Short-Term Changes of Immediate Postoperative Deviation after Lateral Rectus Recession for Intermittent Exotropia

PURPOSE: To assess the prevalence of short-term changes in immediate postoperative deviation, and to evaluate the relationship of these to clinical factors after lateral rectus recession for intermittent exotropia. METHODS: One hundred patients who had lateral rectus recession performed for intermittent exotropia and who had at least 3 months of postoperative follow-up were included in this study. RESULTS: The average angle of esodeviation on postoperative day 1 was 8.2 (-5 ~ +25) delta. The rate of surgical success (or=10delta on postoperative day 1 showed a higher chance of surgical failure due to overcorrection at postoperative 3 months (p=0.002). The preoperative deviating angle, type of exotropia, and combined oblique muscle surgery did not influence the outcome. CONCLUSIONS: An esodeviation of 10 ~ 15delta on postoperative day 1 was related to a good outcome at postoperative 3 months. Less esodeviation and smaller exotropic drift occurred in patients aged 10 years and older, so it is possible that an initial overcorrection of >or=10delta may remain for a long period of time in the older patient group.

Spontaneous Regression of Neovascularization at the Disc in Diabetic Retinopathy

Neovascularization at the disc (NVD) is the most serious complication in diabetic retinopathy, and leads to vitreous hemorrhage and tractional retinal detachment. We report two cases of spontaneous regression of NVD in proliferative diabetic retinopathy. Two men (31 and 46 years old) with diabetes had NVD in both eyes. They were treated with panretinal photocoagulation on the left eye first, but their right eyes went untreated, because they did not revisit our clinic for several months. Fortunately, on revisit, their neovascularization had disappeared a few months later in both eyes, including their untreated right eyes. We could not find any specific causes for the spontaneous regression of the new vessels.
