Traumatic Hyphema: a Teaching Case Report Introduction he following case report is to be used as a teaching guide appropriate for third- and T fourth-year optometry stu- dents as well as optometry residents. The case report describes a patient with hyphema as a result of closed-globe in- jury who develops a number of associ- ated sequelae of blunt force trauma to include increased intraocular pressure, vitreous hemorrhage and angle reces- sion with iridodialysis.

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.

  • Intraocular Pressure During Phacoemulsification
    J CATARACT REFRACT SURG - VOL 32, FEBRUARY 2006 Intraocular pressure during phacoemulsification Christopher Khng, MD, Mark Packer, MD, I. Howard Fine, MD, Richard S. Hoffman, MD, Fernando B. Moreira, MD PURPOSE: To assess changes in intraocular pressure (IOP) during standard coaxial or bimanual micro- incision phacoemulsification. SETTING: Oregon Eye Center, Eugene, Oregon, USA. METHODS: Bimanual microincision phacoemulsification (microphaco) was performed in 3 cadaver eyes, and standard coaxial phacoemulsification was performed in 1 cadaver eye. A pressure transducer placed in the vitreous cavity recorded IOP at 100 readings per second. The phacoemulsification pro- cedure was broken down into 8 stages, and mean IOP was calculated across each stage. Intraocular pressure was measured during bimanual microphaco through 2 different incision sizes and with and without the Cruise Control (Staar Surgical) connected to the aspiration line. RESULTS: Intraocular pressure exceeded 60 mm Hg (retinal perfusion pressure) during both standard coaxial and bimanual microphaco procedures. The highest IOP occurred during hydrodissection, oph- thalmic viscosurgical device injection, and intraocular lens insertion. For the 8 stages of the phaco- emulsification procedure delineated in this study, IOP was lower for at least 1 of the bimanual microphaco eyes compared with the standard coaxial phaco eye in 4 of the stages (hydro steps, nu- clear disassembly, irritation/aspiration, anterior chamber reformation). CONCLUSION: There was no consistent difference in IOP between the bimanual microphaco eyes and the eye that had standard coaxial phacoemulsification. Bimanual microincision phacoemul- sification appears to be as safe as standard small incision phacoemulsification with regard to IOP.
