RESUMEN

Background: A 40-year-old male presented with a complaint of sudden onset diminution of vision in the left eye for 2 weeks. He was a follow-up case with retinal hemangioblastoma in both eyes. He underwent two sittings of fundus fluorescein angiography-guided trans-pupillary thermotherapy 2 years back. Since then, he was regularly followed up for 2 years with stable vision and stable retinal findings. At present, the best-corrected visual acuity (BCVA) in the right eye is 6/6, and in the left eye, it is counting fingers 2 meters. On fundus examination, he had one active hemangioblastoma in the right eye and total retinal detachment in the left eye with multiple active lesions. The right eye was treated with a single sitting of thermotherapy, and the left eye underwent pars plana vitrectomy and angioma excision, followed by silicone oil tamponade. The immediate and late post-operative periods were uneventful, with successful anatomical and functional outcomes. The left eye BCVA on late follow-up was 6/36, no further treatment was advised, and the patient was kept under follow-up and observed closely. Purpose: : To educate regarding the systemic workup, diagnosis, and surgical management of complicated retinal detachment in retinal hemangioblastoma. Synopsis: : Systemic workup, diagnosis, and surgical steps in the management of complicated retinal detachment in retinal hemangioblastoma were performed. Highlights: : Close follow-up, keen observation, and prompt treatment in the early stages of the disease are indispensable to prevent untoward sequelae of retinal hemangioblastoma. A thorough systemic workup is necessary to diagnose the systemic involvements early. Surgery, if indicated for the retinal hemangioblastoma or its associated sequelae, should be performed diligently and with careful handling of blood vessels and anomalous tissues.

RESUMEN

Objectives: To evaluate the efficacy and safety of heavy silicone oil as an endotamponade in patients with recurrent or complicated retinal detachment and macular hole. Materials and Methods: Nineteen eyes of 19 patients who underwent heavy silicone oil endotamponade for different indications were included in the study and evaluated by retrospective chart review. At each visit, patients underwent detailed ophthalmological examination and anatomical and functional outcomes, silicone oil emulsification, intraocular inflammation, presence of proliferative vitreoretinopathy, preoperative and postoperative visual acuity, and postoperative complications were recorded. Results: The study included 19 eyes of 19 consecutive patients: 13 women (68.4%) and 6 men (31.6%). The patients' median age was 60 years (interquartile range [IQR]: 44-70 years) and the median follow-up time was 19 months (IQR: 9-31 months). Indications for heavy silicone oil endotamponade were recurrent retinal detachment in 11 eyes (57.8%), inferior retinal detachment in 5 eyes (26.3%), inferior rhegmatogenous retinal detachment, recurrent macular hole in 2 patients (10.5%), and macular hole in 1 patient (5.2%). Median best corrected visual acuity was 2 logMAR (IQR: 1-2.6) preoperatively and 0.99 logMAR (IQR: 0.4-2) postoperatively (p<0.001). Postoperative anatomical success was achieved in all patients. Densiron 68 was used for endotamponade in 14 patients (73.7%), Densiron XTRA in 3 patients (15.8%), and AlaHeavy 1.07 in 2 patients. Heavy silicone oil emulsification was observed in only 3 patients (15.8%). Conclusion: Although heavy silicone oil has limitations as an endotamponade, such as intraocular pressure increase, emulsification, intraocular inflammation, and the risk of complications during removal, it is a safe and effective alternative in eyes requiring inferior retinal tamponade for indications like proliferative vitreoretinopathy and recurrent macular holes.

RESUMEN

INTRODUCTION: This study aimed to evaluate the effectiveness of vitrectomy without using perfluorocarbon liquid (PFCL) for the treatment of complicated retinal detachment (RD). METHODS: The utilisation of PFCL was calculated in four hospitals in 2020 and in one hospital every year from 2012 to 2020. A case series of 320 RD eyes treated with vitrectomy without the use of perfluorocarbon liquid (VWTPL) was followed up for 1-26 months. The rate of retinal reattachment (RR) and postoperative visual acuity (VA, LogMAR) was evaluated. Furthermore, factors influencing RR and VA were analysed. RESULTS: The overall utilisation of PFCL was 43.87% (42.74%, 45.83%, 62.39% and 4.5%). The annual utilisation was 46.94%, 20.43%, 46.73%, 47.41%, 20%, 17.24%, 7.60%, 10.67% and 4.49% from 2012 to 2020. The VA of 320 eyes improved from 1.96 ± 1.07 preoperatively to 1.43 ± 0.92 (LogMAR, p < 0.001) 1 week post-operation. In the follow-up of 1-26 months (median: 9 months), the primary and final RR was 87.37% and 95.56%, respectively. Age, uveitis, recurrent RD, the number of detached retinal quadrants, aPVR and preoperative VA were considered as the factors influencing postoperative VA. Moreover, preoperative VA and preoperative intraocular pressure were the factors influencing RR. CONCLUSION: The utilisation of PFCL varies amongst hospitals with a highest percentage of 62.39%. VWTPL is safe and effective, thereby saving costs and preventing complications related to PFCL. TRIAL REGISTRATION: ChiCTR-ORC-17014225.

RESUMEN

Purpose: To determine the predictors for visual outcome after silicone oil removal (SOR) in eyes with complicated retinal detachment. Patients and Methods: A total of 182 eyes with complicated retinal detachment that had undergone SOR were retrospectively reviewed. Snellen best-corrected visual acuity (BCVA), intraocular pressure (IOP) and complications were recorded at baseline, 1 day, 1 month and 3 months postoperatively. Good visual outcome was defined as best-corrected visual acuity of ≥20/200 at 3 months visit. Factors predicting visual outcome were evaluated using univariate and multivariate analysis. Results: After SOR, anatomical retinal reattachment was noted in 165 eyes (90.66%). Good visual outcome (VA ≥ 20/200) was achieved in 104 eyes (57.14%) at 3 months after SOR. For the eyes that remained attached after SOR, the percentage of good visual outcome was 63.03%. With univariate and multivariate analysis, visual acuity before SOR (p<0.001), circumferential peripheral retinopexy (p=0.037), additional endolaser during SOR (p=0.004), and pseudophakia status at the last follow up (p=0.021) were associated with visual outcome. Complications after SOR included redetachment (9.4%), hypotony (6.6%) and bullous keratopathy (1.7%). Conclusion: While anatomically attached retina was achieved in most of the patients, the functional outcomes were still much lower. Good BCVA before SOR and pseudophakia status at the last follow up were predictors for good visual outcomes, whereas circumferential peripheral retinopexy and additional endolaser during SOR were predictors for poor visual outcomes after SOR in eyes with complicated retinal detachment.

RESUMEN

AIM: To evaluate the safety and efficacy of Densiron 68 heavy silicone oil (HSO) tamponade for complicated retinal detachment (RD) in Chinese eyes. METHODS: Twenty-one eyes of 21 patients with complicated RD were included in this retrospective study. All patients underwent pars plana vitrectomy with an internal tamponade using Densiron 68 HSO. Anatomical and functional results and complications were evaluated, including retinal status, visual acuity (VA), intraocular pressure (IOP), intraocular inflammation, lens opacity, and HSO emulsification. RESULTS: All the patients were followed up for 3mo to 1y (5.8±1.16mo). Retinal reattachment was achieved in 19 of 21 patients (90.5%). VA improved in 18 of 21 patients (85.7%), from 1.93 logMAR (±0.48) to 1.52 logMAR (±0.45) (P=0.001). Postoperative complications included early dispersion of HSO in 7 eyes (38.8%), cataract in 10 of 18 phakic eyes (55.5%), moderate postoperative inflammation reaction in 10 eyes (47.6%), and elevated IOP in 5 eyes (23.8%), all of which were controlled by medication or by surgery. CONCLUSION: High anatomical and functional success rates can be achieved with primary vitrectomy for complicated RD by using Densiron 68 HSO; however, it should not be ignored that Densiron 68 HSO can cause some complications in the eye.

RESUMEN

Perfluorocarbon liquids have been shown to be a useful intraoperative adjunct in managing complicated retinal detachment. To prove the effectiveness of intraoperative use of perfluorocarbon liquid and the improvement of surgical and functional outcomes, we retrospcetively evaluated the clinical results of the patients[13 eyes]who had retinal detachment complicated with proliferative vitreoretinopathy [over PVR Grade C4, C4 :7 eyes, C5 :6 eyes]. We performed standard 3-port pars plana vitrectomy in all eyes included in this study.Perfluorodecalin[DK-line]was used as a shortterm vitreous substitute intraoperatively and removed before the end of the surgery. The mean follow-up period was 15 months.Anatomical success rate was 86%[6 eyes]in Grade C4, 67%[4 eyes]in Grade C5, Visual acuity was over 5/200 in one eye[8%]and there was improvement in 5 eyes[40%] although it was below 5/200. Consequently, we could easily manage the retinal detachment with PVR with help of intraoperative perfluorocarbon liquid and could improve the postoperative surgical and visual outcomes.

RESUMEN

23 eyes of 23 patients who underwent conventional vitreoretinal surgery with high specific gravity perfluorocarbon liquid, perfluorophenanthrene, for complicated retinal detachment were evaluated retrospectively. Preoperative vitreoretinal findings showed grade C2 PVR in 4 eyes and C3 in 1 eye and C4 in 10 eyes and C5 in 8 eyes. As a result, 17 eyes(74%) showed anatomical success, completely reattached in 15 eyes, partially reattached in 2 eyes, and 12 eyes(52%) showed functional success (corrected visual acuity 5/200 or better). Follow-up period was over 6 months in all cases. Postoperative complications includes keratopathy in 6 eyes, hypotony in 5 eyes, cataract in 2 eyes, transient vitreous hemorrhage in 1 eye, acute increased IOP in 1 eye, posterior synechiae in 1 eye, cystoid macular edema in 1 eye, and pupillary membrane in 1 eye. Consequently, perfluorophenanthrene can be used beneficially in yield of surgical field and mechanical stabilization of retina in complicated retinal detachment surgery.

RESUMEN

An improved retinal tack and applicator have been increasingly used as an adjunct in the repair of complicated retinal detachments. We used this technique in 7 consecutive cases of complicated retinal detachment. After a mean follow-up of 3 months, anatomical reattachment including partial reattachment was achieved in 5 eyes among 7 eyes, and 6 eyes had improved vision or no change(one improved to 20/70). Retinal tacks appear to be a useful tool either temporarily or permanently in preventing retraction and detachment of the retina until adjunctive diathermy, cryopexy, or photocoagulation becomes effective.
