![]() Cooling the infusion fluid from body to room temperature extended the damage threshold from approximately 25 to 60 minutes.ĭamage was determined ophthalmoscopically and histologically. A 35-minute exposure to body temperature fluid was compared with the same exposure during infusion of room temperature fluid. ![]() While retinal and retinal pigment epithelium damage was present after the body temperature exposure, no damage was detected after the room temperature exposure. Vitreoretinal surgeons should avoid warming intraocular infusion fluids to levels above room temperature. To compare the complications leading to best-corrected visual acuity (BCVA) loss in patients with Boston keratoprosthesis type 1 (KPro) and glaucoma drainage device (GDD) and those with KPro alone. Retrospective case series of all patients who underwent KPro surgery at the Centre Hospitalier de l'Université de Montréal between 20. BCVA and complications were tabulated and analysed. KPro surgery was performed in 96 eyes: 18 eyes (19%) had KPro and GDD while 78 eyes (81%) had KPro only. Median BCVA at postoperative 6 months was 20/150 in both groups. Seven eyes (39%) with KPro and GDD experienced vision loss due to complications such as glaucoma progression (three eyes, 22%), tube occlusion (four eyes, 22%) and choroidal haemorrhage (three eyes, 17%). Vitreous incarceration was the most common cause of tube occlusion. Vitreoretinal, glaucoma and infectious complications caused BCVA loss in 16 eyes (21%) with KPro alone (p=0.13). Glaucoma progression is a major cause of visual decline post-KPro. However, GDD implantation should only be performed in carefully selected patients. Because of a high risk of vitreous incarceration within the tube, a complete pars plana vitrectomy should be performed prior to GDD implantation. To assess correlation between preoperative and postoperative findings and surgical factors, and postoperative functional outcomes after successful repair of acute macula-off rhegmatogenous retinal detachment (RRD).įorty-four eyes of 44 patients with recent-onset macula-off RRD who had primary pars plana vitrectomy were included in this retrospective study. visual acuity (BCVA) and retinal and choroidal changes on spectral-domain optical coherence tomography (SD-OCT) were evaluated before and after surgery. Correlation between preoperative and postoperative variables such as demographic and clinical data, SD-OCT findings and surgical factors, and postoperative functional outcomes were assessed.Įighteen women and 26 men, whose mean age at the onset of RRD was 51.7 ± 14.4 years, were evaluated. The mean preoperative and postoperative logMAR BCVA were 1.1 ± 0.5 (20/250) and 0.14 ± 0.1 (20/30), respectively, after a mean of 16.7 ± 7.2 months. Although all factors were evaluated as prognostic factors for functional outcome after surgical treatment of recent-onset macula-off RRD, epiretinal membrane formation was found as the only factor affecting postoperative visual acuity.
