background: onchocerciasis is endemic in the imo river basin, nigeria. this study was aimed at assess­ing the prevalence and intensity of microfilaria of onchocerca volvulus in the area. methods: a cross-sectional study was carried out in the okigwe local government area, imo state, nige­ria. two skin snips (one from the waist and another from the shoulder) were taken from 1024 individu­als exa...

Background: Scleromalacia, in the form of scleral thinning, melting, and necrosis, is a potentially serious complication of pterygium excision. This study introduces a new biodegradable material, OlogenTM collagen matrix (OCM), to repair scleral thinning as an alternative to preserved scleral tissue, and evaluates the long-term outcomes of OCM for ocular surface reconstruction surgery. Case pre...

purpose : to assess the efficacy and safety of sutureless punch trabeculectomy as substitute for conventional scleral flap trabeculectomy. methods : in a prospective, randomized study, 44 eyes of 42 patients with primary open angle glaucoma (poag) who were candidate of trabeculectomy were included and randomly assigned into two groups sutureless punch trabeculectomy or conventional scleral flap...

BACKGROUND This study analyzes the characteristics of donor and recipient tissue preparation between the Hessburg-Barron and Hanna punch and trephine systems by using elliptical curve fitting models, light microscopy, and anterior segment optical coherence tomography (AS-OCT). METHODS Eight millimeter Hessburg-Barron and Hanna vacuum trephines and punches were used on six cadaver globes and s...

BACKGROUND The use of conventional foldable hydrophobic intraocular lenses (IOLs) in microincision cataract surgery (MICS) currently requires wound enlargement. We describe a combined surgical technique of MICS and trabeculectomy with insertion of a foldable IOL through the trabeculectomy fistula. METHODS After completion of MICS through two side port incisions, a 3.2 mm keratome is used to e...

optical rehabilitation of the patient with aphakia who cannot tolerate contact lenses present a therapeutic challenge. in the absence of capsular support, anterior chamber lenses have been widely used. on the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. the purpose of t...

A 20-year-old girl presented with a one-week history of fever and chills, malaise, generalized erythema (including the face, trunk, back and extremities), edema (initially the face and then lower limbs) and hoarseness (Figure 1). Physical examination revealed low-grade fever, jaundice, lymphadenopathy (posterior cervical, submandibular, <1 cm, no axillary, no inguinal). Dermatological exa...

Pre-existing scleral pathology is an important risk factor for globe rupture during scleral buckling procedures. We report here, the surgical management of an unexpected scleral pathology found at the scleral buckling procedure in a retinal detachment patient. A 77-year-old white female with retinal detachment underwent a scleral buckling procedure. The surgery was converted into a scleral graf...

BACKGROUND Punch instrument is a circular blade that can be used for many diagnostic and therapeutic purposes in different medical and surgical specialties. Punch surgery (or biopsy) is achieved by using this versatile punch blade under local anesthesia. Basic punch surgery is quick and easy to learn. Complications such as bleeding and infection are minimal. Diagnostic punch surgery can obtain ...
