    1. Intralenticular changes in eyes with mature senile cataract on modified posterior segment optical coherence tomography

      Intralenticular changes in eyes with mature senile cataract on modified posterior segment optical coherence tomography

      Purpose: To study the morphological changes within mature senile cataracts on modified posterior segment optical coherence tomography (OCT). Methods: A cross-sectional observational study recruiting patients of mature cataracts admitted for elective cataract surgery in tertiary eye care. A modified OCT imaging of the lens was done and lenticular findings were noted by a single observer. Corresponding slit-lamp biomicroscopic findings and intraoperative experiences were also noted by a second observer and respective surgeons. Results: Forty-four eyes of 44 patients were included. The mean age of patients was 65 ± 5.7 years. The intralenticular findings were uniform in groups of eyes, and ...

    2. Cyclodialysis Cleft in a Case of Open-globe Injury and Role of Swept-source Anterior Segment Optical Coherence Tomography in Diagnosis

      Cyclodialysis Cleft in a Case of Open-globe Injury and Role of Swept-source Anterior Segment Optical Coherence Tomography in Diagnosis

      SIGNIFICANCE Cyclodialysis clefts can potentially develop secondary to open globe injury. The swept-source anterior segment optical coherence tomography (SS-AS-OCT) may be a valuable diagnostic tool for the identification and estimation of the circumferential extent of cyclodialysis clefts. It could be considered an alternative when ultrasound biomicroscopy cannot be performed successfully. PURPOSE The purpose of this study was to report a case of open-globe injury associated with cyclodialysis cleft and the utility of SS-AS-OCT in its diagnosis. CASE REPORT A 12-year-old boy presented to the clinic because of penetrating ocular trauma to his left eye with a projectile stone. He was ...

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

      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 ...

    4. COMPARATIVE EVALUATION OF ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY, ULTRASOUND BIOMICROSCOPY, AND INTRAOCULAR PRESSURE CHANGES AFTER PANRETINAL PHOTOCOAGULATION BY PASCAL AND CONVENTIONAL LASER

      COMPARATIVE EVALUATION OF ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY, ULTRASOUND BIOMICROSCOPY, AND INTRAOCULAR PRESSURE CHANGES AFTER PANRETINAL PHOTOCOAGULATION BY PASCAL AND CONVENTIONAL LASER

      Purpose: To compare intraocular pressure, anterior segment optical coherence tomography, and ultrasound biomicroscopy parameters over 3 months after panretinal photocoagulation (PRP) for proliferative diabetic retinopathy after 1 of 2 sittings by conventional laser (half PRP) and a single sitting of Pattern Scan Laser (PASCAL) PRP. Methods: This was a prospective, randomized, interventional study. All tests were performed at baseline, and at 1, 6, and 24 hours, and 1, 4, 8, and 12 weeks after PRP. Results: The intraocular pressure at 1 hour and 6 hours after PRP was significantly raised in both groups. Mean intraocular pressure was 21.17 ± 4 ...
