5. Increasing Airflow. Dogs with floppy ears, especially if they are heavy, are more likely to develop ear infections, as the ear canals are dark and are not exposed to the air.
A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments. [citation needed] Scleral buckles come in many shapes and sizes.
The risk of retinal detachment is the greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event.. The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears/detachment.
Retinal detachments are divided into three main types based on their distinct causes. [6] Rhegmatogenous retinal detachment is caused by a tear or break in the retina. [6] [9] This allows vitreous humor, the fluid that normally sits in the center of the eye, to build up behind the retina.
The retinal degeneration appears to be related to apoptosis of these cells. [11] SARDS must be distinguished from other causes of sudden blindness that have no visible pathology, including retrobulbar optic neuritis , a tumor at the optic chiasm , or other central nervous system diseases.
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [ 1 ] it is characterized by the bilateral degeneration of the retina , causing progressive vision loss culminating in blindness.
During rhegmatogenous retinal detachment, fluid from the vitreous humor enters a retinal hole. The mechanisms by which retinal holes or tears form are not fully understood yet. The accumulation of fluid in the subretinal space and the tractional force of the vitreous on the retina result in rhegmatogenous retinal detachment.
