Purpose To present the different clinical manifestations of rhino-orbital mucormycosis (ROM) co-infection in severe COVID-19 patients. Study design Prospective observational clinical study Methods Among 32,814 patients hospitalized with the diagnosis of COVID-19 between March 2020 and December 2020 in our center, eleven microbiologically confirmed ROM co-infection cases in severe COVID-19 patients were evaluated. Results There were nine men and two women with a mean age of 73.1 ± 7.7 years. Eight patients had uncontrolled type 2 diabetes with a mean diagnosis duration of 12.1 ± 4.4 years. All patients had COVID-19-associated acute respiratory distress syndrome and received corticosteroids. The mean time interval between COVID-19 diagnosis and ROM diagnosis was 14.4 ± 4.3 days. Seven patients (63.6%) had orbital apex syndrome, and four patients (36.4%) presented with orbital cellulitis. Endophthalmitis was detected in 54.5% of patients, and two of these patients developed retinoschisis. CT scan/MRI revealed sino-orbital involvement in all patients, and three of these had cerebral involvement at initial presentation. All patients received intravenous and retrobulbar liposomal amphotericin B and had undergone radical debridement of involved sinuses. Intravitreal liposomal amphotericin B injected in patients with endophthalmitis. Despite all measures, 63.6% of patients expired. Conclusions Severe COVID-19 is associated with a significant incidence of ROM with higher mortality rates due to immune dysregulation and the widespread use of steroids. Physicians should be aware of the possibility of this infection in patients with COVID-19. An aggressive multidisciplinary approach can help to reduce mortality.

Purpose: The coronavirus disease 2019 (COVID-19) spread rapidly worldwide, causing a severe outbreak. Because the disease is easily transmitted, face masks are a vital tool to slow the spread. The aim of this study is to investigate the impacts of face mask use on standard automated perimetry (SAP) results in glaucoma patients. Materials and Methods: All follow-up glaucoma patients who underwent SAP between May and October 2020 were enrolled in this study. In patients with low test reliability and/or visual field changes, SAP was repeated after repositioning and taping patients’ face masks. Results: A total of 127 patients (59 female and 68 male) with a mean age of 59.8±10.3 years were included in the study. While 101 patients (79.5%) wore surgical face masks, 26 patients (20.5%) wore cloth face masks. Low SAP reliability appeared in 23 patients (18.1%), and inferior visual field defects were present in 3 patients (2.4%). The main effects of poorly fitting face masks on SAP reliability were increased fixation losses and false-positive errors (for both, P=0.001). Low SAP reliability was significantly higher in patients wearing cloth face masks than in those wearing surgical face masks (47.8% vs. 9.9%; P=0.0001). The face mask–related fogging of eyeglasses before SAP is a strong predictor of fogging of the trial lenses–related low SAP reliability (odds ratio: 27, 95% confidence interval: 5.48-132.92, P=0.0001). In all repeated SAPs, the patients’ reliability parameters improved, and inferior visual field artifacts disappeared. Conclusions: Unsuitable face masks can cause either visual field artifacts, which may be interpreted as glaucoma progression or low test reliability. Taping the face masks’ upper edges is an effective technique to prevent visual field artifacts and obtain good test reliability.
PurposeTo report the therapeutic efficacy and results of an accidentally injected intralenticular sustained-release dexamethasone implant (Ozurdex) in a patient with macular edema secondary to central retinal vein occlusion at 14 months after injection.ObservationsWe present a 70-year-old female patient with central retinal vein occlusion who underwent an Ozurdex injection. Patient discontinued from the treatment period during the 14-month and there was no ophthalmologic examination of the patient. Detailed ophthalmological examination was performed. Ozurdex localization was determined by Pentacam rotating Scheimpflug System. The implant was accidentally injected into the crystalline lens. It did not cause a totally lens opacification but did result only in a posterior subcapsular cataract. The macular edema did not resolve, and the patient underwent phacoemulsification surgery.Conclusions and importanceOzurdex that totally located inside the crystallize lens may not have the therapeutic effects.
Purpose: To determine whether the corneal topographic parameter values, individual corneal layer thicknesses, and its endothelial layer morphology are different in patients with hemifacial spasm (HFS) than in the control contralateral eye. Methods: This study was designed as a prospective study. Among patients who applied to our hospital within the past 3-year period, those with HFS in one eye (study eyes) and a completely normal contralateral eye (control eyes) were included in this study. In addition to a complete ophthalmologic examination, all patients were scanned by the Pentacam Scheimpflug camera, and a corneal endothelium cell count was taken using a Topcon Specular Microscope. Also, the thickness of the corneal sublayers was measured on the central cornea with anterior segment module of spectral domain optical coherence tomography. Data entered using SPSS software were then evaluated by paired t test; P<0.05 value was considered statistically significant. Results: Twenty-eight patients (16 women and 12 men) were evaluated. Steep K, Kmax, and astigmatism values were significantly higher in the study eyes of patients with HFS than in the control eyes (P<0.05, for all). In addition, the total corneal thickness and corneal stromal thickness measurements in the study eyes were statistically significantly thinner than the control eyes (P=0.04 and P<0.001, respectively). Specular microscopy parameters were not statistically significant between the study eyes and control eyes (P>0.05, for all). Conclusion: Corneal stromal thinning suggests that chronic exposure to hypoxia may induce this effect through extracellular matrix remodeling and losses in collagen framework content in patients with HFS.
During corneal topography imaging, the Valsalva maneuver observed in patients with keratoconus does not typically cause any significant change in corneal morphology.
