Clinical Findings

Vitreous opacities, so called floaters or mouches volantes may occur in normal eyes as well as in eyes of patients with vitreoretinal disorders. In rare cases vitreous floaters may also develop after cataract extraction 4 and scleral buckling surgery. Floaters are caused by condensed vitreous fibers or glial tissue of epipapillary origin that adhere to the posterior vitreous cortex 7 and result in entoptic phenomena. Myopic patients are 9 more likely to develop vitreous floaters 4 . Float ers...

Of a Chorioretinal Scar

Pars plana vitrectomy (PPV) is increasingly used for primary repair of pseudophakic retinal detachment 1-22 . The development of wide-angle viewing systems and improvements in vitrectomy instrumentation have contributed to expanding the role of PPV in the management of RRD. At the end of the surgical procedure the vitreous cavity is filled with a tamponade agent (air, gas or silicone oil) to allow sufficient time for chorioretinal adhesion to develop and avoid seepage of fluid through the...

Free Graft Translocation Surgery and Complication Profile

Translocation of a free graft of the RPE and choroid was successfully performed in all patients. Four patients presented with tight retina-RPE adhesion resulting in macular hole formation during hydrodissection in one instance. In one patient a small peripheral retinal tear or dialysis occurred intraoperatively and was treated by cryotherapy or by photocoagulation. Postoperative complications presented as PVR with retinal detachment in 5 eyes, subretinal hemorrhage in 1 eye, fibrinous reaction...

Air Versus Silicone Oil Exchange for PFCL

It has been noted that slippage does not occur so readily when a direct silicone oil PFCL exchange is used instead of first exchanging the PFCL for air and then injecting silicone oil 23 . When silicone oil is exchanged for PFCL, there are two endotamponades inside the vitreous cavity and four phases in contact with one another. The situation is very complicated, as with four phases there are multiple interfaces, namely silicone Fig. 4.5 Procedure of silicone oil PFCL exchange. a The edge of...

Treatment Approaches in Patients with Geographic Atrophy

While there is currently no pharmacological treatment available to reactivate RPE function, replacement strategies of the diseased RPE become more attractive. Attempts to replace diseased RPE by autologous IPE cells in suspension did not result in a long-term improvement in visual acuity 10, 11, 12 19 , although a small case series report stated that in non-exudative AMD, RPE suspension transplants showed no evidence of rejection and were associated with the disappearance of drusen 1 . Still,...

Info

Pars plana vitrectomy with a ntimycotics within 1 day possibly IOL explanation Pars plana vitrectomy with a ntimycotics within 1 day possibly IOL explanation all over the world have been divided into two camps those who avoided early vitrectomy and those who claimed the obligation of immediate complete pars plana vitrectomy. Even though recent peer-reviewed literature includes numerous publications on the treatment of postoperative endophthalmitis, none of the papers offers a prospective,...

Therapeutic Options

So far, the treatment of failed MH persistent or re-opening MH is still a challenge for the retinal surgeon. Many therapies have been suggested over time, but in the literature only non-randomized and noncontrolled studies have been reported, carried out in small anecdotal series. Therefore, at present there is no first-line management and many surgeons give up treatment after one or two attempts at surgery. Suggested management options have been 2 observation, laser photocoagulation on the...

And Postoperative Posturing

Intraocular tamponade following vitrectomy for macular holes is believed to facilitate re-apposition of the rim of a detached neurosensory retina and to provide an interface with the vitreous fluid component that serves as a template for glial migration across the macular hole. Consistently favorable anatomic and visual outcomes can be achieved by long-acting gas tamponade with strict face-down posturing as originally advocated 25 . In a comparative study of 52 eyes, use of 16 perfluoropropane...
