摘要

Paediatric cataract surgery is associated with several complications among which is high ocular inflammatory response. Conventionally immediate post-operative subconjunctival steroid with adjuvant systemic and frequent topical steroids have been used to control post-operative inflammation. Studies have reported the advantage of intracameral dexamethasone in decreasing postoperative inflammation. Aim: To evaluate the clinical outcome of intracameral dexamethasone in paediatric cataract surgery in Evangelical Church of West Africa (ECWA) Eye Hospital, Kano. Method: This was a prospective study of 694 paediatric cataract surgeries from January 2006 to December 2014. All the patients were given intracameral dexamethasone 0.4 mg (0.1 ml) immediately after surgery. Each patient had surgical intervention on one eye. Evaluation was done on first, third postoperative day, one week and four weeks later (follow up visits). Outcomes were measured on the fourth week post-operation. Examination of children was done with help of slit lamp for cells, flare or any other sign of inflammation. In case of non-cooperative children examination was done with microscope under sedation/general anaesthesia for fibrinous reaction, exudative membrane, posterior synechiae and red reflex. Results: There were total of 694 patients with age range of 0 to 11 years. Mean age of participants was 2.03 ± 2.5 years. The mean duration of cataract before presentation to the hospital was 5.7 ± 4.3 months with a range of 0 to 16 months. Post operative complications, likely to be associated with intracameral dexamethasone were corneal opacity (0.6%) and raised intraocular pressure (12.5%). In 31 patients (4.5%) there was no post operative complication. Conclusion: Intracameral injection of dexamethasone has a role in preventing immediate postoperative anterior uveitis in paediatric cataract but may not be without complication.
