  • Treatment for familial exudative vitreoretinopathy

    Objective To observe the surgical effects of photocoagulation and vitrectomy on familial exudative vitreoretinopathy (FEVR). Methods The data from 32 eyes of 17 patients with FEVR diagnosed in our department from January 1997 to August 2005 were analyzed retrospectively. The methods of treatment had been chosen according to the disease extents. Seven eyes ( stage 1 in 2 eyes, 2A in 1 eyes, and 2B in 4 eyes) had undergone peripheral photocoagulation with the follow-up period of 6-108 months (the average was 20.29 months); vitrectomy had been performed on 13 eyes(stage 3B in 2 eyes,4A in 1 eyes, 4B in 6 eyes, and 5A in 4 eyes) with the follow-up period of 3-108 months ( the average was 20.65 months); 12 eyes had received none of the treatments due to the serious extents, age, and the selection of the patientsprime; relations. Results In 7 eyes treated with peripheral photocoagulation, the disease was stable and visual acuity remained unchanged during the follow-up period . In 13 eyes undergone vitrectomy, reattached retina was found in 12; visual acuity improved in 9, kept still in 3, and was unknown in 1 because of the patient prime;s noncooperation. Conclusion Photocoagulation may prevent the development of FEVR, and vitrectomy can promote the reattachment of retina and improvement of the visual acuity in patients with FEVR. These two treatments are effective on FEVR.  (Chin J Ocul Fundus Dis,2006,22:302-304)

  • Clinical research of retinopathy of prematurity in infants with very low birth weight

    ObjectiveTo evaluate the potential risk factors with incidence and degree of retinopathy of prematurity (ROP) in infants with very low birth weight.MethodsThe clinical data of 130 premature infants with birth weight ≤1500 g recorded in Peking University People′s Hospital from July 2002 to April 2004 were retrospectively analyzed.ResultsThere were 60 infants in ROP group and 70 infants in control group. The mean birth weight and gestational age was (1256.3±196.8) g and (29.583 3±1.543 6) weeks in ROP group, and (1337.8±146) g and (31.217 4±2.430 6) weeks in control group, respectively. In 39 ecdemic infants, 32 were found with ROP (82.1%, 1 with mild and 31 with severe ROP) while in 91 local infants, 28 were found with ROP (30.8%, 15 with mild and 13 with severe ROP). The time of the first examination in infants with mild ROP was (36.062 5±2.909 0) weeks, which was significantly earlier than (59.477 3±33.604 0) weeks in the ones with severe ROP. The time of the first examination and surgery was earlier in non vitrectomy group than in nonvitrectomy group.ConclusionLow birth weight is the high risk factor in ROP. Incidence of ROP is higher in ecdemic infants. The severity of ROP correlates with time of first examination, and the way of surgery is relative to time of the first examination and surgery.(Chin J Ocul Fundus Dis,2005,21:275-277)

  • Comparison between the intraocular pressure values measured by Goldmann tonometer and Tono-pen tonometer in patients undergone vitrectomy

    ObjectiveTo compare the results of intraocular pressure (IOP) values measured by Goldmann tonometer with which measured by Tono-pen tonometer, and to evaluate the feasibility of Tono-pen tonometer.MethodsA total of 120 patients were selected, including 60 who had undergone simple pars plana vitrectomy (PPV) and the other 60 who had undergone PPV with silicon filling. IOP of all of the patients was measured by Goldmann tonometer or Tono-pen tonometer 3 days after the operation, and the results of the two measurements were compared.ResultsThe mean IOP was (19.72±4.62) mm Hgin the patients measured by Goldmann tonometer and (19.69±4.60) mm Hg in patients measured by Tono-pen tonometer. There was no statistic difference of results between the two measurements (P>0.05). High correlation between the results of the two methods when the IOP was at 8 to 29 mm Hg was found. ConclusionsTono-pen tonometer is a simple method to measure the IOP of patients who have undergone PPV or PPV with silicon filling when their IOP is at 8 to 29 mm Hg.(Chin J Ocul Fundus Dis, 2005,21:303-305)

  • Effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage

    ObjectiveTo explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage.MethodsSeven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months).ResultsThe postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one (Plt;0.05). The postoperative complications mainly included fibrosis exudates in anterior chamber (7 eyes), intraocular pressure elevation 1-2 weeks after the operation (2 eyes), and postoperative suprachoroidcavity hemorrhage (2 eyes).ConclusionVitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy may be effective procedures for some cases of neovascular glaucoma combined with vitreous hemorrhage.(Chin J Ocul Fundus Dis, 2005,21:148-149)

  • The clinical analysis for secondary vitreous surgery

    Objective To investigate the causes of failure of the primary vitrectomy,sum up the experience for secondary vitreous surgery and improve the success rate of primary vitrectomy for complicated retinal detachment. Methods The records of a consecutive series of 60 patients(65 eyes)that underwent secondary vitreous surgery between 1997 to 1998 were retrospectively reviewed.The age of patient ranged from 9 to 63 years(mean 36),and the followup period ranged from 3 to 18 months(mean 10.5 months). Results The main causes of failure of the primary vitrectomy were postoperative recurrence of proliferative vitreoretinopathy(PVR),unwell closed retinal breaks,and intra-and postoperative complications.In 46 of 65 eyes the retina was reattached after secondary vitreous surgery(70.1%).Postoperatively,31 eyes (47.7%) had a visual acuity(VA)improved,16 eyes(24.6%)had a VA unchanged,and 18eyes(27.7%)had a VA reduced.Fifteen eyes(23.1%)had a VA of ge;0.05 and the best VA was 0.4.Thirty-nine eyes were followed-up from 3 to 18 months(mean 10.5).In 35 of 39 eyes,the retina was reattached(89.7%),26 eyes(40%)had a VA of ge;0.05,and 7 eyes(10.7%)were hypotonic. Conclusions The keys to the success of secondary vitreous surgery are to restore the mobility for retina by eliminating the PVR completely,and avoid intraoperative complicattions by choosing the appropriate closure procedure for retinal breaks and the suitable intraocular tamponades.

  • Clinical observation of scleral buckling in patients with retinal detachment with large or giant retinal hole

    Objective To analyze the surgical feasibility, operative key points and visual function recovery of scleral buckling in patients with rhegmatogenous retinal detachment (RRD) with large or giant retinal hole. Methods RRD patients with large or giant retinal hole who underwent scleral buckling in Chengdu Aidi Eye Hospital between January 1, 2019 and December 31, 2020 were retrospectively selected. The general data, complications and postoperative recovery of the patients were observed. Results A total of 344 inpatients (351 eyes) underwent scleral buckling with RRD, including 43 patients (43 eyes) with retinal detachment of large or giant hole. Among the 43 patients, there were 30 males (30 eyes) and 13 females (13 eyes); 42 cases were successfully operated and got retinal reattachment, and 1 failed. One week later, the patient underwent vitrectomy combined with silicone oil tamponade, and got retinal reattachment. No serious complications occurred in the patients after operation. The visual acuity of most patients improved after surgery. ConclusionsScleral buckling is still an effective method to treat RRD. It is still suitable for more patients as long as they are carefully checked before operation and the operators master the key points of operation. At the same time, more patients’ vitreous bodies can be preserved, and the normal structure and intraocular environment of the eyeball can be maintained.
