RESUMO
PURPOSE: To compare short-term changes in corneal endothelial cells after gonioscopy-assisted transluminal trabeculotomy(GATT). METHODS: This retrospective comparative study included 138 patients(138 eyes), and 98 of these patients underwent GATT procedure and 40 underwent SLT procedure as a control group. Changes in the corneal endothelium in patients who underwent GATT and SLT were analyzed retrospectively. Endothelial changes in the central cornea were examined using specular microscopy before and 6 months after the GATT and SLT procedure. Intraocular pressure(IOP), number of glaucoma medications, and side effects were evaluated at visits before and after two methods. RESULTS: One hundred and thirty-eight eyes of 138 patients with a mean age of 62.9±12.7 years in the SLT group and 62.5±11.8 years in the GATT group were included in this study. Pre-procedure mean ± SD IOP was 27.7±3.6 mmHg and 27.4±5.3 mmHg (p=0.173) 2.8±0.5 and 2.9±0.8 (p=0.204) glaucoma drugs are in the SLT and GATT group, respectively. The mean corneal endothelial cell density (CECD) in the SLT group was 2433.1±581.4 cells/mm2 before the procedure and 2435.1±585 cells/mm2 6 months after the procedure, a change of 0.1±0.6% which was not statistically significant (p>0.967).The mean CECD at baseline in the GATT group was 2443.4±508.2 cells/mm2 and decreased to 2290.2±527.7 cells/mm2 6 months after this procedure, representing a cell loss of 6,2±9,1% (p<0.001). CONCLUSION: GATT caused more CECD damage than SLT at the sixth month after the procedure. Considering the loss of CECD in candidates for GATT, sufficient number of endothelial cells in the central cornea is recommended.

PRCIS: Longer-term studies with a larger sample size are needed to demonstrate the superiority or equivalence of these procedures. OBJECTIVE: To evaluate the outcomes of the PAUL glaucoma implant (PGI) and Ahmed glaucoma valve (AGV) in patients with secondary glaucoma caused due to silicone oil emulsification. PATIENTS AND METHODS: A retrospective examination was conducted using the medical records of 36 patients who developed secondary glaucoma due to silicone oil emulsification after vitreoretinal surgery and then underwent PGI and AGV implantation surgery. The main outcome measures in the PGI and AGV groups were intraocular pressure (IOP) and its change, the number of antiglaucoma medications, and postoperative complications during the 12-month follow-up period. IOP of <6 mm Hg is used to define hypotonia. RESULTS: There was no statistically significant difference among the patients who underwent PGI and AGV surgeries in terms of IOP averages, both preoperatively and postoperatively on day 1, week 1, month 1, month 3, month 6, and month 12 ( P > 0.05). Before PGI and AGV implantation, the mean IOP was 40 ± 13 mm Hg and 39.3 ± 10 mm Hg, and the mean number of medications was 3.8 ± 0.4 and 4 ± 0, respectively. At the end of the 12-month follow-up period, the mean IOP was 13.5 ± 2.2 ( P < 0.001) mm Hg and 14.9 ± 4.2 ( P < 0.001) mm Hg, whereas the mean number of glaucoma medications decreased to 1.7 ± 1.3 ( P < 0.001) and 1.9 ± 1.8 ( P < 0.001) in the PGI and AGV groups, respectively. Surgical success was achieved in 17 of 18 eyes (94%) in the PGI group and 16 of 18 eyes (89%) in the AGV group. CONCLUSIONS: Although the outcomes were similar in both the PGI and AGV groups, complications requiring medical and surgical intervention were less common in the PGI group. Longer-term studies with a larger sample size are needed to demonstrate the superiority or equivalence of these procedures.

Objectives: The aim of the study was to evaluate the outcomes and complications associated with PAUL glaucoma implant (PGI) surgery in pseudoexfoliation glaucoma (PXG) patients, comparing them with a primary open-angle glaucoma (POAG) control group. Methods: A retrospective analysis included 39 PXG and 29 POAG eyes undergoing PGI surgery between January 2020 and December 2022. Surgical success was defined as intraocular pressure (IOP) between ≤21 and ≥6 mmHg at 12 months and no loss of light perception. Demographic data, ocular examinations, and complications were recorded. Results: PXG patients (68.5±9.9 years) differed significantly in age from POAG patients (54.1±10.6 years) (p<0.05). Surgical success rates at 12 months were 97.4% (PXG) and 86.2% (POAG). No significant inter-group differences in gender, laterality, lens status, vertical cup/disc ratio, or pre-operative best-corrected visual acuity were observed. Mean IOP comparisons showed significant differences within both groups (p<0.001). Ripcord suture removal occurred at mean 30.3±7.43 days (PXG) and 30.6±9.89 days (POAG). Median pre-operative AGM use was 4 (PXG) and 3 (POAG). No significant differences were noted postoperatively. Conclusion: To the best of our knowledge, this is the first study to evaluate the results of PGI in PXG and POAG, demonstrating a remarkable success rate and limited complications. Encouragingly, PXG patients with a history of unsuccessful filtration surgery demonstrated positive outcomes. The findings affirm PGI as a promising surgical intervention for PXG and POAG, exhibiting high success rates and manageable complications.
RESUMO
PURPOSE: To evaluate the safety and efficacy of the PAUL Glaucoma Implant (PGI) for managing refractory primary congenital glaucoma (PCG) over a one-year period. STUDY DESIGN: Retrospective. METHODS: A study was conducted using the medical records of thirty eyes of 17 patients who underwent PGI surgery for the treatment of refractory PCG. Primary outcome measures included failure criteria such as intraocular pressure (IOP) > 21 mm Hg, < 20% IOP reduction, necessity for further glaucoma intervention, implant removal, or loss of vision. Secondary outcomes focused on mean IOP, average number of glaucoma medications, best corrected visual acuity (logMAR), and incidence of complications. RESULTS: The mean preoperative IOP of 38.8 ± 9.2 mmHg significantly decreased to 16.1 ± 3.3 mmHg at 12 months postoperatively (p < 0.001). The average number of glaucoma medications reduced from 3.6 ± 0.5 preoperatively to 0.9 ± 1.2 at 12 months post-op. Visual acuity remained stable in 24 eyes, decreased in 4, and increased in 2. Early postoperative complications occurred in 13.3% of patients, but no late complications were reported. The cumulative success rate was 86.6%. CONCLUSION: The PGI appears to be a safe and effective option for managing refractory primary congenital glaucoma, demonstrating significant IOP reduction and decreased dependence on glaucoma medications over a one-year period, with a high success rate and manageable complication profile.
RESUMO
PURPOSE: To compare the efficacy of gonioscopy-assisted transluminal trabeculotomy (GATT) versus micropulse transscleral diode laser cyclophotocoagulation(MP-TDLC) combined with GATT in the treatment of advanced glaucoma. METHODS: This retrospective comparative study study included 82 patients (82 eyes) with a diagnosis of advanced glaucoma: 36 patients underwent GATT, and 46 underwent GATT + MP-TDLC. Intraocular pressure (IOP) changes in patients who underwent GATT and GATT MP-TDLC were analyzed retrospectively at regular intervals during the 6-month follow-up period. RESULTS: For the 82 patients included in this study, the mean ± SD IOPs before the procedures were 27.2 ± 8.5â mmHg in the GATT group and 26.6 ± 6.9â mmHg in the GATT + MP-TDLC group (p = 0.866), and the numbers of glaucoma medications used were 3.41 ± 0.5 in the GATT group and 3.36 ± 0.4 in the GATT + MP-TDLC group (p = 0.605). The mean IOP after GATT was 13.6 ± 3.9â mmHg at day 1, 13.9 ± 3.7â mmHg at week 1, 14.6 ± 4.0â mmHg at month 1, 15.3 ± 4.3â mmHg at month 3, and 14.7 ± 3.3â mmHg at month 6. In the GATT + MP-TDLC group, the postoperative day 1, week 1, month 1, month 3, and month 6 IOP values were 12.4 ± 2.5, 11.8 ± 1.8, 12.1 ± 2.0, 11.8 ± 1.09, and 11.8 ± 1.5â mmHg, respectively. CONCLUSION: GATT was found to be effective in the treatment of patients with advanced glaucoma, and results closer to the targeted low teens IOP values were obtained with GATT + MP-TDLC.
RESUMO
ABSTRACT Purposes: To identify problems caused by prosthesis-socket volume imbalances in anophthalmic sockets; and to evaluate rehabilitation with dermofat graft as a solution. Methods: We retrospectively reviewed medical records of patients operated in our clinic (between May 2011 and June 2016) with dermofat grafts to treat anophthalmic socket-related problems. During the preoperative examinations, ophthalmologists recorded the presence of eyelid problems due to the socket volume deficit, upper and lower fornix deficiency, deepening in the upper eyelid sulcus, epiphora and secretion, lower eyelid laxity, ptosis, entropion, and ectropion. Following the surgical repair, new prosthesis suitable for the resulting socket area were implemented for all the patients. The mean follow-up period was 27.42±16 months (ranging from 10-62 months). On the last control examinations, ophthalmologists recorded solved and unsolved socket problems that were present preoperatively. Results: We included 16 men and 5 women in this study. The mean age was 38.3 ± 18.4 years (range, 5-75 years). The mean duration of preoperative prosthesis use was 9.4 ± 6.8 years (range, 1-30 years). Preoperatively, 7 patients had only orbital volume deficits, and 14 had socket volume displacements in addition to the volume deficits. After the dermofat graft implantations, the remaining deficits were corrected during another surgical session: 6 patients underwent ptosis corrections, 5 lateral canthal suspensions, 5 lower fornix with mucosal graft formations, and 2 upper fornix formations with mucosal grafts. All patients were able to use prosthesis postoperatively. Conclusion: The use of dermofat grafts to correct anophthalmic socket problems caused by orbital volume deficits or volume displacements is an effective, reliable, and reproducible surgical method.
RESUMO Objetivos: Identificar os problemas causados pelo desequilíbrio do volume da cavidade da prótese em cavidades anoftálmicas, e avaliar a reabilitação com enxerto de dermofato como solução. Métodos: Revisamos retrospectivamente os prontuários de pacientes operados em nossa clínica (entre maio de 2011 e junho de 2016) com enxertos de dermofato para tratar problemas relacionados a cavidades anoftálmicas. Durante os exames pré-operatórios, os oftalmologistas registraram a presença de problemas palpebrais devido ao déficit de volume, deficiência de fórnice superior e inferior, aprofundamento no sulco palpebral superior, a epífora e secreção, flacidez palpebral inferior, ptose, entrópio e ectrópio. Após a cirurgia, novas próteses adequadas para a área de encaixe foram implementadas em todos os pacientes. O tempo médio de acompanhamento foi de 27,42 ± 16 meses (variando de 10 a 62 meses). Nos últimos exames de controle, os oftalmologistas registraram problemas corrigidos e não corrigidos da cavidade que estavam presentes no pré-operatório. Resultados: Foram incluídos 16 homens e 5 mulheres neste estudo. A média de idade foi de 38,3 ± 18,4 anos (variação de 5-75 anos). A duração média do uso de prótese pré-operatória foi de 9,4 ± 6,8 anos (variação de 1 a 30 anos). No pré-operatório, 7 pacientes apresentavam apenas déficit orbitais e 14 tinham desvios de volume, além dos déficits de volume. Após os implantes de enxerto de dermoadipação, os déficits remanescentes foram corrigidos durante outra sessão cirúrgica: 6 pacientes foram submetidos a correção de ptose, 5 suspensões de cantal lateral, 5 fórnix inferior com enxerto de mucosa e 2 formações de fórnice superior com enxerto de mucosa. Todos os pacientes foram capazes de usar prótese no pós-operatório. Conclusão: A utilização de enxertos de dermofato para corrigir problemas de anoftalmia causados por déficits de volume orbital ou deslocamento de volume é um método cirúrgico eficaz, confiável e reprodutível.

ABSTRACT Purpose: To evaluate peripapillary choroidal thickness changes in contralateral eyes of patients who had undergone evisceration of their diseased eyes. Methods: In this retrospective study, peripapillary choroidal thickness parameters in 34 eyes of 34 patients who had undergone diseased-eye evisceration between March 2014 and May 2016 were evaluated using spectral domain optical coherence tomography. The scans were manually delineated to identify the principal surfaces of Bruch's membrane, the Bruch's membrane opening, and the anterior sclera. Peripapillary choroidal thickness was measured between the Bruch's membrane and the anterior sclera at increasing distance away from the Bruch's membrane opening. The mean peripapillary choroidal thickness values in the contralateral eyes of the patients and those of the control group were compared. Results: The mean peripapillary choroidal thickness was higher in the contralateral eyes of the patients compared with that of normal eyes at all distances from the Bruch's membrane opening. Conclusion: Increased peripapillary choroidal thickness was noted in the contralateral eyes of the patients, potentially resulting in a thicker choroid. Although further investigation is required to determine the cause, these findings indicate the presence of a compensatory factor in the contralateral eyes.
RESUMO Objetivo: Avaliar as alterações da espessura coroide peripapilar em olhos contralaterais de pacientes submetidos à evisceração do olho doente. Métodos: Neste estudo retrospectivo, parâmetros da espessura coróide peripapilar de 34 olhos de 34 pacientes submetidos à evisceração, entre março de 2014 e maio de 2016, foram avaliados com tomografia de coerência óptica de domínio espectral. As varreduras foram manualmente delineadas para identificar as principais superfícies da membrana de Bruch, a abertura da membrana de Bruch e a esclera anterior. A espessura coroide peripapilar foi medida entre a membrana de Bruch e a esclera anterior a uma distância crescente da abertura da membrana de Bruch. Compararam-se os valores médios da espessura coroide peripapilar dos olhos contralaterais dos pacientes e do grupo controle. Resultados: A espessura coroide peripapilar média foi mais espessa nos olhos contralaterais dos pacientes, quando comparada com os olhos normais, em todas as distâncias da abertura da membrana de Bruch. Conclusão: O aumento da espessura coroide peripapilar foi notado nos olhos contralaterais dos pacientes. O espessamento da coroide pode ser resultante do distúrbio. Embora seja necessária uma investigação mais aprofundada para determinar a causalidade, esses achados podem apontar para um fator compensatório dos olhos contralaterais.

ABSTRACT Purpose: This study aimed to share the results of patients who underwent anterior tarsal flap rotation combined with anterior lamellar reposition because of cicatricial upper eyelid entropion, and to determine the effectiveness and reliability of this surgical technique. Methods: Fifteen eyes of 11 patients (2 right eyes; 5 left eyes; and 4 bilateral eyes) on whom we performed anterior tarsal flap rotation surgery combined with anterior lamellar reposition because of cicatricial entropion were included in this study. The medical records of the patients were analyzed retrospectively, and the causes of cicatricial entropion as well as the preoperative and postoperative ophthalmic examination findings were recorded. Normal anatomical appearance and function of eyelid were considered to have been achieved. Results: The mean age was 59.81 ± 18 years. The mean follow-up period was 21.72 ± 14 months (range, 5-43 months). The causes of cicatricial entropion were postoperative cicatrices development due to multiple electrolyzes for trichiasis and/or distichiasis in 7 eyes, trachoma in 6 eyes, and trauma in 2 eyes. Irritation and watering were detected in all patients preoperatively, whereas corneal opacity and erosion were detected in 10 patients and epithelial erosion was detected in one patient. Full anatomical and functional success was achieved for all patients. Conclusion: Anterior tarsal flap rotation combined with anterior lamellar reposition in the repair of cicatricial entropion was found to be an effective and reliable alternative surgical procedure.
RESUMO Objetivo: Compartilhar os resultados dos pacientes submetidos à rotação de retalho tarsal anterior, combinados com a reposição lamelar anterior devido à entrópio cicatricial da pálpebra superior e determinar a eficácia e a confiabilidade desta técnica cirúrgica. Métodos: Foram incluídos neste estudo quinze olhos de 11 pacientes em quem realizamos cirurgia de rotação de retalho tarsal anterior combinada com reposição lamelar anterior devido ao entrópio cicatricial. Os registros médicos dos pacientes foram analisados retrospectivamente e as causas da entrópio cicatricial, bem como os achados do exame oftalmológico pré-operatório e pós-operatório foram registrados. A integridade anatômica e funcional da pálpebra foi considerada como sucesso cirúrgico. Resultados: A idade média foi de 59,81 ± 18 anos. O período médio de seguimento foi de 21,72 ± 14 meses (intervalo 5-43 meses). As causas da entrópio cicatricial foram o desenvolvimento de cicatrizes pós-operatórias devido a eletrólises múltiplas para triquíase e/ou distiquiase em 7 olhos, tracoma em 6 olhos e trauma em 2 olhos. Todos os pacientes foram tiveram irritação e lacrimejamento pré-operatório, enquanto que 10 pacientes apresentavam opacidade e erosão da córnea e 1 paciente apresentava apenas erosão epitelial. O sucesso total anatômico e funcional foi alcançado em todos os casos. Conclusão: A rotação do retalho tarsal anterior combinada com a reposição lamelar anterior no reparo da entrópio cicatricial é um procedimento cirúrgico alternativo efetivo e confiável.
