PO-RET-134<br />

Acute Retinal Necrosis After Boston Type I Keratoprosthesis (Case<br />

Report)<br />

Al Rashaed Saba (1) , Alamri, MD Abdullah (1) , Al Kharashi, MD Sulaiman (1)<br />

1. King Khaled Eye Specialist Hospital<br />

Objective: To demonstrate the safety and efficacy <strong>of</strong> prechopping with only two<br />

viscoelastic cannulas avoiding the need <strong>of</strong> complimenary instrumentation.<br />

Methods: Two randomized groups were operated <strong>of</strong> cataract surgery by a<br />

single surgeon. One group (control) was operated with traditional in the bag<br />

prechopping with prechop forceps, while the experimental group was operated<br />

with prechopping with viscoelastic cannulas at the iris plane. Surgical variables<br />

and postoperative outcomes were recorded in both gropups.<br />

Results: No differences were found between the groups regarding surgical<br />

complications and postoperative outcome. Only statistical difference was found<br />

in the lesion to the capsular bag, maybe because the precopping maneuvers<br />

within; the group with prechopping with cannulas at the iris plane, showed less<br />

incidence <strong>of</strong> capsular bag damage.<br />

Conclusion: Prechop with viscoelastic cannulas at the iris plane is a safe and<br />

effective technique. It is also unexpensive.,<br />

Idiopathic Polypoidal Choroidal Vasculopathy in a Young Man<br />

Al Rashaed Saba (1)<br />

1. King Khaled Eye Specialist Hospital<br />

Purpose: To report a case <strong>of</strong> idiopathic polypoidal choroidal vasculopathy and<br />

its angiographic characteristics in a young man. Method: Clinical data including<br />

visual acuity, color fundus photography, uorescein angiograph and indocyanine<br />

green results <strong>of</strong> this case were reviewed. Case: A 21-year-old Saudi healthy<br />

man presented with sudden loss <strong>of</strong> vision in the left eye for 3 weeks duration.<br />

Visual acuity in the right eye was 20/20 and in the left eye was 1/200. Fundus<br />

examination <strong>of</strong> right eye was normal; however, in the left eye showed vitreous<br />

hemorrhage with massive sub retinal yellowish old blood in the posterior pole<br />

with epiretinal fresh blood on the fovea. Intra venous uorescein angiography<br />

and indocyanine green tests showed features <strong>of</strong> idiopathic polypoidal choroidal<br />

vasculopathy. Patient received photodynamic therapy twice without signicant<br />

visual improvement.<br />

Conclusion: Idiopathic polypoidal choroidal vasculopathy can occur in a young<br />

age group and can lead to severe visual impairment. Key words: Idiopathic<br />

polypoidal choroidal vasculopathy, young age, severe visual loss, photodynamic<br />

therapy<br />

Characteristics <strong>of</strong> Optic Disc Melanocytomas Presenting with Visual<br />

Dysfunction<br />

Al Rashaed Saba (1) , Nowilaty Sawsan (1) , Abboud Emad (1)<br />

1. King Khaled Eye Specialist Hospital<br />

Objective and Design: A retrospective review study was designed to describe<br />

five cases <strong>of</strong> optic disc melanocytomas with tumor-related visual impairment.<br />

Participants: Five patients with optic disc melanocytoma presented with visual<br />

complaints to a tertiary eye hospital in Saudi Arabia. Materials and<br />

Methods: Demographic and clinical data were analyzed, including the results<br />

<strong>of</strong> ocular examination, lesion laterality, best-corrected Snellen visual acuity,<br />

pupillary reflex, visual field testing, color fundus photography, fundus<br />

fluorescein angiography, and ophthalmic ultrasound.<br />

Results: Visual dysfunction secondary to optic disc melanocytoma was<br />

identified. Case 1 had macular star edema with mild tumor enlargement,<br />

Case 2 had optic atrophy, Case 3 had juxtapapillary choroidal neovascular<br />

membrane with macular involvement, Case 4 had optic disc swelling with an<br />

enlarged blind spot, and Case 5 had a large altitudinal visual field defect.<br />

Conclusion: Although melanocytomas <strong>of</strong> the optic disc tend to have a benign<br />

behavior with slow evolution and stable vision, they may adversely affect visual<br />

function through a variety <strong>of</strong> mechanisms.<br />

Combined Intravitreal Bevacizumab with Photodynamic Therapy<br />

Followed by a Tailored Re-treatment in Polypoidal Choroidal<br />

Vasculopathy; Three-Year Results<br />

1. Seoul Saint Mary›s Hospital<br />

PURPOSE: To evaluate the efficacy <strong>of</strong> initial combination therapy using<br />

photodynamic therapy (PDT) and intravitreal bevacizumab (IVB), followed by a<br />

tailored treatment for recurrent lesions.<br />

Methods: Forty eyes <strong>of</strong> 38 patients were retrospectively reviewed. When<br />

treating recurrent lesions, selective PDT and/or laser combined with IVB were<br />

performed for polyps. Bevacizumab was given when there was no certain<br />

polyp.<br />

Results: The recurrent rates were 42.5%. The mean numbers <strong>of</strong> PDT, laser,<br />

and IVB were 1.65, 0.1, and 5.93 respectively. The mean BCVA was 0.67<br />

logMAR at baseline and 0.55 at 3 years.<br />

Conclusions: This treatment strategy showed promising visual outcome, while<br />

reducing PDT number.<br />

Bevacizumab for serous changes originating From a Persistent<br />

Branching Vascular Network After Following Photodynamic Therapy<br />

for Polypoidal Choroidal Vasculopathy<br />

1. Seoul Saint Mary›s Hospital<br />

Purpose: To report the efficacy <strong>of</strong> intravitreal bevacizumab for recurrent or<br />

persistent serous changes originating from a persistent branching vascular<br />

network or secondary choroidal neovascularization after photodynamic therapy<br />

for polypoidal choroidal vasculopathy, despite regression <strong>of</strong> polypoidal lesions.<br />

Methods: Twenty eyes <strong>of</strong> twenty patients with at least 12 months <strong>of</strong> regular<br />

follow-up were retrospectively reviewed. Intravitreal bevacizumab was<br />

administered on an as-needed basis, guided by optical coherence tomography<br />

(OCT), after the first injection.<br />

Results: Seventeen (85%) <strong>of</strong> 20 eyes showed resolution <strong>of</strong> macular fluid after<br />

a mean <strong>of</strong> 1.9 (range 1-3) consecutive injections; however, fifteen (88%) <strong>of</strong> them<br />

had relapsing episode(s) <strong>of</strong> fluid collection. The mean number <strong>of</strong> injections<br />

needed were 4.2 (range 1-6) over a period <strong>of</strong> 12 months. At 12 months, 10<br />

eyes (50%) had no fluid accumulation on OCT, while 10 eyes (50%) had some<br />

residual fluid. The mean central foveal thickness improved significantly from<br />

280±37 ?to 226±62 ? (P=0.002). Visual acuity was maintained or improved in<br />

16 eyes (80%).<br />

Conclusions: Intravitreal bevacizumab appears to be effective in resolving<br />

intraretinal or and subretinal fluid originating from these lesions. However, the<br />

favorable effect was maintained for only a limited period <strong>of</strong> time and required<br />

repeated injections.<br />
