(15)      having an ocular or orbital infection involving the affected eye within the 30 days before the clinical onset of retinal vascular occlusion;
            Note 1: Examples of an ocular or orbital infection include:
                (a) cat scratch disease;
                (b) herpes zoster ophthalmicus;

(18)      taking a drug from the specified list of drugs within the 72 hours before the clinical onset of retinal vascular occlusion;
            Note: specified list of drugs is defined in the Schedule 1 - Dictionary.
(19)      taking a combined oral contraceptive pill for a continuous period of at least 21 days within the one year before the clinical onset of retinal vascular occlusion;
(20)      experiencing an acute hypotensive episode within the 24 hours before the clinical onset of retinal vascular occlusion;
            Note: acute hypotensive episode is defined in the Schedule 1 - Dictionary.
(21)      for retinal venous occlusion only:
(a)          having open-angle glaucoma, angle-closure glaucoma or ocular hypertension, at the time of the clinical onset of retinal vascular occlusion;
