Objetivo: Avaliar a efetividade e as complicações com a aplicação do 5- fluorouracil (5-FLU) no intra-operatório da cirurgia do pterígio. Método: Foram avaliados 28 olhos de 26 indivíduos quanto ao tipo e tamanho do pterígio, cirurgias prévias e a resposta ao tratamento cirúrgico (no 7º , 21º , 60º e 90º dia de pós-operatório). Logo após a exerese do pterígio, aplicou-se 5-FLU (25 mg/ml) no leito cirúrgico, durante cinco minutos; a seguir, realizou-se a técnica de deslizamento de retalho conjuntival. Resultados: A maioria dos pacientes tinha mais de 50 anos de idade e apresentava pterígio primário (70,0%), grau II (60,7%), do tipo involutivo (60,7%). No pós-operatório observaram-se: isquemia (10,7%), deiscência da conjuntiva (7,1%), ceratite (3,5%), conjuntivite (3,5%) e recidiva da lesão em 1 olho (3,5%).Conclusão: O 5-FLU se mostrou droga segura e efetiva na prevenção das recidivas, podendo ser usado como coadjuvante no tratamento do pterígio para prevenir recidivas.

Objetivo: Avaliar o efeito do tartarato de brimonidina a 0,2% tópico, instilado de 12/12 horas, na circulação retrobulbar em pacientes portadores de glaucoma. Métodos: Foram estudados os 2 olhos de 16 pacientes portadores de glaucoma primário de ângulo aberto e glaucoma crônico de ângulo estreito com iridotomia. Usando o Doppler colorido foram avaliados: velocidade sistólica máxima, velocidade diastólica final e índice de resistência das artéria central da retina, artéria ciliar posterior curta temporal e artéria oftálmica. As avaliações foram feitas antes e depois do uso da brimonidina. Resultados: O tartarato de brimonidina a 0,2% aumentou significativamente a velocidade sistólica máxima (28,24 para 34,23 cm/seg) e velocidade diastólica final (6,62 para 8,10 cm/seg) no olho direito e reduziu o índice de resistência (0,75 para 0,71) no olho esquerdo da artéria oftálmica. Conclusão: O tartarato de brimonidina 0,2% 2x/dia aumentou significativamente a velocidade sistólica máxima e velocidade diastólica final e reduziu índice de resistência da artéria oftálmica de pacientes glaucomatosos. Este efeito sugere que a brimonidina pode beneficiar pacientes glaucomatosos com insuficiência vascular na cabeça do nervo óptico.

Acute dacryocystitis retention (ADR) is an unusual entity that contributes to an incorrect diagnosis and treatment. We describe a case of acute dacryocystitis retention occurring in a 61-year-old diabetic male who presented with severe pain, swelling, and inflammatory signs above the left medial canthal ligament tendon. He had no previous history of epiphora. Computed tomography scan indicated acute dacryocystitis. Clinical treatment resulted in complete resolution of the condition. Syringing one month after the acute episode indicated a patent lacrimal excretory system. The temporary obstruction that evolved to an acute dacryocystitis retention was probably secondary to nasal alteration or supposed dacryoliths. Timely, conservative clinical treatment can lead to complete resolution of acute dacryocystitis retention with no further treatments.

OBJECTIVE: To report the outcomes and complications of colored soft contact lenses (SCLs) to improve esthetic or eye function in visually impaired (VI) or blind patients. METHODS: This retrospective study enrolled consecutive patients with unilateral or bilateral VI or blindness who had received colored SCLs to improve appearance or ocular function. Data were collected on demographics, complaints, complete ophthalmological examinations, types of SCL, follow-ups, and complications. RESULTS: The study sample was comprised of 109 patients (ages 4-80 years). Eighty-six patients (78.89%) had unilateral blindness, and 14 patients (12.84%) had functional disorder. Most of the patients presenting for improved esthetic had anterior segment pathology (74/67.88%), mainly secondary to trauma (55/50.5%) resulting in leukoma (73/66.97%). Patients with functional VI (19/17.43%) received filtered SCLs for color blindness (7/6.42%), diplopia (7/6.42%), or photophobia (5/4.58%). No serious complications were observed in any cases, and 94.49% of patients were satisfied with the SCLs. CONCLUSION: Colored SCLs can cover ocular surface imperfections in VI or blind eyes of patients who are seeking better cosmesis or improvement functional VI. Soft contact lenses with only one filter can cover imperfections of the ocular surface and improve vision in functional VI. Appropriate follow-up of these patients can reduce complication rates, resulting in good cosmesis and patient satisfaction with a positive impact on the lives of patients suffering from functional VI or blindness.

Purpose: To evaluate lower lid position and tear meniscus in peripheral idiopathic facial nerve palsy (FNP). Methods: A prospective study enrolled patients with peripheral idiopathic FNP and epiphora. Data were collected on patient demographics, House-Brackmann (HB) scale, digital photographs of the face, and tear meniscus at the 1st, 30, and 90 day after onset of FNP. Marginal reflex distance to the upper (MRD1) and lower eyelid (MRD2) were evaluated using ImageJ software. Anterior segment optical coherence tomography (OCT) was performed to measure the tear menis- cus. P<.05 was considered statistically significant. Results: Sixteen patients were evaluated. The HB scale at presentation was grade III in six patients (37.5%). At 90 day, nine patients (56.25%) were grade I-normal. Three (18.7%) had upper lid retraction, three (18.7%) upper eyelid asymmetry and 7 (43.75%), lower eyelid retraction. The difference between MRD2-FNP with MRD2-healthy side was 0.51 ± 1.9 mm at the 1st visit, decreasing to 0.09 ± 1.47 mm at 90 days (P=.877). Tear meniscus measurements were significantly higher in FNP at the 1st visit (P=.001). The decrease in MRD2 was statistically correlated with the reduction of the tear meniscus area (TMA) (r = 0.67; P=.007) at 90 days. No correlation was found between HB and TMA. There is a difference in TMA between age groups at the 1st day(p=.009). Eldest group had higher HB scales. Conclusion: Quantitative evaluation of eyelid position and tear meniscus are effective to document the evolution of FNP and can serve as a clue of orbicularis recovery.

Purpose To demonstrate that the steep peripheral ring (red zone) on corneal topography after myopic laser in situ keratomileusis (LASIK) could possibly due to instrument error and not always to a real increase in corneal curvature. Methods A spherical model for the corneal surface and modifying topography software was used to analyze the cause of an error due to instrument design. This study involved modification of the software of a commercially available topographer. Results A small modification of the topography image results in a red zone on the corneal topography color map. Conclusion Corneal modeling indicates that the red zone could be an artifact due to an instrument-induced error. The steep curvature changes after LASIK, signified by the red zone, could be also an error due to the plotting algorithms of the corneal topographer, besides a steep curvature change.

Purpose: To report indications and success rates of dacryocystectomy (DCT) in a tertiary hospital. Methods: A retrospective chart review was performed of all patients who underwent DCT at the King Khaled Eye Specialist Hospital, Saudi Arabia, from 2008 to 2015. Data included patient demographics, symptoms before and after surgery, and complications. Univariate analysis using parametric and non-parametric methods was performed. Results: Forty-seven DCT surgeries were performed over the study period. The median age of patients was 58.2 +/- 2 years old, 63.8% were female, 60% of surgeries were performed on the left side, and 8% of patients underwent bilateral simultaneous DCT. Chronic dacryocystitis was the surgical indication for DCT for all of the patients and 23.5% of them had dry eye preoperatively. Successful treatment was observed in 80.8% of patients and 8.5% complained of tearing after DCT. Conclusion: The main indication for DCT in our hospital was chronic dacryocystitis with good outcomes for elderly patients with dry eyes.

Purpose To evaluate the effect of mitomycin-C (MMC) on the success of external (Ex-DCR) or endoscopic dacryocystorhinostomy (En-DCR). Method A systematic review of randomized clinical trials of Ex- or En-DCR with and without the use of MMC to treat primary acquired nasolacrimal duct obstruction (NLDO) was done. Two authors independently searched six databases from 1990 to 2019, using the terms dacryocystorhinostomy and mitomycin-C. Statistical and meta-analyses were performed using RevMan 5.3 software. Results Twenty-seven studies involving 2158 surgeries were included in this systematic review. The Ex-DCR group comprised 14 studies [odds ratio (OR): 2.74; 95% confidence intervals (CI) 1.54-4.87; I-2 = 30%], while the En-DCR group 13 studies (OR: 1.69; 95% CI 1.21-2.37; I-2 = 0%). The use of MMC slightly increased the success rate of Ex- or En-DCR (OR: 2.1; 95% CI 1.52-2.9; I-2 = 14%). Conclusion The intraoperative use of MMC is safe and slightly improves the success rate of Ex- or En-DCR. However, the evidence was very weak.

ABSTRACT Purpose: This study aimed to evaluate the current practice patterns for assessing and managing upper lid ptosis among members of the Latin American and Spanish societies of Ophthalmic Plastic and Reconstructive Surgery. Methods: An e-mail was sent to invite members of both societies to participate in this anonymous web-based survey. The survey collected data on surgeons’ demographics and four other sections: upper lid ptosis preoperative evaluation, surgical preferences, postoperative management, and complications. The frequency and proportions of the responses were then statistically analyzed. Results: The survey was responded by 354 experienced oculoplastic surgeons, 47.7% of whom generally performed more than 20 upper lid ptosis surgeries annually. Of those respondents, 244 (68.9%) routinely check for dry eye preoperatively. Less than half of the respondents (47.4%) perform the phenylephrine test for congenital or acquired ptosis. Mild upper lid ptosis was reported to be usually corrected with conjunctival mullerectomy (43.6%). Severe upper lid ptosis was reported to be usually corrected with frontalis surgery (57%), followed by anterior levator resection, mainly supramaximal resection (17.5%). In cases of severe congenital ptosis, the main reason for surgery was to alleviate the risk of amblyopia (37.3%). An anterior approach was reported to be usually (63.3%) used to manage involutional ptosis associated with dermatochalasis. Common complications comprised undercorrection after levator resection (40%) or frontalis suspension (27.5%). Conclusions: This study reports the current practice patterns among Spanish and Latin American oculoplastic surgeons in upper lid ptosis diagnosis and treatment. Surgeons can use this study data to compare disease management with their colleagues.
