Abstract
Mucormycosis is a rare but serious opportunistic fungal disease characterized by rhino-orbito-cerebral and pulmonary involvement. It is mainly seen in people with secondary immunosuppression, isolated vitamin A deficiency, measles, and AIDS patients. It showed a rise during the second wave of the COVID-19 epidemic in the spring of 2021 in India, especially in diabetic COVID-19 patients. Vitamin A deficiency is known to cause nutritional immunodeficiency and hence leading the way to increased opportunistic fungal, bacterial, and viral infections. In the eye, it causes keratitis, night blindness, xerophthalmia, conjunctivitis, Bitot spots, keratomalacia, and retinopathy. It also causes decreased tear secretion and deterioration of the anatomical/physiological defense barrier of the eye. The negative impact of vitamin A deficiency has been previously demonstrated in measles, AIDS, and COVID-19. We think that mucormycosis in COVID-19 might be rendered by vitamin A deficiency and that vitamin A supplementation may have preventive and therapeutic values against mucormycosis and other ocular symptoms associated with COVID-19. However, any vitamin A treatment regimen needs to be based on laboratory and clinical data and supervised by medical professionals.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is a rare sarcoma of the dermis. It is a malignant, locally aggressive, and infiltrative tumor with frequent recurrence. In this case, a 44-year-old woman presented with a 15-year history of a swelling in the medial canthus of the right eye that caused tearing. Imaging revealed a septated mass isodense to soft tissue that had eroded the medial wall of the orbit. Macroscopic examination showed an elastic, gray-brown, encapsulated, irregular mass measuring 45x35x22 mm. The surgical margins were positive, so adjuvant radiotherapy was started. The patient was followed for 2 years without recurrence. According to the literature, this mass is the largest orbital DFSP treated by globe-sparing primary resection.

Abstract
Objectives In Turkey, preventive medicine services are the responsibility of family physicians and vision screening is a key component of this responsibility. In this study, we aimed to investigate the approach of family physicians to vision screening in infants and children. Materials and Methods Data were collected using a 16-item questionnaire administered to 100 family physicians working in the center and provinces of Diyarbakır. Results The results indicated that 88 (88%) physicians declared knowing what the red reflex test was, while 12 physicians declared that they had never heard of it. Only 16 (16%) physicians performed the test routinely and 36 (36%) physicians performed it only in suspicious cases. Ten (10%) physicians indicated that they did not refer the patients to an ophthalmologist even though they did not perform the red reflex test. Moreover, 5 (5%) physicians did not have an ophthalmoscope and 12 (12%) physicians reported not knowing how to use an ophthalmoscope. Forty (40%) of the physicians measured preschool visual acuity at least once. Sixty-six (66%) physicians referred younger children who could not express their vision problems to an ophthalmologist. Four (4%) physicians declared that they would delay surgery in children with strabismus until they were old enough for surgery. Ninety-three (93%) physicians suggested that educational seminars about vision screening would be beneficial. Conclusion Educational seminars about vision screening may have favorable outcomes. The medical devices in family medicine centers should be improved. Vision screening can be added to the negative performance-based compensation system in order to increase physicians’ attention to vision screening. To implement detailed eye screening programs like those in developed countries, an infrastructure should be established for this screening program.

Abstract
PURPOSE To measure the vascular density (VD) and foveal avascular zone (FAZ) area in patients with Behçet's disease (BD) obtained by optical coherence tomography angiography (OCTA). METHODS VD and FAZ area in the deep and superficial retinal vascular networks were measured in all eyes. RESULTS Thirty BD and 31 control subjects were included in the study. The mean overall VD measured in the entire scan was lower in BD compared with control group in both the superficial (49.52 ± 6.54 vs 53.57 ± 2.87%, respectively; p = 0.003) and deep (53.44 ± 7.44 vs 58.41 ± 3.01%, respectively; p = 0.002) areas. The FAZ in the BD group was significantly increased at the level of the superficial (0.52 ± 0.67 vs 0.28 ± 0.1 mm2, respectively; p = 0.05) and deep (0.91 ± 1.25 vs 0.39 ± 0.14 mm2, respectively; p = 0.024) areas compared with those of the control group. The deep and the superficial FAZ areas were positively correlated with disease duration and negatively with VA. CONCLUSION In the patients with BD, OCTA showed decreased VD in both the superficial and deep retinal vascular networks. Besides, the VA was correlated with the VD and FAZ.

Abstract
PURPOSE To compare the retina ganglion cell complex (GCC) layer and peripapillary nerve fibre layer thickness (pRNFL) in patients with prediabetes and healthy subjects analysed by spectral domain optical coherence tomography (SD-OCT). METHODS This cross-sectional and comparative study included prediabetic patients and healthy subjects. All participants underwent SD-OCT measurement of pRNFL thickness, and GCC thickness. RESULTS A total of 30 eyes of the 30 patients with prediabetes and 30 eyes of 30 controls were included. The overall calculated pRNFL thicknesses were similar between the prediabetic and control subjects. The GCC thickness was significantly lower in all quadrants of the inner macula, and outer nasal quadrant in the prediabetes group when compared to the control group. CONCLUSION Our study demonstrated that inner macular GCC thickness was significantly thinner in prediabetic subjects. As a result neurodegeneration may play role in the thinning of GCC.

Abstract
The purpose of this study is to examine the capability of photoacoustic (PA) imaging (PAI) in assessing the unique molecular and architectural features in ocular tumors. A real-time PA and ultrasonography (US) parallel imaging system based on a research US platform was developed to examine retinoblastoma in mice in vivo and human retinoblastoma and uveal melanoma ex vivo. PA signals were generated by optical illumination at 720, 750, 800, 850, 900 and 950 nm delivered through a fiber optical bundle. The optical absorption spectra of the tumors were derived from the PA images. The optical absorption spectrum of each tumor was quantified by fitting to a polynomial model. The microscopic architectures of the tumors were quantified by frequency domain analysis of the PA signals. Both the optical spectral and architectural features agree with the histological findings of the tumors. The mouse and human retinoblastoma showed comparable total optical absorption spectra at a correlation of 0.95 (p<0.005). The quantitative PAI features of human retinoblastoma and uveal melanoma have shown statistically significant difference in two tailed t-tests (p<0.05). Fully compatible with the concurrent procedures, PAI could be a potential tool complementary to other diagnostic modalities for characterizing intraocular tumors.

Abstract
PURPOSE To evaluate the knowledge and behaviors of ophthalmologists in Turkey concerning micronutrition support in patients with age related macular degeneration (ARMD). METHODS This study involved 1,845 ophthalmologists. A scientific poll was sent to all participants by email. The survey covered the following: demographic features, subspecialty knowledge about micronutrition preference for prescribing micronutrition to age related macular degeneration patients, and the reason for this preference. If a participant indicated that he or she prescribed micronutrition, the participant was also asked to indicate the source of the treatment and supplemental treatments. RESULTS Of 1,845 ophthalmologists, 249 responded to the survey. Of the respondents, 9% (22) never, 43% (107) sometimes, 37% (92) frequently, and 11% (27) always used micronutrition. The most frequent prescribing subgroup was general ophthalmology (22%), followed by the retina-uvea subspecialty (13.9%). The micronutrition prescribing ratio was 54.8% in retina-uvea specialists when the "frequent" and "always" responses were combined. There was no statistically significant difference between subgroups with respect to prescribing micronutrition. Among the ophthalmologists prescribing micronutrition, 57.1% of them did not use the Age-Related Eye Disease Study-1 (AREDS) criteria, and only 31.3% prescribe micronutrition according to AREDS criteria. The results for the general ophthalmologist and retina-uvea specialist subgroups were similar, 56.3% vs 20.2%, and 54.1% vs 36.1%, respectively. Micronutrition was not recommended for the following reasons: expensive (55.4%), low patient expectancy (40%), no effect (30%), and low patient drug compliance (25.4%). Moreover, 55.2% of the clinicians recommended physical activities, dietary changes, and smoking cessation; 7.3% did not recommend these behavioral changes. CONCLUSION This survey demonstrated that micronutrition preference in age related macular degeneration was low in ophthalmologists in Turkey. Additionally, retina specialists have a lower rate of prescribing micronutrition. Micronutrition support and behavior such as smoking cessation, dietary changes, etc. should be recommended more often to patients with age related macular degeneration.

Abstract
BACKGROUND The aim of this study is to investigate and compare the serum levels of various cytokines in patients with Behçet's Disease and healthy controls. METHODS Thirty-five patients with Behçet's disease and 29 age and sex-matched healthy controls were included in the study. The patients were separated into groups with active and inactive disease. Serum IL-2, IL-6, IL-8, IL-10, IL-17A, and IFN-γ levels were determined using the enzyme-linked immunosorbent assay method. Cytokine levels of the two patient groups and healthy controls were compared using SPSS 15.0. RESULTS Ten patients with active disease and 25 patients with inactive disease were present. Serum IL-8 levels of active BD patients were higher compared to inactive patients (P = 0.048) and healthy controls (P = 0.02). IL-8 levels were correlated with the duration of symptoms (r = 0.490, P = 0.003) and time passed since diagnosis (r = 0.579, P ˂ 0.001). CONCLUSION Behçet's disease involves complex interactions of cells of the immune system, mainly T lymphocytes and neutrophils. Further studies on the cytokine profile in Behçet's disease will aid in elucidation of its pathogenesis.
