                (c)             intraocular foreign body.
            Note 3: Examples of surgery or a therapeutic procedure include:
                (a)             cataract surgery;
                (b)            filler injection to the forehead, or the glabellar, nasal or nasolabial fold regions;
                (c)             intraocular or retrobulbar anaesthesia;
                (d)            intravitreal bevacizumab injection; and

            Note: specified list of drugs is defined in the Schedule 1 - Dictionary.
(38)      taking a combined oral contraceptive pill for a continuous period of at least 21 days within the one year before the clinical worsening of retinal vascular occlusion;
(39)      for retinal venous occlusion only:
(a)          having open-angle glaucoma, angle-closure glaucoma or ocular hypertension, at the time of the clinical worsening of retinal vascular occlusion;
             Note: ocular hypertension is defined in the Schedule 1 - Dictionary.
(b)          having chronic renal failure at the time of the clinical worsening of retinal vascular occlusion; or
             Note: chronic renal failure is defined in the Schedule 1 - Dictionary.
(c)          being severely dehydrated at the time of the clinical worsening of retinal vascular occlusion;
             Note: being severely dehydrated is defined in the Schedule 1 - Dictionary.
