Central Serous Chorioretinopathy after Rhinoplasty
We report a case of central serous chorioretinopathy after rhinoplasty for deviation of the nasal septum in a 23-year-old Caucasian man. The patient complained of deterioration of vision in the right eye 4 days after rhinoplasty. At presentation, visual acuity of the right eye was 6/9 with metamorphopsia. Fluorescein angiography revealed a focal retinal pigment epithelium leakage and optical coherence tomography an increase in macular thickness to 245 μm. The left eye was normal. One month after the operation, without any treatment, visual acuity returned to 6/6, the leakage of the retinal pigment epithelium disappeared and the macular thickness returned to 183 μm. To the best of our knowledge, central serous chorioretinopathy after rhinoplasty has not been previously reported. This case report shows a possible association between the postoperative stress and central serous chorioretinopathy. Moreover, it widens the spectrum of drugs associated with the occurrence of the disease
Effects of combined abiotic stresses on nutrient content of European wheat and implications for nutritional security under climate change
Climate change is causing problems for agriculture, but the effect of combined abiotic stresses on crop nutritional quality is not clear. Here we studied the effect of 10 combinations of climatic conditions (temperature, CO2, O3 and drought) under controlled growth chamber conditions on the grain yield, protein, and mineral content of 3 wheat varieties. Results show that wheat plants under O3 exposure alone concentrated + 15 to + 31% more grain N, Fe, Mg, Mn P and Zn, reduced K by − 5%, and C did not change. Ozone in the presence of elevated CO2 and higher temperature enhanced the content of Fe, Mn, P and Zn by 2–18%. Water-limited chronic O3 exposure resulted in + 9 to + 46% higher concentrations of all the minerals, except K. The effect of climate abiotic factors could increase the ability of wheat to meet adult daily dietary requirements by + 6% to + 12% for protein, Zn and Fe, but decrease those of Mg, Mn and P by − 3% to − 6%, and K by − 62%. The role of wheat in future nutrition security is discussed
Mutations in FRMD7, a newly identified member of the FERM family, cause X-linked idiopathic congenital nystagmus.
Idiopathic congenital nystagmus is characterized by involuntary, periodic, predominantly horizontal oscillations of both eyes. We identified 22 mutations in FRMD7 in 26 families with X-linked idiopathic congenital nystagmus. Screening of 42 singleton cases of idiopathic congenital nystagmus (28 male, 14 females) yielded three mutations (7%). We found restricted expression of FRMD7 in human embryonic brain and developing neural retina, suggesting a specific role in the control of eye movement and gaze stability
Mutations in FRMD7, a newly identified member of the FERM family, cause X-linked idiopathic congenital nystagmus
Idiopathic congenital nystagmus (ICN) is characterised by involuntary, periodic, predominantly horizontal, oscillations of both eyes. We identified 22 mutations in FRMD7 in 26 families with X-linked idiopathic congenital nystagmus. Screening of 42 ICN singleton cases (28 male, 14 females) yielded three mutations (7%). We found restricted expression of FRMD7 in human embryonic brain and developing neural retina suggesting a specific role in the control of eye movement and gaze stability

Secondary DMEK following failed primary DMEK
Purpose To report the outcomes of secondary Descemet Membrane
Endothelial Keratoplasty (DMEK) performed for failed primary DMEK.
Methods The medical records of all patients undergoing secondary DMEK
due to failure of primary DMEK were reviewed. Reasons for failure were
sought and best-corrected visual acuity (BCVA), endothelial cell density
(ECD) and complications of secondary DMEK were evaluated. Results A
total of 10 cases undergoing secondary DMEK following failed primary
DMEK were identified. Presumed reasons for failure included donor ECD <=
2300 cells/mm(2) (n = 4), difficulty during graft preparation (n = 2),
graft detachment (n = 2), acute angle closure due to retroiridal air
dislocation (n = 1), inverse graft positioning (n = 1) and
phacoemulsification (n = 1). Eyes with low visual potential were not
excluded from the study group. We should note that one patient (case
no7) had both low ECD and graft detachment as reasons for failure and as
a result he is counted twice. Median BCVA (decimal fraction) increased
from 0.1 (range, 0.01; 0.3) to 0.5 (0.05; 1.0) at one month and remained
stable thereafter. A BCVA of 0.5 or higher was achieved in 7 cases at
the final follow-up. Mean ECD fell from 2628 +/- 284 cells/mm(2) to 1391
+/- 252cells/mm(2) at 6 months (47% reduction) and 959 +/-
225cells/mm(2) at 24 months (64% reduction) (P <= 0.028). Complications
included the incomplete removal of the primary graft and mild iris
bleeding, decompensation of a preexisting primary open-angle glaucoma
and retroiridal air dislocation. Conclusions Apart from low donor ECD,
surgical challenges, i.e., difficulty with graft preparation, inverse
graft positioning, and retroiridal air dislocation, were main reasons
for failure of primary DMEK. Secondary DMEK showed a good safety profile
and reasonable visual outcomes
