Twentytwo patients with deviation of nasal septum were treated by modified septorhinoplasty. The main points in the modification were:(1) The incision was curved instead of "L" shaped. It would avoid the disadvantage of having tension on the suture line and poor exposure;(2) Using triangle osteotomy to correct deviation of nasal septum, it was less traumatic and lessbleeding and better correction. The results from followup were as follows:18 good and 4 fair. The techniques and advantages of the modified procedure were discussed.
Diabetic macular edema (DME) is the main cause of visual impairment in patients with diabetic retinopathy (DR). Currently, the main treatment methods of DME include intravitreal injection of anti-VEGF drugs, glucocorticoids and laser photocoagulation, but there are still some patients who do not respond or respond poorly to non-surgical treatments. Clinical and basic studies have confirmed that the abnormality of the vitreous-retinal interface plays an important role in the pathogenesis of DME. Par plana vitrectomy (PPV) can relieve macular traction, clear the vitreous cavity VEGF and other inflammatory cytokines, increase the vitreous cavity oxygen concentration, improve retinal oxygen supply, reduce retinal thickness of traction and non-traction DME, and improve patients' vision. However, how to choose and apply PPV to treat DME in specific practice, and to further improve the efficacy of PPV, including the innovation of surgical technology, combined treatment and the choice of surgical timing, still needs more clinical studies to explore.

Objectives To investigate the clinical characteristics and prognosis of syphilitic uveitis. Methods Clinical charts of 32 syphilitic uveitis patients were retrospectively analyzed. The diagnosis was confirmed by clinical and laboratory tests. There were 32 patients (50 eyes), 18 males and 14 females; the ages were from 21 to 62 years ole, with a mean age of 42 years old. Eighteen patients were bilateral. All patients had complete ocular examinations including visual acuity, intraocular pressure, slit-lamp biomicroscopy, ophthalmoscopy, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA). Results Inflammatory cells in the anterior chamber and corneal endothelium were present in 42 eyes. Thirty eyes showed congestion and swelling of optic discs. Yellowwhite lesions in the posterior pole were present in 18 eyes. No change in 6 eyes. FFA showed staining or hyperfluorescence of optic disc in 32 eyes, venous leakage in 34 eyes, and cystoid macular edema in 15 eyes．ICGA showed squamous or disseminative hypofluorescence damages in 26 eyes. All patients were treated with penicillin and glucocorticoids, 36 eyes had improved vision and fundus damage had abated. Conclusions Most syphilitic uveitis was panuveitis with retinal vasculitis. The prognosis is good with early diagnosis and timely treatment of this disease．
Objective To observe the therapeutic effect of photodynamic therapy (PDT) and transpupillary thermotherapy (TTT) on circumscribed choroid hemangioma (CCH).Methods Clinical data of 32 patients (33 eyes) with CCH diagnosed by ocular fundus examination, fundus fluorescein angiography (FFA),indocyanine green angiography (ICGA),optical coherence tomography (OCT) and Bultrasound examination were retrospectively analyzed.Before the therapy the selected cases had best corrected visual acuity (BCVA) of fingercounting/15 cm-0.2,the sizes of 2-10 disc diameter (DD) and serous retinal detachment.Twentyone patients (22 eyes) whose tumor located at the posterior pole except for the papillomacular bundle and arch ring area underwent TTT.The parameters of TTT included: Iris 810 nm infra red diode laser，7001200 mW,60 s,and 1-3 spots. Eleven patients (11 eyes) with tumor located at the posterior pole except for the papillomacular bundle and arch ring area underwent. After 15 minutes of intravenous injection with Visudyne, laser irradiation with the wavelength of 689 nm was performed with the time of 83-123 s. The followup period was 12-48 months with the mean of 25.6 months.BCVA and results of indirect ophthalmoscopy,fundus photogrphy,FFA,ICGA,OCT and B ultrasound examination were exanmined and anlyzed.Results In the 22 eyes in TTT group, the BCVA improved in 15 and kept unchanged in 7;the results of fundus examinations showed healed retina and atrophy tumor with greywhite organized scar;the results of FFA revealed no fluorescence leakage and scar fluorescence dyeing of the lesion in later period；the results of OCT indicated disappeared retinal detachment, completely absorbed subretinal liquid and increased reflection of choroid tumor with scar；the results of Bultrasound examination showed no retinal detachment and atrophy tumor.In 11 eyes in PDT group,the BCVA improved in 9, unchanged in 2;the results of fundus examinations showed atrophy tumor with pigmentation；the results of FFA revealed disappeared fluorescence leakage；the results of OCT indicated completely absorbed subretinal liquid；the results of B-ultrasound examination showed atrophy tumor.Conclusions Both TTT and PDT can make the tumor atrophy,improve BCVA or keep it still;but apply to different area.
ObjectiveTo observe the clinical effect of intravitreal ranibizumab (IVR) combined with vitrectomy in treating proliferative diabetic retinopathy (PDR). MethodsThis is a prospective non-randomized controlled clinical study. A total of 62 patients (70 eyes) who underwent vitrectomy for PDR were enrolled and divided into IVR group (30 patients, 34 eyes) and control group (32 patients, 36 eyes).IVR group patients received an intravitreal injection of 0.05 ml ranibizumab solution (10 mg/ml) 3 or 5 days before surgery. The follow-up time was 3 to 18 months with an average of (4.5±1.8) months. The surgical time, intraoperative bleeding, iatrogenic retinal breaks, use of silicone oil, the best corrected visual acuity (BCVA) and the incidence of postoperative complications were comparatively analyzed. ResultsThe difference of mean surgical time (t=6.136) and the number of endodiathermy during vitrectomy (t=6.128) between IVR group and control group was statistically significant (P=0.000, 0.036). The number of iatrogenic retinal break in IVR group is 8.8% and control group is 27.8%, the difference was statistically significant (χ2=4.154, P=0.032). Use of silicone oil of IVR group is 14.7% and control group is 38.9%, the difference was statistically significant (χ2=5.171, P=0.023). The incidence of postoperative vitreous hemorrhage in 3 month after surgery was 11.8% and 30.6% respectively in IVR group and control group. The differences were statistically significant (χ2=3.932, P=0.047). The 6 month postoperative mean BCVA of IVR group and control group have all improved than their preoperative BCVA, the difference was statistically significant (t=4.414, 8.234; P=0.000).But there was no difference between the mean postoperative BCVA of two groups (t=0.111, P=0.190). There was no topical and systemic adverse reactions associated with the drug after injection in IVR group. ConclusionsMicroincision vitreoretinal surgery assisted by IVR for PDR shorten surgical time, reduces the intraoperative bleeding and iatrogenic retinal breaks, reduces the use of silicon oil and the postoperative recurrent vitreous hemorrhage. But there was no significant relationship between vision improvement and IVR.
ObjectiveTo evaluate the efficacy of vitrectomy with internal limiting membrane peeling without intraocular tamponade in the treatment of myopic foveoschisis. MethodsTwenty-three eyes of 23 patients with myopic foveoschisis underwent vitreoretinal surgery were analyzed retrospectively. All the patients had undergone the examinations of best corrected visual acuity (BCVA), intraocular pressure, slit lamp microscope, direct ophthalmoscope, A or B ultrasonic scan and optical coherence tomography(OCT).The mean BCVA was 0.02-0.4, mean diopter was (-14.1±3.8) D, mean axial length was (28.8±1.5) mm, mean central fovea thickness (CFT) was (573.2±142.8) μm. A standard 3-port pars plana vitrectomy (25-gauge system) was performed in all patients. There was no tamponade at the end of the operation. The follow-up varied from 6 to 28 months. The visual acuity, CFT, retinal reattachment and the complications were observed. ResultsAt the latest follow up, there were 16 eyes (69.6%) were anatomically reattached, 4 eyes (17.4%) were partly anatomically reattached, 3 eyes (13.0%) were not reattached. Postoperative BCVA improved in 22 eyes (52.2%), unchanged in 9 eyes (39.1%), and decreased in 2 eyes (8.7%). No ocular complications such as macular hole, fundus hemorrhage, low or high intraocular pressure, endophthalmitis were found. ConclusionVitrectomy with internal limiting membrane peeling without gas tamponade can effectively treat myopic foveoschisis without ocular complications.
ObjectiveTo compare clinical outcomes in eyes with macula-off rhegmatogenous retinal detachments (RRD) with peripheral breaks managed by surgical protocols that result in either complete (CSFD) or partial subretinal fluid drainage (PSFD). MethodsFollowing the clinical detection of a macula-off RRD with peripheral retinal breaks, patients were offered the opportunity to enroll in the study, and those patients who signed the consent were evaluated for eligibility based upon the inclusion and exclusion criteria for this clinical study, and if fully eligible they were assigned prospectively to one of the two surgical designs (PSFD or CSFD, 1:1) using a random number table. Seventy-two eyes of 72 patients were enrolled and studied. Patients were treated with 25G plus vitrectomy, endolaser or transscleral cryopexy, either complete (n=36), or partial (n=36) subretinal fluid drainage, and 14%C3F8 (PFO) was used for intraocular tamponade. After surgery, all patients were kept in a supine position for 24 hours, and then in a clinically optimal position for 6-10 days. The study patients were examined at 1, 3 and 6 months after surgery with thorough ophthalmic examinations. Macular optical coherence tomography (OCT) imaging was acquired in 1 month. Anatomical and visual outcomes as well as intra-operative and postoperative complications of the two groups were compared. Furthermore, the persistence of subfoveal fluid in OCT images and the symptoms of distortion at 3 months were measured and recorded. The primary study endpoint of anatomic retinal reattachment for each group was based upon the 6-month time-point. ResultsThe preoperative baseline characteristics between the two groups were not significantly different. The single-operation success rates were 88.9% and 91.6% respectively for the CSFD and the PSFD groups (χ2=0.158, P>0.05). The mean best corrected visual acuity (BCVA) at 6 month endpoint were 0.99±0.52 minimum resoluation angle in logarithmic (logMAR) for the CSFD group and 1.07±0.34 logMAR for the PSFD group(t=0.580,P=0.564). The mean operative time was longer in the CSFD group (62.25±4.32) minutes than that in the PSFD group (47.9±5.0) minutes (t=0.580, P=0.564). seven of 29 (24.1%) phakic eyes in the CSFD group had lens injury during SRF drainage, and none of the 31-phakic eyes in the PSFD group sustained lens damage. Residual PFO was present in 6 of 36 CSFD cases (16.7%). Successful retinal reattachment after primary surgery was achieved in 33) PSFD eyes and in 32 CSFD eyes based upon OCT imaging at 1 month demonstrated reattached foveae with no residual subfoveal fluid. Among these patients, 22 patients (62.5%) in the CSFD group and 23(69.7%) patients in the PSFD group reported distortion in the operated eye or/and a difference in image size between the two eyes at the 6 month visit (P=1.00). ConclusionsPartial subretinal fluid drainage during pars plana vitrectomy for the repair of macula-off RRD with peripheral breaks is effective. The success rates are not statistically different. Additionally, PSFD procedures can simplify the surgery procedure, shorten operative time and, and to some extent, reduce the incidence of complications relevant to the CSFD approach.
