Background It is determined that the patients with thyroid-associated ophthalmopathy (TAO) often occur dry-eye related symptoms due to increasing tear evaporation caused by exophthalmos.However,more than half of thyroid dysfunction patients without TAO appear ocular surface inflammation.It is very important for us to understand the association of thyroid dysfunction patients without TAO with ocular damage.Objective This study was to observe the ocular surface changes in thyroid dysfunction patients without TAO.Methods A prospective cohort study was performed.Thirty-one patients who were initially diagnosed as thyroid dysfunction without TAO were included in the Second Hospital of Tianjin Medical University from January 2015 to May 2016 as the thyroid dysfunction group,and 16 helthy subjects were simutenniously selected as the control group under the informed consent of all the individuals.The peripheral blood was collected to detect the thyroid function-related indexes.Then the patients with thyroid dysfunction were divided into thyroid stimulating hormone (TSH) reduced group (18 patients) versus TSH elevated group (13 patients) and thyrotrophin receptor antibody (TRAb)+ group (20 patients) versus TRAb-group (11 patients).Exophthalmos degree,Schirmer I test (S I t),tear film break-up time (BUT),fluorescent integral,ocular surface disease index (OSDI) and corneal inflammation index were examined and intergrouply compared.The correlations of thyroid function indexes with ocular surface examination results were analyzed.Results There were no significant differences in exophthalmos degree and S I t values between thyroid dysfunction group and control group (t =0.037,P =0.971;t =0.815,P =0.419).The BUT values were (7.74 ± 1.45) seconds and (10.56± 1.40) seconds,fluorescent integral scores were 5.00 (1.50) and 2.50 (2.38),OSDI scores were 45.58 ± 9.23 and 19.47 ± 6.25,and corneal inflammation index scores were 0.11 (0.22) and 0.00 (0.06) in the thyroid dysfunction group and the control group,respectively,showing significant differences between the two groups (all at P＜0.01).There were not significant differences in exophthalmos degree,S I t,BUT and corneal inflammation index scores between the TSH elevated group and TSH reduced group (t =0.473,P =0.640;t =0.650,P=0.521;t=1.634,P=0.l13;Z=0.270,P=0.787).The fluorescent integral scores were 4.00 (2.00) and 5.00 (1.00),and OSDI scores were 40.08±9.91 and 47.11±9.75 in the TSH elevated group and TSH reduced group,repectively,with statistically significant differences between these two groups (all at P＜0.01).The exophthalmos degrees,S I t,BUT and corneal inflammation index scores were not considerably different between TRAb-group and TRAb+ group (all at P＞0.05);and significant differences were seen in fluorescent integral scores (4.00[1.50] vs.5.50 [1.50]) and OSDI scores ([39.18±6.25] vs.[46.78±8.76]).Corneal inflammation index scores were positive correlated with serum TSH (R2 =0.520,P =0.000),and fluorescent integral scores,OSDI scores and corneal inflammation index scores were positive correlated with serum TRAb (R2 =0.587,P =0.000;R2 =0.329,P =0.024;R2 =0.400,P=0.005).Conclusions Thyroid dysfunction patients without TAO have ocular surface dysfunction,which probably is associated with abnormal serum TSH and TRAb.

Objective To observe the clinical features and prognosis of endogenous bacterial endophthalmitis (EBE).Methods Ten eyes of 10 patients diagnosed with unilateral EBE were retrospectively reviewed,including 7 males and 3 females.The mean age was 57.6± 10.8 years old.Eight patients were with diabetes and 7 of them were diagnosed over 5 years.There were 3 patients with hepatocirrhosis,1 patient with hypertension,and 1 patient with coronary disease.Nine cases had infectious diseases,including liver abscess (7 cases),pulmonary infection (3 cases),erysipelas (1 case) and perianal abscess (1 case).Seven cases had fever history.Culture and drug sensitive tests for aerobic bacteria,anaerobic bacteria and fungal were performed for 9 eyes using vitreous samples from the procedures of vitrectomy and/or intravitreal injection.All patients were treated with broad-spectrum antibiotics and adjusted for drug use according to microbiological culture and drug sensitivity test results.After the diagnosis was established,vitrectomy combined with lens removal was performed in 5 hours (3 eyes) and 24 hours (5 eyes);Vitreous tamponade of C3F8 (1 eye) and silicone oil (7 eyes) was used;At the end of the operation,0.1 ml vancomycin (1 mg) and 0.1 ml ceftazidime (1 mg) were injected into the vitreous cavity.One eye received intravitreal injection of 0.1 ml vancomycin (1 mg) and 0.1 ml ceftazidime (mg),one eye received evisceration.During the follow up period from 6 to 24 months,visual function,slit lamp and fundus examinations were performed at each office visit.Results All patients complained of blurred vision and 5 patients had ocular pain.The visual acuity was no light perception (3 eyes),light perception (5 eyes);hand motion (1 eye) and 0.1 (1 eye).Corneal edema was found in all 10 eyes;hypopyon in 8 eyes;diffuse vitreous opacity in 10 eyes,including 3 eyes with retinal detachment.For 8 eyes treated by vitrectomy and intravitreal injection,1 eye was eviscerated due to uncontrolled inflammation.The eye treated with intravitreal injection was enucleated for its uncontrolled inflammation.For 9 eyes received vitreous culture and drug testing,8 eyes (88.9％) had positive results,including 5 eyes with Klebsiellar pneumonia,and 1 eye with Staphylococcus aureus,or Streptococcus agalactiae or Enterococcus faecalis respectively.At last office visit,2 eyes were with no light perception;4 eyes were with hand motion;and 1 eye with visual acuity of 0.1.Conclusions Most of the patients with endogenous bacterial endophthalmitis have systemic predisposing factors.Klebsiella pneumoniae is the leading cause of ocular EBE.Vitrectomy combined with intravitreal injection of antibiotics showed efficacy in treating EBE.

Objective: To observe the ocular surface function changes of dry eye patients with seborrheic dermatitis and discuss the significance of seborrheic dermatitis in ocular surface damage. Methods: A cohort study was performed.Forty-nine patients (49 eyes) who were initial diagnosed with dry eye enrolled in General Hospital of Tianjin Medical University from October 2015 to March 2016 were divided into 2 groups, including 21 patients with seborrheic dermatitis and 28 patients without seborrheic dermatitis.Gender, age, meibomian gland dysfunction (MGD), eyelid margin scores, eyelid secretions scores, meibomian gland imaging scores, conjunctival congestion scores, ocular surface disease index (OSDI), Schirmer Ⅰtest (SⅠt), break-up time of tear film (BUT), fluorescent integral score were examined and compared.The study was followed the Declaration of Helsinki and was approved by General Hospital of Tianjin Medical University (No.IRB2015-YX-069). Written informed consent was obtained from all subjects before entering the study. Results: There were not significant differences in gender and ages (χ²=1.536, P=0.215; t=0.642, P=0.524). The rate of MGD in seborrheic dermatitis group was 57.15%, which was significantly higher than that in the non-seborheic dermatitis group (25.00%), with significan difference between the two groups (χ²=5.222, P=0.022). There were significant differences in eyelid margin scores, eyelid secretions scores, meibomian gland imaging scores, fluorescent integral scores between the two groups (Z=2.105, 3.303, 3.368, 3.036, all at P<0.05). The OSDI in the seborheic dermatitis group was 26.43±8.05, which was significantly larger than that in the non-seborheic dermatitis group (16.75±5.74); the BUT in the seborheic dermatitis group was (6.14±1.98)s, which was significantly shorter than that in the non-seborheic (8.75±1.38)s (t=4.918, 5.434; both at P<0.05). Conclusions Seborrheic dermatitis may aggravate ocular surface dysfunction in dry eye patients.
