ABSTRACT
Purpose: To analyze the correlation between the mean retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness with axial length and refractive errors among children aged 5–15 years. Methods: This cross?sectional, observational study was done on 130 eyes of 65 consecutive subjects with refractive errors. The patients were evaluated for RNFL thickness and macular GCL thickness using spectral domain? optical coherence tomography. Results: One hundred and thirty eyes of 65 subjects aged between 5 and 15 years were divided into three groups based on their spherical equivalent in diopters (D). The children with a spherical equivalent of ??0.50 D were considered myopic, ??0.5 to ?+0.5 D were considered emmetropic, and ?+0.50 D were considered hypermetropic. RNFL thickness and GCL thickness were correlated with age, gender, spherical equivalent, and axial length. The mean global RNFL thickness was 104.58 ?m ± 7.567. Conclusion: There exists a negative correlation between RNFL thickness and macular GCL thickness with increasing severity of myopia and increase in axial length, and the possible reason could be stretching of the sclera, which further leads to stretching of the retina, resulting in thinner RNFL and macular GCL thickness
ABSTRACT
Purpose: To report the clinico?demographic profile of rhino?orbito?cerebral mucormycosis (ROCM) in patients during the “second wave” of the COVID?19 pandemic in eastern India, and their ophthalmic manifestations at presentation to our tertiary institute. Methods: Cross?sectional study amongst patients presenting to our center based on their hospital records. Demographic information, history related to COVID?19, records of detailed ocular examination, and microbiological, radiological, and histopathological investigation were entered into an online worksheet and analyzed using SPSS 26.0. Results: A total of 219 patients with ROCM were treated from May to September 2021, and 110 of these had ocular manifestations at presentation (50.2%). The age of patients ranged from 22 to 83 years and the mean ± standard deviation (SD) age was 49.9 ± 12.9 years. Ninety (81.8%) patients had been diagnosed with diabetes mellitus, 31 (34%) had hypertension, and 10 had other comorbidities. The duration between the onset of COVID?19 and mucormycosis symptoms was 0 to 60 days with a mean ± SD interval of 20.9 ± 12.6 days. Fifty?six (50.9%) patients had a history of steroid use. Unrelenting ocular or facial pain was the most common presenting symptom, ptosis was the most common anterior segment manifestation, and ophthalmic artery occlusion was the most common posterior segment manifestation. Conclusion: Our data from eastern India reinforces the relationship between COVID?19, diabetes, corticosteroid use, and ROCM. Knowledge of various presenting anterior and posterior segment manifestations of the disease as described in the present study will guide clinicians to recognize the disease early and make every effort to prevent complications.
