Figure 9-1: Posterior vitreous detachment as seen with the +8 lens of the ophthalmoscope. |
|
Figure 9-2: Vitreous hemorrhage limited to posterior vitreous region in aphakic eye. (Reproduced, with permission, from Coleman DJ: Ultrasound in vitreous surgery. Trans Am Acad Ophthalmol Otolaryngol 1972;76:469.) |
|
Figure 9-3: Total retinal detachment viewed horizontally below iris plane. A vitreous membrane connecting two leaves of retina is clearly demonstrated. (Reproduced, with permission, from Coleman DJ: Ultrasound in vitreous surgery. Trans Am Acad Ophthalmol Otolaryngol 1972;76:469.) |
|
Figure 9-4: Vitreous membrane extending along posterior limiting membrane of vitreous from ora to ora. Retina is in place. (Reproduced, with permission, from Coleman DJ: Ultrasound in vitreous surgery. Trans Am Acad Ophthalmol Otolaryngol 1972;76:469.) |
|
Figure 9-5: Vitreous membrane connecting two leaves of detached retina. Lens is normal. (Reproduced, with permission, from Coleman DJ: Ultrasound in vitreous surgery. Trans Am Acad Ophthalmol Otolaryngol 1972;76:469.) |
|
Figure 9-6: Schematic representation of vitreous collapse causing the retina to tear and detach. |
|
Figure 9-7: Large intravitreal cavity filled with liquid breakdown products of syneresis. |
|
Figure 9-8: Posterior vitreous detachment. |
|
Figure 9-9: Liquid vitreous tends to be drawn into intravitreal cavity on abrupt eye motion (left) and expelled at rest (right). |
|
Figure 9-10: Local vitreoretinal adhesion. |
|
Figure 9-11: Left: Retinal tear. Right: Retinal detachment. |
|
Figure 9-12: Left: Ophthalmoscopic view of retinal tear. Right: Ophthalmoscopic view of retinal detachment. |
|
Figure 9-13: Acute vitreous hemorrhage. A retinal vessel ruptures due to vitreous traction. |
|
Figure 9-14: Chronic vitreous hemorrhage. |
|
Figure 9-15: Abrupt rotation of globe generates eddy currents in liquid vitreous, a result of inertial lag (left), that tends to lift the retinal flap and surrounding sensory retina (right). |
|
Figure 9-16: Enlargement of retinal detachment due to inertial lag of liquid vitreous within the retina. |
|
Figure 9-17: Traction detachment of retina. |
|
Figure 9-18: Proliferative vitreoretinopathy. Left: Contracture of membrane adherent to outer retinal surface. Right: Contracture of inner retinal membrane. |
|
Figure 9-19: Vitreous surgery. Top left: Position of corneal contact lens and intraocular devices. Top right: Removal of preretinal membrane. Bottom: Placement of sutures at completion of procedure. |
|
Figure 9-20: Scope of vitreous surgery. Top: Removal of vitreous hemorrhage. Residual hemorrhage will clear in time from vitreous remnants. Middle: Reattachment of traction retinal detachment following vitrectomy. Bottom: Vitreous contracture complicating retinal detachment. Removal of vitreous and repair of retinal detachment. |
