Abstract Details
Purpose:
To analyse the outcomes (anatomical and functional) of tenonplasty in serious ocular thermal injuries (Grade 3 to 6 Dua's Classification) associated with scleral or sclerocorneal ischemia.
Setting:
Disha Eye Hospitals Private Limited, Barrackpore, Kolkata, india
Methods:
The records of 8 patients who underwent tenonplasty for thermal injury by molten metal from June 2014 till September 2015 were analysed retrospectively. 2 patients belonged to grade 3, 3 patients with grade 4 and 3 patients with grade 5 to 6 of Dua's Classification underwent tenonplasty at the site of ischemia. The time of intervention following injury, the need for revision surgeries, the time to complete epithelization, the procedures performed for ocular surface reconstruction and for visual rehabilitation and their outcome, both functional and anatomic, were analysed. Patients with < 1 year follow up were excluded.
Results:
7 eyes were unilateral and1 eye had bilateral thermal injury and all were male with mean age of 30.6 years. The mean time to presentation following chemical injury was 5.4 days. Tenonplasty with amniotic membrane transplantation (AMT) was performed as the primary surgery. Revision tenonplasty was required in 2 eyes, the mean time to complete epithelialzation of the ocular surface was 48.4days. Evisceration was performed in one eye for corneal infection in a patient with bilateral injury and other eye of that patient underwent further free oral mucosal autograft. Promising results were found in rest of the cases.
Conclusions:
In eyes with serious thermal burn, it is important to address scleral or sclerocorneal ischemia and accelerate reepithelialzation by tenonplasty. Sometimes we may have to repeat the procedure or go for limbal stem cell transplantation or oral mucous membrane grafting. When the globe integrity is saved and ocular surface is stable, we can plan further surgeries for better visual rehabilitation.
