Here we report three cases of flap-related complications following temporal inverted internal limiting membrane (ILM) flap technique for the repair of macular holes (MH). The first case showed a flap closure pattern in which the MH completely closed at 2 months spontaneously. The second case showed early anatomical and functional improvement provided by an immediate closure of the MH but developed flap contracture and nasally located epiretinal membrane (ERM) at postoperative 18 months. There was no functional deterioration, thus no further intervention was required...

Coronavirus disease 2019 (COVID-19) is a procoagulant disease that increases the risk of clinically evident thrombotic complications. Herein we present 3 cases with different retinal artery occlusions that emerged soon after the diagnosis of COVID-19. The first patient had central retinal artery occlusion (CRAO) that resulted in visual loss in one eye. The second patient had inflammatory peripheral retinal artery occlusion, vasculitis, and uveitis which did not affect vision. The third patient presented with CRAO following the progression from orbital cellulitis to orbital apex syndrome...

An ophthalmology consultation was requested for a 29-year-old woman complaining of visual field defects. The patient had presented to the emergency department with cough and high fever one day earlier. Chest computed tomography demonstrated pneumonia and two severe acute respiratory syndrome coronavirus 2 polymerase chain reaction tests were positive. The patient had undergone renal transplantation 11 years ago due to glomerulonephritis. Best-corrected visual acuity (BCVA) was 20/40 in the right eye and 20/30 in the left eye...

Various physiological systems and behaviors such as the sleep-wake cycle, vigilance, body temperature, and the secretion of certain hormones are governed by a 24-hour cycle called the circadian system. While there are many external stimuli involved the regulation of circadian rhythm, the most powerful environmental stimulus is the daily light-dark cycle. Blind individuals with no light perception develop circadian desynchrony. This leads to non-24-hour sleep-wake rhythm disorder, which is associated with sleep-wake disorders, as well as mood disorders and loss of appetite and gastrointestinal disturbances due to disrupted circadian hormone regulation...

OBJECTIVES: The new coronavirus disease 2019 (COVID-19) pandemic emerged in Wuhan, China in October 2019 and spread rapidly all over the world, making extended mask use an inescapable rule of daily life. Literature data indicate that the use of face masks increases the symptoms of dry eye in addition to preventing the spread of COVID-19. The aim of our study was to evaluate the relationship between the clinical signs and symptoms of dry eye and the duration of mask use in healthy individuals using regular face masks...

Fibrous dysplasia is a benign, rare bone disease in which bone is replaced by fibro-osseous tissue to varying degrees. It can present differently depending on the amount of compression caused by the fibro-osseous tissue. Patients are usually asymptomatic, but symptoms related to cranial nerve compression may occur. In this case report, we describe a 45-year-old woman with sphenoid bone dysplasia which compressed the optic nerve and caused unilateral optic disc cupping that mimicked glaucoma. Our case highlights the importance of including compressive etiologies associated with optic disc cupping in the differential diagnosis of glaucoma...

A 50-year-old man with recurrent pterygium and a 46-year-old woman with primary pterygium underwent surgery using a novel autograft transfer technique that facilitates autograft suturing and ensures correct graft orientation. After removing the pterygium, three edges of the autograft were cut. The autograft was flipped first over the uncut edge and secured to the superior margin of the recipient bed with two sutures. Afterward, the fourth side of the graft was cut and the second flip was done over the sutured edge...

This study presents the long-term clinical results of Argus II retinal prosthesis implantation in eyes with light perception and projection in 3 patients with end-stage retinitis pigmentosa. No conjunctival erosion, hypotony, or implant displacement was observed during postoperative follow-up. The electrical threshold values were lower in the macular region and higher close to the tack fixation region and peripherally.
