Abstract

Abstract: Purpose: To compare, in a larger study population, the outcomes of strabismus surgery in patients who either had the scleral explant (EX) retained or removed after surgery for retinal detachment. Methods: A comparative retrospective study includes data from 2 centres. Surgical outcome, motor success, sensory success, the number of secondary operations for strabismus and complications were compared between the two groups. Motor success was defined as horizontal deviation of ≤6 prism diopters (PD) and vertical deviation of ≤6PD. Sensory success was defined as no diplopia without use of prism. Results: Forty‐seven patients were included in the study; 70% had retained the EX and 74% had vertical strabismus. Horizontally, the final alignment was equal between the 2 groups, 4 PD vs.5 PD in the EX removed group. The patients with retained EX were referred with a significant lower mean vertical deviation and had a significant lower post‐operative mean vertical deviation of 2 PD vs. 3 PD in the EX‐removed group. The rates of motor success (76% vs. 71%) and sensory success (79% vs. 93%) did not differ significantly between the EX‐retained and EX‐removed groups. No patients underwent more than 2 operations. Two complications occurred in the EX‐retained group: a subconjunctival cyst and an exposed EX. In the EX‐removed group, 2 patients with retinal re‐detachment were found in the follow‐up period. Conclusion: Good surgical outcomes including high motor and sensory success were obtained regardless of the presence of the EX. Retinal re‐detachment was observed in two patients with previously removed EX.
