Objective: To describe a case of inflammatory pigment epithelial detachment (PED) presumed to be secondary to the amoeba Blastocystis hominis. Methods: This is an interventional case report. Results: A 46-year-old male complained of visual distortion in the left eye for 7 months. Examination revealed the presence of a subretinal cystic lesion on the fovea. Optical coherence tomography demonstrated a PED with a hyperreflective lesion over the detached retinal pigment epithelium (RPE). Work-up included a fecalysis, which revealed the presence of Blastocystis hominis. The patient was treated with oral metronidazole. RPE detachment resolved after treatment with no recurrence in 30 months of follow-up. Conclusion Intestinal parasitic infection may be associated with retinal disease and should be included in the differential diagnosis of PED when OCT reveals a hyperreflective lesion.

Objective: To present a case of neovascular glaucoma secondary to ocular ischemic syndrome following an uncomplicated phacoemulsification Methods: This is a case description of a 74-year-old male who developed blurred vision and increased intraocular pressure (IOP) two months after an uncomplicated phacoemulsification cataract surgery with posterior chamber lens implantation of the left eye. There was iris neovascularization with absence of retinal dot/blot hemorrhages or neovascularization. The fluorescein angiogram (FA) showed delayed choroidal fluorescence and arteriovenous time. IOP-lowering medications and intravitreal injection of aflibercept were given. Carotid doppler test showed 70% stenosis of the ipsilateral artery but a subsequent magnetic resonance angiography (MRA) did not show evidence of significant stenosis. Results: At his last consultation, visual acuity improved to counting fingers. IOP was maintained at 12 mmHg with one anti-glaucoma medication. Conclusion Ocular ischemia can confound the outcome of an uncomplicated cataract surgery. Doppler scans are usually chosen as the first-line exam for those suspected of carotid stenosis but, at times, may have contradictory results with MRA.

Objective: To report the efficacy and safety of intravitreal pegaptanib sodium (IVP) on macular edema (ME) due to branch retinal-vein occlusion (BRVO) among patients intolerant to intravitreal triamcinolone acetonide (IVTA). Methods: Four eyes with ME due to BRVO were included in this interventional case series. The main outcome measures were best-corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure (IOP), and adverse effects. Results: There was a significant decrease in mean CMT from 524.50 ± 141.12 to 293.75 ± 130.75 microns (p = 0.009) after IVP injection. BCVA improved in all 4 eyes after IVP. Mean IOP after IVP was 13.60 ± 3.21. No ocular or systemic complications were observed. Conclusion IVP appears to be safe and effective in decreasing retinal thickness and improving VA in eyes with ME due to BRVO. IVP is a potential treatment for eyes that are intolerant to IVTA.
