Refractory macular edema is a common manifestation of a variety of eye diseases, and it is one of the important causes of impaired vision in patients. The pathogenesis of macular edema is unclear, mainly related to the destruction of the retinal barrier, the expression of inflammatory factors, and the increase of vascular endothelial growth factor. Refractory macular edema is a recurrent disease, which has no response to drugs, seriously affecting vision. The main current clinical treatment is intravitreal anti-vascular endothelial growth factor injection. But for some of the patients who are insensitive to this treatment, intravitreal glucocorticoids injection is performed, but glucocorticoids have the risk of causing elevated intraocular pressure, so the safety of intravitreal glucocorticoids implant needs further study. Appropriate application of retinal laser photocoagulation can reduce the incidence of refractory macular edema, and help resolving the macular edema in some patients. Vitrectomy combined with internal limiting membrane peeling can relieve the tangential stress on the surface of macular and help to eliminate edema, but the surgical mechanical damage to the retina may not be beneficial to vision improvement. On the clinic, patients receive customize individualized treatment according to the pathogenesis, and if necessary, choose combined treatment to eliminate edema as soon as possible to avoid irreversible visual impairment. Key words: Edema, macular, refractory; Anti-vascular endothelial growth factor; Vitrectomy

Objective To evaluate the efficacy of microcatheter-assisted trabeculotomy for the treatment of juvenile open angle glaucoma(JOAG). Methods Retrospective case cohort series study. Clinical datas of 20 eyes of 15 cases with JOAG treated with microcatheter-assisted trabeculotomy from Apr.2017 to May 2018 at Eye Hospital Affiliated to Chengdu University of T. C.M. were collected and analysed. Results The pre-operative IOP was (33.55±10.73) mmHg (1 mmHg=0.133 kPa). The post-operative IOP decreased to(15.55±3.88)mmHg at last follow-up, and the difference was statistically significant between before and after surgery (t=9.320, P=0.000). The kinds of anti-glaucoma drugs used before surgery were 3.25±0.55 and at the last follow-up decreased to 0.80±1.32 (Z=-3.750, P=0.001). The full success rate of the last follow-up was 70.00 %(14/20) and conditional success rate was 90.00%(18/20). No severe complication occurred intraoperative and psotoperative.

Objective To observe the efficacy of intravitreal injection of conbercept in the treatment of macular edema secondary to branch retinal vein occlusion. Methods The data of 33 eyes of 33 patients with macular edema secondary to retinal branch vein occlusion (BRVO-ME) from Jan.2018 to Dec.2018 were retrospectively analysed. The followed-up time was 3 months. Results BCVA(logMAR) were improved at 1, 2, and 3 months after injection, and the difference were statistically significant between before and each time after injection(Z=4.948, 4.642, 4.305, P=0.000, 0.000, 0.000). Central macular retinal thickness (CMT) decreased at 1, 2, and 3 months after injection, and the difference were statistically significant(Z=4.315, 4.404, 4.387, P=0.000, 0.000, 0.000).

Objective To evaluate the efficacy of riboflavin-ultraviolet A (UVA) collagen crosslinking (CXL) combined with drugs for the treatment of alkali-induced corneal burns in rabbits. Methods Prospective experimental study.The corneas of left eyes of 40 healthy New Zealand rabbits were established alkali burn model. All rabbits were randomly divided into 4 groups: the model group, drugs treatment group, crosslinking group and combined group, with 10 cases in each group. The model goup received no treatments. The drug goup received drug treatment. Riboflavin-UVA collagen crosslinking was appied in crosslinking group and the combined group received CXL combined with drug treatment. Therapeutic efficacy of each group were compared at 1 and 3 months after operation. Results The corneal epithelial healing time in the model group, drug group, cross-linking group and combined group were (32.9±5.8 ), (12.8±2.3), (25.9±3.2 ) and (10.7±2.5 )days, respectively. The difference were statistically significant among the four groups (F=67.647, P=0.000) . The corneal turbidity score of combined group was the lowest among the 4 groups, followed by the drug group, and the score of model group was the heaviest (F=6.446, P=0.001). The number of inflammatory cells were (162.6±33.3), (46.0±21.3 ), (87.9±7.5)and (8.3±6.5)cells respectively under single confocal microscopy field of vision ( 400 μm×400 μm). The difference among the 4 groups was statistically significant (χ2=36.040, P=0.000). The corneal collagen fibers with pathological examination in the combined group were the thickest and densely arranged, followed by crosslinking group. Conclusion The efficacy of drug combined with cross-linking for the treatment of corneal alkali burn in rabbits is better than that of simple drug therapy or simple corneal collagen cross-linking.

The drug goup received drug treatment. Riboflavin-UVA collagen crosslinking was appied in crosslinking group and the combined group received CXL combined with drug treatment. Therapeutic efficacy of each group were compared at 1 and 3 months after operation. \u0000 \u0000 \u0000Results \u0000The corneal epithelial healing time in the model group, drug group, cross-linking group and combined group were (32.9±5.8 ), (12.8±2.3), (25.9±3.2 ) and (10.7±2.5 )days, respectively. The difference were statistically significant among the four groups (F=67.647, P=0.000) . The corneal turbidity score of combined group was the lowest among the 4 groups, followed by the drug group, and the score of model group was the heaviest (F=6.446, P=0.001). The number of inflammatory cells were (162.6±33.3), (46.0±21.3 ), (87.9±7.5)and (8.3±6.5)cells respectively under single confocal microscopy field of vision ( 400 μm×400 μm).

Objective To introduce techniques of femtosecond laser capsulorhexis and intraocular lens modified four-point ciliary sulcus suture fixation combined with standard capsular tension ring for the treatment of severe traumatic lens subluxation. Methods The data of 4 eyes of 4 patients with severe traumatic lens subluxation from May 2018 to Nov. 2018 were collected. All patients received femtosecond laser capsulorhexis and phacoemulsification. Then they received standard capsular tension ring implantation combined with modified four-point ciliary sulcus suture fixation. Results All patients were followed up for 6-12 months. No intra-and postoperative complication happened. Conclusion Femtosecond laser and suspension of intraocular lens for the treatment of severe traumatic subluxation of lens is a safe and easy technique.

Objective To observe the cause of frequent nictitation in children. Methods Total of 178 children aged 3-14 years with frequent nictitation from Jul.2017 to Jun.2018 were collected.All cases received detailed inquiries about medical history and lifestyle. Visual acuity, intraocular pressure, refractive status, schirmer Ⅰ test, tear film break-up time and corneal fluorescein staining test were performed. Results Video Terminal (VDT) syndrome occurred in 98 patients (55.1%). The tear fluid secretion result was lower than 10mm/5min in 3 cases(1.7%). BUT was less than 10 s in 154 cases(86.5%). There were 143 cases of normal vision (80.3%), 84 cases of hyperopia (47.2%) and 45 cases of myopia (25.2%). Corneal fluorescein staining occurred in 43 cases(24.2%), and trichiasis occurred in 20 cases(11.2%). Intraocular pressure was higher than 21 mmHg in 6 cases(3.4%)(1 mmHg=0.133 kPa). Conclusion The frequent nictitation of children are caused by many kinds of reasons. A series of eye discomfort caused by video terminal syndromeis are particularly significant in children. Dry eyes are another major cause of frequent nictitation in children. The main reason for dry eyes in children is unstable tear film, and the shortening of tear film rupture time is the most common (86.5%). Dry eye is also affected by many factors such as lifestyle, environment, eye diseases and drugs. Key words: Nictitation, frequent, children; Syndrome VDT; Asthenopia; Dry eye
