  • Repair of Open Globe Injury
    Advances in Ophthalmology & Visual System Case Report Open Access Case report: repair of open globe injury Abstract Volume 3 Issue 1 - 2015 Globe rupture is a common sight-threatening ophthalmic emergency. We present a twelve-year-old girl with ocular trauma by sharp object resulting in corneal laceration, Nader Hussein Fouad Hassan Department of Ophthalmology, Benha University Hospital, hyphema, traumatic cataract and iris prolapse. This case illustrates the importance of early Egypt diagnosis, proper wound repair of ruptured globe as well as management of post-operative complications and value of early post-operative visual rehabilitation. Correspondence: Nader Hussein Fouad Hassan, Ophthalmology department, Benha University Hospital, Keywords: globe rupture, open globe injury, corneal laceration Kaliyobeya, Egypt, Tel +201224727982, Email Received: October 16, 2015 | Published: October 19, 2015 Abbreviations: FB, foreign body; VA, visual acuity; CT scan, patient then was given tetanus immunization, antiemetics, analgesics computerized tomography; RD, retinal detachment; INR, international and intravenous broad spectrum antibiotics and prepared for globe normalized ratio; GA, general anesthesia; D, diopter rupture repair under GA. Laboratory tests included a full blood count, liver function tests, INR, prothrombin time, partial thromboplastin Introduction time, kidney function tests, all were within normal. Ruptured Globe is a common ophthalmic emergency. It is a leading cause of blindness. Early examination with high level of suspicion is recommended in any patient with ocular trauma. Many signs may obscure detection of globe rupture, so the ophthalmologist should examine the patient thoroughly and treat the patient as early as impossible including early visual rehabilitation for young patients to prevent amblyopia. Globe rupture may be associated with traumatic hyphema, traumatic cataract, lens dislocation, vitreous hemorrhage, retinal detachment, uveal prolapse, scleral wound, orbital wall fractures, or optic nerve damage.

Abstract Purpose: To report a case of acute keratoconus-like corneal hydrops in a patient with long-term ocular massage following trabeculectomy. Methods: Case report and review of medical literature. Results: A rare complication of acute keratoconus-like corneal hydrops occurred in a patient following the use of ocular massage to maintain satisfactory aqueous humor filtration after trabeculectomy. The patient had a history of high myopia but denied previous ocular trauma, allergic disease and a family history of keratoconus. Slit-lamp examination demonstrated keratoconus-like corneal hydrops with formation of epithelial microcystic, and intrastromal cleft.

  • CAUSES, COMPLICATIONS &TREATMENT of A“RED EYE”
    CAUSES, COMPLICATIONS & TREATMENT of a “RED EYE” 8 Most cases of “red eye” seen in general practice are likely to be conjunctivitis or a superficial corneal injury, however, red eye can also indicate a serious eye condition such as acute angle glaucoma, iritis, keratitis or scleritis. Features such as significant pain, photophobia, reduced visual acuity and a unilateral presentation are “red flags” that a sight-threatening condition may be present. In the absence of specialised eye examination equipment, such as a slit lamp, General Practitioners must rely on identifying these key features to know which patients require referral to an Ophthalmologist for further assessment. Is it conjunctivitis or is it something more Iritis is also known as anterior uveitis; posterior uveitis is serious? inflammation of the choroid (choroiditis). Complications include glaucoma, cataract and macular oedema. The most likely cause of a red eye in patients who present to 4. Scleritis is inflammation of the sclera.

It also encompasses surgery first performed centuries ago, such as rudimentary pterygium excision, to the latest in keratorefractive surgery. CATARACT EXTRACTION AND INTRAOCULAR LENS IMPLANTATION The many reasons for the development of cataracts are discussed in detail in Chapter 8. Most cataracts are acquired, but they can also be congenital. This section focuses primarily on the treatment of acquired cataracts in adults. Cataracts in adults are generally age related, but some lens opacities may result from other causes such as trauma, inflammation, systemic illness such as diabetes, or medications such as corticosteroids. Cataracts generally advance slowly over years but can advance rapidly over months, or even faster in some patients. The primary indication for cataract extraction is diminished vision caused by the cataract, significantly affecting the patient's lifestyle. The exact point at which this hardship occurs depends on the patient. Certain patients require little visual function and may delay cataract surgery for years or indefinitely. Other patients with high visual needs seek cataract surgery with much smaller degrees of visual loss.

    Original Article Role of Temporary Tarsorrhaphy Using Super Glue in the Management of Corneal Disorders Muhammad Moin, Irfan Qayyum, Anwar Ul-Haq Ahmad, Mumtaz Hussain Pak J Ophthalmol 2009, Vol. 25 No. 3 . .. .. See end of article for Purpose: To evaluate the safety and efficacy of temporary tarsorrhaphy using authors affiliations super glue in the management of corneal disorders. … ……………………… Material and Methods: A retrospective chart review of 46 consecutive patients who underwent superglue tarsorrhaphy from June 1997 to June 1998 was Correspondence to: performed. All patients were managed at the Institute of Ophthalmology, Mayo Mohammad Moin hospital, Lahore. This study included patients with painful non healing corneal Department of Ophthalmology ulcers, exposure keratopathy (secondary to moderate proptosis), dry eyes (to Mayo Hospital reduce surface area of evaporation) and post-operative patients with conjunctival Lahore flaps ± scleral grafts (to help take up of the graft). Patients with corneal perforations, endopthalmitis or panophthalmitis were excluded from the study. Temporary tarsorrhaphy was done using super glue technique in which the upper eyelashes were glued to the lower lid skin. The degree of lid closure was calculated according to the pre-existing corneal pathology. Patients were followed up on a weekly basis for one month to check for reduction of pain, improvement of corneal pathology and duration of tarsorrhaphy. Results: There were 50 eyes of 46 patients included in the study who underwent super glue tarsorrhaphy for various corneal pathologies. There were 36 males and 10 female patients with an average age of 40 years (range 10-60 yrs). Thirty two eyes had keratitis (fungal, bacterial, disciform, dendritic), 5 had a persistent epithelial defect, 4 had exposure keratopathy secondary to moderate proptosis, 5 had conjunctival flap alone or combined with a scleral graft and 4 had dry eyes.
