Evaluation of the Ex-PRESS(®) P-50 implant under scleral flap in combined cataract and glaucoma surgery.

AIM: To evaluate the efficacy and safety of glaucoma drainage device Ex-PRESS(®) P-50 for combined cataract surgery and glaucoma. METHODS: Patients having cataract and open angle glaucoma or patients with open advanced glaucoma which needed two or more antiglaucoma medications were included. Combined cataract surgery and glaucoma with Ex-PRESS(®) P-50 model placed under scleral flap was performed. RESULTS: Out of 40 eyes of 40 patients (55% male and 45% female) completed the study during one-year follow-up. The mean of age was 76.6±11.02y. The intraocular pressure (IOP) decreased significantly during the 12-month follow-up from 23.5 mm Hg to 16.8 mm Hg (Wilcoxon signed ranks test, P<0.001). A 59.5% of patients did not need any topical treatment, 10.8% of them needed one active principle, 27% needed two active principles, and 2.7% of them needed three active principles for successful IOP control (<21 mm Hg). CONCLUSION: Combined surgery of phacoemulsification with ExPRESS(®) P-50 lowers IOP from the preoperative baseline and reduces significantly the number of antiglaucoma active principles for IOP control after the operation.

The relationship between floppy eyelid syndrome and obstructive sleep apnoea.

PURPOSE: To determine the prevalence of eyelid hyperlaxity and floppy eyelid syndrome (FES) in obstructive sleep apnoea (OSA), and the presence of OSA in FES. PARTICIPANTS: One-hundred and fourteen patients who had been consecutively admitted for OSA evaluation and 45 patients with FES in which sleep studies were recorded. METHODS: Subjects underwent eyelid laxity measurement, slit-lamp examination and polysomnography. RESULTS: Eighty-nine patients were diagnosed of OSA. Fourteen patients with OSA had FES (16%) and 54/89 (60.67%) had eyelid hyperlaxity. Two of the 25 non-OSA patients had FES (8%) and 8 of 25 (32%) had eyelid hyperlaxity. There was a significantly higher incidence of eyelid hyperlaxity in OSA than in non-OSA patients (p=0.004). Thirty-eight of the 45 patients with FES were diagnosed of OSA (85%) and 65% had severe OSA. CONCLUSIONS: OSA might be an independent risk factor for eyelid hyperlaxity and severe OSA is common in patients with FES.

Pterygium surgery by means of conjunctival autograft: long term follow-up.

PURPOSE: To demonstrate the long term of follow-up of the recurrence rate after conjunctival autograft for pterygium surgery. METHODS: A total of 112 patients operated for pterygium with conjunctival autografts and with more than one year follow-up were registered. Patients were called for voluntary examinations of their respective ocular surface statuses. Completing the study was only possible in 44 cases. Seven had bilateral pterygium. (N=51 operated pterygium). RESULTS: The mean follow-up time was 49.06 months. In 29.45% of the cases, attachment was performed using non-absorbable sutures (nylon 10/0), while fibrin glue was used in 70.55% of the cases. Six cases of recurrence (11.76%) were found. The recurrence rate between primary and recurrent pterygium, and between sutures and fibrin glue proved to be not statistically significant; p>0.05. There were no significant differences between women and men with respect to recurrence. The median of age in the recurrence group was 40 years old, in contrast to 55 in the non-recurrence group; p=0.01517. All of these recurrences were associated with patients of Hispanic origins (from Latin America); p=0.001506. CONCLUSIONS: After a long follow-up period after autograft pterygium surgery, there were no statistically significant differences in recurrence rates for the application of sutures as opposed to fibrin glue; similarly, there were no statistically significant differences between the use of autograft in primary and recurrent pterygium. The greatest risk factors for recurrence were young age and Hispanic ethnicity.

OBJETIVO: Demonstrar a taxa de recorrência em cirurgia do pterígio com transplante autólogo de conjuntiva após um acompanhamento a longo prazo. MÉTODOS: Cento e doze pacientes operados de pterígio e transplante autólogo de conjuntiva, com mais de um ano de acompanhamento foram registrados. Os pacientes foram chamados para um exame voluntário de estado da superfície ocular. O estudo completo só foi possível em 44 pacientes. Sete deles tinha tido pterígio bilateral. (N=51). RESULTADOS: A média de acompanhamento a partir do momento da cirurgia até o exame foi de 49,06 meses. A sutura não-absorvível (nylon 10/0) foi usada em 29,45% dos casos, enquanto que a cola biológica de fibrina foi usada em 70,55%. A recidiva do pterígio foi detectada apenas em 6 casos (11,76%). As recidivas entre pacientes operados de pterígio primário e recorrente, e entre o uso de suturas ou cola de fibrina não foram significativos (p>0,05). Também não houve diferença significativa na recorrência com relação ao sexo. A idade média no grupo de recidiva foi de 40 anos e no grupo sem recidiva de 55 anos (p=0,01517). Todas essas recorrências ocorreram em pacientes de origem hispânica (América latina) (p=0,001506). CONCLUSÕES: A longo prazo da remoção cirúrgica de pterígio utilizando um transplante autólogo de conjuntiva, não há diferença estatisticamente significativa com o uso de sutura ou cola de fibrina. Também não há diferenças na recidiva, se o transplante autólogo de conjuntiva utilizado for em casos primários ou recorrentes de pterígio. O maior fator de risco para a recorrência parece estar entre os jovens e pacientes de etnia hispânica.
