Blood and vascular disorders may present as intraocular hemorrhage, retinal detachment, secondary glaucoma, and papilledema. Other endectocides, such as milbemycin oxime and ivermectin, which are not registered for treatment of sarcoptic mange in dogs, have been reported to be effective depending on the dosage and route of administration. Accompanying pododermatitis is common. These mites are closely related to the Sarcoptic mange mite, which causes mange in dogs. The rabbits are extremely pruritic, and the parasites are difficult to eliminate on domestic rabbits. Atypical, including localized, clinical forms that are probably linked to extensive use of insecticides or acaricides are being increasingly seen. Feline herpesvirus 1 is also associated with ulcerative and stromal keratitis, proliferative keratoconjunctivitis, corneal sequestrum, corneal symblepharon, and keratoconjunctivitis sicca.
