ABSTRACT
Objective To observe the fundus lesions in the unilateral rhegmatogenous retinal detachment (RRD) eyes and contralateral eyes in non-traumatic emmetropia patients,and explore the risks of lateral eyes.Methods This is a retrospective case analysis.A total of 426 patients of unilateral RRD diagnosed by clinical examination were enrolled in this study.There were 273 males and 74 females.The average age of onset was 54.7 years.81.46％ of them (347 patients) were 51-70 years old.The average detachment time was 2.12 months.They were divided into two groups,equal or lesser than 50 years old group and more than 50 years old group.A total of 100 patients (200 eyes) with ocular surface disorders were randomly selected as control.The lattice-like degeneration,cystic degeneration and dry retinal holes were treated with prophylactic laser photocoagulation.Follow-up period was 6 to 24 months.The age,gender,proliferative vitreous retinopathy (PVR) grading,best corrected visual acuity (BCVA),distribution and quantity of retinal holes,and posterior vitreous detachment (PVD) were retrospectively analyzed.The incidence of PVD among different age groups was compared with Chi square.Results Among 426 RRD eyes,there were 239 eyes (56.10％) with PVD.Among them,there were 30 eyes with age equal or lesser than 50 years old (12.55％) and 209 eyes with age more than 50 years old (84.75％).There were 187 eyes (43.90％) without PVD,which including 38 eyes with age equal or lesser than 50 years old (20.32％) and 149 eyes with age more than 50 years old (79.68％).The incidence of PVD among different age groups was statistically significant (x2=4.72,P＜ 0.05).There were 10,254,40 and 5 eyes in class A,B,C and D of PVR,respectively;117 eyes without PVR.The retinal hole was located in superior temporal,inferior temporal,superior nasal,inferior nasal and macular in 305,91,22,4 and 4 eyes,respectively.The number of holes was 1,2,and more than 3 in 297,89 and 40 eyes,respectively.The retinal detachment range of 1,2,3 quadrants and total dissociation were 92,230,71,33 eyes,respectively.The fundus lesion was found in 47 eyes (11.03％) in the lateral eyes.There were 20 RRD eyes in class B of PVR,and 27 RRD eyes in class C of PVR.Retinal degenerated area was found.Among them,the degeneration of 41 eyes was located in the temporal retina,45 eyes involved in a quadrant.There were 16 eyes with peripheral retinal dry holes;the holes diameter was less than 1,1-2,greater than 2 optic-discs in 6,11 and 5 retinal holes.At the end of the follow-up,there were 47 eyes with almost normal visual field,16 eyes with decreased visual acuity,noeyes with retinal detachment.In the control group,4 patients (5 eyes,2.50％) had fundus lesions.Conclusion The unilateral RRD in non-traumatic emmetropia mostly occurs in elderly patients;11.03％ of patients had fundus lesions in the contralateral eyes,higher than the general population.
ABSTRACT
Objective To discuss the relationship between diabetic macular edema(DME) and visual field defects and evaluatethe therapeutic effect of micro-pulse laser.Methods A total of 117 patients (149 eyes) with diabetic retinopathy(DR) were enrolled in this study and divided into two groups according to early treatment diabetic retinopathy study(ETDRS) DME diagnostic criteria:DME group(n=50,70 eyes) and N-DME group(n=67,79 eyes).Healthy subjects(n=40,80 eyes)were selected as NC group in thisstudy.The clinical data and biochemical index were collectedand visual fields were examined in all the subjects.Then the DME group was further divided into two subgroups:micro-pulse laser subgroup(35 eyes) and conventional laser subgroup(35 eyes).The vision recovery after treatment was evaluated on different time points.Results Diabetes duration,FPG,HbA1c and HOMA-IR were significantly higher in DME group than in N-DME group (P0.05).Multiple logistic regression analysis showed that DM duration,FPG,HbA1c and HOMA-IR were riskfactors for DME(all P<0.01).Conclusion Patients with DME have severe vision loss.Micro-pulse laser therapy is helpful invision recovery,while conventional laser therapy have no obvious effect on it.Longer duration of DM,higher level of FPG,HbA1c,and IR severity may increase the risk of DME.
ABSTRACT
Objective To investigate the clinical effects of high-density micropulse photocoagulation (HD-SDM) combined with intravitreal injection of ranibizumab for diabetic macular edema (DME).Methods Thirty-one patients (31 eyes) with DME were randomly divided into two groups.Group A (15 eyes) received HD-SDM combined with intravitreal injection of ranibizumab.Group B (16 eyes) only received intravitreal injection of ranibizumab.The best corrected visual acuity (BCVA) and central macular thickness (CMT) of the two groups before and after treatment were analyzed,and the annual injection times of the two groups were compared.Results The average annual injection times was 3.67 ± 1.11 in group A,and 9.12 ±2.63 in group B.The difference was significant between the two groups (t =2.05,P ＜ 0.05).There were significant differences in CMT before and after treatment in both groups (all P ＜ 0.05).There was no significant difference in CMT between the two groups(t =1.19,P ＞ 0.05).There were significant differences in BCVA before and after treatment in both groups (all P ＜ 0.05),but there was no significant difference before and after treatment between the two groups(all P ＞ 0.05).Conclusion Both HD-SDM combined with intravitreal injection of ranibizumab and single intravitreal injection of ranlbizumab are effective for DME,but the combining treatment can remarkably decrease the annual injection times and had a good compliance of patients,is a good choice for DME patients.
ABSTRACT
Objective To explore the ability of advanced oxidation protein products (AOPP)in predicting the progression of diabetic retinopathy (DR)in patients with type 2 diabetes mellitus (T2DM). Methods 363 T2DM patients were enrolled in this prospective cohort study. According to the quartile points of baseline AOPP level,patients were divided into four groups (Q1,Q2,Q3 and Q4 ). The progression rate of DR was calculated according to the changes of non-mydriatic fundus photography after a 5-year follow-up. Results With the increase of baseline AOPP level,the rate of progression of DR increased (19.51% vs 28.42% vs 37.36% vs 47.37%,P <0.01). Logistic regression analysis showed that baseline level of AOPP was an independent risk factor for the progression of DR (OR=1.833,95%CI:1.573~1.982,P<0.05).Area under the curve of AOPP in predicting DR is 0.883 (95% CI:0.842~0.924)with the sensitivity 86.1% and specificity 91.9%. Conclusion AOPP may be one of the biomarkers for the prediction of type 2 diabetic retinopathy progression.
ABSTRACT
To explore the treatment method and preventive measures on epidemic keratoconjunctivitis. 108 patients with epidemic keratoconjunctivitis who received treatment in our hospital from January, 2015 to September, 2015.were selected. These patients were treated with interferon eye drops, Ganciclovir ophthalmic gel, and alternating eye treatment of tobramycin-dexamethasone eye drops and diclofenac sodium eye drops. Meanwhile, health education was also performed among patients, so as to promote the recovery of the disease as soon as possible and to prevent the spread of the disease Among the 108 patients, there were 101 patients recovered. 7 patients had cornea remained sub epithelial round hoary haze, including 2 patients with evident cornea remained sub epithelial round hoary haze due to the occurrence of glucocorticoid-induced intraocular pressure and the tobramycin and dexamethasone eye drops were suspend. The clinical cure rate was 91.79%. There was no pathophoresis to health patients among the 108 patients. Active treatment of epidemic keratoconjunctivitis, combined with health education and publicity could increase the clinical cure rate and control the transmit of the disease spread
