ABSTRACT
AIM: To investigate the efficacy of orbicularis oculi muscle resection combined with orbicularis oculi muscle shortening and lower eyelid retractor reduction in the treatment of elderly lower eyelid entropion.METHODS:A retrospective study was conducted among 97 elderly patients(175 eyes)with lower eyelid entropion who admitted to the hospital from June 2019 to June 2021. According to the treatment method, the patients were divided into control group(47 patients of 82 eyes treated with orbicularis oculi muscle resection)and combination group(50 patients of 93 eyes treated with orbicularis oculi muscle resection combined with orbicularis oculi muscle shortening and lower eyelid retractor reduction). The two groups were compared in terms of short-term curative effect, perioperative indexes, scores of symptoms and signs before and after surgery, width of palpebral fissure before and after surgery, direction of eyelashes, exposure rate of lacrimal caruncle, complications, and patient satisfaction.RESULTS: The total response rate in the combination group was significantly higher than that in the control group(95% vs 80%, P=0.004). The intraoperative blood loss, operation time and hospital stay of the combination group were significantly more/longer than those of the control group(P<0.001). The scores of symptoms and signs such as lacrimation, foreign body sensation, photophobia and irritation in the combination group after the surgery were significantly lower than those in the control group(all P<0.001). After surgery, the width of palpebral fissure, direction of eyelashes and exposure rate of lacrimal caruncle in the combination group were higher than those in the control group(P<0.001). The incidence of postoperative complications in the combination group was lower than that in the control group(8% vs 18%, P=0.032). The patient satisfaction scores of comfort level, trichiasis correction, scar appearance, eyes symmetry and appearance in the combination group were higher than those in the control group(all P<0.001).CONCLUSION: Orbicularis oculi muscle resection combined with orbicularis oculi muscle shortening and lower eyelid retractor reduction is effective and safe in the treatment of elderly lower eyelid entropion, which can meet the requirements of the patients.
ABSTRACT
AIM: To investigate the incidence of trachoma in children aged 1 to 9y in Hainan Province and determine high-risk trachoma endemic and non-endemic areas in Hainan, and thus provide evidence for developing trachoma control and prevention therapy.METHODS:The areas of investigation were chosen on the basis of past literatures, expert interviews and survey on the spot.In 2013, Hainan Provincial Office of Blindness Prevention carried out the survey in 7 counties including Dongfang City, Wuzhishan City, Ledong County, Baisha County, Baoting County, Lingao County and Changjiang County.In these districts, 356 pupils including 192 boys and 164 girls were examined, their age ranging from 1 to 9 and their average age being 7 years old.The targeted students received the trachoma rapid assessment by the adoption of simplified trachoma classification system which was recommended by the World Health Organization.RESULTS: No case of active trachoma was found among the 356 students.CONCLUSION:The prevalence rate of trachoma in children under 9 years is less than 5% in Hainan Province.Active trachoma is not a public health issue in Hainan Province.
ABSTRACT
AIM: To observe the effect of intravenous methylprednisolone combined with peri - orbital injection of triamcinolone acetonide for diffuse - type orbital inflammatory pseudotumor. METHODS: Diffuse - type orbital inflammatory pseudotumor in 15 cases ( 19 eyes ) were treated. Intravenous implosive methylprednisolone therapy (0. 5g/ d) was used in the first 3d, and 0. 5g once a week in the following 3wk, ended by 0. 25g once a week in the last 6wk, which meant the total dose was 4. 5g and the whole course lasted for 10wk. At the same time, peri - orbital injection of triamcinolone acetonide ( 40mg ) was performed once in every 3wk, totally 2-4 times. RESULTS: Eight eyes from 7 cases were completely cured, 11 eyes from 8 cases were partly cured. No recurrence and severe complications were observed in the treatment duration. CONCLUSION: Intravenous methylprednisolone combined with peri - orbital injection of triamcinolone acetonide is effective, safe and feasible in treatment of diffuse type orbital pseudotumor with less complications.
ABSTRACT
?AlM: To investigate repeatability and accuracy of a latest Keratograph for evaluating the tear film stability and to compare its measurements with that of traditional examination methods. ?METHODS: The results of noninvasive tear film break-up time ( Nl-BUT ) including the first tear film break-up time ( BUT-f ) and the average tear film break-up time ( BUT - ave ) were measured by Keratograph. The repeatability of the measurements was evaluated by coefficient of variation ( CV ) and intraclass correlation coefficient ( lCC) . Wilcoxon Signed-Rank test was used to compare Nl-BUT with fluorescein tear film break-up time ( FBUT) to confirm the correlation between Nl-BUT and FBUT, Schirmer l test values. Bland-Altman analysis was used to evaluate consistency. ?RESULTS: The study recruited 48 subjects ( 48 eyes ) (mean age 38. 7±15. 2 years). The CV and lCC of BUT-f were respectively 12. 6% and 0. 95, those of BUT-ave were 9. 8% and 0. 96. The value of BUT-f was lower than that of FBUT. The difference had statistical significance ( 6. 16±2. 46s vs 7. 46±1. 92s, P ?CONCLUSlON: Keratograph can provide Nl-BUT data that has a better repeatability and reliability, which has great application prospects in diagnosis and treatment of dry eye and refractive corneal surgery.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the epidemiological and etiologic characteristics of ocular fungal infection in Haikou.</p><p><b>METHODS</b>The samples of corneal, conjunctivae, anterior chambers, lacrimal sacs were taken from the outpatients and inpatients in the Department of Ophthalmology for fungal culture. The positivity rates of fungal culture were statistically analyzed to describe the seasonal and genus distribution of the fungal infections.</p><p><b>RESULTS</b>A total of 683 patients were involved in this study, and the total positivity rate of fungal culture was 27.96%. The positivity rate was 33.42% in male patients and 21.52% in female patients (P<0.01). The positivity rates were 31.42%, 11.32%, 10.81%, 21.28% and 29.17% in the cornea, conjunctivae, anterior chambers, lacrimal sacs and other locations (P<0.01), and were 34.88%, 22.58%, 11.76%, 4.11%, 21.43% and 13.33% in farmers, workers, teachers, government officers, students and personnel of other occupations (Chi2=39.550, P=0.001), respectively. In terms of age, the rate was 32.30% in 21-40 years group, 31.72% in 41-60 years group, 17.12% in over 60 years group and 26.61% in below 20 years group, showing significant differences (P<0.01). The rates were higher in August, September, October, December, November, all above 30%, but lower in March. Nine genera were identified, including Candida (49.21%), Aspergillus (19.37%), Fusarium (9.42%), mucor (5.76%), Actinomyces (5.24%), Penicillium (3.66%), Saccharomyces (2.62%), non-spore group (1.57%), Alternaria (1.57%), and other genera (1.57%). Among the 94 strains of Candida, 63 (67.02%) belonged to Candida albicans and 14 to Candida tropicalis (14.89%).</p><p><b>CONCLUSION</b>Ocular fungal infection occurs more often in male patients and in the cornea. The common pathogen of ocular fungal infection is Candida, which is different from the etiological characteristics in other areas possibly in association with the tropical climate.</p>
