At present, COVID-19 continue to spread in China and are highly contagious. Ocular symptoms are represented by conjunctivitis. When children in the incubation period come to the clinic, it is very easy to cause infection by medical staff and leading to the spread of epidemic. During the epidemic, the principle of non-severe, treatment should be elective. However, when children need to go to the hospital for medical treatment due to the illness, protective measures shall be taken. Coincides with the peak children’s visits during the holidays, in order to do a good job of treatment management and medical staff protection, to prevent the spread of the epidemic and protect the health of medical staff. This paper reviews the main features of COVID-19, how to protect pediatric ophthalmologists and their clinical work of COVID-19 for clinicians’ reference.

Objective To analyze the clinical characteristics of pediatric ocular trauma. Methods A retrospective study. Clinical data of 165 eyes of 164 cases with ocular trauma aged 0-14 years in the Second Affiliated Hospital of Chongqing Medical University from Apr. 2009 to Apr. 2019 were analyzed. All patients were compared according to age, sex, time of injury, population distribution, causes, types of trauma, complications and efficacy of treatment. Results The incidence of pediatric ocular trauma in boys was higher than that in girls and the incidence was higher in rural areas than that in cities. The ocular trauma was more common in children aged 3-8 years. Penetrating injury was the most common type, and traumatic cataract often occurred in ocular trauma. The following types were ocular contusion and ocular adnexal trauma. There were varieties of vulnerant, and the most injury were caused by implements, including knives, sticks, broken bowl, glass, pebble and so on. The visual acuity were improved to different extent after timely treatment. Conclusion The focus of prevention and treatment of pediatric ocular trauma in different age groups are different. Early treatment will improve the prognosis of visual acuity. Key words: Trauma, ocular, pediatric; Complications; Prevention; Treatment

Objective To observe the visual acuity, corneal astigmatism and quality of life of patients with hard nucleus cataract after small incision manual nuclear extraction (non-phacoemulsification). Methods Prospective cohort study.Total of 440 eyes of 440 cases with hard nucleus cataract from Jan.2014 to Jan.2019 in Yuyao Maternal and Child Health Hospital were randomly divided into two groups.There were 198 cases in small incision manual nuclear extraction group (manual group) and 242 cases in phacoemulsification group (phaco group). Follow-up time was 3 months. Results At 1 month after operation, the complication rate in the manual group was lower than that in the phaco group (P=0.028). At 3 months after operation, there was no significant difference in distribution of uncorrected visual acuity between the two groups (P=0.776, 0.712, 0.810). The corneal astigmatism of the manual group was lower than that of the phaco group (P=0.000). There was no significant difference in general health status, far work, ophthalmodynia, social function, social role limitation, independence, or mental health questionnaire score between the two groups (P=0.230, 0.601, 0.259, 0.296, 0.544, 0.492, 0.547). The score of overall vision, near work, color vision and peripheral vision in the manual group were higher than those of the phaco group (P=0.000). Conclusion Small incision manual cataract surgery for the treatment of hard nucleus cataract can not only improve the visual acuity, but also reduce corneal astigmatism and the incidence of complications, and improve the visual related quality of life of patients.

Objective To analyze the clinical characteristics of traumatic glaucoma in children. Methods This is a retrospective study.The data of 67 eyes of 67 cases with secondary glaucoma in 425 children with ocular trauma, aged 1 to 14 years, from Jan. 2014 to Dec. 2018 in First Affiliated Hospital of Zhengzhou University were analysed retrospectively. There were 52 eyes of 52 cases with secondary glaucoma caused by closed ocular trauma in closed ocular trauma group, and 15 eyes of 15 cases with secondary glaucoma caused by open ocular trauma in open ocular trauma group. The clinical characteristics, treatment methods and efficacy of treatment of the two groups were analyzed. The follow-up time was 1 month- 2 years. Results There were 251 cases of closed ocular trauma and 174 cases of open ocular trauma in children. The incidence of secondary glaucoma caused by closed ocular trauma (20.72%, 52/251) was higher than that of open ocular trauma (8.62%, 15/174), and the difference was statistically significant (χ2=11.323, P=0.001). The onset time of secondary glaucoma caused by closed ocular trauma was earlier than that of open ocular trauma. Hyphema (40.38%, 21/52) was the main cause of secondary glaucoma due to closed ocular trauma, and the mixed mechanism was the main cause of secondary glaucoma due to open ocular trauma (73.33%, 11/15). The two groups received conventional medicine first, and 22 cases (42.31%, 22/52) of closed ocular trauma group and 3 cases (20.00%, 3/15) in open ocular trauma group were converted to surgery because of lose control of IOP. The difference in surgery rate was not statistically significant between the two groups(χ2=2.477, P=0.116). At the last follow-up, the mean IOP of closed ocular trauma group was higher than that of open ocular trauma group (t=2.828, P=0.006). There was no statistical significance in BCVA between the two groups at the last follow-up (t=-1.244, P=0.218). Conclusion Secondary glaucoma caused by closed ocular trauma is more common than open ocular trauma. Treatment with medicine is still the first choice, but filtering surgery is an effective way to control secondary glaucoma with closed ocular trauma.

Objective To evaluate the efficacy of 25 G vitrectomy combined with macular massage and negative pressure suction for the treatment of giant idiopathic macular hole. Methods Clinical data of 27 eyes of 27 patients with giant idiopathic macular hole, of which the diameter was 500-800 μm, from Apr.2016 to Dec.2018 in Hanyang Eyegood Ophthalmic Hospital was analyzed retrospectively. Macular massage and negative pressure suction with flute needle were performed after 25 G vitrectomy and peeling of the inner limiting membrane. Results Macular hole closure at 3-5 days postoperatively occurred in 25 eyes(92.6%). Best corrected visual acuity (BCVA, logMAR) at 3-5 days postoperatively were ameliorated from 1.28±0.30 to 1.04±0.37(t=3.860, P=0.032). The postoperative intraocular pressure (IOP) was similar to the preoperative IOP within normal limits(t=2.147, P=0.226). No complication such as iatrogenic injury of macular, bleeding, retinal detachment or secondary glaucoma was recorded in the intra-operative and the follow-up period. Conclusion 25 G vitrectomy combined with macular massage and negative pressure suction contributes to the anatomical repair and visual function recovery of patients with giant idiopathic macular hole.

Objective To observe the efficacy of application of 3D printing technique in repair surgery for orbital blowout fracture. Methods A retrospective study. The clinical data of 13 patients with orbital blowout fracture from Jul.2016 to Dec.2017 in Peking University International Hospital were analyzed. All patients received thin-slice spiral CT scanning. The data were used to three-dimensional reconstruction and obtained the model of orbital wall fracture. With mirror image repair technique, the fracture area of the affected side was reconstructed with the normal orbital wall shape of the opposite side. The model of fractured orbit and the patch of repair model with individualized shape were printed with 3D printer which was used as template to guide bioresorbable plate shaping during the surgery. The orbital fracture was repaired with the after-shaping bioresorbable plate which accorded with the anticipated anatomical shape. The efficacy of repair was observed after the surgery. Results The postoperative CT showed that the efficacy of fracture repair was satisfactory and the repair matereial fitted well with fracture area. All patients had no visual impairment after surgery. The average measurement of enophthalmometric was (0.54±0.78) mm. Among 5 cases with diplopia before surgery, 4 cases recovered completely and only 1 case had residual slight peripheral diplopia.

The clinical data of 13 patients with orbital blowout fracture from Jul.2016 to Dec.2017 in Peking University International Hospital were analyzed. All patients received thin-slice spiral CT scanning. The data were used to three-dimensional reconstruction and obtained the model of orbital wall fracture. With mirror image repair technique, the fracture area of the affected side was reconstructed with the normal orbital wall shape of the opposite side. The model of fractured orbit and the patch of repair model with individualized shape were printed with 3D printer which was used as template to guide bioresorbable plate shaping during the surgery.

Objective To observe the efficacy of pranoprofen eye drops in the treatment of Meibomian gland dysfunction. Methods Clinical case-control study.Total of 62 eyes of 42 cases with Meibomian gland dysfunction in Huaxian People’s Hospital from May 2017 to Jun.2017 were randomly divided into two groups.There were 31 eyes of 21 cases in artificial tears group and 31 eyes of 21 cases in the pranoprofen eye drops group.The two groups were treated with artificial tears(4 times a day) or pranoprofen eye drops (3 times a day) for 1 month, respectively.The efficacy was observed at 1 month after treatment. Results The tear break-up time in the artificial tear group was ameliorated compared with that before treatment(t=2.211, P=0.033). The ocular symptoms, break-up time and corneal fluorescein staining in the pranoprofen group were significantly ameliorated compared with those before treatment(t=2.102, 2.401, 2.385, P=0.046, 0.018, 0.022). The difference of corneal fluorescein staining was not statistically significant between the two groups. Conclusion Non-steroidal anti-inflammatory eye drops therapy is effective for patients with Meibomian gland dysfunction. Key words: Dysfunction, Meibomian gland; Eye drops, pranoprofen; Treatment
