ABSTRACT
·AIM: To investigate 3-year results in our neovascular age-related macular degeneration (NV-AMD) patients treated with Ranibizumab. ·METHODS:Retrospective study. Visual acuity (VA), a full biomicroscopic examination (anterior segment and fundus), and optical coherence tomography (OCT) findings were noted at every visit. All patients were followed monthly. The VA values for the visits closest to 12,24, and 36mo were analysed. Totally 101 eyes of 73 patients were enrolled. According to the initial VA, the patients were divided three groups: initial VA ≤ 35 (Group 1),36-54 (Group 2),and≥55 letters(Group 3). After three loading doses of 0. 5 mg Ranibizumab if retreatment was needed,again,0.5 mg Ranibizumab was administered. ·RESULTS: Totally 57 of the 101 eyes were from males and 44 were from females. The average age was 75.1y. The difference on the changes of VA among three groups at 24 and 36mo were statistically significant (P=0.002 and 0.0001 respectively). At the end of the 36-month follow-up the VA increase in Group 2 was significant(P=0.001). At the 12,24 and 36mo visits most of the eyes showed no VA loss and most of these eyes were in Group 1. The average number of injections administered was 7.3 and the average number of visits was 23. 9 during the follow-up. · CONCLUSION: VA improvement was significant in those with mild initial VA (36-54 letters). Most eyes showed no VA loss regardless of the initial VA. No correlation between the final VA and the average number of injections.
ABSTRACT
ABSTRACT Purpose: To compare the effects of 90° and 180° conjunctival rotational autograft (CRA) techniques used in primary pterygium surgery. Methods: Forty-five patients were included in this retrospective study. Visual acuity (VA), corneal topography, and auto-refractometer measurements, as well as detailed biomicroscopic examinations, were performed preoperatively and postoperatively. During surgery, the pterygium tissue was excised then rotated 90° in Group 1 and180° in Group 2, after which it was sutured to the bare sclera. Pterygium recurrence was defined as corneal invasion ≥1 mm. Results: Group 1 consisted of 21 patients with a mean age of 45.1 ± 11.8 years, while Group 2 comprised 24 patients with a mean age of 47.9 ± 13.8 years. The pterygia in Group 1 were graded as more advanced than those in Group 2. A similar number of recurrences were observed in Group 1 (14.3%) and in Group 2 (16.7%). There was no statistically significant difference in terms of the preoperative and postoperative VA and astigmatism values between the two groups. There was a statistically significant improvement in the postoperative VA and astigmatism values in Group 1 and in the postoperative astigmatism values in Group 2. Although postoperative redness was more common in Group 1, no statistically significant difference was found between the groups. Conclusion: BothCRA techniques can be successful in patients for whom it is desirable to avoid a conjunctival autograft and for patients without high cosmetic expectations.
RESUMO Objetivo: Comparar os efeitos das técnicas de auto-enxerto rotacional de conjuntiva (CRA) de 90° e 180°, usadas na cirurgia de pterígio primário. Métodos: Quarenta e cinco pacientes foram incluídos neste estudo retrospectivo. Acuidade visual (AV) pré e pós-operatória, topografia da córnea, auto-refratometria e exames biomicroscópicos detalhados foram feitos. Durante a cirurgia, o tecido de pterígio foi excisado e o mesmo tecido foi girado 90° no Grupo 1 e 180° no Grupo 2, após o que foi suturado à esclera nua. A recorrência do pterígio foi definida como invasão da córnea ≥1 mm. Resultados: O Grupo 1 consistiu em 21 pacientes, cuja média de idade foi de 45,1 ± 11,8 anos e o Grupo 2 compreendeu 24 pacientes, cuja idade média foi de 47,9 ± 13,8 anos. O Grupo 1 teve maior frequência de pterígios classificados como mais avançada do que no Grupo 2. Um número similar de recorrências foi observado no Grupo 1 (14,3%) e no Grupo 2 (16,7%). Não houve diferença estatisticamente significativa em termos de valores pré e pós-operatórios de AV e astigmatismo entre dois grupos. Houve uma melhora estatisticamente significativa nos valores pós-operatórios de AV e astigmatismo no Grupo 1 e nos valores de astigmatismo pós-operatório no Grupo 2. Embora a vermelhidão pós-operatória tenha sido detectada mais comumente no Grupo 1, não foi encontrada diferença estatisticamente significante entre os grupos. Conclusão: Ambas as técnicas de CRA podem ser bem sucedidas em pacientes onde é desejável evitar um auto-enxerto conjuntival livre e para quem a expectativa de cosméticos não é alta.
