Abstract
A 62-year-old man presented with diplopia, ocular ductional deficits, and sluggish pupils. Pupillometry demonstrated large hyporeactive pupils with no evidence of damage to the sympathetic or parasympathetic innervation, indicating a myopathy of the iris musculature. A single large deletion in mitoc...

Abstract
Results obtained in the study are discussed and compared with the related current literature. The overall mortality in 113 patients was 56.6%. CONCLUSION: According to the results, the most important determinants of the prognosis are GCS score of the patient on admission, abnormality in pupil reacti...

Abstract
Vision was NLP in all eyes at the time of surgery, which was performed 3 days to 14 days after the initial trauma. During a mean follow-up period of 20.5 +/- 5.2 months (range, 11-36 months), except for 1 case of phthisis, other eyes achieved acceptable anatomical and functional outcomes. Postoperat...

Abstract
We report two Creutzfeldt-Jakob disease (CJD) patients with rhythmic pupillary and palpebral oscillation who had a mutation of prion protein codon 200 that resulted in the substitution of lysine for glutamate (Glu/Lys). Alternating dilation and constriction of the pupils combined with elevation and...

Abstract
We identified complex interactions and mutual information in many of the parameters. Variables predicting death differ from those predicting unfavorable versus favorable outcomes (Glasgow Outcome Scale scores of 1-3 versus 4-5 [GOS]). The most important parameter for prediction of unfavorable outcom...

Abstract
We describe the case of a 78-year-old highly myopic woman who had bilateral phacoemulsification with posterior chamber intraocular lens implantation. During surgery, the anterior chamber was extremely deep and the pupil was excessively dilated, consistent with lens-iris diaphragm retropulsion syndro...

We report a penetrating orbital injury caused by a bread knife that extended from the orbit to the tegmental dura mater of the temporal bone. The knife's main trajectory coursed through the temporal lobe. Adjacent cerebral structures were explored before removal of the knife....

Abstract
The median age at diagnosis was 1.6 years (range, 0-5.9) with a median follow-up of 1.8 years (range, 0.1 to 11.6). The median time from presenting signs to the time of diagnosis was 5.2 months (range, 0-25.2). Common presenting signs of retinoblastoma were identified; the most common of which were...

Abstract
A secondary angle closure associated with DSEK is reported with air migrating behind the iris, resulting in extensive iridocorneal adhesions. An acute increase in IOP after DSEK can also be induced by air anterior to the iris causing pupillary block. IOP spikes are much more common in the first few...

Abstract
This binocular pupillometer identified all of our patients with > 0.5 log unit rAPDs. Using NDFs, all of our abnormal patients were accurately identified and their rAPDs quantified. Variability in some normals makes them indistinguishable from patients with subtle rAPDs....

Abstract
Ninety-two (7.8%) of 1172 patients had a GCS of 3 and BFDP; eight had 'good', 84 had 'poor' recovery. We found no significant differences in sex (79% male), age (median 32 years), and trauma mechanisms. Trauma was significantly less severe, probability of survival significantly higher (0.48 vs. 0.23...

Pupil tests provide a convenient and simple method for evaluation of autonomic function. Most patients with autonomic disorders show evidence of sympathetic or parasympathetic deficits in the pupil, and these can be detected using a combination of clinical signs, pupillometric tests (measuring the r...

Abstract
Traumatic optic neuropathy is a severe complication of a head or face trauma. Diagnosis is established by analyzing pupillary responses to light. Fundus examination and orbital CT scan help to localize the site of the lesion and may show a fracture involving the optic canal. Surgical decompression o...

Ninety-three patients fulfilled the criteria for inclusion into the study. There were 6 survivors who were all less than 28 years of age, had at least one GCS score above 3 in the pre-hospital phase and were more likely to have had an evacuable mass lesion on CT brain scan and undergo craniotomy. Of...

A 25-year-old woman was diagnosed to have tubercular meningitis (TBM) with a right parietal infarct. She responded well to four-drug anti-tubercular treatment (ATT), systemic steroids and pyridoxine. Steroids were tapered off in one and a half months; she was put on two-drug ATT after two months. Si...

We present a case of a patient who had pupilloplasty for an atonic pupil following phacoemulsification cataract surgery. Postoperatively, the patient experienced glare that was not relieved by a neodymium:YAG laser capsulotomy. A cosmetic contact lens helped to resolve the symptoms. In cases of glar...

Loss-of-function mutations in laminin beta2 (LAMB2) cause a broad range of ocular pathology, emphasizing the importance of laminin beta2 in eye development. Patients with Pierson syndrome can initially present with ocular signs alone. In newborns with marked bilateral microcoria, Pierson syndrome sh...

Because either syndrome may occur alone, damage is apparently selective. Among the patients with harlequin syndrome who also have tonic p...

Abstract
There were only 3 dislocations into the anterior chamber in this series of 200 consecutive eyes (1.5% dislocation rate) and all were successfully reattached with a second air bubble. There were no dislocations in the last 115 consecutive cases. There were two cases of donors that were attached but d...

Cataract remains the most important cause of preventable blindness in this poor region of China, and affordable provision of surgery would help to address this problem. Some cases of cataract blindness may not be preventable owing to preexisting comorbidity, as detected by the presence of a pupillar...

Abstract
Our results suggest that both parasympathetic and sympathetic pupillary functions are disturbed already early in the course of MS. However, the disturbance is not severe at this stage of the disease. The dysfunction is age-dependent and thus possibly related to the dimished remyelination capacity of...

We present a case of acute angle closure that occurred after insertion of an implantable contact lens (ICL). The apparent papillary-block angle closure did not resolve after 2 patent iridotomies and a surgical iridectomy, but did respond to pupil dilation (not constriction). Ultrasound biomicroscopy...

Abstract
It was demonstrated that the pupillary light reflex (PLR) depends on the input of suprageniculate neurons, thus supporting the involvement of a cortical pathway also. The site of integration of cortical signals in relation to the PLR into the pupillomotor pathway may be located suprageniculately in...
