Outcomes of pars plana vitrectomy with subretinal tissue plasminogen activator injection and pneumatic displacement of fovea-involving submacular haemorrhage.

OBJECTIVE: Fovea-involving subretinal haemorrhage is challenging to manage with uncertain visual outcomes. We reviewed outcomes of patients with fovea-involving macular haemorrhage treated with pars plana vitrectomy (PPV) and subretinal tissue plasminogen activator (tPA) with pneumatic displacement. METHODS AND ANALYSIS: This is a retrospective interventional case series. All patients with submacular haemorrhage who underwent PPV with subretinal tPA injection were included. Reasons for exclusion encompassed patients who underwent intravitreal tPA injection in the office without surgery, insufficient follow-up or documentation. Primary outcomes of interest were postoperative visual acuity (VA) at month 1 and 3. Secondary outcomes were median VA at month 3 by location of haemorrhage and underlying diagnosis. RESULTS: Thirty-seven total patients were included. The mean age was 68.2 years, with 54.1% (20/37) females. The most common aetiology was exudative macular degeneration (43.2%), followed by undifferentiated choroidal neovascularisation (CNV) (18.9%), polypoidal choroidal vasculopathy (18.9%), traumatic CNV (10.8%), macroaneurysm (5.4%) and proliferative diabetic retinopathy (2.7%). Median preoperative VA was 20/2000, postoperative month 1 was 20/347 (p<0.01), improving to 20/152 (p<0.01) at month 3. Proportion of patients gaining vision 3+ lines in vision was 15/36 (42%). Mean preoperative central subfield thickness on optical coherence tomography was 512.2 µm for sub-retinal pigment epithelium haemorrhage and 648.2 µm for subretinal haemorrhage (p=0.48). Difference in VA by diagnosis was not significant (p=0.60). CONCLUSIONS: PPV with subretinal tPA injection and pneumatic displacement of submacular haemorrhage offers modest visual recovery for a diverse group of patients. Location of haemorrhage or specific diagnosis may not predict outcome.

Endophthalmitis Associated With Glaucoma Drainage Implants.

BACKGROUND AND OBJECTIVE: To identify the clinical features, organisms, and treatment outcomes in patients with endophthalmitis associated with glaucoma drainage implants. PATIENTS AND METHODS: A retrospective noncomparative case series. RESULTS: Of the 13 patients, exposure occurred in eight eyes, including exposure of the tube in four eyes, exposure of the patch graft in three eyes, and exposure of the plate in one eye. In the remaining five eyes, either recent implant placement or conjunctival revision occurred. The most common organism was Staphylococcus epidermidis (five eyes). Intravitreal antibiotics were administered in all eyes, with the exception of one eye (primary evisceration). Removal of the implant was performed in six eyes and evisceration or enucleation was performed in three eyes. Median pre-infection visual acuity was 20/80 (range: 20/30 to hand motion). Visual acuity at last follow-up was no light perception (five eyes), light perception (two eyes), hand motion (one eye), and better than or equal to 20/200 (five eyes). CONCLUSION: Clinical features associated with endophthalmitis include implant exposure and a history of recent surgery. Staphylococcus epidermidis was the most common isolate. Although removal of the implant was performed in many patients, successful treatment was accomplished in some patients without removal. Visual outcomes were generally poor.

One-year results and anterior segment optical coherence tomography findings of descemet stripping automated endothelial keratoplasty combined with phacoemulsification.

OBJECTIVE: To report 1-year results and anterior segment optical coherence tomography findings of Descemet stripping automated endothelial keratoplasty combined with phacoemulsification in patients with cataract and Fuchs endothelial dystrophy. METHODS: Twelve eyes of 11 patients with at least 1-year follow-up were retrospectively reviewed. Measured variables included best spectacle-corrected visual acuity, refractive spherical equivalent and predictability, anterior corneal keratometric values, complications, and anterior segment optical coherence tomography findings. RESULTS: The mean follow-up was 14.33 months (range, 12-18 months). The best spectacle-corrected visual acuity was unchanged (8%) or improved (92%) in all eyes compared with the preoperative levels. A mean (SD) discrepancy between the targeted postoperative refraction and the actual postoperative spherical equivalent refraction (hyperopic shift) of 1.46 (0.76) diopters (D) (range, -0.05 to 3.14 D) was observed. A significant correlation existed between the ratio of central graft thickness to mean peripheral donor corneal lenticule thickness at 3 mm and induced hyperopic shift (R(2) = 0.65, P < .001). CONCLUSIONS: Descemet stripping automated endothelial keratoplasty combined with phacoemulsification and intraocular lens implantation in patients with coexisting Fuchs endothelial dystrophy and cataract improved best spectacle-corrected visual acuity without progressive time-dependent complications. A correlation exists between donor corneal lenticule shape and induced hyperopic shift.
