Objective To quantitatively evaluate the long-term changes in biometric characteristics parameters after laser peripheral iridotomy (LPI) in primary angle closure suspect (PACS). Methods A prospective case series study. 40 PACS patients in Handan Eye Hospital, Hebei were enrolled in five years. LPI was performed in one eye selected randomly of every case (LPI group) , the other was as naturally control eye. Routine ophthalmic tests and A-scan examination were performed on both eyes at presentation、1 year and 5 year after LPI, including central anterior chamber depth (CACD),lens thickness (LT) and axial length (AL). Results Compared to before LPI, CACD was significantly deeper at 1 year, but more shallow at 5 year (all P<0.05). CACD in LPI group was more deeper than that in control group at 1 year, 5 year (P<0.05) . Within 5 years, CACD was grad-ually decreased, but the CACD at 5 year in the laser group was still bigger than that in the control group (P<0.05). LT in both team were thick gradually within 5 years (P<0.05) . Conclusions LPI can significantly deepen the central anterior chamber and delay the central anterior chamber shallow in PACS.

Objective To visualize the clinical features and investigate the major treatments and clinical cu-rative effects of vasoproliferative retinal tumor. Methods In these retrospective case series, 21 patients (22 eyes) were selected who were diagnosed as vasoproliferative retinal tumor between October 2005 and February 2015. The patients manifested as hemorrhage before or in the retinal. The patients were treated by different surgeries on the bases of ocular examinations such as B ultra-scan and fundus fluorescein angiography. Results Patients who were treated by intravitreal injection, radiation application, retinal freezing, laser photocoagu-lation or vitrectomy gained less fundus exudation and contraction tumors, with efficiencies of 50.00%, 50.00%, 66.67%, 83.33% and 77.78% respectively. Among which the effective rate of laser photocoagulation and vitrectomy were apparently higher than other therapies. Conclusions Photocoagulation and vitrectomy are good for the regression of vasoproliferative retinal tumor and can be applied clinically.

Objective To investigate the influence of excyclotorsion by inferior oblique (IO) recession versus anterior transposition. Methods A total of 31 cases (48 eyes) with paralysis of superior oblique (SOP) were reported. Recession of IO was performed in 36 eyes with SOP (group A) and anterior transposition of IO was performed in 12 eyes with SOP associated with dissociated vertical deviation (group B). Objective cycloposition was assessed by fundus photograph before and after surgery in all cases. The mean time of follow-up was 6.67 months. Results The fovea-disc angle (FAD) of pre-or post-operation were (14.57°±6.26°) and (9.50°±5.45°), respectively. In group A and group B, that were (10.25°±6.09°) and (5.75°±4.73°) respectively. The excyclotorsion was improved (5.07°±3.92°) and (4.50°±3.67°), respectively in two groups.

Objective To study the characteristics of vivo confocal microscopy after corneal collagen cross link, and to evaluate the efficacy of corneal collagen cross-linking for keratoconus therapy. Methods A total of 23 keratoconus patients (23 eyes) with corneal thickness no less than 400 μm were recruited in this study. Corneal epithelium of central 9 mm was removed mechanically under topical anesthesia, 0.1% riboflavin was applied. Then standard UVA/riboflavin corneal crosslinking was applied. VA, Slit lamp, anterior segment optical coherence tomography (AS-OCT), vivo confocal microscopy was examined and recorded. Results Imaging characteristics in AS-OCT: Preoperative corneal stroma was relatively uniform yellowish green and reflective, postoperative anterior corneal storma emerges relatively dense yellow and green high reflectance, posterior stroma was relatively loose green-based low reflection. Imaging characteristics in vivo confocal microscopy: Preoperative corneal stroma fibers wrinkles showed low reflective stripes, postoperative corneal storma showed high reflective stripes along the dark stripes, and it was more obvious in the anterior storm than the posterior stroma. Conclusions Vivo confocal microscopy shows clear morphological evidence in CXL. UVA/0.1% riboflavin corneal crosslinking achieve conductive riboflavin penetration, and it is safe and effective in the treatment of keratoconus.

Objective To investigate the changes in thickness of retinal nerve fiber layer (RNFL) and visual fields following the initial acute attack of acute primary angle closure glaucoma (APACG) within 1 year. Methods A prospective cohort study. 30 consecutively recruited patients with APACG were observed (the attacked eye was as the observed eye while the fellow eye as control). At 6 time points (after intraocular pressure controlled for 24 hour, 1 week, 1 month, 3 month, 6 month, 12 month), intraocular pressure (IOP), RNFL thickness and Humphrey perimeter were analyzed. Results Compared with the control group, the average RNFL thickness in the observed group were thicker at 24 hour and 1 week (P 0.05). The thickness of averaged RNFL was positively correlated with the MD (P <0.05). Conclusions The thickness of the RNFL in patients with APACG is diffusely increasing after the acute attack for the first time, which is gradually thinner with the time going. However,it is stable after IOP con-trolled for 6 months; Perimetric damaged is reversible at the 1 month after IOP controlled and there is no deterioration until the 1 year; For the optic nerve, the injury of morphology is consistent with the function.

Objective To investigate the relationship between macularstructure and visual acuity in patients with idiopathic macular membrane surgery. Methods A retrospective trail analyzed the data of 38 patients (38eyes). The best corrected visual acuity(BCVA), central foveal thickness(CFT), average macular thickness were measured and the correlations between BCVA, CFT and average macular thickness were investigated using Pearson correlation analysis. Patients were divided into two groups based on whether the Ellipsoid Zone (EZ) was irregular. The BCVA, CFT and average macular thickness of each group were also analyzed. Results The mean BCVA was improved to0.45 (SD 0.26) and the mean CFT regressed to 334.5um (SD 69.5).The preoperative BCVA was significantly correlated with preoperative average macular thickness and the final BCVA was correlated with final CFT. A linear relationship between the reduction of central foveal thickness and improvement of visual acuity was confirmed. The final BCVA of EZ intact group was better than EZ disrupted group. Conclusions CFT could be a useful prognostic factor after ERM surgery. It might be better to schedule surgery while the EZ remain intact.

Objective To compare the structure morphologyand visual function changes of surgery for idiopathic epimacular membrane(IEMM)withand without internal limiting membrane(ILM)peeling,in idiopathic macular membrane patients. Methods Aretrospective analysis wasmade for83 patients (84 eyes)with IEMM,according to different treatments divided into two groups,observation group: EMM peeling combined withILMpeeling;control group:single EMM peeling.Followed up for 2 to 12 months to observe the epimacular membranepeeling,macular edema,visual changes,and changes in visual acuity and foveal thickness for linear correlation analysis. Results Postoperative visual acuity improved significantly on both groups(P <0.05),epiretinal membrane were successfully stripped.Observation group:40 eyes of 40 cases of macular edema had a recurrent(2.5%);control group:43 cases 44 eyes of 5 recurrent macular edema(11.4%).Edema recurrent rate compared to the two groups was statistically significant(P <0.05),postoperative visual acuity improved margin and margin improvement in foveal thickness correlated positively(observation group,r=0.616,P=0.00;control group,r=0.462,P=0.01). Conclusions Vitrectomy combined internal limitingmembrane peeling cansignificantly improve the success rate and reduce the recurrence of edema and improve visual function,improve visual acuity better,changes in vision and central macular thickness with a positive correlation.
