      Clinical role of swept source optical coherence tomography in anterior segment diseases: a review

      Purpose: To note the comprehensive role of swept source anterior segment optical coherence tomography (SS-ASOCT) in anterior segment diseases. Methods: A systematic literature search was carried out on various medical databases using the keywords, swept source anterior segment optical coherence tomography; SS-ASOCT; Cornea and SS-ASOCT; SS-ASOCT and glaucoma; SS-ASOCT and cataract; SS-ASOCT and biometer; SS-ASOCT and tear film and ocular surface.Original works and novel reports describing the potential role of SS-ASOCT in various anterior segment conditions were included. Results: After a thorough assessment of literature, it was clear that the SS-ASOCT did provide newer insights into many anterior eye ...

      Study 3: Assessment of events during surgery on posterior polar cataracts using intraoperative optical coherence tomography

      Purpose: To describe the changes along nucleo-epinuclear and the opacity-capsular junction during hydrodelineation and the entire period of phacoemulsification using intraoperative optical coherence tomography (iOCT). Methods: A total of 12 eyes of 12 patients with clinically confirmed posterior polar cataract, who underwent cataract surgery by a single surgeon under the direct guidance of iOCT. The changes along nucleo-epinuclear junction and opacity-capsular junction during/following hydrodelineation and the changes along the opacity-capsular junction following nucleus removal, capsular changes before the opacity removal, and its dynamic changes throughout the surgical procedure were studied. Results: The mean age of patients was 48.25 ...

      Intraoperative Optical Coherence Tomography Guided Ocular Surgeries: Critical Analysis of Clinical Role and Future Perspectives

      Intraoperative imaging of ocular tissues for diagnostic and therapeutic applications has gained immense admiration in recent years. The real time cross-sectional imaging, as well as three and four dimensional reconstruction abilities of intraoperative optical coherence tomography (iOCT), has enhanced our knowledge on many fronts in surgical maneuvers. In this review, we discuss the iOCT discovered constructive knowledge in the cornea, cataract, refractive, glaucoma, pediatric ocular, and various retinal conditions. The practical utility with decision modifying aspects along the specified ocular tissues and with respect to specific ocular entities have been narrated. Moreover, limitations and future directions have also been emphasized ...

      Intraoperative optical coherence tomography-guided subretinal cocktail injection in a case of ruptured retinal artery macro-aneurysm with multilevel bleed

      Submacular hemorrhage (SMH) following ruptured retinal artery macro aneurysm (RRAM) has better prognosis as compared to other etiologies. Timely intervention from as early as 24 h to less than 7 days is known to provide better visual outcomes in such cases. A variety of surgical techniques have been described in the treatment of RRAM. In this case report, we describe the advantages of intraoperative optical coherence tomography-guided sub-retinal injection of a cocktail mixture consisting of recombinant tissue plasminogen activator, bevacizumab, and air. Faster visual recovery with an immediate displacement of sub-macular bleed can be achieved with this technique in cases ...

      Clinical, ultrasonographic and optical coherence tomography correlation of optic nerve head cupping in glaucoma patients

      Purpose: To ascertain if ultrasound (USG) B-scan examination of the optic nerve head (ONH) can be a useful tool to diagnose and quantify glaucomatous cupping. Methods: A cross-sectional observational study of 48 eyes of 48 patients with clear ocular media and cup-disc ratio of (CDR) ≥0.6 were included. The disc was studied by + 90D examination, USG B-scan and ONH Optical coherence tomography (OCT) by three masked observers. Observer-1 assessed the clinical CDR, observer-2recordedopticcup diameter on USG B-scan and observer-3performed ONH OCT to note the software computed average CDR. Measurements of cupping obtained by these 3 methods were compared and ...

      Intraoperative assessment of corneal injuries using microscope-integrated optical coherence tomography

      A 2-year-old male child presented to the ocular emergency following penetrating injury with a metallic foreign body. Clinical examination revealed a nasal corneal perforation with iris tissue prolapse [ [Figure 1] , yellow arrow ]. To further delineate the extent of the corneal perforation and associated anterior segment changes, integrated optical coherence tomography (iOCT) was used. It showed corneal wound gaping for entire corneal thickness from the paracentral region to the periphery of the cornea. Within the gaping, prolapsing hyperreflective tissue was made out in continuity with the iris tissue onto the surface of the epithelium, suggestive of iris tissue [Figure 2] a ...

      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 ...
