Use of biodegradable collagen-glycosaminoglycan copolymer matrix implant to reduce postoperative fibrosis in strabismus surgery

Abstract

The occurrence of restrictive strabismus after conjunctival surgeries is widely described in the literature. Fibrosis causes adherence of the conjunctiva to the Tenon's capsule, intermuscular membrane, adipose orbital tissue, sclera, and extraocular muscle tissue. Fibrosis causes adherence of the conjunctiva to the Tenon's capsule, intermuscular membrane, adipose orbital tissue, sclera, and extraocular muscle tissue. We report a case of the use of a biodegradable collagen-glycosaminoglycan copolymer matrix implant (Ologen®) as an alternative adjuvant, used as a spacer to mechanically separate the subconjunctival and episcleral tissues to prevent fibrosis in a patient undergoing a surgical correction for a strabismus with a restrictive component due to previous surgeries of pterygium excision.

Factors Associated and Management of Functional Failure after External Dacryocystorhinostomy at Zonal Tertiary Hospital

“…This study has shown that there is a quite high proportion of external DCR's done on children between the ages of 0-18 years (44.5%) this is similar to a study done here at KCMC but this had a small sample size [12]. But slightly high as compared to a study done from Nepal which establishes that only 17.2% of external DCR cases done were on patients under 20 years of age [13], a study from Iran found this figure to be only 12% and study from Ethiopian patients found that only 10% of operated cases were under the age of 14 [14][15][16][17][18].…”
