Comparison between different techniques for treatment of submacular haemorrhage due to Age-Related Macular Degeneration.

PURPOSE: To compare the outcome of vitrectomy, subretinal tissue plasminogen activator (TPA), and gas with and without subretinal air versus Intravitreal TPA and gas in the treatment of submacular haemorrhage (SMH) due to Neovascular age related macular degeneration. METHODS: We analysed the notes of 29 cases presented with SMH in the period between 01/2016 and 09/2018 at James Cook University Hospital. Presenting visual acuity (BCVA), size and location of SMH, Procedure done, final BCVA at 6 months and any surgical complications were recorded. 11 Cases (Group 1) received intravitreal TPA (50 µg in 0.1 ML), 0.3 ml of pure sulfur hexafluoride (SF6). 18 cases (Group 2) received 23 G Pars Plana vitrectomy, Subretinal TPA injection (25 µg in 0.1 ml), and 20% SF6 gas filling. Group 2 was further divided into 2A (10 patients) who received only subretinal TPA and group 2B (8 patients) who received additional 0.1 ml subretinal air. RESULTS: The mean BCVA at presentation was 0.0068 in group 1 and 0.0067 in group 2 (p = 0.8734). The mean postoperative BCVA at 6 months was 0.31 in group 1 and 0.58 in group 2 (p = 0.0015). Subgroup analysis of group 2 didn't show statistically significant difference in outcome when adding subretinal air to the vitrectomy procedure (p = 0.7009). CONCLUSION: Vitrectomy, gas and subretinal TPA has more successful displacement rate and better visual outcome than Intravitreal TPA & Gas alone in treating SMH involving the fovea in age-related macular degeneration. Additional subretinal air doesn't seem to improve the outcome in cases having vitrectomy.

Staphylococcus lugdunensis endophthalmitis following dexamethasone intravitreal implant.

We present a unique case of endophthalmitis with Staphylococcus lugdunensis following dexamethasone intravitreal implant for branch retinal vein occlusion associated with cystoid macular edema. Patient did not show favorable clinical response after vitrectomy and intravitreal antibiotics; so, we decided to repeat vitrectomy, remove the steroid implant and fill the eye with silicon oil, and repeat intravitreal vancomycin. Vision has improved from hand movements at presentation to counting fingers at 1.5 m after second vitrectomy and final visual acuity 3 months later after silicon oil removal was 6/36.

Pars Plana Vitrectomy with Internal Limiting Membrane Peeling in Traumatic Macular Hole: 14% Perfluoropropane (C3F8) versus Silicone Oil Tamponade.

PURPOSE: To evaluate the outcome of 23 G PPV and ILM peeling with 14% C3F8 compared with silicone oil tamponade in cases of TMHs without spontaneous closure. METHODS: A retrospective comparative study included 33 eyes with TMHs; 7 eyes healed spontaneously, and the remaining 26 eyes have been treated with PPV and ILM peeling. Silicone oil was used as a tamponade for children or adults who refused to adopt face-down position (10 cases). In all other cases (16 cases), 14% C3F8 was used. These cases were followed up for 6 months postoperatively. RESULTS: 26 cases (22 males and 4 females) were reviewed, including 10 cases treated with silicone oil and 16 cases treated with 14% C3F8. Patients' age ranged from 9 to 54 years. The success rate was 90% in the silicone-filled (9/10) and 94% in the gas-filled (15/16) eyes. At 6 months, the mean BCVA was 0.3 ± 0.25 in the silicone group and 0.2 ± 0.13 in the gas group (p < 0.05). CONCLUSIONS: Cases of TMHs should be observed for spontaneous closure. PPV with ILM peeling should be conducted for nonclosing cases. Gas and silicone oil tamponades are equally successful in anatomical and visual outcomes. This trial is registered with CTRI/2017/06/008765.
