Abstract

Takayasu's arteritis (TKA) is a chronic, granulomatous, systemic vasculitis affecting the aorta and its branches. Ocular manifestations in patients with TKA play an important role in determining the visual prognosis. We describe a case of a young female with complaints of painless, progressive loss of vision in both eyes for 6 months who was clinically diagnosed with TKA. Her laboratory and radiological investigations confirmed the diagnosis. She had a bilateral cataract and operated for cataract in the right eye with guarded visual prognosis. This case report highlights the importance of creating awareness among ophthalmologists for early diagnosis and multidisciplinary management in cases of TKA for the prevention of blindness.

Introduction

Takayasu's arteritis (TKA) is a chronic, granulomatous, systemic vasculitis affecting the aorta and its branches, coronary and pulmonary artery leading to occlusion and stenosis of the involved arteries.^[1] It predominantly affects women and occurs in second and third decades of life.^[2] It was first described by a Japanese Ophthalmologist Mikito Takayasu in 1908 in a 21-year-old female with wreath-like appearance of blood vessels in the retina along with absent radial pulse.^[3]

The prevalence of ocular manifestations in TKA is varied ranging from 8.1% to 68%.^{[4],[5],[6],[7]} The signs of anterior segment ischemia including shallow anterior chamber, corneal edema, iris neovascularization, and glaucoma are seen along with posterior segment findings such as microaneurysms, cotton wool spots, small vessel dilatation, and retinal neovascularization.^[8]

Although Takayasu's retinopathy and hypertensive retinopathy are primarily noted, cataract appears to be a rare ocular finding reported in 1%–2% of patients.^[7],[8],[9] Here, we report a case of TKA with bilateral cataract and its multidisciplinary management.

Case Report

A 21-year-old female presented with painless diminution of vision for 6 months. She was a diagnosed case of TKA in April 2020 and was on oral methotrexate 15 mg once weekly. In November 2020, she had an acute episode of cerebrovascular accident for which she was hospitalized and treated. In May 2021, she complained of a gradual decrease of vision in both eyes and was diagnosed with branch retinal vein occlusion by a local doctor.

On examination, she was conscious, thinly built, and weighed 30 kg. Her pulse rate was 78 beats/min, blood pressure of 100/70 mmHg in the right upper limb, and 90/60 mmHg in the left upper limb, and oxygen saturation of 98% in room air. Radial pulse was not detectable in both upper limbs and was recordable in lower limbs. Cardiac, neurological, and respiratory examination was normal.

Visual acuity was perception of light with inaccurate projection of light in both eyes. Pupils were fixed, mid-dilated, and nonreactive to light in both eyes. The anterior chamber was quiet. A total cataract was noted in both eyes [Figure 1]. Intraocular pressure was 14 mmHg in both eyes. B scan ultrasonography was normal [Figure 2]. A diagnosis of bilateral cataract secondary to TKA was made and physician consultation advised.

Laboratory investigations for blood sugar, liver function test, kidney function test, thyroid profile, urine examination, and coagulation profile were within normal limits. Hemoglobin was 10.2 g/dl, erythrocyte sedimentation rate (ESR) was raised at 38, and C-reactive protein (CRP) was raised at 25 mg/L. Serology for human immunodeficiency virus, hepatitis B and C, venereal disease research laboratory for syphilis, antinuclear antibody, and rheumatoid factor were negative. The Mantoux test was negative.

Her previous computerized tomography angiography of the head and neck revealed circumferential wall thickening with near-complete narrowing of left subclavian, left common carotid artery (CCA), brachiocephalic trunk, bilateral CCA, and coeliac trunk at origin. Magnetic resonance imaging of the brain showed acute infarct in the left anterior cerebral artery and middle cerebral artery (MCA) [Figure 3]. There were multiple infarcts, gliosis, encephalomalacia, and cortical necrosis suggestive of old MCA infarct [Figure 4]. Magnetic resonance angiography reported nonvisualization of the left internal carotid artery and faint visualization of the right internal carotid artery with significant narrowing of the posterior branch of the left MCA with a paucity of cortical branches [Figure 5].

The patient was admitted to medical ward as she was in the acute phase of disease activity and was started on oral Cefixime 200 mg twice daily for 5 days and prednisolone 20 mg in tapering doses. Methotrexate 15 mg once weekly, folic acid 5 mg twice weekly, and baclofen 10 mg thrice daily were also administered orally. ESR and CRP were repeated every 72 h and it was showing a declining trend. She underwent an uneventful small incision cataract surgery in her right eye with no visual improvement and lost to follow-up.

Discussion

Ocular changes in TKA are due to ischemia depending on the part of carotid arteries occluded, duration of ocular vascular insufficiency, and efficient functioning of collaterals in the eye.^[4] There are case reports of retinal manifestations in the form of central or branch retinal artery occlusion, branch retinal vein occlusion, hypertensive retinopathy, and acute ischemic optic neuropathy.^{[10],[11],[12],[13],[14]}

A cataract is rare and late presentation of TKA. Literature search using the words TKA, pulseless disease, cataract, retinopathy in PubMed, Embase, and Google scholar showed few case reports as described in [Table 1].^[9],[15] Harada et al. reported a case of a 34-year-old female of TKA who had a poor visual outcome after cataract surgery.^[9] Flores-Suarez et al. reported three cases of TKA in females aged 25–34 years presenting with complaints of diminution of vision in all cases and involving both the eyes in two cases. The symptoms were present for 5 months and had not received any treatment. Besides bilateral cataract, two of the patients had severe Takayasu's retinitis which the author's thought was due to ischemia that developed before the cataract.^[15] The technique of cataract surgery did not differ from routine phacoemulsification but caution must be kept for intraoperative hyphaema despite no signs of iris and angle neovascularization.^[16] Postoperative uveitis needs to be taken care by use of prednisolone acetate 1% eye drops tapered by 2 weeks and noninflammatory steroids eye drops to be continued for 3–4 weeks. There are few cases reported till date,^{[7],[9],[15],[16],[17]} and our case was also a young female with bilateral cataract.

There are multiple causes of cataracts in TKA. Long-term use of steroids in the treatment of TKA can be one of the reasons for steroid-induced cataract.^[6] Harada et al. reported that due to severe ischemia there was excessive production of vascular endothelial growth factor (VEGF) which can lead to cataractous changes.^[9] Some theories even suggested that alteration in the nutrition of lens due to circulatory disturbances, neuroreceptor damage, and anterior ischemic changes can also be attributing factors in the development of cataract.^[15],[18] Visual prognosis after surgical intervention is poor due to Takayasu's retinopathy, retinal ischemia, and optic atrophy which was seen in our case.

This case report is unique in establishing the fact that although cataract is a rare in TKA, timely intervention is needed as they are young patients. TKA patients must undergo a routine ocular examination to detect the findings early and intervention in the form of laser photocoagulation, anti-VEGF injections, or surgery for retinopathy can help in restoring sight. A high index of suspicion and awareness among ophthalmologists is needed in the diagnosis and multidisciplinary management of this disease.
