Objective To find out the follow-up results of early in-stent restenosis (ISRS) and develop effective way to improve clinical treatment and precaution of restenosis. Methods The data from a registry of 51 consecutive patients who underwent elective carotid artery angioplasty and stenting （CAS） at our institution between Jan. 2003 and Sept. 2005 were retrospectively reviewed. Complete data for 37 of these patients were available. All patients underwent duplex ultrasound scanning in follow-up period, which was used to determine the degree of restenosis. Results CAS was performed in 37 patients， 8.1% (3/37) were women. Mean age was (70.5±5.9) years. Mean time of follow-up was (12.2±7.7) months. Sixteen (43.2%) caces of ISRS （gt;30%） were found by color duplex ultrasound scanning， but only 1 (2.7%) ISRS was found gt;50%; 3 female patients had minor ISRS. Among all factors, female patients had higher incidence of ISRS than male (P=0.038); balloon-expanding after stenting and accompanying with other artherosclerosis of periphery vessel had correlation about ISRS （P=0.037, P=0.016）. Conclusion The severe restenosis rate is acceptable. Female patients were more likely to have ISRS. Balloon-expanding maybe have effect on reducing incidence of ISRS and controlling artherosclerosis was helpful.
Objective To analyze the surgical feasibility, operative key points and visual function recovery of scleral buckling in patients with rhegmatogenous retinal detachment (RRD) with large or giant retinal hole. Methods RRD patients with large or giant retinal hole who underwent scleral buckling in Chengdu Aidi Eye Hospital between January 1, 2019 and December 31, 2020 were retrospectively selected. The general data, complications and postoperative recovery of the patients were observed. Results A total of 344 inpatients (351 eyes) underwent scleral buckling with RRD, including 43 patients (43 eyes) with retinal detachment of large or giant hole. Among the 43 patients, there were 30 males (30 eyes) and 13 females (13 eyes); 42 cases were successfully operated and got retinal reattachment, and 1 failed. One week later, the patient underwent vitrectomy combined with silicone oil tamponade, and got retinal reattachment. No serious complications occurred in the patients after operation. The visual acuity of most patients improved after surgery. ConclusionsScleral buckling is still an effective method to treat RRD. It is still suitable for more patients as long as they are carefully checked before operation and the operators master the key points of operation. At the same time, more patients’ vitreous bodies can be preserved, and the normal structure and intraocular environment of the eyeball can be maintained.
ObjectiveTo investigate the therapeutic effects of vitrectomy for retinal detachment in patients with morning glory syndrome (MGS). MethodThe clinical data of 8 patients (8 eyes) who underwent vitrectomy for retinal detachment and MGS were retrospectively analyzed. Follow-up after treatment was performed for 8 months to 2 years. The visual acuity and retina reattachment were followed up. ResultsRetina was reattached in 5 eyes after vitrectomy. Retina was reattached in 2 eyes after second revision operation. Retina was not reattached in 1 eye after two operations. ConclusionsVitrectomy is effective in treating retinal detachment in patients with MGS.
ObjectiveTo analyze the clinical efficacy of scleral buckling surgery for rhegmatogenous retinal detachment (RRD) of 376 patients.MethodsA retrospective analysis was performed about 376 patients (391 eyes) who underwent scleral buckling surgery in Chengdu Aidi Eye Hospital from January 2018 to December 2019. There were 214 males (224 eyes) and 162 females (167 eyes). There were 15 binocular cases and 361 monocular cases. The average age was 37.16±16.36 years. The average course of disease was 3 months. There were 1 to more than 10 retina holes for all patients. Retinal breaks occur in all quadrants and at ora serrata. The preoperative average BCVA was 0.27 and the postoperative average BCVA was 0.41. Retinal detachment ranges was observed in 268 eyes in 1 quadrant, 97 eyes in 2-3 quadrants, 26 eyes in total, and 231 eyes with macular involvement. There were 376 eyes treated with scleral buckling, 9 eyes treated with scleral buckling combined with scleral encircling, 6 eyes treated with scleral encircling. The average follow-up time was 5 months. Postoperative follow-up was conducted to observe retinal reduction, BCVA, complications and patient compliance.ResultsAfter the first operation, retinal reattachmnents were successfully achieved in 375 eyes (95.91%); 16 eyes (4.09%) failed in retinal reattachmnents. Eight eyes were treated with scleral buckling again, 5 eyes were treated with vitrectomy silicone oil filling, and 3 eyes were treated with air injection. After the second operation, retinal reattachmnents were ultimately achieved in 16 eyes (100.00%). The average BCVA after operation was 0.15. Postoperative intraocular pressure increased by 45 eyes (11.51%). The intraocular pressure increased from the next day to 3 days after operation. The intraocular pressure was completely controlled 1-3 days after the treatment of topical medication and 20% mannitol. Vitreous and subretinal hemorrhage in 1 eye caused by drainage of the subscleral liquid. There was no cases withpostoperative infection.ConclusionThe retinal reattachment rate is 95.91% in 376 patients with RRD treated by scleral buckling surgery, and the visual acuity has significantly improved.
ObjectiveTo observe the clinical and fundus imaging features of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsA retrospective case study. A total of 32 eyes of 18 patients diagnosed of AMN associated with COVID-19 at Chengdu Aidi Eye Hospital from December 2022 to February 2023 were included. All patients had a history of fever 1 to 5 days prior to ocular onset and tested positive for SARS CoV-2 antigen. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, scanning laser ophthalmoscope (SLO), infrared fundus photography (IR), and optical coherence tomography (OCT); OCT angiography, visual field and multifocal electroretinogram (mf-ERG) were performed in 6 patients (11 eyes), 3 patients (6 eyes) and 1 patient (2 eyes), respectively. Follow-up time was 8-10 weeks. The clinical and fundus imaging features were observed and analyzed.ResultsThere were 6 males (12 eyes) and 12 females (20 eyes), aged from 15 to 36 years, with the mean age of (28.00±5.86) years. Fourteen patients were bilateral and 4 patients were unilateral. The time from the onset of eye symptoms to seeing a doctor was ranged from 1 day to 8 weeks. Among them, 6 patients (10 eyes) visited the doctor within 3 days of onset, while 12 patients (22 eyes) visited the doctor after 3 days of onset. The BCVA was 0.80±0.29. Fundus color photography and SLO examination showed that only 2 patients (4 eyes) showed sheet or petal-like dark red lesions in the macular area, and no obvious abnormal changes were observed in other patients. No obvious abnormalities were found in AF examination of all patients. IR examination showed no significant abnormality in 6 cases which came to hospital within 3 days after the onset, but irregular hyporeflective dark shadow lesions in the macular region of patients with more than 3-day course of disease was observed. OCT examinations of all eyes showed hyperreflective band or patchy lesion on the outer plexiform layer (OPL) and outer nuclear layer (ONL) and affect the ellipsoid zone (EZ) and interdigitation zone (IZ). In 11 eyes of 6 patients undergoing OCTA examination, the blood flow density of the choroidal capillary layer in the focal area decreased. In 6 eyes of 3 patients who underwent visual field examination, the physiologic scotoma was slightly enlarged. One patient (2 eyes) receiving mf-ERG showed a concave reduction in macular center amplitude. The hyperreflective band lesion on OPL and ONL disappear rapidly within 2 weeks, while the continuity of EZ recovered slowly, and the disruption of IZ kept existing for more than 10 weeks. ConclusionsMost AMN associated with COVID-19 are young women; IR showed irregular weak reflex in the lesion area. OCT showed strong OPL and ONL reflection. OCTA was characterized by decreased blood flow density in the choroidal capillary layer of the focal area.
