  • Multimodal imaging characteristics for presumed tuberculous retinal vasculitis

    Objective To observe the multimodal imaging characteristics of the eyes in patients with presumed tuberculous retinal vasculitis. Methods A retrospective case series study. A total of 15 patients (22 eyes) diagnosed with presumed tuberculous retinal vasculitis and receiving anti-tuberculosis treatment (ATT) effectively in Department of Ophthalmology, Subei People's Hospital Affiliated to Yangzhou University from January 2018 to April 2021 were included. Among them, there were 5 males and 10 females. Seven had bilateral involvement and 8 had unilateral involvement. The age was 49.3±11.1 years old. The best corrected visual acuity (BCVA), fundus colour photography, wide-angle fundus fluorescein angiography (FFA), and optical coherence tomography (OCT) were performed in all patients. Indocyanine green angiography (ICGA) was performed in 7 eyes. The BCVA examination was performed with the international standard visual acuity chart, which was converted into the logarithm of minimal angel resolution vision (logMAR). Systemic tuberculosis-related examinations included chest CT, serum T-spot, purified protein derivative and other tuberculosis-related tests. All patients were treated with systemic anti-tuberculosis therapy. The follow-up time was >12 months. The multimodal imaging characteristics for affected eyes. Nonparametric test was used to compare BCVA before and after treatment. ResultsThe retinal vessels of all the affected eyes were tortuously dilated, including 3 eyes with vascular white scabbard, 5 eyes with scattered bleeding point at the retina inculding 3 eyes walking along the vessels. The lesions were mainly distributed in the middle and periphery of the retina, and some of them involved the posterior pole; 12 eyes (54.5%, 12/22) with simple retinal vasculitis and 10 eyes (45.5%, 10/22) with retinal vasculitis complicated with choroiditis. Tuberculous retinal vasculitis showed different degrees of retinal vascular leakage on FFA, mainly retinal vein and capillary leakage, not involving arteries; 16 eyes (72.7%, 16/22) of retinal vasculitis showed peripheral occlusive retinal vasculitis and 4 eyes (18.2%, 4/22) were associated with retinal neovascularization. In 10 eyes with choroiditis, there were multiple focal choroiditis lesions of different sizes under the retina. Of the 7 eyes examined by ICGA, the choroidal inflammatory lesions showed hypofluorescent dark dots (HDD) in 5 eyes (71.4%,5/7), showing HDDs of different sizes, most of which were distributed in the posterior pole and middle periphery. In 10 eyes with retinal vasculitis complicated with choroiditis after ATT, the accumulation of hyper-reflective substances above and below the retinal pigment epithelium layer of the retina was gradually absorbed, but not completely disappeared, and most of the disorders of retinal structure could not be recovered. The average logMAR visual acuity was 0.61±0.57 before treatment and 0.36±0.55 after treatment. The BCVA after treatment was significantly higher than that before treatment (Z=-3.102, P<0.01). ConclusionsPeripheral occlusive retinal vasculitis is the most common manifestation of tuberculous retinal vasculitis in FFA, which may be accompanied by focal choroidal inflammatory lesions. Wide-angle FFA and ICGA are more important in the diagnosis of tuberculous retinal vasculitis. OCT can be used for monitoring the changes of inflammation.

  • Preliminary evaluation of the safety of the lens and the ora serrata during vitrectomy with scleral incisions at 5.0 mm behind the limbus

    ObjectiveTo evaluate the safety to perform 23G vitrectomy with scleral incisions at 5.0 mm behind the limbus.MethodsThis is a prospective uncontrolled case study. The data of 140 consecutive primary 23G vitrectomy patients (145 eyes) were enrolled in this study. There were 56 males (59 eyes) and 84 females (86 eyes), with the mean age of (56.34±9.98) years and axial length of (23.99±2.57) mm. There were 139 phakic eye and 6 aphakic eyes. All the eyes received 23G pars plana vitrectomy with scleral incisions at 5.0 mm behind the limbus. To measure the normal Chinese adult parameters of anteroposterior axis of the eyeball, lens thickness and scleral distances from the limbus to the plane passing through the lens posterior apex, the head CT scans of 105 patients without eye diseases in our hospital were studied during the same period of time for these vitrectomy surgeries. Pearson correlation analysis was used to analyze the relationship between age, anteroposterior axis of eyeball, lens thickness and scleral distances from the limbus to the plane passing through the lens posterior apex.ResultsSurgical related complications included retinal tears close to the scleral incision sites (3/145 eyes, 2.1%) and lens injury (3/121 eyes, 2.5%). No other surgical complications occurred, such as retinal hemorrhage, supra-choroidal expulsive hemorrhage and iatrogenic retinal detachment. Based on CT images, the average scleral distance from limbus to the plane passing through the lens posterior apex, anteroposterior axis of eyeball and lens thickness was (6.72±0.81), (24.39±0.97), (4.22±0.47) mm, respectively. The results of Pearson correlation analysis showed that age and lens thickness had statistically significant correlation (r=0.328 9, P=0.000 6).ConclusionPrimary 23G pars plana vitrectomy with incisions at 5.0 mm posterior to the limbus is safe.

  • Management of non-inferior rhegmatognous retinal detachment with vitrectomy and air tamponade

    ObjectiveTo observe the outcomes of 23G pars plana vitrectomy (PPV) and air tamponade for non-inferior rhegmatognous retinal detachment (RRD).MethodsA prospective case series study. From August 2017 to April 2018, 39 consecutive RRD patients (39 eyes) in Department of Ophthalmology of Subei People’s Hospital Affiliated to Yangzhou University were enrolled in this study. There were 20 males (20 eyes) and 19 females (19 eyes), 23 right eyes and 16 left eyes, with the mean age of 55±11 years. There were 30 eyes with lens and 9 eyes without lens or IOL. There were 21, 14 and 4 eyes with 1, 2 and equal or greater than 3 retinal tear respectively. All patients underwent 23G PPV which performed preretinal proliferative membranes and vitreous cortex removal, photocoagulation around the breaks with 3-5 rows, and filtered air tamponade. The follow-up was more than 2 months. The retinal reattachment, visual acuity and complications were observed. Pearson correlation analysis was used to analyze the correlation between BCVA and disease course. Chi-square test was performed for comparison among retinal reattachment rate and different clinical factors before operation.ResultsAt 2 months after the PPV, 35 eyes’ retina reattached, the rate of reattachment was 89.8%. In 2-3 weeks, 4 eyes were re-detached, all of them performed silicone oil tamponade. One eye was secondary to pre-macular membrane. The logMAR BCVA before and after PPV were 1.15±0.78 and 0.41±0.31, respectively (t=6.589, P=0.0001). Correlation analysis results showed that BCVA after surgery was positively correlated with BCVA before surgery (r=0.544, P=0.001). Twelve of 30 eyes with crystalline lens suffered cataract. The rate of reattachment vary in the number of the breaks (χ2=9.181, P=0.010).ConclusionPPV with air tamponade may be an optimal treatment of non-inferior RRD with better success rate and security.
