The aim of this presentation is to illustrate the value of flourescein fundus photography in understanding and management of the following essentially vascular conditions of the eye:
2. Retinal vein thrombosis, mixed branch occlusion.
3. Retinal artery occlusion and anterior ischaemic optic neuropathy.
Papilloedema though usually associated with raised iniracranial tension can occur due to many other causes. In fact we have seen a large number of cases with gross papilloedema without raised intracranial tension. It can occur in hypotony, and in rise of pressure in central vein which impedes flow of blood from capillaries of nerve head, the circle of Zinn and Haller and so oedema results. It is also suggested that ischaemic leaky vessels on nerve head can cause oedema.
Central vein thrombosis
Clinically central vein thrombosis can be divided into two types:
1. Venous stasis retinopathy characterised b y haemmorrhages good visual acuity, good recovery, younger age.
2. Haemorrhagic retinopathy with lot of haemorrhages, marked visual loss, poor recovery, older age and associated arterial involvement.
The treatment regime, recommended by us is as follows:-Treatment of systemic condition, plasma expanders, plasmaphoresis, anticoagulannts stop contraceptive pills, treatment of glaucoma, steroids-(if E.S.R. high) photocoagulation.
Central artery occlusion
The main causes are emboli, carotid stenosis, atheroma of ophthalmic artery, diabetes, Burger disease, vasculitis.
The anterior ischaemic optic neuropathy is caused by occlusion of posterior ciliary arteries. Fluorescein angiography studies have shown that in cases of central artery occlusion there was also obstruction of posterior ciliary arteries as well.
Treatment-Treatment of systemic cause, CO 2 inhalation, anticoagulants, steroids (in arteries) and treatment of raised I.O.P.
The clinical note on 10 clinical cases were presented with illustrative projection slides of fluorescein photographs.
