Randomized clinical trial of the 350-mm2 versus the 500-mm2 Baerveldt implant: longer term results: Is bigger better?

OBJECTIVE: To report the longer term results of a randomized, clinical trial comparing the 350-mm2 and the 500-mm2 Baerveldt glaucoma implants. DESIGN: Extended follow-up on a randomized, controlled trial. PARTICIPANTS: Between March 1991 and April 1993, 107 patients with uncontrolled intraocular pressure (IOP) due to non-neovascular glaucoma associated with aphakia, pseudophakia, or failed filters were randomly assigned for surgical placement of either the 350-mm or the 500-mm2 Baerveldt implant at the Doheny Eye Institute. METHODS: A random-numbers table was used to assign each patient to one of the two groups. Preoperative IOPs and visual acuities were recorded. Clinical records were reviewed to ascertain postoperative IOPs, visual acuities, number of medications used, and implant-related complications that occurred throughout the follow-up period. MAIN OUTCOME MEASURES: Success was defined as IOP of 6 mmHg or greater and of 21 mmHg or less in two or more consecutive follow-up visits without further glaucoma surgery or loss of light perception attributable to glaucoma. RESULTS: The overall success rates were 87% for the 350-mm2 group and 70% for the 500-mm2 group (P = 0.05). Average follow-up was 37 months (range, 1-76 months) for the 350-mm2 group and 34 months (range, 5-77 months) for the 500-mm2 group. The life-table success rates declined over time for both implant groups, from a high of 98% for the 350-mm2 group and 92% for the 500-mm2 group at 1 year to a cumulative success rate of 79% for the 350-mm2 group and 66% for the 500-mm2 group at 5 years. Visual acuities were better or remained the same in 50% of the patients in the 350-mm2 group and 46% of those in the 500-mm2 group. Complications during the 5-year follow-up were also statistically similar. CONCLUSIONS: The longer term results show that the 350-mm2 Baerveldt implant is more successful than the 500-mm2 implant for overall IOP control. Interval comparisons indicate a higher rate of success for the 350-mm2 implant in the first, second, third, fourth, and fifth years of implantation. Visual acuities, implant-related complications, and average IOPs were statistically indistinguishable between the two groups.     

Episcleritis in childhood

OBJECTIVE: To describe the characteristics and systemic disease associations of episcleritis in childhood. DESIGN: Retrospective, observational case series. PARTICIPANTS: Twelve children diagnosed with episcleritis between July 1981 and June 1998. METHODS/TESTING: Complete eye and systemic evaluations. MAIN OUTCOME MEASURES: Characteristics of episcleritis and presence and nature of concurrent systemic disease. RESULTS: The 12 children (10 boys and 2 girls) ranged in age from 13 months to 16 years. Five children had bilateral simple episcleritis, one had bilateral nodular episcleritis, and six had unilateral simple episcleritis. The eye examination was otherwise normal and recovery was uneventful in all cases. Six of the nine children older than 5 years of age had one of the following rheumatologic diseases: systemic lupus erythematosus, juvenile rheumatoid arthritis, spondyloarthropathy, inflammatory bowel disease, rheumatic fever, or polyarteritis nodosa. All three children younger than 5 years of age had simple episcleritis, an antecedent viral illness, and presented within 2 months of each other. CONCLUSIONS: Episcleritis is a rare occurrence in childhood, especially in children younger than 5 years of age. In older children, it is frequently associated with rheumatologic disease.     

Comparative surface thrombogenicity of implanted vascular grafts.

In order to study the comparative thrombogenicity of neointimal surfaces that develop with three types of vascular graft materials (ultralightweight knitted dacron, knitted dacron external velour, and expanded Teflon), 36 female mongrel dogs had their infrarenal aortas alternately replaced with one of the three grafts. At the end of 3 or 6 months, the grafts were removed and the surface thrombogenicity of the neointimal surface was determined. Each graft was examined visually and microscopically for evidence of “healing.” At 6 months the external velour graft is lined more frequently than the other two grafts. The external velour graft has a markedly better incidence of cellular healing noted microscopically than the other two grafts at both time intervals. While the expanded Teflon has an initially lower surface thrombogenicity (probably due to the characteristics of Teflon surface), at 6 months, the velour graft has the lowest surface thrombogenicity. This is most likely due to cellular healing. Of all the completely lined grafts at both time intervals, the surface thrombogenicity of the velour grafts was most like that of the normal aorta. The velour graft appears to develop the least thrombogenic neointimal surface while becoming most frequently healed with a cellular neointimal surface.
