OBJECTIVE: To build bridges between anti-α enolase antibody (anti-enolase 1 antibody, anti-ENO1 antibody) and common clinical and laboratory characteristics of systemic lupus erythematosus (SLE) and to analyze the role of anti-ENO1 antibody in the evaluation of SLE disease activity. METHODS: The SLE patients with retinopathy and without retinopathy were enrolled in the study, as well as healthy individuals whose gender and age matched with those of the SLE patients. Serum anti-ENO1 antibodies were measured using enzyme-linked immunosorbent assay (ELISA), presenting as intra-group positive rate and arbitrary units (AU) value. Clinical and laboratory data were obtained from medical records. RESULTS: The SLE retinopathy patients represented various fundus abnormalities. Ranked by percentage, the top three retinopathies were retinal hemorrhage (14/32, 43.75%), cotton-wool spots (8/32, 25.00%) and retinal vein occlusion (3/32, 9.38%). Among the 32 SLE retinopathy patients, 13 (40.63%) suffered from two or more fundus abnormalities. The positive rate and AU value of the SLE patients were higher than of the SLE patients without retinopathy (68.75% vs. 46.00%, P=0.043; 16.11%±10.35% vs. 12.06%±6.47%, P=0.045). Besides, the positive rate and AU value of the two SLE groups were both significantly higher than those of the healthy control group (P < 0.001). Compared with the SLE-without-retinopathy group, the systemic lupus erythematosus disease activity index (SLEDAI)-2000 of the SLE retinopathy patients were significantly higher than those of the SLE patients without retinopathy (17.41±4.25 vs. 9.48±5.35, P < 0.001). Dividing all the SLE patients into an anti-ENO1-positive group and an anti-ENO1-negative group, we found that anti-ENO1-positive was more likely to be correlated to developing fever and positive result of urine occult blood (P=0.011, P=0.042). Comparing with the patients with negative anti-ENO1 antibodies, the patients with positive anti-ENO1 antibodies had significantly higher erythrocyte sedimentation rate (ESR) [the median (range) was 29.50 (1.52-110.00) mg/L vs. 12.00 (4.00-101.00) mg/L, P=0.001], higher immunoglobulin G (IgG) [the median (range) was 14.30 (4.02-37.80) g/L vs. 10.46 (2.50-25.73) g/L, P=0.000 3], and higher blood platelet count (PLT) [(205.87×10⁹±67.98×10⁹) /L vs. (164.57×10⁹±69.57×10⁹) /L, P=0.008], as well as higher immunoglobulin A (IgA) [the median (range) was 2.85 (0.07-27.00) g/L vs. 2.05 (0.42-4.36) g/L, P=0.014]. CONCLUSION The positive rate and AU value of anti-ENO1 antibody suggested higher SLE disease activity and they were elevated in SLE and SLE retinopathy.

To observe corrected visual acuity and contrast sensitivity (CS) in patients with hypertensive disorders complicating pregnancy accompanied by fundus changes.
 Methods: Ninety-eight patients with hypertensive disorders complicating pregnancy and 50 healthy pregnant women underwent eye examination, including corrected visual acuity and fundus examination, and CS. Differences in corrected visual acuity and contrast sensitivity between the 2 groups were analyzed with two independent samples t-test analysis, while correlation between vision and contrast sensitivity in patients was evaluated by using spearman correlation test. Difference in CS was compared between the early and advanced stage of fundus diseases.
 Results: Corrected visual acuity and contrast sensitivity in patient with hypertensive disorders complicating pregnancy were lower than that in the control group (P<0.01). Corrected visual acuity in patients was associated with contrast sensitivity at variously spatial frequencies (P<0.01), showing the most correlation in contrast sensitivity at 6 of spatial frequency (r=0.87). Compared with the early stage, the CS in the advanced patients with fundus diseases was decreased (P<0.01).
 Conclusion: The visual acuity and contrast sensitivity in patient with hypertensive disorders complicating pregnancy are reduced. The CS (6.0 c/d) has the largest correlation with corrected visual acuity. Comparing with the visual acuity, contrast sensitivity can be more comprehensive in evaluation of retinal function damage in patients with hypertensive disorders complicating pregnancy.

The effects of the balance changes of pigment epithelium growth factor (PEDF) and vascular endothelial growth factor (VEGF) in whole-body and retinal tissue on rats with oxygen-induced retinopathy were investigated. Forty-eight neonatal SD rats at the age of 7 days were randomly divided into 4 groups. The neonatal rats in experimental groups were exposed to 75% to 80% oxygen for 5 days and then to normal air, and those in control groups were kept feeding in normal air. At the age of 17 and 22 days, all the neonatal rats received retina angiography with FITC-dextran and the pathological changes of retinal vessels and perfusion were observed. HE staining of the tissue section and the number counting of endothelial cells extending beyond the inner limiting membrane were performed to evaluate the endothelial proliferation. Immunohistochemistry was applied to detect the expression of PEDF and VEGF in retinal tissue, and ELISA to detect their expression in serum. A hypoxic-ischemic proliferation of retina and more endothelial cells extending beyond the inner limiting membrane were found in the neonatal rats in both experimental groups of 17-day old and 22-day old as compared with those in control group with the difference being statistically significant (P<0.01). VEGF staining of the rats in the 17-day old experimental group was significantly stronger, with an increasing positive rate, than that of the rats in the 17-day old control group (P<0.01). PEDF staining of the rats of 22 days old was weaker than that of the rats of 17 days old in the experimental groups (P<0.01). There was no significant difference in serum VEGF concentration among all groups (P>0.05). The serum PEDF concentration in the rats of 17 days old in experimental group was decreased significantly as compared with that in the rats of 17 days old in control group (P<0.01), and in experimental groups, the serum PEDF concentration of the rats of 22 days old was increased as compared with that of the rats of 17 days old (P<0.01). In conclusion, the obviously decreased serum PEDF concentration and the abnormal enhanced expression of VEGF density in local retinal tissue broke down the balance of PEDF/VEGF in whole-body or local tissues, which might play an important role in retinal vascular proliferation.

PURPOSE: To report the results of switching treatment to vascular endothelial growth factor (VEGF) Trap-Eye (aflibercept) in neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) refractory to anti-VEGF (ranibizumab and bevacizumab). METHODS: This is a retrospective study involving 32 eyes from 29 patients; 18 were cases of neovascular AMD and 14 were cases of PCV. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) of spectral-domain optical coherence tomography were evaluated. RESULTS: BCVA and CMT improved from 0.58 to 0.55 (p = 0.005) and from 404 to 321 microm (p < 0.001), respectively, after switching to aflibercept. The 14 eyes that received 6 or more aflibercept injections remained stable at 0.81 to 0.81 and 321 to 327 microm (p = 1.0, 0.29), respectively, after 3 aflibercept injections. The 10 eyes that received 3 or more bevacizumab injections after 3 or more aflibercept injections worsened, from 0.44 to 0.47 and from 332 to 346 microm (p = 0.06, 0.05), respectively. The results showed similar improvement of BCVA and CMT in neovascular AMD and PCV. CONCLUSIONS: Aflibercept seems to be effective for improvement and maintenance of BCVA and CMT for neovascular AMD and PCV refractory to anti-VEGF. Switching from aflibercept back to bevacizumab treatment may not be a proper strategy.

Cosmetic facial filler-related ophthalmic artery occlusion is rare but is a devastating complication, while the exact pathophysiology is still elusive. Cerebral angiography provides more detailed information on blood flow of ophthalmic artery as well as surrounding orbital area which cannot be covered by fundus fluorescein angiography. This study aimed to evaluate cerebral angiographic features of cosmetic facial filler-related ophthalmic artery occlusion patients. We retrospectively reviewed cerebral angiography of 7 patients (4 hyaluronic acid [HA] and 3 autologous fat-injected cases) showing ophthalmic artery and its branches occlusion after cosmetic facial filler injections, and underwent intra-arterial thrombolysis. On selective ophthalmic artery angiograms, all fat-injected patients showed a large filling defect on the proximal ophthalmic artery, whereas the HA-injected patients showed occlusion of the distal branches of the ophthalmic artery. Three HA-injected patients revealed diminished distal runoff of the internal maxillary and facial arteries, which clinically corresponded with skin necrosis. However, all fat-injected patients and one HA-injected patient who were immediately treated with subcutaneous hyaluronidase injection showed preserved distal runoff of the internal maxillary and facial arteries and mild skin problems. The size difference between injected materials seems to be associated with different angiographic findings. Autologous fat is more prone to obstruct proximal part of ophthalmic artery, whereas HA obstructs distal branches. In addition, hydrophilic and volume-expansion property of HA might exacerbate blood flow on injected area, which is also related to skin necrosis. Intra-arterial thrombolysis has a limited role in reconstituting blood flow or regaining vision in cosmetic facial filler-associated ophthalmic artery occlusions.

OBJECTIVETo study the clinical characteristics and diagnostic methods of rare autosomal recessive inherited Bardet-Biedl syndrome in patients presented with renal abnormalities.

METHODComprehensive analyses were performed on data of 4 confirmed Bardet-Biedl syndrome cases seen at nephrology department of Beijing Children Hospital affiliated to Capital Medical University, including clinical features, laboratory examination and diagnostic criteria.

RESULT(1) Four cases were confirmed to meet Bardet-Biedl syndrome diagnostic criteria (male: female = 1: 1): first diagnosis age was 10 y, 9 y 8 m, 10 y 10 m, 8 y 2 m. (2) Cases 1, 2, and 3 had a history of polyuria and polydipsia, cases 4 began with edema and oliguria. (3) All had slight change in urine routine test. Case 3 and Case 4 were presented with small to medium amount of proteinuria. None had microscopic hematuria. (4) All had different degree of renal injury, Case 1 and 3 were at the third phase of chronic kidney disease (CKD), Case 4 was at the fourth phase of CKD, Case 4 was at the fifth phase of CKD and needed dialysis. (5) All cases had obvious abnormalities of urinary tract ultrasound, 3 of them had chronic diffuse lesions with cyst formation of both kidneys. The rest one had dysplasia of right kidney and fused kidney. (6) All cases were presented with vision loss with 100% of electroretinogram abnormalities and 50% of fundus examination abnormalities. (7) Three cases were presented with obesity. (8) Multiple organs were involved in all cases, including electrocardiographic abnormality and/or thickening of the left ventricular wall (4/4) , polydactyly (2/4) , small penis and testicles (2/4) and short stature (2/4) .

CONCLUSIONClinical manifestations of Bardet-Biedl syndrome (BBS) conceals, routine urine test changes slightly, abnormalities of renal structure and (or) tubular interstitial function is a typical manifestation of children with BBS. Urinary tract ultrasound screening may show diffuse lesions with double kidney with cyst formation or structural abnormalities. Clinical manifestation accompany with retinal degeneration, obesity, myocardial involvement, polydactyly, and hypogonadism.

BACKGROUNDIt is very common for professional divers to have damage on the retinas. Severe retinal lesions can profoundly affect athletes' training efficacy and their daily lives. At present, it is not clear if there is effective preventive action. Thus, in our study, we continuously tracked the ocular changes in athletes and closely monitored the risk factors associated with retinal detachment. Also, we analyzed possible interventions, their associated factors, and efficacies for timely preventions to protect the retina from damage in professional divers.

METHODSBetween 2009 and 2012, a total of 39 professional divers enrolled in follow-up management. The conducted examinations included ocular examination, record screening on retinal lesion, monitoring best-corrected visual acuity, and checking intraocular pressure (IOP) and the scope of retinal lesion. The management included optimizing training methods, taking customized follow-up based on different retinal lesions, laser treatments for definite cases of retinal tear, retinal degeneration caused by retinal layer thinning or vitreous traction, and observing the changes in the scope of retinopathy.

RESULTSEvery year, the percentage of divers who have various degrees of retinal lesions is between 43.3% and 56.2%. During the 4 years, there were no statistically significant differences in divers' best-corrected visual acuity and retinal lesions. There were also no statistically significant differences between male and female athletes. However, there were statistically significant differences in IOP during these years. Moreover there were statistically significant differences in IOP and the scope of retinal lesions between platform divers and springboard divers.

CONCLUSIONSOur management of retinal lesions could be effective to prevent severe retinopathy in professional divers. At the same time, platform divers are more likely to have retinal lesions than springboard divers.
