Objective To evaluate the effects of surgical treatment for severe ocular rupture with blood staining of cornea and non-light perception , and analyze the relative factors. Methods Seven severely rup tured eyes of 7 patients with blood staining of cornea and non-light perception underwent second-stage penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis. All injured eyes had blood staining of cornea, hemorrhage in anterior chamber and vitreous, and choroidal and retinal detachment before the second-stage surgery. The average interval of the two surgical stages was 18 days (12-21 days). The preoperative visual acuity was non-light percept ion in all injured eyes with the mean intraocular pressure of 3 mm Hg (1 mm Hg =0.133 kPa) (2-5 mm Hg).The mean follow-up period was 12 months (6-30 months). Results The postoperative visual acuity was better than light perception in 5 eyes with the best corrected visual acuity of light perception to 0.06. The retina was attached in 5 eyes (5/7). The mean postoperative intraocular pressure was 12 mm Hg(5-15 mm Hg)which was significantly higher than the preoperative one (Plt;0.05). Postoperative complications mainly included temporary intraocular hypertension (1 eye), corneal neovasculariza tion (4 eyes), cornea rejection (4 eyes), and ocular atrophy (2 eyes). Conclusion Penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis is a safe and effective method in treating severe ocular rupture with blood staining of cornea and non-light perception.

Objective To find out about the characteristics and prognosis of retinal detachment due to ocular contusion.Methods The clinical data of 36 patients(36 eyes)with retinal detachment due to ocular contusion were retrospectively analyzed.Results There were 3 eyes(8．3％)with huge retinal hole(≥90°)，4 eyes(11．1％)oral tear of ora serrata retinae，4 eyes(11．1％)with macular hole，3 eyes(8.3％)with tractive retinal detachment，and 22 eyes(61．2％)with retinal hole(lt;90°)at other positions(including temporal peripheral hole in 9，nasal peripheral hole in 5，and posterior polar hole in 8).Proliferative vitreoretinopathy(PVR)was found in a11 patients withConclusions Retinal detachment due to ocular contusion often go with PVR．The interval from contusion to retinal detachment varies from days to months.Visual prognosis can be good when retinal detachment is diagnosed and treated in time． (Chin J Ocul Fundus Dis，2004，20：1-66)
PURPOSE: Determining the efficacy of vitrectomy in explosive injuries of eye globes and assessing the curcept concept of enucleation for severe traumatized eyes. METIIODS: Clinical records were reviewed on 36 consecutive patients(44 eyes)with severe explosive eyeball injuries. RESULTS:The injuries were caused by explosion of detonator (10 eases), fire-crackers(7 cases) ,explosive and guns(19 cases). Ten eyes(22.7%)were ruptured. Fourty eyes(90. 9%)underwent vitrectomy for posterior segment injuries including vitreous hemorrhage,intraocular foreign bodies, endophthalmitis, and retinal detachment more than 2 weeks after trauma and primary wound repair. Postoperative visual acuity improved in 25 eye(62.5%) ,was stable in 11 eyes(27.5%) ,and decreased in 4 eyes(10%). Final vision was 0. 02 or better (up to 0.7)in 20 eyes(47.6%). No more enucleation was performed except two ruptured eyes (4.5% ) removed in primary clinical units. CONCLUSION :The results suggest that primary wound repair with microsurgery and secondary vitrectomy may reconstruct the eyeball and restore visual functions.at least partially.in the majority of eyes,even though the explosive ocular injuries often induce severe damages and eyeball rupture. It is.thus,recommended that primary enueleation of traumatized eyes should not be performed with an occasional exception. （Chin J Ocul Fundus Dis,1996,12: 169-171）
Purpose To observe the changes of choroidal circulati on and the retinal lesions caused by ocular contusion with indocyanine green ang iography (ICGA). Methods ICGA examination was performed on 30 cases (30 eyes) of various traumatic condition in conjunction with fundus fluorescein angiography (FFA). Results FFA of 19 cases (63.3%) showed the hypofluorence in quadrant or whole disc in accordance with the area of delayed filling of choroid. Twentysix cases (86.2%) showed d efected choroidel perfusion in ICGA,among them 16 cases showed localized delayed perfusion, in which the shortest perfusion time was 1 min 50 s and the l ongest time was 5 min.43 s,and 10 patients showed localized perfusion defect,and reversed filling time of retinochoroid vessels in 6 patients. Five cases (16.6%) had delayed filling time in both choroidal and central retinal vessels . Damage of retinal pigment epithelium was found in the areas of choroidal abnor mal perfusion. Conclusion ICGA combined with simultane ously FFA, is valuable in evaluating blunt injury of the ocular fundus and ben eficial to its diagnosis and treatment.

Objective To probe the clinical character,the histopathological classification and misdiagnoses of intraocular tumors. Methods The clinical and pathological data of 359 patients with intraocular tumor diagnosed clinically between 1980～2000 were retrospectively analyzed. Results There were 300 cases of malignant tumor and 23 cases of benign tumor respectively. Non-oncologic malady and benign tumor misdiagnosed as tumor or malignant tumor were 40 cases. The two leading malignant tumors were retinoblastoma and melanoma. Conclusion The clinical and pathological analysis of intraocular tumor is beneficial to the correct clinical diagnosis and treatment. (Chin J Ocul Fundus Dis,2002,18:28-30)
The opportunity of vitrectomy for opening eyeball injury is one of the important factors affecting the prognosis. Anterior segment wound repaired by routine suturing needs following and continuous treatment with vitrectomy. The key technique of the following treatment should be the debridement of the inside of wound and expurgation of the surrounding tissues adjacent to the wound, and the emphasis should be put on retinal reattchment and stable repairment.
Objective To explore the therapeutic value and effects of relaxing retinotomy for perforating traction retinal detachment(PTRD). Method A retrospective survey was done in 21 patinets (21 eyes) with PTRD who underwent vitrectomy combined with relaxing retinotomy in our hospital from 1998 to 2001.Results The retinae were completely reattached in all 21 cases. The visual acuity of 12 patients (57%) was counting finger, and the best visual acuity was 0.05. Among the 18 patients who were followed up for 6 to 25 months, 14(77.8%) remained retinal reattachment. Conclusions Relaxing retinotomy is effective for anatomic reattachment of PTRD, especially to the patients with retinal incarceration and severe proliferative vitreoretinopathy.

OCT angiography (OCTA) is a fast, noninvasive and quantifiable new technique, which is especially suitable for long-term follow-up in patients with hereditary retinochoroidal degeneration, such as retinitis pigmentosa, Best vitelliform macular dystrophy, adult onset foveomacular vitelliform dystrophy, doyne honeycomb retinal dystrophy, choroideremia and Stargardt disease. During the follow-up, clinicians can find the subtle signs that explain disease development from the blood flow imaging, quantitatively describe the vascular density, timely detect and treat choroidal neovascularization. It is significant to explore the etiology and monitor the course of these diseases. With the development of more treatments for these diseases, OCTA parameters can also be used as indicators to evaluate and compare different therapeutic effects. In the future, more quantitative indicators of OCTA will be applied to evaluate the course of hereditary retinochoroidal degeneration, and provide valuable basis for early diagnosis and treatment.
