Atopic Dermatitis Associated Retinal Detachment and Retinal Vasculitis: A Case Report.

Atopic dermatitis is usually associated with various ocular complications. We report a 21-year-old Chinese male who presented to our ophthalmology clinic with bilateral retinal detachment and cataracts. The patient had a clear medical history of atopic dermatitis, which had been diagnosed eight years earlier and had been treated with loratadine and pimecrolimus. Cataract surgery was performed for both eyes, combined with scleral buckling for the right eye and pars plana vitrectomy for the left eye. During postoperative follow-up, fundus fluorescein angiography showed retinal vasculitis in both eyes and macular edema in the left eye, which coincided with an exacerbation of atopic dermatitis. Macular edema improved after four months of regular dupilumab treatment in the dermatology department. The ocular condition remained stable three years postoperatively.

Central and Peripheral Changes in Retinal Vein Occlusion and Fellow Eyes in Ultra-Widefield Optical Coherence Tomography Angiography.

Purpose: To explore the central and peripheral retinal and choroidal changes in retinal vein occlusion (RVO) and fellow eyes using ultra-widefield swept-source optical coherence tomography angiography (UWF-SS-OCTA). Methods: Fifteen ischemic central RVO (CRVO), 15 branch RVO (BRVO), and 15 age-matched healthy controls were prospectively recruited. Retinal and choroidal parameters, including retinal vessel flow density (VFD) and vessel linear density (VLD), choroidal vascularity volume (CVV), choroidal vascularity index (CVI), and VFD in the large and medium choroidal vessels (LMCV-VFD), were measured in the central and peripheral regions of the 24 × 20-mm UWF-SS-OCTA images. Results: Ischemic CRVO and BRVO eyes showed increased foveal avascular zone area, perimeter, and acircularity index (AI) compared to their fellow eyes and healthy control eyes, and RVO fellow eyes also had larger AI values than controls (P < 0.05). For ischemic CRVO and BRVO eyes versus control eyes, VFD, VLD, CVV, CVI, and LMCV-VFD decreased, but retinal thickness and volume in the superficial capillary plexus, deep capillary plexus, and whole retina increased (P < 0.05). Moreover, RVO fellow eyes also showed significantly decreased retinal VFD, LMCV-VFD, and CVI, as well as increased retinal thickness and volume, compared with control eyes (P < 0.05). Alterations were not consistent throughout the retina, as they involved only the peripheral or central regions in some cases. Conclusions: The affected and unaffected fellow eyes of RVO patients both demonstrated central and/or peripheral structural and vascular alterations in the retina and choroid. Because UWF-SS-OCTA enables visualization and evaluation of the vasculature outside the posterior pole, it presents a promising approach to more fully characterize vascular alterations in RVO.

Impacts of angiotensin II on retinal artery changes in apolipoprotein E deficient mice.

AIM: To investigate the impacts of angiotensin II (Ang II) on retinal artery changes in apolipoprotein E deficient (apoE-/-) mice. METHODS: apoE-/- male mice were infused by minipumps with Ang II at 1000 ng/kg·min (Ang II group) or saline (control group) for 28d. They were underwent ophthalmic fundus examination on day 0, 14, and 28 of infusion. Histopathologic examination, ribonucleic acid (RNA) sequencing and local Ang II measurement of retinas were conducted. RESULTS: Ophthalmic fundus examination showed Ang II infusion promoted the formation of retinal arterial aneurysm-like lesions on day 28. Optical coherence tomography revealed the ganglion cell and inner plexiform layer (GCIPL) thickness in the control group was significantly thinner than that in Ang II group (P<0.001). Hematoxylin-eosin staining demonstrated diffused swelling of GCIPL layer and its disordered structure in Ang II group. Transmission electron microscopy showed Ang II infusion caused aggravation of atherosclerotic lesions, including increased swelling, roughness, disorganization of the retinal vasculature, and vacuoles formation. RNA-sequencing and gene ontology enrichment analysis demonstrated that the structure and function of cellular membrane might be disturbed and visual function might be compromised by Ang II. The local level of Ang II was higher in Ang II infusion group but did not show significant differences compared to the control group (P=0.086). CONCLUSION: Ang II infusion promotes the formation of retinal arterial aneurysm-like lesions in apoE-/- mice, causing aggravation of atherosclerotic lesions, more severe disorganization of the retinal vasculature and disturbance of the cellular membrane.

The incidence, risk factors, management and prognosis of postoperative systemic complications after ophthalmic surgery: a retrospective study at a tertiary, academic referral hospital over a decade.

PURPOSE: To explore the incidence, risk factors, management and prognosis of systemic complications after ophthalmic surgeries. METHODS: A retrospective review of hospitalized patients undergoing ophthalmic surgeries between 2012 and 2022 at Peking Union Medical College Hospital was performed to summarize and analyse the postoperative systemic complications. Multivariate logistic and linear regression analyses were conducted to clarify the risk factors of postoperative systemic complications and factors associated with the severity of adverse events. RESULTS: A total of 34,841 patients underwent inpatient ophthalmic surgery, among which 162 systemic complications occurred in 150 patients during postoperative hospitalization. The overall incidence rate was 0.4%, with cardiovascular events (48.1%), digestive events (13.6%) and fever (12.3%) being the leading causes. About 17.3% of the cases had conditions improved after observation, 19.1% after symptomatic treatment, 54.9% had consultation with specific intervention and 8.6% were transferred to the corresponding departments for specialized treatment. For the prognosis, 93.8% had condition improved, 5.6% chose voluntary discharge without improvement, and one patient died of respiratory failure caused by postoperative pulmonary infection. The worse ADL (activities of daily living) grading, indication of primary intraocular lymphoma or intraocular tumour, surgery of simple pars plana vitrectomy (PPV), PPV with silicone oil tamponade, PPV with gas tamponade, general anaesthesia, history of diabetes mellitus (DM), chronic heart failure and digestive system disease were the risk factors positively correlated with postoperative systemic complications (p < .05). The worse ADL grading, history of DM and respiratory system disease were also positively correlated with the severity of the adverse events (p < .05). CONCLUSIONS: The incidence of postoperative systemic complications was low among patients undergoing ophthalmic surgery, most were mild and could be relieved after observation, symptomatic or specialist consultation. Patients with worse ADL and history of DM should be paid extra attention.

CLINICAL CHARACTERISTICS OF EALES DISEASE AND THE EFFICACY OF DIFFERENT INTERVENTIONS FOR NEOVASCULAR COMPLICATIONS.

PURPOSE: To evaluate clinical features and manifestations of Eales disease and the efficacy of different interventions. METHODS: The databases PubMed, EMBASE, and Ovid from inception until February 2021 were searched. Pooled analyses included 1) presenting features, 2) symptoms and signs, and 3) postoperative vision outcomes and complications. Statistical analyses were conducted with R software version 3.6.3. RESULTS: Forty-seven studies involving 3,557 patients and 4,959 eyes were included. The pooling results showed that Eales disease was male dominated (94%), bilateral involvement (64%), and mainly occurred in adolescents. Approximately 83% of patients were positive in Mantoux test, and 31% of patients have vitreous tap polymerase chain reaction positive for tuberculosis genome. More than half of the patients had decreased vision at the first clinic visit. The common signs of Eales disease included sclerotic vessels (83%), neovascularization of retina elsewhere (64%) and periphlebitis (51%). Macular changes could be detected in 24% of patients. The most common complication was vitreous hemorrhage, followed by cataracts and retinal detachment. Photocoagulation was directed at nonperfusion or neovascularization areas, with a decrease in the incidence of later pars plana vitrectomy (19%). Anti-vascular endothelial growth factor treatment was suggested for vitreous hemorrhage, which could achieve high visual acuity improvement rate (82%) while increasing the possibility of retinal detachment (18%). Pars plana vitrectomy was indicated in cases with persistent vitreous hemorrhage or retinal detachment, with 56% of patients obtaining visual improvement. Still, 17% of patients needed a second pars plana vitrectomy, mainly because of recurrent vitreous hemorrhage or retinal detachment. CONCLUSION: Eales disease most commonly affects young men. It has diverse clinical features, and management should be based on the progression of the disease.
