Spontaneous expulsive suprachoroidal hemorrhage.

PURPOSE: To present a 90-year-old patient with spontaneous expulsive suprachoroidal hemorrhage (SESCH). This unique case suggests a mechanism of SESCH, which is still under debate. METHODS: The patient, who had corneal inflammatory disease and diabetes mellitus, atherosclerosis, and glaucoma, presented with active ocular bleeding and expulsion of intraocular tissues. Almost the entire cornea was absent, except for several small and irregular areas in its periphery. Histopathologic evaluation of the eviscerated contents was performed. RESULTS: Clinicopathologic evaluation revealed acute inflammation of the corneal remains as well as intraocular inflammation. Inflammatory necrosis of choroidal vessels was evident. CONCLUSION: The findings point to the assumption that choroidal bleeding, secondary to vascular inflammatory necrosis, was the initial event in this case of spontaneous expulsive suprachoroidal hemorrhage. Presumedly, the intraocular pressure level was very high owing to continuous bleeding, which could result in a very large, rather than localized, tearing of the peripherally inflamed cornea.

Halting pterygium recurrence by postoperative 5-fluorouracil.

PURPOSE: To investigate the efficacy of postoperative 5-fluorouracil (5-FU) in halting recurrence of pterygium. METHODS: Early recurrence of pterygium was detected in six eyes of six patients aged 40 to 66 years that, over a 3-year period, had undergone pterygium excision in our institution, using the "bare sclera" technique. Each of the hyperemic fibrovascular tissues was found to override the cornea by 1.5 mm or less in length. Five of these eyes had undergone a primary excision and one, a second operation (with intraoperative mitomycin C). Upon diagnosis, each eye was treated with two to four injections of 5-FU, administered into the dome of the fibrovascular tissue. The dose of 5-FU per injection was 1 to 3 mg (mean, 2.1 +/- 0.8 mg). Of all 126 eyes that underwent pterygium surgery during that 3-year period, pterygium recurred in nine additional eyes but was found to be 2 mm or more in length in each. These eyes were not treated by 5-FU. RESULTS: In five of the six treated eyes, the pterygium became clinically atrophic and the recurrence process was stopped. No renewal of the recurrence process was detected after 12 months or more of follow-up. No major complications were related to the use of 5-FU. CONCLUSION: This pilot study suggests that when early recurrence of pterygium is already evident, 5-FU treatment into the dome of the fibrovascular tissue may be beneficial in halting its progression, by rendering it atrophic. A prospective, randomized, controlled study is required to confirm the efficacy of this approach.

Mini-trabeculectomy in eyes with high risk of scarring: midterm follow-up.

PURPOSE: To report on the surgical outcome after at least 1 year of follow-up of mini-trabeculectomy (without scleral radial incisions), which took place in eyes at high risk of postoperative filtering bleb scarring. METHODS: In a prospective, institutional study, mini-trabeculectomy was performed on 26 eyes of 26 consecutive patients aged 40 years and older who had undergone a previous intraocular surgery or had had a post-traumatic recessed anterior chamber angle. The surgical procedure, a modification of the standard trabeculectomy, involved a 3-mm fornix-based conjunctival flap, sclerostomy at 1 mm from the limbus, and a sclerocorneal tunnel without radial incisions. During surgery, 0.4 mg per ml of mitomycin C was applied in the scleral pocket of each eye for 3 minutes. Of the 26 eyes, each of two eyes underwent an intraocular intervention during the first postoperative year and therefore was evaluated only for surgical complications. Another eye underwent inferior mini-trabeculectomy, and three other eyes did not complete 12 months of follow-up. Twenty eyes have completed 12 months or more of follow-up and were included in the midterm calculations of intraocular pressure control. RESULTS: Mean preoperative intraocular pressure (n = 20) was 32.2 +/- 9.5 mm Hg with 3.3 +/- 0.9 hypotensive medications. After 12 to 37 months (mean, 22.1 +/- 6.6) of follow-up, intraocular pressure was 20 mm Hg or less in 18 of 20 eyes (90%) and the mean intraocular pressure was 17.4 +/- 2.9 mm Hg (range, 12 to 23) with 1.1 +/- 1.2 hypotensive medications (range, 0 to 4). At that time, the filtering bleb was low and fleshy in appearance in 15 eyes (75%). Postoperative complications of the 22 eyes included early postoperative aqueous leakage in one eye (4.5%); cataract extraction took place in one eye and vitrectomy was performed in another eye, 7 and 3 months postoperatively, respectively. The four eyes that were excluded from the study had controlled intraocular pressure at the last examination. CONCLUSION: Mini-trabeculectomy in eyes with high risk of scarring was found efficacious and relatively safe. The relatively small peritomy, the tunnel approach, and the avoidance of radial incisions seem to offer important advantages over the standard trabeculectomy.

[Prognostic factors and surgical results in traumatic cataract].

The visual outcome in 23 men and 2 women with traumatic cataracts was analyzed retrospectively. Their average age was 33 and they ranged from 10 to 69 years. Surgical results were either very good or very poor. Associated retinal injuries significantly decreased final visual acuity (p = 0.001). Those with initial visual acuity restricted to finger counting had better visual results than those with initial visual acuity restricted to light perception (p = 0.01) and hand motions (p = 0.02). Usually the lens was removed via the pars plana; the most common mode of optical correction was contact lenses.

[Motor vehicle accidents and eye injuries].

The medical records of 24,632 patients treated in our surgical emergency service over a 3-year period were reviewed to determine the frequency and characteristics of ocular trauma caused by motor vehicle accidents (MVA). MVA-related injuries accounted for 13.9% of all visits to the service and involved 1106 of the patients (33%), of whom 77% were young males. At least 1 pathological finding was found in 858 (77.6%) and 169 (15.2%) were admitted. 16 patients sustained very severe ocular injuries which resulted in poor vision.

[Occupational accidents and eye injuries treated at the Rambam Medical Center].

To determine the prevalence of occupation-related eye injuries, we analyzed the records of 24,632 patients treated at our emergency surgical department over a 3-year period. Occupational accidents accounted for 17.6% of such cases. A third of them (1374 patients) were referred to the ophthalmic emergency room for further examination. In 89% (1223) of these, at least 1 pathological ocular finding was detected, and 8.3% (114) of them were hospitalized. Penetrating eye injuries were found in 5.2% (72). The commonest eye injury was corneal foreign body found in 42.8%.

Purtscher's retinopathy associated with mandibular fracture: a case report.

This report describes irreversible deterioration of vision after Purtscher's retinopathy associated with a fractured mandible. This rare phenomenon will be discussed, its literature will be reviewed, and its possible etiology will be suggested.

[Incidence of sports-related eye injuries].

The incidence of sports-related eye injuries was analyzed retrospectively for 1991-1993. It was fairly steady at about 2% of all eye casualties annually. 21% of those with sports-related eye injuries required hospitalization. The commonest pathological findings were corneal erosion (32%), eye lid injuries (27%), hyphema (19%) and macular edema (3%). Most eyes were injured during soccer (37%) and basketball (27%) games, the most popular sports in Israel.

Recurrent retinal artery obstruction as a presenting symptom of ophthalmic artery aneurysm: a case report.

BACKGROUND: Retinal artery obstruction is an ophthalmic emergency requiring immediate treatment. Recurrent episodes are the result of thromboembolic seeding and necessitate diagnostic efforts to find a possible source for this seeding. The most common sources of such seeding are the valves of the heart and the carotid arteries. CASE REPORT: We describe a case of a 25-year-old man who had recurrent episodes of retinal artery obstruction due to embolic spread. DISCUSSION: We suggest the origin of the embolic spread to be a post-traumatic ophthalmic artery aneurysm. The immediate and long-term treatment given to the patient are described, the present case is compared to earlier reports, and the unusual clinical picture and suggested treatment are discussed.

Excessive water drinking and cataract formation: a case report.

We report a case of a 46-year-old man who developed mature cataract in one eye and nearly mature cataract in his other eye over a 14-month period. No genetic, traumatic, or toxic etiology or intraocular pathology or history of irradiation were present. The patient had intentionally been drinking 15 liters of water a day for 11 months, up until 3 months prior to his admission, and 5 liters a day thereafter, until his admission. During his hospitalization he was found to suffer from insulin-dependent diabetes mellitus. The rest of his medical work-up was found to be normal. We suggest that the huge water overload put on his lens played a role in the premature and rapid cataract formation.
