RESUMO

This was a report about a pseudophakic patient who experienced isolated total aniridia without damage to other intraocular structures following blunt trauma to the eye. This patient had a history of uneventful cataract surgery using a small clear corneal incision (CCI). This 71-year-old male presented at our clinic with glare in his left eye. He reported that he had fallen down while drunk and struck his left eye against a stone on the road 15 days earlier. He had undergone cataract surgery on his left eye nine months before the accident at another eye clinic. Slit-lamp examination showed total aniridia in his left eye, but there was no hyphema or cells in the anterior chamber. The intraocular lens in his left eye was stable, without decentration, dislocation, or zonular dehiscence and remained in an intact capsular bag. Review of the medical records from the surgical clinic at which he had undergone cataract surgery indicated no specific findings for any intraocular structure including the iris. He had previously undergone an uneventful phacoemulsification for his left eye through a 2.2 mm CCI, followed by the implantation of a single piece acrylic intraocular lens inside an intact capsular bag. This report showed that small-sized CCIs can be opened postoperatively by trauma and that this can result in isolated total aniridia without damage to other intraocular structures.

RESUMO

ABSTRACT This was a report about a pseudophakic patient who experienced isolated total aniridia without damage to other intraocular structures following blunt trauma to the eye. This patient had a history of uneventful cataract surgery using a small clear corneal incision (CCI). This 71-year-old male presented at our clinic with glare in his left eye. He reported that he had fallen down while drunk and struck his left eye against a stone on the road 15 days earlier. He had undergone cataract surgery on his left eye nine months before the accident at another eye clinic. Slit-lamp examination showed total aniridia in his left eye, but there was no hyphema or cells in the anterior chamber. The intraocular lens in his left eye was stable, without decentration, dislocation, or zonular dehiscence and remained in an intact capsular bag. Review of the medical records from the surgical clinic at which he had undergone cataract surgery indicated no specific findings for any intraocular structure including the iris. He had previously undergone an uneventful phacoemulsification for his left eye through a 2.2 mm CCI, followed by the implantation of a single piece acrylic intraocular lens inside an intact capsular bag. This report showed that small-sized CCIs can be opened postoperatively by trauma and that this can result in isolated total aniridia without damage to other intraocular structures.


RESUMO Relatamos um paciente com história de cirurgia de catarata sem intercorrências usando uma pequena incisão na córnea clara (CCI), que apresentou aniridia total isolada, sem danos a outras estruturas intraoculares, após trauma contuso no olho. Um homem de 71 anos de idade apresentou-se em nossa clínica referindo brilho no olho esquerdo. Ele relatou que, 15 dias antes, havia caído enquanto estava bêbado e atingiu seu olho esquerdo contra uma pedra na estrada. Ele havia passado por uma cirurgia de catarata no olho esquerdo, nove meses antes do acidente em outro serviço. Exame de lâmpada de fenda mostrou aniridia total de olho esquerdo, sem hifema ou células na câmara anterior. A lente intraocular no olho esquerdo ficou estável, com o saco capsular restante intacto, sem descentralização, luxação ou deiscência zonular. O exame dos registros médicos do serviço em que ele havia se submetido a uma cirurgia de catarata não mostraram relatos específicos a qualquer estrutura intraocular, incluindo a íris. O olho esquerdo fora submetido à facoemulsificação sem complicações, através de um CCI de 2,2 mm, seguido pela implantação de uma lente intraocular acrílica peça única dentro do saco capsular intacto. Este relatório mostra que, mesmo pequenas CCIs podem ser abertas no pós-operatório por trauma e que isso pode resultar em aniridia total isolada, sem danos a outras estruturas intraoculares.

RESUMO

Nucleotide sequence analyses of the Pvs48/45 and Pvs47 genes were conducted in 46 malaria patients from the Republic of Korea (ROK) (n = 40) and returning travellers from India (n = 3) and Indonesia (n = 3). The domain structures, which were based on cysteine residue position and secondary protein structure, were similar between Plasmodium vivax (Pvs48/45 and Pvs47) and Plasmodium falciparum (Pfs48/45 and Pfs47). In comparison to the Sal-1 reference strain (Pvs48/45, PVX_083235 and Pvs47, PVX_083240), Korean isolates revealed seven polymorphisms (E35K, H211N, K250N, D335Y, A376T, I380T and K418R) in Pvs48/45. These isolates could be divided into five haplotypes with the two major types having frequencies of 47.5% and 20%, respectivelfy. In Pvs47, 10 polymorphisms (F22L, F24L, K27E, D31N, V230I, M233I, E240D, I262T, I273M and A373V) were found and they could be divided into four haplotypes with one major type having a frequency of 75%. The Pvs48/45 isolates from India showed a unique amino acid substitution site (K26R). Compared to the Sal-1 and ROK isolates, the Pvs47 isolates from travellers returning from India and Indonesia had amino acid substitutions (S57T and I262K). The current data may contribute to the development of the malaria transmission-blocking vaccine in future clinical trials.
