ABSTRACT
Chemical burns represent blinding ocular injuries and constitute an ocular emergency requiring immediate assessment and initiation of treatment. The majority of patients are of young age groups and exposure will occur anywhere as an accident and in association with criminal assaults too. Alkali injuries occur more frequently. Chemical injuries of the eye produce extensive damage to the conjunctiva, cornea, anterior segment and limbal stem cells resulting in unilateral or bilateral visual impairment. This article reviews the emergency management to improve the prognosis of patients with chemical injuries
ABSTRACT
Background:Pterygium is degenerative condition of the subconjunctival tissue which proliferates as vascularized granulation tissue and is characterized by formation of a triangular fold of conjunctiva encroaching on the cornea leading to visual impairment, restriction of ocular motility, chronic in?ammation and cosmetic concerns. Surgical removal is the treatment of choice, but recurrence can be a problem. Now, Fibrin glue is being tried since few years to secure grafts in place of the sutures. The objective of this study was to compare duration of surgery, immediate postoperative complications which includes an in?ammation, subconjunctival haemorrhage, patient comfort, graft stability between the uses of ?brin glue versus sutures. Methods:A total of 40 patients having primary pterygium were included in the study. 20 patients were underwent pterygium excision surgery and conjunctival autografting using absorbable vicryl 8-0 suture and 20 patients underwent pterygium excision surgery and conjunctival autografting using ?brin glue. These 2 groups were compared in terms of duration of the surgery, in?ammation, degree of postoperative discomfort, subconjunctival haemorrhage and graft stability at postoperative day 1. Results:The mean surgery time in ?brin glue group was 15 minutes and mean surgery time in suture group was 28 minutes (p=0.000). Fibrin glue group had signi?cantly lesser in?ammation (p=0.001) as well as postoperative discomfort (p=0.000) compared to suture group at postoperative day 1. There was no signi?cant difference found in the degree of subconjunctival haemorrhage between the ?brin glue versus sutures groups (p=0.887 and p=0.797 at day 1). The grafts secured with ?brin glue were as stable as those secured with the sutures (p=0.745, 0.644 at day 1). Conclusion:The ?brin glue group in conjunctival autografting had signi?cantly less surgery time, which also produces signi?cantly less postoperative discomfort as well as in?ammation with grafts being as stable as those secured with sutures. Fibrin glue can be used regularly if patients can be pooled together and operated on, by making it cost effective procedure
