ABSTRACT
Purpose: To study the clinical profile and magnetic resonance imaging (MRI) features in patients of COVID?19?associated rhino?orbital?cerebral mucormycosis (CA?ROCM) with orbital involvement and perform a clinicoradiological correlation. Methods: A cross?sectional study was performed at a tertiary care center in north India from May 2021 to June 2021. Consecutive patients with clinical, nasal endoscopic, and/or microbiological evidence of CA?ROCM underwent MRI of paranasal sinuses, orbit, and brain as per the study protocol. Orbital MRI findings were studied in detail and were correlated with clinical signs. Results: Two hundred and seventy patients were studied. The mean age was 48.4 (± 16.82) years. A male predilection was noted (male:female = 1.77). Orbital involvement was seen in 146 (54%) patients on clinical evaluation and in 184 (68%) patients on MRI. Unilateral orbital involvement was more common (134; 92%). The most common presenting symptom was periorbital and/or facial pain (141; 52.2%) and the most common clinical sign was periorbital edema (116; 43%). The most common MRI finding was suggestive of orbital cellulitis (160; 59%). Orbital compartment syndrome was found in 17 (6.3%) patients. The inter?rater agreement between clinical and radiological assessments to detect the involvement of infraorbital nerve and frontal nerve was found to be 85.56%, (? 0.621) and 93.70% (? 0.776), respectively. The diagnostic accuracy, sensitivity, and specificity of MRI to detect medial orbital wall defect were found to be 87.9%, 65%, and 97%, respectively. Conclusion: Orbital imaging features of a cohort of ROCM patients have been presented with clinicoradiological correlation.
ABSTRACT
Purpose: The purpose of this study was to analyze the clinical profile of medicolegal cases (MLCs) presenting to the eye casualty in a tertiary care hospital. Materials and Methods: Retrospective review of records. The cases were grouped according to the Ocular Trauma Classification Group classification system. Results: Out of 188 MLCs, 164 (87.2%) were male. Mean age (±standard deviation) was 31.6 (±12.7) years. Age ranged from 7 to 75 years. Twenty‑six (13.8%) patients had bilateral involvement. The fist was the most common mode of injury, which was seen in 109 (58%) cases. A total of 27 (14.3%) patients had associated extraocular injury. No evidence of ocular or orbital trauma (malingering) could be found in 13 (7%) patients. Mechanical trauma was present in 169 (90%) patients with injury to globe in 129 (69%) patients and injury to lid or orbit without damage to the globe in 40 (21%) patients. Chemical injury was observed in 6 (3%) patients. Closed globe injury (CGI) was seen in 116 eyes and open globe injury (OGI) was noted in 29 eyes. The most common type of injury, zone, pupil, and grade of injury in CGI were Type A or contusion (79%), Zone I (72%), Pupil B (absence of relative afferent pupillary defect) in 95%, and Grade A [visual acuity (VA) ≥20/40] in 68% of the eyes, respectively. The most common type of injury, zone, pupil, and grade of injury in OGI were Type B or penetrating (48%), Zone II (38%), Pupil B (59%), and Grade D (VA 4/200‑light perception) (42%), respectively. Conclusions: The most common form and mode of ocular injury in MLC were closed globe injury and fist, respectively. The most common type of injury in CGI and OGI was contusion and penetrating injury, respectively.
