Secondary intraocular lens implantation in aphakic eyes following vitrectomy

Objective To evaluate the visual results,surgical tec hnique and safety of secondary intraocular lens (IOL) implantation in aphakic eyes following vitrectomy and lensectomy for complicated ocular trauma or retinal detachment． Methods The clinical records of 3 2 cases (32 eyes),received these surgeries during November 1996 and December 1999,were reviewed retrospectively.During the secondary operation，intraocular infu sion through the pars plana was performend and the type of IOL was chosen based on the integrity of lens capsule. Results The study included 30 eyes suffering from trauma (foreign bodies in 15 eyes,penetrating injury with traumatic endophthalmitis and with vitreous hemorrhage in 6 eyes respectively, blunt trauma with lens dislocation in 3 eyes),and 2 eyes with primary retinal detachment.Those eyes all received vitrectomy,lensectomy,and/or remova l of foreign bodies and corneal suture.The interval of two operations ranged from 1 to 16 months with an average of 6.8plusmn;3.7 months.Posterior chamber IOL was implanted in the ciliary sulcus in 25 eyes with a whole or 2/3 of lens capsule,trans scleral suture fixation of IOL in 5 eyes,anterior chamber IOL and IOL with artificialiris in one eye respectively.Silicone oil was removed in 5 eyes duri ng the secondary operation.Post-operative visual improvement was achieved in 29 eyes.Main complications were corneal edema and low intraocular pressure after operation. Conclusion Intraocular infusion and proper IOL implantation during the secondary operation following vitrectomy can provide selected aphakic eyes with better visual recovery. (Chin J Ocul Fundus Dis, 2001,17:96-98)

女性Eales病八例

目的：評價女性Eales病的臨床特征及對持久的玻璃體出血和牽拉性視網膜脫離的玻璃體手術效果。 方法：復習本科1993年4月至1994年12月經玻璃體手術治療的該病患者的病歷記錄。 結果：8例（11只眼）女性患者占同期該病患者的22%，年齡19~35歲，平均病史10.8個月，急性發病后持久出血及視力嚴重喪失，伴視盤和周邊部新生血管膜及黃斑水腫。10只眼玻璃手術后視力明顯改善8只眼，0.2~1.0者6只眼。1眼有早期周邊部血管白鞘，經氬激光光凝。 結論：女性Eales病的特點可能包括年齡輕，病史短，急性發作，有持久出血和新生血管膜形成。玻璃手術能有效改善多數眼的視力。 （中華眼底病雜志，1996，12：51-52）

Retinal vein occlusion with vitreous hemorrhage，neovascular membranes and traction retinal detachment treated with vitreous surgery and endolaser

Purpose To evaluate the efficacy of vitreous surgery and endolaser in a series of patients with retinal vein occlusion(RVO)with vitreous hemorrhage,neovascular membranes(NVM) and/or traction retinal detachment(TRD). Methods Clinical records were reviewed on 37 consecutive patients(38 eyes)who underwent vitreous surgery and endolaser for RVO with persistent vitreous hemorrhage,NVM and/or TRD.There were 19 patients(20 eyes)with retinal branch vein occlusion (BRVO)and 18 patients(18 eyes)with central retinal vein occlusion(CRVO). Results NVM and TRD were confirmed during operation in 27 and 23 eyes,respectively.Visual acuity improved postoperatively in 34 eyes(89.5%)including 22 eyes with 0.1 or better vision,and 4 eyes remained unchanged.CRVO group had longer history and less visual improvement after surgery. Conclusions Vitreous surgery and endolaser photocoagulation can improve the outcome in the majority of patients with RVO with vitreous hemorrage,NVM and/or TRD. (Chin J Ocul Fundus Dis,1998,14:3-6)
