Study finds, Efficacy of Posterior Scleral Contraction in th
A Study was conducted to evaluate efficacy of posterior scleral contraction for macular hole with retinal detachment in high myopia.

73 macular hole with retinal detachment eyes were treated with posterior scleral contraction. A strip was sent across inferior–temporal scleral surface to posterior pole, then two ends were led out from nasal-inferior to temporal-superior areas. It was tightened to contract posterior sclera with designed axial length shortening after aqueous humor was drained from anterior chamber.

Results:
--Axial length was 30.01 ± 2.27 mm at preoperation and shortened by 2.57 ± 0.82 mm intraoperatively.

--At final postoperation, maintained axial length shortening was 1.87 ± 0.92 mm. 46 eyes recovered as type I, 26 eyes as type II, and 1 eye unrecovered.

--Postoperative best-corrected visual acuity was better than preoperative one with correlation and consistency between two.

Finally, posterior scleral contraction with axial length shortening was successful in recovering a macular hole with retinal detachment. While independent of recovery types, visual improvement was attained, correlated, and consistent with preoperative best-corrected visual acuity.
