Rural endophthalmitis.

The antibiotic regimens recommended for empiric use in posttraumatic endophthalmitis are based on data collected from medical centers in large metropolitan areas. In rural areas, trauma resulting in endophthalmitis frequently involves injuries with perforating objects that are contaminated with organic matter. These rural cases therefore may not be comparable with endophthalmitis occurring after nonrural injuries. A 10-year retrospective analysis was performed to investigate the incidence of rural endophthalmitis as well as determine the type of causative organisms. Endophthalmitis developed in 24 (30%) of 80 patients with rural penetrating trauma, compared with 23 (11%) of 204 patients with nonrural penetrating trauma. Of 24 patients, Bacillus spp were isolated in 11 (46%), followed by gram-negative rods in 7, Staphylococcus epidermidis in 6, and streptococcal species in 5. In 10 (42%) of these 24 patients with rural trauma, more than one organism was isolated. Bacillus spp were involved in six (60%) of ten of these mixed infections. Based on these findings, the authors suggest an intravitreal regimen of gentamicin along with either vancomycin or clindamycin for the empiric therapy of rural endophthalmitis.

The treatment of serous macular detachment secondary to choroidal melanomas and nevi.

The authors successfully treated with laser photocoagulation five patients who had a serous macular detachment secondary to leakage from a pigmented choroidal tumor. Three patients had dye leakage on fluorescein angiography from a choroidal neovascular membrane. The subretinal fluid resolved in all three patients after the neovascular membrane was obliterated by either krypton red (2 patients) or argon green (1 patient) laser photocoagulation. The other two patients had prominent leakage from a localized choroidal neovascular membrane as well as mild diffuse leakage over the entire tumor. Focal argon laser treatment to the neovascular membrane alone did not cause permanent resolution of the subretinal fluid. The fluid did resolve, however, after the entire area of diffuse leakage was retreated with photocoagulation. In one of the patients who received both focal and confluent laser treatment, the choroidal tumor grew in a collar-button fashion through Bruch's membrane at the original site of focal treatment. This eye was enucleated, and results of histopathologic examination showed a choroidal melanoma.

Prognosis of foveal splitting rhegmatogenous retinal detachments.

Retrospectively reviewing 4,966 patients with rhegmatogenous retinal detachments, we identified 21 patients with foveal split detachments who had no coexisting macular disease and who had been followed at least 6 months postoperatively. All detached retinas were anatomically reattached with one operation. The average preoperative and postoperative visual acuity was 20/50. Because eyes with foveal split detachments have a good visual prognosis when the retinas are anatomically reattached, we recommend that they be treated urgently, as if they had a macular-spared detachment.

Microscope light-induced maculopathy in combined penetrating keratoplasty, extracapsular cataract extraction, and intraocular lens implantation.

A characteristic retinal phototoxicity reaction was noted in four patients who underwent penetrating keratoplasty, extracapsular cataract extraction (ECCE), and intraocular lens (IOL) implantation. This complication has been well documented in association with other ocular procedures, but only one previous similar case has been reported. The authors bring this potential complication to the attention of corneal surgeons, discuss the risk factors, and offer suggestions on prevention.

Results and complications of pneumatic retinopexy.

Fifty-one patients with primary rhegmatogenous retinal detachment (RD) were treated by pneumatic retinopexy. The overall success rate for reattachment with one operation was 63%. Of the 34 phakic eyes, 25 (74%) were reattached; of the 17 aphakic or pseudophakic eyes, seven (41%) were reattached (P less than 0.05). Postoperative complications included the development of new tears (22%), inadequate closure of the original tear, shifting and delayed absorption of subretinal fluid, and opening of previously closed tears. Pneumatic retinopexy is a valuable new technique; however, careful patient selection and postoperative management is required.

Occlusion of bridging or avulsed retinal vessels by repeated photocoagulation.

A technique is described for occlusion of bridging vessels associated with retinal breaks, and recurring vitreous hemorrhage. Argon laser photocoagulation, applied around and to the vessel in repeated sessions, produces scarring and progressive thinning of the retina until laser energy absorbed in the deep pigmented layers can reach the vessel and occlude it. Seventeen patients presenting with vitreous hemorrhage from bridging vessels were treated. Vitreous hemorrhage recurred in only two patients, one of whom had not returned for completion of treatment. The authors conclude that repeated argon laser photocoagulation is a safe, simple, and effective method for preventing recurrent vitreous hemorrhage from bridging vessels.

Cytomegalovirus infection in a healthy adult associated with recurrent branch retinal artery occlusion.

The authors report a 16-year-old healthy male who developed branch retinal artery occlusions sequentially in both eyes. A few vitreous cells and retinal vasculitis were associated findings. A complete work-up of the patient for an etiology for the occlusions failed to show any possible embolic source. Spinal fluid studies showed increased protein content and lymphocytic pleocytosis. Serologic studies showed a tenfold rise in the cytomegalovirus (CMV) titer. Other viral titers did not rise. CMV could not be cultured from the patient's body. The case represents a possible cause of the so-called idiopathic recurrent branch retinal artery occlusion syndrome.
