ABSTRACT Objective Compare the thickness of conjunctival autografts in pterygium surgery using the Moscovici dissection technique with manual dissection and assess the difficulty of the techniques. Methods In this randomized clinical trial, 30 eyes of 30 patients undergoing pterygium surgery were divided into the Moscovici Dissection Technique Group and the Manual Dissection Group. The patients were treated at the Hospital Oftalmológico Visão Laser (Santos, São Paulo, Brazil). Optical coherence tomography was performed to measure graft thickness three months postoperatively. Three […]

ABSTRACT Objective: To describe results of pterygium surgery at Clínica de Cirurgía Ocular Villavicencio, in Meta, Colombia. Methods: A retrospective analysis of pterygium surgeries performed between January 2017 and December 2019. Results: Approximately 1,200 records were reviewed, and 1,200 procedures included. The most frequent complications were corneal Dellen, pterygium recurrence, graft retraction and pyogenic granuloma (7.5%, 2.5%, 3% and 0.75% respectively). These were identified within the first 6 months of surgery. Conclusion: Pterygium surgery using conjunctival autografts is an effective […]

ABSTRACT This paper aimed to report a case of tarsal buckling associated with conjunctival prolapse and upper eyelid inversion as a complication of surgical correction of residual ptosis. A 15-year-old female patient with unilateral residual eyelid ptosis in the right eye, secondary to partial correction of congenital blepharoptosis operated in childhood. The second surgery was performed with resection of the upper eyelid levator muscle aponeurosis, which progressed to conjunctival inversion of the upper eyelid. The structural fragility of the tarsus […]

ABSTRACT Amyloidosis is characterized by extracellular deposition of protein amyloid fibrils in tissues, including conjunctiva, which are insoluble in proteolytic proteins. Conjunctival amyloidosis specifically in the palpebral conjunctiva is a rare finding in clinical practice. The authors described the case of a 71-year-old caucasian male patient, with bilateral lesions located in the lower eyelid conjunctiva, elevated, well-defined, yellowish, combined with destabilized eyelids. Surgical excision of the lesions was performed, and the histological examination confirmed conjunctival amyloidosis. There was no recurrence […]

ABSTRACT Objective: To describe ocular surface findings in impression cytology obtained from healthy rabbit conjunctiva treated with interferon alpha-2b eyedrop, and compare them to findings after use of mitomycin C 0.02%. Methods: An experimental study using a rabbit model was performed between September 2013 and October 2014 at the Faculdade de Medicina de Marília, Universidade Federal de São Paulo, Clínica de Olhos Moacir Cunha. Thirty New Zealand white rabbits were divided into 6 groups and received interferon alpha-2b or mitomycin […]

The present report reports a case of conjunctivitis caused by Ralstonia pichettii in an immunocompetent patient wearing a contact lens. The bacterium isolated from the solution used to disinfect R. pichettii does not belong to the human microbiota but infects immunodepressed patients and is present in aqueous solutions. There is no standardization of sensitivity for this bacterium and few antibiotics have been tested for non-fermenting glucose bacteria. Due to the reduced antimicrobial sensitivity profile demonstrated by R. pichettii, it is […]

Introduction: Pterygium is a centripetal proliferation of fibrovascular tissue, which proceeds from the bulbar conjunctiva towards the center of the cornea. Excision of the pterygium may cause visual acuity improvement and surgical excision aims to achieve a topographically regular ocular surface. The improvement of the visual acuity results from the alteration of the refractive corneal power, that is measured in the topography as alteration of the topographic astigmatism. The objective of this study was to evaluate the variation of the […]

Objective: To evaluate acute eye irritation in rabbits following topical administration of essential oil. Methods: animals were divided into three groups, each containing three rabbits, with a total of 6 eyes per group. The difference between them was the concentration used (1, 3 and 9%). A single dose of 0.1 ml of the product was applied into the conjunctival sac of one eye of the animal, and the contralateral eye was used as control. The effects caused by the essential […]
