Forty-three patients were diagnosed clinically and radiologically with circumscribed choroidal hemagiomain Beijing Tongren Hospital from February 2010 to August 2018. All patients had exudative retinal detachment and were treated by a domestic radioactive applicator. The size of the tumor (maximum base diameter, maximum height) was recorded by color doppler ultrasound imaging (CDI). Changes insubretinal fluid were observed by indirect ophthalmoscopy and optical coherence tomography (OCT). The changes invisual acuity, intraocular pressure, tumor size and subretinal fluid were compared before and after surgery and the occurrence rates of complications were noted. Data were compared by a paired t-test and Wilcoxon rank sum test. \u0000 \u0000 \u0000Results: \u0000There was a statistically significant difference in visual acuity between the most recent follow-up (2.03±1.45) and pre-operation (2.14±1.36) (Z=-2.348, P=0.019), and no significant difference in intraocular pressure between the most recent follow-up (13.6±6.0 mmHg) and pre-operation (12.5±4.2 mmHg) (Z=-1.419, P=0.3). Tumor size had regressed compared to pre-operative measurements inmaximum basal diameter: The most recent follow-up was 10.3±2.5 mm, pre-operation was 12.3±3.2 mm (t=8.862, P<0.001); maximum height: the most recent follow-up was 2.6±1.3 mm, pre-operation was 4.8±1.4 mm (t=10.387, P<0.001).

Fifteen patients (15 eyes) with high intraocular pressure (IOP) in the early stage after LDPK in the Eye Hospital of Shandong Province were selectedfrom January to June 2017. Postoperative anterior segment SS-OCT was used to record the adhesion and extent of peripheral anterior synechia. Treatment plans were then developed for the patients.

The patients were treated with minimally invasive vitrectomy combined with complete local exfoliation. Systemic metastasis and local scleral and optic nerve invasion were excluded. Mean basal diameter of the tumor was 11.2±4.2 mm. Average height diameter was 9.2±1.1 mm. Tumors were located at the posterior pole and at the equator in 11 cases. Minimally invasive vitrectomy was adopted in combination with intraventricular resection, then the tumors were removed completely. Two of the tumors were large enough to reach the anterior equatorial ciliary body. Minimally invasive vitrectomy was adopted in combination with tumor dissection from the scleral flap.

The replacement was performed because of abnormal vaults of the initial lens implantations, either less than 250 μm or more than 750 μm. Seventy patients (70 eyes) were randomly chosen as the control group from those who underwent ICL implantation during the same period and had normal vaults (250 to 750 μm). Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, intraocular pressure (IOP), corneal endothelial cell density (ECD), and lens thickness (LT) were measured before surgery. The posterior chamber angle, height of the ciliary processes (T value), sulcus-to-sulcus (STS) horizontal distance, STS vertical distance, and anterior chamber depth (ACD) were measured by an ultrasound biomicroscope (UBM). All patients were followed more than 6 months. UCVA, manifest refraction, BCVA, IOP, ECD, and vault height were measured. Data were analyzed using a t-test and multiple linear regression. \u0000 \u0000 \u0000Results: \u0000There were significant differences between the high vault group and the low vault group for posterior chamber angle and ICL size and ACD (all P<0.001). There were significant differences between the high vault group and normal vault group for ICL size and posterior chamber angle. Posterior chamber angle, ICL size, STS horizontal distance, T value, ACD, and LT were statistically significant factors for the abnormal vault (adjusted, R2=0.608, F=5.84, P<0.001). Eight eyes had a vault less than 250 μm after implantable collamer lens replacement in the low vault group. Whereas the vault was normal after ICL replacement in all eyes of the high vault group. There were no serious complications such as anterior subcapsular cataract, high intraocular pressure, or corneal endothelial decompensation during the observation period. \u0000 \u0000 \u0000Conclusions: \u0000Multiple ciliary sulcus factors affect vault after ICL implantation. T value, posterior chamber angle, STS horizontal distance, ACD, ICL size, and LT may be related to an abnormal vault. For cases where abnormal vault may occur, the ICL size can be determined in conjunction with the posterior angle to help achieve a proper vault. \u0000 \u0000 \u0000Key words: \u0000vault; posterior chamber angle; height of ciliary processes; lens thickness","PeriodicalId":10142,"journal":{"name":"Chinese Journal of Optometry & Ophthalmology","volume":"75 1","pages":"534-539"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80658068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-nine patients (98 eyes) who had moderate to severe MGD were recruited in the Second Affiliated Hospital, Fujian Medical University, from April 2016 to January 2017. All patients underwent comprehensive ocular surface examination and slit lamp examination and were divided into two groups: 26 patients in the observation group and 23 patients in the control group. The observation group was given artificial tears and oral azithromycin 500 mg once daily for 3 days, then stopped for 7 days. There were 10 days in a treatment cycle with a total of three cycles for the treatment.The control group received only artificial tear treatment. All patients underwent modified meibomian gland compression during the first visit and for each follow-up, all of which were combined with eyelid hot compress and blepharospasm cleaning. Then an ocular check-up was performed, including the following aspects: Ocular surface disease index (OSDI), noninvasive first break-up time (NIF-BUT), noninvasive average break-up time (NIAvg-BUT), tear meniscus height (TMH), R-scan, loss rate of the meibomian gland, assessment of meibomian gland orifices, meibum quality score, meibum expression score, fluorescein stain test (FL), and Schirmer Ⅰ test (SⅠT) between pre-therapy and post-treatment. Data were analyzed by an independent samples t test, Mann-Whitney U test, paired t test and Wilcoxon paired rank sum test. \u0000 \u0000 \u0000Results: \u0000After treatment, the assessment of meibomian gland orifices (Z=-3.093), meibum quality score (Z=-2.501), meibum expression score (Z=-3.175) as well as FL (Z=-2.602) of the control group were improved compared with those before treatment, with statistically significant differences (P<0.05). However, there were no statistically significant differences in other indexes in the control group. After treatment, the OSDI (t=6.174), loss rate of the meibomian gland (t=2.402), assessment of meibomian gland orifices (Z=-5.192), meibum quality score (Z=-5.073), meibum expression score (Z=-4.807), and FL (Z=-3.587) of the observation group were improved compared with those before treatment, with statistically significant differences (P<0.05). There were no statistically significant differences in other indexes in the observation group. Statistically significant differences were observed in OSDI (t=-3.778), NIAvg-BUT (Z=-2.043), loss rate of the meibomian gland (t=-2.123), assessment of meibomian gland orifices (Z=-6.318), meibum quality score (Z=-5.852), meibum expression score (Z=-3.951) and SⅠT (Z=-2.462) between the two groups after treatment (P<0.05) and the observation group improved more obviously, but no statistically significant differences in other indexes after treatment. \u0000 \u0000 \u0000Conclusions: \u0000Oral azithromycin can be used to t","PeriodicalId":10142,"journal":{"name":"Chinese Journal of Optometry & Ophthalmology","volume":"79 1","pages":"540-548"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90854463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
