Apologies about my delay in answering back-am on a business road trip with our laser company and whilst the wilds of Queensland and northern NSW a visual joy to be in, the internet connection can be 20thC. I had wondered because dogs have a vascular ring, cats don&#39;t so less cataract risk but also dogs get diurnal iop so higher in morning and wondered if this was a risk factor and hence why the dog woke up and within an hour had suddenly the lipid laden eye.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/239441?ContentTypeID=1Thu, 06 Oct 2022 07:43:02 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:2e75814f-53bb-4f8e-9d77-17a719311750Robert Lowe<p>Hi</p> <p>I&rsquo;m not sure there is much of a difference. Plenty of schnauzers out there with higher circulating lipids but only some have lipaemic aqueous.&nbsp;<br /><br /></p> <p>There is some evidence to suggest that hyperlipidaemia can induce low level vascular inflammation so it can be a cause of uveitis as well as secondary to uveitis. I suspect that nearly all lipid aqueous is as a result of another cause of low grade uveitis or extremely high but transitory hyperlipidaemia. That fact that they usually respond to topical corticosteroid even though the hyperlipidaemia persists indicates that the uveitis is what leads to the lipid aqueous rather than a difference in uveal barrier between the species</p> <p></p><div style="clear:both;"></div>
