The role of retinal cryopexy in the management of experimental perforation of the eye during strabismus surgery.

In order to investigate the role of retinal cryopexy in the management of accidental perforation of the globe during strabismus surgery, the retinas of 30 rabbit eyes were perforated with a needle simulating the clinical incident. Ten of these eyes received no further treatment, ten eyes were treated with moderate transscleral cryopexy of the surrounding retina, and the remaining ten eyes were treated with excessively heavy cryocoagulation. The incidence of secondary retinal detachment was identical in the first two groups of rabbits, while it was markedly increased in those rabbits treated with excessively heavy transscleral cryopexy (P less than .01). Based on these findings and a review of the literature, recommendations are made for the management of accidental perforation of the globe during strabismus surgery.

Consequence of perforation during peribulbar anesthesia in an only eye.

A patient with a blind fellow eye had cataract surgery in the right eye; anesthesia comprised an intraocular injection of lidocaine and bupivacaine. Forty-eight hours after surgery, visual acuity in the right eye was light perception (LP). Three days later, fundus examination showed inferotemporal hemorrhage, retinal whitening consistent with needle tracking, and a diffusely pale optic disc in the operated eye. Computed tomography showed an intact optic nerve in both eyes and high-density vitreal lesions in the right eye. Laser photocoagulation was applied to the retinal break. We believe that a jet stream of anesthetic agent may have transiently increased intraocular volume enough to occlude the central retinal artery. Although the retina remained attached, visual acuity failed to improve beyond LP.

Endolaser photocoagulation in penetrating and perforating intraocular foreign bodies.

Ten consecutive eyes that had undergone a pars plana vitrectomy and argon endolaser photocoagulation for penetrating or perforating posterior segment foreign bodies were reviewed. All eyes had undergone a pars plana vitrectomy plus or minus lensectomy, removal of the intraocular foreign body in those eyes with a retained foreign body, endolaser photocoagulation of posterior chorioretinal tears, and peripheral buckle for peripheral retinal pathology. Postoperatively (minimum follow-up, 6 months), all eyes had an attached retina. Eighty percent of the eyes had a visual acuity of 20/40 or better. Advantages of endolaser photocoagulation of posterior breaks include: microscopically controlled sealing of posterior tears, less destructive than posterior cryotherapy, effective when severe choroidal swelling is present, and absence of dispersion of viable retinal pigment epithelial cells which has been documented with external cryotherapy.

[Perforating eye injuries caused by darts].

Four perforating eye injuries sustained by children playing with darts are analyzed. The injuries occurred within a period of 17 months. All the patients had minor injuries of the anterior segment and severe injuries in the posterior segment, such as vitreous hemorrhages and double perforations. Precautions should be taken to prevent such injuries: games involving darts are not suitable for children.

Penetrating pellet fragmentation. A complication of ocular shotgun injury.

In three patients who had double-perforating ocular shotgun injuries, a single lead shotgun pellet apparently fragmented after striking the eye, resulting in two separate intraocular impact sites. The importance of detecting double-perforating eye injury and becoming aware of this potential complication with ocular shotgun injuries is emphasized.

Severe visual loss caused by ocular perforation during chalazion removal.

PURPOSE: To report two cases of ocular perforation during chalazion removal procedures leading to severe vision loss. DESIGN: Observational case series. METHODS: Two patients presented with unilateral decreased vision after chalazion removal procedures. Complete ophthalmologic examinations were performed. RESULTS: Examination revealed a cherry red spot and perforation site in the first patient. In the second patient, there was an intraocular gas bubble and ischemic retina. CONCLUSIONS: Local anesthetic injections for procedures such as chalazia removal can result in ocular perforation. We postulate that the intraocular injections led to extremely high pressures, compromising the blood supply to the retina and optic nerve. Anesthetic injections for all procedures, even chalazia removal, should be done with great caution. It is imperative to avoid injection if ocular perforation is suspected, as the high pressure may cause the majority of the visual morbidity.

Vitrectomy for accidental intraocular steroid injection.

BACKGROUND: Accidental perforation of the globe and intraocular injection of steroid is a potential complication of periocular injections. Final outcomes in eyes in which this complication has occurred have been reported to be unsatisfactory in the past. However, the advent of vitrectomy has altered their prognosis significantly. METHODS: A retrospective analysis was done of five cases of accidental intraocular steroid injection, treated by vitrectomy. Additional procedures involved treatment of retinal breaks (where required) with endolaser or transscleral cryopexy. Scleral buckling was done in one case. RESULTS: Barring one case in which retinal detachment developed, there were no postoperative complications. At last follow up all patients had satisfactory recovery of visual acuity; had attached retina; and quiet anterior chamber and vitreous cavities. CONCLUSION: Vitrectomy is associated with satisfactory results in cases of accidental intraocular steroid injection. Delay up to a few days does not seem to materially influence the outcome.

The perforation problem in hydatid disease.

Hydatidosis (echinococcosis) is endemic in the Mediterranean region, including Turkey. We evaluated the problem of perforation in hydatidosis. The clinical data on 21 patients with intra-abdominal hydatid cyst perforation who were treated in the last 10 years were evaluated retrospectively. Twelve patients (57%) were men and nine (43%) were women. Their average age was 40 (range = 20-65). Blunt trauma was the etiologic mechanism in four cases (19%). Except for a case with a cyst in the left inguinal region, most (95%) of the patients had primary hepatic hydatidosis (95%). The procedures used on the 30 cysts found in 21 patients were as follows: partial cystectomy and drainage in 21 (70%), total cystectomy in 5 (17%), partial cystectomy plus omentopexy in 2 (7%), and drainage plus vacuum obliteration in 2 (7%). The average postoperative hospital stay was 12 days (range = 6-30). Two patients (10%) had complications: an incisional hernia developed in one patient, and a gastrocutaneous fistula developed in the other. Albendazole (10 mg/kg/day) was prescribed for two months. The mean follow-up time was 80 months (range = 6-131). Three patients (14%) underwent additional surgery for recurrence at various times. The morbidity and mortality associated with perforated hydatid cysts were higher when compared with that of nonperforated cysts. Hydatidosis is endemic in Turkey and traffic accidents are common. When these factors coexist, hydatid perforation should be considered in trauma patients with stable hemodynamics, but suspicious abdominal findings. The choice of the operative approach should be based on the experience of the surgeon and regional characteristics.

An in-vitro study of irradiated vitreo-retinal membranes.

Standard perforating injuries were created in the right eye of 30 rabbits. Twenty of these had the site of injury irradiated using the radioactive ophthalmic 60Cobalt applicator. Vitreo-retinal membranes obtained from non-irradiated and irradiated eyes were propagated in vitro. The morphology and viability of the cells that grew as a monolayer was studied using phase, light and electron microscopy. The proportions of the different cell types that constituted the monolayer was determined using immunofluorescent staining techniques. Non-irradiated membranes elaborated an abundant outgrowth of healthy cells that were predominantly fibroblasts. Irradiated membranes developed a sparse outgrowth of cells with vacuolated cytoplasm and pyknotic nuclei indicating cell destruction. The majority of the surviving cells were glial, with fibroblasts and retinal pigment epithelial cells forming the remainder.

Treatment of posterior eye segment complications after perforating trauma.

168 perforating trauma cases that underwent vitreoretinal surgery in our hospital over a two year period were reviewed. A uniform surgical concept was applied in those severely injured eyes. Showing posterior eye segment complications that required vitreoretinal surgery and having at least light perception were the only two criteria to be eligible for this study. The anatomic and functional results in different trauma groups are discussed as well as indications and duration of silicone oil tamponade.
