Introduction: Upgaze paralysis due to supranuclear defects can cause significant visual symptoms. There are only a few reports on the treatment of this problem in the literature. Patients with Parinaud's syndrome may also have retraction nystagmus and convergence on attempted upgaze that further complicates the treatment.
Methods: We performed a retrospective review of 48 patients with Parinaud's syndrome. Eleven patients were not able to elevate to the primary position and underwent surgery for the upgaze defect. Surgical treatments included transpositions in 2 patients, inferior rectus recessions in 8, which was combined with a superior rectus resection in one.
Results: Preoperative duction measurements demonstrated an average limitation on upgaze to -19 degrees (-10 to -30) below midline with zero representing midline. Postoperative measurements showed marked improvement to +19 degrees above midline (15 to 30). Inferior rectus recessions were as effective as transpositions in restoring function. In addition, there was a marked reduction in the retraction nystagmus and upgaze convergence as well.
Conclusions: Visually significant upgaze limitation can be relieved with bilateral inferior rectus recessions in Parinaud's syndrome. Retraction nystagmus and convergence movements are also markedly improved.

Clinical spectrum of positional downbeat nystagmus: a diagnostic approach.
J Neurol

Positional downbeat nystagmus (pDBN) is a common finding in dizzy patients, with etiologies ranging from benign paroxysmal positional vertigo (BPPV) to central vestibular lesions. Although peripheral pDBN often presents with distinct clinical features that differentiate it from BPPV, diagnosing its etiology can be challenging. A thorough clinical evaluation, including the physical characteristics of the nystagmus, response to positional maneuvers, and neurological findings, is often sufficient to diagnose conditions that provoke pDBN such as anterior canal BPPV, atypical posterior canal BPPV, and central causes.

This report describes the longest case of a retained metallic intraorbital foreign body with no complications and development of delayed sensory exotropia following traumatic sclopetaria in childhood. A 9-year-old girl suffered a BB gun injury to the left eye, leading to chorioretinitis sclopetaria and loss of vision. The visual acuity was 20/800 with a relative afferent pupillary defect and choroidal rupture with subretinal hemorrhage that evolved to sclopetaria over time.

Post Graduate Institute of Medical Education and Research, Chandigarh, India.
Purpose: Reoperations in strabismus are reportedly needed in 20-40% of cases undergoing surgery. The present study investigated the outcomes of reoperations based on preoperative imaging of extraocular muscle insertions, and whether the Anterior Segment Optical Coherence Tomography (ASOCT) was of value.
Methods: Patients with strabismus requiring reoperation with/without previous surgical records at the Advanced Eye Centre, PGIMER, Chandigarh were recruited.

Progressive supranuclear palsy (PSP) is a rare, atypical parkinsonism, characterized by the presence of intracerebral tau protein aggregates and determined by a wide spectrum of clinical features. The definitive diagnosis is postmortem and is identified through the presence of neuronal death, gliosis, and aggregates of the tau protein presented in the form of neurofibrillary tangles (MNF) with a globose appearance in regions such as the subthalamic nucleus, the substantia nigra, and the globus pallidus The findings in ancillary imaging studies, as well as fluids biomarkers, are not sufficient to support diagnosis of PSP but are used to rule out similar pathologies because there are still no specific or validated biomarkers for this disease. The current treatment of PSP is focused on reducing symptoms, although emerging therapies seek to counteract its pathophysiological mechanisms.
