No history of any substance abuse.Īllergy history: No known drug allergies or any other allergies.įamily History: History of mother having high myopic glasses since childhood. Past Medical History/ History of Medication: No ophthalmic or systemic use of medication. Past Ocular History: High myopic using glasses She had no visual changes or symptoms in the left eye. No history of headache, ocular pain, redness, and trauma were reported. The patient is a 20-year-old female who presented with decreased vision in the right eye for 8 months. Research is being conducted to find a medical therapy to prevent and treat PVR, but to date, none has proven effective in most patients.Decreased vision in the right eye in a 20-year-old high myopic female History of Present Illness:
At the end of surgery, most patients with complex retinal detachment due to PVR or a giant retinal tear will receive a long-acting gas bubble or silicone oil filling into the vitreous cavity of the eye to hold the retina in position while the eye heals Your surgeon will decide which procedure is best depending on the nature of your detachment. Laser is also used in combination with the vitrectomy to seal the retinal breaks. Use of special retinal detachment repair strategies, including retinectomy or perfluorocarbon liquid, may be necessary in patients with complex retinal detachments. Patients may undergo pars plana vitrectomy with peeling of membranes, a scleral buckling procedure, or both. The only treatment option for complex retinal detachment is retinal surgery.

A fixed retinal fold (yellow arrow) is seen with a cone-shaped retinal detachment. B-scan ultrasound of a patient with PVR-related retinal detachment. To confirm whether there is subretinal fluid in the macula, optical coherence tomography (OCT) may be used.įigure 2. When view of the retina is obscured (blocked) by blood or dense cataract, B-scan ultrasonography can be used to determine the location and extent of a retinal detachment (Figure 2). Viewing the retina with an indirect ophthalmoscope while the doctor applies gentle pressure to the eye (scleral depression) is the primary method for diagnosing retinal detachment. Choroidal detachment-separation of the choroid from the sclera (the white of the eye).Vitreous hemorrhage-a leakage of blood into the gel that fills the eye cavity.Many risk factors for PVR have been identified, including: Retinal detachment with a giant retinal tear, however, is relatively uncommon. PVR is the most common cause of primary retinal detachment surgery failure, occurring in approximately 5% to 10% of all retinal detachments. PVR most commonly occurs after a previous (primary) retinal detachment repair surgery. Passage of liquefied vitreous gel through a retinal tear or hole results in an accumulation of fluid under the retina (subretinal fluid) and progression of the retinal detachment. The reason these membranes form is uncertain, but it is thought to be due to cells growing on the retinal surface. In the inferior macular with associated subretinal fluid. A patient with complex retinal detachment due to PVR in the left eye. When the detached retina contracts, so-called “star folds” often develop (Figure 1).įigure 1. Complex retinal detachments due to PVR are associated with retinal scar tissue or membranes these ultimately contract, pull, and stretch the retina, causing retinal tears or stretch holes.
