Objective To observe the clinical features and treatment outcomes of presumed tubercular retinal vasculitis. Methods This is a retrospective non-comparative interventional clinical research. A total of nine patients (11 eyes) with major presentation of retinal vasculitis were included in this study. Patients first consulted the eye clinic and were diagnosed presumed tubercular retinal vasculitis. The patients, seven males and two females, aged from 19 to 66 years, with an average of 43.89 years. The time interval from symptoms to diagnosis ranged from two weeks to six months with an average of 76.27 days. Visual acuity, slit lamp ophthalmoscopy, fundus fluorescein angiography (FFA), optical coherence tomography (OCT), hematological and tuberculosis related investigations were examined and analyzed. All patients had standard anti-tuberculosis treatment. Treatment outcomes were followed for six to 37 months with an average of 14.11 months. Results Baseline visual acuity ranged from hand movement to 0.8 with an average of 0.28. Among 11 eyes, six presented mild to moderate vitritis, five presented as retinal vein occlusion with no obvious vitirits. Fundus examination showed six cases with retinal hemorrhage, four cases with macular edema, two with macular epiretinal membrane, and two with vitreous hemorrhage. FFA revealed 11 cases with leakage of vessels, 11 with nonperfusion area, four with macular edema, three with retinal neovascularization, and two with choroidal lesions. OCT of nine eyes suggested six eyes with retinal edema, three with macular edema, three with macular epiretinal membrane. TST of seven patients were all b positive. T-SPOT.TB of four patients were all positive. Three of eight patients who had chest X-ray or chest CT were suggested tuberculosis infection. Four to six weeks after the start of anti-tuberculosis treatment, vitritis, exudates, retinal and macular edema subsided. During follow up, inflammation was stable with no recurrence observed. The visual acuity of last follow-up ranged from 0.15 to 0.8 with an average of 0.51. Conclusions The main presentations of presumed tubercular retinal vasculitis are vitritis, retinal vein occlusion, and retinal hemorrhage. Standard anti-tuberculosis treatment can improve inflammation and retinal hemorrhage.
Objective To analyze the association between histocompatibility leukocyte antigen （HLA-A/B,HLA-DRB/DQB） alleles and Eales disease, and to explore susceptible genes and protective genes associated with Eales disease in a population of Han from ZUN YI city in Guizhou province. Methods The subjects were analyzed by casecontrol study consisted of two groups such as normal control group and Eales disease group. DNA samples from 100 healthy people and 26 patients with Eales disease were detected by polymeriase chain reaction with sequencespecific primers (PCR-SSP). The alleles of HLA-A/B and HLA-DRB/DQB from Eales disease group were compared with those from control group by SPSS 13.0. Results The distribution frequency in Eales disease was HLAA01(P=0.041, OR=20.5), A02(P=0.000, OR=54.667, OR 95%CI:11.837-252.473), B55 (P=0.047, OR=4.524; OR 95%CI:1.200-17.047), HLA-DRB01(P=0.048, OR=5.879, OR95%CI:1.227-28.169). DQB05 (P=0.021, OR=2.769, OR95%CI=1.145-6.692) alleles, and obviously higher than control, but the frequency of HLAA11 (P=0.031, OR=0.383, OR95%CI=0.158-0.930) was obviously lower than control (P＜0.05). Conclusion The results showed that the alleles of HLAA01, A02, B55, DRB01, DQB05 may associate with an antagonist effect in Eales disease, but HLAA11 may be a protective gene of this disease.
Objective To investigate the characteristics of fundus photography and fundus fluorescein angiography (FFA) of IRVAN (idiopathic retinal vasculitis, aneurysms, and neuroretinitis) syndrome and Eales disease. Methods The fundus photography and FFA data of 4 cases (8 eyes) with IRVAN syndrome and 43 cases (68 eyes) with Eales disease were retrospectively analyzed. All patients received ophthalmic routine examinations, including visual acuity, intraocular pressure, slit-lamp microscope and indirect ophthalmoscope. All patients had taken fundus photography and FFA for both eyes, except 4 patients of Eales disease who had vitreous hemorrhage in one eye. All 4 cases(1 male/3 female )with IRVAN syndrome were bilateral and aged 1643 years old( mean age 2700plusmn;1293 years old). 43 cases (32 male/11 female) of Eales disease aged 6-59 years old( mean 30.79plusmn;11.46 years old), 29 cases were bilateral and 14 cases were unilateral. Both diseases had retinal vascular whitesheath or white threadlike changes, exudative retinal hemorrhage and vitreous hemorrhage. Results Both arteries and veins of posterior pole of all eyes with IRVAN syndrome were involved and shown multiple retinal macroaneurysms. Other signs of IRVAN syndrome included capillary occlusion and nonperfusion (7/8 eyes, 87.5%),fluorescein leakage and edema of optic disc (5/8 eyes,62.5%), optic atrophy(2/8 eyes,25%), vitreous hemorrhage(1/8 eyes,12.5%), neovascularization of optic disc(2/8 eyes,25%), retinal neovascularization(4/8 eyes,50%) and macular edema(4/8 eyes,50%). The signs of Eales disease included fluorescein leakage of peripheral retinal vein (68/68 eyes, 100%), fluorescein leakage of posterior retinal vein (32/68 eyes, 47.06%), artery involvement (5/68 eyes, 7.35%), peripheral capillary occlusion and nonperfusion (38/68 eyes, 55.88%), fluorescein leakage of optic disc(29/68 eyes, 42.65%), neovascularization of optic disc(4/68 eyes,5.88%), retinal neovascularization(26/68 eyes,38.2%) and macular edema(15/68 eyes,22.06%). Compared IRVAN syndrome with Eales disease, the difference of artery inflammation, vein inflammation, retinal macroaneurysms in posterior area had statistics significance(all P=000,Plt;005), and that of edema of optic disc, retinal vascular nonperfusion area, neovascularization of optic disc, neovascularization elsewhere, and macular edema had no statistics significance(chi;2=0.479，P＞0.05；P=0.131，P＞0.05；chi;2=1.449，P＞0.05；chi;2=0.068，P＞0.05；chi;2=1.676，P＞0.05). Conclusions Both IRVAN syndrome and Eales disease may have vein and artery inflammation in posterior pole of the eye, and may result in neuroretinitis. IRVAN syndrome has much more vein and artery inflammation in posterior pole than Eales disease. Posterior retinal macroaneurysms is the most important sign for the diagnosis and differential diagnosis of IRVAN syndrome and Eales disease.
Objective To observe the clinical characteristics of idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome. Methods The clinical data of 3 patients with IRVAN syndrome which were diagnosed by systemic examination, fundus photography and fundus fluorescein angiography (FFA) were retrospectively analyzed. Results Idiopathic retinal vasculitis, which was induced by retinal arterial inflammation, multiple macroaneurysms of optic disc and retinal vessels, edema of optic disc, and exudation around the optic disc, was found in all of the 3 patients, multiple arteriolar aneurysms of optic disc and retinal vascular and exudative neuroretinitis. Two patients had peripheral retinal vascular nonperfusion area, which belonged to typical IRVAN syndrome. Conclusions The clinical characteristics of IRVAN syndrome include idiopathic retinal vasculitis which only involved in artery, multiple retinal macroaneurysms which located on the dissepiment of optic disc and retinal artery, and the neuroretinitis induced by exudation of retina and optic disc because of vasculitis and aneurysms.

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.
