Trabeculectomy ab interno (trabectome)

This retrospective study examines the outcome of trabectome surgery in nine phakic patients with Posner-Schlossman syndrome with uncontrolled IOP >30mmgHg. Cytomegalovirus (CMV) DNA was verified by polymerase chain reaction (PCR) in aqueous humour samples. Patients were treated with oral valganciclover...

Light reflex in preterm infants

In this study, the pupillary size and light reflex was examined in premature infants using infrared video-pupillography and stimuli of red and blue light. Only eyes of infants without retinopathy of prematurity were included in the study. Pupillary light reflexes...

Twenty-four hour IOP patterns in patients with thyroid eye disease (OO/GL)

Elevated IOP in patients with thyroid eye disease (TED) can be caused by restriction and compression of the globe by enlarged extraocular muscles, elevated episcleral venous pressure and increased mucopolysaccharide deposition in the trabecular meshwork. Although previous studies have investigated...

How common is ocular trauma in children and what are the clinical features?
