A 28‐year‐old man, after subtotal resection of a Grade l‐ll frontal lobe astrocytoma, received 5600 cGy of radiotherapy in 200 cGy fractions to residual intracranial tumour. One year later he presented with severe bilateral retinopathy which, in appearance was consistent with retinopathy from irradiation. Total irradiation received by the retina of each eye (< 50 to 1500 cGy) was far less than the dose which commonly produces radiation retinopathy. Also, the pattern of retinopathy did not reflect the distribution of radiation received by the eye. Alternative causes for the retinopathy were sought but not found. Proliferative retinopathy occurred in each eye and one eye developed a dense vitreous haemorrhage. Argon laser pan‐retinal photocoagulation controlled the neovascularisation in the other eye. This patient has developed severe retinal ischaemia after a low dose of retinal irradiation.

Severe epistaxis after combined nasolacrmal duct probing and cardiac catheterisation in a one‐year‐old child is reported. The epistaxis followed streptokinase infusion given as treatment for femoral artery thrombosis secondary to cardiac catheterisation and necessitated nasal packing and blood transfusion. The authors recommend that probing not be undertaken in conjunction with another procedure if anticoagulant and/or thrombolytic agents are likely to be required.

Ophthalmic lasers are used as diagnostic as well as therapeutic modalities in patients with retinal diseases. Recent advances in laser technology have allowed more convenient selection of wavelength and a wide variety of delivery systems is available to deliver the laser energy to the retina. In addition, newer lasers that disrupt and cut tissue will become available for use in patients with retinal diseases. The use of imaging lasers and lasers in combination with dyes selectively to enhance their effects have become useful in diagnosis and understanding of pathophysiology of diseases. These lasers will also be therapeutically useful. This manuscript delineates the new types of diagnostic and therapeutic lasers, new imaging dyes and techniques as they apply to retinal diseases as well as the principles of laser‐tissue interaction as applied to the retina. This should allow the ophthalmologist who treats patients with retinal diseases to make more intelligent decisions regarding the use and acquisition of laser systems.

A presumptive clinical diagnosis of cytomegalovirus (CMV) retinitis was made in two patients presenting with atypical ophthalmologic findings. The diagnosis was confirmed by finding specific CMV DNA sequences in sampled vitreous fluid using a polymerase chain reaction (PCR) based assay. Neither of these patients yielded CMV on culture or PCR of peripheral blood leucocytes, nor was CMV present in tears or urine of either patient. Serum antibody titres were stable and did not help in establishing the diagnosis. This report suggests that CMV retinitis can occur in the absence of disseminated CMV disease.

An endonasal approach was used to restore lacrimal drainage in both primary and secondary obstructions. Patients in the primary group had a history of keloid scar formation, or wished to avoid a scar and declined to have surgery performed via an external approach. Patients in the secondary group had undergone one or more previous unsuccessful lacrimal drainage repairs. A fibreoptic endonasal telescope, linked to a video monitor, and appropriate nasal and lacrimal instruments, were used. The approach proved highly successful, in both anatomical and functional terms, in each group. In the secondary group, the endonasal approach allowed direct visualisation and repair of both nasal and lacrimal causes of failure; this approach is our preference in this group. In the primary group, endonasal instrumentation had no advantage over a conventional external operation, other than avoiding a scar. The application of laser technology may make the endonasal approach a realistic option in primary DCRs as well.
