    1. Optical Coherence Tomography as a Diagnostic Adjunct for Ocular Surface Lesions

      Optical Coherence Tomography as a Diagnostic Adjunct for Ocular Surface Lesions

      We describe a series of four cases with ocular surface lesions, where optical coherence tomography (OCT) proved to be a useful tool for diagnosis and/or management. These cases included pterygium with cyst, suspected ocular surface squamous neoplasia, nodular scleritis and an inclusion cyst. The ability of OCT to reveal the internal characteristics and the true location of lesion may help, in judicious decisions regarding excisional biopsy in future.

      Swept source optical coherence tomography-angiography of an infarct of a small intra-neural branch of central retinal artery simulating cilio-retinal artery

      A 56-year-old man with episodic transient visual loss in right eye (OD), of 2 days duration. He was not symptomatic at presentation and was using anti-coagulants for cardiovascular disease. Visual acuity was 6/6 both eyes (OU). Intra-ocular pressure and anterior segment were normal OU. OD had a finger like area of macular whitening sparing the fovea. This area corresponded to the vascular bed of a clinically appearing cilio-retinal artery (cilio-RA) [Figure 1] a. However, on fluorescein angiography, the artery filled along with branches of central RA (CRA) [Figure 1] b and [Figure 1] c. Swept source optical coherence tomography ...

    3. Swept-source optical coherence tomography of an optic disc melanocytoma: The importance of the hyperreflective foci

      Swept-source optical coherence tomography of an optic disc melanocytoma: The importance of the hyperreflective foci

      Optic disc melanocytoma (ODM) has been considered as a benign tumor with few reports of malignant transformation. We present swept-source optical coherence tomography (SSOCT) imaging of a case of ODM. As attaining histopathology is impossible in most cases, we discuss the possibility of using SSOCT as a tool for ruling out choroidal invasion or juxtapapillary melanoma.

    4. Peripheral optical coherence tomography montage guided successful management of retinal detachment with sub retinal bands

      Peripheral optical coherence tomography montage guided successful management of retinal detachment with sub retinal bands

      Sub Retinal Bands (SRB) often complicate old Rhegmatogenous Retinal Detachments (RRD). We discuss the utility of Optical Coherence Tomography (OCT) montage in such a case of a 23 year old female who presented with BCVA of 20/40 in OS with a complicated cataract. She was found to have a shallow subtotal RRD in left eye extending till temporal ora serrata with macula off and a SRB extending across the temporal vascular arcades with superotemporal lattice with holes. The RD appeared to be self-settling peripherally due to pigmentary changes. OD was normal. RRD was imaged with OCT montage. The Neuro ...

    5. Blood flow pattern in a choroidal hemangioma imaged on swept-source-optical coherence tomography angiography

      Blood flow pattern in a choroidal hemangioma imaged on swept-source-optical coherence tomography angiography

      This report demonstrates the blood flow pattern in a case of choroidal hemangioma (CH) using swept-source-optical coherence tomography angiography (SS-OCTA). Fluorescein angiography, SS-OCT, and SS-OCTA images of a patient with CH were obtained using a standard protocol. The internal vascular pattern of the tumor was identified on both OCT and OCTA. Dark areas were identified in the CH. These were interspersed between areas of visible blood flow, as imaged on SS-OCTA. Peripheral vascular arcades were also identified within the tumor. SS-OCTA should be evaluated as an imaging tool to study the blood flow within choroidal tumors.

    6. Optic disc coloboma with pit treated as glaucoma: diagnostic utility of ultrasound and swept source optical coherence tomography

      Optic disc coloboma with pit treated as glaucoma: diagnostic utility of ultrasound and swept source optical coherence tomography

      A 6-year-old boy presented as a known case of developmental glaucoma and was using topical travoprost in the right eye (RE) since 1 year. Highest recorded intraocular pressure (IOP) was 24 mm Hg in RE, whereas central corneal thickness was 540 µm. Visual acuity was 6/6 in both eyes. On examination, the anterior segment of both eyes was unremarkable. IOP was 16 mm Hg in RE and 20 mm Hg in the left eye. Fundus examination of RE revealed a large and pale optic disc, with a nearly absent inferior neuroretinal rim. The origin of the inferior vascular bundle ...

    7. Aborted choroidal coloboma: fundus imaging and optical coherence tomography

      Aborted choroidal coloboma: fundus imaging and optical coherence tomography

      Choroidal coloboma is characterised by poor embryonic development of chorioretinal structures and is of different types. We present a case of choroidal coloboma where the retinal pigment epithelium was present, clinically and on imaging, but rest of the structures were poorly formed. This observation suggests that in some cases, fusion of the fetal cleft may occur aberrantly, resulting in an aborted choroidal coloboma. .

    8. Optical coherence tomography of the Kayser-Fleischer ring: an ancillary diagnostic tool for Wilsons disease in children

      Optical coherence tomography of the Kayser-Fleischer ring: an ancillary diagnostic tool for Wilsons disease in children

      This report presents anterior segment optical coherence tomography (AS-OCT) images of Kayser-Fleischer ring (KFR) in a child. The AS-OCT images highlight differential reflectivity of the KFR depending on amount of copper deposited in cornea, thus supporting the role of AS-OCT as a follow-up tool. Utility of AS-OCT for diagnosing and documenting the KFR in children otherwise uncooperative for detailed slit lamp examination is discussed.

    9. Ultra-wide Field Imaging and Swept Source Optical Coherence Tomography of Ocular Electrical Injury in a Child

      Ultra-wide Field Imaging and Swept Source Optical Coherence Tomography of Ocular Electrical Injury in a Child

      History of trauma in children may be obscured and physicians often rely on signs for diagnosis. The authors discuss a case of electrical injury where ocular signs led to diagnosis of the cause of macular atrophy. A high index of suspicion must always be maintained in such atypical cases, and the setting of electrical injury to the body requires meticulous ocular examination.

    10. Anterior segment optical coherence tomography for identifying muscle status in strabismus surgery

      Anterior segment optical coherence tomography for identifying muscle status in strabismus surgery

      Dear Sir, Anterior segment optical coherence tomography (AS-OCT) finds very few indications in the domain of strabismus surgery. Current applications remain restricted to determining limbus-muscle insertion distance and anterior segment changes after strabismus surgery. We discuss two cases of operated strabismus surgery where AS-OCT imaging helped in identifying the operated eye and/or extra ocular muscles (EOM) and thus proved instrumental in planning and management. Case 1 A 45 years old orthotropic male presented with post traumatic left eye rhegmatogenous retinal detachment. He had history of strabismus surgery in the left eye in childhood for exotropia. He was planned for ...

    11. Swept source: optical coherence tomography angiography features of choroidal osteoma with choroidal neovascular membrane

      Swept source: optical coherence tomography angiography features of choroidal osteoma with choroidal neovascular membrane

      A 16-year-old boy presented with best-corrected visual acuity of 6/18 OD. OS was within normal limits, as was anterior segment OD. A focal whitish-yellow plaque lesion with overlying areas of depigmentation, and retinal atrophy in the central and superior lateral macula were noted in OD. A choroidal neovascular membrane (CNVM) with subretinal haemorrhage was seen at the lesion's inferior medial edge, involving the fovea (figure 1A). Therefore, diagnosis of choroidal osteoma 1 (CO) was made and confirmed on sonography, with a highly acoustic elevated lesion causing a corresponding shadow (figure 1B).

      Three-dimensional Enhanced Imaging of Vitreoretinal Interface in Diabetic Retinopathy Using Swept-Source Optical Coherence Tomography

      The article “Three-dimensional Enhanced Imaging of Vitreoretinal Interface in Diabetic Retinopathy Using Swept-Source Optical Coherence Tomography” by Adhi and associates 1 discusses the utility of swept-source optical coherence tomography (SSOCT) in imaging vitreoretinal interface in diabetic patients. The authors have used a vitreous windowing method and motion correction algorithms for enhancement of vitreous imaging.
