RESUMEN
We report an 84-year-old female patient who presented to our clinic with a complaint of low vision in her right eye. She described an occasional foreign body-like object around the pupil area. She had a history of extracapsular cataract surgery without an intraocular lens implantation 20 years ago. The patient underwent surgery to remove the foreign body-like object after conducting necessary investigations before surgery. The histopathological features of the specimen were consistent with a Soemmering ring. However, a Soemmering ring does not usually reduce vision unless it is dislocated, as in this case. We report this unusual case to show that ophthalmologists can encounter unexpected cases that present with complications as a result of previous cataract surgery after a lengthy period of time.

PURPOSE: This study aimed to investigate the effects of severe COVID-19 infection on the corneal endothelium via in vivo specular microscopy. METHODS: This was an observational, prospective, and controlled study including 56 eyes of 56 severe COVID-19 patients, compared to after-recovery and 56 eyes of 56 age- and gender-matched healthy controls. RESULTS: Endothelial cell density was lower in the active disease period compared to healthy controls (p = .001) and decreased even more after recovery (p < .0001). After recovery, the average cell area and coefficient of variation were higher compared to the active disease period (p < .0001 and p = .008, respectively) and the healthy controls (for both, p < .0001), whereas hexagonality was lower (p < .0001). Central corneal thickness increased in the active disease period compared to after recovery (p < .0001) and healthy controls (p = .002). CONCLUSIONS: These results may be due to direct host-virus interaction or linked to immune dysregulation, subclinical corneal endotheliitis, or still yet a viral-mediated inflammation.
RESUMEN
PURPOSE: This study aims to present a family with two children with MSS who presented with different ophthalmic features. We also aim to review MSS patients' ocular manifestations to provide a basis for future clinical trials and improve MSS patients' ophthalmologic care. CASE DESCRIPTION: Both patients presented with global developmental delay, microcephaly, cerebellar ataxia, and myopathy. The older sibling had developed bilateral cataracts at the age of six. Her 2 years younger sister interestingly showed bilateral hyperopic refractive error without cataracts yet. Mendeliome sequencing unraveled a novel homozygous frameshift mutation in the SIL1 gene (SIL1, NM_022464.5, c.1042dupG, p.E348Gfs*4), causing MSS. A systematic literature review revealed that cataracts appear in 96% of MSS cases with a mean onset at 3.2 years. Additional frequent ocular features were strabismus (51.6%) and nystagmus (45.2%). CONCLUSION: SIL1-related MSS is associated with marked clinical variability. Cataracts can develop later than neuromuscular features and cognitive signs. Since cataract is a relatively late finding, patients may refer to ophthalmologists for other reasons such as refractive errors, strabismus, or nystagmus. Molecular genetic testing for SIL1 is essential to facilitate early diagnosis in patients with suspected MSS.

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: To compare retinal and choroidal thickness in patients with Behçet's disease with and without ocular involvement as well as to evaluate the correlation between erythrocyte sedimentation rate and choroidal thickness among patients with Behçet's disease. METHODS: This was a prospective interventional study investigating erythrocyte sedimentation as well as choroidal and retinal thickness among patients with Behçet's disease. Patients who were diagnosed based on The International Criteria for Behçet's Disease with (Group A) or without (Group B) ocular involvement and a matched control group (Group C) participated in the study. Optical coherence tomography measurements and blood tests were performed on the same day. Retinal and choroidal thickness were measured using spectral-domain optical coherence tomography (Spectralis, Heidelberg Engineering, Heidelberg, Germany), and central macular thickness, central subfoveal choroidal thickness, and retinal nerve fiber layer thickness were measured using optical coherence tomography. RESULTS: Average erythrocyte sedimenta-tion values were 9.89 mm/h in Group A, 16.21 mm/h in Group B, and 3.89 mm/h in Group C; average central subfoveal choroidal thickness values were 350.66, 331.74, and 325.95 mm, respectively. Average central macular thickness and retinal nerve fiber layer thickness values of patients in Groups A, B and C were 226.39 and 225.97mm; 234.11 and 92.00 mm; and 97.58 and 99.84 mm, respectively. No significant difference was seen between Group A and B patients in central subfoveal choroidal thickness, central macular thickness, or retinal nerve fiber layer thickness values. Central macular thickness was statistically significantly thinner in Groups A and B than in Group C (p=0.016). Group A had thinning in the nasal quadrant of the retinal and general retinal nerve fiber layers when compared with those in Group C (p=0.010 and 0.041, respectively). A connection could not be established between the erythrocyte sedimentation, central subfoveal cho-roidal thickness, central macular thickness, and retinal nerve fiber layer thickness in the patients with Behçet's disease. CONCLUSION: The erythrocyte sedimentation rate is typically used to test for activation of Behçet's disease and assess treatment response. In our study, we could not establish a connection between the erythrocyte sedimentation rate and central subfoveal choroidal thickness, central macular thickness, and retinal nerve fiber layer thickness in patients with systematically active Behçet's disease without ocular involvement.

PURPOSE: Evaluation of the nerve fiber thicknesses of the macula, choroid, and retina using the apnea-hypopnea index in individuals with obstructive sleep apnea syndrome (OSAS) without systemic components. METHODS: Prospective, controlled study. The central macular, choroidal, and retinal nerve fiber layer (RNFL) thicknesses were evaluated using enhanced depth imaging-spectral domain optical coherence tomography in individuals with OSAS. In people with severe OSAS who had received treatment, posterior ocular structures were examined over 3 months (4th and 12th weeks), and changes were evaluated. Only the right eyes of the participants were evaluated in the study. RESULTS: A total of 72 people were involved in the study, with 18 in the control group and 19 with mild, 16 with moderate, and 19 with severe OSAS. No significant difference was found among the groups in terms of demographic measures. No significant differences were found among the groups in terms of the measures of central macular, central subfoveal choroidal (CSCT), temporal choroidal, nasal choroidal, and RNFL thicknesses. In severe OSAS cases in which treatment was administered, although subjective clinical recovery was observed, statistically significant thinning was detected during the 3-month follow-up period in the CSCT, general RNFL, as well as in the inferior and superior nasal quadrants, and temporal superior quadrant (p=0.005, p=0.009, p=0.039, p=0.003, and p=0.02, respectively). CONCLUSION: In the group with severe OSAS, thinning in some posterior ocular tissues was observed. Although patients with severe OSAS may experience clinical recovery, we recommend that they would be followed up in terms of ocular ischemic injury.

PURPOSE: To obtain aqueous humor and tear fluid samples during cataract surgery of the hepatitis C virus (HCV)-antibody-positive patients in order to analyze them for HCV RNA and compare these measurements with serum HCV RNA levels. METHODS: Twenty-nine anti-HCV-positive patients were included this study. HCV RNA viral load levels were determined by commercial real-time polymerase chain reaction system. Antibodies to HCV were screened with the enzyme-linked immunosorbent assay (ELISA) using anti-HCV test kit. RESULTS: Log10 HCV RNA levels were found to be 6.00 ± 1.06 IU/mL in serum, 2.76 ± 0.36 IU/mL in the aqueous humor, and 1.91 ± 0.93 IU/mL in tear fluid. No correlation was detected between samples for HCV RNA positivity (p = .390, κ = .102). We have observed that, viral RNA was detected in the aqueous humor, while not in serum in one case, whereas viral RNA was detected in tear fluid but not in serum in another case. CONCLUSIONS: Although viral load detected in aqueous humor and tear fluid samples was considerably lower compared to the serum samples, it can still be important in terms of infectivity.

Aim. To assess the effects of mydriatics commonly used in clinical practice on choroidal thickness and anterior chamber change. Methods. This was a prospective, randomized, controlled, double-blinded study including a single eye of the participants. The subjects were assigned into 4 groups to receive tropicamide 1%, phenylephrine 2.5%, cyclopentolate 1%, and artificial tears. At the baseline, anterior chamber parameters were assessed using a Pentacam Scheimpflug camera system, and choroidal thickness (CT) was measured using a spectral-domain OCT with Enhanced Depth Imaging (EDI) modality. All measurements were repeated again after drug administration. Results. Increases in pupil diameter, volume, and depth of anterior chamber were found to be significant (p = 0.000, p = 0.000, and p = 0.000, resp.), while decreases in the choroidal thickness were found to be significant in subjects receiving mydriatics (p < 0.05). Conclusions. The study has shown that while cyclopentolate, tropicamide, and phenylephrine cause a decrease in choroidal thickness, they also lead to an increase in the volume and depth of anterior chamber. However, no correlation was detected between anterior chamber parameters and choroidal changes after drug administration. These findings suggest that the mydriatics may affect the choroidal thickness regardless of anterior chamber parameters. This study was registered with trial registration number 2014/357.
RESUMEN
PURPOSE: Optic coherence tomography (OCT) evaluation of the choroid, retina, and retinal nerve fiber layer after uncomplicated yttrium-aluminum-garnet (YAG) laser capsulotomy. METHODS: OCT analysis of retinal and choroidal structures was performed in 28 eyes of 28 patients following routine examinations before and 24 h, 72 h, 2 weeks, 4 weeks, and 12 weeks after YAG laser capsulotomy. Data were analyzed using the SPSS software. RESULTS: Data collected before YAG capsulotomy and at the above mentioned follow-up visits are summarized as follows. Mean central subfoveal choroidal thickness before YAG capsulotomy was 275.85 ± 74.78 µm; it was 278.46 ± 83.46 µm, 283.39 ± 82.84 µm, 280.00 ± 77.16 µm, 278.37 ± 76.95 µm, and 278.67 ± 76.20 µm after YAG capsulotomy, respectively. Central macular thickness was 272.14 ± 25.76 µm before YAG capsulotomy; it was 266.53 ± 26.47 µm, 269.14 ± 27.20 µm, 272.17 ± 26.97 µm, 270.91 ± 26.79 µm, and 273 ± 26.63 µm after YAG capsulotomy, respectively. Mean retinal nerve fiber layer thickness before YAG was 99.89 ± 7.61 µm; it was 98.50 ± 8.62 µm, 98.14 ± 8.69 µm, 99.60 ± 8.39 µm, 99.60 ± 8.39 µm, and 99.60 ± 8.35 µm after YAG capsulotomy, respectively. No observed change was statistically significant. No significant changes were observed with regard to mean intraocular pressure. CONCLUSIONS: After YAG laser capsulotomy, no statistically significant changes were found in choroidal, retinal, and optical nerve fiber layer thicknesses, although slight thickness changes in these structures were observed, particularly during the first days.

AIM: To evaluate the effects of moxifloxacin exposure on the conjunctival flora and antibiotic resistance profile following repeated intravitreal injections. METHODS: Seventy-two eyes of 36 patients [36 eyes in control group, 36 eyes in intravitreal injection (IVI) group] were enrolled in the study. All the eyes had at least one IVI and had diabetic macular edema (DME) or age-related macular degeneration (ARMD). Moxifloxacin was prescribed to all the patients four times a day for five days following injection. Conjunctival cultures were obtained from the lower fornix via standardized technique with every possible effort made to minimize contamination from the lids, lashes, or skin. Before the application of any ophthalmic medication, conjunctival cultures were obtained from both eyes using sterile cotton culture. An automated microbiology system was used to identify the growing bacteria and determine antibiotic sensitivity. RESULTS: The bacterial cultures were isolated from 72 eyes of 36 patients, sixteen of whom patients (44.4%) were male and twenty (55.6%) were female. Average age was 68.4±9.0 (range 50-86). The average number of injections before taking cultures was 3.1+1.0. Forty-eight (66.7%) of 72 eyes had at least one significant organism. There was no bacterial growth in 8 (20.5%) of IVI eyes and in 16 (44.4%) of control eyes (P=0.03). Of the bacteria isolated from culture, 53.8% of coagulase negative staphylococci (CoNS) in IVI eyes and 47.2% CoNS in control eyes. This difference between IVI eyes and control eyes about bacteria isolated from culture was not statistically significant (P=0.2). Eleven of 25 bacteria (44.0%) isolated from IVI eyes and 11 (57.9%) of 19 bacteria isolated from control eyes were resistant to oxacillin. The difference in frequency of moxifloxacine resistance between two groups was not statistically significant (12.0% in IVI eyes and 21.1% in control eyes) (P=0.44). There were no cases of resistance to vancomycin, teicoplanin and linezolid. CONCLUSION: There was no difference in species of bacteria isolated from cultures, or in the frequency of resistance to antibiotics between eyes that had recurrent IVI followed by moxifloxacin exposure compared with control eyes. However, the number of eyes that had bacterial growth was higher in IVI group than in the control group.
RESUMEN
Purpose. To assess the macular, choroid, and peripapillary nerve fiber layer thickness (RNFL) in Behçet's disease (BD) patients with and without ocular involvement by means of optical coherence tomography (OCT) and compare these findings with healthy controls. Design. Eighty patients with BD and 40 healthy controls who were followed up at the Uveitis and Retina Clinic of the Kayseri Research and Education Hospital in Turkey were enrolled in this prospective study. Subjects and Controls. The patients with BD were divided into two groups according to the presence of ocular involvement. Group 1 consisted of 40 eyes of 40 patients with ocular involvement and group 2 consisted of 40 eyes of 40 patients without ocular involvement. Methods. All of the patients and controls underwent macular, choroid, and peripapillary nerve fiber layer thickness analysis with Spectralis domain OCT (Spectralis OCT Heidelberg Engineering, Dossenheim, Germany). Main Outcome Measures. The differences in macular, choroid, and peripapillary nerve fiber layer thicknesses between groups were analyzed statistically. Results. Macular thickness was thinner in patients with BD than in the control group; this result was statistically significant (P = 0.05). There was no statistically significant difference in thickness between RNFL analysis of the patients with BD and control subjects. However, the BD patients with ocular involvement had statistically significant thinning in RNFL compared with BD patients without ocular involvement. Although the choroid was thicker in patients with BD than in the control group, it did not reach a statistically significant level (P = 0.382). Conclusions. BD with ocular involvement may be associated with decreased macular and RNFL thickness measured with spectral-domain OCT.

RESUMO Objetivos: Comparar a espessura da retina e da coroide em pacientes com doença de Behçet, com e sem acometimento ocular e avaliar a correlação entre a taxa de sedimentação de eritrócitos e a espessura da coroide em pacientes com doença de Behçet. Métodos: Estudo prospectivo intervencional que investigou a sedimentação de eritrócitos, espessura de coroide e da retina em pacientes com doença de Behçet. Os pacientes que foram diagnosticados com base nos Critérios Internacionais para a Doença de Behçet com (Grupo A) ou sem (Grupo B) envolvimento ocular e um grupo controle correspondente (Grupo C) participaram do estudo. Medidas de tomografia de coerência óptica e exames de sangue foram realizados no mesmo dia. As espessuras da retina e da coroide foram medidas utilizando tomografia de coerência óptica de domínio espectral (Spectralis, Heidelberg Engineering, Hidelberg, Germany) e a espessura macular central, a espessura coroidal subfoveal central e a espessura da camada de fibra nervosa da retina foram medidas usando tomografia de coerência óptica. Resultados: Os valores médios de sedimentação de eritrócitos foram de 9,89 mm/h no Grupo A, 16,21 mm/h no Grupo B e 3,89 mm/h no Grupo C; os valores médios da espessura da coroide subfoveal central foram 350,66, 331,74 e 325,95 mm respectivamente. Os valores médios da espessura macular central e da espessura da camada de fibra nervosa da retina dos pacientes nos grupos A, B e C foram de 226,39, 225,97, 234,11 mm e 92,00, 97,58, 99,84 mm respectivamente. Não houve diferença significativa entre pacientes do Grupo A e B na espessura da coroide subfoveal central, espessura macular central ou valores da espessura da camada de fibra nervosa da retina. A espessura macular central foi estatisticamente significativamente mais fina nos Grupos A e B do que no Grupo C (p=0,016). O Grupo A apresentou afinamento na porção nasal das camadas retiniana e geral da fibra nervosa da retina quando comparado com o Grupo C (p=0,010, p=0,041, respectivamente). Não foi possível estabelecer uma conexão entre a sedimentação dos eritrócitos, a espessura subfoveal central da coroide, a espessura macular central e espessura da camada de fibras nervosas da retina nos pacientes com doença de Behçet. Conclusão: A taxa de sedimentação de eritrócitos é comumente utilizada para testar a ativação da doença de Behçet e avaliar a resposta ao tratamento. Em nosso estudo, não foi possível estabelecer uma conexão entre a taxa de sedimentação de eritrócitos e a espessura da coroide subfoveal central, espessura macular central e espessura da camada de fibras nervosas da retina em pacientes com doença de Behçet sistematicamente ativa sem envolvimento ocular.

ABSTRACT Purpose: Evaluation of the nerve fiber thicknesses of the macula, choroid, and retina using the apnea-hypopnea index in individuals with obstructive sleep apnea syndrome (OSAS) without systemic components. Methods: Prospective, controlled study. The central macular, choroidal, and retinal nerve fiber layer (RNFL) thicknesses were evaluated using enhanced depth imaging-spectral domain optical coherence tomography in individuals with OSAS. In people with severe OSAS who had received treatment, posterior ocular structures were examined over 3 months (4th and 12th weeks), and changes were evaluated. Only the right eyes of the participants were evaluated in the study. Results: A total of 72 people were involved in the study, with 18 in the control group and 19 with mild, 16 with moderate, and 19 with severe OSAS. No significant difference was found among the groups in terms of demographic measures. No significant differences were found among the groups in terms of the measures of central macular, central subfoveal choroidal (CSCT), temporal choroidal, nasal choroidal, and RNFL thicknesses. In severe OSAS cases in which treatment was administered, although subjective clinical recovery was observed, statistically significant thinning was detected during the 3-month follow-up period in the CSCT, general RNFL, as well as in the inferior and superior nasal quadrants, and temporal superior quadrant (p=0.005, p=0.009, p=0.039, p=0.003, and p=0.02, respectively). Conclusion: In the group with severe OSAS, thinning in some posterior ocular tissues was observed. Although patients with severe OSAS may experience clinical recovery, we recommend that they would be followed up in terms of ocular ischemic injury.
RESUMO Objetivo: Avaliação de espessuras das fibras nervosas da mácula, coroide e da retina de acordo com os índices de apnéia e hipopnéia (AHI) em indivíduos com síndrome da apneia obstrutiva do sono (OSAS), sem componentes sistêmicos. Métodos: Estudo prospectivo, controlado. As espessuras centrais maculares, da coroide e da camada de fibras nervosas da retina foram avaliadas tomografia de coerência óptica de domínio espectral de profundidade aprimorada em indivíduos com síndrome da apneia obstrutiva do sono. Em pessoas com OSAS grave a quem foi aplicado o tratamento, estruturas oculares posteriores foram examinados por três meses (4ª e 12ª semanas) e as alterações foram avaliadas. Apenas os olhos direitos dos participantes foram envolvidos no estudo. Resultados: 72 pessoas foram envolvidas no estudo, 18 no grupo controle e, 19 com OSAS leve, 16 com OSAS moderada e 19 com OSAS grave. Não houve diferença significativa entre os grupos em relação às medidas demográficas. Não houve diferenças significativas estavam presentes entre os grupos em termos de medidas de espessura macular central (CMT), espessura subfoveal central da coroide (CSCT), espessura da coroide temporal (TCT), espessura da coroide nasal (NCT) e, a camada de fibras nervosas da retina (RNFL). Em casos de OSAS graves onde o tratamento foi aplicado, apesar de ter sido observada recuperação clínica subjetiva, detectou-se afinamento estatisticamente significativo durante os três meses de acompanhamento, em CSCT, RNFL geral, quadrantes nasais inferior e superior, e quadrante temporal superior (p=0,005, p=0,009, p=0,039, p=0,003, p=0,02). Conclusão: No grupo com OSAS grave, foi observado afinamento em algumas áreas posteriores dos tecidos oculares. Embora os pacientes com OSAS grave possam apresentar recuperação clínica, recomendamos que eles sejam seguidos em termos de lesão isquêmica ocular.

Central macular thickness was 272.14 ± 25.76 µm before YAG capsulotomy; it was 266.53 ± 26.47 µm, 269.14 ± 27.20 µm, 272.17 ± 26.97 µm, 270.91 ± 26.79 µm, and 273 ± 26.63 µm after YAG capsulotomy, respectively. Mean retinal nerve fiber layer thickness before YAG was 99.89 ± 7.61 µm; it was 98.50 ± 8.62 µm, 98.14 ± 8.69 µm, 99.60 ± 8.39 µm, 99.60 ± 8.39 µm, and 99.60 ± 8.35 µm after YAG capsulotomy, respectively. No observed change was statistically significant. No significant changes were observed with regard to mean intraocular pressure. Conclusions: After YAG laser capsulotomy, no statistically significant changes were found in choroidal, retinal, and optical nerve fiber layer thicknesses, although slight thickness changes in these structures were observed, particularly during the first days.
RESUMO Objetivo: Avaliação da coroide, retina e a camada de fibras nervosas da retina por meio de tomografia de coerência óptica (OCT) após capsulotomia por YAG laser não complicada. Método: Vinte e oito olhos de 28 pacientes foram incluídos neste estudo. Estruturas da retina e coroide foram analisados usando ACT nos exames de rotina antes da capsulotomia posterior por YAG laser e 24 horas, 72 horas, 2 semanas, 4 semanas e 12 semanas após YAG. Os resultados foram avaliados através do programa SPSS. Resultados: Os resultados deste estudo, pré YAG e às visitas de acompanhamento acima, podem ser resumidos da seguinte forma. A espessura média de coroide subfoveal central antes do YAG foi 275,85 ± 74,78 m; após YAG foi 278,46 ± 83,46 µm, 283,39 ± 82,84 µm, 280,00 ± 77,16 µm, 278,37 ± 76,95 µm, e 278,67 ± 76,20 µm, respectivamente. A espessura macular central foi 272,14 ± 25,76 mm antes YAG; e 266,53 ± 26,47 µm, 269,14 ± 27,20 µm, 272,17 ± 26,97 µm, 270,91 ± 26,79 µm, e 273 ± 26,63 µm, respectivamente. Espessura média da camada de fibras nervosas da retina antes do YAG foi 99,89 ± 7,61 mm; e 98,50 ± 8,62 µm, 98,14 ± 8,69 µm, 99,60 ± 8,39 µm, de 99,60 ± 8,39 µm, 99,60 ± 8,35 µm, respectivamente. Nenhuma das alterações observadas foram estatisticamente significativas. As médias da pressão intraocular, também não mostraram alterações significativas. Conclusões: Não houve mudanças significativas foram encontradas na coroide, camada de fibras nervosas da retina espessuras e ópticos, após a capsulotomia por YAG laser, embora houvesse, especialmente nos primeiros dias, discretas alterações de espessura nas estruturas mencionadas.
