    Chiasmal decussation in tilted disc syndrome PVER in tilted disc
    (Swets en Zeitlinger B.V., 1999) Öztürk F.; Kurt E.; Yoldaş T.; Ilker S.S.; Inan Ü.Ü.
    The tilted disc syndrome is a benign congenital abnormality of the optic nerve head. Since it can be confused with papilledema and chiasmal lesions, differential diagnosis is important. The tilting anomaly may be associated with other abnormalities along the optic nerve. Visual field defects may be similar to those in chiasmal lesions. In order to determine whether the normal crossover of nerve fibers at the chiasm is altered, the crossed and the uncrossed fibers were investigated using the pattern visual evoked responses (PVER) test. Thirty-four eyes of 17 patients diagnosed with tilted disc syndrome were evaluated for refraction, keratometry, color vision with Ishihara, visual field, and PVER. The presence of abnormal nerve fiber decussation was determined by recording PVER from the electrodes mounted on the scalp of both hemispheres. The amplitude and latency differences between the 'crossed' and 'uncrossed' fibers were not statistically significant (p>0.05). As a result, the tilting abnormality of papilla was found to be without chiasmal abnormal decussation.

    Triple A syndrome with clinical and genetic findings: A case report; [Klinik ve genetik bulgulari ile triple A sendromu: Bir vaka takdimi]
    (Cocuk Sagligi ve Hastaliklan Dergisi, 2014) Appak Y.Ç.; Çam F.S.; Şahin G.E.; Uluçay S.; Huebner A.; Kasirga E.
    Triple A syndrome (Allgrove syndrome) is a rare autosomal recessive disease characterized by achalasia, alacrima, adrenal insufficiency, and progressive neurological syndrome. This syndrome is caused by mutations in the achalasia-addisonianism-alacrima syndrome (AAAS) gene in the chromosome 12q13 region. We present a nine-year-old boy who had vomiting and progressive dysphagia since six years of age. Achalasia was determined with barium esophagography and esophagus manometric investigation. He had positive Schirmer test (<5 mm) and bilateral optic disc atrophy. The patient's serum cortisol levels were normal and cortisol response was low with ACTH stimulation test. Genetic analysis revealed a homozygous mutation (c.1066-1067delCT) in exon 11 of the AAAS gene, and her younger brother and sister were heterozygous carriers of this mutation. For treatment of achalasia, calcium channel blocker therapy was started, and botulinum toxin was applied to the distal esophagus. The patient's vomiting decreased but continued; his symptoms resolved after the implementation balloon dilation of the esophagus. © 2014, Cocuk Sagligi ve Hastaliklan Dergisi. All rights reserved.
