Sympathetic ophthalmia remains a dreadful complication of ocular traumas, accidentally but also surgically occurred; it may induced by certain ocular components, which are strongly antigenic, such as the uveal material or the recently discovered retinal material, represented by the interphotoreceptor binding protein and the S-antigen. The occurrence of the disease seems to be favoured by the transferring of the antigenic material through the conjunctival lymphatic mesh opened by the trauma. The paper presents a female patient with sympathetic ophthalmia occurred after cataract surgery.

The incidence of endophthalmitis following pediatric anterior segment surgery is currently unknown. The paucity of reports of this entity has led some observers to recommend simultaneous bilateral surgery for congenital cataracts or glaucoma. In this study, we surveyed over 500 pediatric ophthalmologists and glaucoma specialists concerning their knowledge of, or involvement with, endophthalmitis following pediatric intraocular surgery. Seventeen cases of endophthalmitis were documented to occur out of 24,000 reported surgical cases. This results in an incidence estimate of 0.071%, or 7 cases per 10,000, which is similar to that recently reported following adult extracapsular cataract extraction. The presence of infection was diagnosed by the 3rd postoperative day in 82% of cases. An organism was documented by culture in 65% of cases. The organism was gram positive in all cases. Visual outcome was generally poor with 65% having no light perception. The presence of possible concurrent risk factors for postoperative endophthalmitis, including nasolacrimal duct obstruction and upper respiratory infection, was noted in 8 of the 17 cases.

Bacterial attachment to intraocular lenses (IOLs) can be a cause of infectious endophthalmitis following cataract surgery. In this study, Pseudomonas aeruginosa and Staphylococcus aureus adhered in vitro to untreated poly(methyl methacrylate) (PMMA) and to surface passivated PMMA lenses. The IOLs were placed in bacterial suspensions (1 x 10(7) cfu/ml) in vitro. Significantly fewer S. aureus attached (P < .05) to the normal PMMA IOLs (4,535 +/- [SD] 3,052 bacteria/mm2) and to passivated PMMA IOLs (8,720 +/- 10,040 bacteria/mm2) than did P. aeruginosa (normal PMMA: 67,808 +/- 45,070 bacteria/mm2, passivated PMMA: 85,795 +/- 70,647 bacteria/mm2). The differences in bacterial attachment to surface passivated IOLs and to untreated PMMA lenses were not significant.

A retrospective study was conducted of 308 eyes with pathologic myopia obtained from 202 patients (23 surgical eyes; 285 post mortem eyes) over a 67-year period. Histopathologic findings and percentage of eyes affected, in decreasing order of frequency, were myopic configuration of the optic nerve head, 37.7%; posterior staphyloma, 35.4%; degenerative changes of the vitreous, 35.1%; cobblestone degeneration, 14.3%; myopic degeneration of the retina, 11.4%; retinal detachment, 11.4%; retinal pits, holes, or tears, 8.1%; subretinal neovascularization, 5.2%; lattice degeneration, 4.9%; Fuchs spot, 3.2%; and lacquer cracks, 0.6%. The reasons for enucleation in the surgically obtained eyes included, in decreasing order of frequency: degeneration after retinal detachment; secondary glaucoma; endophthalmitis; postsurgical epithelial ingrowth; expulsive hemorrhage; degeneration after cataract extraction; and presumed intraocular tumor. Clinicopathologic correlations are discussed.

We reviewed the medical records of four patients with marked intraocular inflammation and hypopyon as the initial manifestation of retained lens fragments after phacoemulsification. The severe inflammatory reaction occurred between one month and one year after the cataract extraction. All four patients underwent pars plana vitrectomy to remove the lens fragments. The vitreous specimens were cultured to rule out infectious endophthalmitis. In all patients, no organisms were isolated from the vitrectomy specimens placed on both aerobic and anaerobic media. All patients had improved vision and resolution of the marked intraocular inflammation after vitrectomy. Echography was useful in establishing the diagnosis in these uncommon cases.

Ten consecutive cases of perforating ocular injuries with retained intraocular foreign bodies over a period of 2 years were reviewed retrospectively in this study. All cases were operated upon by a 3 port pars plana vitrectomy and if necessary endolaser done. All ten cases (100%) were successful in terms of intraocular foreign body removal through the pars plana sclerotomy but ultimately we lost three [3] [30%] cases of which two had retinal detachments with P.V.R. D-3 preoperatively and the other had endophthalmitis. Of the seven (70%) successful cases four eyes (40%) had a post-operative vision of 6/12 or better while 2 [20%] had 6/24 and the last had 6/60 [10%]. Nine cases [90%] had a magnetic Intraocular foreign body. Various complications of Intraocular foreign bodies like vitreous haemorrhage, retinal incarceration, cataract and retinal detachment were noted preoperatively. Silicone oil was used in three (30%) cases. Sulfur Hexafluoride was used in 5 cases (50%). Endolaser photocoagulation was done in 7 cases (70%).

A case of Enterococcal endophthalmitis developed following an extracapsular cataract extraction. The infection was successfully treated with intravenous and intravitreal ampicillin, but a secondary glaucoma led to a later enucleation. We report a case of postoperative endophthalmitis with an unusual etiology, which did not respond to common treatment.

Persistent intraocular inflammation after cataract surgery with intraocular lens implantation is acquiring importance. Frequently, chronic uveitis or the "toxic lens syndrome" have to be differentiated from bacterial infection. This report describes five cases with chronic postoperative endophthalmitis where the anaerobic bacterium Propionibacterium acnes was found to be the causative organism. Adequate anaerobic culture media and proper sampling from the area around the lens haptics are the most important requirements for the detection of P. acnes.

A case of successful treatment by vitrectomy and lensectomy of early-stage endogenous endophthalmitis caused by Enterococcus faecalis was reported. The case was a 50-year-old man with poorly controlled diabetes. Following T-tube drainage for a necrotic cholecystitis operation, he developed iridocyclitis in both eyes as well as fever. At the time of his first visit to our clinic, his right eye had already lost light perception. His left eye had visual acuity recognizing hand movement, marked uveitis, complicated cataract, and dense vitreous opacity. As gram-positive cocci were isolated from the aspirated vitreous, lensectomy and vitrectomy under irrigation with antibiotics were conducted. After the administration of systemic postoperative antibiotics and human immunoglobulin, the patient showed remarkable improvement in the state of his ocular fundus. By 60 days after the surgery, the visual acuity of his left eye recovered to 0.2. Endogenous Enterococcus faecalis endophthalmitis has rarely been reported in Japan. The diagnosis and treatment of this disease with reference to the above findings were discussed.

Cataract extraction with posterior chamber intraocular lens implantation is rarely complicated by an acute, sterile, anterior segment inflammation. We report three unrelated cases of acute intraocular inflammation following uncomplicated cataract extraction and posterior chamber intraocular lens placement. A constellation of clinical features were found in these cases. The hallmark of this entity was an acute toxic inflammatory reaction occurring in the anterior segment on the first postoperative day. Typically, widespread corneal edema with diffuse corneal endothelial damage occurred, accompanied by a fixed, dilated pupil with significant iris atrophy and sometimes a severe secondary glaucoma. Since all cultures were negative, the resulting inflammatory processes were not a result of endophthalmitis. We believe that a toxic insult introduced into the anterior chamber at the time of surgery precipitated the acute inflammatory processes seen in these cases.
