“…Therefore, we expect our actual reattachment rate to be higher, as 56% of the patients in our study had a follow-up time of less than 1 year. However, successful repair of these chronic and/or refractory macular detachments may be limited by reduced function of the retinal pigment epithelium-Bruch’s membrane complex, as well as by degeneration within the retinal layers [13, 32]. In our study, we did not find any clear advantage of one surgical ILM technique over another regarding the final reattachment rate.…”

Purpose: To compare the anatomical and functional outcome of adjuvant pars plana vitrectomy (PPV) procedures using the techniques of translocation of an internal limiting membrane (ILM) flap and transplantation of an inverted ILM flap for the treatment of chronic and/or refractory optic disc pit (ODP) maculopathy. Methods: In this prospective interventional case series study, 9 patients (9 eyes) with chronic and/or refractory ODP maculopathy underwent PPV with either translocation of an ILM flap or transplantation of an inverted ILM flap as adjuvant techniques along with gas tamponade. The anatomical success, rates of macular reattachment, and visual improvement were assessed. Results: The mean preoperative central retinal thickness (CRT) was 723.4 µm (range: 366–1,151). The mean postoperative CRT was 398.1 ± 212.2 µm (range: 210–758). An increased preoperative CRT was associated with a lower chance of postoperative reattachment of the macula (p = 0.047). The overall reattachment rate at the end of the follow-up period was 56% (n = 5). The mean preoperative visual acuity (logMAR unit [Snellen acuity]) was 0.48 (20/60) (range: 1.30 [20/400] to 0.10 [20/25]). The mean change in best corrected visual acuity (BCVA) was 0.48 ± 0.233 logMAR units (approx. 3 lines of visual improvement). Conclusions: ILM flap techniques are logical and straightforward approaches as adjuvants to PPV treatment of ODP maculopathy. They could be viable adjuvant treatments for improvement in BCVA and CRT in patients with ODP maculopathy.

“…The first description was of a case successfully treated with injection of autologous platelets over the ODP [86]. Other techniques designed to seal the ODP include using an autologous scleral flap [87], inverting peeled ILM into the ODP [88], and using Tisseel fibrin sealant [89]. …”

Optic disc pit maculopathy: when and how to treat? A review of the pathogenesis and treatment options

2015

View full text Add to dashboard Cite

Optic disc pit (ODP) is a rare congenital anomaly of the optic disc, which can be complicated by a maculopathy associated with progressive visual loss. Optic disc pits are usually unilateral and sporadic in occurrence, and the development of maculopathy is unpredictable with no known triggers. Optic disc pit maculopathy (ODP-M) is characterized by intraretinal and subretinal fluid at the macula, causing visual deterioration. The source of this fluid is still unclear, and several competing theories have suggested it may be vitreous fluid, cerebrospinal fluid, leakage from blood vessels at the base of the pit or leakage from the choroid. The mechanism of pathogenesis of ODP-M has not been fully elucidated, but vitreous liquefaction and traction and pressure gradients within the eye have been implicated to be involved. There are no clear guidelines on the management of patients with ODP-M, and numerous techniques have been described, including laser photocoagulation, intravitreal gas injection, macular buckling and pars plana vitrectomy with many different modifications. The majority of reports describe small series, and as there are no comparative studies there is no consensus regarding the optimal treatment for ODP-M. This review discusses the literature on the possible sources of fluid and mechanisms of pathogenesis in ODP-M, as well as the wide array of treatment modalities and their results. Based on these, a set of recommended key concepts for the timing and choice of treatment for these challenging are presented.

“…Investigations include OCT which demonstrates a bilaminar structure [5] and visual fields which may show arcuate scotomas or an enlarged blind spot [1, 2]. Although ODP position and field defects do not always correspond [2], it has been hypothesised previously that damage to the nerve fibre layer may cause the visual field defects [3].…”

“…Treatment of maculopathy includes standalone laser or vitrectomy with or without laser [1, 2, 5]. If left untreated, the visual prognosis is poor [1, 2, 5].…”

A Rare Case of Symptomatic Double Optic Disc Pit without Maculopathy

Optic disc pits are an uncommon congenital abnormality. Patients remain asymptomatic unless they develop maculopathy. We present a rare case of a double optic disc pit of which only three others have been reported worldwide. A 51-year-old gentleman presented with blurred vision. Fundoscopy revealed a right double optic disc pit. Though he was symptomatic there was no evidence of maculopathy. OCT of macula and disc was otherwise unremarkable. Visual field demonstrated a paracentral defect. Although optic disc pits are rare they are still an important clinical entity. Prompt identification and treatment of complications are required to prevent a poor visual prognosis.
