruction resulted, probably due to absorption of the herbicide into the surface tissues, facilitated by a surfactant present in the preparation, and to intracellular redox cycling of the paraquat cation. Ocular paraquat toxicity is described and explained in the context of the toxicity of systemic absorption.

NADPH‐diaphorase histochemistry was used to identify and analyse the topography of cones in adult human retinae (in the age range 44 to 68 years). Retinae were treated for NADPH‐diaphorase reactivity, present in vascular walls, amacrine cells and cone and rod outer segments; a subpopulation of less intensely reactive profiles, morphologically resembling cones, possibly represents the blue cone population. Regularly spaced pairs of cones (one intensely labelled and one weakly labelled cone) were also apparent throughout the retina, and were most common along the horizontal meridian, particularly towards the periphery.The diameters and distributions of labelled cone outer segments were assessed using image analysis. Cone density in the adult retina ranged from 2000 per mm2 in the temporal periphery, to 82 000 to 120 000 per mm2 at the fovea centralis. Distribution patterns confirmed the presence of a cone streak, extending from the foveal region into nasal retina, but no evidence of superio‐inferior asymmetry was detected.
