ABSTRACT
@#AIM: To investigate the clinical effect of autologous penetrating keratoplasty in the treatment of corneal blindness. <p>METHODS: Totally 8 patients with corneal blindness were treated by autologous penetrating keratoplasty in our hospital from 2014-01 to 2018-03. Using retrospective analysis, the patients were followed up for one year. To observe the intraoperative complications and postoperative conditions such as visual acuity, corneal transparency, and other were observed.<p>RESULTS: The uncorrected visual acuity of all the 8 patients was greater than 0.02 1wk after operation, and the rate of restoration of visual acuity was 100%(8/8). The corrected visual acuity of 5 patients(5-8)was more than 0.3 1mo after operation. The corrected visual acuity of 3 patients(3-8)with severe cataract before operation was improved to 0.08-0.2. One year later, all the corneal grafts in the recipient eyes were transparency and no recurrence of infection or secondary infection occurred in all 8 patients. <p>CONCLUSION: Corneal graft is easy to grow and there are no exclusion reactions, fewer postoperative complications after autologous corneal transplantation. So, corneal implants can remain transparent for a long time, and the surgery cost is lower. Autologous corneal transplantation can not only provide long-term useful vision for patients with monocular blindness combined with corneal blindness, but also reduce their financial burden and bring great benefits to patients.
ABSTRACT
RESUMO O surgimento de uma membrana fibrótica opacificada na córnea transplantada é pouco descrito nas literaturas nacional e mundial. O objetivo é relatar o caso de um paciente com leucoma total de olho esquerdo que foi submetido à ceratoplastia penetrante levando a formação de dupla câmara anterior devido ao surgimento de uma membrana fibrótica cicatricial. Paciente do sexo masculino, 54 anos, com leucoma total secundário a ceratite herpética, diabético há 20 anos, em uso de insulina, com retinopatia diabética não proliferativa. Realizou-se cirurgia de membranectomia com complicações pós-operatória.

AlM: To evaluate the therapeutic effects and safety of femtosecond laser assisted penetrating keratoplasty ( FS-PKP) . METHODS: ln the retrospective case series study, 46 cases ( 48 eyes ) with FS- PKP holds were analyzed. Preoperative best corrected visual acuity ( BCVA) was 2. 35 ± 1.01 (with a standard logarithmic eye chart). Opacities were all from epithelium to endothelium, including keratoconus, keratolukoma and corneal scarring etc. The full-thickness corneal donor-recipient grafts in different diameter and incision kerfangle were made by femtosecond laser in keratoplasty. The patients were treated according to the conventional penetrating keratoplasty after surgery. Evaluation indexes included preoperative and postoperative 1, 6, 10mo uncorrected visual acuity (UCVA), BCVA, corneal astigmatism (CA) and surgical complications. Forty-three cases (44 eyes) with traditional PKP were as control group. The data of two groups were analyzed by mean comparison of two groups and Chi-square test in SPSS 18. 0. RESULTS: All the operations were completed successfully, postoperative visual acuity of all patients had different degrees of increase. Comparison with the postoperative UCVA of traditional PKP surgery, UCVA was 3. 48 ± 0. 43 and 2. 97 ± 1. 14 at 1mo after operation, respectively, with statistically significant difference ( P=0. 009). The UCVA was 3. 86±0. 25 and 3. 74±0. 73 at 3mo after operation, respectively; the UCVA was 4. 04 ± 0. 23 and 3. 98 ± 0. 29 at 6mo after operation, respectively, with no statistically significant difference (P=0. 146, P=0. 56). ln FS-PKP group, BCVA was better than traditional PKP surgery group, with statistically significant difference ( P=0. 002 ). While there had no statistically significant difference between two groups of BCVA at 6, 10mo after operation (P6mo =0. 132, P10mo =0. 47). The incidence of complication of FS-PKP surgery, such as postoperative astigmatism, postoperative intraocular pressure and postoperative incision dehiscence were significantly lower than the one of traditional PKP surgery(P CONCLUSlON:Compared with traditional penetrating keratoplasty, FS-PKP provides significantly faster visual recovery in the early postoperative period, and induces significantly less corneal astigmatism and lower incidence of complication. lt reflected the clinical superiority of this new technology .
ABSTRACT
Purpose: To investigate and describe the ophthalmic contribution of Raja Serfoji II (1798-1832). Materials and Method: A team of 2 ophthalmologists, director of laboratory services, one archeologist and a photographer visited Sarasvathi Mahal Library, March 2004. Photographs of ophthalmic records were taken and analysed. An interview of the present prince, S Babaji Rajah Bhonsle was taken. Ophthalmologic case sheets of 44 patients, 18 pictures were found. Results: Forty-four patient's ophthalmic records were found. Six records were written in Modi script, 38 were written in English and 18 drawings were found. Conclusion: In Thanjavur, King Serfoji II carried out methodical ophthalmic practices between 1798 and 1832. Both European and Indian medicines were used. Cataract Surgery was performed. Detailed ophthalmic records were maintained. The only evidence of Serfoji's amazing contribution to medicine lies in 50 charts and manuscripts.
ABSTRACT
The availability of data sets covering more than a year is scarce for tropical environments. Advances in hardware and software speed-up the re-analysis of old data sets and facilitates the identification of hidden data patterns. From February 1984 to April 1987 (49 sampling dates), core samples (17.7cm², 15cm deep) were collected at low tide at a sand-mud flat in the mid upper Gulf of Nicoya estuary, Pacific, Costa Rica. Predator exclusion experiments (cages 0.5x0.5x0.2m, galvanized wire, mesh size 5mm), were conducted at the site in 1985 (dry and rainy seasons sets). Samples were preserved with 5% buffered formalin in sea water stained with Rose Bengal, and washed after 24 hours on a 500 micron mesh sieve. The 1 120 cores yielded a total of 112 morphological species of which the mollusks were represented by 23 species, and included the bivalves Tellina rubescens, Tagelus bourgeoisae, Dosinia dunkeri and Leukoma asperrima, and the gastropods, Natica unifasciata, Nassarius luteostomus, Costoanachis rugosa and Turbonilla sp. The 23 species are indicative of a relatively rich sedimentary molluscan fauna. T. bourgeoisae had a seasonal oscillation, with higher abundancesduring the rainy seasons. T. rubescens was not seasonal, but presented an oscillation with peaks at about 1.5 year intervals. Many empty shells of Cosmioconcha modesta, lower number of N. luteostomus and a few of T. rubescens were found with boreholes by the predatory snail N. unifasciata. T. rubescens was not significantly more abundant inside or outside cages. T. bourgeoisae showed a significant increase within the caged areas. The numerical fluctuations of the mollusks became more important during the rainy season of 1985. Red tide outbreaks in the Gulf of Nicoya in 1985 may have had an impact on the molluscan populations.

La disponibilidad de datos con una cobertura mayor al año es rara para ambientes tropicales. Avances en computación y programas de cómputo facilitan el re-análisis de antiguos datos y la identificación de patrones ocultos en ellos. desde febrero de 1984 hasta abril de 1987 (49 fechas de colecta), muestras de barreno (17.7cm², 15cm de profundidad) fueron recolectadas durante la marea baja en una planicie arenosa-fangosa en la región media del estuario del Golfo de Nicoya, Costa Rica. Experimentos de exclusión de depredadores (jaulas 0.5x0.5x0.2m, malla galvanizada, poro de 5mm), fueron realizados en el sitio en 1985 (estación seca vs estación lluviosa). Las muestras fueron preservadas con formalina al 5% en agua de mar teñida con Rosa de Bengala y lavadas después de 24 horas en un tamiz de 500 micras de poro de malla. Los 1 120 barrenos produjeron un total de 112 especie morfológicas, de las cuales los moluscos estuvieron representados por 23 especies que incluyen los bivalvos: Tellina rubescens, Tagelus bourgeoisae, Dosinia dunkeri y Leukoma asperrima, y los gastrópodos, Natica unifasciata, Nassarius luteostomus, Costoanachis rugosa y Turbonilla sp. Las 23 especies son indicadoras de una fauna de moluscos relativamente rica. T. bourgeoisae presentó una oscilación estacional, con mayor abundancia durante la estación de lluvias. T. rubescens no fue estacional, pero presentó una oscilación con máximos a intervalos de cerca de 1.5 años. Muchas conchas vacías de Cosmioconcha modesta, un poco menos de N. luteostomus y unas pocas de T. rubescens fueron encontradas con perforaciones hechas por el depredador N. unifasciata. T. rubescens no fue significativamente más abundande dentro o fuera de las jaulas. T. bourgeoisae mostró una falta de abundancia estacional, pero una densidad significativamente mayor dentro de las jaulas. Las fluctuaciones poblacionales de los moluscos fueron más importantes durante la estación de lluvias cuando se les compara con las fluctuaciones de los poliquetos, crustáceos y otros grupos. Mareas rojas en el Golfo de Nicoya durante 1985 podrían haber tenido un impacto en la dinámica de las poblaciones de moluscos.

PURPOSE: To describe etiologies and clinical characteristics of corneal opacities leading patients to seek cosmetic treatments. METHODS: The medical records of 401 patients who presented for cosmetic improvement in corneal opacities between May 2004 and July 2007 were retrospectively reviewed. The following parameters were analyzed: age, gender, cause of corneal opacity, time course of the corneal disease, associated diseases, prior and current cosmetic treatments, visual acuity, location and depth of the corneal opacity, and the presence of either corneal neovascularization or band keratopathy. A single practitioner examined all patients. RESULTS: The most common causes of corneal opacity were ocular trauma (203 eyes, 50.6%), retinal disease (62 eyes, 15.5%), measles (38 eyes, 9.5%), and congenital etiologies (22 eyes, 5.5%). Prior treatments included iris colored contact lenses (125 eyes, 31.1%) and corneal tattooing (34 eyes, 8.46%). A total of 321 of 401 eyes underwent cosmetic treatment for corneal opacities. The most common treatment performed after the primary visit was corneal tattooing (261 eyes, 64.92%). CONCLUSIONS: This is the first study to investigate the causes and clinical characteristics of patients presenting for cosmetic treatment of corneal opacities rather than for functional improvement. Various cosmetic interventions are available for patients with corneal opacities, and these should be individualized for the needs of each patient.
