Postoperative outcome of trans pars pklana vitrectomy in the treatment of posterior and intermediate uveitis

We performed standard pars plana vitrectomies in 17 eyes with uveitis which were complicated with vitreous opacities. Postoperatively, visual acuity was improved in 11 eyes(64.7%),maintained in4 eyes(23.5%) and decreased in 2 eyes (11.8%). Four weeks after vitrectomy, inflammatory cells were rarely noticed in the anterior vitreous of all eyes. We suggest that early surgical approach is of value for visual improvement in the management of uvitis eyes with vitreous opacity.

The Clinical Evaluation of Pars Plana Vitrectomy in various Ocular Disease

We reviewed the hospital records of 104 consecutive eyes in 101 patients who underwent pars plana vitrectomy at Presbyterian Medical Center from January 1993 to December 1995 and studied the postoperative visual acuity and postoperative complications. Possible indications for pars plana vitrectomy were follows: complications of proliferative diabetic retinopathy (30.7%),complications of other types of proliferative retinopathy except proliferative diabetic retinopathy(25.0%),complications of anterior segment surgeries (14.4%), complex retinal detachments(8.7%), intraocular inflammations and uveitis (8.7%), macular diseases (6.7%), and complications of ocular trauma (5.8%), Regarding postoperative final visual acuity, 53 eyes(51.0%) were improved, 30eyes(28.8%) were stabilized, 21eyes(20.2%) were worsened. Intraoperative or postopertive cataract, retinal breaks or retinal detachment were most frequent complications. We expected that pars plana vitrectomy might be indicated in various ocular diseases containing proliferative diabetic retinopathy.

A Case of the Orbital Aspergillosis

Aspergillus is also a saprophytic, ubiquitous fungus that is normally not pathogenic in humans. When it does appear as a source of infection, the rhinoorbital route of entry seemes to parallel that of the Phacomycetes. We experienced a case of orbital aspergillosis in healthy woman. There was no intracraneal extension. In spite of local infiltration of amphotericin B solution through maxillary sinus and aggressive systemic amphotericin B therapy, ocular symptom and sign was not improved. So we performed orbital exenteration and adjunctive amphotericin B and itraconazol systemically. Six months later the patient is alive without recurrence. We reviewed the available literatures regarding this uncommon disease.
