Multicenter study of pars plana vitrectomy for optic disc pit maculopathy: MACPIT study

Comparison of subretinal aflibercept vs ranibizumab vs bevacizumab in the context of PPV, pneumatic displacement with subretinal air and subretinal tPA in naïve submacular haemorrhage secondary to nAMD. "The Submarine Study"

OBJECTIVE

To compare efficacy and safety profile of subretinal aflibercept, ranibizumab, and bevacizumab in the context of pars plana vitrectomy, pneumatic displacement with subretinal air and subretinal tPA for subretinal macular haemorrhage (SMH) due to naïve neovascular age-related macular degeneration (nAMD).

DESIGN

Retrospective interventional cohort study.

PARTICIPANTS

123 eyes of 123 patients treated with subretinal aflibercept (n = 41, 33%), ranibizumab (n = 41,33%), and bevacizumab (n = 41, 33%).

METHODS

Review of electronic medical records for best corrected visual acuity (BCVA), central subfoveal thickness (CST), and intraocular pressure (IOP) at baseline and 24 months after treatment.

MAIN OUTCOME MEASURES

BCVA, CST, and number of intravitreal anti VEGF over 24 months.

RESULTS

Mean age of patients was 80.5 ± 5.5 years, 43.9% were female. Mean time from symptom onset until surgery was 1.1 days (range 0-3 days). In all cases, the SMH did not reach the arcades. CST at baseline was 627 ± 140 µ, 739 ± 54 µ, and 793 ± 93 µ (p = 0.0001) for aflibercept, ranibizumab, or bevacizumab, respectively. Baseline BCVA (logMAR) was 0.65 ± 0.13, 0.69 ± 0.96, and 0.74 ± 0.81 (p = 0.0041) for aflibercept, ranibizumab, and bevacizumab, respectively. All three groups showed statistically significant improvement in BCVA and CST (for all groups: p < 0.001). There was no statistically significant difference at the final BCVA (p = 0.789). The mean number of anti VEGF given during follow-up period was 5.2 ± 0.81, 4.4 ± 0.63, and 5.5 ± 0.95 (p = 0.0001) for aflibercept, ranibizumab, and bevacizumab, respectively.

CONCLUSION

This study shows that aflibercept, ranibizumab, and bevacizumab in a subretinal manner in the context of PPV, pneumatic displacement with subretinal air and subretinal tPA for subretinal macular haemorrhage secondary to naïve nAMD work with the same efficacy and safety profile.

AUTOLOGOUS RETINAL TRANSPLANT FOR REFRACTORY SEROUS RETINAL DETACHMENT SECONDARY TO OPTIC DISK PIT: A NOVEL SURGICAL APPROACH

PURPOSE

To present a new technique to treat refractory retinal detachment secondary to optic disk pit.

METHODS

An interventional case report.

RESULTS

A 25-year-old man with congenital optic disk pit had two failed vitrectomies involving laser around the optic disk, internal limiting membrane peel and flap to plug the disk pit, and gas tamponade to reattach the retina. With all options running out, a further vitrectomy with autologous retinal transplant and silicone oil tamponade was performed to treat the refractory serous retinal detachment; the silicone oil was removed at 6 weeks after the last procedure. The retina remained successfully attached at 6 months postsurgery with the patient maintaining his baseline visual acuity.

CONCLUSION

The use of autologous retinal transplant is a new approach to treat refractory retinal detachment secondary to congenital optic disk anomalies, and adds to our options of dealing with this complex condition when first-line approaches have failed.

Inverted ILM Flap Technique in Optic Disc Pit Maculopathy

Purpose

To present the outcome of optic disc pit maculopathy (ODPM) managed successfully with an inverted internal limiting membrane (ILM) flap over the optic disc. A narrative review of ODPM pathogenesis and surgical management techniques are also provided.

Case Report

This prospective interventional case series included three eyes of three adult patients (25-39 years old) with unilateral ODPM and a mean duration of unilaterally decreased visual acuity of 7.33 ± 2.40 months (4-12 months). The pars plana vitrectomy with posterior vitreous detachment induction was performed on eyes, followed by an inverted ILM flap insertion over the optic disc and gas tamponade. Patients were followed for 7-16 weeks postoperatively; best-corrected visual acuity (BCVA) improved dramatically in one patient from 2/200 to 20/25. BCVA in other patients improved two and three lines - to 20/50 and 20/30, respectively. A significant anatomical improvement was achieved in all three eyes, and no complication was detected throughout the follow-up period.

Conclusion

Vitrectomy with inverted ILM flap insertion over the optic disc is safe and can yield favorable anatomical improvement in patients with ODPM.

Management of Optic Disk Pit-associated Macular Detachment with Human Amniotic Membrane Patch

PURPOSE

To report a new surgical technique involving a human amniotic membrane patch (hAM) to solve a serous macular detachment associated with optic nerve head pit.

METHODS

Three eyes of three patients affected by macular detachment associated with optic nerve head pit were enrolled. A 23-gauge pars plana vitrectomy were performed. hAM patch was implanted inside the optic nerve pit; air was used as endotamponade. The patients were instructed to maintain face-down position for the first days after surgery.

RESULTS

The subretinal fluid gradually resolved during 6 months of follow-up, and visual acuity improved to 20/25 at the sixth month after surgery. We did not observe a recurrence of subretinal fluid during the 6 months of follow-up. No postoperative complications were reported during the follow-up.

CONCLUSION

Implant of the hAM may be effective to repair optic disk pit maculopathy. All the cases were successful with encouraging visual acuity recovery.

Surgical Treatment of Optic Disc Pit Associated with Macular Detachment

We report a clinical case of a serous macular detachment associated with optic disc pit (ODP), which was successfully treated with vitrectomy and internal limiting membrane (ILM) flap technique. A twenty-four-year-old woman complained of visual loss with duration over 7 months. Upon ophthalmic examination using funduscopy and spectral domain optical coherence tomography (OCT), a serous macular detachment associated with optic disc pit was diagnosed. The patient was successfully treated by 25-gauge pars plana vitrectomy with ILM peeling and placing an autologous ILM flap to cover the optic disc including the ODP. This method of treatment resulted in complete retinal reattachment with best-corrected visual acuity improvement to 20/60 from initial 20/500, and OCT showed a complete retinal attachment. This clinical case suggests that 25-gauge vitrectomy with ILM peeling and an inverted ILM flap can be an effective treatment option for optic disc pit-associated serous macular detachment.

Optic Disk Pit Maculopathy Treatment Using a Human Amniotic Membrane Patch: One-Year Results

PURPOSE

To report the 1-year results of human amniotic membrane patch implantation for optic disc pit maculopathy.

DESIGN

A prospective, consecutive, interventional study.

METHODS

Eleven eyes of 11 patients affected by optic disc pit maculopathy associated with subretinal/intraretinal fluid were included in this single-institution study. A 25-gauge pars plana vitrectomy was performed in all cases, with an implant of a human amniotic membrane patch into the optic disc pit and air was injected as endotamponade. The primary study outcome was the subretinal and intraretinal fluid reabsorption. Secondary outcomes were visual acuity improvement and postoperative complications.

RESULTS

Mean central retinal thickness gradually diminished from 512 ± 137 µm to 243 ± 19 µm, at the 12-month follow-up. The mean visual acuity improved from 20/80 at baseline to 20/32 at the 12-month follow-up. Complete fluid resorption occurred in 9 of 11 (81.8%) eyes and there was partial resorption in 2 eyes (18%). No subretinal fluid recurrence was observed during the 12-month follow-up. No intraoperative or postoperative complications were reported during the follow-ups. The amniotic membrane patch remained detectable inside the pit for the entire follow-up time.

CONCLUSION

An amniotic membrane plug may be effective for improving optic disc pit maculopathy. All cases had an anatomical improvement and encouraging visual acuity recovery.

The outcomes of intravitreal C3F8 gas tamponade combined with laser photocoagulation treatment for optic disc pit maculopathy

Purpose

To share the anatomical results and visual outcomes of intravitreal gas tamponade combined with laser photocoagulation treatment for optic disc pit maculopathy (ODPM).

Methods

Intravitreal gas tamponade combined with laser photocoagulation treatment was performed on six consecutive patients with ODPM. A 0.3 mL of 100% perfluoropropane (C₃F₈) gas was injected intravitreally. The patients were then asked to maintain prone position until the C₃F₈ gas disappeared. Laser photocoagulation was performed the day after the procedure. The outcomes were determined by spectral-domain optical coherence tomography and best-corrected visual acuity (BCVA).

Results

In the present study, visual improvement and reduction in serous macular detachment were observed in 83% of the ODPM patients. Complete retinal reattachment was achieved in 66% of the ODPM patients. In one patient, no regression was observed after the repeated treatment, and pars plana vitrectomy was performed. The final BCVA improved in five eyes and unchanged in one eye. No postoperative complications were observed during the follow-up period in any patient.

Conclusions

Intravitreal C₃F₈ gas tamponade combined with laser photocoagulation procedure is an effective, minimally invasive, and cost-effective treatment method for ODPM.

Quantitative assessment of macular function after surgery for optic disc pit maculopathy: A case report

RATIONALE

We describe a case of optic disc pit maculopathy (ODP-M) in which vitrectomy with juxtapapillary laser (JPL) treatment led to the reattachment of retinoschisis (RS) as well as serous retinal detachment (SRD).

PATIENT CONCERNS

An 80-year-old man complained of distorted vision and decreased visual acuity (VA) in his left eye for 12 months.

DIAGNOSIS

We conducted quantitative functional evaluation on the area of RS and SRD using the Humphrey visual field analyzer. Fundus examination and optical coherence tomography showed SRD and RS in connection with the optic disc. The best-corrected logarithm of the minimum angle of resolution (logMAR) VA was 0.7.

INTERVENTIONS

The patient underwent JPL treatment combined with pars plana vitrectomy. During surgery, posterior vitreous detachment and tamponade were created with sulfur hexafluoride.

OUTCOMES

After surgery, SRD (and subsequently RS) gradually reduced and had completely disappeared at 31 months. VA gradually improved and was 0.0 (logMAR) at 28 months. The analysis of the mean macular thickness of the central 3-mm diameter showed that the macula thickness recovered to 300 μm at 17 months postoperatively. Retinal sensitivity began to improve at 24 months postoperatively and had increased at 48 months postoperatively.

LESSONS

In conclusion, vitrectomy with JPL treatment for ODP-M had a favorable anatomical outcome as well as a long-term functional outcome. These findings provide useful information for clinicians who are planning a therapeutic strategy, including the choice of surgical procedure for ODP-M.

INVERTED INTERNAL LIMITING MEMBRANE-FLAP TECHNIQUE FOR OPTIC DISK PIT MACULOPATHY: MORPHOLOGIC AND FUNCTIONAL ANALYSIS

PURPOSE

To analyze morphologic and functional changes after inverted internal limiting membrane-flap technique for optic disk pit maculopathy using optical coherence tomography, multifocal electroretinography, and microperimetry.

METHODS

One case report.

RESULTS

A 30-year-old woman presented us with decreased visual acuity (20/63) in the left eye because of retinoschisis and serous macular detachment associated with optic disk pit. Optical coherence tomography did not localize the source of intraretinal and subretinal fluid. A partial flattening of serous detachment after vitrectomy with internal limiting membrane peeling, inverted internal limiting membrane-flap technique, and gas tamponade was reported. Visual acuity and multifocal electroretinography improved while retinal sensitivity decreased at microperimetry during 3 months of follow-up.

CONCLUSION

Optical coherence tomography is helpful to assess the effectiveness of surgical maneuvers to treat optic disk pit maculopathy. Multifocal electroretinography and microperimetry might offer additional tools for follow-up analysis of retinal function after surgery.

Management of optic disc pit-associated maculopathy: A case series from a tertiary referral center

PURPOSE

To report outcomes of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) stuffing technique in patients with optic disc pit associated maculopathy (ODP-M).

METHODS

Data including best-corrected visual acuity (BCVA), central macular thickness (CMT), foveal center point thickness (FCP), and maximum height of fluid (max_fluid) (intraretinal or subretinal) were collected from the medical records of the patients.

RESULTS

Six eyes of six patients with a mean age of 28.0 ± 17.68 years (range: 9-53 year) underwent PPV + ILM plug surgery. The mean follow-up duration was 25.62 ± 26.11 months (range: 11.80-78.00 month) duration. The mean BCVA increased from 1.25 ± 1.04 logMAR (20/355, Snellen equivalent) to 0.86 ± 1.09 logMAR (20/144, Snellen equivalent) at last follow-up (p = 0.043). Compared to baseline, CMT, FCP, and max_fluid significantly decreased at all visits after the surgery (p < 0.05 for all visits). At last follow-up, 66.6% of the eyes (four eyes) showed complete resolution of fluid at a mean of 5.25 ± 4.99 months (range: 1-12 months) after the surgery.

CONCLUSION

PPV with ILM plug seemed to be an effective surgical technique in ODP-M. Studies with longer follow-up and higher number of patients are needed to confirm our results.

A Case of Multiple Optic Disc Pits: 21-Year Follow-up

Optic disc pits (ODP) are an uncommon congenital abnormality. Patients remain asymptomatic unless they develop maculopathy. The use of optic coherence tomography has critical benefits in the follow-up of patients who are at the amblyogenic age. The aim of this study is to present a case of double ODP in the right eye and single ODP in the left eye in a partially accommodative esotropia patient followed for 21 years. To our knowledge, multiple ODP has never been described in a patient with partially accommodative esotropia.

Intravitreal ranibizumab for the management of serous maculopathy secondary to optic disc coloboma-associated choroidal neovascularisation

We report the case of a 19-year-old patient with symptomatic unilateral serous maculopathy associated with an optic nerve coloboma. Fluorescein angiography detected a focal late leak at the temporal edge of the coloboma which was later found to correspond with an area of choroidal neovascularisation on optical coherence tomography angiography. A course of intravitreal ranibizumab achieved good clinical and structural response. This report contributes to the evidence that maculopathies associated with cavitary optic nerve anomalies may in some instances result from choroidal neovascularisation. It also highlights the importance of angiography to identify potential choroidal neovascular membranes, particularly in the absence of haemorrhages and neovascular membranes on fundus examination and conventional optical coherence tomography.

A prospective long-term follow-up study of optic disc pit maculopathy treated with pars plana vitrectomy, drainage of subretinal fluid and peeling of internal limiting membrane

PURPOSE

To describe the long-term results of surgical repair of patients with optic disc pit maculopathy (ODP-M).

METHODS

Prospective, consecutive, noncomparative follow-up study including 12 patients with ODP-M treated by pars plana vitrectomy (PPV), peeling of internal limiting membrane followed by gas tamponade. Subretinal fluid (SRF) was drained in 11 eyes through a retinotomy without laser photocoagulation. Preoperatively, macular detachment with retinoschisis was seen in 9 out of 12 eyes with three eyes having only subretinal fluid in the macular area. The median age at surgery was 20 years (range 9-60 years).

RESULTS

Follow-up time from initial surgery was 63 months (median). Eight eyes were anatomically reattached after one operation without remaining SRF in the macula. Two patients required a reoperation due to leakage from the retinotomy and another two underwent a second PPV procedure due to late recurrences. Successful healing was at follow-up control observed in 11 of 12 eyes. There was no statistically significant difference in visual acuity between patients before and after surgery (p = 0.24). Central visual field defects with depressed mean deviation were detected in all treated eyes.

CONCLUSION

In this long-term study of ODP-M final outcome regarding healing was relatively efficacious, however, a relatively large proportion had complications associated to retinotomies. We conclude that drainage of SRF should likely be avoided since it appears to contribute little to the resorption rate of SRF and seems to linked to unnecessary risks.

Surgical outcomes in patients with optic disc pit maculopathy: does peeling the ILM lead to better outcomes?

PURPOSE

Optic disc pits (ODPs) are rare congenital anomalies. Several patients develop optic disc pit maculopathy (ODP-M): visual impairment caused by intra- and/or subretinal fluid. Treatment mode remains controversial. This study was designed to investigate the effectiveness of pars plana vitrectomy (PPV) and gas tamponade with or without internal limiting membrane (ILM)-peeling in improving visual acuity and reducing subretinal fluid in ODP-M patients.

METHODS

We retrospectively reviewed the charts of 16 patients who underwent surgery for ODP-M from 2002-2015. Six patients underwent PPV with gas tamponade (group 1); ten patients additionally received ILM-peeling (group 2). Pre- and postoperative visual acuity and central retinal thickness (CRT) were compared between groups, as well as retinal morphology and the number of secondary vitrectomies and complications.

RESULTS

Median visual acuity improved by 2 ETDRS lines in both groups (p = 0.713, Mann-Whitney U test). Median CRT decreased by 426.5 µm and 460 µm (p = 0.931). One patient in group 1 underwent repeat vitrectomy for persistent retinoschisis. Three patients in group 2 required repeat vitrectomy: two to treat a macular hole, one for peripheral retinal holes with retinal detachment.

CONCLUSION

In our cohort, PPV with gas tamponade proved to be an effective first-line treatment for ODP-M. Additional ILM-peeling did not give a significant benefit in this study.

Surgical Options for Optic Disc Pit Maculopathy: Perspectives and Controversies

Optic disc pit (ODP) is a rare congenital optic nerve head abnormality, which can be complicated by intraretinal and subretinal fluid at the macula (ODP-maculopathy) with progressive visual loss. The source of this fluid remains unclear and the most dominant hypotheses have pointed to vitreous cavity or cerebrospinal fluid. Although spontaneous resolution has been reported, the majority of untreated cases of ODP-maculopathy result in final visual acuity less than 20/200 or worse. A wide array of interventions, either individually or in combination with adjuvant treatments, have been tried with varying degrees of success. Recently, different surgical procedures to fill the ODP by self-sealing materials in combination with pars plana vitrectomy have been reported as an effective adjuvant treatment. However, given the relative rarity of this condition, the majority of reports describe a small retrospective case series, making it difficult to compare among different treatments options and create a consensus regarding the optimal treatment for ODP-maculopathy. In this situation, a mini-review about surgical treatment modalities and their results can be a useful approach to identify the most effective surgical option in the management of ODP-maculopathy.

Sulphur hexafluoride (SF6) intravitreal injection combined with argon laser photocoagulation for treatment of optic disc pit maculopathy

PURPOSE

To evaluate clinical efficacy of combined sulphur hexafluoride (SF6) gas tamponade and laser photocoagulation for optic disc pit maculopathy (ODPM).

METHODS

Eleven eyes of nine patients with optic disc pit maculopathy were treated with intravitreal injection of 0.6 ml 100% sulphur hexafluoride (SF6) combined with laser photocoagulation treatment. Patients were followed up for a mean of 28.54 months (range of 14-57 months) after treatment. The anatomical success was shown by optical coherence tomography (OCT) and the functional outcome was judged by best corrected visual acuity.

RESULTS

Treatment with SF6 gas tamponade followed by laser photocoagulation in OPDM patients resulted in resolution of subretinal fluid (SRF) in 82% of eyes after single injection. Repeated injection was needed in two eyes to achieve resolution of SRF. Visual acuity improved significantly from a mean of 0.83 ± 0.14 logMAR preoperatively to a mean of 0.26 ± 0.11 logMAR postoperatively. Visual acuity stayed stable throughout the follow-up period.

CONCLUSIONS

SF6 gas tamponade combined with laser photocoagulation represents simple, effective, minimally invasive treatment option for ODPM without vitreomacular traction. Repeated injection was required in some patients.

Optic Disc Pit Maculopathy: New Perspectives on the Natural History

PURPOSE

To investigate the natural history of optic disc pit maculopathy and explore the associations between demographic, anatomic, and functional characteristics.

DESIGN

Retrospective, comparative case series.

METHODS

This was a single-center medical record review of previously untreated optic disc pit maculopathy. Baseline data of visual function, demographics, and pit physiognomy were collected, and further subgroup analysis was undertaken on patients with long-term follow-up, according to whether they were monitored or received surgical intervention. LogMAR visual acuity was the primary outcome measure, and anatomic characteristics were reported where available.

RESULTS

Eighty-seven patients were identified with a new presentation of optic disc pit maculopathy. No demographic or pit features were correlated with vision at baseline. In 51 patients with available optical coherence tomography data, only the presence of subretinal fluid at baseline was associated with poorer visual acuity (P < .001). Fifty-two patients who were monitored without treatment had available long-term follow-up data. The mean change in visual acuity in this group was 0.01, with 77% maintaining visual acuity ≤0.30. Twenty-seven patients underwent surgery and showed significant postoperative improvement in vision (P < .001), with 59% achieving an acuity ≤0.30. Duration of postoperative follow-up was associated with better visual acuity (P = .007).

CONCLUSION

Many patients with optic disc pit maculopathy maintain good long-term visual acuity and may demonstrate resolution of subretinal fluid in the absence of surgical intervention. There may be evidence to support delaying surgical treatment until visual deterioration is observed because of the potential stability or spontaneous improvement of the condition, the high rate of reoperation, and the long-term positive outcomes of deferred intervention.

Optic disc pit maculopathy: tamponade of maculoschisis

Purpose

To present rapid and safe closure of the pit-macula communication (PMC) by core vitrectomy and adequate duration gas tamponade as our preferred method of resolving optic disc pit (ODP) maculopathy and to define the term "maculoschisis" in ODP maculopathy as an alternative to the term "schisis-like."

Patient and methods

A twenty-four-year-old female presented with an optical coherence tomography (OCT) confirmed ODP and a "giant" communicating maculoschisis cavity. Central macular thickness (CMT) measured 906 microns, and macular volume was twice normal, at 20.8 mm³. Snellen corrected visual acuity was 20/70. Two months after initial vitrectomy performed elsewhere with short-term gas tamponade (SF₆ 20%), CMT and visual acuity were not significantly improved. Combined lens extraction/intraocular lens placement and repeat vitrectomy with C₃F₈ 15% gas tamponade were performed, with one supplemental (office) gas injection.

Results

OCT imaging six weeks postoperatively showed definitive closure of the PMC with CMT reduced by 405 microns. Sequestered from its ODP source, foveal schisis fluid then resolved by 12 weeks postoperatively. At final follow-up 3.4 years postoperatively, the macula remained dry with a CMT of 322 microns and a concave foveal contour. Macular volume was reduced to (a normal) 10.2 mm³ and visual acuity had improved to 20/25.

Conclusion

No report heretofore has documented rapid, sustained closure of the PMC by gas tamponade as the preferred method of expeditiously resolving ODP maculopathy. However, tamponade PMC closure sequesters ODP fluid and uniquely provides early assurance of ultimate maculopathy resolution. In all other techniques, PMC closure is a trailing phenomenon and success remains uncertain during months to a year or more of (unsequestered) fluid resolution. We suggest that more invasive techniques (laser barrier application to the peripapillary choroid, vitreoretinal interface maneuvers, and pit-plugging) be withheld unless a recurrence is detected during subsequent examinations.

[Macular changes in optic disc pits-Optic disc pit maculopathy (ODP-M) : Pathophysiology and possibilities of surgical treatment]

An optic disc pit is a rare congenital abnormality of the optic nerve, which in most cases presents as a unilateral finding. Clinically, a greyish oval excavation is seen, most commonly on the temporal side of the optic nerve disc. The optic disc pit alone normally does not lead to substantial symptoms or functional limitations; however, when a maculopathy with intraretinal and/or subretinal fluid and additional other morphological changes in the macula occur, this leads to a decrease in visual acuity. With spectral domain optical coherence tomography (SDOCT) it is possible to identify the various forms of expression, which show different natural courses. Especially the presence of subretinal fluid and defects in the outer retinal layers have a poor prognosis and have the highest risk for further deterioration. Spontaneous resolution can occur but is rare. Observation is recommended in the first step. In cases of progression or pronounced deterioration, surgical intervention is indicated. Many different techniques have been proposed but there is no gold standard at the moment. Most of the surgical approaches comprise pars plana vitrectomy with peeling of the internal limiting membrane (ILM) and gas endotamponade. Newer methods, such as the ILM flap technique also show good results. Generally, it is important to know that postoperative healing and resorption of the fluid often take a long time period of up to 1 year or even longer.

Optic disk pits and optic disk pit maculopathy: A review

Optic disk pit, one of the optic disk cavitary anomalies, is generally congenital and unilateral and occurs equally in males and females. Optic disk pit maculopathy is characterized by intraretinal and subretinal fluid at the macula, causing visual deterioration. The origin of the macular fluid and the mechanism of transition to the subretinal space in optic disk pit maculopathy pathophysiology are not yet fully understood. With the evolution of imaging modalities, especially optic coherence tomography, our knowledge of this disorder continues to increase. Although many different treatments have been tried, there is no consensus on the most effective.

Optic disk pit maculopathy: current management strategies

Introduction

Optic disk pit (ODP) is a rare congenital abnormality of the optic nerve head and can lead to visual impairment when macular detachment occurred. Recent advances in retinal imaging brought new insights into the pathophysiology of the disease, while new therapeutic options have been also described.

Methods

We made a comprehensive search of the literature regarding the current treatment modalities for the treatment of ODP maculopathy.

Results

Although there have been reported some cases of spontaneous resolution, current management of ODP maculopathy involves several surgical approaches. The most commonly used treatment alternative for ODP maculopathy management is vitrectomy, either alone or in combination with other treatment modalities, such as gas tamponade or laser photocoagulation. Other options, such as scleral buckling and inner fenestration, are also used, based on the recent findings about pathophysiology of the disease.

Conclusion

The management of ODP maculopathy remains challenging. Even though there are further advances in the understanding of the disease pathophysiology, the applied treatment is not single and therapeutic modalities differ in the success rate, related to the anatomical and functional results.

Optic Disc Pit Maculopathy: A Two-Year Nationwide Prospective Population-based Study

PURPOSE

To identify the incidence, presenting features, treatment, and clinical course of optic disc pit maculopathy (ODPM) in the United Kingdom (UK).

DESIGN

A 2-year nationwide prospective population-based study.

SUBJECTS

All new incident cases of ODPM presenting to UK ophthalmologists using the British Ophthalmic Surveillance Unit monthly reporting system.

METHODS

All reporting ophthalmologists were sent an initial questionnaire requesting data on previous medical and ophthalmic history, presentation details, investigation findings, and management. A further questionnaire was sent at 12 months post diagnosis to ascertain further outcome data.

MAIN OUTCOME MEASURES

Visual acuity at initial presentation, at 1 year, and after any intervention. Foveal involvement and optical coherence tomography (OCT) findings, including retinal layers affected, and the location and size of the optic disc pit. Management, including observation, vitrectomy, and associated procedures.

RESULTS

There were 74 confirmed new cases, giving an annual incidence of approximately 1 per 2 million. Complete data were available on 70 patients (70 eyes) at baseline and 68 after 1 year. There were 35 (50%) female patients with a mean age of 35 years (range, 3-82 years). Visual acuity at baseline ranged from 6/5 to hand movements. In 43 patients (61%) subretinal fluid (SRF) was present, whereas 27 (39%) had intraretinal fluid only. The presence of SRF was associated with worse vision and foveal involvement. Of the 53 eyes initially observed with 1-year follow-up, 10 (19%) deteriorated and 9 (16%) improved on OCT; eyes with SRF were more likely to worsen and those without SRF were more likely to improve. Fifteen of the 70 patients (21%) at baseline had primary surgery and a further 10 had deferred surgery within 1 year of presentation; 19 of these 25 eyes (76%) showed anatomic success with a dry fovea at 1 year of follow-up, and 15 (60%) had a greater than 0.1 logMAR improvement in visual acuity.

CONCLUSION

The incidence and presenting features of ODPM were defined. Patients with SRF had worse vision and were more likely to deteriorate than patients with intraretinal fluid only. Surgery was anatomically successful in 75% of cases. Patients without SRF tended to remain stable with observation.

Micropulse laser for persistent optic disc pit maculopathy. A case report

Purpose

Optic disc pits (ODP) are rare and congenital anomalies of the optic disc, sometimes remaining asymptomatic. However, serous macular detachment or optic disc maculopathy is the most common complication, causing significant visual deterioration, without a current consensus about treatment. We describe a case of ODP maculopathy that was treated successfully with micropulse laser.

Observations

A patient with ODP maculopathy remained with macular serous detachment after nine months of follow up after pars plana vitrectomy. Subthreshold micropulse laser was used to treat macular serous detachment, achieving a significant improvement in central macular thickness after one session.

Conclusions and importance

Subthreshold micropulse laser is designed to stimulate the retinal pigment epithelium without damage to the photoreceptors, resulting in absorption of subretinal and intraretinal fluid. Macular serous detachment in patients with ODP requires a prompt diagnosis and treatment to avoid damage to photoreceptors. Subthreshold micropulse laser is a potential treatment for eyes with ODP and macular serous detachment complication.
