Clinical Evaluation of Pseudophakic Retinal Detachment

ABSTRACT

PURPOSE: To evaluate the clinical characteristics of pseudophakic retinal detachment(RD) as RD is the most common sight-threatening complication after cataract surgery. METHODS: We analysed retrospectively the clinical characteristics of 22 pseudophakic RD patiens(23 eyes) which had been operated from January 1993 to December 1997 and followed for 6 months or longer at the Gyeongsang National University Hospital. RESULTS: The average age of the patients was sixty-three and male predominated 19 eyes(82.6%). According as types of IOL implantation included 14 eyes with posterior chamber IOL, 7 eyes with sclera-fixated IOL, 2 eyes with anterior chamber IOL, and 16 eyes(70%) occurred the posterior casule rupture. The interval between IOL implantation and the development of RD was 9.6 months on average and 78% of eyes developed RD within 1 year. In eyes with sclera-fixated IOL, the interval was shorter than others, In cases with ruptured posterior capsule, RD occurred earlier than those with intact posterior capsule. Retinal breaks were principally located in the upper quadrants in 12 eyes(63%) and horseshoe tear was most commmonly encountered. RD involving 3 or more quadrants was observed in 12 eyes(51%) of patients, and macular detachment in 18 eyes(78%). Anatomic success achieved in 83%. The most common cause of the failure was the development of proliferative vitreoretinopathy. Visual results in eyes with ultimate anatomic success of RD repair improved 0.5 or more in 80% if the macula was not involved and in 14.2% if the macula was involved. CONCLUSION: We thought that thorough fundus examination is neccessary during the follow-up of pseudophakic eye with posterior capsule rupture and sclera-fixated IOL after cataract surgery.
